The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1～12, the moving local air of the mining gas/liquid of the present embodiment is regulated unit, it comprises by pipeline circulate in turn compressor, condenser, expansion valve and the evaporimeter of the refrigeration system that connects into sealing, described refrigeration system inner sealing has cold-producing medium, described evaporimeter is supporting blower fan, described condenser is supporting have water tank and water pump, described compressor and blower fan be by air pressure or the moving compressor of hydraulically powered gas/liquid gentle/hydraulic fan.
The moving compressor of described gas/liquid is gentle/and hydraulic fan is connected with the pipeline of the compressed-air system/hydraulic system of mine, by the compressed-air system of mine/hydraulic system driving.
Be purifying power source, guarantee long-term, stable, the efficient operation of unit, the moving compressor of described gas/liquid is gentle/be provided with tertiary filter on the power intake line of hydraulic fan.
Liquid and the solid granulates of I level strainer energy filtering more than 3 microns of described tertiary filter reaches only 5ppm of minimum residual oil content; Can filtering little liquid and the solid granulates to 1 micron of the II level strainer of described tertiary filter reaches only 0.5ppm of minimum residual oil content; Can filtering little liquid and the solid granulates to 0.01 micron of the III level strainer of described tertiary filter reaches only 0.01ppm of minimum residual oil content.
