Background technology
The residents stalk gasifier of Xiao Shouing does not have the tar treatment unit mostly in the market, the infrared burner that utilizes that has burns to handle, some easy tar treatment unit of the employing that has, tar thoroughly can not be handled, peculiar smell produces after causing tar to stop up pipe network, kitchen range, burning, more tar and the water vapor mixture after handling can not be melted down burning, cause the secondary pollution at soil and water source.
Summary of the invention
The invention provides a kind of tar processing of residents stalk gasifier and melt down combustion unit, can solve the combustion problem that melts down that tar stops up to be had peculiar smell to produce after pipe network, kitchen range, the burning and handle back tar and water vapor mixture, make residents stalk gasifier aerogenesis continuously, continuously handle tar and water vapor, form a kind of clean-production system from the body closed cycle.
For reaching above-mentioned target, adopt following technical scheme: a kind of residents gasifying stalk coke oven tar is handled and is melted down combustion unit, the escape pipe of described residents stalk gasifier is connected with the inlet end movable sealing of first step cooling pneumatic tube, the parallel outside back that places cooling water tank and its another port to be in cooling water tank of this first step cooling pneumatic tube seals locking with tightening cover, many first step cooling pneumatic tubes that are in the cooling water tank are interconnected, and the first step cooling pneumatic tube that is in the cooling water tank bottom is communicated with the tar return tank by pipeline; The inlet mouth of the outlet of described first step cooling pneumatic tube and second stage cooling pneumatic tube is communicated with, and this second stage cooling pneumatic tube circumferential play is with the air cooling pipe, and blower fan is communicated with described air cooling pipe top; The top of the outlet of described second stage cooling pneumatic tube and the pipeline of connection tar strainer and tar return tank is communicated with, the top of described tar strainer and the import of induced draft fan are communicated with, the outlet of this induced draft fan places in the tar sludge box, this tar sludge box top is communicated with combustion unit by air duct, and this tar sludge box bottom is communicated with the tar return tank.
Among the present invention: the mixed gas that vapourizing furnace comes out passes through water cooling successively from escape pipe, the cold wind cooling that blower fan produces, behind the strainer, the most of filtration of tar wherein and water vapor is deposited in the tar return tank, with the combustion gas after the above-mentioned purification again by after the further purifying treatment of centrifugal induced draught fan, can directly send into the kitchen range burning, heat up water to reach, cook, the purpose of heating, after tar after the centrifugal settling is still got back in the tar return tank, send into vapourizing furnace and the utilization of gas combustion apparatus internal combustion more respectively, it has not only increased calorific value, improved thermo-efficiency, can not make the outflow of pollutent such as tar cause the secondary pollution at soil and water source yet, be completed into one from the clean-production system of body closed cycle, can promote the improvement of rural environment looks, be vast Rural areas creation of resources saving type, friendly environment society has opened up more wide new way.The present invention is a quantum jump of residents stalk gasifier research, accelerated the gasifying stalk process that engineering applies of registering one's residence.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, a kind of residents gasifying stalk coke oven tar is handled and is melted down combustion unit, the escape pipe 1 of described residents stalk gasifier is connected by the flange movable sealing with the inlet end of first step cooling pneumatic tube 2, these first step cooling pneumatic tube 2 parallel outside back that places cooling water tank 3 and its another port to be in cooling water tank 3 tightening cover 5 sealing lockings, many first step cooling pneumatic tubes 2 that are in the cooling water tank 3 are interconnected, and the first step cooling pneumatic tube 2 that is in cooling water tank 3 bottoms is communicated with tar return tank 18 by pipeline 7, and tar and steam mixture after the first step is filtered are flowed in the tar return tank 18; The outlet of described first step cooling pneumatic tube 2 is by the inlet mouth connection of threeway 6 and second stage cooling pneumatic tube 10, the 3rd general plug shutoff of this threeway 6, when settling more for a long time, take this plug apart and clear up; Described second stage cooling pneumatic tube 10 circumferential plays are with air cooling pipe 9, blower fan 8 is communicated with described air cooling pipe 9 tops, the bottom of this air cooling pipe 9 is communicated with vapourizing furnace by pipeline, the cold wind that blower fan 8 is produced enters the interior participation of vapourizing furnace gasification after cool off mixed gas in the second stage cooling pneumatic tube 10, plays energy-conservation effect; Or this blower fan 8 usefulness water tanks replacement, carry out water-cooled and also can; The outlet of described second stage cooling pneumatic tube 10 is by threeway 25 and be communicated with the top connection of the pipeline 19 of tar strainer 11 and tar return tank 18, the 3rd general plug shutoff of this threeway 25, when settling more for a long time, take this plug apart and clear up; Described tar strainer 11 suitable for reading by tightening cover 12 lock sealings; The import of the top of described tar strainer 11 and induced draft fan 13 is communicated with, the outlet of this induced draft fan 13 places in the tar sludge box 14, these tar sludge box 14 tops are communicated with combustion unit by air duct 15, and these tar sludge box 14 bottoms are communicated with tar return tank 18 by pipeline 16.
Be provided with the porous filtering flap 4 of multilayer in the described first step cooling pneumatic tube 2.Both can reduce the mixed gas flow velocity, can also play cascade filtration, and make filter effect better.
Be first filtering layer 20, active carbon layer 21, second filtering layer 22 from the bottom up successively in the described tar strainer 11.This first, second filtering layer 20,22 filtration order number change from small to big from top to bottom, make filter effect better; And first, second filtering layer 20,22 material can be selected steel filtering net or plastic cement filtering net or make filtering net with sponge all can.
Described tar return tank 18 1 sides are communicated with by pipeline 23 and vapourizing furnace, and opposite side is by pipeline 17 and place the combustion chamber 24 of duration and degree of heating periphery to be communicated with.When the tar position that stores in the tar return tank 18 exceeds the oral area of the pipeline 23 that is communicated with vapourizing furnace and during the oral area of the pipeline 17 that is communicated with described combustion chamber 24, tar in the tar return tank 18 flows in the stove respectively or in the combustion chamber 24, can utilize the tar secondary combustion.Described combustion chamber 24 is annular groove-shaped structures.
The position of the outlet of described induced draft fan 13 in tar sludge box 14 will be lower than the connected entrance of this tar sludge box 14 and described air duct 15.Make tar and moisture from the mixed gas that induced draft fan 13 comes out under action of gravity, directly enter tar return tank 18 by pipeline 16 like this, and gas go up to enter air duct 15 for the combustion unit use, makes result better.
