吸附催化燃烧,低浓度有机废气流量,温度低,使用催化燃烧需要大量的燃料消耗,可以吸附在吸附剂上的吸附有机废气的浓度,然后通过热空气净化,有机废气剥离高浓度有机废气(可以集中10倍以上),然后催化燃烧。在这一点上,你不需要添加热源来保持正常运行。
Adsorption catalytic combustion, low concentration of organic waste gas flow, low temperature, the use of catalytic combustion requires a lot of fuel consumption, can be adsorbed on the adsorbent concentration of organic waste gas, and then through hot air purification, organic waste gas stripping high concentration of organic waste gas (can concentrate more than 10 times), and then catalytic combustion. At this point, you don't need to add a heat source to keep it running.
预热是RCO催化燃烧的基本流动形式。有机废气的温度低于100℃,浓度低,热量不能自给。因此,有在进入反应器前对反应器室进行预热,使其温度升高。经过燃烧和净化,气体与未经处理的废气在热交换器中交换,以回收部分热量。这个过程通常用气体或电加热到催化反应所需的点火温度。
Preheating is the basic flow form of RCO catalytic combustion. The temperature of organic waste gas is lower than 100 ℃, the concentration is low, and the heat is not self-sufficient. Therefore, the reactor chamber is preheated before entering the reactor to increase its temperature. After combustion and purification, the gas is exchanged with the untreated waste gas in the heat exchanger to recover part of the heat. This process is usually heated by gas or electricity to the ignition temperature required for the catalytic reaction.

当有机废气的温度高于点火温度(约300℃)和有机质的含量高,产生的热换热器复苏净化气体的一部分可以保持热平衡在正常操作期间不需要补充热量。通常在催化反应器中安装电加热器来点火。
When the temperature of the organic waste gas is higher than the ignition temperature (about 300 ℃) and the content of organic matter is high, part of the recovered purified gas of the heat exchanger can be kept in heat balance, and no additional heat is needed during normal operation. An electric heater is usually installed in the catalytic reactor to ignite.
催化燃烧一般采用天然气作辅助燃料,也可用燃料油、电加热等作辅助燃料。助燃一般用净化后的气体,如果净化后的气体不能作为助燃,则应引入空气助燃。
Natural gas is generally used as auxiliary fuel for catalytic combustion, and fuel oil and electric heating can also be used as auxiliary fuel. Generally, purified gas is used for combustion supporting. If the purified gas cannot be used as combustion supporting gas, air should be introduced to assist combustion.
要使通过催化剂表面的气流和温度分布均匀,并保证火焰不直接接触催化剂表面,燃烧室必需具有足够的长度和空间。催化燃烧装置应具有良好的保温效果。炉体一般用钢结构的外壳内衬耐火材料,或用双层夹墙结构。
The combustion chamber must have enough length and space to make the air flow and temperature distribution uniform through the catalyst surface and ensure that the flame does not directly contact the catalyst surface. Catalytic combustion device should have good heat preservation effect. The furnace body is usually lined with refractory material with steel structure shell or double wall structure.
由于催化燃烧为不可逆的放热反应,所以,无论反应进行到什么阶段,都应在尽可能高的温度下进行,以获得较高的转化速度。但操作温度往往受某些条件的限制,如催化剂的耐热温度、高温材料的获得,热能的供应,以及是否伴有副反应等。因而实际生产中应根据实际情况恰当地选择。
Since catalytic combustion is an irreversible exothermic reaction, it should be carried out at the highest possible temperature no matter what stage of the reaction is, so as to obtain a higher conversion rate. However, the operating temperature is often limited by some conditions, such as the heat-resistant temperature of the catalyst, the acquisition of high-temperature materials, the supply of heat energy, and whether there are side reactions. Therefore, it should be selected according to the actual situation in actual production.
催化燃烧装置便于清洗和更换。催化剂反应器一般应设计成装卸方便的模屉结构,便于清洗和更换催化剂载体。设计催化燃烧装置要考虑这些方面。
The catalytic combustion device is easy to clean and replace. Generally, the catalyst reactor should be designed as a mold tray structure with convenient loading and unloading, so as to clean and replace the catalyst carrier. These aspects should be considered in the design of catalytic combustion device.
