An automatic negative pressure continuous water release device for gas drainage pipeline and its use method

Abstract

The invention relates to the field of pipeline water release devices for gas extraction systems, and is an automatic negative pressure continuous water release device for gas extraction pipelines, which includes a water discharge tank and a water storage tank. The water discharge tank and the water storage tank are connected through the water discharge interface of the water storage tank. There is a positive pressure connecting pipe; the bottom of the water discharge tank is provided with a water discharge port, above the water discharge port is a float guide rod, the bottom of the float guide rod is provided with a water discharge sealing rubber ball, the middle part of the float guide rod is provided with a float, and the fixed plate is provided with a vacuum valve body and Positive pressure regulating valve, the valve chamber of the vacuum valve body communicates with the inside of the water discharge tank, the outlet end of the vacuum valve body communicates with the water storage tank, the valve chamber of the positive pressure regulating valve communicates with the atmosphere, and the inlet port of the positive pressure regulating valve Connected with the water tank. The continuous water release device can improve the water discharge efficiency of the automatic negative pressure water release device, and at the same time prevent gas leakage when the pump is stopped. The invention also provides a method for using the automatic negative pressure continuous water release device for the gas extraction pipeline.

Description

technical field [0001] The invention relates to the field of pipeline drainers for gas drainage systems, in particular to an automatic negative pressure continuous drainer for gas drainage pipelines and a use method thereof. Background technique [0002] Gas drainage pipeline automatic negative pressure water release device is an indispensable part of gas drainage pipeline. Due to the large amount of water stored in the drainage pipeline, the accumulated sludge in the pipeline will cause resistance to the gas pipeline and increase the load on the gas drainage pumping station, which will cause excessive loss of the pumping station in the long run and reduce the drainage efficiency. In terms of gas utilization such as gas power generation, the gas concentration is too low, the flammability rate is reduced, and the equipment operation efficiency is low. The existing negative pressure automatic water release device has problems such as indirect water discharge and gas leakage w...

Problems solved by technology

Due to the large amount of water stored in the drainage pipeline, the accumulated sludge in the pipeline will cause resistance to the gas pipeline and increase the load of the gas drainage pumping station, which will cause excessive loss of the pumping station in the long run and reduce the drainage efficiency

In terms of gas utilization such as gas power generation, the gas concentration is too low, the flammability rate is reduced, and the equipment operation efficiency is low

The existing negative pressure automatic water release device has problems such as indirect water discharge and gas leakage when the pipeline stops pumping, resulting in less water discharge, poor water discharge effect and potential safety hazards
