[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:
[0024] Reference Figure 1-5 A mining nitrogen cooling device comprises a mining flatbed car 14 and an electric control box 15. A shell and tube evaporator 3 is provided on one side edge of the surface of the mining flatbed car 14. A gas-liquid separator 2 is connected to the side of the shell and tube evaporator 3. A compressor 1 is provided on the surface of the mining flatbed car 14. An electric pump is connected to the end of the compressor 1. An air intake filter 12 is provided between the gas-liquid separator 2 and the electric pump. A stop valve 11 is installed between the air intake filter 12 and the gas-liquid separator 2. When nitrogen is initially treated, it enters through the nitrogen inlet on the surface of the shell and tube evaporator 3 and circulates through the air intake pipe connected between the shell and tube evaporator 3 and the gas-liquid separator 2. After the nitrogen enters the gas-liquid separator 2, the nitrogen and the liquid are separated. When the stop valve 11 is opened, the separated nitrogen enters the air intake filter 12 through the air intake pipe between the gas-liquid separator 2 and the air intake filter 12 to filter the gas, thereby completing the first stage of stratified filtration treatment of the nitrogen.
[0025] When the second stage of nitrogen treatment is carried out, since one side of the gas-liquid separator 2 is connected to the oil-gas separator 8 through an electric pump, the nitrogen treated in the first stage, under the extraction of the electric pump, enters the oil-gas separator 8 through the exhaust pipe between the electric pump and the oil-gas separator 8, and is filtered for gas-oil separation through the oil-gas separator 8. The separated nitrogen flows out along the top of the oil-gas separator 8, and the separated oily substance flows out along the bottom of the oil-gas separator 8.
[0026] When processing the separated oily matter, since an oil cooler 9 is connected to the bottom end of the oil-gas separator 8, an oil pump 10 is connected between the oil cooler 9 and the electric pump, a special switch and a refueling port are provided on the surface of the oil-gas separator 8, and a stop valve 11 is provided at the outlet position of the bottom end of the oil-gas separator 8, the oily matter flowing out from the bottom enters the oil cooler 9 through a pipeline when the stop valve 11 is opened, and an oil cooling fan is provided on the surface of the oil cooler 9. After the heat is dissipated, the oily matter flows out and enters the oil filter 13 for filtration. The filtered oily matter flows through the connected oil pump 10, and is connected to the electric pump through the main oil circuit solenoid valve connected on the surface for centralized collection.
[0027] After the separated nitrogen is processed, since the top of the oil-gas separator 8 of the equipment is connected with a condenser 7, the oil-gas separator 8 is connected to the condenser 7 through an exhaust pipe, and one end of the condenser 7 is connected with a liquid reservoir 6 through a liquid pipe, and a stop valve 11 is provided at the liquid inlet of the liquid reservoir 6. The nitrogen flows through the exhaust pipe and passes through the condenser 7 for air cooling. The cooled liquid nitrogen enters the liquid reservoir 6 through the liquid pipe. The bottom of the liquid reservoir 6 is connected to the liquid pipe through the stop valve 11, and the end of the liquid pipe is connected to a drying filter. The drying filter is connected to the economizer 5 through a liquid pipe. The liquid nitrogen inside the liquid reservoir 6 enters the drying filter through the liquid pipe for filtration and then enters the economizer 5. An economizer 5 is connected between the liquid reservoir 6 and the shell and tube evaporator 3. The liquid nitrogen entering the economizer 5 is heat exchanged. The liquid pipe at the bottom of the economizer 5 is connected to the stop valve 11, the main solenoid valve and the expansion valve 4 and then connected to the shell and tube evaporator 3. The liquid nitrogen after heat exchange enters the shell and tube evaporator 3 after each valve body is opened, and is finally discharged through the nitrogen outlet of the shell and tube evaporator 3.

The separated oil is filtered and diverted, so that the entire device is integrated to cool the nitrogen. After the nitrogen is introduced, the opening and closing of each device and the switch of the valve body are controlled by the electric control box 15 to control the flow direction of the nitrogen, and finally realize the cooling after separation. After the integration degree, the nitrogen enters at an initial temperature of 25°C, and the temperature of the cooled nitrogen is -30°C. The processing equipment is complete and installed through the mining flatbed car 14, which is easy to move and transport, and is used for nitrogen cooling during outdoor mobile use.
