Abstract

The utility model provides a firewood gasify furnace, which is characterized in that the utility model modifies the prior firewood gasify furnaces, adds a cracking room under a combustion chamber and connected with the gas outlet pipe of a gasifying chamber, comprises a purifier on the gas outlet pipe at the descending of the cracking room, and comprises a secondary air intake pipe communicated between a first air intake pipe and a gas supply pipe. The firewood gasify furnace can utilize the residual heat of the combustion chamber to crack tars and water, thereby improving gasified gas quality and reducing the resistance in pipes and the blockages in furnace, and the firewood gasify furnace supplies gas after mixing gasified gas and oxidation air, to obtain complete combustion, eliminate black smoke and reduce the cleaning on domestic appliance.

Description

Firewood gasification furnace

Technical field

The utility model belongs to combustion field, relates to stove and accessory, is specifically related to a kind of firewood gasification furnace.

Background technology

In vast rural area, faggot is because of its fuel value is lower, utilizes inconvenience and the abandoned field, abandons the river course, roadside, causes agricultural waste contamination hazard environment.Someone studies firewood gasification furnace, and purpose is to utilize the faggot resource.

Existing firewood gasification furnace comprises body of heater, holding pad, combustion chamber, vaporizer, smoke exhaust pipe, moisture content, tar separation the gas that clarifier will produce in body of heater are come out, and are discharged into indoor, not only can pollute, and tar can not get effective utilization, wasted the energy; The air intake mode of combustion chamber not only can only an air intake, and air-out dish (fire grate) design is unreasonable, causes burning insufficient, burn easily empty, phenomenons such as burnings partially, make gasify undesirable.

The utility model content

The designer explores and improves the state of the art process investigation and analysis of existing firewood gasification furnace, and purpose is to provide a kind of firewood gasification furnace, can overcome the defective of existing firewood gasification furnace existence preferably.

Technical solution adopted in the utility model is a kind of firewood gasification furnace of design, its structure comprises: body of heater, holding pad, the combustion chamber, vaporizer, smoke exhaust pipe is connected in the below, combustion chamber mutually with the vaporizer escape pipe cracking room is set, clarifier is located on the cracking room escape pipe, is communicated with secondary wind inleting tube between blast pipe and air supply pipe.

In technique scheme, wherein the air-out dish of combustion chamber adopts the angled type supplying air disc, offers outward-dipping exhaust vent on card, offers the helical form exhaust vent on the dish side face; Baffle plate wherein is set in cracking room; In the pipeline section of giving vent to anger of clarifier, baffle plate is set; Discharge outlet at clarifier is provided with tap.

The utility model after existing firewood gasification furnace is improved, has following remarkable advantage owing to take above technical measures:

1), set up cracking room, can utilize the high-temperature residual heat around the combustion chamber, to the tar that produces in the gasification, purify water that the back produced etc. and change into fuel gas by the further cracking of high temperature, improved the gasification quality, reduce pipe resistance and kitchen range to block up;

2), clarifier changes on the escape pipe that is located at the cracking room downstream, reduced cleaning of substances, increased the flammable composition of gasification gas;

3), set up secondary wind inleting tube, can make air feed after gasification gas and the oxygen mix, gas is fully burnt, eliminated free carbon and separated out, accomplish " flameless combustion ", and reduce kitchen range are stopped up and clear up;

4), change the air-out dish into the angled type supplying air disc after, can make faggot wide in the combustion chamber contact, burning is evenly avoided inclined to one side burning, burns empty phenomenon, improves factor of created gase, guarantees that gasification furnace normally moves;

5), at cracking room and baffled in clarifier, prolonged gas and in chamber (device), turned round, the time of staying, improved cleavage rate and cooling and purifying rate;

6), tap is set, can utilize hot water to wash one's hands, wash the dishes, bathing etc. in the discharge outlet of clarifier.

Sample through trial-production, post-installation review, dependable performance, easy to use, welcome and favorable comment by the trier, reached designing requirement.
