The high-pressure condenser for coal mine refrigeration comprises a condenser tube body (10), a seal head (6), a cooling tower (1) and the like, wherein an underground circulating water pump (4) is arranged on the connecting position of a cooling water backwater pipeline (2) and the condenser tube body (10), and two ends of the condenser tube body (10) are provided with a pipe plate (7) and a tube body (10) which are connected with flanges (5,8) on two ends of the seal head (6), a plurality groups of U-shaped heat exchange pipes (11) are arranged in the tube body (10), two end caps of the heat exchange pipes (11) are communicated with a front and a rear cavity bodies (15, 14) outside the pipe plate (7), the left end of the tube body (10) is provided with a cooling medium outlet (9), and the right end is provided with a cooling medium inlet (13) and a drainage pipe (12). The high-pressure condenser for coal mine refrigeration has explosion-proof performance, simple structure and convenient maintenance, is environmental-friendly and energy-saving, can bear high pressure, is not easy to block pipelines, can resist corrosion of underground environment, and satisfies the requirements of refrigeration of underground refrigerating units.
Description
Technical field
The utility model belongs to refrigeration plant, the cooling high pressure condenser in particularly a kind of colliery.
Background technology
At present, because a large amount of exploitations of coal in China, some areas line layer coal is near exhausted, for satisfying development need, the dark coal seam of recovery of subterranean just progressively, and along with the temperature in the intensification mine of the degree of depth is also rising, the draining pressure of supply water is improved, the heat that working face rock heat and electrical equipment produce makes down-hole ambient temperature individual work face reach 40 ℃, has a strong impact on workman's normal operation, strengthened the possibility of fire and gas explosion, it is imperative to solve the refrigeration of underground mine cooling system, and existing common low-pressure condenser does not satisfy the demand of equipment, and cooling water must reduce pressure, not only can produce a large amount of heat, also must additionally increase the installation cost and the running cost of water lift, cause waste, improve cost.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of colliery simple in structure, easy to maintenance, energy-conserving and environment-protective cooling high pressure condenser.
The technical scheme that the utility model technical solution problem adopts is: the cooling high pressure condenser in colliery comprises the condenser cylindrical shell, end socket, cooling tower, the cooling water inlet pipe road, the CWR road, be characterized in being provided with the down-hole water circulating pump on CWR road and condenser cylindrical shell junction, establish tube sheet is connected with the flange of cylindrical shell with the end socket two ends at condenser cylindrical shell two ends, in cylindrical shell, be provided with the heat exchanger tube of many group U-shapeds, before outside heat exchanger tube two ends and the tube sheet, rear chamber is communicated with, left end is established refrigerant exit on cylindrical shell, right-hand member is established refrigerant import and blow-off pipe, and the cooling water inlet pipe road is connected cooling tower respectively with water return pipeline.
The beneficial effects of the utility model are: owing to be provided with the U-shaped heat exchanger tube at the cylindrical shell adpting flange, only need input energy seldom, cooling water is circulated, and has an explosion-proof performance, simple in structure, easy to maintenance, environmental protection and energy saving can be born high pressure, and pipeline is difficult for stopping up, down-hole refrigeration unit refrigeration needs are satisfied in anti-subsurface environment corrosion.
