Abstract

The invention discloses a kitchen oil smoke purifier which comprises a smoke collecting hood and a flue; a blower is provided at the outlet end of the flue; the top of the smoke collecting hood is sheathed in the front end of the flue to lead the external lateral wall of the top of the smoke collecting hood and the internal lateral wall of the front end of the flue to form a grease collecting tank; on top of the smoke collecting hood, a gas-liquid separation cap with a hole is provided; the upper end of the gas-liquid separation cap with the hole in the flue is provided with a packing layer; on the wall of the flue of the grease collecting tank, a grease outlet is provided and is connected with a grease separation tank; the upper end of the grease separation tank is communicated with the grease collecting tank while the lower end is communicated with a circulating water flume, the top of which is connected with a water replenishing pipe; an water inlet is arranged on the wall of the flue of the upper end of the packing layer; the water inlet pipe of a circulating pump is connected with the circulating water flume while the water outlet pipe of the circulating pump is connected with the water inlet. The kitchen oil smoke purifier of the invention has the beneficial effects as follows: after purification treatment is carried out to the oil smoke, the purifying rate of the oil smoke is above 95 percent and can reach the A-class standard of national standard, thus the oil smoke discharged outside is relatively clean air.

Description

Kitchen oil fume purifier

Technical field

The present invention relates to a kind of fume purifier of fume.

Background technology

Family kitchen and catering trade and other food processing industrys also can produce harmful materials such as a large amount of oil smoke and carbon monoxide, sulfur dioxide, hydrocarbon in gastronomical process.Wherein 3, the 4-BaP is strong carcinogenic substance.The smoke exhaust ventilator that existing market is sold all has only the Oil-gas Separation function, and clearance is lower, most of smoke exhaust ventilator and ventilating fan just directly enter atmosphere to oil smoke and the pernicious gas that setting produces, though made the air cleaner in the kitchen, but this is pollution transportation, still can pollute atmospheric environment, and family kitchen enormous amount, the oil smoke total amount of its discharge is considerably beyond the total amount of catering trade and other food processing industrys, and family's fume pollution is very important to the pollution that atmospheric environment causes.

Summary of the invention

The purpose of this invention is to provide a kind of can be to the fume purifier of fume of oil smoke oil removing and flue dust.

The objective of the invention is to realize in the following way: a kind of kitchen oil fume purifier, comprise exhaust fume collecting hood, flue, at the flue outlet end blower fan is arranged, the petticoat pipe top is enclosed within the flue front end, make petticoat pipe top lateral wall and flue front end madial wall form the profit collecting tank, on the top of petticoat pipe gas-liquid isolating cap with holes is arranged, packing layer is equipped with in the upper end of gas-liquid isolating cap with holes in flue; Have the profit outlet on the walling of flue of profit collecting tank, the profit outlet connects oil-water separation tank, the upper end connected set oil groove of oil-water separation tank, and the lower end communication loop tank of oil-water separation tank connects filling pipe on the circulating water chennel; On the walling of flue of packing layer upper end, water inlet is arranged; The water inlet pipe of circulating pump connects circulating water chennel, and outlet pipe taps into the mouth of a river.

In flue, the secondary petticoat pipe is equipped with in the upper end of packing layer, secondary petticoat pipe and flue madial wall form the flue dust collecting tank, secondary gas-liquid isolating cap with holes is arranged on the top of secondary petticoat pipe, the secondary packing layer is equipped with in the upper end of secondary gas-liquid isolating cap with holes in flue, on the walling of flue of flue dust collecting tank, have the flue dust water out, on the walling of flue of secondary packing layer upper end, the secondary water inlet is arranged; Circulating pump is a multistage pump, and the water inlet pipe of circulating pump connects the flue dust water out, and outlet pipe connects the secondary water inlet, connects the fluid infusion groove on the outlet pipe of circulating pump.

The present invention has following beneficial effect, by purified treatment to oil smoke, the purifying rate of oil smoke is reached more than 95%, meet " cooking fume purifier " fully (HCRJ048-1999) and " specification requirement of cooking fume cleaning equipment and the inspection specifications " technical conditions and requirement of (HJ/T62-2001) stipulating, can reach the category-A standard of national regulation.Therefore being discharged into outdoor is the suitable air of cleaning.
