One side of the filter assembly 17 is connected to the other end of the connecting pipe 18.

[0043] The working principle of the condenser-reflux device for tert-carbonic acid distillation provided by this utility model is as follows:

[0044] A connecting pipe 18 is installed at the bottom of the condenser 10. Then, a connecting plate 24 with multiple gas nozzles 23 is installed at the top of the connecting pipe 18, with the nozzles 23 facing downwards towards the distillation hopper 20. Gas is then expelled through the nozzles 23 to ensure better contact between the gas and the distillation hopper 20.

Cold water is placed inside the distillation hopper 20 to continuously cool it. A water receiving hopper 21 with a return pipe 14 is installed above the connecting plate 24 via a fixing bracket 22, positioned in the middle below the distillation hopper 20. The condensed liquid can be collected and discharged through the return pipe 14 for reflux or subsequent treatment. In actual use, the cold water inside the water tank 13 is first transported to the inside of the distillation hopper 20 through the conveying component 7. After the water inside the distillation hopper 20 reaches a certain level, it is discharged through the discharge pipe 25, thereby allowing the cold water to circulate and maintain the temperature of the distillation hopper 20. Then, the distilled carbonic acid gas is filtered through the filter component 17 and sprayed out through the gas nozzle 23, allowing the gas to contact the bottom of the distillation hopper 20. The hot vapor will liquefy and adhere to the bottom of the distillation hopper 20 when it encounters cold air. Then, it falls from the bottom tip of the distillation hopper 20 into the inside of the water receiving hopper 21 and is discharged through the return pipe 14.

[0045] Compared with related technologies, the condenser reflux device for tert-carbonic acid distillation provided by this utility model has the following beneficial effects:

[0046] To improve the condensation efficiency during tertiary carbonic acid distillation, a connecting pipe 18 is installed at the bottom of the condenser 10. Then, a connecting plate 24 with multiple nozzles 23 is installed at the top of the connecting pipe 18, with the nozzles 23 facing downwards towards the distillation hopper 20. Gas is then expelled through the nozzles 23 to improve gas contact with the distillation hopper 20. The distillation hopper 20 with a sealing ring 11 is then installed above the condenser 10 via a sealing ring 19. Cold water is placed inside the distillation hopper 20 to continuously cool it. Above the connecting plate 24, a water receiving hopper 21 with a reflux pipe 14 is installed via a fixing bracket 22, positioned in the middle below the distillation hopper 20. This allows the condensed liquid to be collected and discharged through the reflux pipe 14 for reflux or further processing.
