Background technology
Along with the increase of coal mine mining depth, elevated temperature heat evil problem is more and more serious.Along with the increase gradually of the pit mining degree of depth and intensity, the improving constantly of mechanization degree, the temperature in underground work place increases substantially, and working environment runs down, and causes workman's operating efficiency to reduce greatly, and has increased the probability that has an accident greatly.Set up the suitable excavation operation environment in down-hole, the protection miner's is healthy, is the important leverage that guarantees mine safety, stable, High-efficient Production.Therefore need to reduce the mining face under mine temperature and humidity.
In order to reduce the operating temperature of mining face under mine, use methods such as increasing ventilation, ice making station, ground usually.After face air volume strengthens, the heat that the absolute thermal component of the face of adopting is assigned on the unit air volume reduces, wind-warm syndrome descends, and air quantity strengthens thereupon, and wind speed improves, help personnel's heat radiation, but along with down-hole country rock temperature further raises, increase the restriction that wind cooling is subjected to the high wind speed 4m/s of the face of adopting, lower the temperature and be difficult to meet the demands by increasing wind.Ice making station, ground has advantages such as cooling-down effect is obvious, but its equipment complexity needs many complete equipments such as refrigeration unit, slice ice machine, cooling tower, ice-melt pond to be used, and it is big therefore to have capital expenditure, shortcomings such as complicated operation, operating cost height.When adopting the cooling of ice making station, ground, its COP (Energy Efficiency Ratio) is worth generally below 1: 2, so its energy utilization rate is lower.
Water source heat pump units claims the water source central air-conditioning again, is to be thermal source or low-temperature receiver with water, can carry out the pump type heat enbloc air conditioner of refrigerating/heating circulation.Usually, the COP of water source heat pump units can reach 1: 5 or be higher, so advantage such as water source heat pump units has energy savings, reduces investment outlay, operating cost is low.Therefore, water source heat pump units has begun to be widely used recently.The CN201043829Y utility model patent discloses a kind of mine water source heat pump air-conditioner device, this device comprises water pump, water treatment facilities, water source heat pump units, circulating pump, heat exchanger etc., can be used for mine well head heating in winter and summer downhole cooling.Yet this aircondition is mainly used in mine well head heating in winter, and owing to there is not explosion-proof design, therefore can only be at the aboveground main frame that is provided with of mine, when cooling in summer, cold wind need be delivered to working face from well head, so transmission ﹠ distribution distance of its pipe network, in the process of transporting cold wind, cold wind is heated by the down-hole country rock, causes refrigeration to descend.
Therefore, need provide a kind of water source heat pump units that can be applied to the down-hole.
The utility model content
Therefore, the utility model provides a kind of water source heat pump units that is used under the coal mine, this unit comprises: by condenser, compressor, evaporimeter, the refrigerating circuit that expansion valve is linked in sequence and forms, automatically controlled part and surface cooler, described surface cooler is connected with evaporimeter by chilled water circulating pump, described condenser is connected with Mine Drainage System by pipeline, and the parts of the formation refrigerating circuit of described unit and automatically controlled part, surface cooler and chilled water circulating pump are explosion-proof design, can not cause in use that to guarantee unit burning or blast take place the imflammable gas in the environment.Wherein, described automatically controlled part has explosion-resistant enclosure, and described explosion-resistant enclosure is divided into equipment chamber and wire connection cavity, and the equipment chamber is used for holding control circuit and control element, and control circuit and external equipment are connected to each other by wire connection cavity.
The chilled water that produces in the evaporimeter is delivered to surface cooler through chilled water circulating pump, and the cold air that produces by surface cooler is transported near the down-hole mining working face, to lower the temperature.
The mine water that carries out after the heat exchange with condenser is disposed to ground by Mine Drainage System.
This water source heat pump units also can comprise running gear, so that it can move easily with the passing of working face.
Therefore, advantage of the present utility model is: owing to used explosion-proof design, therefore unit can be arranged near the getting working face, thereby can reduce the transmission ﹠ distribution distance of pipe network, can improve refrigeration, save power consumption and reduce capital expenditure.
Description of drawings
By the description of carrying out below in conjunction with accompanying drawing to embodiment, above-mentioned and/or other purposes of the present utility model and advantage will become apparent, wherein:
Fig. 1 is the schematic diagram according to water source heat pump units under the coal mine of the present utility model.
Fig. 2 is the schematic diagram according to the automatically controlled part of water source heat pump units under the coal mine of the present utility model.
The specific embodiment
Embodiment is described in detail the utility model below by reference.
With reference to Fig. 1, can comprise: parts such as condenser 1, evaporimeter 2, compressor 3, expansion valve 4, automatically controlled part (not shown in Fig. 1), chilled water circulating pump 5, surface cooler 6 according to water source heat pump units under the coal mine of the present utility model.Wherein, condenser 1, compressor 3, evaporimeter 2, the expansion valve 4 formation refrigerating circuit that is linked in sequence.Surface cooler 6 is connected with evaporimeter 2 by chilled water circulating pump 5, and condenser 1 is connected with Mine Drainage System by pipeline.
The course of work according to the cooling condition of water source heat pump units under the coal mine of this enforcement is: at first by compressor 3 absorption refrigeration agent steam from evaporimeter 2, to guarantee to keep in the evaporimeter 2 evaporating pressure about about 0.4MPa and 2 ℃ to 4 ℃ evaporating temperature, under this temperature, pressure, cold-producing medium in the evaporimeter constantly evaporates the also heat of absorption refrigerating water, to keep the leaving water temperature of 7 ℃ of chilled waters.Chilled water is delivered to the surface cooler 6 of getting working face through chilled water circulating pump 5, with the heat exchange of air duct air distribution to produce cold wind, so that working face is lowered the temperature.By compressor work the refrigerant vapor compression of low-pressure low-temperature is become 2.0MPa, 70 ℃ to 80 ℃ superheated steam, cooling is condensed into liquid state by gaseous state through mine drainage, and in this process, having discharged condensation waste heat, the mine drainage that has absorbed condensation waste heat drains into ground with Mine Drainage System.
