Problems solved by technology

The kiln skin material used in this method is relatively simple, lacking elements such as aluminum, iron, calcium, etc., and the firmness and anti-stripping effect of the kiln skin are lacking
Moreover, the outlet temperature of the rotary kiln formed by the kiln skin is too low, which cannot meet the actual operation conditions when the temperature of hazardous waste incineration and disposal is higher than 1000 ° C, resulting in the melting and falling off of the kiln skin

Abstract

The invention relates to a hazardous waste treatment method, in particular to a method for establishing a hazardous waste incineration rotary kiln skin, and belongs to the technical field of hazardous waste disposal. The method includes the following preparation steps: ① The kiln skin material composition is crushed to less than 15cm×15cm×15cm, and mixed fully; %; ③ Put the materials that meet the requirements of step ② into the materials required for building the kiln skin in a small amount and multiple times according to the hourly design processing capacity of the rotary kiln; ④ Wait for the molten material in the furnace to flow to the tail of the rotary kiln After the sections are merged into a solid state, the next batch of materials will be continuously and stably put into the next batch of materials at a rate of 5% to 10% of the designed hourly processing capacity of the rotary kiln until the materials are melted and adhered to the first half of the rotary kiln, and the establishment of the kiln skin is completed. .

Description

technical field [0001] The invention relates to a hazardous waste treatment method, in particular to a method for establishing a hazardous waste incineration rotary kiln skin, and belongs to the technical field of hazardous waste disposal. Background technique [0002] Rotary kiln incinerator is an internationally recognized and widely used hazardous waste incinerator type, with mature methods and feasible technology. The furnace body of a rotary kiln is usually a steel drum lined with refractory material, and the main axis of the drum is slightly inclined in the direction of waste movement. [0003] In the process of rotary kiln incineration and disposal of hazardous waste, the service life of refractory materials directly affects the safe operation cycle of the rotary kiln system, especially the service life of refractory bricks in the kiln. The establishment of the kiln skin is to protect the refractory bricks, so that the kiln bricks are not directly in contact with the...
