Abstract

The invention discloses a local ventilation and refrigeration combined high-temperature excavation roadway heat removal and cooling system. An artificial refrigeration and cooling system is formed by sequentially combining a refrigerating unit (1), an air supply local fan (2) and an air supply air duct (3), wherein a local ventilation system is formed by connecting an air exhaust local fan (4) and an air exhaust air duct (5); an air temperature sensor (11) is installed at the position 200-500mm away from an outlet of the air supply air duct (3); a dust sensor (12) is installed at the position 300-500 mm away from an inlet of the air exhaust local fan (4); and a PLC control system (6) automatically controls the refrigerating unit (1), the air supply local fan (2) and the air exhaust local fan (4) to be started, stopped and operated in a variable frequency mode. The local ventilation and refrigeration combined high-temperature excavation roadway heat removal and cooling system integrates ventilation and refrigeration and cooling with heat removal and cooling, has the advantages of being smooth in airflow organization, high in cooling speed and large in cooling amplitude, and can achieve dynamic real-time ventilation and cooling according to needs of high-temperature excavation roadway operation.

Description

technical field [0001] The invention belongs to the technical field of mine ventilation and cooling, and in particular relates to a high-temperature excavation roadway heat removal and cooling system combined with local ventilation and refrigeration, which can be widely used in the treatment of high-temperature heat damage during high-temperature excavation roadway operations in underground mine mining, and improves the working environment . Background technique [0002] During the excavation roadway operation, due to the inability to form through ventilation, the air flow lines of the entry and return air on the excavation face are in the same channel, and the fresh air and the polluted air interact with each other, which seriously affects the ventilation environment of the mine. When encountering high-temperature excavation roadway operations, the working environment of the excavation face further deteriorates. Aiming at the problem of heat dissipation and cooling in high...
