Dual-purpose gasification furnace for straw and coal

Abstract

The invention provides a dual-purpose gasification furnace for straw and coal, which pertains to gas production equipment and comprises a furnace body, an emptying valve, an upper hearth, a lower hearth and gas filtering chambers; the upper part of the furnace body is connected with a gas exit pipe which is connected with a first gas filtering chamber, a second gas filtering chamber and a furnace end valve in a serial manner and connected with a furnace end; the lower part of the furnace body is provided with the upper hearth and the lower hearth; an ash collecting chamber is arranged between the upper hearth and the lower hearth; the middle of the upper hearth is provided with an ash leaking hole; the middle of the ash leaking hole is provided with a wind dispersing cover; the lower end of the wind dispersing cover is welded with the lower hearth; the right end of a wind inlet pipe penetrates from the bottom of the furnace body and extends to the inner upper end of the wind dispersing cover, while the left end of the wind inlet pipe is connected with wind outlets of a wind control valve and a fan. Compared with the prior art, the dual-purpose gasification furnace for straw and coal is characterized by convenient installation, energy conservation, high efficiency, health, environmental protection and the like, and has low use cost.

Description

technical field [0001] The invention relates to the technical field of gas manufacturing equipment, in particular to a dual-purpose gasifier for straw and coal. Background technique [0002] At present, the vast rural areas in northern my country use coal stoves for cooking and cooking, heating water and heating, or directly use stoves, which will cause relatively large smoke and dust, and consume a lot of energy such as coal, and emit a lot of smoke and dust, which not only pollutes the environment, but also threatens the environment. Users are in good health, and the energy utilization rate is not high; some use liquefied petroleum gas, but liquefied petroleum gas is dangerous due to certain pressure, and it is expensive, so it is not suitable for popularization. There are a lot of waste straws in rural fields, and these waste straws are gasified As a fuel, it can be suitable for cooking, hot water heating, and will not pollute the environment, and the cost is low.
