Preparation method based on rotary kiln-type continuous distillation pyrolysis and gasification incinerator

Abstract

The invention discloses a preparation method based on a rotary kiln-type continuous distillation pyrolysis and gasification incinerator. The rotary kiln-type continuous distillation pyrolysis and gasification incinerator comprises a feeding device, a kiln body rotary device, a distillation pyrolysis and gasification device and a waste gas purification device. The feeding device is arranged on the right end of the kiln body rotary device; the distillation pyrolysis and gasification device is arranged on the left end of the kiln body rotary device; the waste gas purification device is arranged on the left end of the distillation pyrolysis and gasification device; the kiln body rotary device comprises a rotary kiln; the distillation pyrolysis and gasification device comprises a distillation gasification chamber and a secondary combustion chamber; the waste gas purification device comprises a cyclone dust collector, a waste heat boiler, a fast cooling tower, a neutralizing tower, a bag-type dust collector, an induced draft fan and a spray scrubber; and the preparation method comprises the following steps of material primary combustion, material distillation gasification, smoke primary combustion, smoke primary dust collecting, smoke heat exchange, smoke fast cooling, smoke neutralizing, smoke secondary dust collecting, smoke disacidifying, and smoke up-to-standard releasing. By adopting the preparation method, medical wastes or industrial wastes can be subjected to drying and distillation pyrolysis by utilizing high-temperature smoke; fuel is saved; emission is environment-friendly; and the management cost of an enterprise is lowered.

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
