Embodiment Construction

[0029] Such as figure 1 As shown, the hazardous waste rotary fluidized cold slag three-stage incinerator includes rotary kiln 1, rotary kiln motor 2, cooling fan 3, fluidized slag cold device 4, three combustion chamber 5, emergency discharge door 6, quench tower 7, The upper end of the fluidized slag cooling device 4 is provided with a three-combustion chamber 5. The top of the three-combustion chamber 5 is connected with an emergency discharge door 6 and a quench tower 7. The lower side wall of the three-combustion chamber 5 is connected with the tail of the rotary kiln 1, and the tail of the rotary kiln 1 There is a cooling fan 3, and the rotary kiln 1 is equipped with a rotary kiln motor 2.

[0030] The hazardous waste enters the first combustion chamber of the rotary kiln through the hazardous waste feed port, and the first combustion chamber is rotated by the main drive motor at a specific speed. The air used for incineration is sucked from the hazardous waste warehouse by ...

Abstract

The invention discloses a hazardous waste rotary type fluidizing cold slag three-stage incinerator, including a rotary kiln, a rotary kiln motor, a cooling fan, a fluidizing cold slag device, a three-burning chamber, an emergent discharge door, a quench tower, wherein the upper end of the fluidizing cold slag device is provided with a three-burning chamber, the top of which is connected with an emergent discharge door, a quench tower, the lower side of the three-burning chamber is connected with the tail of the rotary kiln provided with a cooling fan, and the rotary kiln is provided with a rotary kiln motor. The invention can process the hazardous waste of all forms, can burn the waste of liquid, solid and sludge etc., and has low requirement on the pretreatment. Under the rotation of the fluidizing cold slag device, the slag is further crashed, the slag heat loss ratio after burning is smaller than 3%; the thrice burning chamber further strengthens the burning, which makes the failure rate of the dioxin reach 99.99%, the temperature of the smoke from the three-burning chamber to the quench tower is reduced from 1100 degrees to 200 degrees.

Description

Technical field [0001] The invention relates to a waste incineration treatment device, in particular to a hazardous waste rotary fluidized cold slag three-stage incinerator. Background technique [0002] Hazardous waste, also known as hazardous waste, is called Hazardous Waste in English. It is a type of waste with physical, chemical or biological hazards that require special management and disposal processes to avoid health hazards or other harmful effects on the environment. [0003] According to the "Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Solid Wastes", hazardous wastes are listed in the "National Directory of Hazardous Wastes" (promulgated by the State Environmental Protection Administration, the State Economic and Trade Commission, the Ministry of Foreign Trade and Economic Cooperation and the Ministry of Public Security on January 4, 1998) Or wastes identified as hazardous according to the hazardous waste identifica...
