Abstract
The utility model discloses an oil and smoke exhausting apparatus integrating oil removing and noise abatement, and is characterized in that the utility model consists of a front part and a rear part which are connected together, wherein the front part is the oil removing part adopting the way of filtering and the rear part is the noise abatement part adopting the double-layer micropunch plate. The utility model integrates oil removing with noise abatement, and solves a series of environmental problems caused by oil and smoke exhaustion in restaurants. As for oil removing, the way of filtering is adopted, which overcomes such traditional disadvantages as large resistance of filtering method, weak oil holding capability and inconvenient replacement of filtering materials, compared to traditional filtering method. However, the utility model takes these factors into full consideration on the selection and the arrangement of filtering materials as well as the structure of the oil and smoke exhauster, thereby reducing resistance, increasing oil holding capability and making the replacement of filtering materials convenient. Meanwhile, as the noise produced by the air flow is considered, a noise abatement sheet is arranged in the oil and smoke exhauster.
Description
Technical field
The utility model relates to a kind of flue gas removing device that oil removing and noise reduction are integrated that collects.
Background technology
2000, State Environmental Protection Administration issued " cooking fume discharge standard ", and cooking fume control equipment must be installed by the industry of putting somebody on a diet unit, belonged to without any oil smoke discharge that removes the purification of oil smoke cleaning equipment to exceed standard.So, various forms of fume purifier of fume have appearred in recent years, electrostatic method is arranged, and wet method and filtration method etc. are though these methods have all been ignored the noise generated by air flow problem in its advantage separately aspect oil smoke.Because any remove precipitators when operation always with air motion, need be furnished with blower fan.Though tradition is removed the noise that the oil smoke system has considered blower fan itself, does not consider for noise generated by air flow.After having caused the part restaurant that fume purifier of fume has been installed, former quiet environment is brought noise, influence resident's normal life.In addition, existing all kinds of flue gas removing device has all been run into the problem of cleaning difficulty.
Summary of the invention
Technical problem to be solved in the utility model is, makes except that precipitators to reduce noise when can better removing oil smoke, and for this reason, the utility model provides a kind of flue gas removing device that oil removing and noise reduction are integrated that collects.
The technical solution adopted in the utility model is: a kind ofly collect the flue gas removing device that oil removing and noise reduction are integrated, be characterized in being formed by connecting for two sections by front and back, leading portion adopts the oil removing section of filtration method, and back segment adopts the noise reduction section of the anechoic sheet of double-deck microperforated panel.
Described a kind of flue gas removing device shell that oil removing and noise reduction are integrated that collects: main body adopts rectangle, two connects reducing pipe, two fan doors are housed in the front of equipment, one side of door hinges, be located between two sections of the silencing range hood devices, another side adopts the refrigerator knocker, makes things convenient for the cleaning of filtrate and anechoic sheet.
Described leading portion: adopt the filtration method oil removing, adopt the scouring pad filtrate, clamp with zinc-coated wire on the two sides, encase with iron sheet all around, be fixed on the support, make the as a whole pull that carries out, make things convenient for the cleaning of oil cleaner screen, make at filtrate in the arrangement of oil cleaner screen, adopt one to three group Aug. 1st shape to arrange, perpendicular to the horizontal plane of housing, the splayed oil cleaner screen becomes 60-80 degree angle with the horizontal crest line of housing, the in-line oil cleaner screen is then perpendicular to the horizontal crest line of housing, and splayed oil cleaner screen and in-line oil cleaner screen are spaced.
Described back segment is provided with the multi-disc anechoic sheet, is evenly distributed in the housing, and anechoic sheet is made up of inside and outside two layers of porous plates, and anechoic sheet is fixed on the support, makes the as a whole pull that carries out, and makes things convenient for the cleaning of silencing apparatus.
The beneficial effects of the utility model are: the utility model is that collection oil removing and noise reduction are integrated, thoroughly solve restaurant's mist extractor with a series of environmental problems.Aspect oil removing, adopt filtration method, to compare with traditional filtration method, its principle is similar, it is simple to have continued its technology, rational in infrastructure, the advantage of equipment installation and convenient operating maintenance.But traditional filtration method resistance is big, ability of retaining oil is not strong, filtrate is changed trouble, and the utility model is in the selection of filtrate, on the layout of filtrate, these factors have all been considered on the structure of precipitators, reduce resistance, strengthened ability of retaining oil, made things convenient for the replacing of filtrate.Simultaneously, also consider noise generated by air flow, in precipitators, adorned anechoic sheet.
