Embodiment 1

[0021] A processing technology for agricultural and forestry wastes includes the following steps:

[0022] S1. The agricultural and forestry wastes are roughly crushed, then screened and removed, and then the particles with a particle size of 5mm or more are sent to the receiving bin of the second fine crusher by a belt conveyor to be finely crushed and crushed to a particle size of 2mm the following;

[0023] S2. Soak the crushed material with a particle size of less than 2mm in hot water at 60°C for 12 hours, filter it through a plate and frame filter press, and put it into the fermentation tank. Control the temperature of the fermentation tank at 40°C and humidity 50%, and anaerobic fermentation treatment 15h;

[0024] S3. Pour the biomass charcoal powder into the material after the anaerobic fermentation treatment in step S2, stir evenly, isolate the air and continue the fermentation for 10 days, deodorize and dry to obtain the mixture A;

[0025] S4. Put additives, bentonite and...

Abstract

The invention discloses a treatment process of agricultural and forest waste. The process comprises the following steps of S1, performing coarse crushing on agricultural and forest waste; crushing theagricultural and forest waste to the particle diameter being below 2mm; S3, soaking the materials crushed to the state with the particle diameter being smaller than 2mm into hot water being 60 to 70DEG C for 10 to 12h; performing press filtering by a plate-and-frame filter press; putting the materials into a fermentation pool; S3, adding biomass carbon powder into materials subjected to anaerobic fermentation treatment in the step S2; after the uniform stirring, isolating the air for continuous fermentation for 10 to 20 days; performing deodorization and drying to obtain a mixture A; S4, adding additives, bentonite and anti-coking additives into the mixture A; then, performing uniform mixing to obtain a mixture B; ensuring the water content of the mixture B to be within 15 percent; performing extrusion shaping by using an extrusion shaping machine; performing drying to obtain biomass fuel. The agricultural and forest waste is a resource capable of being regenerated and utilized; theraw material resources are rich; the energy source saving is facilitated by using the agricultural and forest waste solid type regeneration clean fuel; the problem of energy source shortage is solved.

Description

Technical field [0001] The invention belongs to the technical field of agricultural and forestry waste treatment, and more specifically, relates to a process for the treatment of agricultural and forestry waste. Background technique [0002] Agriculture and forestry waste is the main type of renewable biomass raw materials and has great potential for solving energy problems. Agricultural and forestry wastes are large amounts of waste generated during the harvesting and processing of agricultural and forestry crops. For example, the straw left in the farmland when the crops are harvested, the rice husk and chaff remaining in the agricultural production process, and the branches and leaves remaining in the forestry production process , Sawdust and leftovers from wood processing, as well as residues discharged from the food processing industry. [0003] Agricultural and forestry waste is an important member of waste, an important biomass resource, and an important renewable resource....
