Description
Technical field
The present invention relates to be used for filtering the filter element of fluid, relate to a kind of fluid treatment element that comprises the filter medium of the antipriming pipe that twines central tube more specifically, have the filter element that at least one is provided with one heart around the longitudinal axis.The invention still further relates to and utilize filter element to filter the method for fluid.
Background technology
High efficient filter sound silencing element and the filter formed thus are in industry extensive application such as petrochemical industries.As in terephthalic acid (TPA) factory, terephthaldehyde's acid mother liquor filters 90% filter that adopts this form.The main feature of this filter:
1, fault rate is low.
2, maintenance cost is low.
3, cost of investment is low.
4, utilization of capacity height.
Summary of the invention
The purpose of this invention is to provide a kind of filter element, another object of the present invention provides a kind of method of utilizing filter element to filter fluid;
Filter element comprises 1) central tube;
2) central tube is provided with the antipriming pipe of 6～8 equidimensions outward;
3) the pipe lower end is provided with W type end socket, and the upper end is provided with connector;
4) W type end socket is provided with the filter cloth locking slot outside reaching and going up end connection;
Filtering coating member in filter element arranged outside of the present invention, is exactly basic filter element as filter cloth; The outer antipriming pipe of central tube is set to 6～8, and for fitting tightly, the filter cloth locking slot is twice at least between antipriming pipe and the antipriming pipe, between antipriming pipe and the central tube, considers that filter cloth is changed to make things convenient for and economic factor operated by rotary motion 2 to 4 roads.Antipriming pipe is distributed with straight pipe type, node type and three kinds of patterns of screw type, and the node type is arranged in this way, preferably faces the crest of two bellows tubes and trough mutually for being staggered; Helical pattern in this way, the screw type antipriming pipe has single head and double end, and rotary orientation has left-handed and dextrorotation; The aperture area of antipriming pipe is for contacting round lateral surface and being whole pipe range, the perforate of Any shape and any equally distributed form all are fit to the present invention, for example circular port, rectangular opening or the like, the pattern in preferred hole have the uniform circular hole of triangle and perpendicular to two kinds of the equidistant bar holes of central tube axis.The material of antipriming pipe can be a metal, also can be nonmetal.
Utilize filter element of the present invention, be equipped with suitable auxiliary equipment, as filtering the filter that housing, adapter, valve etc. just can be combined into filter liquide or gas.
Treating capacity, solid content, solid size distribution according to required filter liquide, select the filter element of some, be linked to manifold trunk by screw thread or flange connector, if filter element quantity is more, can divide into groups every group of corresponding manifold trunk, then manifold trunk is aggregated on the house steward, and be equipped with parts such as corresponding housing, valve, and form complete filter (Fig. 5), realize the purpose of efficient separating liquid.
A kind of method of utilizing the filter element filter liquide:
1, to the filter topping up, gas is discharged by emptying in the filter;
2, carry out the filter cloth pulse backblowing behind the topping up;
3, to the filter topping up, filtrate is passed filter cloth, is pooled to W type end socket by antipriming pipe, by flowing to manifold trunk on the central tube, discharges filter behind the remittance house steward then, and filter cake then is trapped in the filter cloth surface;
When 4, having served as the pressure reduction of filter element part or filter cake thickness or filtration time and reach setting value, feed and unload liquid gas the suspension in the filter is pushed back feed unit, filter element keeps certain pressure reduction simultaneously, prevents to unload liquid process filter cake and comes off;
5, after the suspension emptying, continue logically to unload liquid gas filter cake is carried out drying;
6, behind the filtration cakes torrefaction, filter cake is unloaded with blowback; Filter cake draws off back introducing cleaning solution filter cloth is cleaned, and introduces the regeneration that blow-back is finished filter cloth then, enters next the filtration and prepares;
Usually according to the needs that filter, pressure reduction is made as 0.10～0.5Mpa (G) in the setting of step 4 filter element pressure reduction, and filter cake thickness is generally 5mm～30mm, and the setting of filtration time was generally 30 minutes～60 minutes;
Treating capacity, solid content, solid size distribution according to required filtering gas, select the filter element of some, be linked on the demarcation strip in the filter housing by flange connector, blowback air nozzle of each filter element exit configuration, several nozzles constitute one group, and being connected to a blowback tracheae, all blowback air pipes are pooled on the total blowback tracheae.And be equipped with parts such as corresponding revolution blanking device, valve, pressure, differential pressure measurement and safety attachment, form complete filter (Fig. 6).Realize the purpose of entrained solids in the efficient divided gas flow.
A kind of method of utilizing the filter element filtering gas:
1, filter is inflated;
2, gas is discharged filter through filter cloth, antipriming pipe, W type end socket, central tube, and the entrained solid particle is trapped within the filter cloth surface;
3, pressure reduction of filter element (pressure reduction of inlet plenum and exhaust chamber) or dust thickness or filtration time reach when setting value, with the blowback air blowback of dividing into groups, the solid particle that is attached on the filter cloth are come off, and finish filter cloth regeneration.
Usually according to the needs that filter, pressure reduction is made as 0.10～0.30Mpa (G) in the setting of filter element pressure reduction, and dust thickness is generally 5mm～30mm, and the setting of filtration time was generally 30 minutes～60 minutes;
The solid particle that removes falls into filter inlet plenum bottom, delivers to after-treatment system by rotary valve or suitable device for discharging.
Selecting for use of different types of the present invention, unlike material filter element, to select according to gas permeability of need filter medium physics, chemical characteristic, solid content, filter pressure, temperature, filter cake etc., to reach optimum filter effect, filter element of the present invention has characteristics such as long service life, effective filtration area is big, the high filter cloth regeneration of filter effect is effective;
