Abstract
The invention relates to a metallic fiber sintered felt composite filtering element, which comprises a metallic fiber sintered felt and a layer of filter film which consists of a metal film and an organic film or a ceramic film and is arranged on the metallic fiber sintered felt. The metallic fiber sintered felt composite filtering element is used to optimize two indexes of filter capacity and filter element strength, ensure the mechanical strength of a filter element, nearly not to generate pressure loss, and further ensure not to influence the circulation; and the function of separating solid particles is borne by the metal film, the organic film or the ceramic film which is sintered with a porous substrate together, and the separation accuracy can reach submicron class; because the film is thin, the blockage is not easy to happen, the filter effect is better, and the accuracy is higher; and when the film is backwashed for regeneration, filtercake impurity liquid is easy to fall off from the surface of the film so as to prolong the service life of the filtering element.
Description
Technical field
The present invention relates to a kind of fluid filter element that is used to filter various materials and separating micro-diameter particles, be specially a kind of metallic fiber sintered felt composite filtering element.
Background technology
At present, the filtration fraction of employed metallic fiber sintered felt filter element all is a symmetrical structure in the industrial production, the filtering accuracy minimum can only be accomplished 1 micron, and circulation is extremely low when adopting the high accuracy filter element, filter material thickness is thicker, and enter wherein as particulate and stop up easily, and easy to clean not after stopping up, thereby influence filter effect and filter efficiency, shorten the service life of filter element.
Summary of the invention
The technical problem that the present invention solves provides a kind of filtering accuracy height, reduces the accumulation obstruction, improves filter efficiency, prolongs the filter element metallic fiber sintered felt composite filtering element in service life.
The present invention adopts following technical scheme:
The present invention includes metallic fiber sintered felt and be arranged on the filter membrane that the one deck on the metallic fiber sintered felt is made of metal film, organic film or ceramic membrane.
Metallic fiber sintered felt of the present invention is cylindric, on the cylindrical metal fiber sintering felt serving inner surface or outer surface be provided with the filter membrane that one deck is made of metal film, organic film or ceramic membrane.
The invention has the beneficial effects as follows: it is metallic fiber sintered felt as base material that the present invention selects gross porosity footpath material for use, filter membrane in substrate surface spraying or the metallic film in the fine aperture of sintering one deck, organic film or ceramic membrane formation, thereby optimize filter capacity and two indexs of filer element strength, when guaranteeing the filter core mechanical strength, produce pressure loss hardly, thereby guarantee that its circulation is also unaffected; Function of separating solid particles, then by bearing with porous substrate sintering metallic film, organic film or ceramic membrane together, separation accuracy can reach submicron order, because this layer film thinner thickness, thus be difficult for blocking, and also filter effect is better, precision is higher, in the time of backwash and regeneration, filter cake impurity liquid comes off from its surface easily, thereby has prolonged the service life of filter element.

The specific embodiment
As shown in Figure 1, filter element of the present invention is made base material by rough grade tabular metallic fiber sintered felt 1, surface or lower surface spraying thereon or the ultra-thin metal film of sintering last layer, and ceramic membrane or organic film are as filter membrane 2.
As shown in Figure 2, filter element of the present invention is made base material by rough grade tubular metallic fiber sintered felt 1, spraying or the ultra-thin filter membrane 2 of sintering last layer on barrel outer surface or the inner surface, and filter membrane 2 is a metal film, ceramic membrane or organic film.Present embodiment is at outer surface spraying or sintering filter membrane 2.
The present invention optimizes filter capacity and filer element strength, when guaranteeing the filter core mechanical strength, produces pressure loss hardly, thereby guarantees that its circulation is also unaffected; Function of separating solid particles, then by bearing with porous substrate sintering metallic film, organic film or ceramic membrane together, separation accuracy can reach submicron order, because this layer film thinner thickness, thus be difficult for blocking, and also filter effect is better, precision is higher, in the time of backwash and regeneration, filter cake impurity liquid comes off from its surface easily, thereby has prolonged the service life of filter element.

As shown in accompanying drawing 3,4:
1-1 is the metallic fiber sintered felt filter element curve of 3.0 microns of traditional filtering accuracies among the figure;
1-2 is the metallic fiber sintered felt filter element curve of 5.0 microns of traditional filtering accuracies among the figure;
1-3 is the metallic fiber sintered felt filter element curve of 10.0 microns of traditional filtering accuracies among the figure;
2-1 is the metallic fiber sintered felt composite filtering element curve of 0.5 micron of filtering accuracy among the figure;
2-2 is the metallic fiber sintered felt composite filtering element curve of 1.0 microns of filtering accuracies among the figure;
