Incineration sludge treatment process and equipment thereof

Abstract

The invention relates to an incineration sludge treatment process and equipment thereof. The incineration sludge treatment equipment comprises an incinerator and a leftover material feeding structure,one end of the incinerator is in communication with a rotary kiln, the other end of the rotary kiln is in communication with a secondary combustion chamber, the side, away from the rotary kiln, of the outer wall of the incinerator is in communication with the leftover material feeding structure, and a hot-blast stove is arranged in the middle of the inner side of the incinerator. According to theincineration sludge treatment process and the equipment thereof, waste gas generated by a drying system and the like is guided into the hot blast stove, the rotary kiln and the secondary combustion chamber through a fan to be sufficiently combusted, so that effective oxygen supply is provided, and the waste gas is reduced. Through a waste heat recovery system, the environment can be effectively protected, and the equipment is provided with the leftover material combustion system, so that secondary pollution is reduced in the production process of the whole sludge combustion process.

Description

technical field [0001] The invention relates to the technical field of incineration sludge treatment technology, in particular to an incineration sludge treatment process and equipment thereof. Background technique [0002] Sludge treatment is the process of thickening, regulating, dehydrating, stabilizing, drying or incinerating sludge. There are many methods that can be used to treat oily sludge. Chemical and physical methods such as incineration, chlorine oxidation, ozone oxidation and combustion, biological treatment methods such as bioremediation, traditional composting, etc. With the development of technology, low-temperature cold treatment and bioremediation of oily sludge have become two effective treatment methods. After drying, the dried sludge is sent to the sludge incinerator for incineration through the feeding screw in front of the furnace. Industrial solid waste Combustion in the hot blast stove, the flue gas passes through the hot blast stove and directly e...
