    如果待处理有机废气的温度在大约300℃以上时，是不适合采用蓄热式系统(RTO)的,这是因为高温的待处理有机废气会大大降低换向阀的可靠性和寿 命;另外，在这样高的温度时,建造RTO的高成本也不足以抵消在节省燃料和电力消耗所带来好处。如果待处理有机废气的温度超过500℃，采用热回收式焚烧 系统不如采用直燃式焚烧系统，因为在燃料消耗的差距太小，不足以抵消增加的热回收器带来的投资成本。建湖县喷漆房丨东台印刷车间废气治理

    直燃式氧化器能够处理大浓度范围的碳氢化合物，从十亿分之一的浓度水平到纯碳氢化合物蒸气。如果有机废气浓度超过25%，特别考虑要执行措施来防止从氧化器到废气来源的回火。这种能处理大浓度范围的弹性能力的代价是这种型式氧化器的高燃料成本。

    当有机废气中含有高浓度的可转化有机酸的物质(如氯，氟，硫和卤素)时必须特别小心。他们会对设备造成严重的腐蚀或令催化剂中毒。

    当有机废气中含有微小颗粒时也必须特别小心。例如，当废气中含有油雾颗粒时，它们会聚集在管道和氧化器较冷的部位，那这个设备就需要经常清理。

    可以基于上述的原则选择适合您的有机废气处理系统，如果两种或更多型式的氧化器都适合您使用，让我们为您做一个基于一次型投资成本和设备的运行成本 (催化剂、燃料和电力费用)的详细经济分析，以帮助你做出一个好的的选择。有机废气的排放流量,如果待处理有机废气的流量是在5000Nm3/h以下，蓄热式系统(RTO)大体来说是不适用的。这是因为与热回收式焚烧系统来比较，蓄热式氧化器(RTO)的高成本大体上是不足以抵消它在节省燃料和电力消耗所带来好处。

    有机废气处理洗涤塔是一种新型的气体净化处理设备。它是在可浮动填料层气体净化器的基础上改进而产生的，广泛应用于工业废气净化、除尘等方面的前处理，净化效果很好。由于其工作原理类似洗涤过程，故名洗涤塔。

    洗涤塔由塔体、塔板、再沸器和冷凝器组成。在使用过程中再沸器一般用蒸汽加热，冷凝器用循环水导热。在使用前应建立平衡，即通入较纯的产物组分用蒸汽和冷凝水调节其蒸发量和回流量，使其能在塔板上积累一定厚度液体，当混合气体组分通入时就能迅速起到洗涤作用。在使用过程中要控制好一个液位，两个温度和 两个压差等几个要点。即洗涤塔液位，气体进口温度，塔顶温度，塔间压差(洗涤塔进口压力与塔顶压力之差)，冷凝器压差(塔顶与冷凝器出口压力之差)。建湖县喷漆房丨东台印刷车间废气治理

低浓度恶臭有机废气处理

4、作用机理：

（1）复合光催化金属镍网的作用机理

??? 复合光催化泡沫金属*纳米复合技术,整合纳米光触媒材料与泡沫镍的优良特性,在泡沫镍基体上均匀负载一定量的纳米TiO2而获得的一种负载型光催化功能材料。TiO2光催化氧化是活性羟基(?OH)和其他活性氧化类物质(?O2-，?OOH ，H2O2)共同作用的结果。在TiO2表面生成的?OH基团反应活性很高，具有高于有机物中各类化学键能的反应能，加上?O2-，?OOH ，H2O2活性氧化类物质的协同作用，能迅速有效地分解有机物。

（2）森林之源干式异味控制技术机理

??? 森林之源Vaportek臭味去除技术采用由三十多种天然植物提取液制成的臭味去除剂，该植物提取液包裹在单向透析膜（世界）中使用，由于透析膜具有单向渗透作用，在将Vaportek植物提取液除臭味粒子均匀分布于膜片表面，并利用空气对流动力带出而迅速消除臭味的同时，不会吸入外在的其它物质，永葆植物提取液的天然性。

??? 进入空气中的除臭微粒子可迅速主动捕捉空气中的臭味气体分子，并将臭味粒子包裹住。而常见的臭气分子大多为小分子有机物（酯类、醇类、芳烃类等），同时也包括部分无机小分子如臭氧、氨、硫化氢、碳氢类等，它们通常在嗅觉细胞表面活性较高，刺激性较强，即使在各臭气成分浓度均达标排放的前提下，仍然具有*的嗅觉污染能力，也就是具有通常所说的低污染浓度、高臭气强度的特性。VAPORTEK粒子为天然油性脱臭分子，该粒子通过分子间非极性相互作用与臭气分子发生非共价结合，从而大大稳定该类分子，降低其活性与刺激性。进而，由于结合后比重的增加，通过沉降作用解决。此过程既不同于化学反应过程而生成第三种物质，也不同于掩盖作用，不会造成二次污染，可*去除臭味。

废气处理设备普遍应用在化工厂、电子厂、喷漆厂、汽车厂、涂料厂、石油化工行业、家具厂、食品厂、橡胶厂、塑胶厂等产生异味、臭味、有毒有害气体的行业的废气净化设备深受企业的欢迎。不过那种费用低、耗能少、无二次污染、尽量做到节约能耗，有利环保的设备是人们的。

在设备对其废气进行处理的过程中，废气通过水洗箱后，使其中的洗涤液具有酸性和含有大量杂质。如不及时地清洗这些腐蚀性物质和杂质，不仅会缩短水洗箱的寿命，而且将直接影响等设备的净化效率。因此，为了更好的保护设备，让设备更好的为我们所用，我们需要了解一下它该如何保养。

If the flow to be processed is below 5000Nm3/h, the regenerative system (RTO) is generally not applicable. This is because the high cost of the regenerative oxidizer (RTO) is generally inadequate to counteract the benefits of saving fuel and power consumption compared with the thermal incineration system. When the flow rate is greater than 50000Nm3/h, the thermal and thermal incineration system has serious economic drawbacks, because they will generate very high fuel costs. However, if a large amount of heat energy is needed in the process, a two level heat boiler can be used to offset high fuel costs, and the other is an emergency system for dealing with large flow of waste gas with little operation every year.

If the temperature of the waste gas is treated above 300 degrees centigrade, it is not suitable for the use of the regenerative system (RTO), which is because the high temperature treatment of the organic waste gas will greatly reduce the reliability and life of the reversing valve; in addition, at such a high temperature, the height of the construction of the RTO is not enough to offset the fuel and power consumption. The benefits are brought. If the temperature of the waste gas is over 500, the heat recovery incineration system is not better than the direct combustion system, because the gap between fuel consumption is too small and it is not enough to offset the investment cost of the increased heat recovery.

Direct fired oxidizer can handle hydrocarbons with the maximum concentration range from 1/1000000000 to pure hydrocarbon vapor. If organic waste gas concentration exceeds 25%, special measures should be taken to prevent tempering from oxidizer to exhaust gas source. The cost of this ability to deal with large range of elastic capacity is the high fuel cost of this type of oxidizer.

Special care must be taken when organic waste gas contains high concentration of organic acids (such as chlorine, fluorine, sulfur and halogen). They will cause serious corrosion to equipment or catalyst poisoning.

When organic waste gas contains tiny particles, special care must also be taken. For example, when the exhaust gas contains oil mist particles, they will gather in the cooler part of the pipeline and oxidizer, so the equipment needs cleaning regularly.

If two or more types of oxiders are suitable for you on the basis of the above principles, let's make a detailed economic analysis based on the cost of the primary investment and the operating cost of the equipment (catalyst, fuel, and electricity) to help you make the best choice. Choose. The discharge volume of organic waste gas, if the volume of organic waste gas to be treated is below 5000Nm3/h, the regenerative system (RTO) is generally not applicable. This is because the high cost of the regenerative oxidizer (RTO) is generally insufficient to counteract the benefits of saving fuel and power consumption compared with the heat recovery incineration system.

Organic waste gas treatment scrubber is a new type of gas purification equipment. It is produced on the basis of a floating packer gas purifier, which is widely used in the pretreatment of industrial waste gas purification, dust removal and so on. The purification effect is very good. Because its working principle is similar to the washing process, it is called scrubbing tower.

The washing tower consists of a tower body, a tray, a reboiler and a condenser. During the operation, the reboiler is usually heated by steam, and the condenser is heated by circulating water. The balance should be established before use, that is, to adjust the amount of evaporation and reflux by using steam and condensate, so that it can accumulate a certain thickness of liquid on the tray. In the course of using, we must control a liquid level, two temperature and two pressure difference and so on several main points. That is, the liquid level of the washing tower, the inlet temperature of the gas, the top temperature of the tower, the differential pressure between the towers (the difference between the inlet pressure of the washing tower and the pressure of the top of the tower), the difference of the pressure of the condenser (the difference between the top and the outlet pressure of the condenser).
