Because filtration channel has above-mentioned spirality characteristics on the whole; Therefore the flow direction of solution to be filtered in filtration channel has along the component of chimney filter excircle rotation; Can form tangential impact to the solid impurity in the solution, thereby stop filter cake to form, reduce chimney filter outer surface filter pressure gradient; It is more balanced to make that chimney filter outer surface filter pressure everywhere distributes, and then increases filtration stability, prolongation chimney filter life-span, raising filtration flux.
Consider the requirement of bigger filter area; The interior chimney filter and outer chimney filter of at least one group of inside and outside socket are installed in the shell; Medium to be filtered from interior chimney filter and outside between the chimney filter through and go out in chimney filter and outer chimney filter advance beyond respectively in making mode with in advance the mode of going out and filter, also form described filtration channel in said baffle plate is installed between chimney filter and the outer chimney filter therein.
In order to form the filtration channel with helical form characteristics, said baffle plate is a helical baffle, the rotating shaft of this helical baffle and the central axes of chimney filter.Helical baffle can be regarded the 3D solid that is formed along a helical scanning by the cross section of a flat as, and the height of this cross section is the thickness of helical baffle, and width is the width of helical baffle.After baffle design was said structure, filtration channel promptly formed a spiral helicine passage.
Said baffle plate also can be to be made up of the lagging that polylith is arranged along the chimney filter axially spaced-apart, has different hole, position or breach on these laggings.In addition, part or all of lagging is linked to be an integral body through axial dowel, can improve the structural strength of baffle plate.Because the hole of being offered on the different laggings or the position of breach are different, when therefore hole or the breach of hole or the breach of solution to be filtered from the lagging on another piece lagging flows, certainly exist moving along chimney filter excircle direction.
The technique effect of the utility model is:
1) because pressure is the unique power that filters; Under chimney filter outer surface filter pressure everywhere distributes situation about reaching unanimity; Chimney filter flux everywhere is consistent, avoided local obstruction and decay because of surpassing critical flux or critical pressure and causing, thereby the stability of filtering can increase; In addition, because the rotation of fluid, shearing force increases, so the concentration polarization phenomenon on the filter core disappears basically, the stability of filtration also increases thereupon.
2) when pressure distribution was uneven, the excessive and most of position of chimney filter surface local pressure did not reach required pressure, so the filtration flux of the most area of chimney filter do not reach perfect condition, caused total flux to reduce; And after chimney filter outer surface filter pressure gradient was improved, filtration flux reached perfect condition.In addition, because the centrifugal force that the fluid rotation produces also acts on the surface of filter core, impel flux to increase.
3) when the filter pressure distribution everywhere of chimney filter outer surface reaches unanimity, can avoid local obstruction of chimney filter or irreversible pollution, prolong the service life of filter core.
