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 service life 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 household gasifiers. Background technique

[0002] At present, the updraft gasifier in the prior art has a simple structure, low cost, and a wide range of straw resources, and because of the global concern about the energy crisis and the air pollution caused by the seasonal burning of agricultural wastes such as straw, the party And the country attaches great importance to the development and utilization of this renewable energy, encourages and advocates straw energy, and strives to achieve both energy saving and environmental protection. However, due to the high requirement on the dryness of straw in the gasifier in the prior art, and because of the inability to grasp the timing of feeding, the gasifier often removes the material and extinguishes the flame, and the pipeline is blocked due ...

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 certain slope, the upper part is small and the lower part is large; There is an overflow pipe 33, the center of the dehumidification furnace cover 5 is equipped with a slightly thicker guide sleeve 2, which can double as an exhaust pipe, the upper part of which can be set with an exhaust valve 1, and the lower part can be set according to the required height. Prompt 3, the guide sleeve has a built-in thin guide post 8 connected to the pressing block 9, the top of which is embedded with the magnetic block 4, there should be a gap between the guide sleeve and the guide post to facilitate exhaust, and the lower part of the furnace body is connected to refractory castables Furnace 10, the inner bottom of the refractory castable furnace is provided with a combination device of an air inlet distribution chamber 12 and an ash driving an...
