AI Technical Summary

Technical Problem

Existing tunnel kilns suffer from problems such as low collection efficiency, pipe blockage, insufficient utilization of waste heat, and high energy consumption during high-temperature carbonization VOC treatment. Traditional VOC treatment methods pose environmental and energy efficiency challenges.

Method used

The system design adopts kiln self-heating source heating, VOC in-situ high-temperature oxidation, and waste heat cascade ventilation. A sealed air curtain is formed by an air curtain fan, and the VOC collection main pipe is closely attached to the outer wall of the kiln for heating. The high-temperature section radiant heat is used to prevent VOC condensation. The VOC tail gas is completely oxidized in the high-temperature area. The waste heat cascade utilization prioritizes the rapid cooling of low-temperature tail gas, and the heat recovery fan recovers the heat.

Benefits of technology

It solves the problem of VOC condensation and wall blockage, realizes fuel-free VOC treatment, significantly reduces operating costs, improves waste heat utilization, reduces system energy consumption by 20%-30%, and achieves environmentally compliant emissions.

Abstract

本发明公开了一种隧道窑高温碳化VOC治理与通风系统,沿物料行进方向依次设置升温段、高温段和降温段;窑头设置气幕风机形成密封气幕;升温段两侧设置VOC收集口,经VOC过风箱汇入VOC收集总管,收集总管紧贴高温段窑体外壁布置,利用窑体辐射热与传导热全程伴热,避免VOC冷凝粘壁;VOC引风机将尾气送入降温段750‑850℃区域,利用窑内自有高温环境实现无燃料原位氧化分解;降温段优先采用预热段尾气作为冷却介质,辅以急冷风机、抽热风机及热量回收装置,实现余热梯级利用。本发明彻底解决了VOC输送过程中的冷凝堵塞问题,无需外加燃料即可实现VOC高效治理,并通过余热回收显著降低系统能耗。
