Heat, electricity and fertilizer coproduction system and process for edible mushroom dreg

Abstract

The invention discloses a heat, electricity and fertilizer coproduction system for edible mushroom dreg. The system comprises a mushroom bag breaker, a sorting machine and a roller drier which are connected in series sequentially, wherein a medium inlet of the roller drier is connected with a hot-blast furnace. The system is characterized in that a material outlet of the roller drier is connected with a rotary discharging bin through a screw feeder and an elevator, a discharging opening of an additive screw conveyor is connected with a charging opening of the screw feeder, the rotary discharging bin is in series connection with a derived fuel pelletizer, a cooler and a gasifier behind sequentially, and an outlet of the gasifier is connected with a fuel gas exhaust-heat boiler through a settlement type purifier and a draught fan. The invention further discloses a heat, electricity and fertilizer coproduction process for the edible mushroom dreg. According to the system and the process, the mushroom dreg can be treated industrially in time, the pollution to environments is prevented, the resource expenditure is low, the value of products is high, continuous production and long-term normal operation are achieved, the comprehensive economic benefit is improved, and the resource utilization of the mushroom dreg can be achieved.

Description

technical field [0001] The invention relates to a thermoelectric fertilizer cogeneration system and process for edible fungus residue. Edible fungus slag heat and electricity fertilizer cogeneration system and process. Background technique [0002] In China's agricultural economy, edible fungi are second only to grain, cotton, oil, vegetables, and fruits, ranking sixth. The fungus bags for cultivating edible fungi include plastic bags and the strains in them, straw powder, peanut shells, corn cobs and Cottonseed shells and other fungal residues are all biomass. At present, fungal residues are piled up randomly in the fields, dumped in riverbanks, ditches, or even burned. The annual amount of fungal residues in Heilongjiang Province alone is as high as more than 1 million tons, which brings great harm to the agricultural environment. Huge pressure has led to extremely serious non-point source pollution in rural areas, continuous deterioration of air quality, and the industry...

[0002] In China's agricultural economy, edible fungi are second only to grain, cotton, oil, vegetables, and fruits, ranking sixth. The fungus bags for cultivating edible fungi include plastic bags and the strains in them, straw powder, peanut shells, corn cobs and Cottonseed shells and other fungal residues are all biomass. At present, fungal residues are piled up randomly in the fields, dumped in riverbanks, ditches, or even burned. The annual amount of fungal residues in Heilongjiang Province alone is as high as more than 1 million tons, which brings great harm to the agricultural environment. Huge pressure has led to extremely serious non-point source pollution in rural areas, continuous deterioration of air quality, and the industry is facing the bottleneck of "more development, more pollution"; since the average water content of fungal residue is higher than 40%, if it is used as a bio-organic fertilizer base material At the same time, a large amount of nitrogen source organic matter is required as ingredients, which limits the large-scale utilization of fungus residues. For example, a large amount of feed material culture medium is also required when fungal residues are used as raw materials for feed. The resource consumption is large, and the corresponding input costs are also high. Comprehensive economic benefits Poor, unable to realize resource utilization of fungus residue
