AUTOMATED POWER TECHNOLOGICAL COMPLEX FOR DEEP PROCESSING AND RECYCLING OF UNSORTED SOLID DOMESTIC AND INDUSTRIAL WASTES Russian patent published in 2020 - IPC F23G5/24 B09B3/00 C10J3/00 

FIELD: waste processing and disposal.

SUBSTANCE: invention relates to the field of solid domestic and industrial waste (SDIW) of current receipt in high-temperature furnaces of mine type. Complex comprises at least one vertical high-temperature shaft furnace, means for feeding into its upper part wastes with additives of lime, fluxes, solid fuel, means for supplying hot air (blow) to the lower part of the shaft furnace, facilities for removal of blast furnace gas, liquid slag and metal removal from furnace for production of target products, power plant for power generation and facilities for complex control, according to invention there are automated lines for preparation of charge, slag and metal processing, cleaning of waste gases, preparation of blowing and unit for automatic control of operation of said lines and shaft furnace, geometric parameters of working volume of which in conditions of processing wastes with low average density are characterized by ratio of height of furnace to average diameter of shaft (opening) 3–5.5, upper diameter (throat) to average shaft diameter of 0.7–1, and shaft average diameter to shaft furnace (hearth) bottom diameter of 1.2–1.8, line for automated charge preparation includes facilities for transportation of wastes to serially connected four sections – acceptance, dimensional cutting of wastes in dimensions of 0.2–0.6 m, separation of wastes into mineral and organo-containing components, pressing of the latter at pressure of 0.1–0.6 MPa in said dimensions and three additional sections for adding lime, fluxes and solid fuel additives into wastes to obtain charge of specified composition and its automatic layer-by-layer loading into furnace throat section by output commands of automatic control unit of lines and shaft furnace operation with possibility of its tightness preservation by exhaust gases and taking into account data on current results of measurements of temperature pulsations and flow rates of incoming and outgoing from furnace said components, outputs of regenerative heaters line of blowing for heating air or air enriched with oxygen, or air mixtures with the addition of liquid or pulverized fuel are connected through distribution units with blowing tuyeres, located belts in the hearth area and shaft furnace, part of tuyere belts is equipped with facilities for stabilization of shaft furnace operation modes by output commands of automatic control unit by means of additional controlled supply independently or together with blowing of required amount of solid or liquid fuel, lime, fluxes or wastes, mainly in pulverized or liquid form, means for heating regenerative heaters of blowing line are made with possibility of using various types of liquid or gaseous fuel, including furnace gas, cleaning line of combustible gases leaving the shaft furnace is equipped with at least one cyclone, wet and dry bag filters, an electric filter and a recuperative heat exchanger, wherein at least one bubbler and recuperative heat exchanger are arranged between the regenerative heaters outlet and the stack; line for slag and metal processing into target product includes means for periodic output by signals of automatic control unit to independently located areas of their dispensing into molds for further cooling, cleaning and storage, said and additional sources of excess heat are equipped with means for heating purposes, and power plant is configured to be converted to consumption of solid, liquid and / or gaseous types of fuel to provide for own needs or transmission of generated power to external consumer in accordance with operating conditions of shaft furnace according to automatic control unit.

EFFECT: technical result is higher efficiency, broader functional capabilities.
