一、沸石转轮+RTO(蓄热式氧化器)工艺:
1、 Zeolite Wheel+RTO (Regenerative Oxidizer) Process:
是一种的VOCs(挥发性有机化合物)废气处理技术,特别适用于处理大风量、中低浓度的有机废气。这套工艺结合了沸石转轮的浓缩能力和RTO的氧化分解能力,实现了减排和经济运行的目标。
It is an efficient VOCs (volatile organic compound) waste gas treatment technology, particularly suitable for treating high air volume, low to medium concentration organic waste gas. This process combines the concentration capacity of zeolite rotors with the oxidative decomposition capacity of RTO, achieving the goals of energy conservation, emission reduction, and economic operation.
沸石转轮吸附浓缩:
Zeolite rotary adsorption concentration:
沸石转轮是一种旋转式的吸附装置,其核心是由沸石分子筛组成的蜂窝状结构。沸石具有高度的亲水性和选择性吸附能力,能够从废气中捕捉并浓缩VOCs。沸石转轮分为三个区域:吸附区、解吸(再生)区和冷却区。
Zeolite wheel is a rotary adsorption device, with a honeycomb structure composed of zeolite molecular sieves at its core. Zeolite has high hydrophilicity and selective adsorption ability, which can capture and concentrate VOCs from exhaust gas. The zeolite wheel is divided into three zones: adsorption zone, desorption (regeneration) zone, and cooling zone.
1. 吸附区:低浓度的有机废气通过沸石转轮的吸附区时,VOCs被沸石分子筛吸附,净化后的气体直接排放。
1. Adsorption zone: When low concentration organic waste gas passes through the adsorption zone of the zeolite wheel, VOCs are adsorbed by the zeolite molecular sieve, and the purified gas is directly discharged.
2. 解吸(再生)区:沸石转轮旋转到解吸区域时,使用高温空气(通常180-220°C)对沸石进行加热,使吸附的VOCs脱附出来,形成高浓度的VOCs蒸汽。
2. Desorption (regeneration) zone: When the zeolite wheel rotates to the desorption zone, high-temperature air (usually 180-220 ° C) is used to heat the zeolite, causing the adsorbed VOCs to desorb and form high concentration VOCs vapor.
3. 冷却区:脱附后的沸石通过冷却区恢复吸附能力,准备再次吸附废气中的VOCs。
3. Cooling zone: The desorbed zeolite recovers its adsorption capacity through the cooling zone and is ready to adsorb VOCs in the exhaust gas again.
RTO蓄热式氧化:
RTO Regenerative Oxidation:
RTO是一种的氧化处理设备,用于将浓缩后的高浓度VOCs氧化分解为二氧化碳和水。其特点是利用蓄热体储存和释放热量,大幅减少能源消耗。
RTO is an efficient oxidation treatment equipment used to oxidize and decompose concentrated high concentration VOCs into carbon dioxide and water. Its characteristic is the use of thermal storage to store and release heat, significantly reducing energy consumption.
1. 蓄热氧化:浓缩后的VOCs蒸汽被送入RTO,通过蓄热体预热,然后在高温(760-950°C)条件下,VOCs被氧化分解。
1. Thermal storage oxidation: The concentrated VOCs vapor is sent to RTO, preheated by a thermal storage body, and then under high temperature (760-950 ° C) conditions, VOCs are oxidized and decomposed.
2. 热回收:RTO中的蓄热体能够吸收废气燃烧产生的热量,并在下一循环中预热进入的废气,大大减少了燃料的消耗。
2. Heat recovery: The thermal storage body in RTO can absorb the heat generated by the combustion of exhaust gas and preheat the incoming exhaust gas in the next cycle, greatly reducing fuel consumption.
沸石转轮+RTO工艺的优势在于,沸石转轮可以将低浓度的大风量废气浓缩,降低RTO处理的气量和能耗,使得整个系统更加经济。同时,RTO的热回收机制也进一步降低了运行成本。
The advantage of the zeolite wheel+RTO process is that the zeolite wheel can concentrate low concentration high-volume exhaust gas, reduce the gas volume and energy consumption of RTO treatment, and make the entire system more economical and efficient. Meanwhile, the heat recovery mechanism of RTO further reduces operating costs.
