Device for preparing combustible gas from plant material at high temperature

Abstract

The invention discloses a device for preparing a combustible gas from a plant material at a high temperature. The device comprises a furnace body, a material inlet and a combustible gas outlet at the upper part of the furnace body and a waste outlet at the lower part, wherein a microwave heating device is connected on the furnace body. The microwave heating device is connected on the furnace body, and the interior of the furnace body can quickly reach a temperature required for plant material cracking gasification by heating of the microwave heating device, so the gasification time of the plant material is short, the cracking is complete, the gas yield is high, the temperature is easily controlled and the use is safe and reliable. A stirring device is arranged on the furnace body, and the stirring device does not produce interference to the microwave in the furnace body by asynchronous work of the stirring device and the microwave heating device, so the furnace body has better heating effect and safer use, and the gasification time of the plant material is shorter. The device also has the advantages of reasonable design, good sealing property, easy control and the like, and is particularly suitable for preparing the combustible gas by cracking gasification of plant straws.

Description

technical field [0001] The invention relates to a device for processing and converting combustible gas using plants as raw materials, in particular to a device suitable for high-temperature preparation of combustible gas from plant materials such as straws. Background technique [0002] At present, in order to solve the problem of energy shortage and realize the reuse of plant materials, some technologies and devices for producing combustible gas by using plants as raw materials for heating have been proposed. For example, the Chinese application whose application number is 00111886.2 discloses a "device for producing combustible gas by catalytic cracking of plant material", which is provided with an annular electric heating plate on the inner wall of the furnace body. However, due to the influence of the material and heating principle of the electric heating plate itself, the heating speed is slow through the electric heating plate, and the heating temperature is difficult ...

AI Technical Summary

Problems solved by technology

However, due to the influence of the material and heating principle of the electric heating plate itself, the heating speed is slow through the electric heating plate, and the heating temperature is difficult to control, which is likely to cause incomplete catalytic cracking of plant materials, low gas production rate, and the need to set up an area A larger electric heating plate can achieve a better heating effect, but this is not conducive to the disassembly and replacement of the electric heating plate, and the power consumption is also large, and after the device is used for a period of time, the surface of the electric heating plate will Residues of plants remain, resulting in slower heating of the electric heating plate, uneven heating, seriously affecting the catalytic cracking of plant materials, lower gas production rate, and the device has a heating dead angle, which makes the heating of plant materials incomplete
