Description

Technical Field

[0001] This utility model relates to the technical field of fermentation system exhaust gas treatment devices, and in particular to a fermentation system exhaust gas treatment device. Background Technology

[0002] With the widespread application of microbial fermentation technology in our lives and industrial production processes, the environmental pollution caused by the exhaust gases produced during fermentation has become a major concern. The production level of microbial fermentation mainly depends on the genetic characteristics of the microbial strains and the cultivation conditions. A large amount of air not used by the microorganisms needs to be released into the atmosphere with the exhaust gases from the fermentation tank, especially in fermentation processes primarily based on high-density liquid aerobic fermentation. During this process, a large amount of air is used, and some volatile amino acids and other metabolic products also leave the tank with the exhaust gases, accompanied by a foul odor. All of this pollutes the environment and harms human health. Therefore, the exhaust gases produced during microbial fermentation must be purified before being released into the environment.

[0003] However, in the existing technology, most of the exhaust gas treatment devices on the market are complex in structure and expensive. Moreover, due to insufficient contact between the exhaust gas and the exhaust gas treatment liquid in the exhaust gas treatment tank, the treatment effect of fermentation exhaust gas is not good, which has defects. Utility Model Content

[0004] The purpose of this invention is to address the technical problems of existing exhaust gas treatment devices, which are mostly complex in structure, expensive, and have poor treatment effect on fermentation exhaust gas due to insufficient contact between exhaust gas and exhaust gas treatment liquid in the exhaust gas treatment tank. Therefore, this invention proposes an exhaust gas treatment device for fermentation systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fermentation system exhaust gas treatment device, comprising a fermentation equipment body, a support plate fixedly connected to the upper surface of the fermentation equipment body, a cover plate fixedly connected to one side surface of the support plate, a processing dish fixedly connected to the upper surface of the support plate, a bracket fixedly connected to the upper surface of the processing dish, a motor fixedly connected to the upper surface of the bracket, three stirring plates fixedly connected to the output end of the motor, a through hole opened between the upper surface of the support plate and the bottom surface of the processing dish, a gas guide pipe connected to the bottom surface of the inner wall of the processing dish through the through hole, and multiple air holes opened on the outer surface of the gas guide pipe.

[0006] Furthermore, a liquid level window is provided on the outer surface of the processing vessel, and a transparent glass is embedded in the inner wall surface of the liquid level window.

[0007] Furthermore, a liquid level gauge is provided on the outer surface of the transparent glass.

[0008] Furthermore, a protective cover is fixedly connected to the upper surface of the bracket.

[0009] Furthermore, the outer surface of the protective cover is provided with a plurality of heat dissipation holes at equal intervals, and the plurality of heat dissipation holes are distributed at equal intervals.

[0010] Furthermore, multiple pores are equidistantly distributed.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, during use, the gas produced by fermentation is introduced into the interior of the gas guide tube through the through hole, and then discharged through multiple gas holes, coming into contact with the tail gas treatment liquid inside the processing vessel. The output end of the motor drives three stirring plates to rotate, and the three stirring plates drive the tail gas treatment liquid to flow, so that the tail gas treatment liquid and the gas come into full contact and react. During the process of the gas rising, it reacts, dissolves and is absorbed by the tail gas treatment liquid, thereby improving the treatment effect of the tail gas.

[0013] 2. In this utility model, the height of the treatment liquid and the working status of the internal parts can be observed through the transparent glass inside the liquid level window, and the tail gas treatment liquid can be repaired and replenished in a timely manner. The remaining amount of tail gas treatment liquid can be accurately read through the liquid level gauge. The protective cover prevents debris from being drawn into the output end of the motor. Multiple equidistant heat dissipation holes ensure uniform air circulation and heat dissipation of the motor. Multiple air holes evenly disperse the tail gas and ensure the treatment effect.
