Abstract
The utility model relates to the field of metallurgic coal gas recovery, in particular to a device for sealing a high-pressure coal gas pipeline and discloses a device for draining and sealing a high-pressure coal gas pipeline. The device comprises a U-shaped coal gas pipe, a primary water seal tank and a secondary water seal tank, wherein the primary water seal tank and the secondary water seal tank are serially connected below the U-shaped coal gas pipe; the U-shaped bottom of the U-shaped coal gas pipe is communicated with the primary water seal tank through a down pipe; the primary water seal tank is communicated with a secondary down pipe through an overflow pipe; the secondary water tank pipe is communicated with a drainage pipe; a sealing tank is serially connected to the lower part of the down pipe; and a normally-opened sealing baffle is arranged at an outlet of the sealing tank through an elastic resetting mechanism. According to the device, the sealing tank which prevents the high-pressure coal gas pipeline from being punctured is serially connected to the down pipe, and a normally-closed safety valve is arranged on the drainage pipe, so that coal gas leakage due to low level of water in the water seal tank and an accident that the coal gas pipeline is punctured due to pipe network pressure fluctuation can be effectively avoided; and the device can be popularized and applied to other gas conveying pipelines.
Description
Technical field
The utility model relates to metallurgical gases and reclaims the field, relates in particular to a kind of high pressure gas pipeline sealing device.
Background technique
At metallurgy industry, when major product is produced in blast furnace, coke oven and converter, have by-product gas and occur, be respectively blast furnace gas, coke-stove gas and coal gas of converter.These coal gas that produce enter gas cabinet by recovery, again by the pressuring machine force feed to user's use that acts as a fuel.In the process of carrying, along with the decline of temperature, the coal gas of relative saturation can constantly have elutriation to go out, and for the condensed water discharge pipe road of separating out in the coal gas, is provided with some gas pipe line drainage seal tanks on the way at gas pipe line.In order to prevent that coal gas from running out of from gas pipe line, the water level in the drainage seal tank must guarantee certain sealing height; But the water level of drainage seal tank may be former thereby can't guarantee because leak evaporation etc., so the personnel that patrol and examine need regularly to find the low in time moisturizing of water level along the water level of pipe inspection drainage seal tank.
Because coal gas belongs to inflammable gas, requirement of explosion proof is high, and on-the-spot point more than long lines is wide, and work mostly in the open, consider the reasons such as electrical wiring and maintenance, drainage seal tank does not adopt electric controling mode substantially, is that machinery type is utilized connecting vessels " water seal " principle and arranged purely.So can only rely on fully at present and manually remove to check water level, because the needs that save production cost, personnel constantly simplify, equipment is more and more, and the dynamics of patrolling and examining can't satisfy safety requirement, so that occur possibly because of the chronic evaporation of water, in time moisturizing or coal gas do not puncture, not in time moisturizing, the water level that causes reduces, and finally causes gas leakage.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high pressure gas pipeline drainage sealing device, by be in series with the sealed case that prevents that high pressure gas from puncturing at sink drain, effectively prevents the coal gas breakdown accident that the fluctuation of gas leakage and ductwork pressure causes.
The utility model is achieved in that a kind of high pressure gas pipeline drainage sealing device, comprise coal gas U-shaped pipe, one-level flashback tank and secondary flashback tank, described one-level flashback tank and the series connection of secondary flashback tank are arranged on the below of coal gas U-shaped pipe, the U-shaped bottom of described coal gas U-shaped pipe is connected with the one-level flashback tank by sink drain, be communicated with one-level filler pipe and one-level water sealing (sealing water) pipe on the one-level flashback tank, be communicated with the secondary filler pipe on the described secondary flashback tank, secondary water sealing (sealing water) pipe and time sink drain, be connected by spill pipe between described one-level water sealing (sealing water) pipe and time sink drain, described secondary water sealing (sealing water) pipe is connected with waste pipe, be in series with a sealed case under the described sink drain, the outlet port of sealed case is equipped with sealing baffle by flexible restoring organ, and sealing baffle often is arranged.
Described flexible restoring organ is spring.
Directly be in series with normally closed safety valve on the described waste pipe.
The utility model high pressure gas pipeline drainage sealing device is in series with the sealed case that prevents that high pressure gas from puncturing at sink drain, be connected with sealing baffle by spring and prevent the high pressure gas puncture water seal arrangement that fluctuates suddenly, and by normally closed safety valve is set at waste pipe, effectively prevent the coal gas breakdown accident that the low gas leakage that causes of water seal water level and ductwork pressure fluctuation cause.The utility model simple possible, can keep that certain water seal water level is arranged in the drainage sealing device, can guarantee that again normal coal gas uses, can not cause the leakage of coal gas, bring potential safety hazard, cost is low, do not increase any operating cost, easy to maintenance, safe and reliable, can be applied in other gas transport pipelines.
