The utility model relates to devices for the separation, purification and concentration of liquid systems with a reverse osmosis, ultrafiltration and microfiltration method and can be used in chemical, petrochemical, microbiological and other industries.

Known membrane apparatus comprising a housing, end caps with nozzles, tube sheets, tubular membrane elements and means for mounting the latter in the tube sheets, while the tube sheets are installed parallel to the axis of the housing and one of them is removable, and the means for attaching the tubular membrane elements in the form of gaskets, pressure bushings mounted on the ends of the membrane elements located on the tube sheets of the partitions with holes for accommodating the pressure bushings and threaded bushings for fixing the ends of the membrane elements in the holes of the partitions in which the mating thread for the threaded sleeves is made, while the holes of the latter are conical with a cross-sectional area increasing towards the side of the body (see US Pat. RF No. 2046007, class B 01 D 63 / 06).

The disadvantage of this device is the complexity of the design, low reliability.

A membrane module containing a pack of tubular membrane elements in the form of porous tubes with a membrane deposited on the outer surface, fixed in tube sheets and enclosed in a cylindrical housing with nozzles

supplying the liquid to be cleaned and drainage of the concentrate and permeate, while on the inner surface of the housing spherical protrusions are made, the first of which is located opposite the nozzle for supplying the liquid to be cleaned. In the module, the protrusions are made in the form of spherical segments fixed with screws on the inner surface of the housing. In the module, the porous tubes are made with flattened sections deployed relative to each other. In the module, the porous tubes are fixed in the tube sheet with flare nuts with a tapered thread. In the module, the porous tubes are fixed in the tube sheet with threaded conical bushings (see US Pat. RF No. 2050956, CL 01 D 63/06)

The disadvantage of this membrane module is the design complexity, low reliability and performance.

The closest in technical essence and the achieved positive effect and adopted by the authors for the prototype is a membrane apparatus containing two tube plates in which tubular membrane elements are fixed and fastening devices and sealing ends of the membrane elements are located, while the fastening devices are made in the form of a tapered sleeve with a slot and a corrugated inner surface and a clamping nut with an inner conical surface. Mating with the outer surface of the sleeve (see. A. S. of the USSR No. 1606165, 01 D 63/06)

The disadvantage of this membrane apparatus is the complexity of the design and assembly.

The technical result that can be achieved using the present invention is to simplify the design and facilitate its assembly.

tubular membrane elements are fixed and fastening and sealing devices for the ends of the membrane elements are located, while the fastening devices are made in the form of a mounting sleeve with a sealing gasket, the latter is fixed with a clamping nut with an external thread.

In FIG. 1.-given a general view of the membrane apparatus, section.

In figure 2. - given a pipe plate.

The membrane apparatus consists of two pipe plates 1, in which tubular membrane elements 2 are attached, a cap 3 with a fitting 4 for supplying an initial solution, a cap 5 with a fitting 6 for draining the concentrate. The tube plates 2 are equipped with a fastening device, consisting of a mounting sleeve 7, with a gasket 8, the latter is fixed by a clamping nut 9 with an external thread.

Membrane apparatus operates as follows.

Previously, before operation, the membrane apparatus is equipped with tubular membrane elements 2. Mounting sleeves 7 are mounted in the seats on the tube plates 1, into which tubular membrane elements 2 are installed. Next, sealing gaskets 8 are installed in the mounting sleeves 7, which are fixed by clamping nuts 9, which perform the functions fixing and adjusting the joint seal. The separated initial solution under pressure is supplied through the supply nozzle 4 into the cavity of the cap 3 above the tube plate 1. Then, through the channels of the clamping nut 9 and gasket 8 with the mounting sleeve 7, the solution is supplied to the membrane elements 2, where the solution is separated. The concentrate is discharged from the apparatus through the cavity of the cap 5 under the pipe plate 1 and the outlet fitting 6.

The proposed utility model for comparing with a prototype and other well-known technical solutions has the following advantages:

simplification of construction;

It does not require large expenses during assembly, repair and operation.
