Biochar preparation device with solar heat collection function

Abstract

The invention provides a solar heat collection biochar preparation device, and relates to the field of biochar preparation devices. The solar heat-gathering charcoal preparation device comprises a box body, a box cover, a heat gathering assembly, a heat conduction assembly and a ventilation pipe, the box cover is rotationally connected with the box body and used for closing or opening the top of the box body. The box cover is of a hollow double-layer structure, and light holes are formed in an upper-layer plate of the box cover. The heat collecting assembly is arranged on the upper layer plate of the box cover and used for focusing sunlight to the upper end of the heat conducting assembly through the light transmitting hole; the heat conduction assembly penetrates through the lower layer plate of the box cover and is used for guiding heat energy at the upper end of the heat conduction assembly into the box body; the ventilation pipe is arranged on the box cover in a penetrating manner; a one-way valve is arranged at the end, located in the box body, of the ventilation pipe and used for discharging gas in the box body to the outside. The device can utilize solar energy to prepare the biochar, is simple in structure, and can avoid energy waste caused by burning the biochar by fire or electric power.

Description

technical field [0001] The invention relates to the field of biochar preparation devices, in particular to a biochar preparation device with solar energy concentrating. Background technique [0002] Biochar is a commonly used soil conditioner and is often used in agricultural fertilizers. It is a carbon-rich solid formed by carbonization of biomass under high temperature and anaerobic conditions. Agricultural biomass wastes such as straw and husk are often used as raw materials for production . Because biochar has a loose and porous structure, it helps farm soil to retain water and fertilizer, provide nutrients needed by plants, and promote the contact between roots and air, which can effectively prevent plant root diseases, reduce plant availability of heavy metals in soil, and improve crop growth. There are many benefits and great potential in the field of crop cultivation. The use of biomass waste to produce biochar is also an important way to achieve "carbon neutrality...

AI Technical Summary

Problems solved by technology

On the one hand, the traditional method consumes a lot of energy and electricity, on the other hand, it consumes a lot of transportation costs, and the collection efficiency of agricultural waste is low, and it is impossible to use biomass waste economically and effectively.
