The utility model is characterized in that a purification room is arranged in the exhaust cylinder; the air inlet side of the purification room and the air outlet side of the purification room are provided with filter screens; a circulating liquid-spraying system is arranged in the purification room, and the circulating liquid-spraying system is composed of a dirty liquid tank, a liquid inlet pipe, a liquid pump, a liquid outlet pipe, two circular branch pipes, two liquid-spraying pipes and three spray heads. The utility model has the advantages of simple structure, low cost and less power consumption; owing to the washing action of the circulating liquid-spraying system in the exhaust cylinder to the fume, the utility model also has the advantages that the effect of fume exhausting is good, the fume removing rate can reach 90% to 95%, and the environment can not be polluted.

Description

A kind of environmental purification range hood

The utility model relates to the kitchen utensils in hotel, hotel, promptly a kind of environmental purification range hood.

Some big smoke exhaust ventilators are installed in hotel, wineshop in the workplace of kitchen at present, the oil smoke of having got rid of the kitchen by chimney stack, though improved the condition of work in kitchen, but a large amount of pernicious gas in the oil smoke directly is emitted in the atmosphere, had a strong impact on the air and the environmental sanitation in city, traditional smoke exhaust ventilator can not be eliminated toxic gas contained in the oil smoke.

The purpose of this utility model is to provide a kind of range hood that can separate, purify oil smoke, and the gas of the cleaning after the purification is drained in the atmosphere.

The purpose of this utility model is to realize like this, this environmental purification range hood, by the oil-collecting petticoat pipe, filter grid, oil collection box, blower fan and aiutage are formed, the oil-collecting petticoat pipe is installed in the top of pot, filter grid tilts to be installed in the oil-collecting petticoat pipe, oil collection box is installed in the below of filter grid, the aiutage of erectting is installed in outdoor, in the wall hole between oil-collecting petticoat pipe and the aiutage blower fan is installed, be characterized in aiutage, being provided with the clean room, inlet side and air side in the clean room are provided with screen pack, be mounted with a circulation spray system in the clean room, soiling solution tank is below aiutage, feed tube one end is connecting liquid pump, the other end inserts in the soiling solution tank, drain pipe one end connects liquid pump, the other end stretches into the center, clean room, the fluid pipe end is divided into straight up and consistent with the horizontal fan axis two arms, arm links to each other with two annular sparge pipes, spacing 0.5～3cm is arranged on the sparge pipe, many apertures of φ 1～5mm, sparge pipe is installed in the inboard of screen pack, parallel with screen pack, at a distance of 0.5～1cm, on the horizontal plane of the horizontal branch pipe of clean room, 3 horizontal shower nozzles also are installed, and these 3 horizontal shower nozzles and horizontal branch pipe are formed cross, and the base plate of clean room is the recessed arc that makes progress, the oil leaking hole that a plurality of 15～25mm are arranged on the arc, the arc bottom is a funnel, and the funnel bottom is an oil exit pipe, and the lower end of oil exit pipe is stretched in the soiling solution tank.

Also can settle a joint spiral guide sheet in the aiutage on top of side is given vent to anger by the clean room, the outer and the aiutage of spiral guide sheet weld together.

Also bad-smell adsorber can be installed on give vent to anger the exhaust barrel on top of side in the clean room, bad-smell adsorber is the box that many apertures are arranged on the box wall, and active carbon is housed in the box.

The utility model has the advantages that: simple in structure, make easily, cost is low, power consumption is little, the de-oiling cigarette is effective, because the effect of the circulation spray system in the aiutage, the rate of deoiling in the flue gas reaches 90～95%, goes the flavor rate can reach about 90%, makes atmosphere not contaminated.
