The invention relates to a device for mass transfer, bioreaction and hemorheology processes and can be used for cleaning gases, natural and waste waters, as well as obtaining biosynthetic products in the medical, microbiological and other industries, and utilities.

Know the use of fibrous attachments in the form of bundles of fibers for mass transfer, bioreaction and filtration processes [1].

However, such nozzle during operation stretches under its own weight and the weight of wet biomass or sorbed mechanical impurities, when the breakage of the core cords being drawn fiber is not revealed to the desired ratio of modified additives in the fiber catalysts and hard fiber twine or bristle ready-made ruff, which does not allow to use the device for conducting targeted bioreaction and hemorheology of gas cleaning processes, natural and waste waters.

The most similar in design, strength, mass transfer and flow characteristics of the nozzle is [2], made in the form of regular fixed on the frame, fibrous, cylindrical elements of infinite length, comprising a core consisting of twisted between a separate cords, with divergent about is him in the radial direction by a multitude of strands of fibrous elements, screw surfaces and two rows, separated in the middle by the Central cord, and the middle of each of the segments of the fibers pressed peripheral cords to the Central cord and two sides from it to the corresponding fibers of another series with the formation of the triple bend in the middle of staple fibres between the cords of fibrous elements consist of a set of fibers with wetted and non-wetted surfaces on the unit length of the element and of different diameters, while the Central cord and two peripheral cord consist of non-corroding cast of the wire, and at least two peripheral cords consist of a twisted yarn, non-corroding cast metal wire has a resistance to deformation of not more than 180 MPa.

However, attempts at twisting the modified catalysts of a mixture of oxides pereimenovannyh metal fibers did not succeed, as modified fibers in the triple bend and fixation on the Central metal cord break off. Each catalytic fiber must be protected from large bends in the regeneration and pulling out of the water pillar of nylon or Dacron fiber scaffold or bristle, triple bend should be more smooth, but strong enough.

The task of the invention is to increase the reactivity of the nozzle due to the inclusion in the composition of the fibers of the catalysts and the conclusion of breaking fragile catalytic fibers in the operation.

The tasks are solved by performing the Central cord of the core of polymeric filaments with a diameter at least twice larger diameter than the diameter of the catalytic fibers wound over the Central cord of the first layer peripheral cords of woven polymer fibers and the second layer over the first peripheral cords of non-corroding cast metal wire with a resistance of metal deformation 180 MPa, by placing the nozzle of a mixture of catalytic fibers of the scaffold or bristle diameter of more than 0.2 mm in a ratio of not more than 1:2, allowing you to have every catalytic fiber in four directions prop from a rigid polymer fiber scaffold or bristle above diameter.

The drawing shows the nozzle in the form of a cylinder having a core 1 comprising a Central cord 2, peripheral cords 3 of woven polymer fibers and peripheral cords 4 of non-corroding cast metal wires, and pieces of fibrous elements 5 sets of fibers of different composition and diameter.

In the proposed device the presence of a peripheral metal cords provides sufficient strength and low stretch core nozzle in substantial longitudinal stretching efforts. Pinched segments of the fibers to the Central polymeric cord core is metallic cords on top peripheral cords of woven polymer fiber provides gentle pressure conditions of catalytic fibers to the Central cord, and a Central cord at least twice larger diameter than the diameter of the catalytic fibers, ensures gentle conditions triple bend catalytic fibers and keeps it from breaking when wrapped in the ruff. Twice the fiber content of a scaffold or bristle diameter not less than 0.2 mm in the nozzle relative to the number of catalytic fibers makes it possible to surround each catalytic fiber on all four sides of the scaffold fibers or bristles and pulling the nozzle out of the water to maintain the shape of the brush, to exclude large sagging and breaking fragile catalytic fibers. In the drawing the squares are catalytic fibers, and circles - fiber scaffold. The number of catalytic fibers in the ruff can be found by the formula Nto=1+3·n, and fiber scaffold Nl=4+5·n. When n=100; Nto=301, a Nl=504. For any value of nl>Ntonot less than 2 times.

Since the total number of fibers Nl+Ntocan be written as Nto+2Ntoi.e. 3Ntothen out of the total number of fibers 3Ntonot less than 2/3 of the fibers of the scaffold and not more than 1/3 will be fiber catalytic.

The purpose of the minimum diameter of the line, equal to 0.2 mm, due to the rigidity of the scaffold and technical needs maintenance forms ruff during operation of the mass transfer reactors, focusing on the magnitude of the diameter of the brush 120 mm
