Rotary kiln for firing cement clinker using waste

摘要

The invention relates to a device for burning the cement clinker in which the terms of technology may incineration of solid combustible wastes such as used tires, low grade coal fuel, municipal solid waste, combustible waste liquid and pasty. The purpose of the invention - an increase furnace capacity, stabilization of its operation, clinker quality improvement, increase durability of the lining in the sintering zone, replace up to 20% of the basic process fuel waste. Rotary kiln for burning the cement clinker, comprising a housing and located in the zone of the calcining device is feeding solid fuel, preferably used tires, tires reflector is mounted over the output tray, the damper shaft is provided with locking mechanisms, and the length of the incoming gateway inside the furnace is 0,4-0, 7, the diameter of the furnace body, the tray bottom is designed as a roller conveyor, a reflector - in the form of a lattice with rollers mounted in parallel rollers tray lock mechanism is configured as a cam disk gravity driven roller contacting with the valve lever axis, a damper formed on the periphery of the window for air suction, the total area of ​​which amounts to 0.1-0.5 of its area, and are mounted further governing valve, to ensure the supply of additional fuel in an inflammable liquid waste calcination zone, the dispenser is formed as a spray device. In order to provide an additional supply to the low-calorie powdered fuel and / or combustible waste kuskoobraznyh captured by scrubbers in thermal power stations in the calcination zone is formed in the additional conduit inverted cone.
