FIRE-BASED INDUSTRIAL WASTE NEUTRALISER WITH CONTAINER REMOVAL OF MECHANICAL IMPURITIES Russian patent published in 2014 - IPC F23G7/04 

FIELD: chemistry.

SUBSTANCE: fire-based industrial waste neutraliser with container removal of mechanical impurities comprises a heat-insulated housing (1), a reservoir for the liquid to be decontaminated, made from open-top working (2) and circulating (3) containers placed in container sections (4), radiating burners (5) with an annular flat flame, placed in radiators (6), having air channels (7) and smoke channels (8) adjacent to the air channels, connected to a common gas conduit (9), connected to a smoke pipe (10), pipes for feeding the liquid (11) to be decontaminated. The fire-based neutraliser further includes a heat recovery unit (12), connected to a smoke pipe (10) mounted on it, wherein outlet gas conduits (13) of the heat recovery unit (12) are connected to the smoke pipe higher than the point of mounting a smoke gate (14), placed in the smoke pipe over the common gas conduit (9) connected to it. In the smoke pipe, higher the point of connection of outlet gas conduits (13), there is an additional atomiser (15) with co-current ascending flow of flue gases by a liquid reagent spray and a drop catcher (16) over it. The working (2) and circulating (3) containers are arranged in pairs vertically under the radiator (6) and above said radiator, respectively, in each of the container sections (4), placed on two sides of the common gas conduit (9), and each radiator (6) is capable of moving horizontally out of the container section (4). The air channels (7) of the radiators (6) are connected to the top part of each container section (4); outer end walls of the container sections (4) are provided with flap lids (17) in the bottom part and swing doors (18) in the top part. Heat-insulated removable lids (19) are placed on top of the container sections (4) to enable supply of atmospheric air into the top part of the container sections (4).

EFFECT: invention reduces specific consumption of fuel, electric power and emissions of dust particles and sulphur oxide into the atmosphere.
