Straw gasifier

Abstract

The invention provides a straw gasifier, and aims to solve the problem that a conventional straw gasifier is poor in combustion efficiency. The straw gasifier comprises a furnace body and a furnace cover, wherein the furnace cover is arranged on the furnace body in a covering manner; the furnace body is internally provided with a furnace grate; an exhaust hole and an ash outlet are formed in the side wall of the furnace body; the furnace grate is sleeved by a gas inlet tube; the gas inlet of the gas inlet tube is formed outside the furnace body; the gas outlet of the gas inlet tube is right aligned to the side wall of the furnace grate; an exhaust tube is arranged inside the furnace body; the lower end of the exhaust tube is right aligned to the furnace grate; a conical feeding hole is formed in the furnace cover in a penetration manner; the upper end of the exhaust tube penetrates through the feeding hole; a gas inlet tube is screwed inside the upper end; a plurality of gas guide holes are formed in the side wall of the exhaust tube in the penetration manner; a blower II is mounted on the furnace cover through a bracket; the upper end of the gas inlet tube extends outside the exhaust tube and is communicated with the air outlet of the blower II; a conical surface matched with the wall of the feeding hole is arranged on the outer wall of the middle part of the exhaust tube; the conical surface can be propped against the wall of the feeding hole and sealing is achieved by rotating the exhaust tube. The straw gasifier has the advantages of being high in combustion efficiency.

Description

technical field [0001] The invention relates to a gasification furnace, in particular to a straw gasification furnace. Background technique [0002] Existing straw gasification furnaces such as a straw gasification furnace disclosed in China Patent Library [Application No.: 201010160140.7; Application Publication No.: CN 101831321A] consist of a furnace cover, a furnace body, a furnace grate and an annular air pipe; Insulation material is filled between the furnace body and the inner wall of the furnace; the middle and lower part of the inner wall of the furnace is processed with a boss, and the annular air pipe is installed in the boss; the furnace grate is placed on the boss; the air intake pipe installed on the annular air pipe Pass through the furnace body to the outside of the straw gasification furnace; the upper part of the furnace body is equipped with a gas outlet, the lower part is opened with an ash removal port, and the furnace cover is placed on the top of the f...

Problems solved by technology

[0004] However, there are two problems in this gasifier: 1. Straw is piled up on the upper side of the grate, and the gas flow is from the lower side of the grate to the upper side of the grate, resulting in poor contact between the gas and the straw. 2. When the grate is used for a long time, more straw ash will be attached to it to prevent the straw ash on the upper side of the grate from being discharged downward, and the straw ash accumulated on the upper side of the grate will Affect the burning of straw, which further affects the burning efficiency of straw
