吸收塔也可用于溶剂回收。喷淋吸收塔、湿法尾气净化塔的优点：可用于废气浓度高的场合（大于50g/m3）吸收剂容易获得能适应废气流量、浓度的波动能吸收可聚合的有机化合物不易着火、不需要特殊的安全措施如已有废水处置装置，则用水作为吸收剂更为方便。1.塑料造粒光氢离子净化处理设备该设备核心中的纳米光催化触媒材料（GC-100）是一种吸收光能后，能在其表面产生催化反应的物质，其功能类似于植物的叶绿素。当特定纳米波长的紫外光照射光催化触媒材料（GC-100）时，其表面发生光催化氧化还原反应。光催化触媒材料（GC-100）吸收光子后在其表面产生电子（E—）和空穴（H+），将吸收的光能转化成化学能，即具有光催化作用。当光催化触媒材料（GC-100）与空气中的水接触时，表面就吸附H2O、O2、OH—，H2O、OH—被空穴（H+）所氧化，O2被电子（E—）还原，反应室如下：H2O+H+→OH.+H+O2+E—→O2-OH—基团的氧化能力较强，使有机物氧化，***终分解为水和CO2。2．塑料造粒高活化生物净化塔过滤净化装置采用生物菌，生物菌性能、净化效率、减少二次污染、达到***环保标准，一个重要原因在于环境保护的综合考虑。3．塑料造粒大型等离子烟气处理设备在外加电场的作用下，介质放电产生大量携能电子轰击污染物分子，使其电离、解离和激发，然后便引发了一系列复杂的物理、化学反应，使复杂大分子污染物转变为简单小分子安全物质，或使用******物质转变成***无害或低毒低害的物质，从而使污染物得以降解去除。因其电离后产生的电子平均能量在10ev，适当控制反应条件可以实现一般情况下难以实现或速度很慢的化学反应变得十分快速。优势：1.具有一次性净化效率高，能同时净化多种污染物;2.防火性能采用开关，电源，电路三重自动保护，的净化功能，无须专人看管;3.设备***少，运行成本低;4.安全稳定，维护方便，使用寿命长;5.净化效率高，无二次污染。Aboutactivatedcarbonadsorptionbox,activatedcarbonadsorptionpurificationdevice:Activatedcarbonadsorptionandpurificationdeviceisusuallyusedfordeeppurificationoforganicwastegasorhighpriceorganicsolventrecovery.Activatedcarbonwithlargesurfaceareaandhighadsorptioncapacitywasusedasadsorbenttoadsorbandpurifyorganicwastegasandcleancleanair.Whentheactivatedcarbonreachesthesaturatedcriticalstate,theactivatedcarbonisdesorbedandregeneratedbysteamorinertgas,andtheregeneratedactivatedcarboncontinuestobeused,andthedissolvedorganicwastegasisactuallyaconcentratedorganicwastegasflow.Ifithasthevalueofrecovery,itcanbefurtherrecoveredandtreated.Ifthereisnorecoveryvalue,itisgenerallyusedheat.Oxidation(RTO)orcatalyticoxidation(RTO,photooxidationcatalysis,etc.)forfinalpurification.Ifitisanorganicwastegasdischargedintermittently,aactivatedcarbonadsorptionbedisgenerallyused.Ifitisacontinuousemissionoforganicwastegas,twoactivatedcarbonadsorptionbedsshouldbeinstalled,alternatelyadsorbinganddesorbing.Fortheorganicwastegaswhichishigherthan40C,thecondensersaregenerallyincreasedinthesystem,andthenthehightemperatureorganicwastegasflowiscooledanddriedfirstandthenadsorbedandpurify.Applicationofactivatedcarbonadsorptionpurificationdevice:Itiswidelyusedinallkindsofindustrialorganicwastegastreatment,suchasprintingorganicwastegastreatment,spraypaintorganicwastegastreatment,papermillorganicwastegasexhausttreatment,coatingprocessingwastegastreatment,variouselectronicfactoryexhaustpurificationtreatment,semiconductorfactoryexhaustpurificationtreatment,lithiumbatteryplantwastegaspurificationtreatment,andlarge-scaleresearch.Theexhaustpurgetreatmentoftheventilatorandsoon.Theorganicwastegasescanbepurified:benzene,alcohols,ketones,esters,gasolineandotherorganicwastegases.Itcanbeusedforpurificationoforganicwastegaswithlowconcentrationandlargeairvolume,andcanalsobeusedforpurificationoforganicwastegaswithhighconcentrationandintermittentdischarge.Onthesprayabsorptiontowerandthewettailgaspurificationtower:Alsocalledspraypurificationtower,chemicalwashingtower.Themainprincipleistousedifferentchemicalabsorbentsaccordingtothecompositionoftheodor,asthecontactbetweenthewashingspraysolutionandtheodormoleculesinthegas,totransfertheodorcomponentsinthegasphasetotheliquidphase,andtoremovetheodoroussubstancesfromthechemicalreagentsandtheodorcomponentsandtheoxidationorotherchemicalreacti***.Agoodmethodfortreatingwastegasinachemicalplant.Thecommonlyusedabsorbentsarewater,oil(hydrocarbon),ethyltwoalcoholether,hypochloritesolution,alkalinesolution,acid,ammonia,sulfitesolution,highpotassiumacidsolution,peroxideacid,etc.Thechemicalabsorptionliquidspraysdownfromthetopofthetower,andtheexhaustgasflowsupwa***.Theodorandtheabsorptionliquidarefullycontacted,andthereactionisremoved.Absorptionliquidandexhaustgasflowratio(liquid/gasratio)isgenerally1:3L/m3,packingheightisgenerally2~5meters,gastowerflowrateisgenerally0.5~1M/sec.Thepackedcolumnwithgoodoperationcanachievemorethan90%deodorizingeffect.Schematicdiagramofsprayabsorptiontowerandwettailgaspurificationtower.0091sprayabsorberprocessflowgApplicationofsprayabsorptiontowerandwettailgaspurificationtower:Thechemicalwashingmethodscanbeusedtotreattheodorsubstancesincludingorganicsulfurcompounds(thiols,thioether),nitrogenouscompounds(amines),organicacids,phenol,cresol,acetaldehyde,alcohols,organicwastegascontainingchlorinatedhydrocarb***,oxygencontaininghydrocarb***,halidesandsoon.Itisoftenusedinthepurificationofinorganicpollutants,suchasHCl,SO2,NOx,NH3andotherwastegases.Itissuitableforexhaustpurification,organicwastegastreatmentandVOCpurificationinsludgetreatment,food,petroleum,chemical,pharmaceutical,textile,coatingandotherindustries.)
