Gas-liquid separator of fermentation tank

Abstract

The invention provides a gas-liquid separator of a fermentation tank and solves the problem that the yield of the fermented products is influenced caused because the small water droplets in the tail gas of the fermentation tank cannot be separated when a cyclone separator is used in the existing fermentation tank. The gas-liquid separator of the fermentation tank comprises a shell, wherein the lower part of the shell is a conical structure which is gradually narrowed from top to bottom; a gas inlet is formed in the bottom of the shell; a gas outlet is formed in the top of the shell; a first collection type water distributor and a second collection type water distributor are successively arranged in the shell along the gas inlet direction and are located above the conical structure; the first collection type water distributor is used for eliminating bubbles in the tail gas of the fermentation tank; the second collection type water distributor is used for collecting the water droplets inthe tail gas of the fermentation tank; an annular liquid collection tank is mounted on the inner wall of the shell located under the second collection type water distributor along the circumferentialdirection and is used for collecting liquid flowing down from the second collection type water distributor; the bottom of the annular liquid collection tank is connected with one end of a flow returning pipe; the flow returning pipe is used for feeding the liquid in the annular liquid collection tank back to the fermentation tank.

Description

technical field [0001] The invention relates to the field of biological fermentation equipment, in particular to a device for recovering active components from the tail gas discharge of a fermentation tank, in particular to a gas-liquid separator for a fermentation tank. Background technique [0002] With the rapid development of the domestic fermentation industry in recent years, the bio-fermentation industry has become more and more important in the entire real economy, but fermentation companies have always appeared in the face of "heavy energy consumption and low output" in the past. In order to get rid of the hat of "heavy energy consumption and low output", on the one hand, a large number of energy-saving measures and energy-saving devices should be adopted in the process, and on the other hand, new processes and new technologies should be adopted to increase the yield of fermentation. [0003] In the aerobic fermentation process, it is necessary to continuously send c...
