Abstract

The utility model relates to a cooking oil fume purifier. A plurality of layers of overlapped water curtain plates are fixed on the lower part of a housing, and the clearances of adjacent water curtain plates form oil fume inlets. A sieve plate is arranged above the water curtain plates, and the inner side of the sieve plate is provided with a water inlet pipe. A water collecting tank is arranged on the low-side of the water curtain plates, a silk screen plate is installed above the sieve plate, and a blower fan is fixed above the housing. The purifier is suitable for kitchens in catering industry which generate large amounts of oil fume. Oil fume gases can be washed, filtered, and purified, and the purifying rate is high. Just like a normal domestic oil fume exhauster, the utility model has the advantages of simple and convenient installation and operation.

Description

The cooking fume clearing machine

The utility model relates to the purifier of cooking fume.

The purifying rate of household smoke exhaust ventilator is low, and the cooking fume amount that hotel, restaurant, canteen produce is big, is unsuitable for adopting family expenses formula smoke exhaust ventilator to arrive oil smoke discharge outdoor simply.The method of the cooking fume of catering industry processing at present has: 1. utilize blower fan that oil smoke is forced to be evacuated to high altitude discharge.2. with blower fan oil smoke is concentrated and guided to the purifying column processing.3. adopt electrostatic means to separate mist of oil.4. adopt water spray washing mode to handle.These modes of handling oil smoke all have shortcoming.As, high altitude discharge need be built very high blast pipe, not only constructional difficulties, cost height but also to influence building attractive in appearance.High altitude discharge is purifying oil fume not, but its harmful substance and smell contaminated environment still.Adopt electrostatic method to separate mist of oil, energy consumption is big, and flue gas is short dead time in electric field, separates not exclusively, can't remove smell.Adopt purifying column or water spray mode to handle, occupation of land is many, cost height, difficult management.In addition, the whole bag of tricks all makes without the soot gas that purifies and passes through blower fan, and its oil, water smoke are condensed on the blade of blower fan, clean difficulty, have increased the maintenance work amount of equipment.

The purpose of the utility model is to provide a kind of fume purifying rate height, installation, easy to operate, and lower-cost cooking fume clearing machine.

Cooking fume clearing machine described in the utility model, blower fan is fixed on housing top.Lower housing portion is the multilayer water curtain plate fixedly, adjacent water curtain plate edge is staggered to be taken mutually but does not link to each other, slit between the adjacent water curtain plate constitutes the oil smoke air inlet, the sieve plate of water curtain plate upper fixed porous, water inlet pipe is equipped with in the sieve plate inboard, the water curtain plate side-lower has the water leg of band drainpipe, and silk screen layer is equipped with in the sieve plate top.

When described cooking fume clearing machine is worked, inject washings from water inlet pipe, water covers sieve plate.Air-breathing above sieve plate because of blower fan, sieve plate top produces negative pressure, then soaks to overflow can (or few) not leak down from the sieve plate hole at the water on the sieve plate, and water covers sieve plate and flows on the top water curtain plate and successively flow down, at oil smoke air inlet formation cascade.Cooking fume enters process washing for the first time in the housing through cascade, then by the sieve plate hole upwards, soaks casual water layer on the stirring sieve plate and forms the foamed cleaning layer.Oil smoke through twice washing has been removed oarse-grained mist of oil and dust, again by silk screen layer, through absorption, collision, condensation, coarse effect remaining mist of oil is separated.Purified gas discharges behind blower fan.

Described cooking fume clearing machine makes oil smoke through twice washing, once filtration, and the purifying rate height is through test oil smoke purifying rate 〉=95%.Just by blower fan, no longer include mist of oil substantially and be condensed on the blower fan after oil smoke purifies earlier, reduced the workload of corrective maintenance.This machine can directly be installed on cooking stove top, and purified gas need not high altitude discharge, can reduce construction costs and difficulty of construction, and the installation of this clearing machine, operation are simple and convenient as the normal domestic use smoke exhaust ventilator.

Fig. 2 is that the A-A of Fig. 1 analyses and observe;

The cutaway view of a kind of smoke purifier of Fig. 3;

Fig. 4 is that the B-B of Fig. 3 analyses and observe.

Embodiment one, as Fig. 1,2

Three layers of water curtain plate 9 are fixed in housing 1 bottom, adjacent water curtain plate 9 edges are staggered to be taken mutually but does not link to each other, slit between the water curtain plate 9 constitutes oil smoke air inlet 10, water curtain plate 9 upper fixed porous sieve plates 6, water inlet pipe 5 is equipped with in sieve plate 6 inboards, and the water that flows out from water inlet pipe can soak casual sieve plate 6, for guaranteeing that current soak casual sieve plate equably, the fixing cofferdam plate 4 on water inlet pipe 5 next doors can overflow water equably.For guaranteeing to contain the not short circuit of air-flow of oil smoke, the fixing gas sealing plate 11 respectively at edge that sieve plate 6 and top water curtain plate 9 are taken friendship mutually, water can accumulate between two gas sealing plates 11 with the short circuit of shutoff air-flow, crosses sieve plate to guarantee air communication.Water curtain plate 9 side-lowers have the water leg 7 of band drainpipe 7a.Slurry can be released by drainpipe, is pumped in the water inlet pipe 5 by water pump to recycle again.Silk screen layer 3 is equipped with in sieve plate 6 tops, and blower fan 2 is fixed on housing 1 upper end.

Embodiment two, as Fig. 3,4

Fixed combustion waste gas flue 8 in the water leg 7, flue 8 tops have taper to hide 8a, and the flue other end can link to each other with cooking stove burnt gas exhaust outlet.The washings that flow down from water curtain plate 9 flow down from hiding the 8a periphery, form cascade, make the waste gas of burning also purify the back discharge via this clearing machine.

Fixedly utilize the water tank 12 of waste heat outside the flue 8, water level controller 13 is housed in the water tank, water tank has heat supply water pipe 14.Water tank can utilize the waste heat of burnt gas.
