[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1 , which is an industrial smoke removal device for air pollution prevention and control disclosed in an embodiment of the utility model, comprises a tower body 1, a smoke outlet 11 is arranged on the top of the tower body 1, a smoke inlet 12 is arranged on the bottom, a through pipe 2 is fixedly installed along the axial direction of the tower body 1, the through pipe 2 is coaxially arranged with the tower body 1, a spiral channel plate 3 is fixedly installed in the tower body 1, the spiral channel plate 3 forms a spiral airway between the tower body 1 and the through pipe 2, and the inlet and outlet of the spiral airway correspond to the smoke inlet 12 and the smoke outlet 1 respectively 1, an atomizing nozzle 41 is fixedly installed on the outer side of the core tube 2, and each layer of the spiral airway has a plurality of atomizing nozzles 41 in a circumferential array. An atomizing pipe 42 is installed in the core tube 2, and the plurality of atomizing pipes 42 are respectively connected to the atomizing nozzles 41. The atomizing pipe 42 is connected to a solution pool 44, and an atomizing pump 43 is arranged in the solution pool 44. The output end of the atomizing pump 43 is connected to the atomizing pipe 42. A drainage hole is provided at the bottom of the spiral channel plate 3, and a drainage port is provided at the bottom of the tower body 1. Please refer to Figure 2 A waste liquid pool 5 is arranged below the tower body 1 , and a gas stop pipe 51 is connected to the liquid discharge port. The gas stop pipe 51 is a water trap structure. The gas stop pipe 51 is far away from one end of the liquid discharge port and is connected to the waste liquid pool 5 .

[0034] Specifically, a spiral channel plate 3 is fixedly installed in the tower body 1 to transform the airflow channel into a spiral channel, extending the airflow ascending path, and an atomizing nozzle 41 is arranged in the through pipe 2. The atomizing nozzle 41 is installed in a circular array and cooperates with the spiral ascending channel so that the atomizing nozzle 41 corresponds to different heights of the layer of airflow to increase the contact of the airflow.

[0035] In this way, by providing the spiral channel to extend the airflow path and the layered corresponding atomizing nozzle 41, the contact between the atomized solution and the airflow is increased, thereby improving the cleaning effect of the atomized solution on the airflow.

[0036] In some feasible embodiments, the tower body 1 is cylindrical, and the through pipe 2 is a passage for the pipeline of the atomizing nozzle 41. By setting the through pipe 2, each atomizing nozzle 41 can be connected to the atomizing pipeline 42 through an independent pipeline, thereby reducing pressure loss and making the atomizing effect of the atomizing nozzle 41 as consistent as possible to achieve a better atomization effect. A drainage hole is provided at the lower end of the spiral plate 3. The water sprayed by the atomizing nozzle 41 flows along the spiral plate 3 to the drainage hole and then enters the drainage port. A water trap-shaped air stop pipe 51 is provided at the drainage port to store water in the air stop pipe 51 to prevent air flow from entering the waste liquid pool 5.

[0037] As a specific implementation of the industrial air pollution control smoke removal equipment provided by the utility model, please refer to Figure 2 A filter plate 52 is installed in the waste liquid pool 5 , and a reflux pump 53 is installed on the side of the filter plate 52 away from the air stop pipe 51 , and the reflux pump 53 is connected to the atomization pipeline 42 .

[0038] In general, during the spraying process of the atomized solution, part of the solution does not react with the harmful substances in the flue gas, or part of the solution can be recycled. By setting the filter plate 52, the washed solid particles such as dust are filtered to prevent the particles from clogging the atomizing nozzle 41.

[0039] Furthermore, a control valve is installed on the pipe connected to the atomization pipe 42 .

[0040] It should be understood that the reflux liquid in the waste liquid pool 5 is refluxed after filtering solid impurities. If the solution contains a solvent that reacts with the main pollutants, the solvent content in the reflux liquid is reduced, which may affect the control effect of the gas. By setting a control valve, the flow rate of the reflux liquid is controlled to achieve an appropriate usage amount.

[0041] For further information, see Figure 1 A plate washing port 31 is installed at the uppermost end of the spiral plate 3 , and the plate washing port 31 is connected to the reflux pump 53 .

[0042] It should be understood that the flue gas may contain particulate matter such as smoke and dust, which adhere to the surface of the spiral plate 3 when the atomized solution flows into the waste liquid pool 5 along the spiral plate 3. By setting the plate washing port 31, the liquid in the waste liquid pool 5 can be continuously circulated along the spiral plate 3 to clean the surface of the spiral plate 3, thereby reducing the maintenance work on the spiral plate 3.

[0043] In some feasible embodiments, the plate washing port 31 is in the shape of a rectangular pipe, and the plate washing port 31 is connected to the reflux pump 53 through a pipe.

[0044] For further information, see Figure 2 A partition plate 54 is installed in the waste liquid pool 5, and the partition plate 54 makes the space in the waste liquid pool 5 U-shaped. The filter plate 52 is installed perpendicular to the partition plate 54 at the bottom of one side of the partition plate 54, and the reflux pump 53 is installed above the filter plate 52.

[0045] It should be understood that the filter plate 52 is used to filter solid particles in the waste liquid. A U-shaped communicating vessel is set by the partition plate 54, and the filter plate 52 is installed on one side of the communicating vessel to form a height difference between the waste liquid and the filtered liquid. The filtering effect is increased by water pressure. At the same time, the filter plate 52 contacts the waste liquid to prevent it from facing downward, and the particles can also fall to the bottom of the waste liquid pool 5 to reduce clogging.

[0046] As another specific implementation of the industrial air pollution control smoke removal equipment provided by the utility model, please refer to Figure 1 The smoke inlet 12 is connected to a primary filter box 13, a dust filter plate 131 is arranged in the middle of the primary filter box 13, the smoke inlet 12 is connected to the top of the primary filter box 13, and an air inlet is opened below the primary filter box 13.

[0047] In combination with specific usage scenarios, some flue gases contain a large amount of dust. The dust is initially filtered through the primary filter box 13 to reduce the washing of the dust by the atomized solution, so that the atomized solution reacts more with the pollutants to achieve a better cleaning effect.

[0048] Furthermore, a vibration motor is provided on the outside of the primary filter box 13 at the position of the dust filter plate 131 .

[0049] It should be understood that by providing a vibration motor, the dust filter plate 131 is vibrated to reduce the possibility of dust clogging the filter holes.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
