Large-size hazardous waste rotary kiln type incinerator device taking sludge as main target

Abstract

The invention discloses a large-size hazardous waste rotary kiln type incinerator device taking sludge as a main target. The device comprises a receiver bin, a feeder, a multifunctional fuel nozzle, a kiln internal hot blast blowing unit, a rotary kiln, a power suspension unit, a secondary combustion chamber and a scraper slag discharging machine. The feeder, the multifunctional fuel nozzle and the kiln internal hot blast blowing unit are arranged at an inlet of the rotary kiln. The receiver bin is arranged above the feeder. The power suspension unit is arranged in the middle of the rotary kiln. The secondary combustion chamber is arranged at the tail of the rotary kiln. The scraper slag discharging machine is arranged at the lower end of the secondary combustion chamber. Three fuels, namely the solid fuel, the gas fuel, and the liquid fuel can be simultaneously or independently used for providing heat for the incinerator, and steam or nitrogen or water can be used for cooling the fiery furnace under the emergent incinerator shutdown condition. The power suspension unit and the kiln internal hot blast blowing unit are used for increasing the contact area of materials and the gas, so that the heat transferring, drying and combusting effects are improved, and the disposal capacity and efficiency of the kiln type incinerator device are improved.

Description

technical field [0001] The invention relates to the field of garbage and hazardous waste incineration treatment, in particular to the technical field of solid semi-solid garbage and hazardous waste rotary kiln type incinerator. Background technique [0002] At present, the hazardous waste rotary kiln incinerator mainly composed of sludge has not yet formed a large scale, and the incineration capacity of a single set is only dozens of tons per day. The incineration process of the waste rotary kiln incinerator is very difficult, and there is no operation example so far. How to realize the efficient incineration process of drying, incinerating and burning out the solid hazardous waste in the rotary kiln is the key to its technology. A large-scale hazardous waste rotary kiln type incinerator device based on sludge of the present invention solves such problems. Contents of the invention [0003] The purpose of the present invention is to provide a large-scale hazardous waste r...
