Abstract

The invention relates to devices for producing highly dispersed aerosols and can be used in the medical, chemical, microbiological and other industries. The aim of the invention is to expand the range of regulation of generator performance and aerosol performance. For this, the generator cover is made removable, and the tank is equipped with a reflector located at its upper end. Depending on the position of the nozzles, the mode of operation of the generator without separation with single and double separation is provided, which significantly expands the range of control of dispersion of the aerosol. 1 il.

Description

The invention relates to devices for producing highly dispersed aerosols and can be used in the medical, chemical, microbiological and other industries.

The aim of the invention is to expand the range of control of generator performance and aerosol dispersion.

The drawing shows a generator, a general view, a section.

The generator comprises a cylindrical tank 1 for liquid with a removable lid 2 having an axial outlet nozzle 3. The cover 2 is attached to the tank 1 s. using hinged bolts 4. In the lower part of the tank 1, the axial nozzle 5 is placed, which is connected with the gas supply nozzle 6. The pipe 7 is radially fixed to the pipe 7, each of which is rotatably bent at an angle of 90 ° to each of which can be rotated, mixed and fixed in position by means of a cap nut 8 a centrifugal ejection nozzle 11 is attached to the second end of the branch pipe 9, equipped with polyvinyl chloride tubes 12 connected to fittings 13 for collecting sprayed liquid. At the upper end of the tank 1, a reflector 14 is provided. The generator is mounted on a stand 15, which is fixed to the rack 17 by a nut 16. If necessary, part of the nozzles 13 is dismantled and a plug 18 is installed on the pipe 7.

The generator works as follows.

The gas from the supply source goes to the rods - the ceru 6 and, the passage through the internal channels of the rack 17, the axial nozzle 5, through the pipes 7 and the nozzles 9, goes to the nozzles II. The tangential gas injection in the vortex chamber in the nozzle 11 forms a swirling flow with a vacuum zone along the axis. Through tube 12, liquid is ejected from the bottom of tank 1 and sprayed into droplets. Chord, 1, the installation of the nozzles in the cylindrical tank 1 ensures the swirling of the gas-liquid flow, while large drops precipitate

the walls and flow down to the bottom of the generator, and the small ones are carried away with the gas flow. The thinnest aerosol in the double separation mode is discharged through the nozzle 3. When the lid 2 is removed and the nozzles are installed with the direction of the spray of the sprayed liquid on the walls or bottom of the tank, the mode of operation of the generator with a single separation is realized. The reflector 14 prevents the surface film of liquid from moaning outside the generator.

When installing the nozzles with the direction of the flares beyond the tank 1, the operation mode of the nozzles without separation is provided.

The proposed generator makes it possible to significantly expand the range of control of aerosol dispersity and generator performance.
