Heat power system of deep well mining and with heat storage water tank

Abstract

The invention provides a heat power system of deep well mining and with a heat storage water tank. A cooling water tower is arranged in an air return well, and an evaporator, an expansion valve, a compressor and a condenser are located in an underground chamber, so that a cooling system is formed. An air cooler is arranged on the working face. The heat storage water tank and the condenser are combined to form a heat storage water tank circulation pipeline, and the evaporator and the air cooler are combined to form an air cooler circulation pipeline. After the water in the air cooler and the air on the working face conduct heat exchange, the water circulates to the evaporator to conduct heat exchange. After the water in the heat storage water tank enters the condenser, the water absorbs theheat in the condenser and then circulates to return to the heat storage water tank. According to the heat power system of deep well mining and with the heat storage water tank, due to the fact that the heat storage water tank is arranged, the function that the domestic hot water is provided by the heating end can be fulfilled, and the heat power system has the advantages of being high in heat efficiency, long in conveying distance, compact in equipment and high in safety, and is quite suitable for the deep well operation.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a thermal system for deep well mining. Background technique [0002] In the process of deep mine mining, the problem of deterioration of underground thermal environment is very prominent. As the mining depth of the mine increases, after entering the deep part, the working face of the mine begins to be affected by high temperature, which not only restricts the safe production and construction of the mine, but also threatens the health of the miners. my country's "Safety Regulations for Metal and Nonmetal Mine" stipulates that the air temperature of the mining face of the production mine shall not exceed 26°C, and the air temperature of the electromechanical equipment chamber shall not exceed 30°C. When the air temperature of the above two working places exceeds 30°C and 34°C The job must be stopped. At the same time, due to the needs of the process, the mining process wil...

AI Technical Summary

Problems solved by technology

Existing problems include: the effect of the ventilation system becomes worse with the increase of the working depth; the cost of workers’ cooling clothes is high, and the operation process is inconvenient; the underground refrigerator has difficulty in heat dissipation, and the use of air as the heat dissipation medium leads to poor cooling effect and high operating costs, etc. question

Fluid-induced vibration can cause severe noise and damage to the heat transfer tube bundle, and fouling on the surface of the heat transfer tube bundle can cause huge energy and resource losses
