Description
Technical field
The invention belongs to technical field of environment protection equipment, be specifically related to a kind of air-supply arrangement.
Background technology
Penetrate mist dust falling device in the market a lot, but function singleness, common clear water can only be sprayed, and the mist particle diameter ejected is generally hundreds of micron, granularity is big, and it is short that droplet stays aloft the time, the absorption affinity of dust is not strong, especially for the particulate matter less than or equal to 2.5 microns of the diameter in air, its absorption affinity is very weak, makes dedusting air cleaning effect have a greatly reduced quality.Although PM2.5 is component only small in Atmospheric components, but air quality and visibility are had a significant impact by it, compared with thicker Atmospheric particulates, PM2.5 diameter is little, containing a large amount of poisonous and harmful substances, (chemical composition of fine particle mainly includes machine carbon (OC), elemental carbon (EC), nitrate, sulfate, ammonium salt, sodium salt (Na+) etc.), atmospheric residence time is long, distance of floating is remote, health and air quality are affected bigger, so a quality penetrating mist dust falling device, can remove PM2.5 be a critically important index.
Chinese patent CN204494612U discloses a kind of PM2.5 of elimination two-fluid polluted and penetrates mist depositing dust air cleaning facility, and its effect removing PM2.5 is obvious.The performance of air-supply arrangement determines the range penetrating mist dust falling device, and air-supply arrangement is also the maximum noise source penetrating mist dust falling device.
Summary of the invention
For existing air-supply arrangement noise greatly, and performance is difficult to meet the defect remotely penetrating mist dust falling device requirement, and height of the present invention proposes the air-supply arrangement that a kind of performance is high and noise is little.
The technical scheme is that and be achieved in that: a kind of air-supply arrangement, including current collector, impeller and air duct, the first stator, the second stator, impeller cylinder and starting taper it is provided with in described air duct, described impeller cylinder is connected by the first stator and described air duct are fixing, described starting taper is connected by the second stator and described air duct are fixing, described impeller and described impeller cylinder are rotationally connected, and described current collector connects with one end of described air duct, and described air duct inwall is provided with sound absorbing layer.The setting of sound absorbing layer greatly reduces the noise of air-supply arrangement.
More preferably, described air duct is made up of cylindrical section and conical cylinder section, and the tapering of described conical cylinder section is 1:3.3～3.8, and the tapering of described starting taper is 1:1.7～2.2.To reach the effect that windage is little, blast is big, wind speed is fast.
More preferably, with described starting taper in a distance, such structure can produce certain air return to described impeller cylinder, and the motor in impeller cylinder is dispelled the heat.
More preferably, described current collector is provided with end socket and protective cover, and described end socket is positioned at the central authorities of described current collector, it is shown that protective cover is between the shell of described end socket and described current collector.End socket plays guide functions, and protective cover prevents foreign body from entering.
More preferably, the requirement good and fire-retardant for meeting sound-absorbing effect, the material of described sound absorbing layer is that polyurethane sound-absorbing is cotton, and described polyurethane sound-absorbing is made up by cotton of the raw material of following weight portion: polyether polyol 40～50 parts, polypropylene 40～50 parts, vinylacetate 3～5 parts, Graphene 1～2 part, isocyanates 1～2 part, silicon dioxide 2～4 parts, cross-linking agent 1～2 part, chain extender 2～3 parts.
