A mine heat exchange device

Abstract

The invention discloses a mine heat exchanging device which comprises a secondary evaporation chamber. A mine heat exchanging fan is connected to the front end of the secondary evaporation chamber and is connected to an air inlet of the secondary evaporation, compressed-air nozzles connected with an air compressor are arranged in the front end, corresponding to the air inlet, of the secondary evaporation chamber; water retaining plates are respectively arranged at the tail end and the top of the secondary evaporation chamber, and hot and humid air outlets are arranged in the outer sides of the water retaining plates; an S-shaped heat exchanging copper tube is arranged in the secondary evaporation chamber, a primary evaporation chamber is arranged at the upper end of the S-shaped heat exchanging copper tube, spray headers communicated with spraying water tubes are respectively arranged at the upper end of the primary evaporation chamber and between the S-shaped heat exchanging tube and the compressed-air nozzles, and a cooling water tank is arranged under the S-shaped heat exchanging tube; the lower ends of the water retaining plates extend to the lower side of the water surface of the cooling water tank. The mine heat exchanging device is high in heat exchanging rate, stable in heat exchange, low in loss of refrigeration capacity, compact in structure, small in size and long in service life.

Description

technical field [0001] The invention relates to a terminal device of a mine cooling system, in particular to a mine heat exchange device. Background technique [0002] With the continuous increase of mine mining depth and the continuous improvement of mining mechanization, mine high temperature heat damage has become a decisive factor affecting and restricting mining depth. Article 102 of the "Coal Mine Safety Regulations" stipulates that when the air temperature of the mining face exceeds 30°C and the air temperature of the mechanical and electrical equipment chamber exceeds 34°C, the operation must be stopped. The hazards of continuous high temperature and high humidity in the mine throughout the year and affecting the normal operation of mining work are called mine heat hazards. With the increase of mining depth, the number of hot mines in China is constantly increasing, and mine heat damage can no longer be solved by increasing mine ventilation or adopting other non-art...

AI Technical Summary

Problems solved by technology

[0004] The cooling efficiency of the current mine heat exchange device is low, and the hot and humid air is not pre-treated during heat exchange and cooling, resulting in poor cooling effect on the cooling water, the heat generated during cooling cannot be discharged in time, and the heat exchange tube is not easy to clean , affecting the efficiency of the entire cooling system
