Detailed description of the invention
Below, with reference to accompanying drawing, the utility model filter is preferred embodiment described.Fig. 1 is the schematic diagram of the structure representing the dust-precipitating system 100 possessing the utility model filter 10 preferred embodiment.
As shown in Figure 1, the dust-precipitating system 100 of the filter 10 of present embodiment is used to possess dust shield 102, dust arrester 104, filter 10 and air blast 106.Self-priming dust hood 102 sucks the air being attended by dust, and this air is sent into dust arrester 104.Implement solid and gas in the inside of dust arrester 104 to the air sucked to be separated, thus remove most dust (dedusting).Afterwards, the waste gas comprising a little dust be not removed is inhaled into filter 10 from the exhaust outlet 104a of dust arrester 104 via pipeline 108.
The waste gas being inhaled into filter 10 implements solid and gas separation further in filter 10, is disposed to outside at filter 10 by the waste gas (clean air) after further dedusting via air blast 106 and discharge duct 110.
Then, with reference to Fig. 2 to Fig. 5, the filter 10 of the preferred mode of the utility model is described.Fig. 2 is the side view of the utility model filter 10 preferred embodiment, and Fig. 3 is the top view of filter 10.In addition, Fig. 4 is the sectional view of the A-A line along Fig. 2.
The main body 12 that filter 10 possesses the box of the roughly rectangular shape with inner space and the filter element 16 be configured in inner space 14.The size shape in the outside of filter element 16 and the Xray films shape of inner space 14 roughly equal, to be configured in inner space 14 extend along the vertical direction and space, the downstream 14b of inner space 14 is divided into two the upstream side space 14a that becomes inflow side and discharge side.
Be provided with the open-topped waste gas suction inlet 18 at upstream side space 14a at the roof of main body 12, the exhaust of dust arrester 104 can be imported upstream side space 14a from top.Be formed with the exhaust outlet 20 to space, downstream 14b opening at the rear wall of main body 12, thus the gas in the 14b of space, downstream can be discharged.
In addition, be provided with at the antetheca of main body 12 the upstream side inspection door 22 communicated with upstream side space 14a in opening and closing mode freely, be provided with at the sidewall of main body 12 the downstream inspection door 24 communicated with space, downstream 14b in opening and closing mode freely.By opening this door 22, upstream side space 14a can being entered, by opening this door 24, space, downstream 14b can be entered.
Further, in order to grasp filter degree of fouling, the pressure gauge 26 for measuring the pressure differential before and after filter is installed on the main body 12.
Filter element 16 is can the filter component of dedusting efficiently, and it possesses: cancellate flase floor 28; Filter installing frame 30, it can be installed on opening portion (grid) 28a of flase floor 28 and can pull down from the opening portion of flase floor 28 (grid) 28a; And filter element 32, it is installed on filter installing frame 30.
Flase floor 28 is the components formed by steel plate is processed into clathrate, and has the opening portion 28a of the multiple rectangles arranged regularly.In addition, the contour shape of the longitudinal section of the size shape in the outside of flase floor 28 and the inner space 14 of main body 12 is roughly equal.
Further, flase floor 28 is configured to extend along the vertical direction in the substantial middle position of the fore-and-aft direction (left and right directions of Fig. 3) of inner space 14 and space, the downstream 14b of be divided into two inner space 14 the upstream side space 14a that becomes inflow side and discharge side.Each outer surface of flase floor 28 is connected to the inner surface of main body 12, and utilization is fixedly welded on main body 12.
Filter installing frame 30 is cross sections is roughly foursquare cylindrical body (Fig. 5), and this cylindrical body has the size shape of the spatial portion (grid) that seamlessly can embed flase floor 28.
Filter element 32 is that Medium performance filter or high-performance filter etc. can the filter elements of dedusting efficiently.In this manual, Medium performance filter refers to the filter of collection efficiency more than 95% recorded by colorimetric method, and high-performance filter refers to HEPA filter or ulpa filter.
HEPA filter is the filter being defined as " collection efficiency with the particle of 0.3 μm under nominal air delivery is more than 99.97% and initial pressure loses the air cleaner of the performance for below 245Pa " by Japanese Industrial Standards JIS Z8122.
In addition, ulpa filter is the filter being defined as " have the particle being 0.15 μm to particle diameter under nominal air delivery have the powder collection rate of more than 99.9995% and initial pressure loses the air cleaner of performance for below 245Pa " by identical Japanese Industrial Standards JIS Z8122.
When filter element 32 is installed on filter 10, utilizes screw to be fixed on by filter installing frame 30 in spatial portion (grid) 28a of flase floor 28, then, filter element 32 is inserted (Fig. 5) in filter installing frame 30.
Not shown sealing gasket is embedded with at filter installing frame 30, be close to by sealing gasket and filter element 32 and keep sealing, further, filter element 32 is installed on the spring clip (not shown) of filter installing frame 30 by the method utilization of prior art and is fixed in filter installing frame 30.
In the filter 10 of the present embodiment so formed, the waste gas carried out after solid and gas is separated at dust arrester 104 imports filter 10 via pipeline 108 from the waste gas suction inlet 18 of main body 12.The waste gas importing waste gas suction inlet 18 is directed to the upstream side space 14a of filter 10, implements after solid and gas is separated, to flow into space, downstream 14b utilizing the filter element 32 of filter element 16.Then, the waste gas flowing into space, downstream 14b is discharged from filter 10 through exhaust outlet 20, and, the outside of dust-precipitating system 100 is discharged into via air blast 106 and discharge duct 110.
By arranging the filter of present embodiment, there is following effect: exhaust concentration can be reduced to 0.005g/m
3about N, thus the air that more clean conditions can be discharged.
The utility model is not limited to described embodiment, can carry out various change, distortion in the scope of the technological thought described in claims.
