Abstract
The utility model relates to a high-efficiency gas filter which is a filtering device used for preventing toxic gas and smog and protecting environment. The utility model is characterized in that a plurality of hole plates with equal or unequal number of holes are orderly arranged in the filter, filtering materials are clamped between the hole plates, the arranging order of the hole plates is that the hole number on the back row of hole plates is more than or equal to the hole number on the front row of the hole plates, and therefore, the flow quantity, the flow speed, the flowing state and the adsorption rate of gas passing through the filter are changed. The filtering materials are clamped by the multi-layer hole plates so that the adsorption rate of the utility model is largely raised, and the content of harmful substance in the gas is reduced after the gas is filtered so that the utility model has high filtering effect.
Description
The utility model relates to a kind of High-Performance Gas Filter, and it is the filter that is used for gas roof, smog and environmental protection aspect.
Existing pneumatic filter is to adopt homogeneous, the filter media material of equal density, and permanent filtering traffic, the permanent flowing gas state that filters, the permanent adsorption rate of filtering, its filter effect is not good, and the harmful substance in the gas can not reduce significantly.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple in structure, the High-Performance Gas Filter that flow, flow velocity and flow regime are changed.
The technical solution of the utility model: High-Performance Gas Filter is to comprise shell and filtering material, it is characterized in that the shell entrance point is provided with a plurality of orifice plates successively, is provided with filtering material between its orifice plate and the orifice plate; Set gradually and have all on the orifice plate in the enclosure that quantity equates or unequal passage, orifice plate erection sequence successively is a hole count on the hole count 〉=front-seat orifice plate of back round plate.Change thereby make by the flow in the filter, flow velocity, flow regime and filter medium adsorption rate etc., when the filter medium sectional area reduces, flow velocity increases, its adsorption rate height; Can reduce the harmful substance in the gas significantly, thereby improve filter efficiency.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2, Fig. 3 are the orifice plate schematic diagram of the different hole counts among the embodiment with Fig. 4.
Referring to Fig. 1, High-Performance Gas Filter is made up of shell 1, orifice plate 2 and filtering material 3, and entrance point sets gradually a plurality of orifice plates 2 in shell 1, between orifice plate 2 and the orifice plate 2 filtering material 3 is set, and the rear end of shell 1 also is provided with filtering material 3.All having quantity on a plurality of orifice plates 2 equates or unequal passage.Hole count on hole count 〉=front-seat orifice plate 2 after orifice plate 2 is arranged in order and is in proper order on the round plate 2.Be that the less orifice plate of hole count (as shown in Figure 2) is arranged on front end, the more orifice plate (as shown in Figure 3) of hole count is arranged on thereafter, the orifice plate that hole count is maximum (as shown in Figure 4) is arranged at last, when practical application, also can be arranged in the filter with the orifice plate of a plurality of identical hole counts.The aperture of the passage on the orifice plate 2 can require design according to reality
In sum, the utility model is simple in structure, cost is low, easy to use, good filtration effect, the multi-level orifice plate of employing insert and put filter media material, its adsorption rate increases substantially, and the content of harmful and noxious substance reduces significantly in the gas after the filtration, thereby has improved filter efficiency.
