In addition, it generally contains carbon dioxide, carbon monoxide, etc., while coal gas is mainly carbon monoxide. Existing exhaust gas treatment equipment generally treats one component (such as nitric oxide), and the treatment of nitric oxide gas generally adopts activated carbon adsorption or liquid absorption. The effect of these two methods alone is not ideal. In addition, exhaust gas usually contains particulate matter, which may contain other toxic components. If not treated, these substances may not only be eventually discharged, but also corrode the treatment equipment. Summary of the invention

DETAILED DESCRIPTION

[0012] As shown in the figure, this embodiment includes a body 1 and a leg installed under the body 1. In the body 1 of this embodiment, according to the gas travel, it includes a dust removal part 4, an absorption part 2, an ozone generation part 6 and an activated carbon absorption part in sequence.

[0013] according to Figure 1 In the direction shown, the dust removal part 4 and the absorption part 2 of this embodiment are located at the left end of the device, wherein the absorption part 2 is located above the dust removal part 4. A filter screen 3 is provided at the upper end of the dust removal part 4, and the filter screen 3 filters particulate matter in the gas and drops it to the bottom of the dust removal part 4. A guide groove is provided in the inner cavity of the body 1, and the filter screen 3 is inserted into the guide groove through the slot on the body 1.

[0014] The lower bottom of the dust removal part 4 is an inclined surface, and the air inlet 17 of the equipment is located at the high end of the inclined surface, and the dust discharge port 15 is arranged at the low end of the inclined surface, that is, the lower bottom is inclined from high to low from the air inlet to the dust discharge port 15. A baffle 16 is fixed on the side wall of the body 1 above the air inlet 17, and a gap is left between the baffle 16 and the lower bottom of the dust removal part. The baffle 16 is inclined, and its inclination direction is roughly the same as the direction of the lower bottom surface of the dust removal part, that is, the baffle 16 is also inclined from high to low from the air inlet side to the dust discharge port 15, but its inclination angle is greater than the inclination angle of the lower bottom of the dust removal part, thereby causing the suspended end of the baffle 16 to have a smaller distance from the lower bottom of the dust removal part 4 than the connection end thereof with the body 1, so that the baffle 16 pressurizes the gas entering from the air inlet 17, and the gas flow rate at its suspended end increases. On the one hand, the baffle 16 can prevent the particulate matter filtered out by the filter 3 from falling into the air inlet 17, and on the other hand, it can guide the particulate matter falling thereon to the dust outlet 15. Moreover, the particulate matter can be blown away in the suspended part, thereby increasing the movement speed of the particulate matter toward the dust outlet 15 and preventing the particulate matter from accumulating there and blocking the air inlet 17.

[0015] The absorption part 2 of this embodiment is equipped with absorption fillers, and the absorption fillers can be arranged according to the main components of the waste gas to be treated. For example, in the process of treating automobile exhaust gas, titanium dioxide, iron oxide, etc. can be used.

[0016] The absorption part 2 is connected to the inner cavity of the ozone generating part 6 through the first gas outlet 5 arranged at the upper part thereof. In this process, the remaining oxygen components in the treated gas are fully utilized, which plays a disinfection role on the one hand, and provides a certain amount of oxygen components for the subsequent oxidation part on the other hand. The ozone generating part 6 adopts the existing technology, which will not be described here.

[0017] The oxidizing part 7 of this embodiment adopts a spraying method, and the second gas outlet 14 for connecting the oxidizing part 7 with the ozone generating part 6 is located at the lower part of the oxidizing part 7, so that the gas can fully contact with the spraying liquid.

[0018] The activated carbon absorption part includes a first porous plate 8 and a second porous plate 12 and an activated carbon layer 9 therebetween. An inner protruding ring is provided on the inner wall of the body 1 between the oxidation part 7 and the activated carbon absorption part, and the left side of the first porous plate 8 cooperates with the inner protruding ring. A retaining ring 11 fixedly connected to the body 1 is provided on the right side of the second porous plate 12.

[0019] The right side of the activated carbon absorption part is a gas collecting chamber 9, and the main gas outlet is located at the upper end of the gas collecting chamber.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
