Biomass fertilizer preparation process

Abstract

The invention belongs to the technical field of soil fertilizers, and particularly relates to a biomass fertilizer preparation process. According to the biomass fertilizer preparation process, straw is dried and cut so that the combustion efficiency can be improved, the straw is combusted sufficiently through the combustion of a straw biomass boiler, then plant ash does not contain straw residues,the plant ash is effectively prevented from being lost through sealing and packing of the plant ash. The applied straw biomass boiler comprises a frame body and a controller, a rotating shaft of a first motor penetrates into the frame body and is fixedly connected with a stirring unit, a crushing unit is arranged on the inner wall of the top of the frame body, transmission units are arranged in transmission grooves, the sides, close to the inner wall of the frame body, of the transmission grooves are provided with ignition units which are uniformly arranged, a filter plate is made of long-wire ultra-light aluminum silicate materials, and a rotating unit is arranged below the filter plate. According to the process, the combustion efficiency of the straw is high, the produced plant ash doesnot contain the straw residues, and then the plant ash can return to a field for reusing.

Description

technical field [0001] The invention belongs to the technical field of soil fertilizers, in particular to a production process of biomass fertilizers. Background technique [0002] Plant ash fertilizer is the ashes of plants after burning, so it is the mineral elements contained in all plants, almost all of which are contained in plant ash. Straw is the general term for the stems and leaves of mature crops, usually referring to wheat, rice, corn, potatoes, rapeseed, The remaining part of cotton, sugarcane and other crops after harvesting seeds, more than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc., is a multi-purpose Renewable biological resources. Straw is a roughage and also a renewable fuel. The burning of straw can release a lot of heat, which can be used for power generation, cooking, etc. After burning straw, a large amount of plant ash can be used as high-qua...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, solve the problem that the straw is easily covered by plant ash during the burning process, causing some straws to be unable to burn, and the combustion rate is low. Unable to use, lead to waste of energy, plant ash produced by straw burning is easy to block the air hole, resulting in insufficient oxygen in the burner and straw residue in the plant ash after straw burning, which is not conducive to the problem of returning to the field for reuse. material fertilizer production process
