Movable local cooling and dehumidification device for mine

Abstract

The invention discloses a movable local cooling and dehumidification device for a mine. The movable local cooling and dehumidification device comprises a movable base and a cooling and dehumidification system. The cooling and dehumidification system comprises a local ventilation fan, a gas filter, a dehumidifier, a liquid storage tank, a submersible pump, a main cooling pipe, a main reflux pipe, foam metal plates and jet heat pipes. The local ventilation fan is connected with the dehumidifier through an air duct. The gas filter is mounted on the air duct. The local ventilation fan, the air duct, the air filter and the dehumidifier together form a mine dehumidification system. The submersible pump is arranged in the liquid storage tank. The foam metal plates are mounted on the inner wall ofa mine surrounding rock roadway. The jet heat pipes are inserted in the foam metal plates. The liquid storage tank, the submersible pump, the main cooling pipe, the main reflux pipe, branch cooling pipes, branch reflux pipes, the foam metal plates, the jet heat pipes and the dehumidifier together form a mine cooling system. Local temperature and humidity of the working surface of the mine are improved, and coal mine production efficiency is improved. The structure is simple and the occupied area is small.

Description

technical field [0001] The invention belongs to the technical field of temperature and humidity regulation of surrounding rocks in deep mine roadways, and in particular relates to a mobile local cooling and dehumidification device for mines. Background technique [0002] With the development of deep coal mine operations in my country, high temperature heat damage in mines has become a major problem that threatens its safe production. There are many problems in the current mine cooling system: (1) Although the high-power refrigerator improves the cooling capacity, the cooling capacity loss is heavy during the long-distance underground transportation; As the working face advances, the dry and cold air blown to the working face must be mixed with the original air to make it heated and humidified. This situation will become more and more serious as the working face advances, resulting in a significant drop in cooling efficiency; (3) the existing cooling and dehumidification The...

There are many problems in the current mine cooling system: (1) Although the high-power refrigerator improves the cooling capacity, the cooling capacity loss is heavy during the long-distance underground transportation; As the working face advances, the dry and cold air blown to the working face must be mixed with the original air to make it heated and humidified. This situation will become more and more serious as the working face advances, resulting in a significant drop in cooling efficiency; (3) the existing cooling and dehumidification The system structure is complex, the equipment occupies a large area, and it is difficult to arrange; (4) the existing mine cooling device is difficult to move flexibly with the mining depth of the mine
