pp喷淋废气净化塔是什么产品?可能很多人不是很了解,下面脱硫pp喷淋废气净化塔厂家小编为***家先容一下。
What is the product of PP spray waste gas purification tower? Maybe many people don't know it very well. Here's a brief introduction of desulfurization PP spray waste gas purification tower manufacturer.
pp喷淋废气净化塔
(1)吸取法
(1) absorption method
吸取净化法是废气治理中一种重要的常用的方法,它是利用废气中各混合组分在选定的吸取剂中溶解度的不同,或其中一种或多种组分与吸取剂中活性组分结合,将有害物从废气中分离出来、净化废气目的的一种方法。
Absorption purification is an important and commonly used method in waste gas treatment. It is a method to separate harmful substances from waste gas and purify waste gas by using the different solubility of each mixed component in the selected absorbent, or the combination of one or more components and the active component in the absorbent.
吸取法使用的吸取设备主要有喷淋洗涤器、泡沫洗涤器、文氏管洗涤器等。吸取法的工艺流程和湿法除尘工艺近似,只是湿法除尘工艺用清水,而吸取法净化有害气体要用溶剂或吸取溶液。
The absorption equipment used mainly includes spray scrubber, foam scrubber, venturi scrubber and so on. The absorption process is similar to the wet dedusting process, except that the wet dedusting process uses clear water, while the absorption process uses solvent or absorption solution to purify harmful gases.
吸取法的***点是几乎可以处理各种有害气体,适用范围很广,并可回收有价值的产品。缺点是工艺比较复杂,吸取效率有时不高,吸取液需要再次处理,否则会造成废水的污染。
The advantage of absorption method is that it can deal with almost all kinds of harmful gases, has a wide range of application, and can recover valuable products. The disadvantage is that the process is relatively complex, sometimes the absorption efficiency is not high, and the absorption solution needs to be treated again, otherwise it will cause waste water pollution.
(2)活性炭吸附法
(2) activated carbon adsorption
吸附是一种固体表面现象,是活性炭吸附塔利用多孔性固体吸附剂处理的气态污染物,使其中的一种或几种组分,在分子引力或化学键力的作用下,被吸附在固体表面,从而达到分离的目的。其中应用为广泛的是活性炭。
Adsorption is a kind of solid surface phenomenon. It is a gaseous pollutant treated by porous solid adsorbent in activated carbon adsorption tower. One or several components are adsorbed on the solid surface under the action of molecular gravity or chemical bond force, so as to achieve the purpose of separation. Among them, activated carbon is widely used.
活性炭对对苯、甲苯、二甲苯、乙醇、煤油、汽油、苯乙烯、氯乙烯等物质都有吸附功能。活性炭净化装置具有较高的效率,但活性炭吸附到   量时会达到饱和,      或   换活性炭,因此运行成本较高。活性炭吸附设备常用于低浓度废气和脱臭的后处理。
Activated carbon has adsorption function for benzene, toluene, xylene, ethanol, kerosene, gasoline, styrene, vinyl chloride and other substances. The activated carbon purification device has high efficiency, but when the amount of activated carbon is absorbed, it will reach saturation, or change the activated carbon, so the operation cost is high. Activated carbon adsorption equipment is often used in the post-treatment of low concentration waste gas and deodorization.
(3)生物除臭法
(3) biological deodorization
生物除臭法是通过微生物的生理代谢将具有臭味的物质加以转化,达到除臭的目的。目前   污水处理厂和污水泵房采用生物法处理废气的方法主要有土壤脱臭法、生物滤池法和生物滴滤塔等,治理效果较***。
Biological deodorization is to transform the substances with odor through the physiological metabolism of microorganisms, so as to achieve the purpose of deodorization. At present, the methods of biological treatment of waste gas in sewage treatment plant and sewage pump house mainly include soil deodorization, biological filter and biological trickling filter, etc. the treatment effect is good.
(4)低温等离子体技术
(4) low temperature plasma technology
等离子体是继固态、液态、气态之后的物质***四态,当外加电压达到气体的放电电压时,气体被击穿,产生包括电子、各种离子、原子和自由基在内的混合体。放电过程中虽然电子温度很高,但重粒子温度很低,整个体系呈现低温状态,所以称为低温等离子体。低温等离子体降解污染物是利用这些   电子、自由基等活性粒子和废气中的污染物作用,使污染物分子在短时间内发生分解等离子体去除污染物。该方法具有处理效果***,运行费用低廉、无二次污染、运行稳定、操作管理简便、即开即用等***点。
Plasma is the fourth state of matter after solid, liquid and gas. When the applied voltage reaches the discharge voltage of gas, the gas is broken down and a mixture of electrons, various ions, atoms and free radicals is produced. Although the electron temperature is very high, the temperature of heavy particles is very low, and the whole system presents a low temperature state, so it is called low temperature plasma. The degradation of pollutants by low-temperature plasma is to use these active particles such as electrons and free radicals and the pollutants in the exhaust gas to decompose the pollutants in a short time. The method has the advantages of good treatment effect, low operation cost, no secondary pollution, stable operation, simple operation and management, ready to use and so on.

(5)紫外光(UV)催化氧化
(5) ultraviolet (UV) catalytic oxidation
废气的UV光催化氧化装置处理机理包括两个过程:一是在产生   离子群体的过程中,   数量的有害气体分子受   作用,本身分解成单质或转化为无害物质。二是含有***量   粒子和高活性的自由基的离子群体,与分子气体(如H2S、甲苯等)作用,打开了其分子内部的化学键,转化为无害物质。新生态的氧离子具有很强的氧化性,能有效地氧化分解不受负离子作用控制的有机物。与废气反应后多余的氧离子(正),能与氧离子(负)很快结合成中性氧。
The treatment mechanism of UV photocatalytic oxidation device for waste gas includes two processes: one is that in the process of generating ion groups, a number of harmful gas molecules are affected, and they are decomposed into simple substances or transformed into harmless substances. Second, the ion group containing a large number of particles and highly active free radicals, interacts with molecular gases (such as H2S, toluene, etc.), opens the chemical bond inside its molecules, and transforms into harmless substances. The new ecological oxygen ions have strong oxidizability, which can effectively oxidize and decompose the organic matters not controlled by the negative ions. After reacting with the waste gas, the excess oxygen ions (positive) can quickly combine with oxygen ions (negative) to form neutral oxygen.
紫外光催化是常温深度反应技术。光催化氧化设备可在室温下将水、空气和土壤中有机污染物氧化成   无害的产物。
UV catalysis is a deep reaction technology at room temperature. Photocatalytic oxidation equipment can oxidize organic pollutants in water, air and soil into harmless products at room temperature.
(6)RTO(RegenerativeThermalOxidizer,简称RTO)
(6) RTO (regenerative hermaloxidizer)
RTO即   热氧化分解器,又称蓄热式焚烧器。其基本原理实在高温下(≥760℃)将有机废气氧化生成CO2和H2O,从而净化废气,并回收分解时所释出的热量,以达到环保节能的双重目的。RTO是一种用于处理中高浓度挥发性有机废气的节能型环保装置。RTO主体结构由燃烧室、陶瓷填料床和切换阀等组成。该装置中的蓄热式陶瓷填充床换热器可使热能***限度的回收,热回收率***于95%,处理VOC时不用或使用很少的燃料。若处理低浓度废气,可选装浓缩装置,以降低燃烧消耗。
RTO is a thermal oxidation decomposer, also known as a regenerative incinerator. Its basic principle is to oxidize the organic waste gas to CO2 and H2O at high temperature (≥ 760 ℃), so as to purify the waste gas and recover the heat released during decomposition, so as to achieve the dual purpose of environmental protection and energy saving. RTO is a kind of energy-saving environmental protection device which is used to treat middle and high concentration VOC waste gas. The main structure of RTO is composed of combustion chamber, ceramic packing bed and switch valve. The regenerative ceramic packed bed heat exchanger in the device can recover the heat energy to a large extent, and the heat recovery rate is more than 95%. There is little or no fuel used in VOC treatment. If low concentration waste gas is treated, concentration device can be selected to reduce combustion consumption.
RTO处理技术适用于有机废气、涂装废气、恶臭废气等废气净化处理;适用于废气成分经常发生变化或废气中含有使催化剂中毒或活性衰退的成分(如水银,锡,锌等的金属蒸汽和磷、磷化物,砷等,容易使催化剂失去活性;含卤素和***量的水蒸气的情形),含有卤素碳氢化合物及其它具有腐蚀性的有机气体。
RTO treatment technology is applicable to the purification of organic waste gas, coating waste gas, odor waste gas and other waste gas; it is applicable to the situation that the components of waste gas often change or the waste gas contains components (such as mercury, tin, zinc and other metal vapor, phosphorus, phosphide, arsenic, etc.) that make the catalyst toxic or activity decline, and it is easy to make the catalyst inactive; it contains halogen and a large amount of water vapor, containing halogen Hydrocarbons and other corrosive organic gases.
废气pp喷淋废气净化塔净化率高,净化率一般在98%以上。可实现全自动化控制,操作简单,运行稳定,   可靠性高。蓄热室内温度均匀分级增加,加强了炉内传热,换热效果   佳,炉膛容积小,降低了设备的造价。采用分级燃烧技术,延缓状燃烧下释出热能;炉内升温匀,烧
The purification rate of waste gas PP spray waste gas purification tower is high, and the purification rate is generally above 98%. It can realize full automatic control, simple operation, stable operation and high reliability. The temperature in the regenerator increases uniformly and hierarchically, which strengthens the heat transfer in the furnace, has good heat exchange effect, small furnace volume and reduces the cost of equipment. Adopt staged combustion technology to release heat energy under delayed combustion; raise the temperature in the furnace evenly and burn
