The beneficial effects of the utility model are: water replenishing device is arranged on the horizontal tank spill pipe, and supplementing water does not contact with coal gas, thoroughly eliminates the dissolving of harmful matter in water in toxic gas bubble that moisturizing produces and the coal gas; Inlet tube at horizontal tank is provided with the running state test valve of judging whether it stops up simultaneously.Draining does not produce toxic gas bubble and harmful sewage outside carrying the gas water sealing device overflow, has solved U-shaped piped gas water seal arrangement overflowing water port and has had the safety related technical problems of poisonous gas and the environmental pollution of outer draining.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the horizontal tank of 1-, 2-main feed water pipe, 3-water-adding pipe, the 4-inlet tube, the feedwater of 5-U type is curved, 6-U type pipe, the 7-dust-proof cover, 8-U type duct occlusion liquid level spill pipe, 9-U type pipe is opened the liquid level spill pipe, 10-U type pipe opens and closes fluid level control valve, 11-flow-off, the outer comb of 12-overflow water, the 13-blowdown valve, 14-exports standpipe, gate valve in the 15-import, 16-running state test valve, gate valve under the 17-import.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of U-shaped piped gas water seal arrangement comprises U-shaped pipe 6, connects main feed water pipe 2 on these U-shaped pipe 6 tops, and main feed water pipe 2 has valve and U-shaped feedwater curved 5; Horizontal tank 1 has blowdown valve 13 inlet tubes and outlet standpipe, and inlet tube 4 links with the bottom of U-shaped pipe 6, and upper gate valve 15 and running state test valve 16, lower gate valve 17 are arranged on the inlet tube 4; Its outlet standpipe 14 open tops, and be provided with dust-proof cover 7; Outlet standpipe 14 is from top to lower, and successively with U-shaped duct occlusion liquid level spill pipe 8, water-adding pipe 3 and U-shaped pipe are opened liquid level spill pipe 9 and linked, and U-shaped pipe unlatching liquid level spill pipe 9 is provided with U-shaped pipe and opens and closes liquid level overflow control valve 10; Flow-off 11 and the outer comb 12 of overflow are arranged at U-shaped duct occlusion liquid level spill pipe 8 bottoms.
During U-shaped duct occlusion, its liquid level spill pipe contact height must guarantee to be filled water in the U-shaped pipe, Yi Bian coal gas can not break through U-shaped water seal from altering to another side; Liquid level spill pipe contact height must guarantee that coal gas is unblocked in the U-shaped pipe when U-shaped pipe was opened, and coal gas can not break through the water seal of horizontal tank, causes coal gas to leak from the slime flux mouth of a river.
When reality was used, U-shaped pipe 6 had two kinds of operating conditionss, and namely coal gas is unimpeded and cut off (being full of water in the U-shaped pipe) two kinds of operating conditionss.No matter which kind of operating conditions the U-shaped pipe 6 of coal gas is in, the state that the valve 15 and 17 on horizontal tank 1 inlet tube 4 all is in out, running state test valve 15 and blowdown valve 13 are in the state of pass.
When U-shaped pipe 6 is gas passage, close the water supply valve on the main feed water pipe 2, open water-adding pipe 3 water valves, open U-shaped pipe and open and close fluid level control valve 10, this moment, the state of current was: water-adding pipe 3 → horizontal tank outlet standpipe 14 → U-shaped pipe opens and closes the outer comb 12 of fluid level control valve 10 → flow-off 11 → overflow water.When flow-off 11 has the water overflow, show that 1 li of horizontal tank has been full of water, according to the size of flow-off 11 overflow waters, regulate the aperture of water-feeding valve on the water-adding pipe 3.
When U-shaped pipe 6 transfers partition coal gas state to from the gas passage state, be to fill with water in the U-shaped pipe 6, close U-shaped pipe and open and close fluid level control valve 10 this moment, open the water supply valve on the main feed water pipe 2, the state of current is: the U-shaped curved 5 → U-shaped pipe 6 of main feed water pipe 2 → feedwater → horizontal tank inlet tube 4 → horizontal tank 1 → horizontal tank outlet standpipe 14 tops → outer comb 12 of U-shaped duct occlusion liquid level spill pipe 8 → flow-off 11 → overflow water.When flow-off 11 has the water overflow, show that U-shaped Guan Liyi is full of water, close the water supply valve on the main feed water pipe 2 this moment, according to the size of flow-off 11 overflow waters, regulates the aperture of water-feeding valve on the water-adding pipe 3.
When U-shaped pipe 6 transfers the gas passage state to from cutting off the coal gas state, only need to open U-shaped pipe and open and close fluid level control valve 10.
Therefore in most of the cases, the U-shaped pipe of U-shaped piped gas water seal arrangement all is in the ventilating coal gas running state, stops up horizontal tank in order to prevent the dust in the coal gas, must regularly check, blowdown.Open test valve 16, discovery test valve 16 is given vent to anger, and then shows horizontal tank normal operation, if find test valve 16 water outlets, show that then horizontal tank stops up, need to carry out blowdown: close lower gate valve 15, drive blowdown valve 13, after the drained dirt, close blowdown valve 13, drive test valve 16, the standard-sized sheet water-feeding valve carries out moisturizing; When test valve 16 water outlets, close test valve 16, open lower gate valve 15, turn water-feeding valve down, maintain a small amount of overflow water.No matter which kind of operating conditions U-shaped pipe 6 is in, because supplementing water does not contact the therefore dissolving of harmful matter in water in the toxic gas bubble of thorough elimination moisturizing generation and the coal gas with coal gas.Draining does not produce toxic gas bubble and harmful sewage outside carrying the gas water sealing device overflow, has solved U-shaped piped gas water seal arrangement overflowing water port and has had the safety related technical problems of poisonous gas and the environmental pollution problem of outer draining.
