Description

Technical Field

[0001] The utility model relates to a purification device, in particular to a high-voltage electrostatic oil fume and dust purification device, belonging to the technical field of oil fume purification. Background Art

[0002] With the increasingly strict national and social environmental protection requirements, higher standards for pollution control are required in many places, especially for oil fumes, soot, etc., such as kitchen oil fumes in large places, soot from food frying and cooking processes, and oil dust in processing places (such as oil splash heat treatment, oil mist lubrication, boiler workshops, etc.). Electrostatic purifiers are devices that use the principle of high-voltage static electricity to purify oil fume and dust, and they are currently the mainstream purification devices. Oil fume (dust) is sucked into the electrostatic oil fume purifier by a fan. Some of the oil mist and oil dust particles are captured on the uniform flow plate due to mechanical collision and retention; under the action of the high-voltage electric field, the oil mist is charged and decomposed and carbonized, and the positive and negative plates capture it, thereby completing the purification.

[0003] Among them, the "efficient electrostatic oil and dust removal device" disclosed in the patent application number "202022483922.6" "comprises an air inlet pipe, a filter box, and an air extraction system that are sequentially sealed and connected along the left and right flow directions of the air flow; a uniform flow plate, a filter screen, and an electrostatic oil fume purifier are sequentially arranged in the filter box along the air flow direction; the uniform flow plate is sequentially a middle section, a transition section, and an outer edge section from the center to the periphery. The middle section is an arc-shaped structure in the shape of a spherical crown, which protrudes towards the air inlet direction. The outer edge section is a straight structure, and the transition section is a smooth arc section connecting the middle section and the outer edge section; a groove body penetrating the plate body is laid on the uniform flow plate. The groove body in the middle section is a plurality of groups of arc-shaped grooves, and the plurality of groups of arc-shaped grooves in the middle section are dispersed outward from the center of the middle section in a turbine shape.
