Description

Technical Field

[0001] The present application relates to the technical field of acid mist recovery, and in particular to an acid mist purification and recovery device. Background Art

[0002] Acid mist refers to mist-like acid substances. In the air, the particles of acid mist are very small, smaller than those of water mist and with a higher humidity than smoke. The particle size is 0.1 - 10 μm, which is a substance between flue gas and water mist and has strong corrosiveness. Therefore, an acid mist purification and recovery device is needed for purification and recovery treatment. Most of the existing acid mist purification and recovery devices are provided with a spraying component inside. When the acid mist is introduced into the purification and recovery device, it is combined with the alkali liquid sprayed by the spraying component to achieve the purification effect. However, in this process, the acid mist is not dispersed and only sprayed once, making it difficult for the spraying component to completely spray the flowing acid mist. Utility Model Content

[0003] In order to solve the problems of not dispersing the acid mist and only spraying the acid mist once, making it difficult for the spraying component to completely spray the flowing acid mist, the present application provides an acid mist purification and recovery device.

Detailed Embodiments

[0015] The following further elaborates on the present application in conjunction with the attached Figure 1-4 for a more detailed description.

[0016] The embodiment of the present application discloses an acid mist purification and recovery device. Refer to Figure 1-4, including a support 11 and a recovery tank 12. The recovery tank 12 is fixedly installed at the top of the support 11. The support 11 can support the recovery tank 12. A treatment tank 13 is fixedly installed at the top of the recovery tank 12. The treatment tank 13 can be used to treat acid mist. The treatment tank 13 is communicated with the recovery tank 12 through a connecting pipe 17. The liquid in the treatment tank 13 can flow into the interior of the recovery tank 12 through the connecting pipe 17. A tank cover 14 is movably sleeved on the top of the treatment tank 13. The tank cover 14 can seal the top of the treatment tank 13. Fixed components 2 for limiting the tank cover 14 are arranged on both sides of the treatment tank 13. The fixed components 2 are composed of a plug rod 21, a U-shaped limiting block 22, and a screw 23. The plug rod 21 is fixedly connected to the outer side wall of the tank cover 14. The U-shaped limiting block 22 is fixedly connected to the outer side wall of the treatment tank 13. The plug rod 21 movably penetrates through the U-shaped limiting block 22. One end of the screw 23 threadedly penetrates through the U-shaped limiting block 22, and one end of the screw 23 is threadedly connected to the U-shaped limiting block 22, so that the tank cover 14 can be fixed at the top of the treatment tank 13 and cannot move. A water collecting groove is opened at the top of the tank cover 14. A sealing ring 15 for sealing the water collecting groove is fixedly installed at the top of the tank cover 14. One end of the top of the sealing ring 15 is fixedly penetrated by a liquid injection pipe 16. Through the liquid injection pipe 16, an external alkaline solution can be discharged into the interior of the water collecting groove. A mist discharge pipe 3 is fixedly connected to the middle of the top of the tank cover 14, and the mist discharge pipe 3 is in communication with the treatment tank 13. After one end of the mist discharge pipe 3 is communicated with the mist discharge port of an external chemical treatment device, the mist discharge pipe 3 can discharge acid mist into the interior of the treatment tank 13 for treatment. A water bath net one 41 and a water bath net two 42 are fixedly connected to the bottom end of the tank cover 14. The water bath net one 41 is located inside the water bath net two 42. Both the water bath net one 41 and the water bath net two 42 are made of stainless steel, which is acid and alkali resistant. The bottom ends of the water bath net one 41 and the water bath net two 42 are both in contact with the inner bottom wall of the treatment tank 13. When the acid mist passes through the filter holes of the water bath net one 41 and the water bath net two 42, the water bath net one 41 and the water bath net two 42 cooperate to disperse the acid mist and filter the impurities in the acid mist at the same time. Two groups of annularly distributed atomizing nozzles 43 are fixedly penetrated through the inner bottom wall of the water collecting groove. Each group of atomizing nozzles 43 has several. The distances between any two of the several atomizing nozzles 43 in each group are the same. When the two groups of atomizing nozzles 43 atomize and spray the alkaline solution onto the outer surfaces of the water bath net one 41 and the water bath net two 42, a water film will be formed. When the acid mist passes through the filter holes of the water bath net one 41 and the water bath net two 42, the acid mist will come into full contact with the alkaline liquid water film, so that it can be fully neutralized. The neutralized liquid finally flows into the interior of the recovery tank 12 through the connecting pipe 17 and is recovered.

[0017] Refer to Figure 1 and Figure 2A water level gauge 5 is provided outside the recovery tank 12, and both ends of the water level gauge 5 are fixedly passed through the outer wall of the recovery tank 12. The water level gauge 5 is in a connected state with the recovery tank 12. The amount of the neutralized liquid recovered in the recovery tank 12 can be seen through the water level gauge 5.

[0018] Reference Figure 1 and Figure 2 A drain pipe 6 having an automatic manual valve is fixedly passed through the bottom end of the outer wall of the recovery tank 12, and the drain pipe 6 is in a connected state with the recovery tank 12. By opening the valve of the drain pipe 6, the neutralized liquid recovered in the recovery tank 12 can be discharged.

[0019] The implementation principle of the acid mist purification and recovery device of the embodiment of the present application is as follows: when in use, after one end of the mist exhaust pipe 3 is connected to the mist exhaust port of the external chemical processing equipment, the mist exhaust pipe 3 can discharge the acid mist into the interior of the processing tank 13. At this time, when the acid mist passes through the filter holes of the water bath net 1 41 and the water bath net 2 42, the water bath net 1 41 and the water bath net 2 42 cooperate to disperse the acid mist and filter the impurities in the acid mist. At the same time, the two groups of atomizing nozzles 43 spray the alkaline solution into the water bath net 1 41 and the water bath net 2 42. When the acid mist passes through the filter holes of water bath net 1 41 and water bath net 2 42, a water film will be formed. When the acid mist passes through the filter holes of water bath net 1 41 and water bath net 2 42, the acid mist will fully contact with the alkaline liquid water film, so that it can be fully neutralized. The neutralized liquid finally flows to the inside of the recovery tank 12 through the connecting pipe 17 to be recovered. The amount of neutralized liquid recovered in the recovery tank 12 can be seen through the water level meter 5, so that the valve of the drain pipe 6 can be opened in time to discharge the neutralized liquid recovered in the recovery tank 12.
