Terminal flow amount adjustment device and mine cooling system

Abstract

The invention discloses a terminal flow amount adjustment device and a mine cooling system. The terminal flow amount adjustment device comprises a processing controller, a flow amount sensor, a temperature sensor I, a temperature sensor II and an electric adjustment valve, wherein the flow amount sensor is arranged on a water inlet side pipeline connected with an air cooler and detects the water flow amount in the water inlet side pipeline in real time; the temperature sensor I is arranged at the water inlet side pipeline and detects the water temperature in the water inlet side pipeline in real time; the temperature sensor II is arranged on a water outlet side pipeline connected with the air cooler and detects the water temperature in the water outlet side pipeline in real time; and the electric adjustment valve is arranged on the water inlet side pipeline and used for adjusting the flow amount of water entering the air cooler by controlling the valve opening degree. The mine cooling system comprises a ground refrigeration unit, a cooling tower, an over-mine circulation water pump, a high-pressure water depressurizing device, a downhole circulation water pump, the air cooler and the terminal flow amount adjustment device. The terminal flow amount adjustment device and the mine cooling system can realize coordination and matching of terminal heat loads and the cold water flow amount.

Description

technical field [0001] The invention relates to the field of mine cooling, in particular to a terminal flow regulating device used in a mine cooling system and a mine cooling system using the device. Background technique [0002] With the increase of mine mining depth, more and more mine cooling systems are used. The cold water is transported to the end of the air cooler through the insulation pipe to cool down. At present, the flow of cold water to the air cooler is generally constant. It often seriously exceeds the actual demand at the end, resulting in a waste of cooling capacity; in order to achieve the coordination and matching between the end heat load and the cold water flow, it is necessary to control the end flow through automatic control, which means that the end environment temperature is controlled Within a reasonable range, it will not cause the flow of cold water to be too large or too small. Contents of the invention [0003] In view of this, the object of ...
