However, uneven airflow distribution can easily occur during the process of entering the purification filling layer, affecting the dust removal effect. There are also problems such as easy clogging of the internal dust filtration filling layer, incomplete dehydration of the water mist after internal spraying, excessive concentration of particulate matter at the top outlet of the chimney, and mist droplet phenomenon in the chimney. To address these issues, we propose a high-efficiency wet scrubber device. Utility Model Content

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) This utility model uses a pre-treatment conveying mechanism to spray the dust and gas about to enter the dust removal tower through an atomizing nozzle in the dust gas entry pipe on one side of the dust removal tower to remove large dust particles. After entering the dust removal tower, the dust and gas pass through the airflow guide plate to distribute the airflow evenly, so that the dust and gas enter the top of the dust removal tower for purification. During the purification process, the dust and gas are evenly introduced into the purification device for purification, which increases the purification effect of dust. Moreover, the cleaning component can clean the dirt on the inner wall of the multiple sets of holes and grooves in the airflow guide plate, which prevents the dirt from accumulating on the inner wall of the holes and grooves after long-term use, thus reducing the size of the inner wall of the holes and grooves and affecting the speed of the dust and gas passing through the holes and grooves, thereby improving the subsequent purification effect.

[0023] (2) Through the design of the purification component, the dust and gas will bubble after passing through multiple layers of evenly distributed porous bubble plates when the dust and gas pass through the purification component. The dust adheres to the water bubbles, which can reduce the dust. The water mist sprayed from the lower spray head and the upper spray head will treat the dust. After the dust is treated by contacting the water bubbles, the lower spray head and the upper spray head, the remaining gas forms clean gas. Then, the clean gas containing water is dehydrated in the multi-layer multi-fold inclined plate dehydrator. The dust removal efficiency is improved, and the dust particulate matter emission concentration meets the ultra-low emission requirements. It realizes a high-efficiency wet dust removal with low energy consumption, high dust removal efficiency, low water consumption, low failure rate and stable and reliable operation.

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

[0035] Example 1

[0036] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 This utility model provides a technical solution: a high-efficiency wet dust removal device, including a dust removal tower 100, a dust gas inlet pipe 101 and a gas conveying pipe 103. The dust removal tower 100 is provided with a pretreatment conveying mechanism, which includes an airflow guiding and distributing pipe 300, which is provided inside the dust removal tower 100. The airflow guiding and distributing pipe 300 has multiple sets of holes and slots 309 inside, so that the dust gas entering the dust removal tower 100 can pass evenly through the holes and slots 309 in the airflow guiding and distributing pipe 300. A cleaning component is provided on the airflow guiding and distributing pipe 300.

[0037] The cleaning component includes a lead screw body 307 and a long strip brush 305 disposed inside the slot 309. Multiple long strip brushes 305 gradually increase in height and length from left to right according to the shape of the airflow guide pipe 300. An upper rod 312 is fixedly disposed on the top of the long strip brush 305, and a diagonal rod 315 is fixedly disposed on the bottom of the long strip brush 305.

[0038] The dust collector tower 100 has an inclined plate 311 inside, and an inclined rod 315 can move up and down inside the inclined plate 311. A connecting plate is fixed between the bottom of the inclined plate 311 and the inner wall of the dust collector tower 100. The bottom of the inclined rod 315 passes through the inside of the inclined plate 311. A nut seat 320 is provided on the outside of the screw body 307. The nut seat 320 can move left and right on the screw body 307. An inclined plate is fixed on the top of the nut seat 320. The left end of the screw body 307 and the left end of the limiting rod 308 are fixed together by a connector.

[0039] A support bearing 317 is sleeved on the bottom of the lead screw body 307. An upper connecting frame 318 and a lower connecting frame 316 are fixedly installed between the support bearing 317 and the inner wall of the dust removal tower 100, respectively. A reduction motor 306 is fixedly installed at the bottom of the lead screw body 307, which can drive the lead screw body 307 to rotate.

[0040] A mechanical bearing 319 is embedded inside the dust collector tower 100. The mechanical bearing 319 can support the lead screw body 307. The bottom end of the lead screw body 307 passes through the interior of the mechanical bearing 319. A limiting rod 308 is fixedly installed on the lower connecting frame 316. A collar is fixedly installed on the outside of the nut seat 320. When the nut seat 320 moves on the lead screw body 307, it can drive the collar to slide on the limiting rod 308. The collar is located at the end of the limiting rod 308 and is used to limit the movement of the nut seat 320.

[0041] The dust collector tower 100 has an upper plate 304 fixedly installed inside. The top of the upper rod 312 passes through the interior of the upper plate 304. An upper circular plate 303 is fixedly installed on the top of the upper rod 312. A connecting spring 313 and a lower ring 314 are respectively sleeved on the outside of the upper rod 312. When the long brush 305 moves up and down, it will drive the top of the upper rod 312 to move up and down inside the upper plate 304. The connecting spring 313 can generate tension when the upper rod 312 moves upward. Then, when the long brush 305 descends, the connecting spring 313 resets, which can make the upper rod 312 and the long brush 305 quickly descend to their original positions. The lower ring 314 is fixed on the outside of the upper rod 312, and the connecting spring 313 is fixed between the lower ring 314 and the upper plate 304.

[0042] Example 2

[0043] Please refer to Example 1. Figure 1 ,Figure 3 and Figure 5 The pretreatment conveying mechanism also includes a water conveying pipe 301 and an atomizing nozzle 302. The water conveying pipe 301 is installed on the dust and gas inlet pipe 101 and is used to convey clean water to the atomizing nozzle 302. The atomizing nozzle 302 is fixed to the end of the water conveying pipe 301.

[0044] This invention utilizes a pre-treatment conveying mechanism to spray and reduce dust and gas entering the dust removal tower 100 through an atomizing nozzle 302 in the dust-gas inlet pipe 101 on one side of the dust removal tower 100. This removes large dust particles from the dust and gas. After entering the dust removal tower 100, the dust and gas pass through an airflow distribution pipe 300 to clean the dirt on the inner walls of the multiple sets of perforated grooves 309 in the airflow distribution pipe 300. This prevents dirt from accumulating on the inner walls of the perforated grooves 309 over time, which would reduce the size of the inner walls of the perforated grooves 309 and thus affect the speed at which the dust and gas pass through the perforated grooves 309, thereby improving the subsequent purification effect.

[0045] Example 3

[0046] Please refer to Example 2. Figure 1 , Figure 2 , Figure 3 and Figure 5 The dust removal tower 100 is also equipped with a purification component to purify the dust entering the dust removal tower 100. The purification component includes:

[0047] Two sets of multi-layer multi-fold inclined plate dewatering devices 200, a clean water inlet pipe 201 and a circulating water inlet pipe 206 are provided. Multiple sets of upper spray heads 202 are fixedly installed on the clean water inlet pipe 201. The upper spray heads 202 spray water upward to rinse the bottom of the multi-layer multi-fold inclined plate dewatering device 200 and clean the surface of the multi-layer multi-fold inclined plate dewatering device 200. Multiple sets of lower spray heads 203 are fixedly installed on the circulating water inlet pipe 206 and are used to attach and reduce dust.

[0048] The dust removal tower 100 is also equipped with two sets of multi-layered, evenly distributed porous bubble-generating plates 204, which are used to generate water bubbles.

[0049] This utility model utilizes a designed purification component. When dust and gas pass through the purification component, they are bubbled after passing through multiple layers of evenly distributed porous bubble plates 204. The dust adheres to the water bubbles, reducing dust levels. The water mist sprayed from the lower spray head 203 and the upper spray head 202 further reduces dust. After dust is reduced by contact with the water bubbles, the water mist sprayed from the lower spray head 203 and the upper spray head 202, the remaining gas forms clean gas. Then, the clean gas containing water passes through a multi-layer, multi-fold inclined plate dehydrator 200 for dehydration treatment. This improves dust removal efficiency, and the dust particulate matter emission concentration meets ultra-low emission requirements. It achieves high-efficiency wet dust removal with low energy consumption, high dust removal efficiency, low water consumption, low failure rate, and stable and reliable operation.

[0050] In this embodiment, a variable diameter port 310 is provided between the dust gas inlet pipe 101 and the dust removal tower 100. A cone hopper 102 is fixedly provided at the bottom of the dust removal tower 100. During the dust removal process, dust and water are discharged outward together through the bottom of the cone hopper 102. An induced draft fan 104 is fixedly provided at the end of the gas transmission pipe 103, and a chimney 105 is provided on the induced draft fan 104.

[0051] In operation, external dust-laden gas enters through the dust inlet pipe 101. Water mist is then sprayed onto the gas through the atomizing nozzle 302 to pre-settle large dust particles. The gas then enters the dust removal tower 100 and the airflow distribution pipe 300. Under the action of the inclined bottom surface, the airflow evenly enters different perforated slots 309, and then reaches the bottom of the multi-layered evenly distributed porous bubbler plate 204. The atomized water droplets sprayed from the top spray head 203 of the bubble plate 204 condense and settle with the dust in the dusty gas. The settled water droplets form a water film covering the multi-layered evenly distributed porous bubble plate 204 below. The dusty gas below the multi-layered evenly distributed porous bubble plate 204 generates a large number of water bubbles in the upper part after passing through the multi-layered evenly distributed porous bubble plate 204. The fine dust in the dust comes into full contact with the water bubbles, adheres and is captured. The dust is captured by the multi-layered evenly distributed porous bubble plate 204 and the atomized dust collection.

[0052] Then, the clean gas enters the multi-layer multi-fold inclined plate dehydrator 200. The multi-layer multi-fold inclined plate dehydrator 200 is designed in a labyrinth. After the clean gas containing fine droplets passes through the multi-layer multi-fold inclined plate dehydrator 200, it collides with the fine mist droplets and adheres to their surface, and then forms larger water droplets that drip down. At the same time, water is sprayed to the bottom of the multi-layer multi-fold inclined plate dehydrator 200 through the upper spray head 202 to wash away the dust at the bottom. After the clean gas is dehydrated by the multi-layer multi-fold inclined plate dehydrator 200, it is discharged to the outside through the gas transmission pipe 103 and the chimney 105, realizing a combination of multiple dust removal methods to increase the dust removal effect.

[0053] When dirt adheres to the inner wall of the slot 309 in the airflow distribution pipe 300 during use, the reduction motor 306 is turned on, which drives the nut seat 320 to tilt to the right, thereby moving the inclined plate at the top of the nut seat 320. At this time, the bottom of the inclined rod 315 of the long brush 305 at different heights in different slots 309 touches the inclined plate and moves upward, thereby driving the long brush 305 to move upward. Then, when the nut seat 320 leaves below the inclined rod 315, the long brush 305 moves in the opposite direction. When the nut seat 320 moves to the right to its limit position, the reduction motor 306 reverses, driving the nut seat 320 to move to the left, which again drives the long brush 305 to move. This process is repeated many times, and the dirt on the inner wall of the slot 309 is cleaned by the long brush 305.

[0054] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
