Abstract
The present invention relates to a fluid filter chiefly comprising a filtering element and a housing, wherein the filtering element is formed by the method that a corrugated sheet filtering medium and a flat sheet filtering medium present an alternative laminated structure with a Chinese character 'zhi' shape. The corrugated sheet filtering medium has the shape that both ends are provided with flat-straight edges and the middle is provided with a wave-shaped sheet, wherein the flat-straight edges of the corrugated sheet filtering medium are lined up with the same-width single edge of the flat sheet filtering medium to be welded together to present a seal with a Chinese character 'zhi' shape; both ends of the Chinese character 'zhi'-shaped are provided with a fluid inlet end and a fluid outlet end in order to form a filtering path for the inlet/outlet of the fluid. The flat-straight edges on both ends of the corrugated sheet filtering medium can be positioned in the center position of the wave shape, and also one end can be positioned on the upper part of wave shape, and the other end is positioned on the lower part of the wave shape. Sealing gums are coated between both sides of the filtering element and the side surface in the housing to prevent the leakage of the fluid containing the dust. The fluid filter of the present invention is especially suitable for filtering the carbon particles of the exhaust gas of diesel engines and simultaneously is suitable for filtering other kinds of fluids.
Description
Technical field
The invention belongs to the filtering flow field, more specifically to a kind of fluid filter.
Background technology
In the industrial circle of current each class, be the gas solid separation of finishing fluid, liquid-solid separation or gas-liquid separation, extensively adopt leaf filter, bag filter, tubular filter or pleat page filter.The filter of this many kind has different characteristics separately, therefore is suitable for different types of filtering flow.
The diesel engine emissions tail gas discharged that is used for automobile, engineering machinery, municipal machinery, agricultural machinery and boats and ships contains a large amount of carbon particulates, causes serious environmental to pollute.And the fluid filter that is used for this respect at present is not ideal enough, as the ceramic filter gas permeability is not high, fluid-pressure drop is big, pollutant holding capability is little; Filter area in the metal fiber filter unit volume causes shortcomings such as volume is big, filter area is little than little.
The utility model content
The invention provides a kind of fluid filter, be particularly suitable for the diesel motor exhaust carbon particulate and filter, also be fit to the filtering flow of other kind simultaneously.
Fluid filter of the present invention mainly comprises filter element and shell (5), filter element is " it " font alternate laminated structure by corrugated sheet filter medium (1) and flat panel filter medium (2) and constitutes, the shape of corrugated sheet filter medium (1) is that two ends are flat side, the centre is the waveform plate, the flat side at its two ends can be in corrugated centre position, shown in Fig. 2 B; Also can be in corrugated top by an end, an other end is in corrugated bottom, shown in Fig. 2 A.The flat side of corrugated sheet filter medium (1) is " it " font and seals with aliging with the flat panel filter medium (2) of width monolateral to weld together, " it " font two ends are fluid inlet end (3) and fluid outlet (4), to form the filtration channel of fluid turnover, shown in Figure 1A and Figure 1B.Total number of plies of corrugated sheet filter medium (1) and dull and stereotyped filter medium (2) is decided according to the required area of fluid filter; The value of stack height H is between 2～10mm, and the corrugation pitch L of corrugated sheet filter medium (1) decide according to the filter media material that adopted and fluid filter length, is worth between 4～20mm.Fig. 3 is by multilayer corrugated sheet filter medium (1) and dull and stereotyped filter medium (2) the 3D view of one group of filter element constituting of stack alternately, and filter element is compressed up and down in the back insertion shell (5), as shown in Figure 4 and Figure 5.Scribble fluid sealant between the both sides of filter element and shell (5) medial surface, with the leakage of control dust-laden fluid.The fluid sealant kind that is adopted can be decided according to the condition of work of fluid filter.This fluid filter profile has circle, ellipse and rectangle etc.
Because the uniqueness of structure makes the present invention have following advantage: the filter area ratio in the unit volume is up to 0.6～0.8m
2/ L, filter element compressive resistance height, anti-current body impact is good, fluid-pressure drop is little, pollutant holding capability is big etc.

The specific embodiment
Embodiment: Diesel engine car tail gas carbon particulate filter
Engine displacement: 2.0L
Fluid filter specification: φ 130 * 200
Filter area: 1.5m
2
Corrugated sheet filter medium (1) and flat panel filter medium (2): refractory metal fiber sintering felt serving, width 200mm, thickness 0.3mm
Fluid filter shell: stainless steel tube φ
In130 * 220 (length) * 2 (wall thickness)
The stack height H=3.5mm of corrugated sheet filter medium (1) and dull and stereotyped filter medium (2), the corrugation pitch L=8mm of corrugated sheet filter medium (1)
Preparation method:
1) the metallic fiber sintered felt broad ways is pressed into the corrugated sheet filter medium (1) shown in Fig. 2 A or Fig. 2 B, the flat limit of 5mm is reserved at two, and the crest height of corrugated sheet filter medium (1) is 3.2mm, and corrugation pitch is 8mm.
2) adopt resistance welding technology, the flat side of corrugated sheet filter medium (1) is welded together with monolateral alignment the with the flat panel filter medium (2) of width.
3) corrugated sheet filter medium (1) and dull and stereotyped filter medium (2) that monolateral welding is good along its length, pressed φ
InThe width dimensions shearing blanking of 130 circle cross section differing heights, folded neat back becomes a circular cross section.
4) press shown in Figure 1A, the order of connection that the flat panel filter medium (2) and the another side of corrugated sheet filter medium (1) are pressed " it " shape, alignment welding successively.
5) filter element stack after will all welding is compacted into cylinder together, smears one deck inorganic high-temp fluid sealant on cylindrical surface, inserts stainless steel tube shell (5), and shell (5) two ends stay the limit to equate.After the adhesive curing to be sealed, just finished the making of fluid filter.
