Examples

As shown in fig. 1-3, a novel range hood for improving the odor purification rate of smoke, like a conventional range hood, comprises a main cabinet 1, a fan 2 and a purifier 3. Fan 2 and clarifier 3 set up in mainframe box 1 top, and fan 2 is used for as the power supply of mainframe box 1 suction oil smoke, and clarifier 3 is used for carrying out primary purification treatment to the oil smoke after the suction. The front panel 7 of mainframe box 1 is close to the oil smoke and takes place the position, and inside filter equipment and the oil groove 4 of being equipped with of mainframe box 1, filter equipment from inside to outside in proper order including purifying rim plate 5 and oil drain comb 6, purify rim plate 5 and fix inside mainframe box 1, oil groove 4 is used for receiving the oil drop that filters and drip. Purify rim plate 5, the theory of operation of oil drain comb 6 and its concrete structure all are the mechanism that traditional lampblack absorber was used always, so the utility model discloses do not do again to its concrete structure here and describe, and fan 2 and clarifier 3 also all are the structure that the lampblack absorber was used always, all can purchase on the market, consequently do not again describe again to its concrete structure here again.

The difference is, traditional lampblack absorber carries out oil through purifying rim plate 5, the flue gas after the cigarette is handled can directly get into and carry out the follow-up purification of flue gas in the clarifier 3, but the oil gas this moment still has the high temperature, in long-term in the past, the flue gas can cause the high temperature damage to clarifier 3, and has the peculiar smell in the flue gas, be not convenient for fall in the clarifier in the processing for exhaust flue gas still has the peculiar smell, so the utility model discloses flue gas water treatment facilities have been added for flue gas after purifying rim plate 5 is after water treatment, in the rethread clarifier 3, guarantee the stable use of whole lampblack absorber when improving purification efficiency.

Specifically, flue gas water treatment facilities is including setting up the water tank 8 in the middle of purifying rim plate 5, and water tank 8 is fixed with the plane that purifies rim plate 5 place, and its top separates with mainframe box 1 top, is equipped with the clearance between the two promptly, and the flue gas through purifying rim plate 5 can pass into in water tank 8 through this clearance then. The oil tank 4 is provided with a water inlet and a water outlet, the water tank 8 is connected with the water inlet and the water outlet through a water conveying pipe, the water inlet is connected with an external water source, so that a water source can be conveyed into the water tank 8, and the water outlet is connected with an external drainage part, so that waste water in the water tank 8 can be output. A ball float valve is further arranged in the water tank 8 to ensure the liquid amount in the water tank 8. The top of water tank 8 is equipped with sprays the installing zone, sprays the installing zone and comprises square iron stand 81, and it is located mainframe box 1 top below. The inside a plurality of shower nozzles that are equipped with of square iron stand 81, the nozzle of shower nozzle all inside towards water tank 8. The spray heads are connected by a shunt pipe which is supplied by a main water pipe connected with a water pump 82 arranged in the water tank 8. Then the water pump 82 is opened, and the water in the water tank 8 can be pumped to the main water pipe, so that water is obtained in each spray head, and the spraying work can be carried out, thereby carrying out water treatment cooling on the flue gas entering the water tank 8. The shower nozzle adopts the current shower nozzle that can spray water now can, it has a large variety of implementation structure, just the utility model discloses do not improve its structure, consequently do not do the perusal again to its specific structure here.

Further, flue gas water treatment facilities still includes the filtering component 9 that sets up at clarifier 2 front end, and filtering component 9 is used for carrying out filtration treatment to the flue gas after water treatment, avoids it to carry during steam gets into clarifier 3. The filter assembly 9 is arranged at the top of the mainframe box 1 and positioned at the air inlet of the purifier 3, and comprises two groups of filter screens which are arranged in an L shape, wherein each filter screen is composed of a plurality of layers of steel meshes so as to form an intensive filtering area. Wherein a set of filter screen transversely sets up in the upper surface department at mainframe box 1 top, and the flue gas in the mainframe box 1 of being convenient for carries out primary filtration through this filter screen, avoids during flue gas steam gets into post processing apparatus, and the vertical setting of another group filter screen is in the import of clarifier 3 to carry out secondary filter to the flue gas that gets into clarifier 3, further carry out the filtration of steam to the flue gas after water treatment, in order to avoid it to bring the influence to clarifier 3.

Furthermore, a baffle plate 91 inclined towards the direction of the water tank 8 is arranged below the filtering component 9, one end of the baffle plate is connected with the side wall of the main case 1, and the other end of the baffle plate is fixed with the square iron frame 81 of the spraying installation area. The baffle 91 is spaced from the filter assembly 9 by a distance, i.e. a gap is provided between the two for the flue gas to flow through. And the surface of the baffle 91 above the water tank 8 is provided with a through hole 92.

When the range hood is used, oil drops of cooking oil smoke generated by cooking are treated through the purification wheel disc 5, smoke generated after oil and gas separation rises in the main case 1, and the smoke enters the water tank 8 through a gap between the water tank 8 and the top of the main case. And the nozzle in the spray installation area of the upper part of the water tank 8 can discharge water to spray the flue gas passing through the water tank 8, after spraying, the temperature of the oil flue gas and the peculiar smell of the oil flue gas can be reduced, the flue gas output from the purifier 3 is prevented from having peculiar smell and influencing the air, and the flue gas entering the purifier 3 at the later stage can be prevented from having higher heat, so that the temperature in the purifier 3 is prevented from being overhigh, and the normal work of the purifier 3 is influenced.

The flue gas after water treatment continues to move towards the purifier 3 because of the suction force brought by the purifier 3, namely, the flue gas moves towards the filtering component 9. The flue gas firstly carries out primary filtration through the horizontal filter screen that is located the bottom, and the drop of water that the flue gas has after the water treatment can be blocked by the filter screen, and it is attached to on the filter screen in a large number, and it is after condensing into the water droplet, because the reason of gravity directly falls to the baffle 91 department of filter assembly 9 below, and the flue gas rethread vertical filter screen that carries out primary filtration carries out secondary filtration to avoid it to have steam to influence the work of clarifier 3. Further, because the baffle 91 is inclined toward the water tank 8, water drops on the surface of the baffle 91 flow along the inclined direction of the baffle 91, and the water on the surface of the baffle 91 can directly drop into the water tank 8 below through the through hole 92 arranged on the baffle 91 during the flow process, so that excessive water accumulation on the surface of the baffle 91 is avoided.

Parts not described in the above modes can be realized by adopting or referring to the prior art.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
