By using the scheme of the aluminum clapboard cartridge filter, the problem of local impact on and damage to the aluminum clapboard filter caused by powerful turbulence or jittering is solved.
Description
Technical field
The utility model relates to air purification field, is specifically related to a kind of aluminium dividing plate box type filter with current equalizing structure.
Background technology
Because the cleanliness factor of the ventilation shaft such as gas turbine has higher requirement, and itself is because the flow-disturbing problem that system produces when starting needs to use the aluminium baffle filter that can resist strong flow-disturbing.Aluminium dividing plate box type filter commonly used as shown in Figure 1 at present, its structure mainly is comprised of filter core 1 and outside framework, wherein filter core 1 becomes pulse form to consist of by resistant to elevated temperatures middle effect glass folded filter paper, in order to increase the intensity of filter core 1, keep uniform pleat space, airflow smooth is passed through, between the filter paper pleat, fold up the aluminium dividing plate.Then install protection network additional in filter core 1 both sides; protection filter core 1 is not touched or clashes into causes breakage; this kind filter can reach filter effect preferably in the uniform ventilation shaft of air-flow; but; in the air channel that powerful flow-disturbing or shake are arranged, bump both sides filter paper after the aluminium dividing plate is impacted by flow-disturbing, and the edge of aluminium dividing plate is sharper; filter paper is subjected to repeatedly to clash into easy breakage, causes leaking.So how developing a kind of aluminium dividing plate box type filter that can bear powerful flow-disturbing impact becomes research topic of the present utility model.
Summary of the invention
The utility model provides a kind of aluminium dividing plate box type filter with current equalizing structure, its objective is will solve powerful flow-disturbing or shake the problem that causes local assault to damage to the aluminium baffle filter.
For achieving the above object, the technical solution adopted in the utility model is: a kind of aluminium dividing plate box type filter with current equalizing structure, comprise filter core, outside framework and the first protection network, outside framework consists of rectangular frame by the high-order frame of grooved and the wide position of grooved frame, filter core is installed in this rectangular frame, one end of rectangular frame is as the airflow inlet end, the other end is as airflow outlet end, the first protection network is positioned at airflow outlet end, and rectangular frame is fixed relatively, it is characterized in that: be provided with a homogenizing plate at the airflow inlet end, offer equal discharge orifice on this homogenizing plate, described equal discharge orifice evenly distributes on homogenizing plate.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described equal discharge orifice is the circular hole of diameter in 6.0 ~ 8.0 millimeters scopes, and the percent opening of the circular hole of described homogenizing plate is between 50% ~ 70%, and percent opening refers to the gross area of equal discharge orifice on the homogenizing plate and the ratio of the whole homogenizing plate gross area.
2, in the such scheme, described " high-order direction " refers to that filter core is folded to direction, and described " high-order frame " refers to the set frame in two ends that is folded to direction along filter core; " wide position frame " refers to along the set frame in two ends that can count filter core folding line number.
The utility model operation principle is: the airflow inlet end at rectangular frame is provided with a homogenizing plate, airflow outlet end is provided with the first protection network, offer equal discharge orifice on the homogenizing plate, all discharge orifice evenly distributes on homogenizing plate, homogenizing plate plays current balance function when impacted by strong flow-disturbing to filter core, so that the filter durable.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, because the utility model adopts homogenizing plate, so that filter is made time spent diffusing air current equably being subject to strong flow-disturbing, guarantee that the blast at each position of aluminium dividing plate is roughly the same, make the aluminium dividing plate in this air channel with strong flow-disturbing and shake, not damage filter core.
2, because the utility model employing percent opening is 50% ~ 70% homogenizing plate, can not increase structural drag to filter, guarantee simultaneously the draught area that filter is enough.
3, because the homogenizing plate that the utility model adopts is simple in structure, be convenient to produce.
