Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a wet hydrogen sulfide adsorption device. Background Art

[0002] Hydrogen sulfide is a toxic gas with a pungent and foul odor. Therefore, when the exhaust gas contains hydrogen sulfide, it is necessary to adsorb the hydrogen sulfide in the exhaust gas. The adsorption is achieved through an absorption tower. The absorption tower is composed of a tower body, a support plate, fillers, nozzles and a circulating pump. After the exhaust gas enters the tower body, the exhaust gas moves upward, passes through the fillers, and the alkaline solution at the bottom of the inner wall of the tower body is sucked upward by the circulating pump. The alkaline solution will be sprayed out from the nozzle, and the alkaline solution will fall into the filler and come into contact with hydrogen sulfide. After the alkaline solution comes into contact with the acidic hydrogen sulfide, an acid-base neutralization reaction occurs, and the acid-base neutralization reaction will generate heat. After that, the gas continues to flow upward for secondary treatment, and finally, after water vapor separation, it can go to the next process.

[0003] When hydrogen sulfide is treated through an absorption tower, the acid-base neutralization reaction will release a large amount of heat. When the heat accumulates in the filler, it will inhibit the subsequent acid-base neutralization reaction and affect the effect of hydrogen sulfide absorption. Therefore, the present application provides a wet hydrogen sulfide adsorption device to meet the needs. Utility Model Content

[0025] like Figure 1-Figure 3As shown, the embodiment of the utility model provides a wet hydrogen sulfide adsorption device, including a tower body 1 and a supporting filter plate 2, the supporting filter plate 2 is fixed to the inner wall of the tower body 1, a waterproof motor 6 is fixed to the bottom of the supporting filter plate 2, the output end of the waterproof motor 6 movably penetrates the supporting filter plate 2, a circular shaft 7 is fixed to the output end of the waterproof motor 6, a cooling rod 8 is fixed to the circumferential surface of the circular shaft 7, a curved plate 9 is fixed to the end of the cooling rod 8, an annular water tank 3 is fixed to the inner wall of the tower body 1, the curved plate 9 is close to the inner wall of the water tank and close to the circular shaft 7 on the side away from the circular shaft 7 On the side, the surface of the annular water tank 3 is connected with an inlet pipe 4 and an outlet pipe 5, which are both fixedly passed through the outer peripheral surface of the tower body 1, and the outlet pipe 5 is arranged obliquely below the inlet pipe 4. During use, cold water enters the annular water tank 3 from the inlet pipe 4, and cooling water flows out from the outlet pipe 5. The waterproof motor 6 is connected to an external controller, and the controller controls the rotation speed and start and stop of the waterproof motor 6. The cooling rod 8 is a copper tube, and a refrigerant is arranged inside the copper tube. The refrigerant is used as a heat exchange medium, and the thermal conductivity is higher.

[0026] like Figure 3 As shown, in this embodiment, a chamfer is provided at the vertical edge of the curved plate 9 close to the circular shaft 7 to reduce the impact between the curved plate 9 and the filler, thereby reducing the fluctuation of the filler.

[0027] like Figure 2 As shown, in this embodiment, a limiting ring 12 is fixed to the inner wall of the water tank and close to the circular shaft 7. There are two limiting rings 12 in total. The curved panel 9 is located between the two limiting rings 12. The limiting ring 12 limits the curved panel 9 to prevent the curved panel 9 from moving up and down, making the curved panel 9 more stable during movement.

[0028] like Figure 2 As shown, in the present embodiment, two groups of cooling rods 8 are provided, and the two groups of cooling rods 8 are symmetrically arranged about the circular axis 7. Each group of cooling rods 8 is provided with two cooling rods. A connecting plate 10 is connected between the two cooling rods 8. The connecting plate 10 increases the stability of the connection between the upper and lower cooling rods 8 and increases the overall connection strength. Secondly, the connecting plate 10 increases the contact area with the filler and increases the cooling effect on the filler.

[0029] like Figure 2 As shown, in this embodiment, there are four connecting plates 10, which are arranged in parallel with each other. The inside of the filler is cooled by the four connecting plates 10. After the four connecting plates 10 are arranged in parallel, the rotation is stable during rotation, and the connecting plates 10 will not cause the filler to have large fluctuations.

[0030] like Figure 3As shown, in this embodiment, a chamfer is provided at the vertical edge of the connecting plate 10 close to the circular shaft 7. The chamfer of the connecting plate 10 guides the filler and reduces the collision between the connecting plate 10 and the filler during rotation in the filler.

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, a scraper 11 is fixed to the circumferential surface of the circular shaft 7 near the top, and the scraper 11 is used to scrape the top of the filler to make it smooth, thereby ensuring the occurrence of internal acid-base neutralization reaction.

[0032] like Figure 2 As shown, in this embodiment, the scraper 11 is inclined, and the inclined scraper 11 can scoop up the filler, and the filler slides along the inclined surface of the scraper 11 and falls into the filler again, thereby preventing the filler from accumulating on the scraper 11.

[0033] Working principle: after the waste gas containing hydrogen sulfide gas is passed into the tower body 1, the circulation pump is started at this time, and the alkaline solution at the bottom of the inner wall of the tower body 1 is sucked upward by the circulation pump, and the alkaline solution is sprayed from the nozzle inside the tower body 1, and the alkaline solution is sprayed on the filler on the top of the supporting filter plate 2. The waste gas passes through the filler, and the hydrogen sulfide in the waste gas contacts with the alkaline solution and an acid-base neutralization reaction occurs. During the reaction, the heat released will be transferred to the filler;

[0034] During the reaction, cold water is introduced into the annular water tank 3 through the water inlet pipe 4, and the cold water is discharged from the water outlet pipe 5. At this time, the cold water cools the annular water tank 3, and the surface temperature of the annular water tank 3 is reduced, and the filler is cooled through the annular water tank 3. Secondly, the waterproof motor 6 rotates, and the waterproof motor 6 drives the circular shaft 7 to rotate clockwise, and the circular shaft 7 drives the cooling rod 8 to rotate clockwise, and the cooling rod 8 drives the curved plate 9 to slide slowly on the inner wall of the annular water tank 3, and the annular water tank 3 cools the curved plate 9, and the curved plate 9 cools the cooling rod 8. The cooling rod 8 stirs inside the filler, thereby cooling the inside of the filler and improving the cooling effect. Secondly, the cooling rod 8 cools the connecting plate 10, further increasing the cooling area, improving the cooling effect, and avoiding the inhibition of the neutralization reaction inside the filler;

[0035] The circular shaft 7 is rotating, and the circular shaft 7 drives the scraper 11 to rotate, and the top of the filler is scraped flat by the scraper 11.

[0036] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
