Sludge incineration treatment system

Abstract

The invention relates to a sludge incineration treatment system which comprises a sludge purification treatment device, a gas-liquid separation device, a tail gas purification device, a drying device, a blower and an induced draft fan. The sludge incineration treatment system is characterized in that the drying device and the tail gas purification device respectively comprise an inner layer and an outer layer, smoke generated by the sludge purification treatment device enters the outer layer of the drying device, so as to indirectly dry sludge, and the smoke which enters the outer layer of the drying device enters the outer layer of the tail gas purification device from an outlet of the outer layer of the drying device; hot air generated by the sludge purification treatment device enters the inner layer of the tail gas purification device for preheating, preheated air enters the inner layer of the drying device from an outlet of the inner layer of the tail gas purification device, so as to directly dry the sludge, and the preheated air enters the gas-liquid separation device from an outlet of the inner layer of the drying device and is blown in the sludge purification treatment device by the blower for burning.

Description

technical field [0001] The invention relates to the field of garbage treatment equipment, in particular to a sludge incineration treatment system. Background technique [0002] With the progress of social economy and the increasing population of cities, urban sewage treatment, as an important environmental protection facility in cities, has been paid more and more attention. Urban sewage treatment plants have become an important means to solve water pollution, but the sludge produced by urban sewage treatment plants has also become a major public hazard that affects the city's appearance and environment. After sewage is treated, 0.5% to 1% of its volume will be transformed into The solid aggregates settle down, which is commonly referred to as sludge. Sludge disposal is a more difficult subject than sewage. The random stacking and discharge of a large amount of untreated sludge has caused new pollution to the environment, and its treatment and disposal costs are usually eq...
