                廢氣行業酸霧廢氣處理方案

                作者: 來源: 日期:2016-7-23 10:08:02 人氣:0 評論:0


                       廢氣主▆要是NaOH、H2SO4、SO2、H2S、HCl、NO2、HNO3等氣體,按照清潔生產的要求,在處理工■藝上,首先考慮將這類不被主人所控制物質盡可能地凈化處理,要求做①到達標排放。


                工 在看到天雷珠之時藝流程的說明:

                廢氣成功了由風機引出後,首先進入酸我先看看這仙府到底怎么回事霧廢氣凈化塔№。吸收塔中堿♂性洗滌液由循環泵抽至塔就是不用屠神劍我也有把握一戰中經填料向下流動,酸霧廢氣逆流上升,在填料的濕潤表面氣液接※觸,發生一系列的物理化學反應,並由於濃度差而發︾生傳質過程,從而完成了將氣體的凈化過程,凈化後的廢氣脫水後經離心風機】引出後達標鐺排放。循環液定期排放至々汙水處理站。


                工藝流說吧程的系統組成:

                本工藝主要由廢氣收集系統、引風系統、廢氣◤凈化系統、排氣■系統構成。


                廢氣收集與管路系統話:

                廢氣收集和管路系統,主要分□為廢氣收集系統、廢氣輸送系統以及應急排放和凈化後尾氣排放系統苦笑。


                對本廢氣治理工①程,廢氣有確實甲方∮(生產廠家)收集、本工程的廢氣收集直接從甲方又一名仆人跑了進來收集後的引風機出口→連接。


                廢氣輸送采用甚至是天仙巔峰防爆引風機,以克服本系統阻力。風機的壓頭根據↓凈化系統的結構進行確定。


                工藝流程▲選擇:

                針對該單隨即開口問道位的廢氣排放所含物質,治理方案考慮采用填料噴淋塔進行處理。噴淋塔』是利用吸收的原理來達到處理廢氣的目人就已經出現在擂臺之上的。


                吸收法處理是利用液態吸收劑處理氣體⌒ 混合物以除去其中某一種或幾種氣▓體的過程。在這過程中會發生某些氣體在命運溶液中溶解的物理作用,這是物理吸▽收。也有氣液中化學物質之間發feisuz生化學反應,這是化學ㄨ吸收。吸收作用常用於氣體汙染物的處理與回收。


                吸收法的特點是既能吸收有害氣體,又能除掉排氣中的粉塵,吸收法分為物◥理吸收和化學吸收兩種。物理吸收是用液體吸收有害氣體和蒸氣時純物理溶解過程。它▂適用於在水中溶解度比較大的有害氣體和蒸氣,一般小唯不由低聲贊嘆吸收效率較低。化學吸收是在吸收過程中伴有明顯的化學反孩兒應∩,不是純溶解過程。化學吸收效◥率較高,是目前應用較多的有害氣體處理方法。


                本工藝采用的方法就是利飛騰天地用物理與化學的方法處理廢氣的,化學吸收過◆程采用NaOH溶液做萬魂燃燒吸收劑。


                應用堿液吸收有害氣體時,堿液濃度︻的高低對化學吸收的傳質速度有很大的影響。當堿液的 白發老者一愣濃度較低時,化學傳質的速度較低;當提高√堿液濃度時,傳質速度也隨之增大殺機爆閃;當堿液濃度提高到某一●值時,傳質速度達到最大值,此時堿液的濃度稱為臨界濃度;當堿液濃度高於臨界濃度時傳質速度並不增ξ大。


                酸霧凈化塔凈化原理:

                (1)吸風罩--進風管道--風機(或進風段)--進風段第一段濾料層(第一級中和反應段)--第二級濾料層(第二級屈辱中和反應段)旋流板--出風帽蓋--排風管(或吸入段風機)


                (2)酸霧◥凈化塔工作原理:酸霧凈化塔采用氫氧化鈉溶液為吸收中↘和液來凈化酸霧廢氣。氣體由離心通風機壓入或吸入青姣興奮大吼進風段,再向上流動,至第一濾料㊣層,與第一級噴咀噴出的中和液》接觸反應。吸收後的廢氣繼續對方是千仞峰向上流動至第二濾料層,與第二級噴咀噴出的中和液接觸,再次發生中和◢反應,然後通過激動之色旋流板,由風帽和排風管或躲開了斷人魂等人風機排入大氣中。


                酸霧凈↑化塔的特點:

                聚丙烯酸霧凈ζ化塔具有效率高、耐腐在下也不敢保證能夠收蝕性強,高強度、低噪聲、耗電省、體積小,拆♂裝維修方便,輕巧耐用,外 巫師一族形美觀大方等優點.


                目前國內對於腐蝕性氣體(如酸、堿性廢氣)的治理,采用最多的就是液體吸收法治理☆。采』用液體吸收法治理該廢氣,關鍵在於酸霧凈化塔的選擇。


                酸霧凈化塔具有凈化效率高、操作管理〓簡單、使用壽命長的酸、堿性廢氣凈化工藝身上爆發出了恐怖與設備。它具有∑結構簡單、能耗低、凈化效率高和適用範「圍廣的特點,能有效去 島主除氯化氫氣體(HCl)、硝酸氣體(HNO3)、氟化氫氣體(HF)、氨氣(NH3)、硫酸霧(H2SO4)、鉻酸(CrO3)、氰氫㊣ 酸氣體(HCN)、堿蒸氣(NaOH)、硫看來化氫氣體(H2S)、等水溶頓時感覺到性氣體●。采用氫氧╲化鈉為吸收中和液,溶液濃度為空間封鎖8%-16%。


                酸霧廢氣由風管引入凈化塔,經過填料層〓,廢氣與氫氧化鈉吸收液他朝一旁那臉色蒼白進行氣液兩相充分接觸吸收中和反應一臉感激之色,酸霧廢氣經過酸霧☉凈化塔凈化後,再經除霧板脫水除霧後由風機卐排入大氣。吸收液在塔底經水泵增你敢壓後在塔頂噴淋而下,最後回流至塔底循環使用。



                   Exhaust gas mainly NaOH, H2SO4, SO2, H2S, HCl, NO2, HNO3 and other gases, in accordance with the requirements of clean production in the treatment process, first consider the substance of such purification treatment possible is required to meet emissions standards.


                Process description:

                    After the exhaust fan leads from the first into the exhaust gas purification tower mist. Absorber alkaline washing solution is pumped by the circulation pump to the column by packing flows down countercurrent gas mist rise in the gas-liquid filler wetted surface contact, a series of physical and chemical reactions, and due to the concentration difference occurs Biography transfer process, thereby completing the purge process gas, the exhaust gas after dehydration purified by centrifugation extraction fan discharge. Circulating fluid periodically discharged to sewage treatment station.


                Process system components:

                    This process consists of the exhaust gas collection systems, the wind system, exhaust gas purification system, exhaust system structure.


                Gas gathering and pipeline system:

                    Gas gathering and pipeline systems, mainly divided into the exhaust gas collection systems, exhaust systems, and post-emergency transport emissions and clean exhaust emission systems.


                Of the emission control projects, there are exhaust Party (manufacturer) collection, gas collection and this project is directly connected from the lead after the fan outlet Party collection.


                Gas explosion-proof transport induced draft fan to overcome the system resistance. Fan pressure head determined according to the structure of the purification system.


                Process selection:

                    Substances contained in exhaust emissions for the unit, consider packing governance programs spray tower for processing. Spray tower using the principle of absorption to achieve the purpose of treating exhaust.


                    Absorption process using a liquid absorbent process gas mixture to remove one or a few gas process. Some physical effects in the gas dissolved in the solution will occur in this process, which is physical absorption. There is also a chemical reaction between the gas and liquid chemicals, which is chemical absorption. Absorption of gaseous pollutants commonly used in the treatment and recycling.


                    Absorption of law not only absorb harmful gases, but also to get rid of the dust in the exhaust gas, absorption into physical absorption and chemical absorption of two kinds. Purely physical process of dissolution is the physical absorption liquid absorbs harmful gases and vapors. It is suitable for relatively large solubility in water of harmful gases and vapors, generally lower absorption efficiency. Chemical absorption is associated with significant chemical reaction in the absorption process, it is not a pure dissolution process. High chemical absorption efficiency, is the application of more harmful gas treatment.


                   The method used in this process is the use of physical and chemical methods of waste gas treatment, chemical absorption process using NaOH solution as absorbent.


                   The application of lye absorb harmful gases, alkali concentration level has a great influence on the absorption of chemical mass transfer rate. When a lower concentration of lye, chemical mass transfer speed is low; when the alkali concentration increase, the mass transfer rate also increases; when the alkali concentration is increased to a certain value, the maximum rate of mass transfer in this case the concentration of lye called the critical density; mass transfer rate does not increase when the alkali concentration above the critical concentration.


                Mist purification tower purification principle:

                (1) suction hood - inlet pipe - fan (or inlet section) - the first paragraph of section inlet filter layer (first stage reaction section) - the second stage filter layer ( and two in the reaction zone) cyclone - a hood cover - exhaust pipe (or suction fan section)


                (2) mist purification tower works: mist purification tower sodium hydroxide solution to absorb the liquid and to purify exhaust fumes. Gas by the centrifugal fan pressed or sucked into the wind section, and then flows upward to the first filter layer, and the first stage nozzle and sprayed liquid contact reaction. After absorbing the exhaust gas continues to flow upward to the second filter layer, and in contact with the second stage nozzle fluid ejected, and the reaction from happening again, then swirl plate from the hood and into the exhaust pipe or fan atmosphere.


                Mist purification tower Features:

                    Polypropylene acid mist purification tower with high efficiency, corrosion resistance, high strength, low noise, low power consumption, small size, easy disassembly and maintenance, lightweight and durable, elegant appearance and so on.


                    At present, the corrosive gases (such as acids, alkaline gas) governance, using the most is the liquid absorption method of governance. The exhaust gas treatment by liquid absorption, the key is to select mist purification tower.


                   Mist purification tower has a high purification efficiency, operation and management simple, long life acid and alkaline exhaust gas purification technology and equipment. It has a simple structure, low energy consumption, high purification efficiency and a wide range of features, can effectively remove hydrogen chloride gas (HCl), nitric acid gas (HNO3), hydrogen fluoride gas (HF), ammonia (NH3), sulfuric acid mist (H2SO4 ), chromic acid (CrO3), hydrogen cyanide gas (HCN), alkali vapor (NaOH), hydrogen sulfide (H2S), water-soluble gases. Sodium hydroxide to absorb the liquid, solution concentration and 8% -16%.


                   Mist exhaust pipe introduced by the wind purification tower, after packing layer, the exhaust gas and absorbing liquid sodium hydroxide liquid two-phase full access to absorption and reaction, acid mist exhaust gas after purification tower mist purification, and then by dehydration defogging board after demisting by the fan into the atmosphere. After absorbing liquid pump pressurized overhead spray down the bottom, and finally back to the bottoms recycle.
