INSTALLATION FOR THERMAL RECYCLING OF TAILS OF SORTING SOLID MUNICIPAL WASTES Russian patent published in 2024 - IPC F23G5/27 

FIELD: recycling solid wastes.

SUBSTANCE: invention relates to thermal treatment and recycling of solid wastes in municipal services and industry by gasification and combustion in conditions which ensure environmentally friendly composition of end products – flue gases and coke-ash residue. Installation for thermal recycling of tails of sorting solid municipal wastes comprises gasification chamber with combustible gas discharge opening, solid wastes loading opening, afterburner chamber, heating chamber with flue gas inlet and outlet branch pipes. Gasification chamber is located inside the heating chamber. In the lower part of the gasification chamber there is a grate and a comb, and under the gasification chamber there is an ash pan, primary and secondary gates, above each of which there are fixed scrapers, a screw ash remover. Ash pan with the auger ash remover is located under the grate, primary and secondary gates. Upper part of the ash pan is equipped with a primary air inlet branch pipe with an adjustable gate valve. Afterburning chamber is separated by a separate element, in the lower part of which a diesel burner is installed, a gas duct of combustible gas from the gasification chamber with a secondary air duct and a control damper are connected, in the upper part there is a gas duct with a cold air admixture branch pipe and a control flap for discharge of combustion products into the heating chamber.

EFFECT: increasing the efficiency and reliability of solid municipal waste disposal, ensuring a uniform temperature over the entire height of the gasification chamber.
