DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] A multi-cycle process gas condensation purification system comprises a condenser 1, a thermal temperature controller 2, a purifier 3 and a liquid nitrogen source 4. The condenser 1 comprises a main body tube 5, which is divided into an air cooling section 6 and a liquid cooling section 7. The liquid cooling section 7 is located below the air cooling section 6, and a coolant 8 is arranged in the liquid cooling section 7. An air cooling partition 9 is arranged inside the air cooling section 6, and the air cooling partition 9 divides the air cooling section 6 into an air cooling chamber 1 10 and an air cooling chamber 2 11. The bottom of the air cooling partition 9 is flush with the liquid surface of the coolant 8. Three left heat exchange tubes 12 are arranged inside the air cooling chamber 1 10, and a condensation air inlet pipe 2 13 is commonly connected to the tops of the three left heat exchange tubes 12, and a condensation air outlet pipe 2 13 is commonly connected to the bottoms of the three left heat exchange tubes 12, and the condensation air outlet pipe 2 13 is located at the liquid cooling section 7. Three right heat exchange tubes 14 are arranged inside the air cooling chamber 2 11, and the tops of the three right heat exchange tubes 14 are commonly connected to the condensation air inlet pipe 3 15, and the bottoms of the three right heat exchange tubes 14 are commonly connected to the condensation air outlet pipe 3 15, and the condensation air outlet pipe 3 15 is located at the liquid cooling section 7. In order to enhance the heat exchange efficiency of the left heat exchange tube 12 and the right heat exchange tube 14, the left heat exchange tube 12 and the right heat exchange tube 14 are both in the shape of spiral tubes. The condensation air outlet pipe 1 16 and the condensate air inlet pipe 2 13 are respectively connected to the front end and the rear end of the purifier 3, and the liquid nitrogen source 4 and the condensation air inlet pipe 3 15 are respectively connected to the front end and the rear end of the purifier 3. In order to control the temperature, a thermal temperature controller 2 is provided at the connection passage between the purifier 3 and the condensate air inlet pipe 2 13, and a thermal temperature controller 2 is provided at the connection passage between the purifier 3 and the condensate air inlet pipe 3 15.

[0019] A condensation air inlet pipe 18 is provided at the lower part of the side wall of the air-cooling chamber 10, and a condensation air outlet pipe 16 is provided at the upper part of the side wall of the air-cooling chamber 2 11. Industrial gas is introduced from the condensation air inlet pipe 17. After the air pressure in the air-cooling chamber 10 reaches a certain value, the industrial gas escapes from the air-cooling chamber 10 to the air-cooling chamber 2 11 through the coolant. In this process, the industrial gas will be pre-cooled by the coolant 8, and after entering the air-cooling chamber 2 11, it will be further pre-cooled by three right heat exchange tubes 14 inside the air-cooling chamber 2 11. After the industrial gas is pre-cooled by the condenser 1, it is exported to the purifier 3 through the condensation air outlet pipe 16. The purifier 3 performs a purification operation on the industrial gas. In this process, the liquid nitrogen source 4 connected to the purifier 3 outputs liquid nitrogen to the purifier 3, and the liquid nitrogen is used to further reduce the temperature of the industrial gas and promote the purification reaction. Further, the liquid nitrogen passing through the purifier 3 is transmitted to the three right heat exchange tubes 14 of the condenser 1, the upper part of the right heat exchange tube 14 is located in the air cooling chamber 2 11, and the lower part of the right heat exchange tube 14 is located in the liquid cooling section 7. The right heat exchange tube 14 located in the air cooling chamber 2 11 can pre-cool the industrial gas entering the purifier 3, and the right heat exchange tube 14 located in the liquid cooling section 7 can reduce the temperature of the coolant 8. The temperature of the industrial gas purified by the purifier 3 is relatively low, and the temperature is increased by the thermal temperature controller 2 and the condenser 1. After the industrial gas with a relatively low temperature enters the air cooling chamber 10 through the left heat exchange tube 12, the industrial gas in the air cooling chamber 10 is pre-cooled. Further, the industrial gas in the left heat exchange tube 12 exchanges heat with the coolant 8 in the liquid cooling section 7, and finally the warm purified industrial gas is discharged from the condensation outlet pipe 2 13.
