Problems solved by technology

The centralized treatment of hazardous waste in my country mainly adopts the rotary kiln incineration process. In the current hazardous waste treatment system, most of the ash after incineration in the rotary kiln is cooled by water cooling. This method consumes a lot of water and consumes a lot of energy. High water content, large landfill volume

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the examples, the purpose is only to better understand the contents of the present invention, therefore, the examples given do not limit the protection scope of the present invention.

[0019] see figure 1 , figure 2 , image 3 , Figure 4 , including upper casing 1, lower casing 2, material guide plate 3, bracket 4, conveying device 5, stirring rod 6, cooling plate 7, cooling air inlet pipe 8, hydraulic cylinder 9, crushing device 10, connecting rod 11 .

[0020] A material guide plate 3 is installed at the feeding place of the upper shell 1 to guide the material entering the cooling device. The heat insulation material is laid on the cooling plate to reduce the corrosion of the cooling plate by high-temperature ash and slag, and at the same time prevent the high-temperature material from sticking to the cooling plate. A crushing device is installed at the outlet of the lower shell. Since t...

Abstract

The invention relates to the technical field of hazardous waste treatment, specifically to an air-cooled ash cooling device. The air-cooled ash cooling device comprises an upper shell and a lower shell; the upper shell and the lower shell are welded into a whole; a guiding plate is installed at the feeding position of the upper shell body; a crushing device is installed at the discharging position of the lower shell; a cooling air inlet pipe and a bracket are installed in the lower shell; cooling plates are installed on the bracket; conveying devices below the guiding plate are installed on the cooling plates; and stirring bars are installed on the conveying devices. According to the air-cooled ash cooling device, traditional water-cooled ash cooling is replaced with air-cooled ash cooling, the water content of ash is reduced, the landfill size is recued, structure is simple, installation is convenient, flowing of the ash can be guided, and the phenomenon that the semisolid ash is solidified and adhered to the cooling plate due to stacking on the conveying devices is avoided.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to an air-cooled ash cooling device. Background technique [0002] The disposal of hazardous waste generally involves incineration of waste and other methods of changing the physical, chemical, and biological properties of waste to achieve the purpose of reducing the amount of waste, reducing its volume, and reducing or eliminating its hazardous components. The centralized treatment of hazardous waste in my country mainly adopts the rotary kiln incineration process. In the current hazardous waste treatment system, most of the ash after incineration in the rotary kiln is cooled by water cooling. This method consumes a lot of water and consumes a lot of energy. High water content, large landfill volume. Contents of the invention [0003] The present invention aims to solve the above problems, thereby providing an air-cooled ash cooling device that reduces the water...
