Detailed description of the invention
The exemplary embodiments that embodies feature & benefits of the present invention will describe in detail in the following description. Ying LiWhat separate is that the present invention can have various variations on different embodiment, and it neither departs from of the present inventionScope, and explanation wherein and accompanying drawing be when the use that explain in itself, but not in order to limit the present invention.
Mine cooling method taking geothermal using cold energy as low-temperature receiver with low temperature tunnel in superficial part rock stratum aroundRock stratum, as low-temperature receiver, utilizes heat exchanger tube heat transfer technology, taking water as medium, high-temperature water is transported to through pipelineIn heat exchanger tube in low temperature tunnel, allow high-temperature water and low temperature tunnel carry out sufficient heat exchange, thereby extract lowCold in temperature rock stratum, and cooling water is transported to refrigeration work station through pipeline transportation by cold energy, makeAfter cold energy, utilizing circulating water body to be delivered to needs near the cooling work station of the working face of cooling to working face windStream is lowered the temperature.
As depicted in figs. 1 and 2, deep layer type pit cooling system of the present invention comprises low-temperature receiver extraction station 1, systemCold work station 3 and cooling work station 5. Wherein, low-temperature receiver extraction station 1 is arranged at the low temperature of superficial part rock stratum 7In tunnel 10, this low temperature tunnel 10 can be that formation is set specially, can be also to excavate shallow-layer coal early stageThe tunnel that charcoal is discarded. Low-temperature receiver extraction station 1 includes and multiplely inserts superficial part rock stratum 7 by low temperature tunnel 10In heat exchanger tube 11, to draw the cold of superficial part rock stratum 7.
As shown in Figure 2, low-temperature receiver extraction station 1 comprises multiple the carrying of being parallel to each other that are arranged at low temperature tunnel 10Get face 101,102 etc., multiple heat exchanger tubes 11 are evenly set in each extraction face, heat exchanger tube 11 is along low temperatureTunnel 10 radially arranges, to draw as much as possible cold. Wherein, distance L between every two extraction facesAnd between every two heat exchanger tubes 11, spacing is determined according to actual needs. In the present invention, heat exchanger tube 11 is U-shapedPipe, the equal connecting pipe 2 of its both ends open, this pipeline 2 connects low-temperature receiver extraction station 1 and refrigeration work station 3,It uses fluid as heat exchange medium, and this fluid is water conventionally, adopts pump as drive unit. PreferablyGround, heat exchanger tube 11 is underground pipe, adopts pvc pipe material.
In the present invention, refrigeration work station 3 includes refrigeration machine, and refrigeration machine is communicated with low-temperature receiver by pipeline 2 and carriesGet station 1, and flow alternately in pipeline 2 by drive unit drive fluid, this drive unit is conventionallyPump, is transported to low-temperature receiver extraction station 1 by hot water from refrigeration work station 3 by pump, and cooling water is carried from low-temperature receiverGet station 1 and be transported to refrigeration work station 3. Refrigeration machine in refrigeration work station 3 obtains cold energy from cooling waterAnd be converted into the cold energy that quality is higher, to flow to cooling work station 5.
In the present invention, cooling work station 5 is arranged at working face 6 entrances of deep layer mine, includes air coolingDevice and blower fan, the cooling fluid that air cooler comes by 3 transmission of refrigeration work station is by the air intake sky of working face 6Temperature degree reduces, and it (is working face that blower fan is transported in the coal cutting roadway of deep layer mine by the air after coolingIn 6), realize the cooling of deep layer mine.
Elaborate taking an application colliery of the present invention cooling system as concrete example below:
The dark 1200m of this Coal Exploitation, 50 DEG C of deep rock Wen Gaoda, 36 DEG C of working face air themperatures, relativeHumidity 100%. Simultaneously anterior-260 horizontal rock temperature are 18 DEG C, have a large amount of natural cold in ground temperature rock stratumSource, simultaneously-260 levels have has exploited complete waste and old tunnel in a large number.
In this example, as shown in Figure 3, deep layer type pit cooling system also comprises pressure switching station 8, pressesPower switching station 8 is arranged between refrigeration work station 3 and cooling work station 5, to the fluid of uplink and downlinkCarry out pressure conversion. Pressure switching station 8 is divided into primary side and secondary side, and primary side is from refrigeration work station3 fluids that get off, secondary side be go to cooling work station 5 fluid, between two side liquids by heat exchangePipe conducts heat, thereby by being divided into two sections from refrigeration work station 3 to the fluid cooling work station 5, reducesThe hydrostatic pressure of fluid in pipeline.
The detailed process of this example is: the hot blast of working face 6 is 32 DEG C, circulate by cooling work station 5,Cooling medium (being water in this example) heating that makes to lower the temperature in work station 5, by pressure switching station 8Behind refrigeration work station 3, this hot water reaches 35-38 DEG C, and last refrigeration work station 3 is to low-temperature receiver extraction station 1Carry this hot water. The temperature of the residing superficial part of low-temperature receiver extraction station 1 rock stratum 7 is at 18-21 DEG C, this hot water warpAfter low-temperature receiver extraction station 1 is cooling, reduce to 28 DEG C, send refrigeration work station 3 back to and process and become through refrigeration againThe cooling water of 9-13 DEG C, then be transported to pressure switching station 8, is warming up to 16-20 DEG C and be transported to cooling at thisWork station 5, it is cooling that cooling work station 5 utilizes this cooling water to carry out hot blast, and be cooled to after 23.25 DEG CBe delivered in working face 6.
Beneficial effect of the present invention is, the low-temperature receiver extraction station 1 in the present invention is arranged at superficial part rock stratum 7In low temperature tunnel 10, in superficial part rock stratum 7, obtain cold by heat exchanger tube 11, then pass through refrigeration workStand 3 and cooling work station 5 conversion in the tunnel of deep layer mine, input cold air, due to superficial part rock stratum 7Middle cold abundance, therefore cooling efficiency of the present invention is high, obtains cold in addition, nothing by superficial part rock stratum 7Cooling device must be set on the ground, pipeline compared with short, discharge pressure is little, and the present invention is not subject in mineWhether there is the restriction of a large amount of swallets, applied widely.
Technical scheme of the present invention is disclosed as above by preferred embodiment. Those skilled in the art should realizeTo in the case of not departing from institute the scope and spirit of the present invention that the appended claim of the present invention disclosesChange and the retouching done, within all belonging to the protection domain of claim of the present invention.
