A device for producing gas from wood chips

Abstract

The invention discloses a device for producing coal gas with sawdust. The device comprises a cylindrical container with an opening at the upper part, and a container cover, wherein an annular apron board is arranged on the inner side of the opening of the cylindrical container; an annular gas collection cavity with the upper part sealed and the lower part opened is formed by the annular apron board and an inner wall of a housing of the cylindrical container; a coal gas output pipe penetrating through the housing at the side part of the cylindrical container is arranged at the upper part of the annular gas collection cavity; a combustion zone is arranged at the inner lower part of the cylindrical container; an ash discharge hole capable of being opened and closed is formed in the housing at the side part close to the bottom of the cylindrical container; a plurality of air inlet holes or parallel air inlet grooves are formed in the housing at the bottom of the cylindrical container; the container cover can seal and cover the opening at the upper part of the cylindrical container; and a part between the container cover and the opening of the cylindrical container is sealed by a high-temperature-resistant sealing material or an annular water seal tank. The coal gas produced by the device can be delivered over a long distance, and the device solves the energy problems of many regions generating the sawdust and bamboo dust.

Description

technical field [0001] The invention relates to the field of gas production, in particular to a device for producing gas from wood chips. Background technique [0002] The comprehensive utilization rate of wood is an important symbol to measure the level of a country's forestry industry. my country's annual logging of more than 50 million cubic meters of wood, of which about 40% is processed, and about 10% of the wood is turned into sawdust. Therefore my country's annual production of sawdust is equivalent to about 2 million cubic meters of wood, but most of it has not been utilized. Sawdust can be used in many ways, such as board-making raw materials, paper-making raw materials, soil improver, cultivation of edible fungi, livestock dressing and compost, production of activated carbon, production of alcohol, extraction of fuel oil, treatment of industrial waste water, etc., and can also be used to make molded products , the production of sawdust plastic products, the product...

Problems solved by technology

Furthermore, the use of wood chip stoves to directly burn to obtain heat energy results in high air pollution and low heat conversion rate, resulting in great waste

[0004] Many bamboo processing industries also produce a large amount of bamboo chips, and the comprehensive utilization of bamboo chips is not as extensive as wood chips. They are generally burned as fuel, and the result is the same pollution and waste as wood chips.
