Abstract

The invention discloses a device for reducing the ignition loss rate of incineration residues of a hazardous waste incineration rotary kiln. The device comprises the hazardous waste incineration rotary kiln, a special carbon residue incineration rotary kiln and a secondary combustion chamber, and the hazardous waste incineration rotary kiln and the special carbon residue incineration rotary kiln have the same structure and each comprise a feeding cover, an inner chamber, a supporting device, a transmission device and a discharging cover, wherein the inner chamber is supported on the supportingdevice, the transmission device drives the inner chamber to rotate, the feeding cover is arranged at the feeding port end of the inner chamber in a sleeving manner, and the discharging cover is arranged at the discharging port end of the inner chamber in a sleeving manner. The discharging cover of the hazardous waste incineration rotary kiln is communicated with the feeding cover of the special carbon residue incineration rotary kiln through a feeding chute; and the discharging covers of the hazardous waste incineration rotary kiln and the special carbon residue incineration rotary kiln are provided with flue gas outlets, and the flue gas outlets of the discharging covers of the hazardous waste incineration rotary kiln and the special carbon residue incineration rotary kiln are communicated with a flue gas inlet of the secondary combustion chamber through flue gas channels. The device is high in waste disposal adaptability, the incineration removal rate is larger than 99.99%, and theslag ignition loss rate is smaller than 5%.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to a device for reducing the loss-on-ignition rate of incineration residue in a rotary kiln for incinerating hazardous waste. Background technique [0002] With the development of social economy and urbanization, the amount of chemical and pharmaceutical hazardous waste is increasing. Hazardous waste is basically incinerated and safely landfilled. The rotary kiln is a common device for incineration. Its working principle is that hazardous waste is fed from the cold end of the kiln. Since the kiln has a 2.5%-4.5% inclination degree, and constantly rotate, so that the hazardous waste continuously moves to the hot end. The fuel is injected from the heating end, and it burns under the air-assisted combustion to release heat and generate high-temperature flue gas. Driven by the fan, the hot air flows from the heating end to the secondary end, and the residence time of ...
