Abstract
The utility model relates to a kind of heat recovery boiler dust removal filter web plate, comprises web plate housing, the web plate body be arranged in web plate housing, and web plate body evenly offers elongate holes.After three road slag bath screen packs, remaining cinder mostly is irregular graininess, aperture on easy blocking web plate, after the utility model changes the perforate on heat recovery boiler dust removal filter web plate into elongate holes, clogging can effectively be alleviated, water in dust removal can be made again in addition to increase water yield, extend maintenance period.
Description
Technical field
The utility model relates to a kind of filter, especially relates to a kind of heat recovery boiler dust removal filter web plate.
Background technology
At present, the boiler room heat recovery boiler dust removal filter web plate of automobile production producer is arranged by uniform aperture, and after using one to two moon, the aperture clogs on web plate is serious, and need again to clear up, life cycle is shorter.
Chinese patent CN203281555U discloses dust-removal cloth-bag, filter screen, leaf filter cleaning machine, comprise support body, support body is provided with one or be set side by side with at least two are inserted cleaning along the longitudinal direction flushing channel for be cleaned, two sidewalls of flushing channel are relatively set with two groups of shower nozzles, two groups of shower nozzles comprise respectively multiple spaced, for treating the both side surface water spray of cleaning part or jet shower nozzle, each shower nozzle all be arranged on support body, for the medium transport pipeline connection of water delivery or gas.Although this utility model to board-like filter screen, filter bag cleaning, still can not solve the problem of web plate surface blocking.
Utility model content
The purpose of this utility model is exactly provide one to make water in dust removal increase water yield to overcome defect that above-mentioned prior art exists, extends the heat recovery boiler dust removal filter web plate of maintenance period.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of heat recovery boiler dust removal filter web plate, comprises web plate housing, the web plate body be arranged in web plate housing, and described web plate body evenly offers elongate holes.
Preferably, elongate holes is embarked on journey shape distribution, the elongate holes position consistency between adjacent rows or interlaced.
Preferably, the length of elongate holes be often go adjacent two elongate holes spacing 2-3 doubly, width is often go the 1/3-1/2 of spacing of adjacent two elongate holes.
Preferably, the medial surface of elongate holes is ramp structure, and from the front of web plate body, rearwardly the cross-sectional area of elongate holes reduces gradually.
More preferably, the medial surface of elongate holes and the angle of horizontal direction are 30 °-45 °.
Compared with prior art, the utility model has the following advantages:
(1) after three road slag bath screen packs, remaining cinder mostly is irregular graininess, aperture on easy blocking web plate, after changing the perforate on heat recovery boiler dust removal filter web plate into elongate holes, clogging can effectively be alleviated, water in dust removal can be made again in addition to increase water yield, extend maintenance period;
(2) by controlling spacing between the concrete size of elongate holes and adjacent holes and position, boiler steam etc. is facilitated to pass through;
(3) pass through the structure inside setting elongate holes, facilitate Boiler Cinder Surveying, cinder is not easily assembled in elongate holes and causes blocking mesh, thus reduce human cost, raising water yield, extend maintenance period.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model in embodiment 1.
In figure, 1-elongate holes, 2-web plate body, 3-web plate housing.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment 1
A kind of heat recovery boiler dust removal filter web plate, its structure as shown in Figure 1, comprises web plate housing 3, the web plate body 2 be arranged in web plate housing 3, and web plate body 2 evenly offers elongate holes 1.Elongate holes 1 embark on journey shape distribution, elongate holes 1 position consistency between adjacent rows.In the present embodiment, the length of elongate holes 1 is often go 3 times of spacing of adjacent two elongate holes 1, width be often go adjacent two elongate holes spacing 1/3.The medial surface of elongate holes 1 is ramp structure, and the angle of medial surface and horizontal direction is 30 °, and from the front of web plate body, rearwardly the cross-sectional area of elongate holes reduces gradually.
Embodiment 2
A kind of heat recovery boiler dust removal filter web plate, comprises web plate housing, the web plate body be arranged in web plate housing, and web plate body evenly offers elongate holes.Elongate holes embark on journey shape distribution, the elongate holes position between adjacent rows is interlaced.The length of elongate holes is often go 2 times of spacing of adjacent two elongate holes, width be often go adjacent two elongate holes spacing 1/2.The medial surface of elongate holes is ramp structure, and the angle of medial surface and horizontal direction is 45 °, and from the front of web plate body, rearwardly the cross-sectional area of elongate holes reduces gradually.
After three road slag bath screen packs, remaining cinder mostly is irregular graininess, aperture on easy blocking web plate, after the utility model changes the perforate on heat recovery boiler dust removal filter web plate into elongate holes, clogging can effectively be alleviated, by controlling spacing between the concrete size of elongate holes and adjacent holes and position, boiler steam etc. is facilitated to pass through, by the angle of the structure inside setting elongate holes also by experiment and between simulation calculation acquisition medial surface and horizontal direction, thus make cinder not easily in elongate holes assemble cause block mesh, water in dust removal can be made again in addition to increase water yield, extend maintenance period.
Claims (5)
