  催化燃烧设备是一种典型的气固催化反应,其本质是活性氧的深度氧化。在催化燃烧过程中,催化剂的作用是降低活化能,催化剂在表面具有吸附作用,使反应物分子在表面富集,提高反应速率,加快反应速度。
  Catalytic combustion equipment is a typical gas-solid catalytic reaction, its essence is the deep oxidation of active oxygen. In the process of catalytic combustion, the role of catalyst is to reduce the activation energy, and the catalyst has adsorption on the surface, which makes the reactant molecules accumulate on the surface, improves the reaction rate and accelerates the reaction speed.
  的帮助下催化剂,有机废气可以没有火焰条件下的燃烧点火温度低,氧化分解为二氧化碳和水,同时释放大量热能,从而达到去除废气中的有害物质的方法。
  With the help of the catalyst, the organic waste gas can be ignited at a low temperature without flame, oxidized and decomposed into carbon dioxide and water, and released a lot of heat energy at the same time, so as to achieve the method of removing harmful substances in the waste gas.
  在将催化燃烧过程中废气,废气管道通过风扇进入换热器,热气体催化燃烧点火温度需要,通过催化剂床层,让它燃烧,但由于存在催化剂,催化燃烧的点火温度250 - 300℃,远低于直接燃烧法的燃烧温度650 - 800℃,因此远低于直接燃烧法对能源消费。
  In the process of catalytic combustion, the exhaust gas enters the heat exchanger through the fan. The ignition temperature of hot gas catalytic combustion needs to pass through the catalyst bed to make it burn. However, due to the presence of catalyst, the ignition temperature of catalytic combustion is 250-300 ℃, far lower than the combustion temperature of direct combustion method of 650-800 ℃, so far lower than the energy consumption of direct combustion method.
  解吸时间和解吸周期可根据使用情况确定,一般一个碳盒解吸时间5-10小时,循环解吸时间为10-15天。吸附有机废气的活性炭床可与催化燃烧后的废气进行脱附再生,脱附后的气体可送至催化燃烧室净化。催化燃烧室采用贵金属催化剂,陶瓷蜂窝体,阻力小,活性高。当有机蒸汽浓度达到2000PPM以上时,可保持自燃,全自动控制,操作方便,维护方便。

  The desorption time and desorption cycle can be determined according to the use situation. Generally, the desorption time of a carbon box is 5-10 hours, and the cycle desorption time is 10-15 days. The activated carbon bed adsorbing organic waste gas can be desorbed and regenerated with the waste gas after catalytic combustion, and the desorbed gas can be sent to the catalytic combustion chamber for purification. Noble metal catalyst and ceramic honeycomb are used in the catalytic combustion chamber, with small resistance and high activity. When the concentration of organic steam reaches more than 2000 ppm, it can keep spontaneous combustion, fully automatic control, convenient operation and maintenance.
  吸附操作可同时或独立进行,将大风量、低浓度的有机废气浓缩成小流量、高浓度的有机废气。将浓缩的高浓度气体接入再生催化燃烧设备进行氧化处理,即对吸附材料活性炭进行再生,以恢复其吸附能力。再生操作不能同时进行,一次只能脱除一种吸附剂。
  The adsorption operation can be carried out simultaneously or independently, and the organic waste gas with large air volume and low concentration can be concentrated into the organic waste gas with small flow and high concentration. The concentrated high concentration gas is connected to the regeneration catalytic combustion equipment for oxidation treatment, i.e. the activated carbon is regenerated to restore its adsorption capacity. Regeneration cannot be carried out at the same time, only one adsorbent can be removed at a time.
  预处理后的喷漆废气由风机泵送,风道抽提。初步净化后,气体进入活性炭吸附剂。有机气体被活性炭吸收,气体被净化。
  After pretreatment, the waste gas of painting is pumped by fan and extracted by air duct. After preliminary purification, the gas enters the active carbon adsorbent. The organic gas is absorbed by the activated carbon, and the gas is purified.
  为避免二次污染,保护活性炭,各吸附单元均设有漆雾膜过滤器,对漆雾进行预处理。雾膜过滤器采用多层复合阻燃玻璃纤维,密度,厚度逐渐增加,作为配角,用一层不同的材料的多层纤维过滤拦截后,漆雾粒子碰撞、扩散、吸收,等等将漆雾粒子包含在材料,为了避免过多的漆雾粒子包含影响过滤效果,漆雾膜过滤器配有脉冲除尘装置,可定期吹灰对漆雾膜过滤器进行除尘,其工作可靠。
  In order to avoid secondary pollution and protect the activated carbon, each adsorption unit is equipped with a paint mist membrane filter to pretreat the paint mist. The fog film filter adopts multi-layer composite flame-retardant glass fiber, with the density and thickness increasing gradually. As a supporting angle, the paint mist particles are included in the material after being filtered and intercepted by a layer of multi-layer fiber of different materials, such as collision, diffusion and absorption. In order to avoid the influence of too many paint mist particles on the filtering effect, The paint mist filter is equipped with pulse dust removal device, which can blow dust regularly to remove dust from the paint mist filter, and its work is reliable.
