Incineration mode based on temperature of kiln head of rotary kiln

Abstract

The invention provides an incineration mode based on a temperature of a kiln head of a rotary kiln, and belongs to the technical field of rotary kiln waste treatment. The incineration mode comprises the following steps of storing the waste required to be treated in a stock workshop at intervals according to different types and characteristics; observing the temperature of the kiln head of the rotary kiln through a display screen; taking the waste with different types and different characteristics from the stock workshop in certain proportion according to the temperature of the kiln head, mixing the waste, grabbing the mixture through a grabbing bucket and feeding the mixture into the kiln head of the rotary kiln through a feeding machine; enabling the waste to pass through a drying section, a combustion section and a burning section to form furnace slag, and discharging the furnace slag out of the kiln; and calculating the reduction rate of the generated furnace slag through a weight reducing situation. In the mode, the combustion rate of the waste of the rotary kiln can be improved, so that the reduction rate of ash residue is qualified.

Description

technical field [0001] The invention belongs to the technical field of rotary kiln waste treatment, and more specifically relates to an incineration method based on the temperature of a rotary kiln head. Background technique [0002] Hazardous waste refers to solid waste or liquid waste that has one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity or infectivity, and may cause harmful effects on the environment or human health. Waste that needs to be managed as hazardous waste, and the treatment of this part of waste cannot be treated the same as general domestic waste. The technology of using rotary kiln incineration to treat hazardous waste, as one of the main technologies for domestic hazardous waste treatment, is being used more and more. The more extensive, but no matter which method has strict requirements on the discharge of hazardous waste after disposal, in addition to the strict control of SO2, NOX, CO, dust, blackness, et...

AI Technical Summary

Problems solved by technology

Good operation can perfectly achieve qualified flue gas emission and ash reduction rate, while bad operation will not only increase the cost, but also face fines or even shut down if the emission exceeds the standard.

If the control is not good, it is easy to cause hazardous waste to leave the rotary kiln before reaching the burnout stage, resulting in unqualified slag reduction rate

In addition, if the high temperature for a long time will increase the damage to the refractory material of the kiln head and shorten the service life
