Description

Cooking fume remover

A kind of cooking fume remover is applicable to the kitchen oil fume purifying of each big hotel, restaurant, catering industry, belongs to special-purpose field, kitchen.

The oil draining system of the kitchen of each big hotel, restaurant and residenter house use now, what all adopt is the lampblack absorber of fan blade type ventilation fan or fan blade type, these ventilations or oil extraction flue gas mode all be directly indoor oil smoke discharge in outside atmosphere since oil smoke in have CO, SO ₂And carcinogenic substance and other pernicious gas air that directly has been discharged in the atmosphere after stain.In fact really do not play the effect that purifies air, and do not meet national pollution emission standard.Existing national regulation, the oil smoke that is not purified does not allow direct discharging.

In view of the deficiency that above-mentioned mist extractor equipment exists, the purpose of this utility model is a kind of novel mist extractor clarifier of design, and this cooking fume remover can make CO, the SO in the oil smoke ₂The greasy dirt of carcinogenic substance and pernicious gas and particulate purifies, and makes the oil smoke after the purification directly discharge atmosphere, meets the index of national requirements for environmental protection fully.

For achieving the above object, the utility model is finished in the following way:

A kind of cooking fume remover is made up of a purifying oil fume cylindrical shell, air intake tube, chimney fan, filler interchanger, grid plate, two-stage spray thrower, filter, feed tube, return pipe.It is characterized in that in the air intake nozzle and in the air-out nozzle blower fan being installed respectively, wherein the air intake tube is installed in the tangential direction in the cooking fume remover cylindrical shell outside, one deck grid plate is installed above in the cylindrical shell of cooking fume remover, active carbon filter is being set above, two row's filler interchangers are equipped with in the middle level, this filler interchanger is to be made of several hollow short tubes, a feed tube is equipped with in the below, two annular liquid pipes direct and that cylindrical shell is interior join, be provided with several shower nozzles on the two-stage annular liquid pipe in cylindrical shell and form spray thrower up and down, the cooking fume remover cylindrical shell is divided into inner and outer wall, the inside and outside wall interlayer has heat-insulation layer, inwall posts Electric radiant Heating Film, under the cooking fume remover cylindrical shell return pipe is housed.

Advantage of the present utility model is: the cooking fume remover reasonable in design, simple, production cost is low, easy to use, its great advantage just is different from the existing lampblack absorber that generally uses, oil smoke can really be purified, oil smoke after the purification also can directly discharge atmosphere, can meet national environmental standard fully.

Further specify in conjunction with the accompanying drawings:

Fig. 1 is that the master of cooking fume remover looks complete section figure.

Cooking fume remover cylindrical shell (1), gas outlet (2), air induction mast, (3), filler interchanger (4), spray head (5), grid plate (6), filter (7), air exhauster (8), air inlet blower fan (9), heat-insulation layer (10), Electric radiant Heating Film (11), feed tube (12), return pipe (13), ring pipe (14).

Oil smoke attracts by the blower fan (9) in the air induction mast (3), enter clarifier cylindrical shell (1) lining along clarifier bottom tangential direction, rotating the liquid mist that produces with one-level spray head (5) at a high speed in the clarifier bottom bumps, at a high speed the air-flow of rotation with big elaioleucite, dust and less material in the oil smoke get rid of to cooking fume remover inner tube wall, less elaioleucite and SO ₂Chemical reaction takes place at air-flow when spraying is cut mutually with liquid in pernicious gases such as carcinogenic substance, and the result of reaction is with SO ₂Become H ₂SO ₄, carcinogenic substance becomes the bottom that water-soluble substances drops to clarifier, to filler interchanger (4), because the exchange area of filler interchanger is bigger, above-mentioned reaction is proceeded, the result's 95% of reaction SO on the oil smoke of unreacted ₂Greasy dirt and pernicious gas are cleaned, under the effect of secondary spray, make harmful substance continue to be dissolved in and be back to the clarifier bottom in the liquid, flow in the fluid reservoir by water return pipeline (13), purified gas is discharged in the atmosphere by gas outlet (2) in the suction of blower fan (8), grid plate (6) places the clarifier middle and upper part, and active carbon filter (7) is being set above it, and the wall of clarifier cylindrical shell (1) is an interlayer, the middle level is insulation material (10), and inwall posts Electric radiant Heating Film (11).Feed pipe (12) one ends and ring pipe (14) join, and the return water tank that the other end and other establish is connected, and discharge opeing return pipe (13) is also received on the return water tank of establishing in addition, and the water reciprocation cycle is used.

Embodiment 1:

Return pipe (13) and the shared water tank of water inlet pipe (12) are established a micropump and are given the cooking fume remover periodical feeding on water tank.
