Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model, for the convenience of describing, used some nouns of locality, all be directed against direction shown in the drawings usually like " top ", " bottom ", or be directed against each parts mutual alignment relationship description word of vertical or gravitational direction.
The utility model provides a kind of gas liquor seal apparatus of tamping coke furnace; The working pressure of the gas pipe line of this tamping coke furnace is P, and the water-column that this working pressure P is corresponding is H, and the gas liquor seal apparatus has water seal height h; And said water seal height h is greater than said water-column H.
Usually, the working pressure of the gas pipe line of tamping coke furnace is less than 0.02MPa, because 1MPa=10 kilogram pressure; 1 kilogram of pressure=10 meter water column; Therefore, extrapolate 0.02MPa=2 meter water column=2000 column, promptly the water-column of the working pressure of gas pipe line correspondence is less than 2000 millimeters.And tamping coke furnace is set to when the pressure in the gas pipe line during greater than 0.02MPa, and the gas heating system of tamping coke furnace can stop heating automatically.Therefore, the water seal height h of the gas liquor seal apparatus of the utility model is set to greater than 2000 millimeters, after breaking down suddenly with gas heating system at coke oven, and still can better seal coal gas.
The water seal height h of gas liquor seal apparatus can be for greater than 2000 millimeters arbitrary height, but as a kind of economy and useful embodiment, and water seal height h that can the gas liquor seal apparatus is set to the 2050-2150 millimeter.
Fig. 1 is the structural representation according to the gas liquor seal apparatus of the tamping coke furnace of a kind of mode of execution of the utility model.Of Fig. 1; The gas liquor seal apparatus of this mode of execution comprise have sidewall 11, the cell body 1 of roof 12 and diapire 13, have spill pipe 2 in this cell body 1, the upper end of this spill pipe 2 is the top that flow-off 21 and this flow-off 21 are positioned at said sidewall 11; The water seal height of gas liquor seal apparatus is the height between the lower end of flow-off 21 and spill pipe 2; The h that promptly marks among the figure, as a kind of preferred implementation, water seal height h is set to 2100 millimeters.
In addition; Be provided with drain opening 3 in the bottom of sidewall 11; Roof 12 is provided with admission port 4, diffuses mouth 5 and gas port 6; Drain opening 3, admission port 4, diffuse mouthfuls 5 and be connected with waste pipe 31, supply pipe 41, exhaust stack 51 and gas pipe 61 through flange respectively with gas port 6, wherein, supply pipe 41 and gas pipe 61 extend to the bottom of cell body 1.
This gas liquor sealing groove is placed in the basement of tamping coke furnace bottom; In cell body 1, fill it up with industry water through supply pipe 41; When pipeline overhauls or does the water seal leakage test; In the time of need the water in the cell body 1 being emitted, the water in the cell body 1 is discharged from waste pipe 31, and waste pipe 31 is in closed condition at ordinary times.
When using the gas liquor seal apparatus of the utility model, when the gas heating system of coke oven breaks down, pressure moment of gas pipe line is when increasing to 0.02MPa; Because the water seal height h of this gas liquor seal apparatus is greater than 2000 millimeters, coal gas can earial drainage in a flash at this, and the gas heating system of coke oven can stop heating automatically when pressure increases to 0.02MPa; Thereby manifold pressure can not increased again; Therefore, when the gas heating system of coke oven broke down, the utility model can guarantee that coal gas does not leak; Thereby guarantee coking technique personnel's personal safety, and guarantee the direct motion of coke oven production safety.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned mode of execution; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technological scheme of the utility model, these simple variant all belong to the protection domain of the utility model.In addition; Each concrete technical characteristics described in above-mentioned embodiment under reconcilable situation, can make up through any suitable manner; As long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
