Self-balancing water-seal-type anti-explosion device

Abstract

The invention discloses a self-balancing water-seal-type anti-explosion device which consists of a water seal device, a steam-water separation explosion venting device and an intelligent water level monitoring device, wherein a water seal device cylinder body is internally provided with a primary divergent speed reduction device connected with an air inlet pipeline and a secondary divergent speed reduction device connected with an air outlet pipeline; the air outlet pipeline of the water seal device cylinder body is connected with the steam-water separation explosion venting device; the steam-water separation explosion venting device comprises a tank body, an air inlet, an air outlet, a water discharge adapter tube, a pressure relieving device and a separation device arranged in the tank body; an air outlet pipeline of the water seal device is connected with the air inlet; and the water discharge adapter tube is arranged at the bottom of the tank body, and is communicated with the water seal device cylinder body. According to the invention, the automatic monitoring and automatic supplying of a water seal surface are achieved through combining the cycling of steam and water and the time-to-time monitoring of the water level, thus the water seal surface is kept to be constant, and water is prevented from entering a pumping and extracting system, and pipelines are prevented from being blocked so as to guarantee the safe running of the whole system.

Description

【Technical field】 [0001] The invention relates to a safety device in a coal mine gas drainage system, in particular to a self-balancing water-sealed explosion-proof device. 【Background technique】 [0002] Gas is one of the major hidden dangers of coal mine safety. In order to ensure the personal safety of mine personnel and the smooth mining of coal mines, the gas must be discharged out of the mine in time. The traditional method is to directly discharge the gas out of the mine through exhaust. The gas method has the disadvantages of polluting the environment and wasting energy, but the gas drainage method that has emerged in recent years can better solve the above problems. The method of gas extraction generally refers to extracting gas through a gas pump or other extraction equipment, and water-sealed explosion-proof devices are installed on the pipelines of the intake and exhaust ends of the extraction equipment. When the gas is extracted, the gas passes through the inlet...

Problems solved by technology

The structure of the existing water-sealed explosion-proof devices in my country's gas drainage system is unreasonable, which has caused very serious safety hazards to the safe operation of the entire drainage system. This is mainly manifested in the following aspects: 1. The water supply in the water-sealed device The method is mostly to use manual time-sharing on-site observation to determine the water supply, but the gas flow in the pipeline of the drainage system is very large, and the water in the water sealer is quickly drained, resulting in the loss of the water cover, and the system is in a water shortage The running state brings great hidden dangers to safety; 2. If water is replenished at any time, the water will be pumped into the pipeline, forming accumulations in the low-lying places of the drainage system pipeline, blocking the pipeline, increasing the resistance of the entire system, and reducing drainage The efficiency of the pump; 3. Without intelligent water level monitoring, it can only be observed by manual time-sharing, which is time-consuming and labor-intensive, and cannot realize real-time monitoring
