One end of the filter 20 is connected to the outlet of the condenser 10, and the other end is an exhaust port 22. The filter 20 is used to filter the exhaust gas. The pressure sensor 30 is connected between the filter 20 and the condenser 10 to detect the pressure of the filter 20.

[0040] The exhaust gas device for the bioreactor in this embodiment uses a condenser container 10 installed between the bioreactor 200 and the filter 20. This allows the exhaust gas to pass through the condenser container 10 first during discharge, condensing some water vapor into liquid water and collecting and storing it within the condenser container 10. Finally, the gas is filtered and discharged through the filter 20, improving the clogging situation of the filter 20 and increasing the exhaust efficiency of the bioreactor 200. Furthermore, a pressure detection device 30 is installed before the filter 20 to detect the pressure inside the filter 20, preventing excessive internal pressure caused by filter 20 failure or clogging that could lead to bioreactor failure. This facilitates monitoring and rapid maintenance of the exhaust gas device by operators, improving its reliability.
