Preparation method of rotary kiln type continuous carbonization pyrolysis gasification incinerator

Abstract

The rotary kiln type continuous dry distillation pyrolysis gasification incinerator includes a feeding device, a kiln body rotary device, a dry distillation pyrolysis gasification device, and a tail gas purification device. The right end of the kiln body rotary device is provided with a feeding device, the left end of the kiln body rotary device is provided with a dry distillation pyrolysis gasification device, and the left end of the dry distillation pyrolysis gasification device is provided with a tail gas purification device; the kiln body rotary device includes a rotary kiln, dry distillation pyrolysis gasification device The gasification device includes a dry distillation gasification chamber and a secondary combustion chamber, and the tail gas purification device includes a cyclone dust collector, a waste heat boiler, a quenching tower, a neutralization tower, a bag filter, an induced draft fan, and a spray washing tower; the preparation method includes the following operation steps: Initial combustion of material → dry distillation and gasification of material → initial combustion of flue gas → preliminary dust removal of flue gas → heat exchange of flue gas → quenching of flue gas → neutralization of flue gas → secondary dust removal of flue gas → acid removal of flue gas → discharge of flue gas up to standard. The invention can use high temperature flue gas to dry, dry distillation and pyrolyze medical waste or industrial waste, save fuel, discharge environmental protection and reduce the operating cost of enterprises.

Description

technical field [0001] The invention belongs to the field of energy saving and environmental protection equipment and technology, in particular to a preparation method of a rotary kiln type continuous dry distillation pyrolysis gasification incinerator, which is suitable for dry distillation, pyrolysis, gasification of medical waste or industrial waste (including hazardous waste). incineration. Background technique [0002] Existing rotary kiln equipment generally has high kiln body temperature and low combustion chamber temperature, which requires fuel or gas to support combustion, which increases the operating cost of the enterprise. [0003] The Chinese patent with the notification number CN2295914 discloses a rotary kiln type garbage incinerator, which is characterized by a circular kiln barrel, a kiln head cover, a kiln tail cover, a sealing device, a burner, an air supply port, and a smoke exhaust port. , feed inlet, ash outlet, driving device, and refractory material...

AI Technical Summary

Problems solved by technology

If this patent is adopted, there are the following technical defects: when the traditional rotary kiln processes materials such as medical waste or industrial waste (including hazardous waste), the air supply to the kiln body is not uniform, resulting in the incineration of the material inside the kiln body. To achieve the purpose of dry distillation, pyrolysis, and gasification, resulting in insufficient flue gas volume and low temperature in the combustion chamber, which cannot meet the relevant national environmental protection requirements, and then requires fuel or gas to support combustion, which directly increases the operating cost of the enterprise
