Mine underground cooling and dehumidifying device and method

Abstract

The invention discloses a mine underground cooling and dehumidifying device and method. The mine underground cooling and dehumidifying device comprises a movable base and further comprises a cooling and dehumidifying system arranged on the movable base, wherein the cooling and dehumidifying system comprises a ventilator and a dehumidifying mechanism; a gas filter is arranged between the ventilatorand the dehumidifying mechanism; an air outlet of the dehumidifying mechanism is provided with an air collecting cover in a matched mode; the air outlet end of the air collecting cover is connected with one end of an air cooler in a sealed mode; the other end of the air cooler is connected with an air inlet of an air collecting box in a sealed mode; an air outlet of the air collecting box is connected with one end of a main air barrel in a sealed mode; and the other end of the main air barrel is provided with a horn-shaped spray head. The mine underground cooling and dehumidifying method comprises the following steps that the ventilator and a third motor are started, and the third motor drives fan blades of the main air barrel to rotate so as to spray cold air out through the spray head at the front end of the main air barrel. According to the mine underground cooling and dehumidifying device and method, the loss of the cooling capacity is reduced, the amount of sucked moisture is reduced, and the cooling and dehumidifying effects are more obvious.

Description

technical field [0001] The invention relates to a device and a method, in particular to a mine well cooling and dehumidification device and method. Background technique [0002] The underground temperature of coal mines continues to rise as the depth of mining increases. Underground mining workers often work under high temperatures. The ambient temperature in the mine exceeds the temperature that the human body can tolerate in normal thermal balance, resulting in reduced labor efficiency, increased accident frequency, and impaired health. Even heatstroke shock, the temperature in the deeper mine is not only high but also the air is humid, the working environment of the staff is poor, which brings inconvenience to the work of the staff, so it is necessary to ventilate and cool down the mine to ensure the normal work of the staff. [0003] There are many problems in the current mine cooling system: 1) Although the high-power refrigerator improves the cooling capacity, the cool...

[0002] The underground temperature of coal mines continues to rise as the depth of mining increases. Underground mining workers often work under high temperatures. The ambient temperature in the mine exceeds the temperature that the human body can tolerate in normal thermal balance, resulting in reduced labor efficiency, increased accident frequency, and impaired health. Even heatstroke shock, the temperature in the deep mine is not only high but also the air is humid, the working environment of the staff is poor, which brings inconvenience to the work of the staff, so it is necessary to ventilate and cool down the mine to ensure the normal work of the staff

[0003] 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; 2) As the working face advances, The dry and cold air blowing 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 system has a complex structure , the equipment occupies a large area and is difficult to arrange; 4) the existing mine cooling device is difficult to move flexibly with the mining depth of the mine; To cool down, but the spraying diameter of the spraying device is fixed, resulting in a small coverage of the sprayed spray
