AI Technical Summary
When treating exhaust gas, existing spray towers require shutdown for cleaning of contaminants, which affects work efficiency. Furthermore, the water mist is not tight or too thin, resulting in incomplete filtration of exhaust gas and reduced filtration efficiency.
Multiple horn-shaped spray devices and conical mesh structures were designed, combined with wastewater recovery devices and scrapers, to achieve non-stop cleaning of the filter screen, and to improve filtration efficiency through the cross-flow of water mist and exhaust gas.
This allows for continuous cleaning of the filter screen, improving the filtration efficiency of the spray tower, ensuring complete treatment of exhaust gas, and preventing pollutant emissions.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dust treatment facilities, and in particular to a high-efficiency spray tower. Background Technology
[0002] In some industrial production processes, a large amount of waste gas is emitted. In order to ensure that the waste gas meets the emission standards, spray towers are generally used to treat the waste gas.
[0003] In the treatment process of a spray tower, exhaust gas is first discharged into the tower, followed by the introduction of water mist. The water mist encapsulates the dust particles, which are then filtered through a filter screen. The filtered water is discharged and reused, while the dust particles remain on the filter screen. Over time, dirt accumulates on the filter screen, requiring timely cleaning. However, in current technology, cleaning requires shutting down the machine, which inevitably affects work efficiency. Furthermore, during the water mist formation process, if the water mist is not properly sealed or is too thin, some exhaust gas will pass through the mist and be discharged from the exhaust port, preventing some exhaust gas from being filtered and settling, causing pollution and affecting the filtration efficiency of the spray tower. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model provides a spray tower that can filter efficiently and be cleaned without shutting down.
[0005] This utility model is achieved through the following technical solution:
[0006] A high-efficiency spray tower includes a tower body, which has an air inlet, a water outlet pipe, and several spray devices. Each spray device has several sprayed water mists forming intersecting funnel-shaped covers. A mesh plate is installed inside the tower body, located between the spray devices and the air inlet. The mesh plate has several conical meshes, one below each funnel-shaped cover. There are several water outlet pipes, each equipped with a switch and a wastewater recovery device. Each wastewater recovery device is equipped with a circulating water pipe connected to the spray devices.
[0007] The wastewater recycling device includes a tank, a filter screen is installed inside the tank, a circulating water pipe is located above the filter screen, and an outlet pipe is located below the filter screen; the tank is also equipped with a drain pipe.
[0008] The bottom of the tank is equipped with a motor, and the output end of the motor extends upward into the inside of the tank and is connected to a scraper.
[0009] The scraper has two parts, each scraper including a scraper blade and a serrated blade arranged side by side.
[0010] The filter screen is a filter screen.
[0011] The bottom of the tank is inclined, and the sewage pipe is installed along the slope of the bottom of the tank.
[0012] A circulation pump is installed on the circulating water pipe.
[0013] The sum of the water flow rates of all the aforementioned horn covers shall not exceed the sum of the flow rates of all the water outlet pipes.
[0014] The beneficial effects of this utility model are:
[0015] This invention features multiple conical meshes, with each horn-shaped cover corresponding to one conical mesh. The exhaust gas coming from the conical meshes inevitably passes through the water mist coming down from the horn-shaped covers, thus treating the exhaust gas. After the water mist is sprayed out, some water will inevitably remain temporarily on the mesh plate, so the exhaust gas coming up from the mesh plate will also be treated by this part of the water. This way, there will be no situation where the exhaust gas is not treated, thus improving the filtration efficiency of the spray tower.
[0016] This invention also includes multiple wastewater recovery devices. When the filter screen needs to be cleaned, only some of the wastewater recovery devices need to be stopped, so the operation of the spray tower is not affected and the sewage discharge process is completed without stopping the spray tower.

Detailed Implementation
[0025] The attached figure shows a specific embodiment of this utility model.
[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0028] like Figures 1 to 6 As shown, this high-efficiency spray tower includes a tower body 1, an air inlet 2 installed on the tower body 1, a spray device 4 installed inside the tower body 1, and a mesh plate 5 installed below the spray device 4, with the mesh plate 5 located above the air inlet 2; the spray device 4 includes several horn covers 401, and the water mist sprayed from the horn covers 401 forms an intersection, and each horn cover 401 has a raised conical mesh 6 on the mesh plate 5 below it, the tip of the conical mesh 6 being able to approach the horn cover 401.
[0029] A pipe is installed at the lower end of the tower body 1, and the pipe is further split into several outlet pipes 3. A switch 301 is installed on each outlet pipe 3. Each outlet pipe 3 is connected to a wastewater recycling device. Each wastewater recycling device is equipped with a sewage pipe 13. The wastewater recycling device includes a tank body 8. The lower end of the tank body 8 is preferably an inclined bottom. The sewage pipe 13 is set along the slope of the bottom of the tank body 8.
[0030] A circulating water pipe 7 is installed on the tank body 8, and a circulating pump 701 is installed on the circulating water pipe 7. The circulating pump 701 is connected upward to the spray device 4.
[0031] Install a filter screen 9 inside the tank 8. The filter screen 9 is preferably a relatively hard filter plate. The filter screen 9 is located between the circulating water pipe 7 and the outlet water pipe 3.
[0032] A motor 10 is installed at the bottom of the tank 8, with its output end extending upwards into the tank 8 and connected to a scraper. The scraper is in close contact with the lower surface of the filter screen 9. There are two scrapers, each with a grooved cross-section, except that one side is a scraper blade 11 and the other side is a serrated blade 12, or comb-like blade. The two scrapers have the same structure but face opposite directions. Figures 4 to 6 As shown, when the scraper rotates, the scraper 11 and the toothed plate 12 are arranged at intervals.
[0033] Ideally, the two scrapers should fit together seamlessly, or even be combined into one.
[0034] The usage process is as follows:
[0035] After the machine is turned on, water mist is sprayed out from the horn cover 401, covering the conical mesh 6. Some of the water passes through the conical mesh 6 and flows down, while some flows down through the mesh plate 5. These water channels are the necessary paths for the exhaust gas to rise. The water and exhaust gas converge, encapsulating and carrying away the particles in the exhaust gas. The presence of the conical mesh 6 also increases the convergence area and improves the filtration efficiency.
[0036] To clean the wastewater recycling device, simply turn off the switch 301 on the outlet pipe 3 connected to the wastewater recycling device, start the motor 10, and the scraper will rotate. The serrated plate 12 will scrape up the filaments adhering to the filter screen 9, as well as scrape up or cut other dirt. Then, the scraper 11 behind it will scrape off the remaining dirt and discharge it through the drain pipe.
