活性炭吸附脫附催化燃燒裝置簡介 

Brief Introduction of Catalytic Combustion Device for Adsorption and Desorptionof Activated Carbon

 

一、簡介

Brife Introduction

活性炭吸附、脫附+催化燃燒是我公司自主研發的新一代VOCs處理設備,是將吸附濃縮單元和熱氧化單元有機地結合起來的一種方法,主要適用于較低濃度有機氣體且不宜采用直接燃燒或催化燃燒法和吸附回收法處理的有機廢氣,尤其對大風量的處理場合,均可獲得滿意的經濟效果和社會效果。經吸附凈化并脫附后轉換成小風量、高濃度的有機廢氣,對其進行熱氧化處理,并將有機物燃燒釋放的熱量有效利用。

 Activated carbon adsorption& desorption and catalytic combustion is a new generation of VOCs treatment equipment independently developed by our company. It is a method that organically combines adsorption concentration unit and thermal oxidation unit. It is mainly suitable for low concentration organic gases, and it is not suitable to treat organic waste gases by direct combustion or catalytic combustion method and adsorption recovery method. Especially in the case of large air volume treatment, it can be obtained. Satisfactory economic and social effects. After adsorption, purification and desorption, it is converted into organic waste gas with low air volume and high concentration, which is treated by thermal oxidation, and the heat released from combustion of organic matter is effectively utilized.

二、工作原理

Working principle

   有機廢氣先通過干式過濾,將廢氣中顆粒狀污染物截留去除,然后進入吸附床進行吸附,利用具有大比表面積的蜂窩狀活性炭將有機溶劑吸附在活性炭表面,經處理后的潔凈氣體經過風機、煙囪高空排放。

Organic waste gas is first filtered by dry filter, and the particulate pollutants in the waste gas are intercepted and removed. Then, the organic solvent is adsorbed on the surface of activated carbon by using honeycomb activated carbon with large specific surface area. The treated clean gas is discharged at high altitude through fans and chimneys.

    活性炭經過吸附運行一段時間后達到飽和,啟動系統的脫附-催化燃燒過程,通過熱氣流將原來已經吸附在活性炭表面的有機溶劑脫附出來,并經過催化燃燒反應轉化生成CO2和水蒸氣等無害物質,并放出熱量,反應產生的熱量經過熱交換部分回用到脫附加熱氣流中,當脫附達到一定程度時放熱跟脫附加熱達到平衡,系統在不外加熱量的情況下完成脫附再生過程。

Activated carbon saturates after a period of adsorption operation, starting the desorption-catalytic combustion process of the system, desorbing the organic solvents previously adsorbed on the surface of activated carbon by hot air flow, and transforming them into harmless substances such as CO2 and water vapor through catalytic combustion reaction, and releasing heat. The heat generated by the reaction is reused to the desorption additional hot air flow through the heat exchange part. When the desorption reaches a certain degree, the exothermic heat is balanced with the additional heat, and the desorption regeneration process can be completed without any additional heat
