NOZZLE ASSEMBLY Russian patent published in 2006 - IPC B05B1/12 

FIELD: gas-and-liquid mixture dispersion for different fields, particularly for air sterilization and so on.

SUBSTANCE: nozzle assembly has main nozzles connected one to another in air-tight manner and having throat areas of not less than that of the first main nozzle in gas or liquid or gas-and-liquid mixture flow direction. At least one additional nozzle is installed upstream of the first main nozzle and connected thereto in airtight manner. Additional nozzle has throat area of not less than that of the first main one. The nozzle assembly provides intensive liquid fraction film breakage and instantaneous evaporation thereof in vibro-wave cavitational space along with repeated instantaneous condensation and evaporation thereof, which results in gas-and-liquid mixture conversion into stable highly-dispersed product flow. Instantaneous evaporation and cavitational vibrations lead to pathogenous microorganism shell damage, which provides nozzle assembly usage for air sterilization. Highly-dispersed product inside the nozzle is accelerated up to supersonic velocity so that kinetic energy may be used in different fields, for instance in polishing, ground shifting, jet-stream and other fields. Above combination of bypass pipeline, ejectors, compressors and vacuum pumps may form multistage nozzle system, which provides supplying of raw oil in cavitation and vacuum boiling regimes for large distances and provides cold cracking process in which large molecules are broken into small ones to increase amount and percentage of light-weight fractions and benzene obtained from raw oil unit during following processing thereof in rectification column. Cracking operation in nozzle assembly or in several nozzle assemblies is intensified by oil heating in heat-exchanger and vapor passage via manifold. In the case of compressor usage gas may be supplied for large distances when nozzle assemblies are repeatedly activated, wherein the nozzles of the assemblies may have small differences in throat areas, wherein above differences are compensated by bypass pipeline. The nozzle assemblies connected one to another for loop forming may create cold cracking plant with technological capability control in wide range. Cavitational liquid evaporation may be improved by additional nozzle and nozzle assembly usage and liquid energy conversion into kinetic energy results in chemical bonds breakage in large liquid molecules and physical bonds damage in films and shells to impart additional energy to accelerating flow.

EFFECT: possibility to obtain highly-dispersed gas-and-liquid mixture and extended field of application.
