陶瓷蓄熱體 - 蓄熱性能下降的緣由

蓄熱體是一個(gè)關(guān)鍵部件。但從實(shí)際應(yīng)用來(lái)看，陶瓷蓄熱體壽命往往不盡人意，原因是多方面的。陶瓷蓄熱體蓄熱性能下降表現(xiàn)在以下方面：?1.破損。煙氣與空氣對(duì)蓄熱體反復(fù)沖刷，導(dǎo)致福建陶瓷蓄熱體的溫度出現(xiàn)頻繁變化，對(duì)于蓄熱箱中某一點(diǎn)來(lái)講，其溫度要周期性地快速升高和降低100—200℃，這種熱沖擊對(duì)蓄熱體材料有一定的破壞作用。其耐急冷急熱性能往往不好，容易出現(xiàn)破損現(xiàn)象。?2.燒損。多室（兩室）蓄熱式加熱爐中，由于空氣和天燃?xì)獾膰娮旌艽螅諝狻⑻烊細(xì)鈿饬骰旌闲Ч焕硐耄瑫?huì)導(dǎo)致不完全燃燒。當(dāng)殘存的空氣和天燃?xì)膺M(jìn)入蓄熱體狹小的空間內(nèi)混合，導(dǎo)致二次燃燒從而損壞蓄熱體。?3.熔化軟化。因煙氣中含有氧化鐵等雜質(zhì)，不斷與蓄熱體接觸，在燃燒室高溫條件下，形成低熱熔物，降低材料的軟熔溫度。后面造成軟熔材料堵塞氣流通道，造成氣流不通。蓄熱體是一個(gè)關(guān)鍵部件。但從實(shí)際應(yīng)用來(lái)看，陶瓷蓄熱體壽命往往不盡人意，原因是多方面的。陶瓷蓄熱體蓄熱性能下降表現(xiàn)在以下方面： ? 1.破損。煙氣與空氣對(duì)蓄熱體反復(fù)沖刷，導(dǎo)致福建陶瓷蓄熱體的溫度出現(xiàn)頻繁變化，對(duì)于蓄熱箱中某一點(diǎn)來(lái)講，其溫度要周期性地快速升高和降低100—200℃，這種熱沖擊對(duì)蓄熱體材料有一定的破壞作用。其耐急冷急熱性能往往不好，容易出現(xiàn)破損現(xiàn)象。 ? 2.燒損。多室（兩室）蓄熱式加熱爐中，由于空氣和天燃?xì)獾膰娮旌艽螅諝狻⑻烊細(xì)鈿饬骰旌闲Ч焕硐耄瑫?huì)導(dǎo)致不完全燃燒。當(dāng)殘存的空氣和天燃?xì)膺M(jìn)入蓄熱體狹小的空間內(nèi)混合，導(dǎo)致二次燃燒從而損壞蓄熱體。 ? 3.熔化軟化。因煙氣中含有氧化鐵等雜質(zhì)，不斷與蓄熱體接觸，在燃燒室高溫條件下，形成低熱熔物，降低材料的軟熔溫度。后面造成軟熔材料堵塞氣流通道，造成氣流不通。 ? The regenerator is a key component. However, from the practical point of view, the life of ceramic regenerators is often unsatisfactory, for a variety of reasons. The thermal storage performance of ceramic regenerators is reduced in the following aspects: ? 1. Damaged. Flue gas and air repeatedly wash the regenerator, causing frequent changes in the temperature of the Fujian ceramic regenerator. For a certain point in the regenerator, the temperature should be periodically increased and lowered 100-200 °C periodically. The thermal shock has a certain destructive effect on the heat storage material. Its resistance to quenching and rapid heat is often poor, and it is prone to breakage. ? 2. Burning. In a multi-chamber (two-chamber) regenerative heating furnace, due to the large nozzles of air and natural gas, the mixing effect of air and natural gas airflow is not ideal, resulting in incomplete combustion. When the remaining air and natural gas enter the space where the regenerator is narrow, the secondary combustion causes secondary combustion to damage the regenerator. ? 3. Melt and soften. Because the flue gas contains impurities such as iron oxide, it continuously contacts the regenerator, and under the high temperature condition of the combustion chamber, a low hot melt is formed to lower the reflow temperature of the material. The back causes the reflow material to block the airflow path, causing the airflow to fail.

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.

Three kinds of commonly used fillers for environmental protection, do you only know the saddle ring packing? Look slowly, look more useful and harmless! ? 1. Step ring packing The step ring packing is an improvement to the Pall ring. Compared to the Pall ring, the step ring height is halved and a tapered flange is added at one end. ? As the aspect ratio decreases, the average path of gas around the outer wall of the packing is greatly reduced, thereby reducing the resistance of the gas through the packing layer. The tapered flange not only increases the mechanical strength of the packing, but also causes the main contact between the packing and the point contact, which not only increases the gap between the packings, but also becomes the collection and dispersion point of the liquid flow. Filler surface. It can promote the surface renewal of the liquid film and help to improve the mass transfer efficiency. ? The overall performance of the step ring is better than the Pall ring. But no saddle ring packing is easy to use. ? 2, the saddle ring packing The saddle ring packing changes the curved surface at both ends of the arc saddle packing into a rectangular surface, and the sizes of the two sides are different, that is, the saddle ring packing. ? The saddle ring packing does not stack when stacked, and the liquid distribution is relatively uniform. The saddle ring packing is generally made of porcelain material and its performance is better than that of the Raschig ring. It is an excellent one of the annular fillers used. ? 3, metal ring moment saddle filler The annular saddle filler (known locally as Intalox) is a new type of filler with annular and saddle structure features. The filler is usually made of metal, so it is also called metal ring saddle filler. ? The annular saddle packing combines the advantages of an annular packing and a saddle packing. Its overall performance is superior to the Pall ring and step ring, which is widely used in bulk packaging. But no saddle ring packing is easy to use.
