Liquid and gas collecting device for bioreactor

The utility model discloses a liquid and gas collecting device for a bioreactor. A barrel body is a sealed container; a sampling tube, a harvesting tube, a charging port and a gas outlet are formed on the upper part of the barrel body; a liquid outlet is formed in the bottom of the barrel body; a filter membrane is arranged in the tube cavity of the gas outlet, wherein the tube ports in the lower parts of the sampling tube and the harvesting tube directly reach the bottom of the barrel body. The tube ports in the lower parts of the sampling tube and the harvesting tube are directly introduced into disinfectant in the collecting barrel, so that sprayed-out steam enters a sealed waste liquor collecting barrel and is inactivated by the disinfectant in the barrel body; waste liquor is exhausted after the waste liquor collecting barrel is sterilized at high pressure. The liquid and gas collecting device for the bioreactor can be used for effectively preventing a culture solution from being leaked, so that a proble
