煙氣急冷噴霧解決方案

在危廢焚燒系統中，傾入的危廢通過爐體整體轉動達到均勻混合并沿傾斜方向朝出料端移動。爐后配備二次燃燒室，垃圾在回轉窯爐內分解氣化產生可燃氣體，在二次燃燒室內達到完全燃燒。

從余熱鍋爐出來的100°- 800°高溫煙氣在急冷塔中降至200°以下或更低。急冷塔冷卻水通過霧化噴槍后，霧化成細小的顆粒與高溫煙氣充分接觸換熱，并在短時間內蒸發迅速帶走熱量，使煙氣溫度急速下降，防止二噁英在500°—300°的環境重新生成。

急冷塔采用邁德樂前端霧化AirMin噴槍可以更好的提高煙氣冷卻效率減少消耗，AirMin噴槍的三級霧化原理使其做到超細霧化,能充分與高溫煙氣充分接觸換熱,并在短時間內蒸發迅速帶走熱量,使煙氣溫度急速下降從而抑止二噁英的產生。

邁德樂前端霧化AirMin噴槍型號多樣，可根據流量范圍0.2-5.0T/h進行選擇，噴霧粒徑可達30-200μm，噴槍材質可根據具體情況進行選擇：碳化鎢TC，哈氏合金，40cr.

Gas cooling spraying solution

In the hazardous waste incineration system, the dumped hazardous waste is mixed uniformly by the overall rotation of the furnace and moves in an inclined direction towards the discharge end. The furnace is equipped with a secondary combustion chamber, where the waste is decomposed and gasified in the rotary kiln to produce combustible gases, which are completely burned in the secondary combustion chamber.

The 100°- 800° high temperature flue gas from the waste heat boiler is reduced to less than 200° or lower in the rapid cooling tower. After passing through the atomizing lance, the cooling water is atomized into fine particles which are in full contact with the high temperature flue gas for heat exchange and evaporate in a short time to quickly take away the heat, causing the flue gas temperature to drop rapidly and preventing the re-generation of dioxins at 500°-300°.

The three-stage atomization principle of the AirMin lance makes it possible to achieve ultra-fine atomization, which is in full contact with the high temperature flue gas, and evaporates in a short time to quickly take away the heat, causing the flue gas temperature to drop rapidly and thus suppressing the production of dioxins.

The AirMin front-end atomization guns are available in a wide range of models, depending on the flow rate of 0.2-5.0 T/h, with a spray particle size of 30-200 μm and in the following materials: tungsten carbide TC, Hastelloy, 40cr.
