Abstract

Use: to separate heterogeneous systems. SUMMARY OF THE INVENTION: The cylindrical body is closed by a lid with a nozzle for permeate withdrawal. A flat sheet membrane is glued sinusoidally in the permeable shell of the membrane block, glued along the lateral edges with a drainage sheet to form a packet of parallel pockets with strips of turbulator installed between them. In this case, the membrane unit sits on an elastic gasket installed around the perimeter on supporting platforms with stiffening ribs, blocking the body into two chambers, communicating with each other only through slots between pockets, laid by strips of a turbulator. 1 s P. f-ly, 4 ill.

Description

The invention relates to membrane mass transfer structures. devices, namely, to the design of membrane apparatus of the flat-chamber type. ..-

Experience in the practical use of membrane mass transfer devices shows that the most widely used are roll, hollow-tube, tubular and flat chamber devices, the advantage of which is determined by the use of a flat sheet membrane. :

The manufacturing technology of such a membrane is the simplest; the quality can be easily and reliably controlled. It is possible. .

The purpose of the invention is to increase the productivity and reliability of the apparatus, reduce the weight of the structure, assembly and disassembly technologies with the possibility of repair in case of damage (rupture) of the membrane, which allows the construction and operation of devices with a large area of flat sheet membranes.

This goal is achieved by the fact that the membrane apparatus, consisting of a detachable body with fittings for the input of the separated mixture and the output of products, a membrane unit, in the capsule of which a flat semipermeable membrane is sinusoidally glued along the lateral edges with a drainage inside and forming a packet of parallel pockets with laid between the strips of the turbulator, it allows you to easily and quickly make repairs in case of damage. (rupture) of the membrane ..

This is achieved by eliminating the malfunctioning pocket from work — by gluing the drainage sheet along the top edge of the outlet, or by any other means / - block the channel with a seal when laying, which does not require capital costs for repair or replacement of the element,

Reducing the weight of the apparatus is achieved by the fact that the outer supporting body has a cylindrical shape, as the most rational for vessels operating

a luminaire inside which a lightweight chamber type block is placed — the most technologically advanced for devices with a large area of flat sheet membranes.

In FIG. 1 schematically shows the proposed apparatus, a longitudinal section; in FIG. 2 is a section A-Ana of FIG. 1; in FIG. 3 is a longitudinal section of FIG. 1 with emergency rupture of the membrane (arrows indicate the samples in the mixture to be separated through the membrane rupture hole) - the place of gluing (repair option) of the faulty pocket along the upper edge of the outlet of the drainage sheet; in FIG. 4 is a section B-B in FIG. 2, indicating the place of gluing of the lateral edges of the membrane and drainage sheets with the formation of parallel pockets according to the proposed assembly technology of the membrane block.

The apparatus consists of a cylindrical body 1 with an inlet pipe 3 and an outlet pipe 4, a membrane unit 6.

The housing 1 is closed by a cover 2 with a nozzle 5 for discharging permeate. In the permeable shell 15 of the membrane unit b, a flat sheet membrane 8 is laid sinusoidally, glued along the lateral edges with a drainage sheet 9, forming a packet of parallel pockets 16 with stripes of turbulator arranged between them 10. Drainage sheets 17 are laid at the base of the shell 15 and under the cover 2.

The housing 1, the membrane unit 6, the cover 2 are fastened with bolts 11 through gaskets (not shown in Fig.). In this case, the membrane unit b sits on an elastic gasket 7 installed around the perimeter on the support pads with stiffeners 13 and 14, blocking the housing on two chambers communicating with each other only through the slots between the pockets 16. laid by strips of the turbulator 10. In the housing opposite the inlet pipe 3 mounted diffuser 12..

The membrane device operates as follows.

Partitionable mixture through pipe 3 through diffuser 12 passes through pressure channels (slots) laid by strips

turbulizer 10, uniformly flowing around the surface of the membrane 8, forming pockets 16 with drainage sheets 9 inside, into the opposite cavity, and then through

branch pipe 4 to the exit. Passed through

the membrane component of the drainage moves

to the open end of the channel into the lid cavity

2 and through the pipe 5 is discharged from the apparatus.

In case of emergency - break

membranes (see Fig. 3), a damaged pocket must be excluded from work - glue along the upper edge of the outlet of the drainage sheet 9 with glue 18 - close the leakage channel. Repair can be performed in any other way - block the channel with sealant or gasket (not shown in Fig.).
