Ozone panyama ehupfumi:
Ozone (O3), aizivikanwawo superoxide, ndiko allotrope reokisijeni (O2), ndiro gasi ane "kunhuhwira chaiyo" panguva dzekudya tembiricha. Ozone dzinowanzotsigi- richiparadzirwa munyika stratospheric muchadenga ari nekukwirira 10 kusvika 50 km. Panguva dzekudya tembiricha uye kumanikidzwa, pasi Kuwanda ozone chinhu Hauoneki gasi, kana wevasungwa kunosvika 15%, zvinoratidza yebhuruu rakachenuruka ruvara.
Ozone mushonga ehupfumi:
Ozone ndiyo isina chaizvo, nehafu upenyu manyowa anenge 20 kusvika nemaminitsi 30. Sezvo tembiricha kuwedzera, manyowa mwero inowedzerawo. Apo tembiricha kwazvo 100 ° C, iyo manyowa kwazvo kwazvo. Apo tembiricha rinosvika 270 ° C, rinogona dzikwanise okisijeni pakarepo. Ozone uchiora nokukurumidza mumvura pane mumhepo. In mvura ine tsvina, ozone inogona nokukurumidza yaora kupinda oxygen.
Ozone ane simba oxidizing kugona, iri nechepazasi chete pane fluorine. pfuma iyi kunyanya kushandiswa kushandisirwa. Ozone inotsigira combustion. Kana combustibles vari kupinzwa ozone gasi ambient, combustion zvakawanda chaizvo kupfuura oxygen.
Ozone rutapudzo kuita
A, Ozone rutapudzo maitiro pamwe inorganic zvinhu
Ozone ikasakendenga pamwe ferrous simbi, Mn2 +, sulfide, thiocyanide, cyanide, kuiisa chlorine, etc.
Zvakaita se:
B, Ozone maitiro pamwe makemikari nyaya
Zvingaitwa ozone pamwe makemikari nyaya mumvura kuoma zvikuru.
(1) Zvaakazoita kuti ozone pamwe olefinic yeimwe
Ozone nyore zvaanoita pamwe olefinic yeimwe vane miviri zvisungo, uye yokupedzisira zvibereko kuita angava musanganiswa monomeric, polymeric, kana vakadzungairira ozonides. Ozone oxides anoora kupinda aldehydes uye acids.
(2) Zvaakazoita kuti ozone ne zvinonhuwirira yeimwe
Zvakaitwa pakati ozone uye zvinonhuwirira yeimwe anononoka, ari oxidation kutevedzana kwezviitiko ozone pamwe zvinotevera: benzene <naphthalene <phenanthrene.
(3) zvaanoita pamwe mapuroteni yenyukireya (amino acid) uye makemikari amoniya
The oxidation kutevedzana kwezviitiko ozone zvinotevera wemisanganiswa iri
Alkenes> Amines> Phenols> Polycyclic Kwezvinonhuhwirira Mahydrocarbon> Alcohols> Aldehydes> Paraffins
Toxicity uye corrosivity
Ozone chinhu chinokuvadza gasi. Kana wevasungwa uri 6.25 × 10-6mol / L (0.3mg / L), ine muviri kunzwa meso, mhuno nepahuro. Concentration (6.25-62.5) × 10-5mol / L (3 ~ 30mg / L), achaita kutemwa uye nemakanzuru kuoma kufema zvomukati; wevasungwa 3,125 × 10-4 ~ 1.25 × 10-3mol / L (15 ~ 60mg / L), zviri kukuvadza muviri womunhu. The toxicity iri chokuita kuonana nguva. Somuenzaniso, kwenguva refu kugara ozone wevasungwa 1,748 × 10-7mol / L (4ppm) anogona kukonzera zvachose mwoyo chirwere, asi kugara ozone pazasi 20ppm hakuiti kupfuudza 2h, hapana zvachose kuvanhu muviri. Naizvozvo, zvinobvumidzwa kukosha ozone wevasungwa uri 4,46 × 10-9 mol / L (0.1 ppm) 8 h. Sezvo munhuwi ozone ari chaizvo pfungwa, kana kuisa pfungwa 4,46 × 10-9 mol / L (0.1 ppm), vanhu vanofunga nayo nyore. Saka, kunyange ozone munyika yave kushandiswa kwemakore anopfuura zana, asi hapana mashoko rufu nokuda ozone chepfu.
Ozone iri zvikuru oxidizing, kuwedzera goridhe uye Platinum, ozonized mhepo ine kungatikanganisa sei zvinenge zvose simbi. Aluminum, zingi, kutungamirira uye ozone vari oxidized zvakasimba, asi Chrome tubhokisi alloys vari substantially isina ozone ngura. Naizvozvo, Chrome-simbi chiwanikwa (Stainless simbi) rinowanzoshandiswa mukurima kugadzira zvikamu ozone urwu michina uye zvekupfakira midziyo kuti vari zvakananga nevanhu ozone.
Safe ozone wevasungwa
Maererano nebhuku rinonzi "Ozone Technology Application Collection" rakapepetwa Tsinghua University, wevasungwa kuti ozone fomu iri Classified yakachena wevasungwa mumhepo, vakashandisa wevasungwa, mvura chikumbiro wevasungwa, kwezvakatipoteredza yevasungwa uye vachinzwisisa yevasungwa.
◎ Ozone indasitiri utsanana mitemo: International Ozone Association: 0.1 ppm kugarotamba kwemaawa 10; United States, Germany, France, Japan: 0.1 ppm kugarotamba kwemaawa 8, China: 0,15 ppm kugarotamba kwemaawa 8
◎ The ozone leakage kunoitwa mhuri ozone disinfection cabinet haafaniri kupfuudza 0.2 MG / m3 (kureva 1.5 metres kure), uye residual wevasungwa pashure disinfection rimwe kutenderera haafaniri kupfuudza 0.3 MG / m3.
Air Chikumbiro wevasungwa
◎ Air yokunatswa zvinoda ozone wevasungwa uri pakati 1 MG / m3 10 MG / m3.
◎ Ozone zvikuru mubasa pasi tembiricha uye yakakwirira mwando ezvinhu, kana hama mwando dererei pane 45%, asi ozone ane anenge asina kuuraya zvainoita yakaturikwa tusingaoneki mudenga, apo zvainoita zvishoma nezvishoma kunowedzera pa 60% uye rinosvika vaifanira pa 95% mwando.
◎ Ozone disinfection zvokudya kubudiswa workshop, 0.5 ~ 1.0 ppm anogona kuuraya 80% zvakasikwa utachiona mudenga.
◎ Cold okuchengetera disinfection zvinoda ozone wevasungwa 6 kusvika 10 ppm, After kubatwa ozone uye kuvhara yaichengeterwa kwemaawa 24, kuti kwemabhakitiriya kuuraya mwero iri vanenge 90% uye Foroma kuuraya mwero anenge 80%.
◎ Munguva kuchengetera zvibereko, 2 3 ppm pamusoro ozone anogona tunodzivisa kukura chakuvhuvhu, uye kuwedzera amatura nguva.
Ozone wevasungwa mumvura kushanda
◎ Vimba mvura ozone yokuzvinatsa, international mwero iri 0,4 MG / L (0.4ppm) kuonana nguva: 4 maminitsi.
◎ The ichiputswa ozone pamwero vakaramba pa 0.1-0.5 MG / L kwemaminitsi 5-10 kuti zvakafanana disinfection zvinangwa.
◎ Ozone mumvura disinfection uye mbereko ndiyo nokukurumidza, utachiona vari kuurayiwa mukati 0.5 1 miniti. At wevasungwa of 4 MG / L, kuti chiropa B utachiona inactivation kuuraya mwero iri 100% muna 1 miniti.
◎ Herbold anoshuma: At 20 ° C, 0.43 MG / L (0.43ppm) ozone wevasungwa, unogona kuuraya E. coli kubudikidza 100%, uye 0.36 chete MG / L (0.36ppm) ozone wevasungwa raida pa 10 ° C.
◎ Kana ozone wevasungwa uri 0.25 kusvika 38 MG / L, zvinotora mumasekonzi mashomanana kuti inactivate zvachose chiropa A utachiona (HAV).
◎ Mineral mvura disinfection vanoda kuva ozone wevasungwa kuti 0,4 ~ 0.5mg / L, unogona kusangana mbereko uye unhu zvinodiwa.
◎ water kurapwa vanofanira kusvika ozone wevasungwa kuti 0.3 ~ 0.5mg / L.
