SEWAGE AND WASTEWATER AND WATER SUPPLY AND DRAINAGE SLUDGE CAKE DRIER USING WASTE HEAT AND GAS

摘要

The invention to the waste water and sewerage stirred rapidly the moisture contained in the sludge cake, by direct and indirect hot-air processing system that is generated when handling dried to reduce sludge treatment cost through reduction of the sludge cake reduces the function, the recycling of the sludge cake a to provide a waste heat and waste water and sewage sludge cake drying apparatus using the waste gas so as to contribute to the sustainable retention policy through it is an object.; Waste water and sewage sludge cake drying apparatus using the waste heat and waste gas according to the present invention for achieving the above object is a belt conveyor and a sludge cake fed by the belt conveyor for moving the sludge cake dehydrated in the dehydrator in the horizontal that boiler as soon stored therein at the same time driven by the methane gas to means for drying to be evaporated to dryness by a hot air with stirring means is at the same time generating a superheated vapor (steam) or an exhaust heat gas and equipped hopper, and fixed to the pipe to the hopper and, it consists of a blower which is connected by a pipe to the boiler in sequence, electric heater, the valve, and that the sludge cake is stored within the input hopper stirring and drying characterized.
