在实践中,每种废气处理方法都有自己的优点,催化焚烧设备更适合连续排放废气,如果间歇排放废气,不仅每次预热都需要消耗能量,反应热量无法回收,会造成大量的能源浪费。对于本身在废气温度较高的漆包线、绝缘材料、烘干的烤漆等废气,温度可达300℃以上,无需设置预热设备。
In practice, each waste gas treatment method has its own advantages. Catalytic incineration equipment is 美高梅游戏官网网站 suitable for continuous emission of waste gas. If the waste gas is discharged intermittently, not only every preheating need to consume energy, but also the reaction heat can not be recovered, which will cause a lot of energy waste. For the exhaust gas such as enameled wire, insulating material and baking varnish with higher exhaust temperature, the temperature can reach above 300 C, without setting preheating equipment.

In practice, each waste gas treatment method has its own advantages. Catalytic incineration equipment is 美高梅游戏官网网站 suitable for continuous emission of waste gas. If the exhaust gas is discharged intermittently, each preheating only needs to absorb energy, and the reaction heat can not be dissolved and utilized, which will cause a great waste of energy.

催化焚烧的机器设备,该设备广泛应用于各种工况的使用环境,从催化焚烧是一个典型的气-固相催化反应,它借助催化剂降低了反应的活化能,在低点火温度200 ~ 300℃下无焰燃烧,发生在固体催化剂表面氧化有机物,同时二氧化碳和水,并释放大量的热量,由于其低温氧化反应,所以极大地抑制了氮气氮氧化物在空气中高温的形成。由于催化剂的选择性催化作用,有可能限制燃料中含氮化合物(RNH)的氧化过程,使其中大部分形成分子氮(N2)。
Catalytic incineration is a typical gas-solid catalytic reaction. It uses catalysts to reduce the activation energy of the reaction. It burns flamelessly at low ignition temperatures of 200-300 degrees C. It occurs on the surface of solid catalysts to oxidize organic compounds, carbon dioxide and water, and releases a lot of heat due to its low temperature oxidation reaction. Therefore, the formation of nitrogen oxides at high temperature in air is greatly inhibited. Because of the selective catalysis of catalysts, it is possible to limit the oxidation process of nitrogen compounds (RNH) in fuels, and make most of them form molecular nitrogen (N2).

催化焚烧炉设备,该设备广泛,适用于各种工况。“气体催化焚烧”是一种典型的气固催化反应。它降低了反应的活化能有催化剂的帮助下,顶级服务这火焰——免费的焚烧以更低的点火温度200 - 300度。有机物氧化反应发生在固体催化剂的表面,而CO2和H2O发生发生,释放出大量的热量。由于其氧化反应温度较低,空气中N2的含量大大抑制了其生成高温NO 2。此外,由于催化剂的选择性催化作用,燃料中氮的氧化过程可能受到限制,大部分形成分子氮(N2)。
Catalytic incinerator equipment, which is widely used in various working conditions. Gas-catalyzed incineration is a typical gas-solid catalytic reaction. It reduces the activation energy of the reaction with the help of catalysts, and serves the flame at a top level - free incineration at a lower ignition temperature of 200 - 300 degrees. The oxidation of organic compounds occurs on the surface of solid catalysts, while CO2 and H2O occur, releasing a large amount of heat. Because of its low oxidation temperature, the content of N 2 in air greatly inhibits the formation of high temperature NO 2. In addition, due to the selective catalysis of catalysts, the oxidation process of nitrogen in fuels may be limited, most of which form molecular nitrogen (N2).
