  02 #行(xing)業發展(zhan)#
 
  (1)行業整體發展情況
 
  2023年(nian)我國經濟形勢復(fu)雜(za)嚴峻,對VOCs治(zhi)(zhi)理(li)(li)行業(ye)的(de)發展影響(xiang)較大,目前VOCs治(zhi)(zhi)理(li)(li)技術(shu)和(he)治(zhi)(zhi)理(li)(li)市場仍有不(bu)足(zu),如還存在大量低效(xiao)失效(xiao)的(de)治(zhi)(zhi)理(li)(li)設施,部分(fen)技術(shu)運用不(bu)合(he)理(li)(li),技術(shu)的(de)安全性重視(shi)不(bu)夠,關(guan)鍵吸(xi)附(fu)、催(cui)化材料性能標準還不(bu)完(wan)善;行業(ye)競爭(zheng)加劇,企業(ye)融(rong)資困難(nan),規模擴張受到影響(xiang),整(zheng)體(ti)利潤率(lv)降低,低價(jia)中(zhong)標現象屢見不(bu)鮮等。
 
  目(mu)前大型污(wu)染(ran)(ran)源的(de)(de)(de)(de)治(zhi)(zhi)(zhi)(zhi)理(li)(li)工(gong)作已(yi)經基本完成(cheng)(cheng),我國的(de)(de)(de)(de)VOCs治(zhi)(zhi)(zhi)(zhi)理(li)(li)工(gong)作已(yi)經進(jin)入到(dao)對(dui)(dui)污(wu)染(ran)(ran)源的(de)(de)(de)(de)精(jing)細化(hua)管控和深度治(zhi)(zhi)(zhi)(zhi)理(li)(li)階段(duan)。2023年主要集(ji)中在(zai)對(dui)(dui)簡易低(di)(di)效(xiao)治(zhi)(zhi)(zhi)(zhi)理(li)(li)設(she)(she)(she)施(shi)(shi)的(de)(de)(de)(de)改(gai)進(jin)提(ti)升(sheng)和新上項(xiang)目(mu)的(de)(de)(de)(de)治(zhi)(zhi)(zhi)(zhi)理(li)(li)上。如對(dui)(dui)現有(you)的(de)(de)(de)(de)低(di)(di)溫等離子/光催化(hua)/光氧化(hua)等低(di)(di)效(xiao)治(zhi)(zhi)(zhi)(zhi)理(li)(li)設(she)(she)(she)施(shi)(shi)的(de)(de)(de)(de)改(gai)造(zao)(zao),更換為沸(fei)石轉輪吸(xi)(xi)(xi)附(fu)濃縮、RTO、RCO、活(huo)性(xing)(xing)炭吸(xi)(xi)(xi)附(fu)等高效(xiao)治(zhi)(zhi)(zhi)(zhi)理(li)(li)設(she)(she)(she)備;對(dui)(dui)部分未達(da)到(dao)排放要求的(de)(de)(de)(de)治(zhi)(zhi)(zhi)(zhi)理(li)(li)設(she)(she)(she)施(shi)(shi)提(ti)標改(gai)造(zao)(zao),如部分活(huo)性(xing)(xing)炭/活(huo)性(xing)(xing)碳纖維(wei)吸(xi)(xi)(xi)附(fu)回收設(she)(she)(she)備增加沸(fei)石轉輪吸(xi)(xi)(xi)附(fu)濃縮設(she)(she)(she)備,以實現污(wu)染(ran)(ran)源的(de)(de)(de)(de)深度治(zhi)(zhi)(zhi)(zhi)理(li)(li);對(dui)(dui)設(she)(she)(she)計不(bu)合理(li)(li)難(nan)以正常(chang)運(yun)行(xing)的(de)(de)(de)(de)治(zhi)(zhi)(zhi)(zhi)理(li)(li)設(she)(she)(she)施(shi)(shi)的(de)(de)(de)(de)改(gai)造(zao)(zao),如針(zhen)對(dui)(dui)含(han)有(you)酸堿(jian)成(cheng)(cheng)分的(de)(de)(de)(de)RTO治(zhi)(zhi)(zhi)(zhi)理(li)(li)設(she)(she)(she)施(shi)(shi)進(jin)行(xing)工(gong)藝提(ti)升(sheng),完善預處理(li)(li)工(gong)藝等。
 
  (2)VOCs治理(li)技(ji)術水平
 
  近(jin)幾年,我國(guo)VOCs治(zhi)理技術(shu)水(shui)平(ping)明顯提升,部分裝(zhuang)(zhuang)備(bei)已(yi)經(jing)達到(dao)或接近(jin)國(guo)際先進水(shui)平(ping),治(zhi)理工(gong)藝逐漸(jian)趨于(yu)(yu)成(cheng)熟。活(huo)性炭/活(huo)性碳纖(xian)維、氧化(hua)(hua)(hua)催化(hua)(hua)(hua)劑等凈(jing)化(hua)(hua)(hua)材料生(sheng)產水(shui)平(ping)明顯進步;用于(yu)(yu)VOCs治(zhi)理的(de)沸石分子(zi)篩、吸(xi)(xi)附(fu)(fu)樹(shu)(shu)脂的(de)性能和(he)制(zhi)造(zao)能力實(shi)現了(le)突(tu)破;工(gong)藝設(she)備(bei)方(fang)面:沸石轉(zhuan)輪、RTO/RCO、吸(xi)(xi)附(fu)(fu)回收(shou)裝(zhuang)(zhuang)置(zhi)(樹(shu)(shu)脂吸(xi)(xi)附(fu)(fu)裝(zhuang)(zhuang)置(zhi)、活(huo)性炭移動床吸(xi)(xi)附(fu)(fu)裝(zhuang)(zhuang)置(zhi)、生(sheng)物凈(jing)化(hua)(hua)(hua)裝(zhuang)(zhuang)置(zhi)等)實(shi)現了(le)突(tu)破和(he)改進。工(gong)藝設(she)計方(fang)面:針對復雜工(gong)況(kuang)的(de)組(zu)合(he)凈(jing)化(hua)(hua)(hua)工(gong)藝設(she)計水(shui)平(ping)不斷提升,重點行業的(de)凈(jing)化(hua)(hua)(hua)工(gong)藝技術(shu)路線逐漸(jian)清(qing)晰。
 
  (3)循環(huan)利用低碳治(zhi)理(li)模式(shi)發展(zhan)迅速
 
  為解決(jue)大量(liang)中(zhong)小型污(wu)染(ran)源VOCs治(zhi)理(li)(li)(li)問題,實現(xian)資源循環利用,在《2020年(nian)揮(hui)發性有機物(wu)治(zhi)理(li)(li)(li)攻堅(jian)方案》、2022年(nian)《臭(chou)氧污(wu)染(ran)防治(zhi)攻堅(jian)行動(dong)(dong)方案》和2023年(nian)《空氣質量(liang)持續改(gai)善行動(dong)(dong)計劃》中(zhong)均提出建(jian)設(she)涉(she)VOCs“綠島”項目(mu),統籌規劃建(jian)設(she)活性炭集中(zhong)處理(li)(li)(li)中(zhong)心(xin)、溶劑回收中(zhong)心(xin)和集中(zhong)涂裝中(zhong)心(xin),以實現(xian)VOCs集中(zhong)高效低(di)碳處理(li)(li)(li)。
 
  采(cai)用“綠(lv)(lv)島”治理(li)模(mo)式進行綜合治理(li),既可以保(bao)證污染源的(de)(de)(de)達(da)標排放,又可以保(bao)證設施經濟運行,近年來得到了快速發(fa)展。針對不同(tong)的(de)(de)(de)應用場景,“綠(lv)(lv)島”治理(li)模(mo)式具體有(you)(you)三類(lei)(lei)應用案(an)例。一(yi)是在吸附劑(ji)(ji)使(shi)用量(liang)大的(de)(de)(de)地區(城市(shi)、園(yuan)區和(he)產業集(ji)(ji)群(qun)(qun)),建立(li)活性(xing)炭分散吸附+集(ji)(ji)中(zhong)(zhong)(zhong)再生處置(zhi)(zhi)中(zhong)(zhong)(zhong)心(xin)(xin),同(tong)步完善吸附劑(ji)(ji)規范(fan)采(cai)購、統(tong)一(yi)收(shou)集(ji)(ji)、集(ji)(ji)中(zhong)(zhong)(zhong)再生的(de)(de)(de)管理(li)體系,實現活性(xing)炭資(zi)源的(de)(de)(de)循(xun)環利用。二是在同(tong)類(lei)(lei)型有(you)(you)機溶(rong)劑(ji)(ji)使(shi)用量(liang)較大的(de)(de)(de)園(yuan)區和(he)集(ji)(ji)群(qun)(qun),建立(li)溶(rong)劑(ji)(ji)分散回(hui)收(shou)+集(ji)(ji)中(zhong)(zhong)(zhong)提純/處置(zhi)(zhi)中(zhong)(zhong)(zhong)心(xin)(xin),實現有(you)(you)機溶(rong)劑(ji)(ji)的(de)(de)(de)循(xun)環利用。三是在同(tong)一(yi)類(lei)(lei)別工業涂裝企(qi)業聚集(ji)(ji)的(de)(de)(de)園(yuan)區和(he)集(ji)(ji)群(qun)(qun),建設集(ji)(ji)中(zhong)(zhong)(zhong)涂裝中(zhong)(zhong)(zhong)心(xin)(xin),對噴涂廢(fei)氣進行統(tong)一(yi)高效治理(li)。這些應用案(an)例在行業內發(fa)揮了較好(hao)的(de)(de)(de)示范(fan)作用,成功帶(dai)動(dong)了從(cong)事(shi)活性(xing)炭分散吸附+集(ji)(ji)中(zhong)(zhong)(zhong)再生和(he)溶(rong)劑(ji)(ji)分散回(hui)收(shou)+集(ji)(ji)中(zhong)(zhong)(zhong)提純/處置(zhi)(zhi)企(qi)業的(de)(de)(de)快速規模(mo)化發(fa)展。
