Abstract
The invention discloses a filtering element, which relates to a filtering element, and the invention aims to provide the filtering element with high porosity, small volume, stable filtering precision and long service life. The invention adopts the technical proposal that the filtering element comprises a filtration medium, and the filtration medium is an iron-chromium-aluminum fiber sintered felt or an iron-chromium-aluminum sintered net. The filtration medium has a corrugated cross section. The invention is used for filtering devices of coal gasification equipment.
Description
Technical field:
The present invention relates to a kind of filter element, particularly the filter element of coal gasification apparatus use.
Background technology:
Employed flying dust filter element in the gasification unit of coal gasification apparatus, because filter element is in the environment of high pressure, high temperature, high corrosion, all adopt the ceramic post sintering filter element both at home and abroad, the major defect of this ceramic filter element is, (1) porosity is low, thereby causes the filter volume big, (2) filtering accuracy instability, (3) easily broken, the life-span is short.
Summary of the invention:
The purpose of this invention is to provide a kind of porosity height, volume is little, filtering accuracy is stable and the filter element of long service life.Technical scheme of the present invention is that a kind of filter element comprises filter medium, it is characterized in that: described filter medium is iron-chromium-aluminum sintering felt or siderochrome aluminum sinter net.It is corrugated that described filter medium is that cross section is.The present invention has the porosity height compared with the prior art, volume is little, the remarkable advantage that filtering accuracy is stable and the life-span is long.
Description of drawings:
Fig. 1 is a filter element semi-section structural representation of the present invention, and Fig. 2 is the A-A profile of Fig. 1, and Fig. 3 is the semi-section structural representation of corrugated filter element, and Fig. 4 is the B-B cutaway view of Fig. 3.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the present invention is described in detail, for the problem that porosity is low and the life-span is short that solves existing ceramic filter, the fibrofelt that the present invention adopts the Aludirome fiber to be paved into certain bed thickness is made sintering felt or sintering net by high temperature sintering, with above-mentioned iron-chromium-aluminum sintering felt (net), be arranged on the outer surface of circular skeleton 2, form filter element.The filter area of this barrel type filtering element less (referring to Fig. 1,2).In order to increase filter area, reduce the volume of filter, iron-chromium-aluminum sintering felt can be folded into cross section is that corrugated is arranged on skeleton 4 surfaces, the filter element that this corrugated iron-chromium-aluminum sintering felt 3 is made, its filter area is big, and the volume of filter less (referring to Fig. 3, Fig. 4).This iron-chromium-aluminum sintering felt (net), be to form with metallic fiber shop system sintering, its aperture is by the decision of the diameter of fiber, filtering accuracy is high and stable, porosity height, good permeability, more powder sintered filter element improves 30-100 doubly, the high 3-6 of pollutant holding capability doubly and has excellent decay resistance, can be under strong acid sulfur-bearing and sulfide environment long-term stable operation.
Claims (2)
1, a kind of filter element comprises filter medium, it is characterized in that: described filter medium is iron-chromium-aluminum sintering felt or siderochrome aluminum sinter net.
2, filter element as claimed in claim 1 is characterized in that: it is corrugated that described filter medium is that cross section is.
