Embodiment Construction

[0024] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0025] Such as figure 1 As shown, sedimentation tank 1, sewage source plate heat exchanger 5, intermediate water system 6, water source heat pump unit 7, fresh air unit 8, and wellhead air heat exchanger 9 are connected in sequence, and sedimentation tank 1 is connected to sewage source plate heat exchanger 5 A purification and filtration system 14 is provided between them. The intermediary water system 6 includes a softening and descaling and water supply system. An induced draft fan 12 is installed on the waste heat pipe of the air compressor 3. The waste heat generated by the air compressor 3 is sent to the wellhead for heating through the induced draft fan 12. Cold air, coal gangue brick factory roasting kiln cooling section 2 is connected with fin heat exchanger 10 through pin heat exchanger 11 , and mine water clean water pool 4 is connected with ...

Abstract

The invention relates to the technical field of freeze protection for a coal mine well port in winter, in particular to an energy-saving anti-freezing system for the coal mine well port which makes use of a technique combining mine well water, afterheat and waste heat generated in each production link with a water source heat pump and adopts a digital central module control system and an integrated electric control system. The energy-saving anti-freezing system comprises a sedimentation tank (1), a coal gangue brick factory calcining kiln temperature-reducing segment (2), an air compressor (3), a mine well water clean-water pond (4), a plate type heat exchanger (5), an intermediary water system (6), a water source heat pump set (7), a new fan set (8), a well port air heat exchanger (9), afin type heat exchanger (10), a pin type heat exchanger (11), a draught fan (12) and a water pump (13). The energy-saving anti-freezing system solves the problems that the anti-freezing power consumption is high and the anti-freezing effect is poor in coal-fired boiler heating at the well port of coal mine in winter by utilizing afterheat and waste heat energy from mine drainage and production links, and water source heat pump technology, and has the advantages of saving energy, reducing production cost and improving the mine well environment and peripheral environment.

Description

technical field [0001] The invention relates to the technical field of winter antifreeze at coal mine wellheads, in particular to an energy-saving coal mine wellhead antifreeze system formed by utilizing mine water and waste heat generated in various production links, and waste heat combined with water source heat pump technology. Background technique [0002] Article 102 of my country's "Coal Mine Safety Regulations" stipulates that the air temperature (dry bulb temperature) below the air inlet wellhead must be above 2°C. Antifreeze at the wellhead is an important guarantee for the safe production of coal mines in winter. In winter, mines must take effective antifreeze measures to ensure that the wellhead temperature is above 2°C to prevent the wellhead from freezing. If the mine auxiliary shaft wellhead, cage and connecting device freeze in winter, when the ice melts, it may injure the tank crew, damage the main equipment in the wellhead and the suspended power cables, wh...
