Abstract

The utility model discloses a straw gasification furnace, comprising a furnace body (9), a furnace cover (3), a primary air-fetch pipe (4), an outer furnace shell (6), a water jacket (8), a water inlet (12), a hot water outlet (7), an air-supply pipe (15), an ash chamber (13), furnace legs (16), a secondary air-fetch pipe (1), a furnace bridge (11), an ash outlet (14) and an air-out housing (10).The straw gasification furnace is characterized in that the primary air-fetch pipe is fixed in the furnace body, the lower end of the primary air-fetch pipe runs through the furnace bridge, and the upper end is apart from the furnace cover for a certain distance. The secondary air-fetch pipe is fixed to the upper part of the furnace body, and the upper end of the air-supply pipe is fixedly provided with the air-out housing which is provided with a plurality of air-out holes. The gas is supplied to the lower end of the primary air-fetch pipe, and the tar component in the gas is gasified in thepipe. The straw gasification furnace has the advantages of simple structure, low cost and easy clean, completely achieving the inventive propose of the utility model.

Description

Stalk gasifier

Technical field

The utility model relates to a kind of gas furnace, especially a kind of stalk gasifier.

Background technology

As everyone knows, emerge from the technology that begins to utilize faggot, gasifying stalk to generate combustion gas, the vapourizing furnace listing of existing multiple different structure, but existing updraft type vapourizing furnace ubiquity tar content height, it is many that the downdraft vapourizing furnace exists dust, firepower is little, must burn use defectives such as fines, is unfavorable for vapourizing furnace popularizing and promoting in the rural market.In order to address this problem, ZL200820061851.7 discloses a kind of firewood gasification furnace, it is by body of heater, bell, gas blower, blast pipe, escape pipe, grate, ash output hole, blast pipe is higher than grate in the compositions such as hot water interlayer, its body of heater, and its top is provided with an outlet housing with a plurality of production wells, affixed one first air-supply duct on the furnace body inside wall, there is a gap on first its top of air-supply duct apart from the body of heater top, and grate is passed in its underpart, also is fixed with one on the furnace body wall, the secondary air-supply duct, its import is positioned at the grate below, outlet links to each other with the gas-oil separation tube, and the top of gas-oil separation tube is provided with gas outlet, is connected with the combustion gas escape pipe in its outlet, in this structure, combustion gas produces the back and enters first air-supply duct from upper of furnace body, enters oil-gas separator from the secondary air-supply duct that is positioned at the ash-storing bin position again after coming out from first air-supply duct, and the gas appliance use is defeated by in combustion gas after the gas-oil separation.It preferably resolves the gasification problem of tar, but because many gas-oil separation tubes on the structure cause cost to increase, and uses inconveniently, cleans problems such as difficulty.

The utility model content

The purpose of this utility model is to provide a kind of cost low, easy to use for overcoming the deficiencies in the prior art, cleans to be easy to stalk gasifier.Its technical scheme is: stalk gasifier comprises body of heater, bell, once get tracheae, outer furnace shell, water jacket, water-in, hot water outlet, blast pipe, ash storage chamber, stove pin, secondary gets tracheae, grate, ash output hole, outlet housing, once getting tracheae is fixed in the body of heater, grate is passed in its lower end, last end distance bell has certain distance, secondary is got tracheae and is fixed in upper of furnace body, the blast pipe upper end is fixed with an outlet housing, and outlet housing is provided with a plurality of air outlet openings.

Sealing for convenience, body of heater is provided with sealed cistern with the top of outer furnace shell.

Get tracheae for better blocks dust enters secondary, get tracheae by secondary in the body of heater and be connected with an ash damper.

Change the intravital vent of stove for convenience, can allow vent-pipe feed at the bottom of the body of heater, fix a threaded connector at the bottom of the body of heater, the lower end of part has silk mouthful in the vent-pipe body of heater.

When using the utility model stalk gasifier, earlier fuel such as faggot are invested in the body of heater, light with kindling material, cover bell, start gas blower and make its burning, fuel just produces combustion gas under not clean-burning situation, enter from the lower end import of once getting tracheae, comes out to get tracheae through secondary from the upper end and supplies with the gas appliance use.

From the technical solution of the utility model as can be seen, because combustion gas enters from the lower end of once getting tracheae, the tar ingredients of carrying in the combustion gas is gasified in pipe, and the dust that carries is after once get tracheae upper end and come out, because the volume that upper of furnace body is vacated is bigger, air-flow falls sharply, dust just with the combustion gas natural separation, even also having a spot of dust goes together with combustion gas, also under the barrier effect of ash damper, separate with combustion gas, so, in a disguised form the volume that the body of heater internal upper part is vacated has partly become an oil-gas separator structure, does not just need in addition at body of heater peripheral hardware oil-gas separator, not only simple in structure, cost reduces, and cleaning is also easy, has reached goal of the invention of the present utility model fully.
