Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, be that the utility model is exempted to clean gas cutting-off machine embodiment and carried in the course of gas dirty slag to discharge view automatically, this is exempted to clean gas cutting-off machine and comprises cylindrical shell 1, top cover 27, dividing plate 2, intake pipe 3, overflow pipe 4, gas inlet pipe 5 and coal gas steam outlet pipe 6, cylindrical shell 1 top is provided with top cover 27, dividing plate 2 is divided into suction chamber 7 and discharge chamber 8 with cylindrical shell 1 top, the top of dividing plate 2 and both sides pass top cover 27 and cylindrical shell 1 respectively, suction chamber 7 side neck bodies 1 are provided with gas inlet pipe 5, discharge chamber 8 side neck bodies 1 are provided with overflow pipe 4 and coal gas steam outlet pipe 6, overflow pipe 4 outlets are higher than dividing plate 2 lower edges, and gas inlet pipe 5 and 6 outlets of coal gas steam outlet pipe also are higher than dividing plate 2 lower edges.
Cylindrical shell 1 bottom is provided with automatic sweeper 28, and dividing plate 2 lower edges are higher than automatic sweeper 28, and sweeper 28 comprises taper slag bucket 9, drain pipe 10, blowdown valve 17 automatically, and taper slag bucket 9 bottoms are provided with drain pipe 10 and blowdown valve 17 successively.When dividing plate 2 is individual layer solid slab body structure, generally select the anti-corrosion wear-resistance stainless steel material for use, when dividing plate 2 is the MULTILAYER COMPOSITE plate body structure, general core is selected common carbon steel board or corrosion resistant plate for use, outside and medium contact position is corrosion-proof wear ceramic plate, glass epoxy or phenolic resin plate, to improve the corrosion-proof wear performance, make the working life of being longer than cylindrical shell 1 and taper slag bucket 9 working life of dividing plate 2, to guarantee that exempting to clean gas cutting-off machine is perfectly safe reliably in life time.
Drain pipe 10 blows logical high pressure steam or water in the slag pipeline 12 by blowing slag valve 11 and blowing slag pipeline 12 and be connected.Drain pipe 10 joins by the dust flue 19 of blowdown valve 17 with hydathode 18 upper ends.Overflow pipe 4 also links to each other with dust flue 19 by spilling water valve 20.
When carrying coal gas to be coke oven or coke oven mixed gas, discharge smoothly in order to guarantee dirty slag 26, can twine heat tracing measures such as ribbon heater 29, steam tube at the outer wall of cylindrical shell 1 and automatic sweeper taper slag bucket 9, or heating equipments such as electric heating tube 30 are set in taper slag bucket 9 inside.
This exempts to clean gas cutting-off machine in carrying course of gas, gas inlet valve 21, coal gas gas outlet valve 22 are in opening state, simultaneously table valve 1, the table valve 2 24 of pressure gauge 2 14, blowdown valve 17, the spilling water valve 20 of pressure gauge 1 are all opened, and the inlet valve 25 on the intake pipe 3, blow slag valve 11, displacement valve 15 all cuts out.Coal gas is through gas inlet valve 21, gas inlet pipe 5 enters suction chamber 7, the coal gas that enters cylindrical shell 1 flows along the thin direction of arrow among the figure, walk around dividing plate 2 lower edges and enter discharge chamber 8, transfer out through coal gas steam outlet pipe 6 and coal gas gas outlet valve 22 again, during this period, the dirty slag of carrying secretly in the coal gas 26, after meeting dividing plate 2 obstructs, direction drops in the taper slag bucket 9 shown in the thick arrow in the figure of centrifugal action lower edge, through drain pipe 10, blowdown valve 17 and dust flue 19 enter in the hydathode 18 and collect, make in cylindrical shell 1 and the taper slag bucket 9 not contamination slag, thereby it is unblocked that coal gas is carried.
Under extremely special situation, a large amount of dirty slags 26 can stop up the drain pipe 10 of taper slag bucket 9 bottoms, can feed high compressed steam or the water of pressure greater than pressure shown in the pressure gauge 1 this moment by blowing slag valve 11 and blowing slag pipeline 12 in drain pipe 10, dirty slag is washed open, dirty subsequently slag 26 can flow in the hydathode 18 together with sewage, close then and blow slag valve 11, stop to blow slag, the whole slag process of blowing need not be stopped gas delivery.
See Fig. 3, be that the utility model exempts to clean the view that gas cutting-off machine embodiment cuts off the coal gas operation, under the normal state of carrying of coal gas, through intake pipe 3, inlet valve 25 feeds the water of pressure greater than pressure shown in the pressure gauge 1 in cylindrical shell 1, at this moment, water is discharged from hydathode 18, close drain pipe 10 then, water filling in cylindrical shell 1, when water level exported to overflow pipe 4, the drain opening of hydathode 18 began draining, and the hydraulic pressure that height difference produces between overflow pipe 4 outlets and dividing plate 2 lower edges is greater than the gas pressure of suction chamber 7, in suction chamber 7, this moment, finished by the gas cutting operation with the coal gas shutoff for water.
Behind the gas cutting, in cylindrical shell 1, feed the medium of displacement coal gas (as steam, nitrogen N by displacement valve 15 and substitution gas pipe 16
2Deng) with the coal gas in the displacement coal gas steam outlet pipe 6, as long as use the pressure shown in the air chamber pressure table two 14 all the time smaller or equal to the pressure shown in the suction chamber pressure gauge 1.During this period, regulate inlet valve 25, remain overflow pipe 4 and discharge low amounts of water.
After the construction of coal gas associated pipe finishes, close displacement valve 15 and inlet valve 25 successively, open blowdown valve 17, can recover coal gas again and normally carry water emptying in the cylindrical shell 1.
