Intelligent straw gasification furnace

Abstract

The invention relates to an intelligent straw gasification furnace, in particular to an updraft-type household gasification furnace for converting agricultural waste into combustible gas by a limiting-oxygen combustion pyrolytic reaction. A stripping detection alarm and dehumidifying furnace cover system is arranged to increase the density of fuel in the furnace, improve the gas-generating effect,automatically give feeding alarm without stripping material and shutting down, and has no requirements on straw moisture; a porous gas-guiding device is arranged to obtain gas which occupies 80 percent of the total amount and does not contain tar and moisture; the intelligent straw gasification furnace is also provided with an external dredging purifier for convenient dismounting, dredging or replacement; and an automatic anti-blowoff intake system is arranged to ensure full uniform combustion, avoid deflected and suspended combustion in a hearth, and timely crack coke about to form, surely and continuously generate gas and achieve continuous combustion effect. Aiming to overcome the defects that the prior gasification furnace adopting a common steel plate to manufacture the hearth is easy to oxidize and strip to cause perforation in a long-term high-temperature combustion environment, the invention adopts a fireproof casting material to manufacture the hearth and prolongs the servicelife of the gasification furnace.

Description

Technical field

[0001] The invention relates to a gasifier for converting agricultural waste into combustible gas through oxygen-limited combustion pyrolysis reaction. Especially updraft domestic gasifiers. Background technique

[0002] At present, the updraft gasifier in the prior art is simple in structure, low in cost, and has a wide range of straw resources, and because of the global concern about the energy crisis and the air pollution caused by seasonal burning of straw and other agricultural waste, the party The country and the country attach great importance to the development and utilization of this renewable energy, encourage and advocate straw energy, and strive to achieve both energy saving and environmental protection. However, due to the high requirements on the dryness of the straw in the gasifier in the prior art, the material is often removed and the flame is turned off due to the inability to grasp the timing of feeding during use, and the tar is not handl...

Examples

Embodiment Construction

[0013] exist figure 1 Among them, the upper part of the cylindrical furnace body (7) is provided with a conical dehumidification furnace cover (5) with a small upper part and a larger lower part with a certain slope, and its bottom periphery is inserted into an annular water tank (6) arranged around the furnace mouth. An overflow pipe (33) is installed on one side of the annular water tank, and a slightly thicker guide sleeve (2) is arranged upwards in the center of the humidity exhaust furnace cover (5), which can also be used as an exhaust pipe, and an exhaust valve (1) can be arranged on the upper part The lower part can fix the prompter (3) of the built-in magnetic field control switch according to the height set as required, and the guide sleeve is built with a thinner guide post (8) connected to the pressing block (9), and its top is embedded with the magnetic block (4). There should be a gap between the guide sleeve and the guide column to facilitate exhaust. The lower ...
