Description

Water condensation spraying exhauster for removing cooking fumes

The utility model relates to the oily fume exhauster that is attached on the kitchen range.

The range hood of present family widespread usage, kitchen fume and pernicious gas have been worked to purify to a certain extent, but because its structural limitation, purification effects is unsatisfactory, it is only simple with oil, cigarette, gas is through the suction of pneumatic source blower fan and be discharged from, have only the elaioleucite of running into the cover wall on a small quantity to be collected in the lubricating cup, and that major part is discharged from is outdoor, these are not subjected to the tobacco tar of purified treatment and the pollution sources that pernicious gas becomes ambient atmosphere on the contrary, the elaioleucite that is condensed on the cover wall for part becomes greasy because of not most fuel particles and the flue dust of burning in the continuation absorption oil gas, and develop into oil clot, in case these are block greasyly to fall on dish or in the food, just causes diet to pollute.Because clean-up effect is poor, do not play the effective measures of kitchen environment protection, particularly be applied on the bigger cooking stove of hotel, public organization or the catering trade, effect is poorer.On the other hand, the cleaning of lampblack absorber inwall is also very inconvenient.

The purpose of this utility model is to overcome the defective of prior art and provides a kind of collection rate and purifying rate very high water condensation spraying type range hood, this oil smoke function is the oil smoke dirt in the separating oil flue gas effectively, reaches further purification kitchen environment and purify the purpose of outside atmosphere.

The utility model is achieved by the following scheme, promptly at housing, exhaust outlet, the blast pipe of former range hood, be located on the architecture basics of the blower fan outside the wall and set up Oil-gas Separation mechanism and spraying mechanism.

Oil-gas Separation mechanism comprises that the waveform coldplate of oblique setting and arrangement parallel to each other, lattice shape are divided water plate and drainage mechanism from oil row, chevron, in order to realize Oil-gas Separation.Spraying mechanism has a sparge pipe that has a plurality of ostium excurrenses, and running water ejects countless droplets by water inlet through sparge pipe and forms the cascade barrier under the hydraulic pressure effect, realizes oil smoke condensation and discharges collection.

This lampblack absorber is compared with known technology; thoroughly changed traditional version; utilize Oil-gas Separation mechanism and spraying mechanism to a large amount of oil smoke of being produced in the kitchen, and imperfect combustion exhaust combustion gases realize that the oil gas initial gross separation separates fully after condensation; make oil smoke and harmful substance enter water separation tank; and be discharged into outdoor through the innocuous gas of filtration, purification; after tested; profit gas isolation of purified rate reaches more than 98%; not only having alleviated air environmental pollution, is the effective measures that realize the kitchen environment protection simultaneously.This machine is because blower fan is located at wall outward away from working host, so noise is little, has further improved the noise pollution of cooking working environment.

Description of drawings.

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A cutaway view of Fig. 1.

In conjunction with above-mentioned accompanying drawing embodiment of the present utility model is described in further detail.

The housing of water condensation spraying type range hood (seeing Fig. 1-2) is welded into chamber part in addition mutually by outer cover (2), the biside plate (13) of sheet metal system, the support (8) that is pressed into grooved, outer cover (2) end face is provided with exhaust outlet (1), blower fan is located at outside the wall, connects exhaust outlet (1) and blower fan (not shown) by blast pipe.Oil-gas Separation mechanism and spraying mechanism are housed in the housing cavity.

Oil-gas Separation mechanism comprises that the waveform coldplate (3) of oblique setting and arrangement parallel to each other, lattice shape are divided water plate (10) and drainage mechanism from oil row (9), chevron.Waveform coldplate (3) is for being folded into corrugated thin plate, and its two ends and hanging feet (6) are fixing, and hanging feet is fixed on again on the outer cover (2) and support (8) of housing.Lattice shape is located in the special-shaped groove (7) from oil row (9), and special-shaped groove (7) is fixed on the outer cover (2) and support (8) of housing, and the special-shaped groove (7) of lower end has through hole.Lattice shape according to lampblack absorber overall length needs, can become " one " font assembled arrangement from oil row (9) by a plurality of frameworks (15), framework upper and lower open-minded, be equipped with in the framework a plurality of upper and lower mutual dislocation and arrange in opposite directions "

" shape baffle plate (14), the two ends of baffle plate (14) and framework (15) are fixing.Chevron divides water plate (10) to be fixed on the shell holder (8), is linked to be by the plane is alternate with the waveform curved surface, lattice shape is set links up mutually with it from the through hole of oil row's lower end abnormity groove (7).The water leg of drainage mechanism (11) is in its below and its communication, and delivery port (12) is fixed on water leg (11) below, and it communicates with outdoor water separation tank (not shown).

Spraying mechanism comprises the water inlet (4) that is arranged on outer cover (2) end face two ends, and this water inlet (4) is linked up mutually with the sparge pipe that has a plurality of ostium excurrenses (5), and sparge pipe (5) is fixed on the housing cavity top.

Fixing can the welding between each other part of the utility model can also connect by screw.

The draft that oil gas, oil smoke and the imperfect combustion exhaust combustion gases that produces when the kitchen oil cauldron is subjected to blower fan sucks outer cover (2) inner chamber through lattice shape during from oil row (9), because the baffle plate (14) that dislocation is also arranged in opposite directions in the framework (15), make floating oil gas complications be subjected to resistance in advancing, this has just increased the collision between elaioleucite and the baffle plate (14), make oil smoke obtain initial gross separation, the oil droplet that drops down divides water plate (10) through the through hole inflow chevron of lower end abnormity groove (7).

When in being continued, walking to waveform coldplate (3) by the oil smoke of initial gross separation, because the cascade barrier that spraying mechanism forms, elaioleucite condensation in the oil smoke of high temperature is built up on the corrugated sheet face taken advantage of a situation and swept away by cascade absorption, drip is gone into chevron and is divided water plate (10), because chevron divides water Lamb wave shape wave curved surface that current are concentrated in a large number, flow velocity is greater than the elaioleucite of keeping afloat, thereby the water leg (11) that makes the further gathering of elaioleucite flow to drainage mechanism together is discharged into water separation tank through delivery port (12), when the high outlet actinal surface of the noodle in the separator box, oil promptly overflows and is collected.And the innocuous gas after above-mentioned processing has been filtered purification, under the draft of the blower fan of bleeding, discharge outdoor, thereby administered the pollution sources of ambient atmosphere.

The effect of spraying mechanism not only makes oil smoke fully adsorb and sweeps away, and has separated the oil smoke dirt in the oil smoke gas effectively, has also cooled off oil smoke simultaneously, has eliminated pollution and peculiar smell, has improved the cooking working environment greatly.
