船舶行業(yè)的廢氣處理設(shè)備中，沸石轉(zhuǎn)輪RTO是一種常用的技術(shù)。這種技術(shù)主要用于處理低濃度、大風(fēng)量的有機(jī)廢氣，適用于不含有硫、氮、氯、氟等鹵素的廢氣。這些廢氣在燃燒后不會(huì)產(chǎn)生新的副產(chǎn)物。如果廢氣中含有這些成分，則需要在預(yù)處理階段將其去除。此外，廢氣的沸點(diǎn)不應(yīng)過(guò)高，例如大于300°C，因?yàn)檫@樣會(huì)導(dǎo)致吸附到沸石分子篩上的廢氣在熱空氣的吹掃下長(zhǎng)時(shí)間脫附不出來(lái)。

Zeolite rotary RTO is a commonly used technology in the exhaust gas treatment equipment of the shipbuilding industry. This technology is mainly used to treat organic waste gases with low concentration and high air volume, and is suitable for waste gases that do not contain halogens such as sulfur, nitrogen, chlorine, and fluorine. These exhaust gases will not produce new by-products after combustion. If these components are present in the exhaust gas, they need to be removed during the pretreatment stage. In addition, the boiling point of the exhaust gas should not be too high, such as greater than 300 ° C, as this will cause the exhaust gas adsorbed on the zeolite molecular sieve to be unable to desorb for a long time under the blowing of hot air.

沸石轉(zhuǎn)輪RTO廢氣處理工藝主要由沸石轉(zhuǎn)輪濃縮系統(tǒng)（包括吸附區(qū)域、脫附區(qū)域、冷卻區(qū)域）、脫附系統(tǒng)、蓄熱式氧化系統(tǒng)（包括RTO爐體、陶瓷蓄熱體、燃燒系統(tǒng)等）以及PLC控制系統(tǒng)等部分組成。其工作原理是利用沸石轉(zhuǎn)輪的轉(zhuǎn)動(dòng)，將吸附有大量VOCs的廢氣進(jìn)入高溫脫附區(qū)，利用小風(fēng)量的高溫氣體將沸石轉(zhuǎn)輪上吸附的VOCs分子脫附出來(lái)，形成高濃度廢氣。脫附后的高濃度廢氣進(jìn)入后端的廢氣氧化焚燒系統(tǒng)進(jìn)行熱氧化處理，凈化后的廢氣可達(dá)標(biāo)排放。

The zeolite rotary RTO waste gas treatment process mainly consists of a zeolite rotary concentration system (including adsorption zone, desorption zone, cooling zone), desorption system, thermal storage oxidation system (including RTO furnace body, ceramic thermal storage body, combustion system, etc.), and PLC control system. Its working principle is to use the rotation of the zeolite wheel to enter the high-temperature desorption zone with a large amount of VOCs adsorbed on the waste gas, and use a small amount of high-temperature gas to desorb the VOCs molecules adsorbed on the zeolite wheel, forming high concentration waste gas. The high concentration exhaust gas after desorption enters the exhaust gas oxidation incineration system at the back end for thermal oxidation treatment, and the purified exhaust gas can meet the emission standards.

此外，沸石轉(zhuǎn)輪RTO技術(shù)在船舶行業(yè)中也有應(yīng)用。例如，上海熱之緣環(huán)保提出的“氣改電”方案，即沸石轉(zhuǎn)輪電加熱RTO，在船舶修造業(yè)的VOCs治理中使用。這個(gè)方案創(chuàng)新地使用電能替代傳統(tǒng)燃?xì)鉃镽TO處理設(shè)備供熱，提高了安全性和節(jié)能效果。通過(guò)采用變頻、熱回收等節(jié)能技術(shù)，這種方法比傳統(tǒng)燃?xì)夤峁?jié)約25%以上的能源費(fèi)用，并降低溫室氣體排放。

In addition, zeolite rotary RTO technology has also been applied in the shipbuilding industry. For example, the "gas to electricity" plan proposed by Shanghai Re Zhi Yuan Environmental Protection, namely zeolite rotary electric heating RTO, is used in VOCs treatment in the shipbuilding industry. This solution innovatively uses electricity instead of traditional gas to provide heating for RTO processing equipment, improving safety and energy efficiency. By adopting energy-saving technologies such as frequency conversion and heat recovery, this method saves more than 25% of energy costs compared to traditional gas heating and reduces greenhouse gas emissions.
