[0042] Embodiment 2

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

[0044] The present invention adopts a designed pre-treatment conveying mechanism, and the dust gas that is about to enter the dust removal tower 100 is sprayed with an atomizing nozzle 302 in the dust entry pipe 101 through one side of the dust removal tower 100 to reduce dust, thereby removing large particles of dust in the dust gas. After the dust gas enters the dust removal tower 100, it passes through the airflow guide uniform distribution pipe 300 for uniform distribution, and the dust and dirt on the inner walls of multiple groups of holes and grooves 309 in the airflow guide uniform distribution pipe 300 are cleaned to avoid dust and dirt accumulation on the inner walls of the holes and grooves 309 after long-term use, thereby reducing the size of the inner walls of the holes and grooves 309, thereby affecting the speed of dust and gas passing through the holes and grooves 309, thereby improving the subsequent purification effect.

[0045] Embodiment 3

[0046] Based on Example 2, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The dust removal tower 100 is also provided with a purification component for purifying the dust entering the dust removal tower 100. The purification component includes:

[0047] Two groups of multi-layer multi-fold inclined plate dehydrators 200, a clean water inlet pipe 201 and a circulating water inlet pipe 206. The clean water inlet pipe 201 is fixedly provided with multiple groups of upper spray heads 202. The upper spray heads 202 spray water upward to rinse the bottom of the multi-layer multi-fold inclined plate dehydrators 200, and are used to wash and clean the surface of the multi-layer multi-fold inclined plate dehydrators 200. The circulating water inlet pipe 206 is fixedly provided with multiple groups of lower spray heads 203 to attach and reduce dust;

[0048] Two groups of multi-layer evenly distributed porous bubbling plates 204 are fixedly arranged inside the dust removal tower 100, and the multi-layer evenly distributed porous bubbling plates 204 are used to generate water bubbles.

[0049] The present invention designs a purification component, and when dust and dust gas pass through the purification component for purification, bubbles will be generated after passing through the multiple layers of uniformly distributed porous bubbling plates 204. The dust adheres to the bubbles to reduce the dust, and the water mist sprayed by the lower spray head 203 and the upper spray head 202 is used to reduce the dust. The remaining gas after the dust is reduced by contacting the dust with the bubbles and the water mist sprayed by the lower spray head 203 and the upper spray head 202 forms clean gas, and then the clean gas containing water is dehydrated through the multiple layers of multi-fold inclined plate dehydrator 200, so the dust removal efficiency is improved, and the emission concentration of dust particles meets the ultra-low emission requirements, thereby realizing low energy consumption, high dust removal efficiency, low water consumption, low failure rate, and stable and reliable operation of high-efficiency wet dust removal.

[0050] In this embodiment, a reducer 310 is provided between the dust gas inlet pipe 101 and the dust removal tower 100, a cone bucket 102 is fixedly provided at the bottom of the dust removal tower 100, and dust and water are discharged outward through the bottom of the cone bucket 102 during the dust removal process. 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] During use, external dust-laden gas enters through the dust-laden gas inlet pipe 101, and at this time, water mist is sprayed to the incoming dust-laden gas through the atomizing nozzle 302 to pre-dust the large particles of dust in the dust-laden gas. Then, the dust-laden gas enters the dust removal tower 100, and enters the airflow guide uniform distribution pipe 300. Under the action of the bottom inclined surface, the airflow evenly enters different hole grooves 309, and then enters the bottom of the multi-layer uniformly distributed porous bubbling plate 204, and passes through the multi-layer uniformly distributed porous bubbling plate 204. The spray head 203 at the top of the bubble plate 204 sprays atomized water droplets which condense and settle with the dust in the dust gas. The settled droplets form a layer of water film on the multi-layer evenly distributed porous bubble plate 204 below. The dust gas at the bottom of the multi-layer evenly distributed porous bubble plate 204 generates a large number of bubbles at the top after passing through the multi-layer evenly distributed porous bubble plate 204. The fine dust in the dust fully contacts and adheres to the bubbles and is captured. The dust is captured by the multi-layer evenly distributed porous bubble plate 204 and the atomized dust collector.

[0052] Then the clean gas enters the multi-layer multi-fold inclined plate dehydrator 200, which is a labyrinth-type arrangement. After passing through the multi-layer multi-fold inclined plate dehydrator 200, the clean gas containing fine droplets collides with fine mist droplets and adheres to the surface thereof, and then forms larger water droplets and drops 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 being dehydrated by the multi-layer multi-fold inclined plate dehydrator 200, the clean gas is discharged to the outside through the gas transmission pipeline 103 and the chimney 105, thereby realizing a combination of dust removal methods and increasing the dust removal effect.

[0053] When dust and dirt adhere to the inner wall of the hole groove 309 during use of the air flow guide uniform distribution tube 300, the reduction motor 306 is turned on, and then the nut seat 320 is driven to tilt to the right, thereby driving the inclined panel at the top of the nut seat 320 to move. At this time, the bottom of the inclined rod 315 at the bottom of the long brush 305 located at different heights in different hole grooves 309 touches the inclined panel and moves upward, thereby driving the long brush 305 to move upward. Then, when the nut seat 320 leaves under the inclined rod 315, the long brush 305 moves in the opposite direction again. When the nut seat 320 moves to the right to the extreme position, the reduction motor 306 is reversed, driving the nut seat 320 to move to the left, and driving the long brush 305 to move again. This is repeated many times, and the dirt on the inner wall of the hole groove 309 is cleaned by the long brush 305.

[0054] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
