Gasification principle

Biomass downdraft gasifier construction scheme uses biomass to generate power from rice husk wood scraps municipal waste supplier

Biomass raw materials enter into the reactor of gasifier, which is heated and dried. Then, with the increase of temperature, the volatile matter is separated out and pyrolyzed (cracked) at high temperature. The pyrolysis gas and biomass react with the air supplied in the oxidation zone to produce CO2 and steam. The heat generated by combustion is used to maintain the endothermic reaction of drying, pyrolysis and lower reduction zone. The gas generated after combustion will go down through the reduction zone and react with the high temperature carbon layer (C+ CO2 = 2CO, C + HO2 = H2 + CO) to generate biomass syngas containing Co, H2, CH4, CMHN and other components, which is led out from the lower part and sent out for use after the tar and other impurities are removed by the purification system. The ash is discharged from the lower part of the gasifier.

Why choose biomass gasification power generation equipment?

Answer:

At present, there are three ways to treat agricultural and forestry waste and domestic waste: (1) landfill, (2) waste incineration and power generation; and (3) garbage composting.(1) Landfill: with a large amount of land, landfill does not reduce the amount of waste. For a large amount of domestic waste, a huge landfill site is needed, which makes it difficult to select a new landfill site; The landfill site has a high risk of environmental pollution, and the domestic waste landfill site does not deal with the pollution source effectively. With the increase of the storage and the extension of the time, it is easy to cause leakage and pollute the surrounding environment such as soil and groundwater; After many years, the MSW in landfills is easy to mineralize. The mineralized landfills are not suitable for re cultivation, so it is more difficult to treat them again. (2) Waste incineration for power generation: 90% of dioxins in the atmospheric environment come from municipal and industrial waste incineration. Dioxins in the flue gas of municipal solid waste incineration (MSW) is a common concern in the world in recent years. Dioxin like highly toxic substances cause great harm to the environment. Effective control of the generation and diffusion of dioxins is directly related to the promotion and application of waste incineration and waste power generation technology. A study by Japanese researchers shows that the accumulation of dioxin in the mother's body can also aggravate children's autism tendency. Dioxins are the representative of environmental endocrine disruptors. They can interfere with the endocrine system of the body and have a wide range of health effects. Dioxin can cause ovarian dysfunction in female animals, inhibit the effect of estrogen, make female animals infertility, reduce the number of fetuses, abortion and so on. Low dose of dioxin can cause cleft palate and hydronephrosis. The male animals treated with dioxin had decreased spermatocytes, degenerated mature sperm and feminized male animals. Dioxin has obvious immunotoxicity, which can cause thymus atrophy, cell immunity and humoral immunity function decrease. Dioxins can also cause skin damage. Skin hyperkeratosis, pigmentation and chloroacne can be observed in exposed experimental animals and people. Dioxin can cause liver enlargement, parenchymal cell proliferation and hypertrophy, and degeneration and necrosis in severe cases. Compared with rural areas, the air in urban, industrial areas or areas close to pollution sources contains higher concentrations of dioxins. The amount of dioxin exposed by respiratory route in general population is very small, which is estimated to be about 1% of the intake through digestive tract, which is about 0.03pgteq (kg/ D). In some special cases, the amount of dioxin exposed by respiratory pathway should not be ignored. The survey shows that the dioxin content in the blood of waste incineration employees is 806pgteq / L, which is about 40 times of the level of normal people. Dioxins discharged into the atmosphere can be adsorbed on the particulate matter, settle into the water and soil, and then enter the human body through the enrichment of food chain. Food is the main source of dioxins in human body. Trans placental and lactation can cause dioxin exposure in fetuses and infants. People who are in constant contact are more likely to get cancer. (3) Garbage composting: it takes a long time to treat garbage, and the effect of waste volume reduction is poor. The applicable range of garbage is small, and it is generally used for domestic waste. The fertilizer effect of compost production is not as good as that of chemical fertilizer, the sales volume is not good, and the enthusiasm of manufacturers is not great. Because of the large amount of domestic waste composting and low nutrient content, the long-term use of domestic waste is easy to cause soil hardening and groundwater quality deterioration, so the scale of composting is not easy to be too large, and the current composting technology is not mature.

Biomass gasification power generation: agricultural and forestry waste gasification power generation technology, referred to as biomass gasification power generation technology, uses biomass gasification equipment to convert solid biomass (vegetable leaves, branches, organic domestic waste, agricultural and forestry waste, etc.) into combustible biomass syngas. By controlling the reaction process, carbon, hydrogen and oxygen are chemically reacted to synthesize carbon monoxide and hydrogen In the process of pyrolysis, high-temperature pyrolysis reaction can solve the problem of dioxin emission from ordinary waste incineration. The output of biomass syngas is generated by syngas generator set and integrated into the State Grid, which not only solves the problems of agricultural and forestry waste stacking, environmental pollution, and burning straw without permission, but also makes the agricultural and forestry waste resource utilization converted into electricity and brings economic benefits. In the reactor of downdraft biomass gasifier, when the dioxin produced in the oxidation zone of agricultural and forestry waste, agricultural film, domestic waste and other raw materials passes through the reduction zone of high-temperature carbon layer, because the temperature of reduction zone is between 800-1200 ℃, which is higher than the thermal decomposition temperature of dioxin by 700 ℃, dioxin is thermally decomposed. Therefore, the content of dioxin in biomass syngas is very low, which is lower than the international standard. Our company has carried out dioxin detection in October 2020. The detection method is to use treated domestic waste as raw material to produce syngas, and then burn syngas to detect dioxins in the waste gas after combustion. The average value of China's dioxin emission standard GB18145-2014 is 0.1, and the actual detection result of our company is 0.041, which is lower than the national standard.

The derivatives of biomass gasification power generation are: (1) biochar (2) biomass oil (3) wood vinegar.

Application of biochar

The adsorption of biochar is as follows A. Adsorption of methylene blue in water by biochar prepared from crop residues Biochar was prepared by pyrolysis of rice straw, rice husk, soybean straw and peanut straw at low temperature. The adsorption of methylene blue and the removal of methylene blue from water were studied by equilibrium adsorption and leaching experiments. The results showed that biochar had high adsorption capacity for methylene blue, but there were great differences among different biochars. The order of adsorption capacity of four kinds of biochar was rice straw carbon soybean straw carbon peanut straw carbon rice husk carbon, which was basically consistent with the order of the number of negative charges on the surface of biochar and the specific surface area of biochar. B. Effects of biochar application on the adsorption and degradation of chlorantraniliprole in soil The application of biochar could improve the adsorption activity of cap in soil, but the degree of improvement varied with the soil properties. When biochar was added to the black soil with higher organic matter content, the Kd value of pesticide adsorption increased by 2.17%, while that of the fluvo aquic soil with low organic matter content increased by 139.13%. The results showed that biochar could enhance the adsorption of pesticides and delay the soil degradation of pesticides, but the degree of impact was related to soil properties. C. Environmental benefits of biochar CO2 emission from farmland soil organic carbon mineralization is an important way of agricultural greenhouse gas emissions. Promoting soil carbon capture is of great significance to mitigate the global greenhouse effect. Biochar can improve soil properties, promote the formation of soil aggregates, and regulate soil microbial ecology. Therefore, biochar may play an important role in enhancing soil carbon capture capacity and reducing soil CO2 emissions. At the same time, biochar can also promote the growth of plants. The addition of straw biochar has a good retention function for soil nutrients. Adding biochar can significantly reduce the mass concentration of nitrogen and phosphorus in soil leaching liquid. Biochar can effectively reduce the loss of nitrogen and phosphorus caused by water erosion and reduce agricultural non-point source pollution. D. Returning biochar to field can effectively reduce the content of heavy metals in soil. Biochar has high carbon content, rich in K, Ca, Mg and other ash elements, rich pore structure, large specific surface area, stable physical and chemical properties, alkaline or strong alkaline. From the perspective of agronomic application, biochar can not only increase the organic matter, K, Ca, Mg and other ash elements (especially K element) in the soil, but also improve the soil structure. Its rich pore structure can provide an ideal habitat for microorganisms and promote the activation and proliferation of micro organisms in the soil. At the same time, the strong alkalinity of biochar can improve and improve the acid soil Very significant effect. From the perspective of environmental protection and health, the strong adsorption of biochar can reduce the residues of heavy metals and pesticides in soil, and reduce the risk of heavy metal pollution in food and vegetables.

Application of bio oil

Biomass oil (TAR) is one of the most important products in coking industry. Its output accounts for 3% ~ 4% of the raw materials for furnace charging. Its composition is very complex. In most cases, it is separated and purified by professional industries and then used. Various products can be separated from the fractions of biomass oil (TAR) Naphthalene: used to prepare phthalic anhydride for resin, engineering plastics and dyes. Paint and pharmaceutical industry applications. Phenol: and its homologues to produce synthetic fibers, engineering plastics, pesticides, medicine, fuel intermediates, explosives, etc. Anthracene: Anthraquinone fuel, synthetic kneading agent and paint. Phenanthrene: it is the isomer of anthracene, and its content is second only to naphthalene. It has many uses. Due to its large output, it needs further development and utilization. Carbazole: it is an important raw material of dyes, plastics and pesticides. Asphalt: is the biomass oil (TAR) distillation residue, for a variety of polycyclic polymer compounds mixture. It is used for roof coating, damp proof course and road construction, pitch coke and electric furnace electrode. At present, more than 230 kinds of products have been extracted from biomass oil (TAR) by advanced manufacturers of biomass oil (TAR), and centralized processing is developing towards large-scale.

Application of wood vinegar

Wood vinegar is a by-product of charcoal production. It can also be produced with rice husk, coconut shell, straw and other wastes. It is harmless to human and livestock, and will not pollute the environment. It is an ideal substitute for chemical pesticides. In our country, the traditional process of carbon production, with a little renovation, can extract wood vinegar at the same time of carbon production, with considerable economic benefits. China's traditional agriculture is rich in connotation, which provides abundant raw materials for the production of wood vinegar. The development and utilization of wood vinegar has broad prospects in China. Wood vinegar has been widely used in agricultural production in the United States, Japan, South Korea and other countries. In the United States, wood vinegar is used in garden gardening, forestry and fruit industry. In comparison, wood vinegar is the most widely used in Japan. In Japan, about 50000 tons of wood vinegar is produced annually, about half of which is used in agricultural production, mainly for promoting crop growth and controlling nematodes, pathogens and viruses. The other half is used in food processing, medicine and health care. Japan has developed "forest vinegar" beverage by using wood vinegar. Refined wood vinegar has been used in medicine in South Korea. The application of wood vinegar in Taiwan started earlier, and was widely used in forestry and fruit industry, promoting crop growth and controlling diseases and insect pests. Soil improvement: spraying wood vinegar in soil can prevent seed blight and can also be used as soil disinfectant. Application of bamboo vinegar in soil can effectively inhibit the reproduction of microorganisms that hinder plant growth, and can kill root knot nematodes and other pests. Deodorization: wood vinegar can be used for the deodorization of fresh products such as toilet manure treatment, livestock houses and fish markets. Spraying wood vinegar in the toilet and other places with odor can eliminate the odor and keep the air fresh. Spraying wood vinegar once can last for 3-5 days. Summer can also be used as a perfume to eliminate sweat and other odors on the body, and make people feel cool. Plant growth regulator: wood vinegar can promote the growth of vegetables, fruit trees, flowers, rice, lawn and other plants. In addition, wood vinegar can also be used to make fertilizer, inhibit the growth of weeds, reduce the amount of pesticides, insect repellent and so on. Food preservation: wood vinegar is often used in food industry for its anti mildew, antibacterial and antioxidant properties. Liquid smoked products: ham and sausage soaked in clarified wood vinegar, and then smoked, the ham and sausage are not easy to grow worms and taste more delicious. Beverage additive: the raw liquor of wood vinegar is refined to remove harmful substances such as methanol and formaldehyde, which can be used as health beverage additive. Feed additive: as feed additive, wood vinegar can improve the meat quality of livestock and fish, improve the quality of fish eggs and nutrition. Other products: wood vinegar is generally made of various kinds of miscellaneous wood branches and unused branches cut down from orchards, etc. it is baked in a charcoal kiln to produce smoke, which makes the natural gas condense into liquid. It is of good quality. However, conifers with high resin content, Casuarina equisetifolia and waste furniture containing paint should not be used. The coagulated liquid is crude wood vinegar, which can be used only after refining and removing the bad components. The main component of wood vinegar is vinegar. In addition, there are more than 100 other components, which have good and bad effects. The effect of wood vinegar is similar to that of vinegar, but more than vinegar. The effect is different mainly due to the different kinds of nutrients or natural pesticides added.
