Creating prochnow nozzle for use fibers with a diameter of up to 10-3m, and this reduces the complexity of the nozzle Assembly inside the skeletons of volumetric elements reactors. 1 C.p. f-crystals, 1 Il.

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

Know the use of fibrous attachments in the form of bundles of fibers for mass transfer, bioreaction processes [1], in which the fibers are made of glass, nylon or polyester, as well as ion-exchange, impregnated or modified by the deposition of fibers.

However, in detail the consolidation of these fibers in space, in the amount of bioreaction devices are not tested, operating experience was not, therefore, to conclude that their strength and rigidity, the nozzle during operation impossible.

The most similar in design, mass transfer and flow characteristics of the nozzle is [2], made in the form of regular fixed on the fibrous skeleton of the cylindrical elements of b is I in the radial direction by a multitude of strands of fibrous elements on the screw surfaces and two rows, divided in the middle by the Central cord, and the middle of each of the segments of the fibers are pressed from a set of fibers with wetted and non-wetted surfaces per unit length of the element and of different diameters peripheral cords to the Central cord and two sides from it to the corresponding fibers of the other 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 per unit length of the element and of different diameters.

However, such nozzle during operation in the bioreactor installations stretches under its own weight and the weight of wet biomass held by the microorganisms, and at the breakage of the core spontaneously spins, losing fiber. Twisted polymer fibers have limited tensile strength, which does not allow to use devices with large linear dimensions, as well as to increase the diameter of the cylinder nozzle more than 80 mm

The purpose of the invention is the increased strength and rigidity, the exception stretching of the core nozzle during operation, increasing the cylinder diameter of the nozzle element.

Achieved given a Central cord of the first layer peripheral cords of woven polymer fibers and the second layer over the first peripheral cords from non-corroding cast metal wire with a resistance of metal deformation 180 MPa [3].

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 fibres of different surface and diameter.

In the proposed device the nozzle a Central cord of non-corroding cast metal wire provides a slight stretching of the core nozzle with a significant longitudinal tensile force that is very important when placing the nozzle in buildings with large linear dimensions. Pinched segments of fibrous elements to the Central cord of the first core polymer woven peripheral cords, and over them are peripheral cords from non-corroding cast metal wire provides the crushing strength and ductility of the wire at the level of the metal's resistance to deformation of not more than 180 MPa ensures the irreversibility of crushing even when the breakage of the core. In addition, the presence of three wires in the core gives it rigidity, greater tensile strength, can reduce the durability of the container, which is fixed on dosti core significantly, almost in 2 times, to increase the cylinder diameter nozzle for use fibers with a diameter of up to 10-3m, and this reduces the complexity of the nozzle Assembly inside the skeletons of volumetric elements reactors.
