High-pressure modular underground centralized refrigeration device and system for mining

Abstract

The invention discloses a mining high-pressure modularization underground concentration refrigerating device and system. The mining high-pressure modularization underground concentration refrigerating device comprises a refrigeration and compression module, a high-pressure condensation module, a throttling expansion module, an evaporation cooling module, an oil path control module and a control system module; the refrigeration and compression module is used for preparing high-pressure high-temperature refrigerant vapor and outputting the high-pressure high-temperature refrigerant vapor to the high-pressure condensation module; the high-pressure condensation module is used for preparing high-pressure high-temperature refrigerant vapor output by the refrigeration and compression module to a high-pressure normal-temperature liquid refrigerant, and outputting the high-pressure normal-temperature liquid refrigerant to the throttling expansion module; the throttling expansion module is used for expanding the high-pressure normal-temperature liquid refrigerant to be a low-temperature normal-pressure gas refrigerant, and outputting the low-temperature normal-pressure gas refrigerant to the evaporation cooling module; the evaporation cooling module is used for evaporating and cooling the gas refrigerant, and outputting the processed gas refrigerant to the refrigeration and compression module; and the control system module uses a PLC (Programmable Logic Controller) to monitor above modules and display parameters through temperature and pressure sensors. With the adoption of the mining high-pressure modularization underground concentration refrigerating device and system provided by the invention, the problems of high pressure bearing, large heat exchange amount and small volume in a process for cooling a high-temperature deep well in China can be solved..

Description

technical field [0001] The invention relates to a mine-used high-pressure modular underground centralized refrigeration device, and also relates to an underground centralized refrigeration system. Background technique [0002] In recent years, with the increase of mine mining depth, the problem of high-temperature heat damage in mines in my country has become increasingly prominent, and the number of high-temperature mines has also increased. According to statistics, there are more than 130 pairs of mines in my country that have different degrees of high-temperature heat damage, of which more than 80 pairs of mines have adopted mechanical cooling measures. Various mine cooling systems currently used in practice can be divided into ice-making cooling, cooling water cooling and cooling air cooling according to the different cooling media. But no matter what kind of cooling medium, it will eventually be converted into cold air to reduce the air temperature of the underground m...

Problems solved by technology

But unfortunately, the underground centralized refrigeration devices used in these 12 sets of mine centralized refrigeration and cooling systems are all imported from abroad, and there is no similar type of underground centralized refrigeration devices in China. From this point of view, the development of domestic underground centralized refrigeration and cooling devices (this Invention) and applied to the practice of mine cooling, which is of special significance
