Technical implementation: In order to solve the above problems, a low-concentration gas safe and efficient conveying device is proposed, which can realize real-time and appropriate emptying of excess gas through the installation of electric regulating valve on the low-concentration gas conveying pipeline, ensuring stable fuel supply for power generation equipment. At the same time, the flame sensor realizes the linkage protection with the automatic explosion suppression device installed in the gas extraction pump station, reduces the resistance along the conveying system, and solves the problem of low-concentration gas conveying system caused by the imbalance between gas supply and demand. Problems that may occur during use: Poor insulation performance: The poor insulation performance of the insulation layer may cause the outer surface temperature to be too high, affecting the insulation effect of the pipeline. Uneven thickness of insulation structure: The uneven thickness of the insulation structure may cause poor insulation effect in some parts, affecting the overall insulation performance. Metal protective shell problem: The uneven surface of the metal protective shell and the shell falling off may affect the protection and insulation effect of the pipeline. Internal condensation: When the temperature is relatively low, condensation water may appear on the surface of the pipeline, i.e. internal condensation. System blockage: The blockage of the insulation pipeline system will cause poor water flow, affecting the heating or cooling effect, which may be caused by the accumulation of insulation material fragments, impurities, etc. in the pipeline. Gas concentration control problem: During gas conveying, if the CH4 concentration is too high, the pneumatic valve on the pipeline will automatically close to prevent entering the methane explosion limit, stopping the introduction of gas into the heat storage oxidation device, and the over-limit gas is discharged through the venting pipeline to ensure safety performance. Equipment failure and accident: Improper insulation may cause equipment failure and accidents, especially in cold seasons, the control of wellhead temperature directly affects the overall operation efficiency and safety level of the mine. To solve these problems, the insulation pipeline needs to be checked regularly, and the problems need to be solved in time. For the seriously damaged parts, the insulation material should be replaced in time, and the pipeline should be thoroughly cleaned and disinfected. At the same time, the maintenance and management of the pipeline system should be strengthened to ensure good water quality and prevent impurities from entering the pipeline to improve energy utilization efficiency and ensure production safety. The high-gas mine ice water insulation pipeline conveying device is a device specially used for conveying gas in coal mines, which has insulation function to ensure the effective control of the temperature of gas in the conveying process.

The role is temperature control: through the heat preservation pipeline transportation device, the temperature of gas can be effectively controlled, especially in cold environment, to prevent gas from affecting its transportation efficiency and safety due to low temperature. Safety guarantee: heat preservation pipeline can reduce the risk of gas leakage, because temperature control helps to prevent condensate from being generated in gas transportation due to large temperature difference, thereby reducing the risk of gas explosion. Efficiency improvement: heat preservation pipeline helps to maintain the efficiency of gas transportation, especially in low temperature environment, which can reduce the problem of decreased gas transportation efficiency due to low temperature. Importance of safe production: high gas mine ice water heat preservation pipeline transportation device is crucial for the safety production of coal mine, which can effectively prevent gas leakage and explosion accidents and protect the life safety of miners. Environmental protection: through effective gas transportation and utilization, the impact of gas emission on the environment can be reduced, promoting the use of clean energy.
