Movable type driving roadway cooling device

Abstract

The invention discloses a movable type driving roadway cooling device. The movable type driving roadway cooling device comprises an air supply roadway and a movable platform, wherein the movable platform is movably arranged in the air supply roadway; a heat insulation plate is arranged on the movable platform; a cold radiation aluminum plate with copper pipes is arranged on the inner side of the heat insulation plate; the cold radiation aluminum plate with the copper pipes comprises a radiation aluminum plate and cold water copper pipes; and a plurality of cold water copper pipes are arrangedon the radiation aluminum plate at equal intervals. The movable platform and a movable cold source are movable and can move forwards according to the advancing of a driving working face. The heat insulation plate is additionally arranged on the outer side of the radiation aluminum plate, so that the heat transfer amount from surrounding rock outside the air supply roadway to a main roadway is reduced, and the moisture transfer amount from the surrounding rock to the main roadway is isolated; the cold water copper pipes are integrally formed on the radiation aluminum plate, the movable cold source is communicated through a cold water supply pipe and a cold water return pipe, a temperature sensor is arranged on the cold water supply pipe, and the water supply temperature is controlled to be15 DEG C, so that the temperature and humidity of air flow can be effectively reduced, and the heat comfort degree of a human body can be improved.

Description

Technical field [0001] The invention relates to the technical field of mine cooling, in particular to a mobile driving tunnel cooling equipment. Background technique [0002] With the increase of mining depth and the continuous improvement of the degree of mechanization, the heat hazard in the mine is becoming more and more prominent, which has become one of the major problems restricting the safe mining of the mine. By 2010, the air current temperature of 35% of the mining face in China’s coal mines exceeded 30℃. According to the current resource mining situation, the mining depth of coal mines in China is increasing at a rate of 8-12m per year, especially in the eastern part of China, which is developing at a rate of 100-250m every 10 years. In recent years, a batch of mines have been mining depths exceeding 1000m. Test analysis data It shows that the temperature of rock formations below 1000m in China's main coal distribution areas reaches 35-45℃, and the temperature of rock f...

Problems solved by technology

[0005] Throughout the domestic and foreign methods of controlling mine heat damage, they can be generally divided into non-artificial cooling methods and artificial cooling methods. The former mainly increases the air volume, changes the ventilation mode, avoids local heat sources, pre-cools the air flow, and isolates high temperature. Surrounding rock and hot water prevention and control have successfully achieved non-artificial cooling, but improving ventilation methods and increasing air volume are affected by the temperature of the inlet air and surrounding rock, and the cooling range is very limited. The latter mainly uses mine air conditioners for cooling and cooling. : local air conditioner, underground water source heat pump air conditioner, mine air refrigerator, ground centralized type, underground centralized type, ice-cooling cooling system, etc., ground centralized type, underground centralized type, ice-cooling cooling system, etc. The system is more complicated and the initial investment is large , high operating cost, large amount of installation and maintenance engineering, mainly used for cooling large mines with a cooling capacity of more than 5000k W, while other mine artificial cooling cooling methods are suitable for some small production mines with a cooling capacity of 3000k W, centralized refrigeration Another significant defect of the main mine cooling method is that the long-distance transportation has a large amount of cold loss. According to the conditions of Suncun, Pingba Mine and foreign countries, the system cold loss can reach 20%. Therefore, the present invention proposes a mobile Type tunneling roadway cooling equipment to solve the problems existing in the prior art
