SPARK ARRESTOR, FLAME ARRESTOR, CONDENSER WITH NOZZLES FOR REGENERATION (IPK 1.1) Russian patent published in 2018 - IPC A62C4/00 

FIELD: ventilation.

SUBSTANCE: invention relates to equipment intended to prevent propagation of a fire in industrial communications, trapping solvent vapors in ventilation systems, trapping solid aerosol particles in ventilation systems in paint workshops of metallurgical, refractory, construction, machine building, woodworking, oil producing, oil refining and other industries, as well as in the ventilation emissions cleaning environmental-friendly processes. Sparks, solvent vapors, solid aerosol particles trapping and flame localization in ventilation systems device, including metal housing with the gas-and-vapor flow inlet and outlet side branch pipes, alternating sections of filled with coolant vertical and coiled metal tubes, tube connected to the refrigerant supply sections, metal container at the device upper part with a waste coolant disposal tube, horizontally installed fine mesh grating in the housing lower part for the solid particles trapping, five nozzles on each side wall and four nozzles on the top for the solvent spraying and the tubes cleaning of the colorful aerosol, a tube for the solvent vapors condensate removing.

EFFECT: device allows to carry out combined protection against possible sources of ignition and combustion products, increase the device service life by cleaning the tubes of the colorful aerosol, reduce the device aerodynamic drag.
