Abstract

Creation of a spacially ordered system of hollow polymer fibres and fixation thereof in polymer edges (selvedges) made of a polymer are carried out in a combined device employing immediately successive steps in such a way that the hollow polymer fibres are wound off from separate creel reels and the entire hollow fibre system is parallelly fed in an ordered state directly into an open mould located in an injection module. After closing the mould, a reactive mixture is injected into the mould to form the polymer edges, which fix the position of the hollow polymer fibres. The production of the primary element of the heat-transfer surface area for a heat-exchanger or the primary element for the separation module is finished by separating a part of the edges in the direction crosswise to the direction of the hollow polymer fibres by cutting or by a combination of cutting and breaking.

Description

A METHOD OF MANUFACTURING A PRIMARY CELL OF A HEAT EXCHANGE SURFACE OF A HEAT EXCHANGER OR A FILTERING SURFACE OF A SEPARATION MODULE BASED ON HOLLOW POLYMEROUS FIBRES AND A PRODUCTION LINE FOR IMPLEMENTING THE METHOD

Field of invention

The invention relates to a method for producing a primary element of a heat exchanger heat-transfer surface area or of a filtration surface area of a separation module on the basis of hollow polymer fibres having compact or porous walls, the method of production consisting in fixing the system of hollow polymer fibres in a polymer edge. Further, the invention relates to a production line for carrying out the production method.

Description of the prior art

Ordered or disordered systems of hollow polymer fibres are used as efficient heat-transferring (heat exchaning) or separation (filtration) surface areas in heat- exchangers and separation (filtration) modules in a wide application area. A general problem of design and production of the heat-exchangers and separation modules based on hollow polymer fibres is inlet (entry) and fixation of the hollow polymer fibres so that the system of capillary fibre cavities could be connected tightly to the circulation loop of the liquid or gas medium.

For fixation of the hollow polymer fibre ends and creation of flanges, procedures based on filling thereof with solidifying (hardening) polymers are used. By cutting the flange the inlet of the hollow polymer fibres opens, thus enabling a connection to the circuit of the appropriate medium. This process is described, for instance, in the Japanese patent JPH 62160108 or the Swedish patent SE 397638. The regular arrangement of the system of hollow polymer fibres during their potting (embedding) can be achieved by weaving thereof and by creating defined positions of the separate fibres, as described in the USA patent U.S. 5922201. The fixation of the positions of the pre-cut separate hollow polymer fibre ends can be obtained by applying, for instance, hot melt thermoplastic adhesive in such a way that a sealed space is created for subsequent injection, for instance of reactive components, thus forming a flange, as described the USA patent U.S. 8864990.

The desired arrangement of the fibres at the end of the fibre bundle can also be achieved by enclosing the fibre bundle with an elastic collar and by mutual turning of the bundle and the collar, as described in the Czech patent CZ 304270. Winding of the hollow polymer fibres on a firm frame followed by their potting with a polymer material in areas of thinned shoulders is the subject of the British patent GB 1472227. An arrangement of the hollow fibres in a vertical position followed by potting thereof with epoxy resin is described in the Czech patent CZ 304191 .

An auxiliary fixation of the ends of the hollow polymer fibre bundle with wax followed by potting thereof with a polymer material is described in the U.S. Patent No. 5639373.

Fixing the ends of the hollow polymer fibre bundle by centrifugal casting of cyclo- olefin is described in the Japanese patent JPH 06170177.

The tubular arrangement of the hollow polymer fibres in the heat-transfer surface area and creation of the flanges are achieved by drawing the separate fibres through distance circular plates placed in a cylindrical mould and by subsequent potting thereof with a reactive mixture, the reactive mixture being injected into the mould through a central gating system according to the Japanese patent application JP 201 1 167580. The regular arrangement of the hollow fibres is achieved by drawing the fibres through a perforated plate and subsequent imbedding thereof in a horizontal position according to the international patent application WO 9533548.

However, the above mentioned procedures are complicated for use in mass production conditions, particularly when a regular arrangement of hollow polymer fibres in heat-transfer surface areas of heat-exchangers or in filtration surface areas of separation modules is needed.

Nature of the invention

The shortcoming of the above prior art can be eliminated to a great extent by using a method for production of the primary element of the heat-exchanger heat- transfer surface area or filtration surface area of the separation module on the basis of hollow polymer fibres having compact walls or walls having porous structure according to the invention, the method of manufacture being, in a similar way as known methods, based in principle on fixation of the hollow polymer fibre system in the polymer edge.

The nature of the invention is that the ordered system of the hollow polymer fibres is created and the fibres are fixed in the polymer edge by performing directly interconnected steps as follows:

a) the hollow polymer fibres are wound off either from separate creel reels or from a package of woven hollow fibres and the entire system of the hollow fibres is parallelly fed in an ordered state directly into an open injection mould;

b) after closing the mould, the reactive low viscosity mixture is injected into the mould to create at least one polymer edge for fixing the position of the hollow polymer fibres; c) when the mould cavity containing the hollow polymer fibres has been filled with the reactive mixture and the polymerisation process has been completed, the polymer edge oriented in the crosswise direction to the led-in hollow fibre system or the edge about the whole circumference of the led-in system of the hollow polymer fibres is formed. The edge fixes the position of the freely led-in ordered hollow polymer fibres in such a way that the space between separate hollow polymer fibres is sealed and simultaneously regular surface areas defining the shape of the polymer edge are created;

d) after opening the mould, flashes of the mould gating and venting systems are removed;

e) the entire system of the hollow fibres including the polymer edge thus created is drawn into the stabilization zone outside the shape mould cavity without interrupting feeding of the system of hollow polymer fibres from the reels; f) in the stabilization zone the edge position is fixed while the lengths of the hollow fibres of the primary element produced can be controlled by setting the distance between the position of the edge fixation and the shape mould cavity;

g) subsequently, in the distance from the first edge defined in this manner, further edge is created on the system of parallel hollow polymer fibres using the same procedure and the steps according to a) to d), also in the crosswise direction, or another edge about the entire circumference of the led-in system of the hollow polymer fibres;

h) the system of ordered hollow polymer fibres with polymer edges is wound off from the mould in continuous bands, thereupon the entrance into the inside of the hollow polymer fibres is uncovered without limiting the pass-through ability thereof by separating a part of the edges in the direction crosswise to the direction of the system of hollow polymer fibres by cutting or by a combination of cutting and breaking. Thus a separate primary element of the heat-exchanger heat-transfer surface area or a primary element of the filtration surface area of the separation module based on hollow polymer fibres is created;

i) in conclusion the primary elements are bonded into blocks and the blocks are fitted with flenges.

Thus the process of production of the basic heat exchanger module (zakladni modul) or the basic separation module is completed.

As hollow polymer fibres for the production of the primary element for the heat- exchanger heat-transfer surface area hollow fibres with compact walls will be used, as hollow polymer fibres for the production of the primary element filtration surface area for the separation module hollow fibres with microporous walls will be used. These hollow polymer fibres are made of a polymer material selected advantageously from a group comprising polypropylene (PP) including polypropylene copolymers, polycarbonate (PC), PC/ABS copolymer, polyamide (PA) and PA/ABS copolymer.

In order to create edges a compound from a group including dicyclopentadiene (DCPD) with a catalytic system based on molybdenum compounds, a catalytic system based on wolfram compounds or a catalytic system based on ruthenium compounds, further two-component epoxy casting substances, two-component acrylate casting substances and two-component polyurethane mixtures will be used as a reactive low- viscosity mixture for injection under low pressure of 1 to 10 bars.

The production line for carrying out the method according to the invention contains an unwinding facility comprising a creel with a reel system or an unwinding reel for wind-up of woven hollow fibres followed by an injection module comprising a tensioning mechanism, an injection mould with stabilization zones including positioning pins for fixing the edge position, a mould carrier and a clamping plate for fixing the mixing head of the reactive mixture dosing unit.

The injection mould can have one of the following designs:

- injection mould for creating one edge perpendicular to the direction of the hollow fibres,

- injection mould for creating one edge about the circumference of the heat-transfer or filtration surface areas using one injection of the reactive mixture,

- injection mould for creating n couples of edges perpendicular to the direction of the hollow fibres by injecting reactive mixture from one or more mixing heads, the distance between the edge couples defining the operation length of the heat-transfer or filtration surface areas with the separate edges in the edge couples being close to each other,

- injection mould for creating n couples of edges about the circumference of the heat- transfer or filtration surface areas with an injection of the reactive mixture from one or more mixing heads.

In order to achieve an ordered state of the hollow polymer fibres in the injection mould a tensioning mechanism is advantageously combined into one set, a part of which is also a fibre guiding comb, anchor comb of the injection mould stabilization zones and the injection mould shape part including the gating system. Auxiliary openings in the injection mould cavity and in the edges can be advantageously created for positioning the edge with the hollow fibres on the pins of the injection mould stabilization zone.

In order to seal the hollow polymer fibres against flow of the reactive mixture outside the mould shape cavity and against an undesirable deformation of the hollow polymer fibres during injection moulding it is advantageous to fit the injection mould with a replaceable elastic profiled sealing.

The solution according to the invention brings a number of advantages, of which those shown below can be given as the most significant:

j) by way of an efficient arrangement and an incorporation of the separate technological steps into the line, conditions for automation of the whole manufacturing process have been created;

k) the design of the manufacturing line and the method of preparation makes possible to process individual hollow polymer fibres wound off the creel reels as well as hollow fibres in the form of woven materials;

I) the possibility of processing individual hollow polymer fibres brings a significant economic advantage over processing of woven hollow fibres. Weaving of hollow fibres is a slow, technically problematic (a damage of the fibres can occur) and expensive process;

m) the method of manufacture and design of the manufacturing line enable a great processing variability with respect to choice of materials for production of hollow polymer fibres and polymer edges of the primary elements. n) the method of manufacture and design of the manufacturing line permit a great processing variability with respect to choice of performance of the heat- transfer or separation surface areas of the primary element (variability in the number, length and diameter of the hollow polymer fibres);

o) the method of manufacture and design of the manufacturing line enable a great processing variability with respect to choice of shape of the primary element polymer edges (crosswise edges or edges about the circumference, as well as number of the edges in the mould can be chosen).
