The specific embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing:
A kind of oiliness waste gas anti-backfire burner is looked bottle 6, spark arrester 7, tempering inductor 8, air proportioning check valve 9, air proportioning valve 10, blower fan 11, anti-backfire check valve 12, oiliness waste gas valve 13, low pressure weighing apparatus by oil gas inlet 1, one-level oil gas buffering knockout drum 2, oiliness waste line 3, magnetic valve 4, secondary oil gas buffering knockout drum 5, liquid oils and is pressed check valve 14, oiliness waste gas burning nozzle 15, high pressure weighing apparatus to press check valve 17, middle pressure weighing apparatus to press check valve 18 to form.
Described oiliness waste gas burning nozzle 15 its nozzle bodies 19 are reducing tubular bodies, and back-fire relief grid 20 is equipped with in its inside, and its big opening end presses check valve 14 to be connected by flange with the low pressure weighing apparatus on the oiliness waste line 3, and its osculum end is connected with combustion furnace 16 by flange.
In the present embodiment, press on the oiliness waste line 3 of check valve 14 from oil gas inlet 1 to low pressure weighing apparatus, by ring flange one-level oil gas buffering knockout drum 2, spark arrester 7, anti-backfire check valve 12, high pressure weighing apparatus pressure check valve 17 are installed successively, in one-level oil gas buffering knockout drum 2 tops also are provided with, press weighing apparatus to press check valve 18.
In the present embodiment, to the oil-gas pipeline of spark arrester 7, by ring flange magnetic valve 4, secondary oil gas buffering knockout drum 5 are installed successively, also are provided with liquid oils in secondary oil gas buffering knockout drum 5 bottoms and look bottle 6 from one-level oil gas buffering knockout drum 2.
In the present embodiment, on the oiliness waste line 3 from spark arrester 7 to anti-backfire check valve 12, by ring flange tempering inductor 8, air proportioning check valve 9, air proportioning valve 10, blower fan 11 are installed successively.
In the present embodiment, on the oil-gas pipeline 3 between anti-backfire check valve 12 and the low pressure weighing apparatus pressure check valve 14 oil gas shutoff valve 13 is housed.
Adopt the combustion furnace 16 of this burner, can on the basis of fire coal, fuel oil, combustion gas and boilers heated electrically, be transformed and to use.
The operation principle division of critical piece is as follows in this burner:
Oil gas burner noz(zle) 15: the oiliness waste gas in the said system by changing thin mouthful of combustion chamber of holding high speed to spray into combustion furnace of diameter, is realized preventing the purpose of tempering with this; In dress less than the back-fire relief critical pore, greater than the back-fire relief grid 20 of back-fire relief critical length, realize purpose that flame is isolated with this.
Oil gas buffering knockout drum 2,5:, reduce the oil gas velocity of liquid assets to realize oil, gas separation function by increasing the oil gas circulation area.
Spark arrester 7: by less than the back-fire relief critical pore, realize the back-fire relief function greater than conditions such as grid, the air-flow of back-fire relief critical length cool.
Tempering inductor 8: information such as the light by surveying identification tempering feature, temperature, pressure is also sent the signal of telecommunication, closes the solenoid valve shuts source of the gas.
Low pressure, middle pressure, high pressure weighing apparatus are pressed check valve 14,18,17: be on the basis of check valve, increased opening pressure resistance measure separately, be implemented under the pressure of expection setting with this, open discharging.
The operation principle of this burner:
Oil gas enters one-level oil gas buffering knockout drum 2 by oil gas inlet 1 and carries out separating of oil and gas, enter again by oiliness waste line 3 and magnetic valve 4 that secondary oil gas buffering knockout drum 5 carries out oil, gas separates again, looking bottle 6 as liquid oils has liquid oils to occur, oil content excessive concentration in the oil gas is described, require the oil gas burn-out at this, reduce the separation function of oil gas temperature and raising one-level oil gas buffering knockout drum 2 through further condensation, no liquid oil occurs in liquid oils is looked bottle 6, and the combustion furnace 16 of being allowed for access carries out normal combustion.
Pure oiliness waste gas is discharged through spark arrester 7, tempering inductor 8 by the outlet of secondary oil gas buffering knockout drum 5 and is entered blower fan 11.
According to the oiliness waste gas tolerance that enters blower fan 11, manually or automatically open air proportioning valve 10 in right amount, air enters blower fan 11 through air proportioning valve 10, air proportioning check valve 9, realizes supplemental oxygen with this, provides condition for oiliness waste gas fully burns.
Press check valve 14 by oiliness waste gas burning nozzle 15 to spray into combustion furnace 16 by the outlet discharge of blower fan 11 through anti-backfire check valve 12, oiliness waste gas valve 13, low pressure weighing apparatus through the oiliness waste gas of air proportioning and carry out abundant work by combustion.
Can stop the oiliness waste gas burning by closing oil gas shutoff valve 13, press weighing apparatus to press check valve 18 under the effect of oiliness waste gas air pressure in this moment, can open automatically oiliness waste gas is discharged into the external world.
If produce the tempering deflagration phenomenon:
Under the state of tempering detonation, anti-backfire check valve 12 lower ends certainly lead to expanding gas, and under the effect of expanding gas, anti-backfire check valve 12 can be closed automatically, and the high pressure weighing apparatus presses check valve 17 to open automatically, and detonation gas is discharged into the external world.
Under the state of tempering detonation, when above-mentioned functions lost efficacy, phenomenons such as the light that tempering detonation gas is sent, heat, air pressure can be surveyed identification by tempering inductor 8, and send the signal of telecommunication by tempering inductor 8, closed magnetic valve 4 and cut off source of the gas.
Under the state of tempering detonation, when above-mentioned functions lost efficacy, spark arrester 7 can be with the front end of burning things which may cause a fire disaster blocking-up at spark arrester 7.
In this device, also can or use some grades of oil gas buffering knockout drums according to the oil content concentration of oil gas.
