The gas port is connected through the tail gas pipe, and the lower end of the tail gas scrubber is connected with a lye tank. The first liquid outlet at the lower end of the lye tank is connected to the inlet of the liquid distributor at the upper end of the tail gas scrubber through the lye spray pipe, and the lye is sprayed. A lye spray pump is arranged on the pipe, and the second liquid outlet at the lower end of the lye tank is connected with the liquid inlet of the lye recovery tank through a pipeline, and the liquid outlet of the lye recovery tank is connected with the liquid inlet of the lye tank It is connected by an lye supply pipe, and an lye supply pump is arranged on the lye supply pipe.

The current fermentation tail gas purification system only removes the live bacteria in the tail gas by "spraying" in the tail gas scrubber, but cannot completely remove the live bacteria in the tail gas. The treated tail gas is directly led to the atmosphere, and a large amount of lye will be carried in the tail gas, which will pollute the environment and cause waste of lye discharge.

Utility model content:

The purpose of the utility model is to provide a coenzyme Q10 fermentation tail gas disinfection and purification system to solve the problems that the current fermentation tail gas purification system cannot effectively purify the tail gas, and the discharge tail gas carries lye, which causes lye waste and environmental pollution.

In order to solve the above technical problems, the utility model provides a coenzyme Q10 fermentation tail gas disinfection and purification system, which includes a fermentation tank, a primary gas-liquid separator, a tail gas scrubber, an lye tank, and an lye recovery tank, and the primary gas-liquid separator The exhaust port is connected to one end of the tail gas pipe, and the other end of the tail gas pipe enters and extends from the air inlet of the tail gas scrubber into the lye tank, and wherein all the parts that extend into the lye tank below the liquid level Ventilation holes are uniformly arranged on the pipe wall of the tail gas pipe.

Preferably, it also includes a secondary gas-liquid separator, the exhaust port at the top of the tail gas scrubber is connected to the inlet of the secondary gas-liquid separator through a pipeline, and the outlet of the secondary gas-liquid separator The gas port is placed in the atmosphere, and the liquid outlet of the secondary gas-liquid separator is connected with the liquid inlet of the alkali recovery tank.

The advantages of the utility model: the coenzyme Q10 fermentation tail gas disinfection and purification system provided by the utility model extends the other end of the tail gas pipe from the air inlet of the tail gas scrubber to the lye tank, and the tail gas pipe extending into the lye Ventilation holes are set on part of the pipe wall to realize the secondary removal of live bacteria carried in the fermentation tail gas by spraying and adding a water bath, and the removal effect is better; The gas-liquid separator separates the lye and recycles it into the lye recovery tank, which can effectively recycle the lye discharged with the fermentation tail gas, and prevent the lye from being discharged along with the tail gas from polluting the environment.

detailed description:

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will describe in detail with reference to the drawings and specific embodiments.

As shown in Figure 2, in the embodiment of the present utility model, provide coenzyme Q10 fermentation tail gas disinfection and purification system, it comprises fermentation tank 1, primary gas-liquid separator 2, tail gas scrubber 3, lye tank 4, lye Recovery tank 5, the outlet of fermentation tank 1 is connected to the inlet of primary gas-liquid separator 2 through pipelines, the liquid outlet of primary gas-liquid separator 2 is connected to the liquid return port of fermentation tank 1 through pipelines, and the primary gas-liquid separator 2 is exhausted The port is connected with the tail gas scrubber 3 air inlet through the tail gas pipe 6, and the tail gas pipe 6 enters from the tail gas scrubber 3 inlet and extends to the lye tank 4 connected to the lower end of the tail gas scrubber 3, and wherein it stretches into the lye Vent holes 601 are evenly provided on the pipe wall of the tail gas pipe 6 below the liquid level 401 in the tank 4, and the first liquid outlet at the lower end of the lye tank 4 passes through the liquid distributor at the upper end of the lye spray pipe 8 and the tail gas scrubber 3 The inlet is connected, and the lye spray pipe 8 is provided with an lye spray pump 9, and the exhaust port at the top of the tail gas scrubber 3 is connected with the inlet of the secondary gas-liquid separator 7 through a pipeline, and the secondary gas-liquid separator 7 The exhaust port of the gas-liquid separator 7 is connected to the liquid inlet of the lye recovery tank 5, and the second liquid outlet at the lower end of the lye tank 4 is connected to the inlet of the lye recovery tank 5.
