Incineration method based on rotary kiln head temperature

Abstract

The invention provides an incineration method based on the temperature of the kiln head of a rotary kiln, which belongs to the technical field of waste treatment of the rotary kiln, and comprises the following steps: storing the waste to be treated at intervals in the stock workshop according to different types and properties; The temperature of the kiln head is observed through the display device; according to the temperature of the kiln head, wastes of different types and properties are mixed in a certain proportion from the storage workshop, and they are grabbed by the grab bucket and entered into the rotary kiln head through the feeder; the waste The slag is formed after the rotary kiln passes through the drying section, the burning section and the burnout section, and then exits the kiln; the reduction rate of the slag generated is calculated according to the weight loss. This method can improve the combustion rate of waste in the rotary kiln and make the ash and slag reduction rate 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, in addition to the strict control of SO2, NOX, CO, dust, blackness, etc. in the incin...

AI Technical Summary

Problems solved by technology

Good operation can perfectly achieve qualified flue gas emission and ash slag ignition rate, while bad operation will not only increase the cost, but may 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 ignition 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
