Description
Technical Field
The utility model relates to an farming field, more specifically say, relate to a thermoelectricity fertilizer gas polygeneration low carbon circulation system based on planting and breeding combines.
Background
China is rich in biomass resources, but the clean utilization of biomass cannot be effectively utilized, and the firewood and straw which can be utilized in a direct combustion mode for rural life account for 56.3 percent. Sulfur dioxide, nitrogen dioxide and the like generated by burning straws seriously pollute the air environment and are harmful to human health; and the biomass waste is dumped disorderly, which causes large-area pollution to the water quality. The ministry of agriculture is the first public recognition that agriculture has become the largest non-point source pollution industry in china beyond industry. However, biomass has a significant advantage over other renewable energy sources in that it is the only renewable energy source that can be directly used as a fuel, and is also the only renewable energy source that can be stored and stably utilized. The sewage of the breeding industry contains a large amount of pollutants, and the main pollution indexes are BOD, COD, SS, Escherichia coli, ascarid eggs, nitrogen, phosphorus and the like. The livestock and poultry manure pollutants not only pollute surface water, but also easily permeate into underground water due to toxic and harmful components, and seriously pollute the underground water. The excrement of the farm produces a large amount of foul gas which contains a large amount of ammonia, sulfide, methane and other toxic and harmful components, pollutes the surrounding air and seriously affects the air quality. The biogas engineering takes livestock and poultry manure or biomass waste as raw materials, adopts an anaerobic fermentation process to obtain high-quality energy and treat environmental pollution, and realizes a rural energy engineering technology of agricultural ecological virtuous cycle. The biomass pyrolysis gasification process is a clean and efficient treatment process for biomass wastes, takes the biomass wastes as raw materials and converts the quality and the form of solid biomass through a thermochemical process, and has good raw material adaptability and product diversity. However, the raw material supply is unstable due to the influence of the transportation radius of the raw material and the market price, which is a bottleneck for restricting the large-scale pyrolysis and gasification of biomass.
The planting industry biomass waste is a necessary raw material for biomass pyrolysis and gasification, the livestock and poultry manure is a necessary raw material for biogas engineering, and the planting industry can well consume a large amount of biogas slurry, organic fertilizer and biomass pyrolysis liquid and provide rich feed for the breeding industry. The planting industry, the biomass pyrolysis gasification, the breeding industry and the biogas engineering are closely connected and unified whole, and a low-carbon circulating system with self-sufficient raw materials, no pollution and diversified products is formed. The coupling of the planting industry, the biomass pyrolysis gasification, the breeding industry and the biogas engineering has great significance for developing ecological agriculture and renewable energy sources, improving energy structures, realizing sustainable utilization of agricultural resources, reducing greenhouse gas emission and protecting ecological environment.
At present, the large-scale planting industry uses a large amount of chemical fertilizers to cause the standard exceeding of heavy metals in soil and the damage of granular structures, so that the soil is hardened, the crop yield is reduced, and the quality is reduced; a large amount of biomass waste generated in the planting industry is directly burnt to cause serious air pollution and serious water pollution caused by random stacking, or the biomass waste cannot be cleanly and efficiently utilized due to overlarge transportation radius and poor economical and practical properties. The air pollution, water pollution and soil pollution are caused by improper treatment of livestock and poultry manure and flushing water in the breeding industry, and the livestock and poultry feed contains high additives, so that the livestock and poultry have low resistance and poor resistance to infectious diseases. Although the biogas engineering can well treat the livestock and poultry feces, the generation of a large amount of biogas slurry becomes a bottleneck restricting the large-scale production of biogas. The biomass pyrolysis gasification process is mature, the product market is wide, and the main reason for restricting the scale is the stability of biomass raw material supply and the rationality of the price thereof, and the biomass supply and the price are greatly fluctuated by the market.
