Description

Technical Field

[0001] This utility model relates to the technical field of acid mist absorption equipment, specifically an acid mist absorber. Background Technology

[0002] The acid mist absorber mainly treats harmful gases such as hydrogen chloride (HCl) gas, hydrogen fluoride (HF) gas, acid mist (H2SO4), chromic acid mist (CrO3), hydrogen cyanide (HCN) gas, hydrogen sulfide (H2S), ammonia (NH3), and alkaline vapors, which are water-soluble gases.

[0003] Currently, acid mist absorbers are generally used for the neutralization of acid mist. However, during the gas-liquid neutralization process, particles in the exhaust gas are directly carried to the bottom of the cylinder and discharged together. An external filtration device is required to filter impurities, which increases the cost of equipment and pipelines. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide an acid mist absorber to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an acid mist absorber, comprising a main cylinder, an enclosing cylinder, a top cover, and a water inlet pipe. The enclosing cylinder is arranged around the bottom of the main cylinder. Several through holes are provided at the connection between the bottom of the main cylinder and the enclosing cylinder. A top cover is provided at the top of the main cylinder. A lower support and an upper support are provided on the inner wall of the main cylinder. A support ring is provided on the upper surface of the lower support. A filter screen is provided on the upper surface of the support ring. A perforated plate is provided on the upper surface of the upper support. An air inlet and a viewing window are provided on the main cylinder between the lower support and the upper support. An air outlet is provided on the upper surface of the top cover. A water inlet pipe is mounted on the upper part of the main cylinder.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an acid mist absorber, including a main cylinder 1, an enclosing cylinder 2, a top cover 3, and a water inlet pipe 4. The enclosing cylinder 2 is arranged around the bottom of the main cylinder 1. Both the main cylinder 1 and the enclosing cylinder 2 have a bottom plate 19 at their bottoms. Several fixing plates 20 are arranged around the bottom plate 19 to achieve overall support and fixation. A drain port 18 is provided on one side of the enclosing cylinder 2. When the spray liquid passes through the perforated plate 10 and the filter screen 9, it flows into the bottom of the main cylinder 1 and the enclosing cylinder 2, and then is discharged through the drain port 18. Several through holes 5 are provided at the connection between the bottom of the main cylinder 1 and the enclosing cylinder 2. A top cover 3 is provided at the top of the main cylinder 1. A gasket 23 is provided at the connection between the top cover 3 and the main cylinder 1 to ensure the sealing of the top cover 3. A lower support 6 and an upper support 7 are provided on the inner wall of the main cylinder 1. A support ring 8 is provided on the upper surface of the lower support 6, and a filter screen 9 is provided on the upper surface of the support ring 8. The upper surface of the upper support 7 is provided with a perforated plate 10. The main cylinder 1 is filled with PP multifaceted hollow spheres 17. The PP multifaceted hollow spheres 17 are stacked on the upper surface of the perforated plate 10 to increase the gas-liquid contact area and adsorb harmful substances. The main cylinder 1 is located between the lower support 6 and the upper support 7 and is provided with an air inlet 11 and a viewing window 12. The upper surface of the top cover 3 is provided with an air outlet 13. The upper end of the main cylinder 1 is provided with a water inlet pipe 4. One end of the water inlet pipe 4 is connected to the water inlet 15 through a connecting sleeve 14. The inner wall of the upper part of the main cylinder 1 is provided with a bracket 21. The end of the water inlet pipe 4 away from the connecting sleeve 14 is provided with an extension bracket 22. The extension bracket 22 is fastened to the bracket 21 by bolts and nuts, thereby realizing the installation and fixation of the water inlet pipe 4. The water inlet 15 is provided through the side wall of the main cylinder 1. Several nozzles 16 are provided on the lower surface of the water inlet pipe 4.

[0023] like Figure 5As shown, the viewing window 12 includes a cylindrical base 1201 and a viewing cover 1202. The cylindrical base 1201 is connected to the main cylinder 1, and the viewing cover 1202 is fastened to the cylindrical base 1201 by bolts. The viewing window 12 with this structure allows for observation of impurities on the filter screen 9 inside the main cylinder 1, and also allows for cleaning of the filter screen 9 by opening the viewing cover 1202. The viewing cover 1202 can be a ring or a fiberglass structure.

[0024] Installation method and operating principle: First, place the support ring 8 with the filter screen 9 vertically from the top into the main cylinder 1, passing through the upper support 7, and then lay the support ring 8 flat, supporting it on the lower support 6. Next, place the perforated plate 10 vertically from the top into the main cylinder 1, reaching the upper support 7, and then lay the perforated plate 10 flat, supporting it on the upper support 7. Then, place the water inlet pipe 4 into the main cylinder 1, and secure one end of the water inlet pipe 4 to the bracket 21 via the extension frame 22 and bolts and nuts. The other end of the water inlet pipe 4 is connected to the extension section of the water inlet 15 via the connecting sleeve 14. Pour the PP multi-faceted hollow spheres 17 into the main cylinder 1 and stack them on the perforated plate 10 for support. Finally, connect the top cover to the top of the main cylinder 1 via bolts and nuts to complete the installation. During operation, acid mist enters the main cylinder 1 through the air inlet 11, while the neutralizing spray liquid enters the water inlet pipe 4 through the water inlet 15 and is then injected into the main cylinder 1 through the nozzle 16 on the lower surface of the water inlet pipe 4, where vapor and liquid mix, thereby achieving a clean exhaust gas effect. The particles in the acid mist, after being sprayed with the neutralizing liquid, are filtered and trapped on the filter screen 9, while the liquid flows through the filter screen 9 to the bottom of the main cylinder 1, then flows into the surrounding cylinder 2 through the through-hole 5 and is discharged from the drain port 18. This utility model has a reasonable structure. Inside the main cylinder 1, a perforated plate 10 is installed via an upper support 7. Inside the main cylinder 1, below the perforated plate 10, a filter screen 9 is installed via a lower support 6. When acid mist is sprayed, particles in the acid mist can be intercepted by the filter screen 9, thereby greatly reducing the content of particulate impurities in the waste liquid, which facilitates further treatment of the waste liquid and saves the cost of setting up an additional filtration device. At the same time, a viewing window 12 is also provided in the main cylinder 1 between the lower support 6 and the upper support 7. The viewing window 12 facilitates observation of the internal working status of the equipment and also facilitates cleaning of the filter screen 9.
