[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Combined with Figure 1 To Attachment Figure 5 A small-sized waste gas treatment device comprises a base frame 1 and a box body 2 fixedly arranged on the upper end surface of the base frame 1, an air inlet 3 is arranged at the left end of the box body 2, an electrostatic dust removal device is arranged near the air inlet 3 inside the box body 2, a photocatalyst sterilization mechanism is fixedly arranged on the right side of the electrostatic dust removal device, a partition 4 is fixedly arranged on the right side of the photocatalyst sterilization mechanism, the partition 4 separates the internal space of the box body 2 into a closed chemical treatment chamber 5, a medicine box 6 is fixedly arranged inside the chemical treatment chamber 5, an air pump 7 is fixedly arranged on the side of the medicine box 6, an air inlet end of the air pump 7 passes through the partition 4 and is connected with the chamber on the left side of the partition 4, an air outlet end of the air pump 7 extends into the inside of the medicine box 6 and is immersed below the liquid level of the medicine, an air outlet 8 is arranged at the upper end of the medicine box 6 and a medicine outlet 9 is arranged at the bottom.

[0025] In this embodiment, the electrostatic precipitator includes a needle-shaped cathode 10 fixedly arranged inside the air inlet 3, and also includes a vertical plate 11 fixedly arranged inside the box 2, and an anode plate 12 is fixedly arranged on the side of the vertical plate 11 close to the air inlet 3. A gap 13 for exhaust gas to pass through is left between the upper end of the vertical plate 11 and the top surface of the box 1. A dust cleaning port 14 is provided on the bottom surface of the box 2 and directly below the anode plate 12.

[0026] In this embodiment, the photocatalyst sterilization mechanism includes a plurality of transparent screens 15 fixedly arranged inside the box body 2 , the surface of the transparent screens 15 is coated with a nano titanium dioxide coating, and an ultraviolet lamp 16 is fixedly arranged on the inner wall of the box body 2 .

[0027] Before using the utility model, first connect the external power supply, the whole process steps of the exhaust gas treatment device are as follows:

[0028] 1. Exhaust gas enters the device: Exhaust gas enters the interior of the box 2 through the air inlet 3 of the device.

[0029] 2. Electrostatic precipitator: After the exhaust gas enters the box, it first passes through the electrostatic precipitator. Near the air inlet, the dust particles in the exhaust gas are first charged by the needle-shaped cathodes 10. These cathodes release electrons under the action of high voltage, causing the dust particles passing through to be negatively charged. Then, these charged dust particles are attracted by the anode plates 12 near the air inlet side, which are supported and fixed by the vertical plates 11. The anode plates collect and capture these negatively charged dust particles, thereby separating them from the air flow. In this way, most of the solid particles are effectively separated, and the purified gas continues to flow downward into the next step of the treatment process.

[0030] 3. Photocatalytic sterilization: The waste gas after electrostatic dust removal continues to flow to the photocatalytic sterilization mechanism. The surface of the multiple transparent mesh plates 15 here is coated with a nano titanium dioxide coating. When the waste gas passes through, the ultraviolet lamp 16 irradiates the titanium dioxide, generating a photocatalytic reaction, effectively killing pathogens (such as bacteria, viruses, etc.) in the waste gas, thereby purifying the waste gas.

[0031] 4. Chemical treatment: The purified waste gas continues to flow to the chemical treatment chamber 5. In this closed space, the waste gas contacts the chemical reagent in the reagent box 6. The vacuum pump 7 sends the waste gas into the reagent, and the waste gas passes through the vacuum pump outlet end submerged in the reagent liquid level and reacts with the chemical reagent.

[0032] 5. Exhaust gas treatment is completed: the exhaust gas fully contacts and reacts with the reagent inside the reagent box 6 to achieve a purification effect. The exhaust gas is finally discharged through the air outlet 8 of the box, and the reagent is discharged from the reagent outlet 9 after use.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
