[0028] 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. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0029] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0030] Reference Figure 1-6 A wet water bath dust removal system according to the present embodiment is described.

[0031] The treatment system includes a shell 1, and the bottom and top of the shell 1 are respectively provided with an air inlet port and an air outlet port. The bottom end of the shell 1 is a conical funnel portion, and the liquid dripping downwards in the shell 1 gathers at the funnel portion. The flue gas entering from the air inlet port contacts the gathered liquid and the continuously dripping liquid, and performs the first contact to preliminarily reduce the dust in the gas. The first treatment mechanism and the second treatment mechanism are sequentially arranged on the shell 1 along the airflow direction from the air inlet port to the air outlet port;

[0032] In the top view projection, the shell 1 is circular or rectangular; when the shell 1 is circular, the first processing mechanism is also circular in the top view projection, matching the shell 1; when the shell 1 is rectangular, the first processing mechanism is also rectangular in the top view projection, such as a rectangle, matching the shell 1.

[0033] The first processing mechanism is arranged in the housing 1, and includes a mesh assembly 4, the mesh assembly 4 includes a frame and a filter membrane 41 arranged on the frame, and a clamping cavity 42 for gas to move upward is formed between two adjacent filter membranes 41;

[0034] When the flue gas moves upward, it drifts upward along the cavity 42 between the two filter membranes 41, and the water drips downward from the cavity 42 and contacts the flue gas, making a second contact, further reducing the dust in the gas. At the same time, the flue gas contacts the filter membrane 41, causing the dust in the flue gas to adhere to the filter membrane 41. As the water drips, the filter membrane 41 is flushed, achieving the effect of wetting and dust removal of the filter membrane 41, so that the filter membrane 41 can continuously adhere to the dust. In this embodiment, the filter membrane 41 is a corrosion-resistant mesh.

[0035] In one embodiment, the frame includes a plurality of strip cylinders 43 arranged in parallel, and a clamping groove 48 capable of fixing the filter membrane 41 is formed in the strip cylinder 43. A filter screen 44 is connected between two adjacent strip cylinders 43, and a water collecting tank 45 is formed above the filter screen 44 and enclosed by the strip cylinders 43 on both sides;

[0036] The clamping cavity 42 is located at the bottom of the filter screen 44 ; the filter screen membrane 41 is arranged on the strip-shaped cylinder 43 .

[0037] With the above-mentioned implementation, the water is collected in the water collecting tank 45 and drips downward from the filter screen 44 into the clamping cavity 42 to achieve contact with the flue gas, thus achieving a second level of contact and further reducing the dust in the gas.

[0038] Furthermore, an open groove 46 is opened on one side of the strip cylinder 43, and a gap hole 49 is opened at the bottom of the strip cylinder 43 close to the filter membrane 41; wherein, a liquid flow channel 47 is formed in the strip cylinder 43 and extends from the open groove 46 to the gap hole 49, so that the water in the water collection tank 45 can fall onto the filter membrane 41 through the gap hole 49.

[0039] In one embodiment, the water dripping onto the filter membrane 41 is formed by the deviation of the filter 44 when dripping downward. In another embodiment, a liquid flow channel 47 is formed in the strip cylinder 43, so that the water in the water collection tank 45 enters the liquid flow channel 47 through the opening groove 46, flows out through the gap hole 49 and flushes on the top of the filter membrane 41, so as to achieve the effect of wetting the filter membrane 41 and flushing the dust, so that the filter membrane 41 can continuously adhere to the dust.

[0040] The frame also includes a bottom frame, the bottom of the filter membrane 41 is fixed on the bottom frame, and a strip hole is opened on the bottom frame to communicate with the clamping cavity 42. In order to stabilize the installation of the filter membrane 41, the bottom of the filter membrane 41 is fixed on the bottom frame, and the bottom frame is fixed on the housing 1. The filter membrane 41 can be vertically arranged in the housing 1, ensuring that the filter membrane 41 is bent and fitted to close the clamping cavity 42, so that the smoke moves up smoothly and the water drips.

[0041] The second treatment mechanism is arranged on the outside of the shell 1, including a treatment box 2 connected by a pipe 3, a liquid spray pipe 8 is arranged in the treatment box 2, and one side of the treatment box 2 is connected to the shell 1 through an air outlet 6 and a liquid outlet tank 7; water is sprayed into the treatment box 2 through the liquid spray pipe 8, contacts the flue gas entering the treatment box 2, and performs the fourth dust reduction treatment; the water flows back to the shell 1 through the liquid outlet tank 7 and gathers in the water collecting tank 45.

[0042] The fan blade 9 is rotatably connected in the treatment box 2, and the fan blade 9 is driven to rotate by a motor (not shown in the figure). The liquid outlet end of the liquid spraying pipe 8 and the gas outlet end of the pipe 3 are both arranged toward the fan blade 9; with the design of the fan blade 9, the water sprayed from the liquid spraying pipe 8 and the smoke flowing out of the pipe 3 act on the fan blade 9 at the same time. While the water cleans the surface of the fan blade 9, the smoke is affected by the airflow driven by the rotation of the fan blade 9, and its small-volume dust particles are also easier to be captured and contacted with the atomized water.

[0043] The air outlet 6 is arranged at the rear side of the fan blade 9 so that the gas passing through the fan blade 9 enters the housing 1 ; the liquid outlet trough 7 receives the water dropped by the fan blade 9 and transports it into the housing 1 .

[0044] The housing 1 is provided with a liquid receiving hopper 5, which is located between the mesh assembly 4 and the liquid outlet tank 7 and above the connection between the pipeline 3 and the housing 1. The liquid flowing out of the liquid outlet tank 7 is collected on the frame and acts on the clamping cavity 42 and the filter membrane 41.

[0045] In order to allow the flue gas passing through the mesh assembly 4 to enter the treatment box 2 through the pipe 3, a liquid receiving hopper 5 is provided to cover the top of the mesh assembly 4, so that the flue gas can enter the treatment box 2 through the pipe 3. At the same time, the liquid flowing out through the liquid outlet 7 is gathered in the liquid receiving hopper 5, and then flows out to the mesh assembly 4 through the outlet at the bottom of the liquid receiving hopper 5; when the water liquid is gathered in the liquid receiving hopper 5, it forms a water seal with the outlet at the bottom of the liquid receiving hopper 5, preventing the water liquid flowing out of the mesh assembly 4 from moving up directly.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
