Abstract
The invention discloses a silencing machine for removal of oil fume, characterized in that it is formed by front and back segments, the front segment is the segment for removal of oil by filtering method and the back segment is the silencing segment by silencing plate, which is double-layer plate with micro-hole. In the invention removal of oil and silencing are combined together and a series of environmental problems generated by exhaust oil fume in restaurant are solved. In removal of oil, the filtering method conquers disadvantages of conventional filtering method, such as big resistance, bad ability for retaining oil and troubled exchanging filter material, compared with the conventional filtering method. in the invention on the selection of filter material, assignment of filter material, the structure of oil fume machine these factors are considered. It decreases the resistance, strengthens the ability retaining oil and exchange the filter material in convenience. Meanwhile, the noise generated by air flow is considered and silencing plate is installed in the oil fume machine.
Description
Technical field
The present invention 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 by this invention is, makes except that precipitators to reduce noise when can better removing oil smoke, for this reason, the invention provides the silencing range device.
The technical solution used in the present invention is: a kind of silencing range hood device, be characterized in being formed by connecting for two sections by front and back, and 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 silencing range hood device shell: main body adopts rectangle, and two connects reducing pipe, and two fan doors are housed in the front of equipment, one side the hinging of door is 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 invention has the beneficial effects as follows: the present invention 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 present invention 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.

The specific embodiment
A kind of silencing range hood device by shown in Figure 1, is characterized in being formed by connecting for two sections by front and back, and leading portion 1 adopts the oil removing section of filtration method, and back segment 2 adopts the noise reduction section of the anechoic sheet of double-deck microperforated panel.
By shown in Figure 1, described silencing range hood device shell: main body adopts rectangle, two connects reducing pipe, in the front of silencing range hood device two fan doors are housed, a fan is muffler section door 3, and another fan is the door 5 of oil removing section, one side of door hinges 4, be located between two sections of the silencing range hood devices, another side adopts refrigerator knocker 6, makes things convenient for the cleaning of filtrate and anechoic sheet.Door is consistent with the material of shell, desirable stainless steel and galvanized sheet, thickness 1.2-2mm.
By shown in Figure 2, described leading portion 1: adopt the filtration method oil removing, adopt 5-10mm 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, by shown in Figure 3, 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, splayed oil cleaner screen 9 becomes 60-80 degree angle with the horizontal crest line of housing, 8 of in-line oil cleaner screens are perpendicular to the horizontal crest line of housing, and splayed oil cleaner screen and in-line filtrate net are spaced.Like this, can increase oil suction face, also increase gas channel, reduce the resistance of fluid.
By shown in Figure 2, described back segment 2 is provided with the multi-disc anechoic sheet, is evenly distributed in the housing, anechoic sheet is made up of inside and outside two layers of porous plates, by shown in Figure 4, and internal layer 10 percent opening 1%-1.5%, outer 11 percent opening 2%-3%, ectonexine is 30-50mm at interval, and cavity 12 is 100-150mm.Present embodiment, anechoic sheet have been established six altogether, are evenly distributed in the housing, and middle four are divided into two groups, and available semicircle dull and stereotyped a connection of every group, the other end connects with dull and stereotyped.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 anechoic sheet material can adopt thick aluminium sheet of 0.6-1.0mm or corrosion resistant plate.
