Abstract
The utility model relates to a fluid filter which is especially suitable for filtering the carbon particle of the exhaust gas of a diesel engine and simultaneously suitable for filtering other kinds of fluids. The utility model is mainly composed of multilayer cylinder-shaped corrugated tube filtering elements, multilayer cylinder-shaped flat sheet filtering elements, a central tube and a housing. The innermost layer cylinder of the fluid filter is the flat sheet filtering element which is welded together with the central tube, and the outermost layer cylinder is also the flat sheet filtering element which is welded together with the inner surface of the housing; the multilayer cylinder-shaped corrugated tube filtering element and the cylinder-shaped flat sheet filtering element form an alternative jacket layer structure in the shape like the Chinese character 'zhi'. The cylinder-shaped plain edges of both ends of the corrugated tube filtering element are aligned to the single edge of the nested cylinder-shaped flat sheet filtering element to be welded together to form a seal opening in the shape like the Chinese character 'zhi '; both ends of the 'zhi'shape are a fluid inlet end and a fluid outlet end. The fluid filter has large filtering area, high sewage holding capacity and small volume.
Description
Technical field

Background technique
In the industrial field 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, farm machinery and boats and ships contains a large amount of carbon microspheres, causes serious environmental to pollute.And the fluid filter that is used for this respect at present is not ideal enough.The porcelain filter gas permeability is not high, fluid-pressure drop is big, pollutant holding capability is little; The bag filter of steel fiber, tubular filter or pleat page filter, the filter area in the per unit volume cause shortcomings such as volume is big, filter area is little than little.
The model utility content
The purpose of this utility model is to provide a kind of diesel motor exhaust carbon microsphere that is specially adapted to filter at the defective of prior art existence, also is applicable to the fluid filter that filters other kind fluid simultaneously, and its filter area is than big, and pollutant holding capability is big, and volume is little.
Fluid filter of the present utility model is the improvement to CN200310117410.6.
Fluid filter of the present utility model is made of multi-layer cylinder shape corrugated tube filter element, multi-layer cylinder shape flat panel filter element, center tube and shell; Its innermost layer cylinder is the flat panel filter element, welds together with center tube; Its outermost surface cylinder also is the flat panel filter element, welds together with inner surface of outer cover; Multi-layer cylinder shape corrugated tube filter element and cylindrical shape flat panel filter element are " it " font and replace jacket structure; The flat limit of cylindrical shape at corrugated tube filter element two ends and the cylindrical shape flat panel filter element of suit monolateral alignd to weld together and is " it " font and seals, and " it " font two ends are fluid inlet end and fluid outlet.
The shape of cylindrical shape corrugated tube filter element, its two ends are the flat limit of cylindrical shape, and the centre is a waveform, and two to hold hem width level with both hands be 3-8mm.
Cylindrical shape flat panel filter element it be shaped as cylindrical.
The number of plies of cylindrical shape corrugated tube filter element+cylindrical shape flat panel filter element is decided according to the required area of fluid filter; The stack height A of described cylindrical shape corrugated tube filter element and dull and stereotyped filter element is 2～10mm.
Corrugated tube filter element corrugation pitch B decides according to the filtering material that adopted and fluid filter length, and cylindrical shape corrugated tube filter medium corrugation pitch B is 4～20mm.
Because the improvement of structure, the utility model is compared with application for a patent for invention CN200310117410.6 and had following advantage: welding procedure is directly adopted in combining between a. filter element group and the shell, and need not adopt high-temperature seal adhesive, makes that combination is more reliable; B. the overall structure of filter element group is a cylindrical shape, and the filter element compressive strength that makes is higher; C. the overall structure of filter element group is a cylindrical shape, can enhance productivity greatly.

Embodiment
As shown in Figure 1 and Figure 2, fluid filter of the present utility model is made of multi-layer cylinder shape corrugated tube filter element 1, multi-layer cylinder shape flat panel filter element 2, center tube 5 and shell 6.Its innermost layer cylinder is a flat panel filter element 2, welds together with center tube 5; Its outermost surface cylinder also is a flat panel filter element 2, welds together with shell 6 internal surfaces, has just constituted a complete filter.
As shown in Figure 3, the shape of cylindrical shape corrugated tube filter element, its two ends are the flat limit of cylindrical shape, and the centre is a waveform, and two hold the about 5mm of hem width level with both hands.
As shown in Figure 4, cylindrical shape flat panel filter element its be shaped as cylindrical.
As Fig. 5, shown in Figure 6, the filter element group is " it " font by multi-layer cylinder shape corrugated tube filter element (1) and cylindrical shape flat panel filter element (2) and replaces the jacket structure formation.The flat limit of cylindrical shape at corrugated tube filter element (1) two ends and the cylindrical shape flat panel filter element (2) of suit monolateral alignd to weld together and is " it " font and seals, " it " font two ends are fluid inlet end (3) and fluid outlet (4), to form the filtration channel of fluid turnover.The number of plies of cylindrical shape corrugated tube filter element (1)+cylindrical shape flat panel filter element (2) is decided according to the required area of fluid filter; The value of jacket layer height A is between 2～10mm, and corrugated tube filter element (1) corrugation pitch B decide according to the filtering material that adopted and fluid filter length, is worth between 4～20mm.
