Ukuthabatha
Iimvavanyo zenziwa ngokuchasana kunye nokusebenza kakuhle kobunzima bokucoca, kunye nemithetho yokutshintsha uthuli olubambe ukuxhathisa kunye nokusebenza kakuhle kwesihluzo kuphononongwe, ukusetyenziswa kwamandla okucoca kubalwa ngokwendlela yokubala yokuphumelela kwamandla ecetywa yi-Eurovent 4. /11.
Kufunyaniswa ukuba iindleko zombane zokucoca, zonyuka ngokunyuka kokusetyenziswa kwexesha kunye nokuchasana.
Ngokusekwe kuhlalutyo lweendleko zokubuyisela isihluzi, iindleko zokusebenza kunye neendleko ezibanzi, indlela yokumisela ukuba isihluzo kufuneka sitshintshwe nini siyacetywa.
Iziphumo zibonise ukuba ubomi benkonzo yokwenene yesihluzi buphezulu kunokuba buchazwe kwi-GB/T 14295-2008.
Ixesha lokutshintshwa kwesihluzi kwisakhiwo jikelele soluntu kufuneka kugqitywe ngokweendleko zokutshintsha umthamo womoya kunye neendleko zokusetyenziswa kwamandla okusebenza.

Iintshayelelo
Impembelelo yomgangatho womoya kwimpilo yabantu ibe yenye yezona zinto zibalulekileyo ezichaphazelekayo luluntu.
Okwangoku, ungcoliseko lomoya wangaphandle olumelwe yi-PM2.5 lubi kakhulu e-China. Ke ngoko, ishishini lokucoca umoya likhula ngokukhawuleza, kwaye izixhobo zokucoca umoya omtsha kunye nesicoci somoya zisetyenziswa ngokubanzi.
Ngo-2017, malunga ne-860,000 yokungenisa umoya omtsha kunye ne-7 yezigidi zokucoca zathengiswa e-China. Ngolwazi olungcono lwe-PM2.5, izinga lokusetyenziswa kwezixhobo zokucoca liya kunyuka ngakumbi, kwaye kungekudala liya kuba sisixhobo esiyimfuneko kubomi bemihla ngemihla. Ukuthandwa kolu hlobo lwezixhobo kuchaphazeleka ngokuthe ngqo kwiindleko zokuthenga kunye neendleko zokuqhuba, ngoko ke kubaluleke kakhulu ukufunda uqoqosho lwayo.
Iiparamitha eziphambili zokucoca ziquka ukuhla koxinzelelo, inani leengqungquthela eziqokelelweyo, ukuqokelela kakuhle kunye nexesha lokusebenza. Iindlela ezintathu zinokumkelwa ukugweba ixesha lokutshintsha isihluzi sokucoca umoya. Eyokuqala kukulinganisa utshintsho lokumelana ngaphambi nangemva kokucoca ngokwesixhobo sokuva uxinzelelo; Okwesibini kukulinganisa ingxinano yesuntswana lentwana kwindawo ekuphuma kuyo ngokwesixhobo sevammi. Elokugqibela lixesha lokuhamba, oko kukuthi, ukulinganisa ixesha lokuqhuba kwesixhobo.
Ithiyori yemveli yokutshintshwa kwesihluzo kukulinganisa iindleko zokuthenga kunye neendleko zokuqhuba ngokusekelwe ekusebenzeni kakuhle. Ngamanye amazwi, ukwanda kokusetyenziswa kwamandla kubangelwa ukunyuka kokuchasana kunye neendleko zokuthenga.
njengoko kubonisiwe kuMfanekiso 1
Umzobo we-1 ijika lokumelana nesihlungi kunye neendleko
Injongo yeli phepha kukuphonononga ukuphindaphindwa kokutshintshwa kwesihluzo kunye nefuthe lalo kuyilo lwesixhobo esinjalo kunye nenkqubo ngokuhlalutya ulungelelwaniso phakathi kweendleko zamandla okusebenza okubangelwa kukwanda kokumelana nesihluzo kunye neendleko zokuthenga eziveliswa kukutshintshwa rhoqo kwesixhobo sokucoca. isihluzi, phantsi kwemeko yokusebenza yomthamo omncinci womoya.
I-1.I-Filter Efficiency and Resistance Tests
1.1 Isixhobo soVavanyo
Iqonga lovavanyo lokucoca ikakhulu liqulunqwe ngala malungu alandelayo: inkqubo yokuhambisa umoya, isixhobo sokwenza uthuli olwenziweyo, isixhobo sokulinganisa, njl.njl., njengoko kubonisiwe kuMfanekiso 2.
Umzobo 2. IZiko loVavanyo
Ukwamkela i-frequency conversion fan kwi-air duct system yelabhoratri ukulungelelanisa umthamo womoya osebenzayo wesihluzi, ngaloo ndlela ukuvavanya ukusebenza kokucoca phantsi komthamo womoya owahlukileyo.
1.2 Isampulu yoVavanyo
Ukuze kuphuculwe ukuphinda-phinda kovavanyo, izihluzi zomoya ezi-3 eziveliswe ngumenzi ofanayo zakhethwa. Njengoko izihluzi zohlobo lwe-H11, i-H12 kunye ne-H13 zisetyenziswa ngokubanzi kwimarike, i-H11 i-grade filter isetyenziswe kolu vavanyo, kunye nobukhulu be-560mm × 560mm × 60mm, uhlobo lwe-v-uhlobo lwe-chemical fiber dense ukusonga, njengoko kubonisiwe kwi-Figure 3.

1.3 IiMfuno zoVavanyo
Ngokungqinelana nemimiselo echaphazelekayo ye-GB/T 14295-2008 “Isihluzi soMoya”, ukongeza kwiimeko zovavanyo ezifunekayo kwimigangatho yovavanyo, le miqathango ilandelayo kufuneka ifakwe:
1) Ngexesha lovavanyo, iqondo lokushisa kunye nomswakama womoya ococekileyo othunyelwa kwi-duct system kufuneka ifane;
2) Umthombo wothuli osetyenziselwa ukuvavanya zonke iisampuli kufuneka uhlale ufana.
3) Ngaphambi kokuba isampuli nganye ihlolwe, iinqununu zothuli ezifakwe kwisistim sombhobho kufuneka zicocwe ngebrashi;
4) Ukurekhoda iiyure zokusebenza zesihluzi ngexesha lovavanyo, kubandakanywa nexesha lokukhutshwa kunye nokumiswa kothuli;
2. Iziphumo zovavanyo kunye nohlalutyo
2.1 Ukutshintsha koKunyangwa kokuqala kunye noMqulu woMoya
Uvavanyo lokuqala lokuchasana lwenziwa kumthamo womoya we-80,140,220,300,380,460,540,600,711,948 m3 / h.
Ukutshintsha kokuchasana kokuqala kunye nomthamo womoya kuboniswe kwi-FIG. 4.

2.2 UTshintsho lokuSebenza ngokuLungileyo kunye noMyinge wothuli oluqokelelweyo.
Esi sicatshulwa ikakhulu sifunda ukusebenza kakuhle kokucoca kwe-PM2.5 ngokwemigangatho yovavanyo lwabavelisi, umthamo womoya olinganisiweyo wesihluzo yi-508m3/h. Amaxabiso alinganisiweyo okusebenza kakuhle kwezihluzo ezithathu phantsi kothuli olwahlukileyo lwesixa sokubeka aboniswe kwiThebhile 1
Itheyibhile 1 Ukutshintsha kokubanjwa kunye nesixa sothuli olufakiweyo
Umlinganiselo wobunzima obulinganisiweyo (ukubamba) isalathiso sezihluzo ezithathu phantsi kwexabiso lokubeka uthuli olwahlukileyo liboniswe kwiThebhile yoku-1
2.3 Ubudlelwane phakathi koKuchasa kunye nokuFumana kothuli
Isihluzo ngasinye sasetyenziselwa amaxesha ali-9 okukhupha uthuli. Amaxesha okuqala angama-7 okukhutshwa kothuli olulodwa alawulwa malunga ne-15.0g, kwaye amaxesha ama-2 okugqibela okukhutshwa kothuli olulodwa alawulwa malunga ne-30.0g.
Ukwahlukahlukana kothuli olubambe utshintsho oluchasayo kunye nomlinganiselo wokuqokelela uthuli lwezihlungi ezintathu phantsi kwe-airflow elinganisiweyo, iboniswe kwi-FIG.5

3. Uhlalutyo lwezoQoqosho lokuSetyenziswa kweSihluzo
3.1 Ubomi beNkonzo obulinganisiweyo
I-GB / T 14295-2008 "Isihluzo soMoya" sichaza ukuba xa isihluzo sisebenza kumthamo womoya olinganisiweyo kwaye ukuchasana kokugqibela kufikelela kumaxesha angama-2 okuchasana kokuqala, isihluzo sithathwa ukuba sifikelele kubomi baso benkonzo, kwaye isihluzo kufuneka sitshintshwe. Emva kokubala ubomi benkonzo yezihluzi phantsi kweemeko zokusebenza ezilinganisiweyo kolu vavanyo, iziphumo zibonisa ukuba ubomi benkonzo yezi zihluzo zintathu buqikelelwa ukuba yi-1674, 1650 kunye ne-1518h ngokulandelanayo, ngokulandelanayo kwi-3.4, 3.3 kunye ne-1 inyanga.
3.2 Uhlalutyo lokuSetyenziswa komgubo
Uvavanyo oluphindayo olungentla lubonisa ukuba ukusebenza kwezihluzo ezithathu kuyahambelana, ngoko ke isihluzo soku-1 sithathwa njengomzekelo wohlalutyo lokusetyenziswa kwamandla.
IKHIWANE. 6 Ubudlelwane phakathi kwentlawulo yombane kunye neentsuku zokusetyenziswa kwesihluzi (umthamo womoya 508m3/h)
Njengoko ixabiso lokutshintshwa komthamo womoya litshintsha kakhulu, isixa sesihluzo ekutshintsheni nasekusetyenzisweni kwamandla sitshintsha kakhulu, ngenxa yokusebenza kwesihluzi, njengoko kubonisiwe kwiFIG. 7. Kumzobo, ixabiso elibanzi = iindleko zombane osebenzayo + iyunithi yeendleko zokutshintsha umthamo womoya.
IKHIWANE. 7
Izigqibo
I-1) Ubomi benkonzo yangempela yezihlungi ezinomthamo omncinci womoya kwizakhiwo zoluntu jikelele ziphezulu kakhulu kunobomi benkonzo obuchazwe kwi-GB / T 14295-2008 "Isihluzo somoya" kwaye sinconywa ngabavelisi bangoku. Ubomi benkonzo yokwenene yesihluzi bunokuqwalaselwa ngokusekelwe kumthetho oguqukayo wokusetyenziswa kwamandla okucoca kunye neendleko zokutshintshwa.
2) Indlela yokuvavanya indawo yesihluzi esekwe kuqwalaselo lwezoqoqosho iyandululwa, oko kukuthi, ixabiso lokutshintshwa ngokomthamo womoya weyunithi nganye kunye nokusetyenziswa kwamandla okusebenza kufuneka kuqwalaselwe ngokubanzi ukumisela ixesha lokutshintshwa kwesihluzo.
