Description

The invention relates to inkjet technology and can be used in water treatment and power systems for water decarbonization, as well as in water treatment and wastewater treatment systems for degassing and aerating water, fuel combustion, in the chemical and food industries for sorption and adsorption of liquids.

A multi-nozzle ejector for mixing media, consisting of radially arranged nozzles and an annular toroidal diffuser, is known (ed. St. USSR No. 1285210. CL F 04 F 5/02, 1985).

The drawbacks of the device are low weight and size parameters due to the impossibility of a dense layout solution of circular jet devices, high material consumption, disordered

fluid movement in the diffuser, low productivity.

Also known is a spray head in which the mixing chamber is made in the form of a series of cylinders of different diameters, mounted on a cone nozzle with a cylindrical nozzle and having different lengths (ed. St. USSR No. 902839. class B 05 V 1/00, 1980).

The disadvantage of the device is low productivity, high consumption of materials and low weight and size parameters, significant pressure in front of the head, the inability to simultaneously aerate the liquid.

Closest to the invention is a vacuum-ejection apparatus, comprising a cylindrical distribution chamber, a cone nozzle with a nozzle and a vacuum chamber, and stepped chambers

mixing with holes (Iikoladze G.N. Technologists of natural water purification. M, Higher School, 1987, p. 312).

The drawbacks of the device are significant overall, especially linear dimensions with poor performance, the lack of the possibility of a rational layout of a group of devices.

The aim of the invention is to increase the efficiency of absorption and desorption processes, increase productivity, reduce the overall dimensions of the apparatus and increase the manufacturability of the installation.

For this, the apparatus is provided with a housing and additional conical nozzles with nozzles and vacuum chambers, with the nozzles made slotted, the nozzles are placed along the perimeter in the walls of the distribution chamber, and the stepped mixing chambers and vacuum chambers are made arcuate and are formed by two variable-section disks with arcuate baffles between them to separate the zones of action of the nozzles, and the disks are installed in the housing with the formation of gas cavities interconnected by means of x channels and mixing chambers holes formed in the discs for imparting a mixing chamber with gas cavities.

FIG. 1 shows the proposed vacuum ejection apparatus; FIG. 2 is a view A-A of FIG. one; in fig. 3, 4 - various layouts of spray block options.

The vacuum-ejection apparatus contains a cylindrical distribution chamber 1, a tapered nozzle with a nozzle 2 and a vacuum chamber 3, and stepped mixing chambers with holes 4.

The device is equipped with a housing 5 and additional conical nozzles with nozzles 2 and vacuum chambers 3, with all the nozzles 2 are slotted, and the nozzles are placed along the perimeter in the walls of the distribution chamber 1.

The stepped mixing chambers and vacuum chambers 3 are arcuate and are formed by two variable-diameter disks 6 with arcuate partitions 7 between them for dividing the zones of action of the nozzles.

The disks 6 are installed in the housing 5 with the formation of gas cavities 8 and 9 interconnected by means of channels 10 in the partitions 7, and the holes of the mixing chambers are made in the disks for communication of the mixing chambers with the gas cavities 8 and 9, one of which is connected to the atmosphere .

Vacuum ejection apparatus operates as follows.

Gas saturated fluid passes

through the distribution chamber 1 into the cone nozzles with slit nozzles 2, after passing through which, the liquid jet enters the vacuum chambers 3. Due to

vacuum in the jet occurs volumetric boiling leading to desorption of media. At the exit from the first stage, the jet enters the second stage of a larger size, as a result of which a rarefaction zone is formed along the butt points of the stages. Under the action of this vacuum, gas is sucked through the holes 4 from the gas cavities 8, 9, etc. Thus, the jet of fluid is sequentially subjected to

the action of the rarefaction zones, where the liquid boils up and the gas is injected into the jet, causing a discontinuity in the flow. All this contributes to the intensification of desorption-adsorption

processes and spray liquid.

The invention allows to increase the capacity of the liquid by lengthening the distribution chamber 1 and fixing on it additional units.

devices, wherein the primary cavity of 8 additional blocks and the secondary cavity of the previous 9 are made in one piece; reduce gas throughput due to lower disk performance

constant cross section without holes 4; to increase the overall performance due to the possibility of a different layout of options for spray units (Fig. 3, 4). The use of arcuate mixing chambers, in contrast to the direct from the prototype, allows to reduce the overall dimensions of the installation, especially linear ones. Multiple radial instead of single radial construction increases productivity

installation, reduces the consumption of materials, since each arcuate wall is simultaneously a wall of two mixing chambers; reduces the overall dimensions of the installation, since each jet apparatus

works at a lower consumption, and therefore has a shorter length. The use of discs in the form of enclosing structures of the apparatus instead of cylindrical elements gives it the appearance of a thickened disc, in connection with which it improves the processability of installation and simplifies the layout of the apparatus with other technological equipment. The invention of the vacuum-ejection apparatus containing a cylindrical distribution chamber, a conical nozzle with a nozzle and a vacuum chamber and stepped mixing chambers with holes, which is so as to increase the efficiency of adsorption-desorption processes, increase productivity, reduce the overall dimensions of the apparatus and improving the processability of installation, it is equipped with a housing and additional conical nozzles with nozzles and vacuum chambers, while the nozzles are made with slotted nozzles mescheny on the perimeter walls of the distribution ka measures, and the stepped mixing chambers and vacuum chambers are made arcuate and are formed by two variable-section disks with arcuate partitions between them to separate the zones of action of the nozzles, the disks being mounted in the housing with the formation of gas cavities interconnected by means of channels made in the partitions, and the openings of the chambers mixing is performed in disks for communication of mixing chambers with gas cavities. one 1763035 Aa 70 YU
