Abstract
The utility model discloses a fume exhauster with a spraying cleaning filter, which comprises a centrifugal fan (2) and a liquid spraying head (4) arranged on the centrifugal fan (2). The utility model is characterized in that an outlet (15) of the centrifugal fan (2) is communicated with an air duct (5) at the lower part of a chassis (1), and a demisting curved plate component (6) is arranged at the middle part of the chassis (1). A fine filter screen (7) is arranged above the demisting curved plate component (6) in the chassis (1), and an adsorbing filter layer (8) is arranged above the fine filter screen (7) in the chassis; an air outlet (9) is arranged on at least one side surface at the upper part of the chassis (1), and an oil and water guide outlet (11) is arranged at the lower part of the chassis (1). The utility model is a fume exhauster having the advantages of simple structure, high oil removing purifying efficiency and self cleaning in the fume exhauster.
Description
Technical field:
The utility model relates to a kind of lampblack absorber of tool spray washing filter.
Background technology:
The kitchen exhaust gas discharged in current family, catering trade, canteen is more and more serious to the pollution of urban air, and is also more and more higher for the requirement of environmental quality along with being showing improvement or progress day by day of society, and the control of cooking fume discharging has also placed on the agenda.Country had issued state environment protecting standard-cooking fume discharge standard GWBP5-2000 in 2000.Wherein stipulated the highest permission concentration of emission≤2.0mg/m of oil smoke
3, purification facility is removed the scope that efficient is not less than 60%-85% to oil smoke minimum.
Gong Ying range hood has several classes in the market, and a kind of is simply oil smoke directly to be discharged into outdoor ventilation fan; A kind of is to utilize the high speed centrifugation agency part that oil smoke is removed discharging; Also having a kind of is that oil cleaner screen is set, and part is removed discharging with oil smoke.These modes are except existing except that the oil smoke poor effect, polluting outdoor air, oil smoke and adhere in the machine not the defective such as easy cleaning, and the overwhelming majority can not reach the oil smoke discharge standard of stipulating in the GWBP5-2000 standard.This is the difficult problem of pendulum in face of the environmental protection personnel.Chinese patent ZL01235178.4 discloses " lampblack absorber that the wash spray device is arranged ", this patent disclosure a kind of at the other lampblack absorber that jet head is housed of centrifugal blower fan blade wheel, jet head is water spray on centrifugal blower fan blade wheel, carry out separation of liquid gas and washing, have the not high and bigger defective of resistance of oil removing purification efficiency.
Summary of the invention:
Technical problem to be solved in the utility model provides the lampblack absorber of self-cleaning in a kind of simple in structure, oil removing purification efficiency height, the machine.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the outlet that is provided with the centrifugal blower of jet head is communicated with air channel, cabinet bottom, be provided with demist winding sheet assembly at the cabinet middle part, be provided with the fine filtering net above the demist winding sheet assembly in cabinet, the online side of fine filtering is provided with the adsorption filtration layer in cabinet; Be provided with air outlet at least one side, cabinet top, be provided with the profit export mouth in the cabinet bottom.
As improvement of the present utility model, be hinged with outstanding cover plate at the cabinet air outlet, be provided with the wind-guiding dividing plate that have oil guiding hole corresponding in the cabinet bottom with the air channel.
As further improvement of the utility model, be provided with the oil guide groove of guiding cabinet sidewall in every winding sheet bottom of demist winding sheet assembly.
Adopt the lampblack absorber of technique scheme, during work, the waste gas that contains the oil smoke mist is sucked by centrifugal blower, jet head is to the centrifugal blower fan blade wheel water spray, water smoke washs the soot gas that is sucked by blower fan, the water smoke mist of oil is subjected to action of centrifugal force, part forms liquid and flows into the cabinet bottom along the centrifugal blower inwall, derive cabinet through the profit export mouth, contain trickle oil smoke mist, the waste gas of water smoke enters demist winding sheet assembly through the air channel, at this trickle oil smoke mist, water smoke and demist winding sheet assembly collide and are attracted on the winding sheet, accumulation forms drop and flows into the cabinet bottom, outside profit export mouth derivation machine, gas through twice purification moves on by the fine filtering net, the adsorption filtration layer further is cleaned, thereby makes the gas of finally being discharged by air outlet reach the oil smoke discharge standard of stipulating in the GWBP5-2000 discharge standard fully, so the utility model is a kind of simple in structure, oil removing purification efficiency height, the lampblack absorber of self-cleaning in the machine.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 be among Fig. 1 A-A to cutaway view.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, the outlet 15 that is provided with the centrifugal blower 2 of jet head 4 is communicated with air channel, cabinet 1 bottom 5, be provided with demist winding sheet assembly 6 at cabinet 1 middle part, be provided with the oil guide groove 13 of guiding cabinet 1 sidewall in every winding sheet 14 bottoms of demist winding sheet assembly 6, in cabinet 1, be provided with fine filtering net 7 above the demist winding sheet assembly 6, the order number of fine filtering net 7 is 100～400, be provided with adsorption filtration layer 8 in cabinet 1 above the fine filtering net 7, adsorption filtration layer 8 is active carbon, molecular sieve or other sorbing materials; Be provided with the air outlet 9 that is hinged with outstanding cover plate 10 at least one side, cabinet 1 top, be provided with profit export mouth 11 and the wind-guiding dividing plate 12 that have oil guiding hole 16 corresponding in cabinet 1 bottom with air channel 5.
During the work of this lampblack absorber, the waste gas that contains the oil smoke mist is sucked jet head 4 to centrifugal blower fan blade wheel 3 water sprays by centrifugal blower 2, water smoke washs the soot gas that is sucked by centrifugal blower 2, the water smoke mist of oil is subjected to action of centrifugal force, part forms liquid and flows into cabinet 1 bottom along centrifugal blower 2 inwalls, oil guiding hole 16 through wind-guiding dividing plate 12, profit export mouth 11 is derived cabinet 1, contain trickle oil smoke mist, the waste gas of water smoke 5 enters demist winding sheet assembly 6 through the air channel, at this trickle oil smoke mist, water smoke and demist winding sheet assembly 6 collide and are attracted on the winding sheet 14, accumulation forms drop and flows into cabinet 1 bottom through oil guide groove 13, outside profit export mouth 11 derivation machines, gas through twice purification moves on by fine filtering net 7, adsorption filtration layer 8, further be cleaned, thereby make the gas of finally discharging reach the oil smoke discharge standard of stipulating in the GWBP5-2000 discharge standard fully by air outlet.
