Oil fume purification device of oil fume exhauster
Technical field
The present invention relates to purifier, be specifically related to a kind of oil fume purification device of oil fume exhauster.
Background technology
Smoke exhaust ventilator claims range hood again, is a kind of household electrical appliance that purify kitchen environment, the part oil smoke and the water vapour that produce in the refuse of cooking stove burning and the cooking process can be taken away, discharges outdoorly, reduces and pollutes, the purification air in kitchen; And smoke exhaust ventilator is discharged in the outdoor air-flow, still contain a certain amount of oil smoke and water vapour, these oil smoke and water vapour severe contamination outdoor environment, particularly catering trade uses large-scale smoke exhaust ventilator to discharge in the outdoor air-flow, contain a large amount of oil smoke and water vapour, directly be discharged into mostly in the air, the oil smoke smog of discharging has seriously influenced air quality, cause near the trees flowers and plants of smoke exhaust ventilator exhaust outlet to be infected with sump oil, then constantly take place dead.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, a kind of oil fume purification device of oil fume exhauster is provided.
Oil fume purification device of oil fume exhauster is made up of casing, upper cover plate, air inlet pipe, clean room, blast pipe, sewage pipe and blowdown oil pipe.
The present invention is achieved by following technical proposals:
Oil fume purification device of oil fume exhauster is a rectangular combined labyrinth and carbon gland casing, air inlet pipe is fit in the 1st clean room from upper cover plate, the end opening of air inlet pipe is the loudspeaker tubular, help oil smoke air-flow large-area discharging in the 1st clean room of smoke exhaust ventilator, the end opening of air inlet pipe is equal with the sump oil upper horizontal plane in the 1st clean room, because gravity effect and outside air temperature are lower than the temperature in the smoke exhaust ventilator, most of oil smoke cyclostrophic of smoke exhaust ventilator discharging turns to greasy dirt and sewage falls into bottom, the 1st clean room;
A steam vent is opened in the upper end of dividing plate between the 1st clean room and the 2nd clean room, and part oil-containing flue gas stream enters in the 2nd clean room from the 1st clean room; An outage is opened in the bottom of steam vent, the top of outage is equal with the sump oil upper horizontal plane in the 1st clean room, the bottom of outage is equal with the sewage upper horizontal plane in the 1st clean room, and when the sump oil in the 1st clean room was higher than the sump oil upper horizontal plane, sump oil flowed in the 2nd clean room; An osculum is opened in the dividing plate lower end, and the 1st clean room is communicated with the 2nd clean room, and the sewage of the 1st clean room and the 2nd clean room is discharged from the sewage pipe of the 1st clean room;
An exhaust outage is opened in the upper end of dividing plate between the 2nd clean room and the 3rd clean room, the air-flow that contains oil smoke enters the process of the 2nd clean room from the 1st clean room, sump oil and sewage in the oil-containing flue gas stream fall into bottom, the 2nd clean room, at this moment air draught has obtained preliminary purification, air-flow enters in the 3rd clean room after the preliminary purification, and the sump oil of the 2nd clean room also enters in the 3rd clean room from the exhaust outage; Blast pipe is fit in the 3rd clean room from upper cover plate, the end opening of blast pipe is the loudspeaker tubular, the oil smoke air-flow has obtained further purification in the 3rd clean room, the sump oil and the sewage of trace fall into bottom, the 3rd clean room, and the air-flow after the purification is discharged from blast pipe at last;
An outage is opened in the upper end of dividing plate between the 3rd clean room and the 4th clean room, the sump oil that is used in the 3rd clean room flows in the 4th clean room, an osculum is opened in the lower end of dividing plate between the 3rd clean room and the 4th clean room, the 3rd clean room is communicated with the 4th clean room, and the sewage that helps the 3rd clean room and the 4th clean room is discharged from sewage pipe; Sump oil and sewage in the 4th clean room because the effect of gravity, sump oil all swims on the sump oil upper horizontal plane, and sump oil is discharged from oil exit pipe, and settlement of sewage is below the sump oil upper horizontal plane, sewage is discharged from sewage pipe, opens the upper cover plate of casing and can unpick and wash each clean room.
Because gravity effect and outside air temperature are lower than the temperature in the smoke exhaust ventilator, the oil smoke cyclostrophic of smoke exhaust ventilator discharging turns to greasy dirt and sewage falls into respectively in four clean rooms, and smoke exhaust ventilator discharging oil smoke air-flow is discharged from blast pipe through purifying the back.
The oil fume purification device of oil fume exhauster process for purifying is simple, and water-oil separating is remarkable, good purification; Sump oil and sewage can be collected respectively, and hygienic environment-protecting does not pollute.
Oil fume purification device of oil fume exhauster need not additionaling power, and operating cost is cheap, unpicks and washes conveniently.
Oil fume purification device of oil fume exhauster is applicable to the oil smoke gas that purifies smoke exhaust ventilator.
