Abstract
The invention discloses a fuel-air separator filter core of an oil-spraying rotary air compressor. The fuel-air separator filter core of the oil-spraying rotary air compressor comprises supporting networks and a separation layer, and is characterized in that the separation layer comprises a foldable separation layer (2), a flat seizing type separation layer (4) and an aggregation layer (7), wherein the foldable separation layer (2) is the outmost layer, the flat seizing type separation layer(4) is the middle layer, and the aggregation layer (7) is the innermost layer; the foldable separation layer (2) is formed by utilizing multi-layer submicron glass fiber filter paper to wrap a metallic mesh grid and pressing into a drape-like shape, and is arranged between the supporting network (1) and the supporting network (3); the flat seizing type separation layer is formed by winding the multi-layer submicron glass fiber filter paper on the metallic mesh grid, and is arranged between the supporting network (5) and the supporting network (3); and the aggregation layer (7) is arranged between the supporting network (5) and the supporting network (6). The invention has the advantages of improving the separation effect under the condition of not increasing pressure drop.
Description
Technical field
The present invention relates to a kind of air compressor accessory, especially relate to a kind of oil-gas separating filter element of rotary jetting air-compressor.
Background technique
The function of oil-gas separating filter element be be used in the compression process to lubricate, the oil of function such as cooling, sealing separates with pressurized air.Oil after the separation is got back to head and is recycled, and the pressurized air that contains certain oil mass uses for the back level as power source, and the gas oil content after the separation is few more, and filter core pressure falls low more good more.
Oil-gas separating filter element has two kinds of forms at present: a kind of is the flat formula that twines, and the glass fiber filter paper that is about to the multilayer submicron order is wrapped on the supporting network of filter core, carries out the first time and separates, and carries out the second time through polymeric layer again and separates; Another kind is collapsible, and the glass fiber filter paper kalamein mesh grid of which floor submicron order soon is processed into accordion and is placed on the supporting network, carries out the first time and separates, and carries out the second time through polymeric layer again and separates.The flat formula filter core that twines falls higher owing to the relatively little pressure of filter area; And folding type filter element makes separating effect bad because of multilayer filter paper not being processed into accordion, but because the big pressure of its filter area falls lower.These two kinds of filter cores separate back gas oil content at 3mg/Nm
3, 0.02MPa falls in pressure.
Summary of the invention
The problem to be solved in the present invention provides a kind of oil-gas separating filter element that improves separating effect under the condition that boost pressure is not fallen.
In order to address the above problem, oil-gas separating filter element technological scheme of the present invention comprises:
A kind of oil-gas separating filter element of rotary jetting air-compressor comprises supporting network, separating layer; It is characterized in that: separating layer comprises collapsible separating layer 2, flat formula separating layer 4 and the polymeric layer 7 of twining, and collapsible separating layer 2 is at outermost surface, flatly twines formula separating layer 4 in the centre, and polymeric layer 7 is at innermost layer, wherein:
Collapsible separating layer 2 is processed into accordion by the glass fiber filter paper kalamein mesh grid of multilayer submicron order and places between supporting network 1 and the supporting network 3;
The flat formula separating layer 4 that twines is wrapped in metal knitted on the net by the glass fiber filter paper of multilayer submicron order, place between supporting network 3 and the supporting network 5;
In order to overcome the shortcoming of existing two kinds of oil-gas separating filter elements, the present invention adopts multi-stage separation: the first order is collapsible separating layer, utilizes the big advantage of accordion filter area, earlier a large amount of oil is separated out; The second level is the flat formula separating layer that twines, the oil content of separating in the pressurized gas of back because of first layer has reduced much, and the second level filter paper number of plies can reduce to five or six layers, and pressure is fallen can be very not high, separate for the third time through polymeric layer again, make separation back gas oil content can drop to 1mg/Nm
3, pressure falls less than 0.02MPa.
Compared with prior art, beneficial effect of the present invention is: improved separating effect under the condition that boost pressure is not fallen.

Embodiment
The present invention is further illustrated in conjunction with Fig. 5, Fig. 6:
Oil-gas separating filter element comprises supporting network, separating layer; Wherein: separating layer comprises collapsible separating layer 2, flat formula separating layer 4 and the polymeric layer 7 of twining, and collapsible separating layer 2 is at outermost surface, flatly twines formula separating layer 4 in the centre, and polymeric layer 7 is at innermost layer.
Collapsible separating layer 2 is processed into accordion by the glass fiber filter paper kalamein mesh grid of multilayer submicron order and places between supporting network 1 and the supporting network 3;
The flat formula separating layer 4 that twines is wrapped in metal knitted on the net by the glass fiber filter paper of multilayer submicron order, place between supporting network 3 and the supporting network 5;
As Ingersoll-rand P600 movable air compressor, to use and put down when twining formula oil-gas separating filter element (as Fig. 1, Fig. 2), the outlet oil content is higher, at 6mg/Nm
3More than, resistance rise fast, life-span＜2500h, use oil-gas separating filter element of the present invention after, oil consumption reduces, outlet oil content＜2mg/Nm
3, the life-span is brought up to＞4000h.
For another example: the 37KW stationary air compressor that Korea S produces, use flatly to twine formula oil-gas separating filter element (as Fig. 1, Fig. 2) or collapsible oil-gas separating filter element (as Fig. 3, Fig. 4) all can't resolve the high problem of outlet oil content, outlet oil content＞10mg/Nm
3, use oil-gas separating filter element of the present invention after, the outlet oil content be reduced to 3mg/Nm
3Below, working life 〉=4000h has thoroughly solved the high problem of oil consumption.
