Device and method for disposing multiple kinds of waste synergistically in cement kiln

Abstract

The invention discloses a device and method for disposing multiple kinds of waste synergistically in a cement kiln. The device for disposing the multiple kinds of waste synergistically in the cement kiln comprises a furnace body. A feeding port and an air inlet are formed in the top of the furnace body. A slag discharging port is formed in the bottom of the furnace body. A feeding wind-locking machine is arranged in the position of the feeding port. A wind-locking valve set is arranged at the slag discharging port. A number of spraying nozzles and a number of incineration platforms in a horizontal state are arranged in the furnace body. The incineration platforms are distributed in staggered layers in the furnace body. Each incineration platform is provided with a sweeping mechanism and aflow-aiding mechanism. The cleaning mechanisms are used for pushing waste on the incineration platforms to be out and fall to next-layer incineration platforms. The flow-aiding mechanisms are used forscattering waste on the incineration platforms. The device further comprises a cement kiln decomposition furnace. A flue gas discharging port is formed in the lower portion of the furnace body. The flue gas discharging port communicates with a flue gas receiving port of the cement kiln decomposition furnace. The tertiary air outlet of the cement kiln decomposition kiln communicates with the air inlet of the furnace body. By means of the device for disposing the multiple kinds of waste synergistically in the cement kiln, combustion sufficiency and efficiency of the waste can be improved, and meanwhile, the cement quality is not influenced.

Description

technical field [0001] The invention relates to the technical field of cement kiln cooperative disposal of solid waste, in particular to a device and method for cement kiln cooperative disposal of various wastes. Background technique [0002] Solid waste refers to solid, semi-solid and gaseous articles, substances and legal, Articles and substances included in waste management as stipulated by administrative regulations. Liquid wastes that cannot be discharged into water bodies and gaseous substances that cannot be discharged into the atmosphere are generally classified into the solid waste management system due to their greater hazards. [0003] Cement kiln disposal of hazardous waste technology has been adopted in developed countries such as the United States, Canada, Japan and other countries as early as the 1970s. The research and development of the technology of using cement rotary kiln to incinerate hazardous waste in my country started in the early 1990s. There have ...
