Description

TECHNICAL FIELD

[0002] When coal gas is transported in a pipeline, part of the saturated gas and mechanical water will separate out, which will adversely affect the transportation of coal gas, the coal gas pipeline facilities and the use of users. Therefore, the condensed water must be discharged from the pipeline in time. The coal gas drainer is a device specially used for discharging condensed water from the coal gas pipeline. The coal gas drainer is sealed by water seal height, discharges condensed water, effectively prevents coal gas leakage, and prevents the occurrence of serious accidents such as fire, explosion and poisoning. The coal gas water seal is a device that balances the pressure of coal gas by using water level, prevents coal gas leakage through the sealing barrier formed by the water column, and discharges condensed water. When the water seal cannot maintain balance due to factors such as coal gas pressure impact and device failure, coal gas will break through the water layer and leak, which is called breakdown. Coal gas leakage will cause serious accidents such as fire, explosion and poisoning. The existing coal gas drainer on the market will close the valve at the leak-proof device when the water seal is impacted by the coal gas pressure and the coal gas breakdown occurs, so that the entire coal gas drainer stops working and waits for maintenance. This has low working efficiency, increases the work burden of maintenance personnel, and increases the maintenance cost of enterprises. SUMMARY
