Description

TECHNICAL FIELD

[0001] The application relates to the technical field of water vapor separation, in particular to a mine-used water vapor separation device with overpressure protection. BACKGROUND

[0002] With the advent of the intelligent era of coal mines, the types and quantities of mine-used equipment are increasing, and these equipment plays an important role in underground operation. Among these equipment, the water vapor separation device is crucial to the normal operation of the equipment and the safety of miners. The existing water vapor separation technology is mainly divided into baffle type, cyclone type and adsorption type.

[0003] According to the search, the patent document with the existing publication number CN218740774U provides a novel water vapor separator. The device is provided with a water vapor separation chamber and a liquid collection chamber, and the former is located directly above the latter. The cyclone separator disc and the baffle are arranged above and below in the water vapor separation chamber. The cyclone separator disc separates large liquid particles, and the baffle separates small liquid particles. The gas passes through the liquid collection chamber and is discharged upward through the gas outlet. The liquid is collected at the bottom of the liquid collection chamber and is discharged downward through the liquid discharge port. This avoids the gas flow from the separation process from wrapping liquid particles, thereby improving the water vapor separation effect.

[0004] Although the above-mentioned device can increase the water vapor separation effect, the pressure of the air compressor has a certain pressure fluctuation. In order to ensure the stability of the air used by a large number of underground equipment and the continuity of the production of the mine enterprise, it is necessary to make the pressure fluctuation range of the input pressure air safe and reliable. The pressure fluctuation of the pressure air supplied by the air compressor is released to a safe pressure in the water vapor separator, which ensures the continuity of the production of the air equipment and facilities of the mine enterprise. In view of this, we propose a mine-used water vapor separation device with overpressure protection. CONTENT OF THE UTILITY MODEL
