Abstract

The invention provides a sludge drying and waste incineration co-processing device and method. The co-processing device comprises a sludge feeding hopper which is arranged at the upper part of the co-processing device and is used for receiving a sludge incoming material, a rotary kiln, a multi-stage flue, a garbage feeding hopper and a garbage incinerator. One end of the rotary kiln is connected with the sludge feeding hopper, the other end of the rotary kiln is in butt joint with a last-stage flue of the multi-stage flue, and the rotary kiln is used for heating and drying the sludge by utilizing part of flue gas of the last-stage flue of the multi-stage flue; according to the multi-stage flue, a first-stage flue in the multi-stage flue is connected with an outlet of the garbage incinerator and used for enabling flue gas generated in the garbage incinerator to sequentially pass through the multi-stage flue; the garbage feeding hopper is located on a feeding chute of the garbage incinerator and used for receiving incoming garbage; and the garbage incinerator is arranged in the middle of the co-processing device and is used for receiving the dried sludge falling into the garbage incinerator under the action of gravity and co-incinerating garbage and the dried sludge.

Description

Technical field[0001]The present invention relates to sludge drying and waste incineration, and more particularly to a sludge drying and waste incineration synergistic disposal device and method.Background technique[0002]Sludge is the product in the process of sewage treatment. As my country's industrialization process is accelerating, the production of sludge is also increased significantly, according to an aqueous rate of 80%, it is expected to reach 7,000 to 90 million tons from 2020. Sludge contains a large amount of heavy metals, pathogenic bacteria and other non-degradable and harmful substances, if there is no harmless disposal, will cause serious pollution. At present, there is only 68% of my country's sludge circumstances, and the national demand by 2020 needs to reach 90%, so the sludge is a broad market demand.[0003]Sludge is a subsequent session of sludge treatment, and sludge treatment mainly includes concentration, dehydration, drying, etc., after drying, sludge moistu...
