Embodiment Construction

[0014] The present invention will be further described below:

[0015] The present invention comprises the following steps:

[0016] (1) By weight, take 20% of rice straw, 10% of rapeseed straw, 40% of bamboo, 20% of sawdust and 10% of weeds;

[0017] (2) Pulverizing rice stalks, rape stalks, sawdust and weeds;

[0018] (3) bamboo joints are segmented and broken into strips;

[0019] (4) adding hydrochloric acid solution in the material of step (2) is stirred, mixes;

[0020] (5) Pour the mixture of step (4) into the mould, insert it into the mould, place the mold in a stove and heat it up to 700-900 degrees Celsius, and keep it warm for 1 hour;

[0021] (6) After cooling the product of step (5), put it into a compressor for pressing, and obtain biochar after compacting.

Abstract

The invention discloses a biochar processing method. The biochar processing method includes: according to weight ratio, taking rice straws, rape straws, bamboo joints, saw dust and weeds; smashing the rice straws, rape straws, saw dust and weeds; sectioning the bamboo joints and breaking the same into strips; stirring the mixture by adding hydrochloric acid and evenly stirring the same; pouring the mixture into a mould in an inserting manner, placing the mould in a stove and sealing and heating the same to 700-900DEG C, and keeping warm for 1 hour; after cooling, putting the mixture into a compressor for compression and obtaining biochar after tight compression. Compared with the prior art, the biochar processing method has the advantages that the biochar is made from various kinds of waste straws and is tightly compressed through compression, combustion time of the biochar is increased, storage volume of the biochar is reduced, convenience in use is achieved, and value in popularization and application is realized.

Description

technical field [0001] The invention relates to a kind of biochar, in particular to a method for processing biochar. Background technique [0002] Biochar is a solid product produced by high temperature pyrolysis of biological organic materials (biomass) in an anoxic or anaerobic environment. It can be used not only as a high-quality energy source and soil improver, but also as a reducing agent, fertilizer slow-release carrier and carbon dioxide sequestration agent. It has been widely used in carbon sequestration and emission reduction, water purification, heavy metal adsorption and soil improvement. Provide solutions to hot issues of global concern such as climate change, environmental pollution and soil functional degradation. In the prior art, the combustion time of biochar is short and the combustion efficiency is low, so there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide a biochar processing method in ...
