[0050] The working principle of this embodiment is described in detail as follows:

[0051] In this embodiment, this product is a dry filter. Taking the installation of this product in a water transport hood as an example, the water transport hood is started and starts working. Under the push of the wind force generated by the exhaust fan in the water transport hood, a pressure difference is formed between the air inlet and the air outlet, so that the oil fume cutting mesh disk 31 and the vortex impeller blades 32 rotate around the installation shaft 50 under the action of the rotating shaft 20, and the rotation forms a multi-layer dynamic screen net and performs multi-layer dynamic interception of liquid particles such as oil fume, water mist, and waste gas in the exhaust gas under the mixing action of centrifugal force. The intercepted liquid particles such as oil fume, water mist, and waste gas are purified under the action of the lower sink of the water transport hood, UV lamp, etc.

[0052] like Figure 6-Figure 8 As shown, it is a second preferred embodiment of the present invention. The basic structure of this embodiment is the same as that of the first preferred embodiment, and the difference is that:

[0053] There are two mounting plates 22, which are arranged on the main shaft 21 at intervals. The oil fume cutting net disk 31 is installed on the lower mounting plate 22; a cutting plate 91 for physical cutting is locked on the upper mounting plate 22, and the cover 64 is locked in the center of the upper surface of the cutting plate 91 and seals the upper end of the main shaft 21. The cutting plate 91 is punched to form an inclined plate 911 and a punching hole 912 for each vortex impeller blade 32, and the punching hole 912 is located on the side of the inclined plate 911; and the housing 10 is provided with a nozzle 92 for spraying water into the installation space 101. The setting of the cutting plate 91 meets the requirements of centrifugal force and physical cutting. At the same time, the design of the cutting plate 91 increases the weight, so the water sprayed by the nozzle 92 generates hydraulic force on the cutting plate 91, thereby achieving the mixed use of hydraulic force and hydraulic force, and the rotation speed is greatly improved.

[0054] This implementation works as follows:

[0055] The present embodiment is a wet filter. Taking the installation of the product in a water transport hood as an example, the water transport hood is started and begins to work. The product is driven by the wind force generated by the exhaust fan in the water transport hood, and the wind force physically cuts the cutting plate 91. At the same time, the nozzle 92 sprays water at high pressure. Driven by the combination of wind and water force, the oil fume cutting mesh disk 31, the vortex impeller blades 32 and the cutting plate 91 rotate at high speed. The high-speed rotation generates a large centrifugal force, thereby achieving centrifugal and dynamic cutting and filtering of oil fume grease tiny particles, and the high-pressure water spray generates a water mist system, which performs water mist filtration. At the same time, the water can also cool the high-temperature outer shell 10, and the dirt after centrifugation and cutting is brought into the circulating water tank of the water transport hood by water for filtration and can continue to be recycled, thereby meeting the requirements of environmental protection and energy saving.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
