SPARK TRAP, FLAME ARRESTER, CAPACITOR (ICF 1.0) Russian patent published in 2016 - IPC A62C4/00 

FIELD: fire safety.

SUBSTANCE: invention relates to equipment intended to prevent propagation of a fire in industrial communications, in technological processes, trapping solvent vapors in ventilation systems, catching solid aerosol particles in ventilation systems in paint workshops of metallurgical, refractory, construction, machine building, wood processing, oil production, oil refining and other industries, as well as in ecological processes of cleaning ventilation emissions. Device for catching sparks, solvent vapors, solid aerosol particles and localisation of flame in ventilation systems includes a metal housing with lateral inlet and outlet pipes for gas-air flow, alternating sections of vertical and helical-coil metal tubes filled with coolant, tube attached to sections for feeding the coolant, metal vessel in the upper part of the apparatus with a tube for removal of waste coolant, horizontally mounted small-sized meshed grid in the lower part of the housing to catch solid particles and tube to remove condensate discharge of solvent vapors.

EFFECT: use of the disclosed device enables a combined protection from possible sources of ignition and combustion products, higher reliability, reduction of aerodynamic resistance of the device, lower power consumption, higher efficiency of spark trapping, higher efficiency of flame arresting, more efficient catching of aerosol particles, condensing and catching solvent vapors.
