A crop straw gasification furnace

Abstract

The invention belongs to the field of civil vaporization furnaces, and particularly relates to a crop straw vaporization furnace. The crop straw vaporization furnace comprises a furnace body, a firstsealing cover, a handle, a fan, a placing plate and a vent pipe; the furnace body is cylindrical, the central axis of the furnace body is vertically placed, and an air inlet is formed in the side wallof the furnace body; the first sealing cover is of a disc-shaped structure with a flange at the bottom, and the first sealing cover is horizontally placed at top of the first sealing cover; the handle is connected to the center of the top of the first sealing cover; the fan is installed on the placing plate which is horizontally connected to the outer part of the side wall of the furnace body, and the fan is connected to an air inlet in the side wall of the furnace body through the vent pipe; and the vaporization furnace further comprises a combustion module, and the combustion module is usedfor burning straws entering the furnace body. During operation, the first sealing cover is lifted, the straws are placed into the combustion module in the furnace body to be ignited, then the first sealing cover is covered, the fan is opened, and the air is conveyed into the interior of the furnace body through the vent pipe and the air inlet, and the combustion process inside the furnace body ispromoted and controlled.

Description

technical field [0001] The invention belongs to the field of civil gasification furnaces, in particular to a crop straw gasification furnace. Background technique [0002] Fire is essential in people's daily life, mainly for heating water, cooking food, raising indoor temperature, etc. In the prior art, natural gas is mostly used as fuel in the city, and because rural areas can obtain materials on the spot, so there are quite large families in rural areas to use firewood as fuel. A large amount of crop straw is produced in rural areas of our country every year, some of which are returned to the field and left in the field after crushing, and some of them are used as fuel, but most of them are discarded and burned directly in the field as the base fertilizer for the next year. Afterwards, a large amount of dense smoke and coke are produced, polluting the atmosphere and the surrounding environment. To solve this problem, people have developed a gasifier. The gasifier is a kin...

Problems solved by technology

[0004] In the above-mentioned patent documents, by setting the first furnace for obtaining combustible gas and the second furnace for combustible gas combustion, and then passing air through the first air pipe and the second air pipe respectively, combustible gas is generated during fuel combustion. The gasification furnace can effectively reduce the amount of particulate impurities in the flue gas flowing to the combustion port, and can recycle the combustible gas, but the structure of the first furnace and the second furnace in the device is complicated, and the It is also necessary to set up a flue gas pipe for the circulation of combustible gas, and the installation cost is high
