RTO陶瓷蓄熱體在燃燒爐中會產生什么作用？

RTO裝置中對熱交換起到關鍵作用的是蓄熱填充物，也稱蓄熱體，常用陶瓷材料做成。

在陶瓷蓄熱體方面，目前在RTO中經常使用的基本上還是陶瓷散堆填料和陶瓷規整填料兩大類。在散堆填料方面：起初采用化工中常用瓷球 和陶瓷鋸鞍環，用的較多的是陶瓷矩鞍環。

現代陶瓷矩鞍環在開口面積和氣流通道設計上有很大改進，從而進一步防止了填料的相疊和降低氣流通過填料床層時的壓力損失。

從目前RTO設備技術的進一步發展來看，首先是減少排放，就要求改善燃燒器的設計和燃燒過程，特別是對燃燒溫度的控制，以及采用電加熱來替代油/氣燃料，借以避免添加輔助燃料燃燒和高溫可能引起的二次污染;其次是研究如何提高氣速。開發效率高的蓄熱體來縮小裝置的容積，借以降低投資費用;改進氣體的初始分布來提高蓄熱體的有效利用率和傳熱效果;改進切換閥來延長其使用壽命。進一步開發裝置中諸參數的自動檢測控制，為了提高操作的安全性和可靠性，還有許多值得研究的問題。此外，RTO設備的數值計算和計算機模擬可用于理解過程的操作行為和優化設備的設計，并在某些方面可替代RTO的中間試驗來節省費用。

RTO處理技術適用于高濃度有機廢氣、涂裝廢氣、惡臭廢氣(廢氣濃度在500mg/L以上)等廢氣凈化處理;適用于廢氣成分經常發生變化或廢氣中含有使催化劑中毒或活性衰退的成分(如水銀，錫，鋅等的金屬蒸汽和磷、磷化物，砷等，容易使催化劑失去活性；含鹵素和大量的水蒸氣的情形)，含有鹵素碳氫化合物及其它具腐蝕性的有機氣體。催化燃燒(RCO)雖然相比蓄熱式燃燒(RTO)處理技術具有一定技術優勢，但是RCO不適用于含金屬蒸汽及鹵素的廢氣，因為容易引起催化劑中毒。

從目前RTO裝置技術的進一步發展看，RTO蓄熱式焚燒爐勢必成為一種新的有機廢氣、涂裝廢氣、惡臭廢氣等廢氣凈化處理行業的第1選擇。

What role does RTO ceramic regenerator play in the furnace?

The key to the heat exchange in the RTO device is the heat storage filler, also known as the heat storage body, which is usually made of ceramic material.

In terms of ceramic regenerators, the two types currently used in RTO are basically ceramic bulk packing and ceramic structured packing. In the case of random packing: the porcelain ball and the ceramic saw saddle ring used in the chemical industry were originally used, and the ceramic saddle ring was used more.

Modern ceramic saddle rings have been greatly improved in opening area and airflow passage design to further prevent stacking of the packing and reduce pressure loss as the gas flows through the packed bed.

From the further development of RTO equipment technology, the first is to reduce emissions, and it is required to improve the design and combustion process of the burner, especially the control of combustion temperature, and the use of electric heating instead of oil/gas fuel to avoid adding auxiliary. Secondary pollution caused by fuel combustion and high temperature; secondly, how to increase gas velocity. Develop high-efficiency regenerators to reduce the volume of the device, thereby reducing investment costs; improving the initial distribution of gas to improve the effective utilization and heat transfer of the regenerator; and improving the switching valve to extend its service life. Further development of automatic detection and control of parameters in the device, in order to improve the safety and reliability of the operation, there are still many problems worth studying. In addition, numerical calculations and computer simulations of RTO equipment can be used to understand the operational behavior of the process and to optimize the design of the equipment, and in some respects can replace RTO intermediate tests to save money.

The RTO treatment technology is suitable for the purification of exhaust gases such as high-concentration organic waste gas, painted exhaust gas, and odorous exhaust gas (exhaust gas concentration above 500mg/L); it is suitable for the frequent changes of exhaust gas components or the components in the exhaust gas that cause catalyst poisoning or activity degradation ( Metal vapors such as mercury, tin, zinc, etc., and phosphorus, phosphide, arsenic, etc., tend to deactivate the catalyst; in the case of halogens and large amounts of water vapor, contain halogen hydrocarbons and other corrosive organic gases. Although catalytic combustion (RCO) has certain technical advantages over regenerative combustion (RTO) treatment technology, RCO is not suitable for exhaust gas containing metal vapor and halogen because it is easy to cause catalyst poisoning.

From the further development of the current RTO device technology, the RTO regenerative incinerator is bound to become the first choice for a new exhaust gas purification treatment industry such as organic waste gas, painted exhaust gas and odorous exhaust gas.
