The centralized cooling and air feeding balance control device comprises a water storage tank, wherein two groups of air-water heat exchanging units are installed in the water storage tank, a group of air-water heat exchanging units are connected with a cooling cold water supply pipe, the other group of air-water heat exchanging units are connected with the water storage tank through a spraying circulation pipe, the upper portion of the water storage tank is provided with a device outside structure, one side is an air flow inlet end, the other side of an air flow outlet end, two ends of the device outside structure are both provided with air pressure transmitters and used for detecting an outlet air pressure and an inlet air pressure, a water baffle adjusting and controlling device is used for controlling the air outlet direction and size of an adjustable water baffle, and a spraying pipe adjusting and controlling device is used for controlling spray head directions of the air-water heat exchanging units.
Description
Technical field [0001] The invention relates to a centralized cooling and air supply balance control device in a coal mining area. Background technique [0002] As the depth of coal mining increases, the impact of high-temperature thermal damage is increasing. The situation where the entire mining area or the entire mine is subject to high-temperature thermal damage is called normal. However, the implementation of the mechanical cooling system in the entire mining area inevitably requires the installation of air-conditioning equipment for cooling air flow in the roadway of the mining area, which will change the balance of the original underground ventilation network and may make the air volume of each mining area unable to meet the requirements. Summary of the invention [0003] The purpose of the present invention is to provide a centralized active cooling and air supply balance control device for coal mining areas, which will adjust the wind resistance of air conditioning equipm...
