Feeding preheating bin and cement kiln waste treatment device and method thereof

Abstract

The invention discloses a feeding preheating bin and a cement kiln waste treatment device and method thereof.The conveying platform comprises a plurality of stages of step structures which are connected in the preheating direction and gradually lowered, and each step structure comprises a material bearing area used for bearing waste and an air blowing opening matched with the material bearing area; the blowing opening is communicated with an air cannon for supplying jet airflow to the blowing opening, the jet airflow passes through the blowing opening, flows in the preheating direction and pushes the waste in the material bearing area, the step structures are arranged, so that the waste can be conveyed step by step along the step structures, and the whole pile of waste is spread on the step structures; the air blowing opening is used for jetting air flow to push waste in the material bearing area, the waste is conveyed stage by stage along the step structures, the moving speed of the waste in the preheating bin body is reduced, and it is guaranteed that the waste is fully heated in the preheating bin body; and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of waste treatment, in particular to a material feeding preheating bin and a cement kiln waste treatment device and treatment method thereof. Background technique [0002] Cement kiln co-processing is a new waste disposal method proposed by the cement industry. It refers to putting solid waste that meets the requirements of entering the kiln after pretreatment into the cement kiln. The process of innocuous disposal of waste. Cement kiln waste disposal systems include SMP system, sludge system, waste liquid system, manual delivery system and other disposal systems, all of which use hazardous waste directly into the kiln tail calciner. If the amount of waste entering the kiln is too large, the There is too much waste in the calciner quickly rolling down the kiln, and too much contact between the waste and the cement raw meal will inevitably cause the instability of the parameters of the preheater system such ...

AI Technical Summary

Problems solved by technology

However, it is equipped with multi-stage preheaters, so that the waste needs to be transported to the preheaters one by one, which inevitably leads to time-consuming and laborious transportation, and makes the entire system complex and increases costs.
