It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] like Figure 1-4 As shown, a waste gas front-end treatment dehydration cabinet comprises a cabinet body 1 and a filter element 2 and a rotary dehydration module 3 arranged in the cabinet body 1;

[0020] The rotary dehydration module 3 includes a motor 31 and a C-shaped support frame 32, the bottom of the C-shaped support frame 32 is connected to the bottom plate of the cabinet 1, the motor 31 is arranged at the top of the C-shaped support frame 32, the filter element 2 is arranged in the cavity between the top and the bottom of the C-shaped support frame 32, and the bottom end of the filter element 2 is rotatably connected to the bottom of the C-shaped support frame 32, and the top end of the filter element 2 is fixedly connected to the output shaft of the motor 31; the cabinet 1 is provided with a spray head, and the spray head is facing the cavity of the C-shaped support frame 32.

[0021] In the exhaust gas front-end treatment dehydration cabinet, after the filter element 2 is set in the C-shaped support frame 32, the spray head will face the filter element 2, and the filter element 2 will be sprayed through the spray head. After stopping the spraying, the filter element 2 is driven to rotate by the motor 31, and the filter element 2 can be used to rotate and increase the rotation speed; in the process of accelerating the rotation, the filter element 2 can generate a strong centrifugal force external tension, so that the smoke and dust water attached to the surface of the filter element 2 is separated from the filter element 2, so as to achieve the purpose of cleaning the filter element 2. The cleaned filter element 2 can be reused in the exhaust gas front-end treatment to adsorb the smoke and dust water in the exhaust gas, so as to prevent the smoke and dust water from entering the exhaust gas treatment end, so that the activated carbon or fluorite wheel at the subsequent exhaust gas treatment end can treat the exhaust gas alone, so as to extend the working life of the activated carbon or fluorite wheel. In this way, the use cost can be effectively reduced and the burden on the enterprise can be reduced.

[0022] It is worth noting that if Figure 1 As shown, the cabinet 1 further includes a middle partition 4, which is arranged in the cabinet 1 to divide the cabinet 1 into a drying area and a dehydration area, the filter element 2 is arranged in the dehydration area, and the motor 31 is arranged in the drying area. Since there is moisture in the dehydration area, and the motor 31 and other driving mechanisms are electric devices, the middle partition 4 is used to separate the dehydration area, which can protect the motor 31 and other driving mechanisms.

[0023] Optional, such as Figure 1 , 3As shown in FIG. 4 , the middle partition plate 4 is provided with an air outlet 41, and the drying area and the dehydration area are connected through the air outlet 41; the cabinet body 1 is provided with an air inlet 11 and an air outlet 12, and the air inlet 11 is connected through the air outlet 41, and the harmful gas precipitated from the filter element 2 can be discharged by blowing air, so that the filter element 2 can be completely cleaned;

[0024] The C-shaped support frame 32 is further provided with a cylinder 5, the telescopic shaft of the cylinder 5 extends toward the direction of the air outlet 41, and a pressure plate 6 is provided at the end of the telescopic shaft of the cylinder 5 to open or close the air outlet 41. The pressure plate 6 is driven down by the cylinder 5 to close the air outlet 41, so that when the filter element 2 is cleaned, the spray water can be prevented from splashing into the drying area.

[0025] Preferably, Figure 3 and 4 As shown, the middle partition plate 4 is provided with a rubber ring 7, and the rubber ring 7 is arranged around the air outlet 41, and the pressure plate 6 contacts the rubber ring 7 to close the air outlet 41. The rubber ring 7 can improve the sealing performance, and after the air outlet 41 is closed by the pressure plate 6, the high sealing performance is used to prevent leakage.

[0026] Specifically, Figure 2 As shown, the rotary dehydration module 3 also includes a chuck 33 and a chassis 34, wherein the chuck 33 is fixedly connected to the upper end of the filter element 2, the output shaft of the motor 31 is fixedly connected to the chuck 33, the chassis 34 is fixedly connected to the lower end of the filter element 2, and the chassis 34 is rotatably connected to the bottom of the C-shaped support frame 32 through a bearing 35. Specifically, an adjusting screw 36 is provided between the chuck 33 and the chassis 34, the upper end of the adjusting screw 36 is threadedly connected to the chuck 33, and the lower end of the adjusting screw 36 is threadedly connected to the chassis 34, and the height between the chuck 33 and the chassis 34 can be adjusted by the adjusting screw 36, so that the filter element 2 can be clamped and the filter element 2 can be driven to rotate.

[0027] It is worth noting that if Figure 3 and 4 As shown, the filter element 2 further includes a sealing airbag 8, which is disposed on the lower surface of the middle partition plate 4 and faces the chuck 33, so that the sealing airbag 8 contacts the chuck 33 after the sealing airbag 8 is inflated. During spraying, the sealing airbag 8 is inflated and contacts the chuck 33, thereby preventing the filter element 2 from rotating during spraying. In addition, the sealing airbag 8 can also improve the sealing performance, and can further improve the sealing performance when combined with the rubber ring 7.

[0028] The working process of the exhaust gas front-end treatment dehydration cabinet is as follows: before working, stop the machine, install the filter element 2 that needs to be cleaned on each rotary dehydration module 3, and use the chuck 33 and the bottom plate 34 to press the filter element 2. Close the cabinet door and install the cleaning spray liquid required for spraying.

[0029] Start the cleaning control system, at this time, the cylinder 5 drives the pressure plate 6 to descend, the sealing airbag 8 is in an inflated and sealed state, the spray water pump is started, the spray valve is opened, and spraying is carried out. After a period of spraying, the spraying is stopped, the spray valve is closed, and the sealing airbag 8 is deflated and the seal is loosened.

[0030] After spraying, the paint stripping process is started, the rotating motor 31 is started, and the stripping action begins. The motor 31 drives the filter element 2 to rotate at high speed, generating a strong centrifugal force. The smoke and dust water adhering to the filter element 2 are made to fly out. This process is carried out for a period of time, which is preset. After the processing time is reached, the motor 31 slows down and stops. After it stops completely, the cylinder 5 keeps the downward pressure state, and the sealing airbag 8 is inflated and sealed, preparing for the next spraying and stripping. At this time, the interval time is entered, and the spraying and stripping process of the next rotary dehydration module 3 is ready to be started.

[0031] When the interval time is up, the work flow of the next spin dehydration module 3 is started, and its work process is the same as that of the previous spin dehydration module 3. After processing this spin dehydration module 3, the next spin dehydration module 3 is processed, and after processing all the spin dehydration modules 3 in time sharing, the first spin dehydration module 3 is repeatedly processed, and this cycle continues until the processing control system is shut down.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
