Gas-liquid separator

Abstract

The invention relates to the technical field of biological aerobic fermentation, in particular to a gas-liquid separating device which is used in a production process with biological aerobic fermentation and comprises at least two serially-connected monomer type separators. The gas-liquid separating device adopts two-level or multilevel separators, thus effectively realizing gas and liquid separation, reducing the usage of foam killers, and improving tank capacity rate; furthermore, the gas-liquid separating device lowers production cost and directly leads to economic benefits. The gas-liquid separating device reduces the discharge of harmful substances, improves environment-protecting efficiency, raises the product purity, lowers the consistency of feed liquid and has favorable extraction. The gas-liquid separating device effectively prevents the phenomenon of liquid leakage and tank overflow, greatly reduces loss, and lowers the labor intensity of operators.

Description

technical field [0001] The invention relates to the technical field of biological aerobic fermentation, in particular to a gas-liquid separation device used in the production process of biological aerobic fermentation. Background technique [0002] During the biological aerobic fermentation production process of amino acids, organic acids, enzyme preparations, antibiotics, etc., a large amount of foam will inevitably be generated. These foams must be removed, otherwise the production will be seriously affected, or even stopped, causing a lot of losses to the enterprise. For a long time, the defoaming method used has always been chemical reagents (foaming enemy) or mixed vegetable oil, and this defoaming method is not only expensive and complicated to operate, but also pollutes products and even pollutes the environment, which adds huge production costs to enterprises and pollution control costs. [0003] The Chinese patent that the patent No. is ZL99247539.2 discloses a foa...

[0002] During the biological aerobic fermentation production process of amino acids, organic acids, enzyme preparations, antibiotics, etc., a large amount of foam will inevitably be generated. These foams must be removed, otherwise it will seriously affect production, or even stop production, causing a lot of losses to the enterprise

For a long time, the defoaming method used has always been chemical reagents (foaming enemy) or mixed vegetable oil, and this defoaming method is not only expensive and complicated to operate, but also pollutes products and even pollutes the environment, which adds huge production costs to enterprises and pollution control costs

[0003] The Chinese patent that the patent No. is ZL99247539.2 discloses a foam swallowing machine, and the Chinese patent application number 200610152773.7 discloses a foam swallowing machine automatically. There are the following defects, the saving of defoamer has not yet reached 100%, and the utilization rate of the tank capacity has not reached the limit
