Description
(1) technical field
The present invention relates to a kind of cooling system, particularly a kind of type pit cooling system.
(2) background technology
Along with the increase of coal mining depth, down-hole mining place temperature raises gradually, and underground thermal pollution causes larger potential safety hazard, and even impact is normal produces." mine main getting working face air themperature must not more than 26 DEG C, and the air themperature of electromechanical equipment chamber must not more than 30 DEG C for " safety regulations in coal mine " the 102 article; When air themperature exceedes, the working time of overtemperature place staff must be shortened, and give high temperature health care treatment.The air themperature of getting working face more than 30 DEG C, the air themperature of electromechanical equipment chamber more than 34 DEG C time, must stop operation." gold mine, iron ore etc. also have similar regulation.
Current underground thermal pollution roughly has two types, and one is annual high temperature, and two is only summer high temperatures, and autumn, winter, spring downhole temperature are normal.The former generally takes mechanical refrigeration cooling system, has that cooling extent is large, equipment investment is high, operating cost high, is the emphasis of cooling research at present; If the latter also takes mechanical cooling measure, equipment only runs a season every year, and three seasons left unused, and waste is serious and maintenance cost is high.
Application number is that the patent of invention of CN201110237818 discloses a kind of system utilizing constant-temperature water bearing stratum to carry out mine cooling, and the advantage of this system is that the water temperature of thermostat layer is lower than surface water for summer, reduces refrigeration cost, but also there is following problem:
1. winter surface water temperature low compared with the water temperature of thermostat layer, adopt surface water more reasonable.
2. utilize water pump that the water of thermostat layer is extracted into ground and add power consumption, summer and air heat exchange, water temperature is increased significantly.
3. still freeze with ammonia stream separator, compressor, condenser etc., system is more complicated.
4. multiple systems exchange cold, efficiency reduces.
Because Virgin rock temperature is higher, water temperature in the low temperature sump of exploiting field rises obviously, especially the water yield little or off and on time, may reach water temperature consistent with Virgin rock temperature, cold is wasted huge.
(3) summary of the invention
The present invention, in order to make up the defect of prior art, provides the type pit cooling system that a kind of structure is simple, expense is low, good cooling effect, efficiency are high.
The present invention is achieved through the following technical solutions:
A kind of type pit cooling system, comprise downcast, it is characterized in that: also comprise cooling downcast, the cooling lane by several transverse directions after described cooling downcast leads to zone of constant temperature, stratum communicates with downcast, be provided with ventilating fan in the import of cooling downcast, be provided with cover plate in the import department of downcast.
Container or the spray header of dress ice is provided with in described cooling lane.
Described cooling lane is zigzag or waveform.
Be provided with open and close door in described cooling lane, described open and close door is positioned at the one end near downcast.
The invention has the beneficial effects as follows:
1, certain at vent line, wind speed, when distance change is little, air temperature rise from well head to getting working face is basicly stable, seasonal thermal post_buckling is mainly because well head EAT is too high, certain mine the highest EAT in observation summer reaches 29.2 DEG C, the trend that noon is high, night is low is obvious, so it is crucial for reducing EAT.The present invention starts with from source reduction temperature, compared with the loss can avoided in getting working face cooling in cold transmittance process and waste.
2, with the dark 50 ~ 55m in certain mine zone of constant temperature, temperature is 17.2 DEG C is example, if EAT can be reduced to this temperature, season, evil hot in nature can solve.The cold of zone of constant temperature is no longer extracted to ground by coolant transmission by the present invention, but is directly blown in the tunnel of zone of constant temperature by auxiliary ventilator by mine air intake, cools, and decreases interchange of heat link, improves refrigerating efficiency.
3, make full use of the natural resources, cancel mechanical cooling system, reduce refrigeration cost.
4, only need to close cooling lane, stop ventilating fan cold-storage in idle season.
5, after EAT reduces, the saturated humidity of air decreases, and has water-setting to go out during high humidity, is conducive to reducing underground air humidity, improves comfortable working environment degree.
6, larger to day and night temperature in summer mine, reduction EAT at noon is also effective.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is main TV structure schematic diagram of the present invention;
Fig. 2 is the plan structure schematic diagram of a kind of embodiment in cooling lane;
Fig. 3 is the plan structure schematic diagram of the another kind of embodiment in cooling lane.
In figure, 1 downcast, 2 ventilating fans, 3 cooling downcasts, 4 cooling lanes, 5 cover plates, 6 open and close doors, 7 zones of constant temperature, the container of 8 dress ice or spray header, 9 ground.
(5) detailed description of the invention
Accompanying drawing is specific embodiments of the invention.As shown in Figure 1, this kind of type pit cooling system, comprise the downcast 1 on ground less than 9, downcast 1 side excavation has cooling downcast 3, laterally dig several cooling lanes 4 after cooling downcast 3 leads to zone of constant temperature, stratum 7 to communicate with downcast 1, in order to strengthen cooling effect, container or the spray header 8 of dress ice can also be had additional in cooling lane 4; As shown in Figures 2 and 3, cooling lane 4 can design wave shape or zigzag, and such hot air just can absorb more cold air cooling lane 4, and cooling-down effect is better; With downcast 1 place of communicating, open and close door 6 is installed in cooling lane 4, is provided with ventilating fan 2 in the import of cooling downcast 3, is provided with cover plate 5 in the import department of downcast 1.
The course of work is as follows: in the summer high temperature time, EAT is higher, cover plate 5 is closed, wind can not be entered from downcast 1, open open and close door 6, start ventilating fan 2, wind enters from cooling downcast 3, and when supercooling lane 2, be subject to zone of constant temperature 7 and ice cube or spray water mitigation, temperature reduces, enter underground by downcast 1 again, good cooling-down effect can be reached.When time in leisure or winter, temperature was lower, open and close door 6 is closed, if at this moment also need to ventilate, then cover plate 5 is opened.
Except technical characteristic described in manual, all the other technical characteristics are those skilled in the art's known technology.
