Description

Technical Field

[0001] The utility model belongs to the technical field of smoke exhaust, and particularly relates to a smoke exhaust device with a filtering function. Background Art

[0002] At present, there are various oil fume purification and exhaust devices on the market, mainly including electrostatic oil fume purifiers, mechanical filtration oil fume purifiers, photocatalytic oil fume purifiers, and composite oil fume purifiers, etc.

[0003] However, with the increase of the use time, the grease in the oil fume will gradually accumulate on the purification components such as the plasma adsorption plate, forming a thick grease layer. This grease layer will not only affect the passage of the oil fume, but also hinder the further adsorption and purification of fine particles. The adsorption capacity of the purification components such as the plasma adsorption plate is limited. When the adsorbed grease and particles reach a certain amount, they will reach a saturated state and can no longer effectively adsorb new oil fume particles. At this time, the cleaning and maintenance cost of this structure will increase greatly.

[0004] Therefore, aiming at the above-mentioned existing smoke exhaust devices, because the grease aerosol in the oil fume contains a large number of insoluble large particles, these large particles will be adsorbed on the plasma adsorption plate, hindering the continuous adsorption and purification of the fine particles of the smoke, resulting in the problem that the oil fume filtration and purification gradually fails with the increase of the use time, a smoke exhaust device with a filtering function can be designed. Content of the Utility Model

[0005] In order to overcome the problems of the existing smoke exhaust devices, because the grease aerosol in the oil fume contains a large number of insoluble large particles, these large particles will be adsorbed on the plasma adsorption plate, hindering the continuous adsorption and purification of the fine particles of the smoke, resulting in the problem that the oil fume filtration and purification gradually fails with the increase of the use time.

Because the surface of the oil-repellent coating plasma electrode plate group has an oil-repellent film, the adsorbed and condensed oil beads fall into the oil collecting box under the action of gravity, and then fall into the oil collecting tray from the oil collecting box for collection, thereby realizing the functions of filtering, adsorbing, and collecting oil fume, and effectively improving the efficiency of oil fume purification; the filtering component includes an aluminum frame and a flue gas filter plate; aluminum frames are arranged on both sides of the purification component, and the aluminum frames are connected to the inner wall of the flue gas purification chamber through card slots; the splicing connection method of the flue gas filter plate in the aluminum frame sandwich effectively improves the installation efficiency of the flue gas filter plate and reduces the maintenance cost, effectively filters insoluble coarse particles, and prolongs the service life of the oil-repellent coating plasma electrode plate group.

[0007] Preferably, the flue gas filter plate of the filtering component preliminarily filters the coarse particles in the oil fume, thereby effectively preventing insoluble coarse particles from occupying the effective adsorption area of the oil mist of the oil-repellent coating plasma electrode plate group, and effectively prolonging the oil mist adsorption life of the oil-repellent coating plasma electrode plate group, solving the problem of existing smoke exhaust equipment that, because the oil fume mist contains a large amount of insoluble large particles, these large particles will be adsorbed on the plasma adsorption plate, hindering the continuous adsorption and purification of fine smoke particles, resulting in the gradual failure of oil fume filtration and purification with the increase of use time.

[0008] As a preference, an oil collecting box is arranged below the oil-repellent coating plasma electrode plate group, and the oil collecting box is fixedly sealed to the lower port of the flue gas purification chamber through bolts, and there are vertically penetrating oil discharge holes arranged inside the oil collecting tray; an oil collecting tray is arranged below the oil collecting box, and the oil collecting tray is placed along the inner wall chute of the flue gas purification chamber.

[0009] Preferably, the aluminum frame is composed of two aluminum frames spliced together; a flue gas filter plate is clamped inside the splicing part of the frame of the aluminum frame, and the flue gas filter plate is a high-temperature resistant air particulate filter plate; the thick particulate matter in the oil fume is preliminarily filtered by the flue gas filter plate of the filtering component, thereby effectively preventing insoluble coarse particulate matter from occupying the effective oil mist adsorption area of the oil-repellent coating plasma electrode plate group, and effectively extending the oil mist adsorption life of the oil-repellent coating plasma electrode plate group.

[0010] Preferably, the control component includes a control panel, a cooling fan, and an electric controller; a control panel is arranged on the front end face of the flue gas purification chamber, and the control panel is hingedly connected to the flue gas purification chamber; a cooling fan is arranged inside the control panel.

[0011] Preferably, an electric controller is arranged behind the cooling fan, and the electric controller is fixedly connected to the inner wall of the control panel and is electrically connected to the electrical equipment.

[0012] Advantages of the present utility model:

[0013] In the existing smoke exhaust equipment, because there are a large number of insoluble large particulate matters in the oil mist of the oil fume, these large particulate matters will be adsorbed on the plasma adsorption plate, hindering the continuous adsorption and purification of the fine particulate matters in the smoke, resulting in the problem that the oil fume filtration and purification gradually fails with the increase of the use time; the thick particulate matters in the oil fume are preliminarily filtered by the flue gas filter plate of the filtering component, thereby effectively preventing insoluble coarse particulate matter from occupying the effective oil mist adsorption area of the oil-repellent coating plasma electrode plate group, and effectively extending the oil mist adsorption life of the oil-repellent coating plasma electrode plate group; solving the problem of the existing smoke exhaust equipment, because there are a large number of insoluble large particulate matters in the oil mist of the oil fume, these large particulate matters will be adsorbed on the plasma adsorption plate, hindering the continuous adsorption and purification of the fine particulate matters in the smoke, resulting in the problem that the oil fume filtration and purification gradually fails with the increase of the use time;

[0014] Through the setting of the purification component, when the oil fume first passes through the flue gas filter plate to filter the coarse particulate matters, the oil fume mist molecules are charged under the action of the oil-repellent coating plasma electrode plate group, and are adsorbed by the oil-repellent coating plasma electrode plate group under the action of electrostatic adsorption. Because the surface of the oil-repellent coating plasma electrode plate group has an oil-repellent film, the adsorbed and condensed oil beads fall into the oil collecting box under the action of gravity, and then fall into the oil collecting tray from the oil collecting box for collection, thereby realizing the functions of filtering, adsorbing and collecting the oil fume, and effectively improving the efficiency of oil fume purification.
