在线正规赌博,光氧催化设备焚烧管理技能
Management of incineration of photo catalytic equipment
焚烧技能即利用VOC简单焚烧的性质,将其在足够高的温度.过量空气.高温湍流的条件下,焚烧生成COz和H2O 等,主要包含直接焚烧和催化焚烧。
Incineration technology is to use the nature of VOC simple incineration, in sufficient high temperature, excess air, high temperature turbulence conditions, incineration to produce COz and H2O, mainly including direct incineration and catalytic incineration.
1.直接焚烧技能
1. direct incineration skills
直接焚烧技能依据热量的回收方式,可分为直接焚烧法和蓄热焚烧法。直接焚烧法行将有机废气加热到必定温度下(800℃左右),使其完全氧 化分 解,生成COz和H2O 等。蓄热焚烧法行将焚烧尾气中的热量积蓄,用于加热待处理废气,节能作用显着,此办法的去除功率可达99%以上,但焚烧不完全时简单发作氮氧 化物,形成二次污染,该法适用于轿车.家电等烤漆职业高温文高浓度的有机废气管理。
Direct burning technology can be divided into direct incineration method and regenerative combustion method according to the way of heat recovery. Direct incineration heating organic waste gas to a certain temperature (about 800 C), so that it completely oxidized decomposition, the formation of COz and H2O. The method of regenerative incineration is to accumulate the heat in the tail gas of incineration and use it to heat the waste gas to be treated. The energy-saving effect is remarkable. The removal power of this method can reach more than 99%. However, when the incineration is incomplete, the nitrogen oxides occur simply and form secondary pollution. This method is suitable for the management of the organic waste gas with high temperature and high concentration in the paint-baking occupations such as cars and household appliances. .
2.催化焚烧技能
2. catalytic incineration skills
催化焚烧技能经过在焚烧系统中添加催化剂,使可燃性的VOC在催化剂外表发作非均相氧 化反响,于300一500℃左右将VOC催化氧 化分 解为COz和HzO等。催化焚烧较热力焚烧温度低,能够明显下降设备运行费用,但当废气中含有能够引起催化剂中毒的硫.卤素有机化合物时,不宜选用催化焚烧法。
Catalytic incineration skills through the addition of catalysts in the incineration system, so that combustible VOC on the catalyst surface of a heterogeneous oxidation reaction, the catalytic oxidation of VOC decomposed into COz and Hz O at about 300-500 C. Catalytic incineration is lower than thermal incineration, which can obviously reduce the operating cost of the equipment. However, when the exhaust gas contains sulfur and halogen organic compounds which can cause catalyst poisoning, catalytic incineration is not suitable.

3.光催化降解技能
3. photocatalytic degradation skills
光催化降解技能在特定电磁波的紫外光照射下,发作氧 化力极强的自由基。当空气旋流进入滤网,即进入光催化反响腔时,自由基与有机蒸发气体直接进行化学反响,将其氧 化.分 解为CO2和H2O等。
The ability of photocatalytic degradation is attacked by ultraviolet light from specific electromagnetic waves, which produces free radicals that are highly oxidizing. When the air swirls into the filter, that is, into the photocatalytic reaction chamber, the free radicals react directly with the organic vapor gas to oxidize and decompose it into CO2 and H2O.
光催化的净化速率取决于所运用的催化剂和光源的功能,现在运用的催化剂主要为TiO2光催化剂。紫外光光源对VOC的净化作用较佳,如185,254,365nm波长的紫外光,尤其在苯系物的净化中,短波紫外光(如185,254nm)更具优胜。理论上,光催化氧 化进程能够将污染物完全降解为COz和H2O等无毒物质,但反响速率慢.光子功率低一级缺陷限制了其在实践中的使用。在对多组分VOC废气进行降解时,不完全的反响会发作醛.酮.酸和酷等中心产品,形成二次污染。
The purification rate of photocatalysis depends on the function of the catalyst and the light source, and the photocatalyst used now is mainly TiO2 photocatalyst. UV light source has better purification effect on VOC, such as 185, 254, 365 nm ultraviolet light, especially in benzene series purification, short wave ultraviolet light (such as 185, 254 nm) is more superior. Theoretically, the photocatalytic oxidation process can completely degrade the pollutants into non-toxic substances such as COz and H2O, but the reaction rate is slow. Low photon power first-order defects limit its application in practice. When the multi-component VOC waste gas is degraded, the incomplete reaction will produce aldehyde, ketone, acid and cool and other central products, resulting in secondary pollution.
