Abstract

The invention discloses a sludge incineration and carbonization cooperative treatment system. According to the sludge incineration and carbonization cooperative treatment system, a sludge drying device is used for drying sludge; sludge dried by the sludge drying device is introduced into an incinerator through a sludge inlet through a sludge conveying and feeding device, an auxiliary fuel inlet isused for adding an auxiliary fuel, air is introduced into the incinerator through an air inlet to be incinerated with the sludge, and smoke generated by incineration is exhausted from an air outlet.The sludge dried by the sludge drying device is introduced into a carbonization furnace to be carbonized, high-temperature flue gas is introduced into a jacket of the carbonization furnace to heat thecarbonization furnace, and high-temperature combustible gas and combustible liquid generated by pyrolysis of the carbonization furnace are recycled back into the incinerator through the air inlet tobe incinerated; an air outlet of a waste heat boiler and a flue gas outlet of a sludge carbonization furnace jacket are connected with a flue gas treatment device, after treatment in the flue gas treatment device, a product is guided into a chimney by an induced draft fan to be discharged. Through sludge incineration and carbonization cooperative treatment, the application way of a sludge heat treatment product can be expanded, and the carbonization hot flue gas treatment link is simplified.

Description

technical field [0001] The invention relates to a system for synergistic treatment of sludge incineration and carbonization, which belongs to the field of solid waste treatment. Background technique [0002] In recent years, with the rapid development of my country's economy and the acceleration of urbanization, the amount of urban sewage treatment and the corresponding amount of sludge generated in my country have grown rapidly. At the same time, with the development of the economy to a higher level and the continuous improvement of people's living standards, the requirements for environmental protection are getting higher and higher. The previous situation of heavy water and light mud has been greatly changed, and the requirements for sludge treatment are increasing and attention is increasing. . [0003] The thermal treatment technology based on sludge incineration has the advantages of killing viruses, eliminating harmful organic substances, and completely reducing volu...
