      活性炭是常用的吸附剂,具有性能稳定、抗腐蚀等优点。由于它的疏水性,并具有非极 性表面,为疏水性和亲水性有机物的吸附剂。活活性炭比表面积和孔隙率大,吸附能力强,具有较好的机械强度、化学稳定性和热稳定性,净化效率高达95%。有机废气通过吸附装置,与活性炭接触,废气中的有机污染物被吸附在活性炭表面,从而从气流中脱离出来,达到净化效果。从活性炭吸附床排出的气流已达排放标准,空气可直接排放。

      其主要技术原理为:

      活性炭具有较大的目标化合物吸附空间,故吸附有机物气体的能力明显增大。活性炭表面化学性质可以说其本身是非极性的,但由于制造过程中处于微晶体边缘的碳原子共价键不饱和而易与其他元素(如H、O)结合成各种含氧官能团,如羟基、羧基、羰基等,以致活性炭又具有微弱的极性,并具有一定的化学和物理吸附能力。这些官能团在水中发生离解,使活性炭表面具有某些阴离子特性,极性增强。为此,活性炭不仅可以除去水中的非极性物质,还可吸附极性物质,优先吸附水中极性小的有机物,含碳越高范德华力越大,溶解度越小的脂肪酸愈易吸附,甚至微量的金属离子及其化合物。
      活性炭过滤用以脱除水中的微量污染物和对反渗透膜产生损害的游离氯。因为活性炭是一种非极性吸附剂,外观为暗黑色,粒状。主要成分碳、氧、硫、氢,具有良好的吸附性能和稳定的化学性质,可以耐强酸、强碱,能经受水浸、高温、高压作用,不易破碎。活性炭是用动植物、煤、石油及其它有机物作原料,经加热脱水、炭化、活化制成的。具有巨大的比表面积和发达的微孔,微孔直径为20~30埃。此外,活性炭的表面有大量的羟基和羧基官能团,可以对各种性质的有机物进行化学吸附、以及静电引力作用。因此,可以脱色,除臭味,脱除重金属、各种溶解性有机物、放射性元素、胶体及游离氯等。

      适用范围:

      1、电子元件生产、电池(电瓶)生产、酸洗作业车间、实验室排风、冶金、化工厂、医药生产厂、涂装车间、 食品及酿造、家具生产等。

      2、用于大风量、低浓度的废气工况或间歇作业中准备回收利用的有机溶剂工厂车间。

      工作原理

      设 备采用活性炭吸附、热气流脱附和催化燃烧三种组合工艺净化有机废气,利用活性炭多微孔及巨大的表面张力等特性将废气中的有机溶剂吸附,使所排废气得到净化 为第一工作过程;活性炭吸附饱和后,按一定浓缩比把吸附在活性炭上的有机溶剂用热气流脱出并送往催化燃烧床为第二工作过程;进入催化燃烧床的高浓度有机废 气经过进一点步加热后,在催化剂的作用下氧气分解,转化成二氧化碳和水,分解释放出的热量经高效换热器回收后用于加热进入催化燃烧床的高浓度有机废气为第 三工作过程,上述三个工作过程在运行一定时间达到平衡后,脱附、催化分解过程无需外加能源加热。

      Activated carbon is the most widely used method to treat organic waste gas at present. It has good adsorption performance to benzene waste gas. The main disadvantage is the high cost of operation, not suitable for high humidity environment. But on the current market applications, the use of activated carbon adsorption is the most commonly used.

      The most used method for activated carbon: granular activated carbon and activated carbon fiber, activated carbon particles prices cheaper, but less efficient than using activated carbon fiber relatively expensive, better.

      3.2: activated carbon fiber (ACF) characteristics

      (1) the specific surface area of activated carbon fiber is large, and the adsorption capacity is high. Because the specific surface area of the same weight fiber is nearly 100 times, the weight of the activated carbon fiber is very small, but the adsorption efficiency is very high. According to the organic gas content in waste gas treatment and other physical properties of the different adsorption efficiency in 85%? 98%, multistage adsorption process can reach 99.99%, far higher than the highest adsorption adsorption of active carbon particles and the volume rate of 88%, and the total weight is very small.

      (2) the adsorption and desorption process is short, the speed is fast, the desorption is low, and the regeneration energy consumption is low. The adsorption capacity of ACF on organic gas is several times as much as that of granular activated carbon (GAC), and it also has a good adsorption capacity for inorganic gas, and can maintain a higher adsorption desorption rate and longer service life. Such as water vapor heating 6? 10min, can be fully desorbed, good heat resistance, high temperature resistance in an inert gas in the air above 1000 DEG C, ignition temperature above 500 degrees.

      (3) shape is variable, easy to use. Because the activated carbon fiber can be made into felt type, the utility model has the advantages of convenient replacement and no harm to human body.

      (4) special ACF with special properties can be produced according to the need, which has good strength and will not cause the pollution of the two time.

      3.3: combustion method

      (1) direct combustion method

      Use oil or gas as auxiliary fuel combustion, the mixed gas is heated, the harmful substances at high temperatures is decomposed into harmless substances; the process is simple, small investment, suitable for waste gas with high concentration and small quantity, but the higher requirement on the safety technology and operation.

      (2) catalytic combustion method

      The exhaust gas heating by catalytic combustion into harmless carbon dioxide and water odor; this method has low ignition temperature, energy saving, high purification rate, convenient operation, small occupation area, high investment, suitable for high temperature or high concentration organic waste gas.

      3.4: adsorption method

      (1): direct adsorption of organic waste gas by activated carbon adsorption, purification of the rate of above 95%, simple equipment, small investment, but the frequent replacement of activated carbon, increase the loading and transportation and replacement procedures, resulting in increased operating costs.

      (2) adsorption recovery method: the use of activated carbon fiber adsorption of organic waste gas, in the vicinity of saturation after the use of hot water vapor blowing, the desorption regeneration; this law requires the necessary amount of steam.

      (3) the new adsorption desorption concentration - catalytic combustion method: the advantage of this method combines adsorption and catalytic combustion method, using novel adsorption materials (honeycomb activated carbon) adsorption, hot air into the near to the limit of desorption, desorption analysis, gas catalytic combustion bed flameless combustion, the thorough purification the use of hot gas, circulating in the system, greatly reduce the energy consumption. The method has the advantages of stable and reliable operation, low investment, low operation cost, convenient maintenance, etc. the utility model is suitable for the treatment of the waste gas with large air volume and low concentration.

      3.5: photocatalytic oxidation method

      Under UV irradiation, the air catalytic reaction, resulting in a large number of ozone, the odor of the CO oxidation decomposition reaction of the malodorous gases into the material degradation of low molecular compounds, water and carbon dioxide, so as to achieve the purpose of deodorization and killing bacteria.

      3.6: low temperature plasma method:

      1, the main use of pulsed high frequency plasma power supply and double dielectric plate discharge device, the form of high concentration of ions in the form of discharge. Plasma is a kind of aggregation material, which has the high energy electron energy in the millisecond time, instantaneous breakdown of air and waste gas molecules, a series of differentiation of cracking reaction, produce high concentration, high strength, high energy active free radicals and a variety of electronic, ionic, molecular collision with machine in exhaust gas occurs when a series of elementary physicochemical reactions, and produce a variety of active free radicals and ecological oxygen in the reaction process, atomic oxygen is produced by the decomposition of ozone. The activity of free radicals can effectively destroy the virus, nucleic acid, protein in bacteria, which can not be normal metabolism and biosynthesis, thus causing his death; but the ecological oxygen can quickly remove the organic waste gas molecule odor decomposition or reduction of harmful substances of low molecular; in addition, with the help of plasma from
