Description
Technical field
The present invention relates to a kind of filter and filter element thereof, be specifically related to structure and the inner filter thereof of filter.
Background technology
Existing gas-filtering device generally adopts following structure: gas-filtering device comprises shell, be arranged on the orifice plate in this shell and be arranged on filter element (current filter element employing cloth bag or the screen pipe on orifice plate, screen pipe can be divided into again sintering metal porous material screen pipe, sintered ceramic porous material screen pipe, organic porous material screen pipe), in shell, be positioned at orifice plate top and form pure qi (oxygen) chamber, in shell, be positioned at orifice plate below and form former air cavity, shell be provided with the air inlet of former air cavity conducting and with the exhaust outlet of pure qi (oxygen) chamber conducting, the bottom of shell is convergence shape and forms dust stratification ash discharge portion.During use, gas to be filtered enters former air cavity from air inlet, and then the clean gas after logical filter element filtration enters pure qi (oxygen) chamber, finally from exhaust outlet, discharges; The dust filtering down falls into the dust stratification ash discharge portion of outer cylinder body bottom, finally removal from gas-filtering device.Existing liquid end-filtration device (" end-filtration " also claims " dead-end filtration ", is that filtering in industry is the known concept that is different from " cross-flow filtration ") has also adopted and the essentially identical structure of above-mentioned gas filter and operation principle mostly.
For above-mentioned filter, in order to improve its filtration treatment ability, the way of taking at present mainly: the filter of the first, building large-scale (it is many that floor space is large, filter element is installed quantity); The second, increase the filter area (for example increasing the length of cloth bag or screen pipe) of filter element; Three, increase the number of devices of filter, realize many and work simultaneously.Above-mentioned first and third kind of way all needs to install and use place for filter provides larger area, tends to relate to the series of problems such as factory building reorganization and expansion, therefore cost is higher when concrete application; There is the problems such as filter element manufacture difficulty is larger in the second way.
Summary of the invention
Technical problem to be solved by this invention is: a kind of novel filter of constructing is provided, is conducive to improve total filter area of its inner filter element under unit occupied area; A kind of filter for this filter also will be provided in addition.
Filter of the present invention comprises shell and is arranged at least one group of filter element in shell, between described shell and filter element, by filter element mounting and positioning device, be connected and form the first space and the second space of separating, the transmission of thing to be filtered occurs in the first space, the transmission of filtrate occurs in second space, every group of filter element includes to be erect the conduit arranging and is spaced and is arranged on this supravasal filter along catheter length direction, one end of described conduit be arranged on filter element mounting and positioning device and with described second space conducting, the other end of conduit is free end or is connected with pipe end positioner, on the sidewall of conduit, be furnished with the entrance with the inner chamber conducting of this conduit, it is sheet that described filter has an integral body, inner is the filter house of cavity and the connecting portion that is positioned at this filter house one sidepiece, described filter house is arranged on the sidewall of conduit by connecting portion, connecting portion is provided with connection filter house inner chamber and exports with the filtrate of corresponding entrance on duct wall, the outer surface that plays the front and back two panels of main filtration on filter house is filtering surface, angle >=0 between described filtering surface and conduit axis ° and≤30 °.
The filter element that above-mentioned filter of the present invention adopts comprises to be erect the conduit arranging and is spaced and is arranged on this supravasal filter along catheter length direction, while needing, by adjusting the length of conduit and the quantity of filter, increase or reduce the total filter area of filter element in filter, can not be subject to the impact of filter floor space; Filter element adopts filter, and the angle design of parallel or smaller angle between described filtering surface and conduit axis, can reduce the area occupied projected area of horizontal plane direction () of filter element, thereby increase filter element layout quantity, and can reduce and stress deformation, the fracture equivalent risk that filter element is brought is installed because of cantilevered.Visible, this filter can be issued in less floor space larger total filter area, thereby promotes the filtration treatment ability of filter.Above-mentioned filter of the present invention both can be used for gas filtration, also can be used for liquid filtering.
In above-mentioned filter, the profile of the filter house of described filter is preferably rectangle, connecting portion is formed on a sidepiece of this filter house, in this sidepiece, be provided with the long and narrow outlet of filtrate of extending along this sidepiece, the outer rim of this sidepiece is provided with location sealing boss, on the sidewall of described conduit, is detachably provided with location sealing boss is fastened on to the gland on duct wall.Now, the structure of filter should be mutually: filter have an integral body be sheet, inner be the filter house of cavity and the connecting portion that is positioned at this filter house one sidepiece, the profile of described filter house is rectangle, described connecting portion is formed on a sidepiece of this filter house, in this sidepiece, be provided with the long and narrow outlet of filtrate of extending along this sidepiece, the outer rim of this sidepiece is provided with location sealing boss.This structure filter not only has that filter area is large, structural strength advantages of higher, also can be arranged on conduit easily simultaneously.
Filter in above-mentioned any filter of the present invention is preferably by sintering metal porous material or consist of sintered ceramic porous material.Adopt sintering metal porous material or by sintered ceramic porous material as filter material, range of application wider (such as the filtration of high temperature air filtration, corrosive substance etc.), long service life, filters into precision guaranteed.Selecting on the basis of this filter material, filter can further be made through sintering by the one-body molded base of the static pressure such as powder, length, the width of its filter house are 450～900 millimeters simultaneously, 30～70 millimeters of the thickness of filter house, the wall thickness that plays the front and back two panels of main filtration on filter house is 3～10 millimeters.The one-body molded base of the static pressure such as powder is manufactured filter element (being powder metallurgic method) through sintering and than additive method, is had the advantages such as production efficiency is high, constant product quality.It specifically need to be one-body molded for intermediate blank (being the one-body molded base of the static pressure such as powder) by powder stock by isostatic pressing mold, and then sent into and in sintering furnace, carry out high temperature sintering and finally obtain filter product.Consider filter efficiency, current factors such as manufacture difficulty and determine the length of above-mentioned filter house, width are set as to 450～900 millimeters in conjunction with lot of experiments, the thickness of filter house is set as 30～70 millimeters, and it is comparatively rational that the wall thickness that plays the front and back two panels of main filtration on filter house is set as 3～10 millimeters.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.The aspect that the present invention is additional and advantage in the following description part provide, and part will become obviously from the following description, or recognize by practice of the present invention.
