Abstract

The utility model relates to a cooking fume purifier. The inner part of the utility model is provided with a liquid storing tank 11, and the upper part of the liquid storing tank 11 is provided with a filter screen impeller 3 which can rotate around a shaft 8. While in use, the inner part of the liquid storing tank 11 is provided with washing liquid; the filter screen impeller 3 which is used for filtering cooking fume rotates around the shaft 8 under the action of air current. Oil dirt which is adsorbed on a filtet screen just now is cleaned in the washing liquid, so as to keep the filter screen clean. The utility model has the advantages of simple structure, low cost, small size, cleanness, small ventilation resistance and small water consumption.

Description

A kind of cooking fume remover

The utility model relates to smoke exhaust, particularly the cooking fume remover of smoke exhaust.

The kitchen fume in hotel, restaurant, dining room, dining room is very big to the influence of environment and human body, and according to relevant department's research, oil smoke has carcinogenesis to human body.Along with the increase day by day in dining room, wineshop, the mist of oil discharging becomes one of main air pollution source in city.Traditional kitchen fume treating method is with air exhauster and pipeline mist of oil to be discharged to outdoor going, and this does not tackle the problem at its root.Moreover this type of air exhauster has destroyed the dynamic balancing of blower fan because greasy dirt gathers, and very easily causes device damage, accumulates in ducted greasy dirt and causes fire easily.

At present, the domestic cooking fume remover of having brought into use, these cooking fume removers can be divided three classes on oil removing mechanism, and the first kind is a washing method, oil smoke is imported in the container that cleaning solution is housed or adopts spraying method that oil smoke is absorbed.This class methods water consumption is big, the flowing resistance height; Second class is to adopt the electrostatic precipitation principle, and elaioleucite is under the effect of high voltage electric field in the oil smoke, and gas is ionized, and oil or fat particles to the oil suction polar motion, and accumulates in and receives on the oil pole under the effect of electric field force.This class methods apparatus expensive, occupied ground is big, and the greasy dirt of receiving on the oil pole is difficult to cleaning; The 3rd class is the dry type filtration method, utilize various filtrates to filtering oil smoke, greasy dirt in the oil smoke when the filtrate attached on the filtrate, filtered purified gas is discharged by blower fan, this class clarifier is simple in structure, easy to use, but greasy dirt very easily sticks on the filtrate, cause filtrate to stop up the clarifier cisco unity malfunction.

The purpose of this utility model is: provide a kind of simple in structure, cost is low, and volume is little, cleaning, and flowing resistance is little, the fume exhaust fan cooking fume remover that water consumption is little.

For achieving the above object, solution of the present utility model is: it is arranged on air exhauster air inlet the place ahead, it comprises shell, air inlet, gas outlet, gas outlet and air exhauster air inlet UNICOM, bottom in the shell is provided with liquid reserve tank, the top of liquid reserve tank is provided with the screen pack impeller that can sway, and the axle two ends are arranged on the outer casing inner wall.

During use, cleaning solution is housed in the liquid reserve tank, during air exhauster work, oil smoke gas enters the utility model clarifier by air inlet; In this clarifier, when oil smoke gas passed through the screen pack impeller, the greasy dirt in the oil smoke gas was filtered net absorption, entered air exhauster by the gas outlet again and discharged.Under the air-flow effect, the screen pack impeller sways, and in the time of in the cleaning solution in impeller turns to liquid reserve tank, the greasy dirt that is adsorbed on the screen pack is cleaned, and can keep filtering net cleaning like this.The utility model is simple in structure, and cost is low, and volume is little, cleaning, and flowing resistance is little, and water consumption is little.

Below in conjunction with accompanying drawing, embodiment is described in further detail to the utility model:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model structural representation.

Fig. 3 is elaioleucite water particle separator 5 structural representations.

Fig. 4 is the A-A cutaway view of Fig. 3.

As shown in Figure 1, 2, the utility model clarifier is arranged on air exhauster 12 air inlet the place aheads, and it comprises shell 1, air inlet 13, gas outlet 14, gas outlet 14 and air exhauster 12 air inlet UNICOMs.Bottom in the shell 1 is provided with a liquid reserve tank 11, in the liquid reserve tank 11 cleaning solution is housed, and the top of liquid reserve tank 11 is provided with and can be with screen pack cylinder 4 on the screen pack impeller 3 around 6 screen pack impeller 3 of axle 8 rotations.Axle 8 two ends are arranged on shell 1 inwall.Have opening on the shell 1 of liquid reserve tank 11 tops,, change cleaning solution with easy disassembly, cleaning impeller 3 and cylinder 4; Be stamped cover plate 2 on the opening.Liquid reserve tank 11 bottom UNICOM-blowoff valves 9; Be provided with electric heater unit 10 in the liquid reserve tank 11.14 places, gas outlet are provided with the elaioleucite water particle separator of being made up of fan aerofoil profile baffle plate 5 (as Fig. 3,4), and separator 5 belows are provided with oil-collecting water leg 6, oil-collecting water leg 6 bottom UNICOMs one return pipe 7, return pipe 7 and liquid reserve tank 11 UNICOMs.

The oil-containing flue gas is under the effect of air exhauster 12, enter the utility model from air inlet 13, oil smoke gas has been realized the one-level filtration through filtering oil smoke cylinder 4 (cylinder 4 screen pack density are the 10-30 order), realized the cascade filtration of oil smoke again by filtering oil smoke flabellum plate 3 (impeller 3 screen pack density are the 30-50 order), oil smoke behind cascade filtration moves forward and passes through three grades of oil removing mechanism elaioleucite water particle separators 5, under its effect, air-flow produces water particle that elaioleucite and impeller 3 in the strong centrifugal swirling eddy take out of to be separated with flue gas under the action of centrifugal force that separator 5 produces and is thrown toward oil-collecting water leg 6 and collects, the waste liquid of collecting flows in the liquid reserve tank 11 through return pipe 7, has finished three grades of oil removing processes thus.

The utlity model has following characteristics: 1, for preventing from filtering lower greasy dirt in screen pack cylinder 4 and filtration Bonding on the net impeller 3 is stopped up the normal use that wire side affects cooking fume remover, and screen pack of the present utility model rolls The Lower Half of tube 4 and impeller 3 is immersed in the cleaning solution of liquid reserve tank 11, promotes impeller under the effect of air-flow 3 rotate and drive screen pack cylinder 4 rotates, and makes the greasy dirt that just is filtered under the net filtration enter into cleaning case Be washed the liquid dissolving, after the greasy dirt that dissolves in the cleaning solution reaches capacity state, discharge by blowoff valve 9; 2, Cleaning fluid freezes when preventing winter, is provided with heater in casing, and is certain to guarantee that cleaning fluid remains on Temperature range, thus clean result improved; 3, three grades of oil removing mechanism elaioleucite water particle separators 5 are by the aerofoil profile baffle plate Form, it can not only play the effect of oil removing, but also oil, water can be separated with gas, and by the oil-collecting collection Tank 6 takes off the oil in the air-flow, moisture to the greatest extent, thereby has avoided the water spray phenomenon of general wet cleaner air outlet.
