Background technology
Development along with China's mining technique, the mining degree of depth increases gradually, and ground temperature progressively raises, and the degree of depth surpasses 800m and generally all reached later on the above heat evil of secondary, original aeration-cooling mode can't satisfy the cooling needs, has increasing mine to begin to set up mechanical cooling system.The centralized ice cooling temperature reduction system in ground is a kind of mechanical cooling method commonly used, main feature cooling refrigeration main frame and cooling water system and equipment are located at ground, the down-hole arranges ice-melting pool, the mixture of ice and water that the ground refrigeration unit is made is delivered to underground ice-melting pool by insulated piping, is delivered to from ice-melting pool and uses cold place.This cooling method has the following advantages:
1. the centralized operational management in ground is convenient, good heat dissipation effect.
2. avoided the refrigeration host computer down-hole to reveal the refrigerant problem, safety is good.
3. without the high-pressure system link, the equipment Pipe-Line bearing capacity requires low, and safety is good, invests low.
4. mixture of ice and water uses cold water refrigerating amount large, and water supply volume is few, and running efficiency of system is high.
5. ice-melting pool has the cold-storage ability, has improved the reliability of system.
In actual motion, also find some shortcomings, be embodied in mainly containing of ice-melting pool aspect:
1. the ice-melting pool capacity that is welded of metal material is less, and hydraulic overflow problem easily occurs, and thermal loss is large.
2. the ice-melting pool corrosion-resistant that is welded of metal material needs periodic replacement, and impact is used.
3. because the flowability of mixture of ice and water is slightly poor, plugging easily occurs in the access pipeline, and system reliability is poor.
4. ice-melting pool cold water does not out have pressure, need to be pumped to and use cold place, has increased power consumption and heat radiation.
Summary of the invention
The present invention is in order to remedy the deficiencies in the prior art, a kind of energy-conservation, good reliability, long service life is provided, prevented interchange of heat chamber under the mine of spilling water.
The present invention is achieved through the following technical solutions:
The interchange of heat chamber comprises ice-melting pool under the mine of the present invention, and ice-melting pool top connects input pipe and return pipe, the bottom connects efferent duct, it is characterized in that: ice-melting pool adopts vertical ice-melting pool static pressure outwards to supply cold water, and the pool wall of ice-melting pool adopts the enclosure of concrete supporting, and is inner with insulation layer; Water-level instrumentation is installed in the ice-melting pool; Input pipe is downward-sloping.
Preferred version is, described ice-melting pool top is thick, the bottom is thinner, and there is the back taper changeover portion at the middle part.Input pipe and efferent duct are established respectively one or more.The ice-melting pool upper and lower is cylindrical, and the middle part is turbination.
The invention has the beneficial effects as follows, improve the centralized ice cooling temperature reduction system in ground, improve underground labour's working environment, improve job security.This product capacity is large, is difficult for hydraulic overflow problem occurs, and thermal loss is little, good corrosion resistance, and the life-span is long, is difficult for plugging, and good reliability does not need to use pump, and saves energy avoids the heat of pump harmful.
Description of drawings
Fig. 1 is schematic top plan view of the present invention.Fig. 2 is that master of the present invention looks schematic diagram.
Among the figure, 1 ice-melting pool, 2 input pipes, 3 return pipes, 4 water-level instrumentations, 5 enclosure wall supportings, 6 efferent ducts.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
Interchange of heat chamber under the mine of the present invention comprises ice-melting pool 1, and ice-melting pool top connects input pipe 2 and return pipe 3, the bottom connects efferent duct 6, ice-melting pool adopts vertical ice-melting pool static pressure outwards to supply cold water, and the pool wall of ice-melting pool adopts enclosure of concrete supporting 5, and is inner with insulation layer; Water-level instrumentation 4 is installed in the ice-melting pool; Input pipe is downward-sloping.Ice-melting pool top is thick, the bottom is thinner, and there is the back taper changeover portion at the middle part.Input pipe and efferent duct are established respectively one or more.The ice-melting pool upper and lower is cylindrical, and the middle part is turbination.Input pipe leads to pit shaft.
Interchange of heat chamber under the mine of the present invention has the following advantages:
1, adopt the vertical ice-melting pool 1 interior hydrostatic pressure that generally has more than the 20m, outlet pipe 6 water out can flow automatically to by static pressure and use cold place, has reduced power consumption and heat radiation.Outlet pipe and oral siphon can be established a plurality of.The ice-melt chamber adopts the vertical static pressure to supply water, and shape is not limited to cylindrical, and taper shape, infundibulate, inclined to one side infundibulate can.
2, the ice-melt chamber is the chamber that arranges in the country rock of down-hole, and ice-melting pool adopts concrete support, can establish insulation layer, has avoided adopting the etching problem of metal material.
3, do the ice-melting pool concrete support in the country rock of down-hole, fully capacity increasing cooperates automatic monitoring, has avoided overflowing water problem fully.The carrier pipe 2 capacity 56.5m of the 300mm diameter that for example 800m is dark
3, ice-melting pool 6 is made the cylinder of the dark 3m diameter of 30m, capacity 2125m
3, by water-level instrumentation 4, find that residual volume will be less than 56.5 m in the ice-melting pool
3, and during outlet pipe 5 not water outlet, ground stops to carry automatically, can avoid the generation of spilling water phenomenon.
4, adopt the cylinder type ice-melting pool, static pressure outwards supplies cold water, and interchange of heat is more even.After the mixture of ice and water that transports by carrier pipe 2 entered ice-melting pool 6, ice concentration floated over top less than water; Cold water is to sinking; The water of returning by return pipe contacts first rapidly cooling with floating superincumbent ice, cold and hot convection current in the whole ice-melting pool, and interchange of heat is more abundant.
5, carrier pipe 2 is not that level enters ice-melting pool 6, but the elevation angle of α is arranged, and has avoided the problem of 90 ° of easy pluggings in turning of carrier pipe, and system reliability is high.
