APPARATUS FOR REMOVING MATERIAL ADHERED ONTO INNER PART OF EXHAUST PIPE OF SHAFT KILN

摘要

PURPOSE: An apparatus for removing the material stuck on the inner part of exhaust pipe for exhausting flue gas generated from shaft kiln for calcining limestone is provided. CONSTITUTION: The apparatus comprises a cleaning water supply pipe (125) which is penetratingly installed on the exhaust pipe, and on the end part of which injection nozzles (129,132) are mounted to inject cleaning water into the exhaust pipe; control valves (126,131a,131b) for controlling the supply amount of cleaning water supplied through the cleaning water supply pipe; and a controller (200) for controlling operation of the control valves, wherein the apparatus further comprises a manometer (122) installed in rear of the penetration part of the exhaust pipe where the cleaning water supply pipe penetrates the exhaust pipe so that the manometer measures pressure inside the exhaust pipe; a fluid supply pipe (133) penetratingly installed on the exhaust pipe so that air and cleaning water are injected along the inner circumference of the exhaust pipe; a control means for controlling the supply amount of the air and cleaning water supplied through the fluid supply pipe; and first and second thermometers (121,123) for measuring temperature of front end rear sides of the fluid supply pipe.
