[0014] The present utility model will be further described below with reference to the drawings.

[0015] Please refer to Figures 1-3, the utility model relates to a volatile waste gas collection and purification device, which comprises a treatment tank 1. On the inner top side wall of the treatment tank 1, five treatment frames 13 are fixedly connected. A partition plate 14 is arranged between every two treatment frames 13. On one side wall of the treatment tank 1, a supporting sealing plate 11 is fixedly connected. The five partition plates 14 are respectively fixedly connected to the inner top of the treatment tank 1 and the top side wall of the supporting sealing plate 11. The treatment frame 13 is hollow and has filter holes on its side wall. The inside of the treatment frame 13 is filled with a catalyst. The side wall inside the top of the treatment tank 1 is detachably inlaid with an electric heating tube 15. On one side wall of the treatment tank 1 near the bottom edge, an air inlet pipe 3 is fixedly connected through. The top side wall of the section of the air inlet pipe 3 extending into the inner bottom of the treatment tank 1 is evenly and detachably connected with spray nozzles 10.

[0016] The technical effect of this solution is as follows: The gas to be treated is injected into the treatment tank 1 through the air inlet pipe 3 and evenly injected into the treatment liquid through the spray nozzles 10. The treatment liquid intercepts the solid particles contained in the gas, so as to realize the function of preliminary purification treatment. Different treatment liquids or pure water can be selected according to needs. After the solid particles and some harmful substances are purified and intercepted by the treatment liquid, the gas rises and finally enters the first treatment frame 13 through the through hole reserved by the supporting sealing plate 11. The catalyst filled in the treatment frame 13 can react and purify the remaining harmful substances in the gas. Then the gas passes through the remaining treatment frames 13 in turn to improve the purification effect. Finally, the purified gas is discharged from the exhaust pipe 6. The maximum degree of purification is achieved through one device, which can effectively reduce the amount of equipment used for purification, reduce the installation and maintenance costs and the area occupied by the equipment installation.

[0017] The inner bottom end of the treatment tank 1 is filled with treatment liquid. A guiding groove 12 is opened inside the supporting sealing plate 11. The top of the guiding groove 12 is of an open structure. A transfer pipe 4 is fixedly connected to one side wall of the treatment tank 1. One end of the transfer pipe 4 is communicated with the guiding groove 12. The other end of the transfer pipe 4 extends into the inner bottom end of the treatment tank 1. A water injection pipe 5 is fixedly connected to one side wall of the transfer pipe 4. The top side wall of the treatment tank 1 is evenly penetrated and provided with feeding ports 7. The feeding ports 7 are communicated with the inside of the treatment frame 13, and a sealing plug board is inserted into the feeding ports 7. An exhaust pipe 6 is fixedly connected to one side wall of the treatment tank 1 near the top end, and the exhaust pipe 6 extends into the inner top of the treatment tank 1. The partition plates 14 are arranged in a vertically staggered form. Four support columns 2 are fixedly connected to the bottom side wall of the treatment tank 1 near the edge. The bottom side wall of the treatment tank 1 is detachably connected with a collection tank 8. A filter plate 16 is inlaid on the inner top of the collection tank 8. A communicating pipe with a valve is arranged at the connection between the treatment tank 1 and the collection tank 8. Four rollers 9 are detachably connected to the bottom side wall of the collection tank 8.

[0018] The technical effects of this solution are as follows: By opening a guiding groove 12 in the supporting sealing plate 11 and connecting the guiding groove 12 to the bottom inside the treatment tank 1 through a transfer pipe 4, the product water generated by the contact reaction of the harmful gas and the catalyst will fall into the guiding groove 12 and then be sent into the treatment liquid through the transfer pipe 4, achieving the effect of recycling. The valve on the connecting pipe is regularly opened to inject the treatment liquid into the collection tank 8, and then new treatment liquid is supplemented through the water injection pipe 5 to ensure that the treatment liquid is in the best treatment effect. The treatment liquid falling into the collection tank 8 will be purified and then put back into use, reducing energy consumption.

[0019] Specifically, when the present utility model is in use, the air inlet pipe 3 is connected to the gas emission device, and the gas enters the treatment tank 1 along the air inlet pipe 3. The gas will be injected into the treatment liquid through the spray head 10. Due to the uniform distribution of the spray heads 10, the gas can be evenly injected into the treatment liquid, avoiding injecting all at once and affecting the treatment effect, and preventing the treatment liquid from generating large fluctuations, which may affect the stability of the treatment tank 1 itself. Moreover, the uniform distribution injection can improve the full contact and mixing of the gas and the treatment liquid, enhancing the purification treatment effect on solid waste and some harmful substances. Subsequently, the gas rises after being discharged from the treatment liquid and then enters the first treatment frame 13 through the opening reserved at one end of the supporting sealing plate 11. The treated gas is filtered through the filter holes opened on the side wall of the treatment frame 13. Finally, the gas contacts and reacts with the catalyst filled in the treatment frame 13 for the final purification treatment. Since the partition plates 14 are in an interleaved state and the positions of the reserved openings are distributed up and down, the residence time of the gas in the treatment tank 1 can be increased, thereby prolonging the reaction and purification time and improving the purification treatment effect. The top inside the treatment tank 1 is heated by the electric heating tube 15 to keep the catalyst always within the temperature range for reaction. Finally, the purified gas will be discharged from the exhaust pipe 6, and the product water generated by the reaction will flow into the treatment liquid at the bottom inside the treatment tank 1 through the guiding groove 12 and the transfer pipe 4 to achieve the replenishment of the treatment liquid. When it is necessary to supplement the catalyst, the blocking plate in the feeding port 7 can be taken out. The valve on the connecting pipe is regularly opened to inject the used treatment liquid into the collection tank 8 through the connecting pipe. The discharged treatment liquid falls into the collection tank 8 through the filter plate 16 for collection. The treatment liquid in the collection tank 8 is regularly cleaned and will be purified and then put back into use to avoid waste.

It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.

[0021] Other parts not detailed in the present utility model belong to the prior art, so they will not be elaborated here.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
