[0002] In pharmacological, toxicological, and environmental science research, animal exposure experiments are a common scientific experimental method used to evaluate the effects of chemical substances, biological agents, or other environmental factors on animal health. These experiments usually require strict control of the animal's exposure route, dose, and time to simulate the exposure situation of humans or animals in the natural environment. In particular, nose-and-mouth exposure experiments provide an accurate control method for inhalation exposure only through the respiratory tract by simulating the process of humans inhaling gases, particulate matter, or chemical substances in the natural environment, avoiding the influence of non-respiratory routes such as trans-esophageal absorption that may be brought about by other poisoning methods.

[0003] During nose-and-mouth exposure experiments, animals (such as mice, rats, etc.) inhale air containing specific chemical substances and produce waste gas. These waste gases may contain harmful chemical substances that have not been fully absorbed by the animals, so they must be effectively treated before being discharged into the environment.

[0004] The current technical defects and deficiencies in the waste gas treatment technology of animal nose-and-mouth exposure towers are as follows: In some manufacturers' exposure systems, the waste gas treatment is insufficient, there is no strong exhaust fan in the waste gas treatment module, the waste gas treatment module mostly adopts a single-stage treatment scheme, the main components of the waste gas discharged from the exposure tower are not subdivided, the volume of the waste gas treatment unit is large, the weight is high, the production cost is high, the assembly and maintenance operations are relatively complicated, the traditional control system cannot cope with complex systems, the accuracy is limited, the scalability is poor, the waste gas treatment passage is large, the resistance is large, the efficiency is low, and due to excessive aerosol residues in this passage, the filter life is reduced, and the pipeline and other accessories are corroded. Therefore, a waste gas treatment component in an exposure tower is proposed to solve the above problems. Content of the Utility Model

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

An efficient filter 2 is arranged inside the efficient fixing frame 1. An intake hood 4 for waste gas treatment inside the tower and a gas collection mounting seat 7 are respectively fixedly connected to the outer surface of the efficient fixing frame 1. A forward-inclined centrifugal separator 5 is fixedly connected to the gas collection mounting seat 7. The gas collection mounting seat 7 is connected to a control unit 8 through a downstream pressure acquisition conduit 15. An upstream pressure acquisition conduit 14 is connected between the intake hood 4 for waste gas treatment inside the tower and the control unit 8. A first activated alumina drying ball box 17 and a second activated alumina drying ball box 18 are arranged inside the efficient filter 2.

[0028] Specifically, the connecting pipe on the intake hood 4 for waste gas treatment inside the tower is connected to the waste gas exhaust interface at the bottom of the exposure tower through a corrugated pipe.

Through the forward-inclined centrifugal separator 5, the first activated alumina drying ball box 17 and the second activated alumina drying ball box 18, multiple waste gas treatment and filtration are carried out, and the harmful substances that cannot be treated are adsorbed multiple times and fully oxidized. By setting the control unit 8 and using an intelligent integrated control system, it has high control precision, strong adaptability, good scalability, low maintenance cost, fast communication speed, and strong anti-interference ability.

[0029] Specifically, the gas collection mounting seat 7 is fixedly connected to the forward-inclined centrifugal separator 5 through a handle screw 6. A transfer interface 11 is provided on the forward-inclined centrifugal separator 5. By using the handle screw 6, it is simple and fast to tighten or loosen the screw, without the need for additional tools, saving time and cost, and can reduce the harm caused by improper use of tools, improving safety.

[0030] Specifically, two hinge joints 12 are connected to the efficient fixing frame 1. The other side of the hinge joint 12 is connected to the outer surface of the intake hood 4 for waste gas treatment inside the tower. By using the hinge joint 12, the efficient fixing frame 1 and the intake hood 4 for waste gas treatment inside the tower can freely rotate at two pivot points, providing a larger range of motion and flexibility for the efficient fixing frame 1 and the intake hood 4 for waste gas treatment inside the tower.

[0031] Specifically, two buckles 3 are connected to the efficient fixing frame 1.

[0034] During implementation, the operation is carried out in the following steps: First, the connecting pipe on the intake hood 4 for waste gas treatment in the tower is connected to the waste gas exhaust interface at the bottom of the exposed tower through an external corrugated pipe.
