RTO陶瓷蓄热体在燃烧炉中会爆发什么作用？

RTO装置中对热交换起到要害作用的是蓄热填充物，也称蓄热体，常用陶瓷质料做成。

在陶瓷蓄热体方面，目前在RTO中经常使用的基本上照旧陶瓷散堆填料和陶瓷规整填料两大类。在散堆填料方面：起初接纳化工中常用瓷球 和陶瓷锯鞍环，用的较多的是陶瓷矩鞍环。

现代陶瓷矩鞍环在开口面积和气流通道设计上有很大革新，从而进一步避免了填料的相叠和降低气流通过填料床层时的压力损失。

从目前RTO设备技术的进一步生长来看，首先是减少排放，就要求改善燃烧器的设计和燃烧历程，特别是对燃烧温度的控制，以及接纳电加热来替代油/气燃料，借以制止添加辅助燃料燃烧和高温可能引起的二次污染;其次是研究如何提高气速？⑿矢叩男钊忍謇此跣∽爸玫娜莼，借以降低投资用度;革新气体的初始漫衍来提高蓄热体的有效利用率和传热效果;革新切换阀来延长其使用寿命。进一步开发装置中诸参数的自动检测控制，为了提高操作的宁静性和可靠性，另有许多值得研究的问题。别的，RTO设备的数值盘算和盘算机模拟可用于理解历程的操作行为和优化设备的设计，并在某些方面可替代RTO的中间试验来节省用度。

RTO处理技术适用于高浓度有机废气、涂装废气、恶臭废气(废气浓度在500mg/L以上)等废气净化处理;适用于废气身分经常爆发变革或废气中含有使催化剂中毒或活性衰退的身分(如水银，锡，锌等的金属蒸汽和磷、磷化物，砷等，容易使催化剂失去活性
；含卤素和大宗的水蒸气的情形)，含有卤素碳氢化合物及其它具腐化性的有机气体。催化燃烧(RCO)虽然相比蓄热式燃烧(RTO)处理技术具有一定技术优势，可是RCO不适用于含金属蒸汽及卤素的废气，因为容易引起催化剂中毒。

从目前RTO装置技术的进一步生长看，RTO蓄热式燃烧炉势必成为一种新的有机废气、涂装废气、恶臭废气等废气净化处理行业的第1选择。

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.
