Description
Technical field
The present invention relates to a kind of air cleaner, filtering gas and reduce the noise reduction inertial filter of noise by diffraction and sound-absorbing mode behind especially a kind of suction and discharge position that is arranged on building and device.
Background technology
When dust or other impurity enter the inside of machinery or electrical installation, not only indirectly shorten its service life, the variety of issue such as can also directly cause device to shut down or to wreck.Handle assembly is installed to when indoor, can on scavenge port, filter be installed and reduce its injury.But when on scavenge port, filter being installed, following point can appear:
1. because filter filters out polluter with suction type, changed after therefore needing routine observation or visually observe filter.
2. when device or building needed larger ventilation volume, the installation position area of filter was larger, has increased installation difficulty.
3. adsorbed pollutant on filter and when causing filter can't bring into play its performance, will cause overload and make filter impaired device and equipment, even having caused equipment damage.
And if filter or silencing means are not installed, peristome will directly be exposed to the outside.In general, the caused noise of large equipment also needs more air greater than the caused noise of skinny device.Because large noise equipment needs more air, also just need wider peristome, being discharged into outside noise also can be larger, and then forms a vicious circle.
For these problems, the solution that prior art is taked is at the front/rear end face of filter, trumpet type silencer to be installed.
Therefore but the method will increase volume and the weight of filter housing (Casing), even the industry scene need to arrange filter, the also inreal filter of installing is perhaps installed simultaneously adsorption filter and muffler and wasted budget.

The specific embodiment
Describe preferred embodiment of the present invention in detail below with reference to accompanying drawing.
Fig. 1 is noise reduction inertial filter figure of the present invention, and Fig. 2 is the inner section figure of noise reduction inertial filter of the present invention.
As Fig. 1 and shown in Figure 2, noise reduction inertial filter 10 of the present invention comprises: blade (Vane) 100, the dust in filtered air; Dust-exhausting port 200, the dust that above-mentioned blade 100 is filtered is discharged; Air guiding element (Air Guide) 300 can significantly reduce the impedance of the air that flows into above-mentioned blade 100; Shell (Casing) 400, fixing above-mentioned blade 100; Sound-absorbing spare 500 is positioned at above-mentioned shell 400 inside and can prevents noise; And separator (Separator) 600, be positioned at the inside of above-mentioned blade 100, can give play to the effect of bracing frame and separator frame.
Above-mentioned blade 100 comprises: dust guiding element (Dust Guide) 110 directs into above-mentioned dust-exhausting port 200 to airborne dust; And blade fin 120, the cleaned air that filters in above-mentioned dust guiding element 110 is discharged into the outside.
At this moment, more than one at least above-mentioned blade 100 can be installed in above-mentioned shell 400 inside, above-mentioned blade 100 can be played the part of the maincenter role in the dust filter process of dust laden air, can use carbon steel, stainless steel (Stainless steel) and the material of plastic series to make according to type of fluid, be installed after also can changing blade 100 forms according to crushing and degree of filtration.
Above-mentioned dust guiding element 110 comprises counterflow-preventing sill 111 in addition, and these counterflow-preventing sill 111 can prevent that the internal dust adverse current is to outside.
Fig. 3 is the dust filter method figure of Leaf of the present invention.
As shown in Figure 3, the dust filter method (Filtering) of blade 100 of the present invention is as follows.Be separated part (Separator) 600 separation by pressure fan Fan or other dust-laden 20 air of forcing getter device to be sent to.At this moment, larger-size dust is subject to effect of inertia and directly enters dust guiding element (Dust Guide) 110, and the dust 20 that enters above-mentioned dust guiding element 110 inside is blocked by crooked inwardly counterflow-preventing sill 111 and is subject to gravity effect and drops down.
And if flow into blade 100 after the dust of intermediate sizes mixes with cleaned air, blade fin 120 will cause diffraction and above-mentioned dust is dragged for by the paddy 121 between the blade fin, thereby prevent that it from flowing into 120 li of blade fins.At this moment, by the dust that dragged for be subject to dust emissions with pressure fan not shown or flow to dust guiding element 110 certain air quantity impact and finally enter dust guiding element 110.
The dust that converges on dust guiding element 110 is discharged into the outside by dust-exhausting port 200.At this moment, above-mentioned dust-exhausting port 200 can be installed in addition at tail end and eliminate dust pressure fan (Fan, not shown), and above-mentioned pressure fan helps the smooth discharge of dust and improves filter clogging effect.
When having been eliminated the cleaned air after the dust and enter blade fin 120 by above-mentioned dust guiding element 110 and fin collision and carry out diffraction, the air after diffraction is discharged into the floss hole 700 of filter (Filter) after through diffraction again for the first time.Cleaned air after filtration is through flowing into indoor or equipment after such process.
Inertial filter 10 of the present invention has been given up the absorption type filter method and has been adopted the filter method of gravity and inertia, it is the semipermanent filter that to change in addition parts after a kind of the installation, when considering on present industry scene extensively applicable crushing with wind speed, above-mentioned inertial filter 10 can be the filtration of the dust of 10um more than 95%.
Fig. 4 is the noise method for reducing figure of Leaf of the present invention.
As shown in Figure 4, in the present invention, the noise method for reducing of blade and dust filter method Filtering are reverse each other.At first the external noise that flows at floss hole 700 carries out diffraction at the leading section 122 of blade fin, carries out diffraction for the second time through after above-mentioned diffraction for the first time in the rearward end 123 of blade fin, therefore can utilize diffraction to prevent that noise leakage is to the outside.
Except the noise diffraction, the present invention can also utilize inner membrance 410 perforated boards of outer enclosure (Casing) 400 and the sound-absorbing spare 500 of shell 400 inside to give play to the effect that surmounts general trumpet type silencer.
The present invention can be according to air quantity and installation site and at each blade Vane, applicable perforated board separator (Splitter) on 100 and further improve the effect that abates the noise.
Above explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skills understand, in the situation that do not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all will falling into protection scope of the present invention.
