Description

Technical Field

[0001] The utility model relates to the technical field of compression condensing machines, in particular to an air-cooled double-channel explosion-proof compression condensing unit. Background Art

[0002] Generally, the demand for oil and gas recovery condensing devices is below -25°C, and the evaporation temperature of the evaporator of the first cold box and the evaporator of the second cold box are both below -35°C. This requires the air-cooled compression condensing unit to operate under low temperature conditions. When the unit operates under low temperature conditions, frost will form on the inner and outer surfaces of the evaporator of the first cold box and the evaporator of the second cold box. If defrosting is not done in time, the oil and gas circulation of the unit will be blocked.

[0003] In the patent with publication number CN220287831U, an air-cooled dual-channel explosion-proof compression condensing unit is proposed, which includes an explosion-proof compressor, an oil separator, an explosion-proof air-cooled condenser, a liquid storage tank, a gas-liquid separator, a constant pressure valve, a first cold box, a first evaporator, a first expansion valve, a second expansion valve, a second explosion-proof solenoid valve, a second non-return valve, and a second defrost valve. When the explosion-proof compressor 3 is running, the exhaust passes through the oil separator 2. After preliminary oil separation, the high-temperature oil and gas pass through the constant pressure valve 20 (during normal operation, the constant pressure valve is always open) to enter the explosion-proof air-cooled condenser 1, and then enter the liquid storage tank 5, pass through the first explosion-proof solenoid valve 10, throttle and reduce the pressure through the first expansion valve 11, evaporate in the first evaporator 8 of the first cold box 6, and then enter the gas-liquid separator 4 through the first return air valve 18 of the first cold box 6, and then return to the explosion-proof solenoid valve 10. The explosion-proof compressor 3 is circulated again; defrosting of channel A: the explosion-proof compressor 3 is running, and the exhaust passes through the oil separator 2. After the preliminary oil separation, the high-temperature Freon is divided into two directions. One part passes through the first defrost valve 16 and directly enters the first evaporator 8 of the first cold box 6. The hot gas is condensed through the first cold box 6, and then passes through the first one-way valve 14 to enter the liquid storage tank 5. The other way of the outlet of the oil separator 2 passes through the constant pressure valve 20. The constant pressure valve 20 works, and then passes through the explosion-proof air-cooled condenser 1 for condensation and pressure reduction, and then enters the liquid storage tank 5, and then passes through the second explosion-proof solenoid valve 12 and the second expansion valve 13, enters the second evaporator 9 of the second cold box 7, evaporates in the second cold box 7, and then passes through the second return valve 19, enters the gas-liquid separator 4 and returns to the explosion-proof compressor 3 for circulation. However, there are still the following problems in this patent:

[0004] When the compression condensing unit is used outdoors for a long time, it is very easy to be hit or eroded by wind and rain, which reduces the service life of the compression condensing unit. At the same time, it is not convenient to organize the components on the compression condensing unit during use, and it is not convenient to perform noise reduction when the compression condensing unit is working, which reduces the protection of the outdoor compression condensing unit and its use stability is not good.
