Low-consumption and environment-friendly biochar production equipment

Abstract

The invention relates to low-consumption environment-friendly biochar production equipment, which consists of a pedestal, a carbonization furnace, a gas purification device, a draught fan, an exhaust pipeline, a thermometer, a carbonization chamber support, a combustion chamber fixation bracket and a rotary handle. The carbonization furnace is composed of a carbonization chamber and a combustion chamber. The combustion chamber bottom is fixed on the pedestal through the combustion chamber bracket. The upper part of the carbonization chamber is movably fixed on a cross beam, and the carbonization chamber can turn freely and rotate around the cross beam. A set of gear linkage system is fixed on a steel pipe at the front end of the carbonization chamber support to adjust the inclination angle of the carbonization chamber. The carbonization chamber, the exhaust gas purification device and the draught fan are communicated through the exhaust pipeline. The carbonization chamber is internally provided with several independent pyrolysis chambers. While saving energy and protecting the environment, the equipment provided by the invention also can rapidly and effectively pyrolyze biomass into biochar, and utilizes the combustible gas generated by biomass pyrolysis to heat itself.

Description

technical field [0001] The invention relates to low-consumption and environment-friendly biochar production equipment, which belongs to biomass recycling equipment. Background technique [0002] The annual output of straw in my country's rural areas is about 700 million tons, but the utilization rate of these straws is low, and a large amount of straws are discarded or burned on the spot, causing serious air pollution and a waste of resources. Therefore, how to effectively utilize the continuous straw resources is a topic worth exploring. Among them, turning it into biochar is one of the ways to effectively use straw. Biochar refers to the product formed by pyrolysis of biomass such as straw under high temperature and anoxic conditions. It has rich pore structure, large specific surface area, stable physical and chemical properties, can effectively improve soil, improve soil fertility, increase crop yield, and can also fix carbon dioxide in the environment and reduce green...

Problems solved by technology

[0003] The technology of using straw to produce biochar has been studied in my country, such as: CN103773404A, CN102020999A, CN204550469, CN203379966U, etc. all involve the production technology of biochar, but there are problems in different degrees in these technologies: such as CN103773404A technology needs to use biochar when feeding The material is crushed and made into 5-10cm small pieces, which is inconvenient to operate, time-consuming and energy-consuming; during the cracking process, it is necessary to use a long rod to move the material or supplementary materials to control the oxygen supply, which is prone to incomplete carbonization, raw material entrainment and ashing problems , need to spray water to cool down after charcoal

For example, in the technology of CN204550469, it is also necessary to cut the straw, and the processing material is too single, and the pipeline is easy to be blocked after the tar is separated during the carbonization process.

In the CN203379966U technology, three motors must be passed to realize feeding, cracking and discharging, and the energy consumption is large

These shortcomings will restrict the application of the above technology to a certain extent
