Ozone Izakhiwo:
Ozone (O3), eyaziwa nangokuthi superoxide, kuyinto allotrope umoya-mpilo (O2), okuyinto igesi nge "nephunga ekhethekile" ashisa evamile. Ozone ikakhulukazi basakaza emkhathini esemkhathini ezingeni ukuphakama km 10 kuya 50. Ngezinye lokushisa evamile futhi ingcindezi, emakamu low we-ozone yigesi kungekho nto enemibala emihle, lapho emakamu ifinyelela 15%, ekubonisa umbala okhanyayo okwesibhakabhaka.
Ozone chemical izakhiwo:
Ozone ingahlalisekanga kakhulu, nenxenye ukuphila yokubola imayelana 20 kuya kwengu-30. Njengoba ukwanda lokushisa, noqhekeko izinga iyakhula. Lapho izinga lokushisa udlula 100 ° C, noqhekeko okukhulu kakhulu. Lapho izinga lokushisa ifinyelela 270 ° C, ke zingaphendulwa zibe yizindawo yokuhlanganela umoya-mpilo ngokushesha. Ozone ubola ngokushesha emanzini kuka emoyeni. Ngo amanzi equkethe ukungcola, i-ozone kungenziwa ngokushesha ukubola zibe umoya-mpilo.
Ozone has a ikhono eqinile oxidizing, okuyinto aphansi kuphela kuka sasekhaya. Le mpahla ikakhulukazi esetshenziswa uhlelo lwayo lokusebenza. Ozone isekela amandla omlilo. Lapho umlilo nezinto ezinokuvutha zifakwa-ozone igesi kuma, amandla omlilo okukhulu ezingaphezu kuka-oksijini.
Ozone ukunciphisa ukusabela
A, Ozone ukunciphisa ukuphendula izinto wezinto
Ozone ihlangana yensimbi ayoni, Mn2 +, sulfide, thiocyanide, cyanide, chlorine, njll
Njenge:
B, Ozone ukuphendula udaba eziphilayo
Ukusabela we-ozone nge daba eziphilayo emanzini luyindida kakhulu.
(1) Indlela Abasabela we-ozone nge compounds olefinic
Ozone kalula ihlangana compounds olefinic kokuba izibopho kabili, futhi umphumela wokugcina ukuthi bayavuma kungenzeka nenye monomeric, polymeric, noma ozonides uvalo. Ozone oxides ukubola ku aldehydes futhi acid.
(2) Ukusabela we-ozone nge ezinuka kamnandi
Ukusabela phakathi i-ozone futhi ezinuka kamnandi uyephuza, ukulandelana namachibi we-ozone nge okulandelayo: benzene <naphthalene <phenanthrene.
(3) ihlangana amaprotheni yenuzi (acid acid) kanye ammonia organic
Ukulandelana namachibi we-ozone ku Izingxube Okulandelayo
Alkenes> ama> Phenols> Polycyclic elimnandi hydrocarbon> alcohols> Aldehydes> Paraffins
Ubuthi kanye corrosivity
Ozone yigesi elimazayo. Lapho lokuhlushwa kuyinto 6,25 × 10-6mol / L (0.3mg / L), it has a umuzwa emnandi ukuze amehlo, ikhala nomphimbo. Lokuhlushwa (6.25-62.5) × 10-5mol / L (3 ~ 30mg / L), kuzokwenza ikhanda futhi ukukhubazeka sendawo kwezitho zokuphefumula; okuhlushwa 3,125 × 10-4 ~ 1.25 × 10-3mol / L (15 ~ 60mg / L), kuyingozi ukuba umzimba womuntu. I ubuthi nayo ezihlobene isikhathi contact. Ngokwesibonelo, yesikhathi eside ukuchayeka-ozone lokuhlushwa 1,748 × 10-7mol / L (4ppm) kungabangela unomphela isifo senhliziyo, kodwa ukuchayeka-ozone ngezansi 20ppm ingeqi 2 amahora, akukho nobe singalimali siphelwane umzimba womuntu. Ngakho-ke, inani avumelekile emakamu lwe-ozone 4,46 × 10-9 Mol / L (0.1 ppm) 8 h. Njengoba iphunga lwe-ozone is kakhulu bagxila, lapho emakamu kuyinto 4,46 × 10-9 Mol / L (0.1 ppm), abantu bazizwe kalula. Ngakho-ke, ngisho i-ozone emhlabeni iye yasetshenziswa isikhathi esingaphezu kweminyaka eyikhulu, kodwa akukho mbiko sokufa ngenxa lwe-ozone ubuthi.
Ozone kuyinto oxidizing kakhulu, ngaphezu yegolide ne-platinum, emoyeni ozonized kunomphumela ezonakalisayo cishe zonke izinsimbi. Aluminium, zinc, okuhola futhi i-ozone yabafile oxidized, kodwa Alloys-chrome equkethe makhulu khulula we-ozone ukugqwala. Ngakho-ke, i-chrome-yensimbi ingxubevange (insimbi engagqwali) livame ukusetshenziselwa ekukhiqizeni okwenza izingxenye we-ozone ekhiqiza imishini kanye nempahla ukugcwaliswa ezisebusweni ukuxhumana ngqo i-ozone.
Safe-ozone lokuhlushwa
Ngokwencwadi ethi "Ozone Ubuchwepheshe Isicelo Collection" eyahlelwa Tsinghua University, lokuhlushwa i-ozone kwisicelo libhekwa emakamu ephephile emoyeni, isicelo okuhlushwa, isicelo amanzi okuhlushwa, okuhlushwa kwemvelo kanye okuhlushwa waqonda.
◎ Ozone amazinga inhlanzeko umkhakha: International Ozone Association: 0.1 ppm, ukuchayeka amahora 10; United States, eJalimane, eFrance, Japan: 0.1 ppm, ukuchayeka amahora ayi-8, China: 0.15 ppm, ukuchayeka amahora ayi-8
◎ I ukuvuza-ozone yi yasendlini-ozone magciwane iKhabhinethi ngeke sidlule 0.2 mg / M3 (ubheke 1.5 amamitha kude), kanye lokuhlushwa asalile emva magciwane oyedwa umjikelezo ngeke sidlule 0.3 mg / M3.
Air isicelo lokuhlushwa
◎ Air uhlanzekile zidinga i-ozone lokuhlushwa kuyinto ephakathi kuka-1 mg / M3-10 mg / M3.
◎ Ozone iyasebenza ngaphezulu lokushisa ongaphakeme futhi high umswakama imvelo, uma umswakama nesihlobo ingaphansi kwe 45%, i-ozone esemkhathini has cishe awekho umphumela sigameko izilokazane ezincane okwesikhashana emoyeni, kuyilapho Effect Its kancane kancane kwandisa at 60% futhi ifinyelela esiphezulu ngesikhathi 95% umswakama.
◎ Ozone magciwane izocubungulwa ukudla workshop, 0.5 ~ 1.0 ppm bangambulala 80% amabhaktheriya zemvelo emoyeni.
◎ Cold isitoreji magciwane idinga i lokuhlushwa i-ozone-6 kuya ku-10 ppm, Ngemva selashwe-ozone avale okugcinwa amahora angu-24, ama-bacterium ukubulala izinga imayelana 90% kanjalo nokubulawa isikhunta izinga imayelana 80%.
◎ Phakathi isitoreji izithelo, 2 kuya ku-3 ppm we-ozone singavimbela ukukhula isikhutha, futhi banwebe isikhathi isitoreji.
Ozone lokuhlushwa isicelo amanzi
◎ Thepha amanzi-ozone zokuhlanjululwa, standard international 0.4 mg / L (0.4ppm) contact isikhathi: imizuzu 4.
◎ I ziyoncibilika-ozone ezingeni zigcinwe ngaso 0.1-0.5 mg / L for 5-10 imizuzu izinjongo ezivamile magciwane.
◎ Ozone emanzini magciwane futhi inzalo kushesha, ama-bacterium zibulawa ngaphakathi 0.5 kuya 1 iminithi. Ngezinye lokuhlushwa 4 mg / L, i-hepatitis B igciwane inactivation ukubulala izinga 100% elingu-1.
◎ Herbold uyabika: At 20 ° C, 0,43 mg / L (0.43ppm) lwe-ozone okuhlushwa, ingakubulala E. coli by 100% futhi mg 0,36 kuphela / L (0.36ppm) lwe-ozone lokuhlushwa liyadingeka 10 ° C.
◎ Uma emakamu lwe-ozone 0.25 kuya ku-38 mg / L, kuthatha imizuzwana embalwa kuphela okunqanda ngokuphelele nokohlobo A igciwane (HAV).
◎ amaminerali amanzi magciwane Udinga lokuhlushwa i-ozone ka 0.4 ~ 0.5mg / L, kungaba ukuhlangabezana inzalo kanye nekhwalithi nezimfuneko.
ukwelashwa ◎ amanzi asemabhodleleni kufanele sifinyelele lokuhlushwa i-ozone ka 0.3 ~ 0.5mg / L.
