Description

Condenser

Technical Field

The utility model relates to a tail gas cooling device of a reactor, in particular to a condenser.

Background

In the case of microbial reactions, tail gas is generated as the microbial reactions proceed. If the tail gas contains water vapor and is directly discharged, condensed water can form in the filter element of the air filter to block the channel, so that the normal operation of the reactor is affected, even pollution is possibly caused, and uncontrollable risks are brought. The condensed water in the tail gas is returned to the reactor (such as a reaction bag), so that the water can be supplemented, the liquid level drop caused by evaporation is avoided or reduced, and the normal operation of the reaction is facilitated.

In order to avoid the harm caused by condensed water, 2 modes exist in the prior art, one is to heat an air filter and avoid steam condensation by using high temperature. The method has the advantages of poor effect, relatively complex structure, higher energy consumption and limited application range. In addition, the tail gas is cooled, so that the absolute humidity in the tail gas is reduced, and condensed water is prevented from being generated in the air filter. The traditional cooling mode has air cooling, the air cooling effect is poor, a new pollution source can be introduced into a clean factory building or the cleanliness of a clean area can be reduced, and the application range is limited. Jacket-type liquid cooling requires the introduction of tail gas into the coil to increase the heat exchange area, and such piping is also difficult to clean and also presents a risk of introducing contamination.

CN212998476U discloses an exhaust gas condensing device for a bioreactor, which is cooled by using a semiconductor refrigerating sheet, and simultaneously utilizes a heat radiating element for radiating heat of a heating side of the semiconductor refrigerating sheet. CN218120250U discloses a reactor tail gas condensing device. The tail gas condensing device of the reactor comprises a condensing tube and a refrigerating device, wherein the condensing tube is hollow, gas can enter from one end of the condensing tube and is discharged from the other end of the condensing tube, the refrigerating device is arranged on the periphery of the condensing tube, a refrigerating body is arranged in the refrigerating device, the refrigerating body is a hollow tubular semiconductor refrigerating sheet, and one refrigerating surface of the refrigerating body is attached to the outer wall of the condensing tube. Adopt the tail gas condensing equipment of reactor that this application provided can replace traditional condenser pipe that uses the condensate, can be to biological reaction tail gas condensation under the condition that does not use the condensate to possess the backward flow effect, increased condensing equipment's service scenario, simplified condensing system, make the condensation operation simplify, it is clean. The semiconductor cooling device occupies a relatively large area, an additional circuit is required to be designed, and the tail gas is required to be directly contacted with the condenser. The application of such condensers is also limited and relatively costly and is not suitable for the cooling process of disposable tail gas bags.
