[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, a waste gas treatment device for a pathological tissue staining machine includes a housing 2. A corrugated pipe is provided on the right side of the housing 2 and communicates with the body 1 of the pathological tissue staining machine. An exhaust port 202 and an air inlet 201 are respectively opened on the left and right sides of the housing 2. The air inlet 201 communicates with the interior of the body 1 of the pathological tissue staining machine. From right to left, a primary filter chamber 203, a chemical filter chamber 204, and a light filter chamber 205 are arranged in the housing 2 and communicate with each other. A primary filter component, a chemical filter component, and a light filter component are respectively arranged in the primary filter chamber 203, the chemical filter chamber 204, and the light filter chamber 205. The primary filter chamber 203 and the light filter chamber 205 are respectively communicated with the air inlet 201 and the exhaust port 202. An intake fan 3 and an exhaust fan 14 are respectively installed on the air inlet 201 and the exhaust port 202 by bolts.

[0019] During use, the inlet fan 3 draws the exhaust gas from the main body 1 of the pathology tissue staining machine into the housing 1. The exhaust gas first passes through the primary filter chamber 203, where the primary filter components remove particulate matter and droplets. Then, the exhaust gas enters the chemical filter chamber 204 at the lower end of the primary filter chamber 203, where the chemical filter components neutralize and absorb harmful gases such as formaldehyde, further reducing the harm to the environment and human health. Next, the exhaust gas enters the optical filter chamber 205, where the optical filter components decompose residual organic pollutants to ensure effective treatment. Finally, the exhaust fan 14 discharges the treated exhaust gas through the exhaust port 202. Through multi-stage filtration, harmful substances in the exhaust gas are removed, significantly reducing pollution to workers and the environment, and improving the environmental performance of the pathology tissue staining machine.

[0020] In this embodiment, the primary filtration assembly includes a first filter frame 4 and a second filter frame 5 that are slidably and sealed within the primary filtration chamber 203. The second filter frame 5 is located below the first filter frame 4, and both the first filter frame 4 and the second filter frame 5 have air holes. The first filter frame 4 is filled with glass fiber, and the second filter frame 5 is filled with activated carbon. The second filter frame 5 is connected to the chemical filtration chamber 204 at its lower part. During use, the exhaust gas passes through the first filter frame 4 and the second filter frame 5 sequentially under the action of the inlet fan 3 and the exhaust fan 14. The glass fiber and activated carbon in the first filter frame 4 and the second filter frame 5 respectively filter large particulate impurities, droplets, and volatile organic compounds in the exhaust gas, thereby initially reducing the harm of the exhaust gas to workers and the environment.

[0021] In this embodiment, the chemical filtration assembly includes a storage pipe 8 fixed to the upper side of the chemical filtration chamber 204 by bolts and a plurality of atomizing nozzles 9 threadedly connected to the delivery pipe 8. A storage chamber 206 is provided below the chemical filtration chamber 204, and the lower side of the chemical filtration chamber 204 is connected to the storage chamber 206. A water pump 10 connected to the delivery pipe 8 is installed on the upper side of the housing 2 by bolts. A return pipe 11 connected to the storage chamber 206 is provided at the other end of the water pump 10. The storage chamber 206 is filled with sodium hydroxide solution. In use, the water pump 10 draws sodium hydroxide solution from the storage chamber 206 and delivers it to the storage pipe 8. Under the action of the atomizing nozzles 9, the sodium hydroxide solution is atomized and sprayed out to neutralize the chemical components in the exhaust gas in the chemical filtration chamber 204, reduce the acidity and alkalinity of the exhaust gas, and thus reduce the pollution of the exhaust gas to the environment.

[0022] In this embodiment, an inlet pipe 16 and a drain pipe 17 are provided on the right side of the liquid storage chamber 206. A valve 18 is provided on both the inlet pipe 16 and the drain pipe 17. The inlet pipe 16 is located above the drain pipe 17. During use, the operator can replace and replenish the sodium hydroxide solution in the liquid storage chamber 206 through the inlet pipe 16 and the drain pipe 17 to ensure the filtration effect of the chemical filter assembly on the exhaust gas.

[0023] In this embodiment, an air passage is provided between the chemical filter chamber 204 and the optical filter chamber 205 so that the upper end of the chemical filter chamber 204 is connected to the lower end of the optical filter chamber 205. In use, the exhaust gas in the chemical filter chamber 204 is filtered by the chemical filter component and then enters the lower end of the optical filter chamber 205 through the air passage, ensuring the filtration sequence of the exhaust gas in the exhaust gas treatment device.

[0024] In this embodiment, the light filtering assembly includes a honeycomb ceramic 12 fixed in the light filtering cavity 205 by bolts and an ultraviolet lamp 13 disposed on the upper side of the light filtering cavity 205. A titanium dioxide layer is disposed on the inner side of the honeycomb ceramic 12. The titanium dioxide layer is formed by spraying on the inner side of the honeycomb ceramic 12. In use, titanium dioxide is a photooxidant. Under the action of the ultraviolet lamp 13, it reacts with the organic pollutants in the exhaust gas and decomposes them into carbon dioxide and water. This effectively treats the gaseous pollutants generated by the pathological tissue staining machine, ensures that the exhaust gas meets environmental protection requirements, and protects the health of laboratory staff and the environment.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
