Abstract

The invention discloses a system and treatment method for sludge incineration and exhaust gas treatment. The system disclosed by the invention is of a rational structure and mainly comprises an incineration furnace, a high-temperature cyclone dust collector, an air preheater, a waste heat boiler, an electric dust collector, a cloth bag dust collector and a washing tower. The system has the beneficial effects that connecting relations are more rational; pollutants generated during the exhaust gas treatment can be removed; thorough harmless treatment can be conducted on dried sludge; waste heat of exhaust gas generated after the incineration can be utilized, and secondary pollutants in the exhaust gas can be removed, so pollutant-free discharge is realized and environment-friendly effects are better; the incineration is conducted at a temperature over 850 DEG C, dioxin substances can be completely destroyed and organic compounds of such type with high toxicity do not exist during the incineration, so environment-friendly standards are satisfied better; and through combined use of the high-temperature cyclone dust collector and the washing tower, ash content particles in the exhaust gas can be reduced at an outlet, and discharge standards can be satisfied.

Description

technical field [0001] The invention relates to the technical field of sludge incineration and flue gas treatment, in particular to a sludge incineration and flue gas treatment system and treatment method. Background technique [0002] Sludge incineration is a process of sludge treatment. It uses an incinerator to heat and dry the dewatered sludge, and then uses high temperature to oxidize the organic matter in the sludge to make the sludge a small amount of ash. [0003] In the process of traditional sludge incineration and flue gas treatment, pollutants, dust, and even highly toxic organic compounds are easily produced, which will have a serious impact on the surrounding environment. Therefore, an improved technology is urgently needed to solve the problems in the existing technology. This problem exists. Contents of the invention [0004] The purpose of the present invention is to provide a sludge incineration and flue gas treatment system and treatment method. The in...
