[0003] Existing water-sealed gas control explosion-proof devices usually discharge gas into the explosion-proof device, and the water in the explosion-proof device absorbs a large amount of heat generated by the explosion. When the weather temperature is low, the water may freeze, resulting in the water being unable to continue to play its role of cooling and absorbing heat, thereby affecting the explosion-proof performance of the explosion-proof device. In addition, when the gas is discharged into the explosion-proof device, impurities will be precipitated in the water, which can easily cause corrosion to the internal structure of the explosion-proof device, affecting its service life, which is relatively inconvenient.

[0004] Therefore, it is necessary to design a water-sealed gas control explosion-proof device that can heat water to prevent water from freezing due to low temperature, improve the explosion-proof performance of the explosion-proof device, filter impurities in the water, reduce corrosion to the internal structure of the device, and extend the service life of the device.
