Description

Technical Field

[0001] This utility model relates to the field of resource and environmental technology, and in particular to an acid mist recovery device for an acid mist tower. Background Technology

[0002] A search revealed Chinese patent CN202023240893.7, which discloses an acid mist recovery device for an acid mist tower. The device includes an acid mist tower, a liquid purification tank, a discharge device, and a motor. The acid mist tower is installed on the ground. The liquid purification tank is located on one side of the acid mist tower via an inlet pipe and a fixing ring. The discharge device is located on the other side of the acid mist tower via the top of the tower and a mist delivery pipe. The motor is bolted to the bottom of the acid mist tower. This invention, by incorporating a liquid filtration device, can filter the treated liquid for reuse, significantly improving environmental protection and saving time previously required for post-use cleaning. The motor, L-shaped rotating rod, and soft brush allow for easy cleaning of the interior of the acid mist tower, preventing it from becoming dirty and cluttered over time.

[0003] However, during the implementation of the above technical solution, at least the following technical problems were discovered:

[0004] 1. Impurities generated during the reaction between acid mist and chemical solution, even after being cleaned by scrapers or other cleaning devices, remain in the acid mist solution. Therefore, it is necessary to collect and clean these impurities simultaneously to prevent excessive internal accumulation, which would consume the absorbent concentration, weaken the neutralization capacity of the acid mist, and ultimately reduce the acid mist removal efficiency.

[0005] 2. Acid mist is directly injected into the interior of the acid mist tower from the top. In the initial stage, the acid mist can only make preliminary contact with the surface of the liquid. In order to achieve a full mixing reaction between the acid mist and the liquid, a long reaction time is required. This mechanism makes it difficult to improve the acid mist recovery efficiency in actual operation, which becomes a key factor restricting the performance of the equipment. Utility Model Content

[0006] The purpose of this invention is to provide an acid mist recovery device for acid mist towers, which can simultaneously collect and clean surface impurities after the scraper and other devices have cleaned them, thus avoiding the accumulation of impurities that consumes the absorbent concentration, weakens the acid mist neutralization capacity, and addresses the problem that acid mist can only make initial contact with the surface of the liquid, while a long reaction time is required to achieve a full mixing reaction between the acid mist and the liquid.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an acid mist recovery device for an acid mist tower, comprising a tower body, wherein a storage tank is fixedly connected to the lower surface of the tower body for collecting the filtered acid solution, and further comprising:

[0008] Drive components: located inside the tower body;

[0009] Filter components: located inside the tower body;

[0010] Spray assembly: Located inside the tower body, with a discharge assembly located below the spray assembly.

[0011] In a preferred embodiment, the discharge component includes:

[0012] The mist inlet pipe is fixedly connected to the surface of the tower body;

[0013] Multiple support blocks are evenly and fixedly connected to the inner surface of the tower body;

[0014] The mist outlet pipe is fixedly connected to the inner surface of multiple support blocks and is connected to the mist inlet pipe;

[0015] Multiple mist outlets are evenly distributed on the lower surface of the mist outlet pipe.

[0016] In a preferred embodiment, the driving component includes:

[0017] The motor is located on the upper surface of the tower body;

[0018] The rotating shaft is located at the motor output end;

[0019] The turntable is fixedly connected to the bottom end of the rotating shaft;

[0020] Screw blades are fixedly connected to the surface of the rotating shaft.

[0021] In a preferred embodiment, the filtering component includes:

[0022] Filter plate one is fixedly connected to the inner surface of the tower body;

[0023] Filter plate two is fixedly connected to the inner surface of the tower body;

[0024] Scraper 1 is slidably connected to the outer surface of filter plate 1 and fixedly connected to the rotating shaft. A brush is provided on the lower surface of scraper 1.

[0025] Scraper 2 is slidably connected to the outer surface of filter plate 2 and fixedly connected to the turntable;

[0026] The collection frame is slidably connected to the lower surface of the filter plate.

[0027] In a preferred embodiment, the spray assembly includes:

[0028] The circulating pump is located outside the tower body;

[0029] The connecting pipe is fixedly connected at one end to the surface of the tower body and at the other end to the inlet of the circulating pump;

[0030] The output pipe is located at the output end of the circulating pump.

[0031] The annular pipe is fixedly connected to the inner surface of the tower body and connected to the output pipe;

[0032] Multiple nozzles are located on the outer surface of the annular tube.

[0033] In a preferred embodiment, a liquid outlet pipe is fixedly connected to the outer surface of the liquid storage tank, and a switch is provided on the outer surface of the liquid outlet pipe.

[0034] In a preferred embodiment, an inner tube is fixedly connected to one surface of the filter plate, and the inner surface of the inner tube is slidably connected to the auger blades.

[0035] In a preferred embodiment, the turntable is slidably connected to the filter plate.

[0036] Compared with the prior art, the advantages and positive effects of this utility model are as follows: When this utility model is used, the motor is started, and the scraper two slides on the upper surface of the filter plate two through the rotating shaft, so that the impurities generated on the surface after filtration fall onto the turntable. At the same time, the mist acid solution can also be stirred, further improving the fusion efficiency of acid mist and medicine solution. The rotating shaft drives the auger blades to rotate in the inner tube, and the bottom of the auger blades slides on the upper surface of the turntable, thereby driving the solution containing too many impurities at the bottom to move upward in the inner tube and be discharged through the outlet to fall onto the surface of the filter plate one for filtration. The rotating shaft drives the scraper one to slide on the upper surface of the filter plate one, scraping away the impurities generated on the surface of the filter plate one after filtration, preventing the filter screen from clogging, and at the same time, the impurities can fall into the collection box for unified collection and cleaning.

[0037] The solution required for removing acid mist is injected into the tower body through the outlet pipe. The circulation pump is started to spray the solution into the tower body through multiple nozzles on the outer surface of the annular pipe. The acid mist discharge pipe is connected to the mist inlet pipe, and acid mist is injected into the tower body through the mist outlet. Since the spraying components are located above the discharge components, the solution sprayed above can react more fully with the acidic waste gas rising below, thereby improving the absorption efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Example 1

[0046] Please see Figures 1 to 4 This utility model provides a technical solution: an acid mist recovery device for an acid mist tower, including a tower body 1, a storage tank 2, a drive assembly, a filter assembly, a spray assembly, and a discharge assembly, wherein the storage tank 2 is fixedly connected to the lower surface of the tower body 1 for collecting the mist acid solution.

[0047] The drive and filter components include: a motor 4, mounted on the upper surface of the tower body 1, for driving the equipment; a rotating shaft 401 fixedly connected to the output end of the motor 4; a turntable 402 fixedly connected to the lower surface of the rotating shaft 401; a scraper 603 fixedly connected to the outer surface of the turntable 402; the rotating shaft 401 drives the scraper 603 to slide on the surface of the filter plate 601, continuously scraping away impurities adhering to the surface of the filter plate 601, causing the impurities to fall onto the upper surface of the turntable 402; simultaneously, it can also agitate the mist acid solution, further improving the fusion efficiency of the acid mist and the liquid medicine; an auger blade 403 fixedly connected to the outer surface of the rotating shaft 401, the auger blade 403 slidingly connected to the inner surface of the inner tube 7; and a filter plate 6 fixedly connected to the outer surface of the inner tube 7. The rotating shaft 401 is rotated by starting the motor 4. The rotating shaft 401 drives the auger blades 403 to rotate. The bottom of the auger blades 403 slides on the upper surface of the turntable 402, causing the impurities at the bottom to move upwards and fall onto the filter plate 6 through the outlet. A scraper 602 is fixedly connected to the outer surface of the rotating shaft 401 and is slidably connected to the filter plate 6. The lower surface of the filter plate 6 is fixedly connected to the lower surface of the collection frame 604. The rotating shaft 401 drives the scraper 602 to slide on the surface of the filter plate 6. The bottom brush continuously scrapes away the impurities attached to the surface of the filter plate 6, allowing the filtered impurities to fall into the collection frame 604 for unified collection and cleaning. This prevents excessive impurities from clogging the filter plate 6 and also filters the mist acid solution again, further reducing the impurities in the mist acid solution and reducing pollution to the mist acid solution.

[0048] In the specific implementation process: The motor 4 is started, driving the turntable 401 to rotate via the shaft 401. Simultaneously, the scraper 603 slides on the upper surface of the filter plate 601, continuously scraping away impurities adhering to the surface of the filter plate 601. The impurities generated on the filtered surface fall onto the turntable 401. Simultaneously, the acid mist solution is agitated, further improving the fusion efficiency of the acid mist and the liquid. The shaft 401 drives the auger blades 403 to rotate within the inner tube 7. The bottom of the auger blades 403 slides on the upper surface of the turntable 402, causing the solution with excessive impurities at the bottom to move upwards within the inner tube 7 and be discharged through the outlet onto the surface of the filter plate 6 for filtration. The shaft 401 drives the scraper 602 to slide on the upper surface of the filter plate 6, continuously scraping away impurities adhering to the surface of the filter plate 6 through the bottom brush, preventing filter clogging. Simultaneously, debris falls into the collection frame 604 for unified collection and cleaning.

[0049] Example 2

[0050] It should be noted that, based on Example 1, the spray assembly and the discharge assembly include:

[0051] The mist inlet pipe 3 is fixed to the surface of the tower body 1 and its outlet is connected to the mist outlet pipe 302. It is fixed to the inner surface of multiple support blocks 301 to ensure stability. Multiple mist outlets 303 are evenly arranged on the lower surface of the mist outlet pipe 302. A liquid storage tank 2 is fixedly connected to the lower surface of the tower body 1. The liquid storage tank 2 is connected to the circulation pump 5 through the connecting pipe 501. The output end of the circulation pump 5 is provided with an output pipe 502. The annular pipe 503 is fixedly connected to the inner surface of the tower body 1 and connected to the output pipe 502. Multiple nozzles 504 are arranged on the outer surface of the annular pipe 503. The solution is sprayed into the tower body 1 through the multiple nozzles 504. Since the spraying assembly is located above the discharge assembly, the solution sprayed above can react more fully with the rising acidic waste gas below, thereby improving the absorption efficiency.

[0052] In the specific implementation process: First, the solution required for removing acid mist is injected into the tower body 1 through the liquid outlet pipe 201. Then, the circulation pump 5 is started to spray the solution into the tower body 1 through multiple nozzles 504 on the outer surface of the annular pipe 503. The acid mist discharge pipe is connected to the mist inlet pipe 3, and the solution is injected into the tower body 1 through the mist outlet 303. Since the spraying component is located above the discharge component, the solution sprayed above can react more fully with the acidic waste gas rising below, thereby improving the absorption efficiency.

[0053] Working principle:

[0054] The motor 4 is started, which drives the turntable 401 to rotate via the shaft 401. Simultaneously, the scraper 603 slides on the upper surface of the filter plate 601, continuously scraping away impurities adhering to the surface of the filter plate 601. The impurities generated on the surface after filtration fall onto the turntable 401. At the same time, the mist acid solution is also stirred, further improving the fusion efficiency of the acid mist and the liquid. The shaft 401 drives the auger blade 403 to rotate in the inner tube 7. The bottom end of the auger blade 403 slides on the upper surface of the turntable 402, thereby driving the solution containing too many impurities at the bottom to move upward in the inner tube 7. It is discharged through the outlet and falls onto the surface of the filter plate 6 for filtration. The shaft 401 drives the scraper 602 to slide on the upper surface of the filter plate 6. The bottom brush continuously scrapes away impurities adhering to the surface of the filter plate 6, preventing the filter screen from clogging. At the same time, the debris falls into the collection frame 604 for unified collection and cleaning.

[0055] The solution required for removing acid mist is injected into the tower body 1 through the outlet pipe 201. The circulation pump 5 is started and sprays the solution into the tower body 1 through multiple nozzles 504 on the outer surface of the annular pipe 503. The acid mist discharge pipe is connected to the mist inlet pipe 3 and injected into the interior through the mist outlet 303. Since the spraying component is located above the discharge component, the solution sprayed above can react more fully with the acidic waste gas rising below, thereby improving the absorption efficiency.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
