Ngenxa yesithwathwa ebusweni be-evaporator endaweni yokugcina ebandayo, ivimbela ukuqhutshwa nokusabalalisa umthamo obandayo we-evaporator yesiqandisi (ipayipi), futhi ekugcineni ithinte umphumela wesiqandisi. Lapho ubukhulu bengqimba yesithwathwa (iqhwa) ebusweni be-evaporator bufinyelela izinga elithile, ukusebenza kahle kwesiqandisi kuze kwehle kuze kube ngaphansi kuka-30%, okuholela ekumosheni okukhulu kwamandla kagesi futhi kufinyeze impilo yesevisi yesistimu yesiqandisi. Ngakho-ke, kuyadingeka ukwenza umsebenzi wokunciphisa isitoreji esibandayo emjikelezweni ofanele.
Inhloso yokuqeda iqhwa
1, ukuthuthukisa ukusebenza kahle kwesiqandisi sohlelo;
2. Qinisekisa ikhwalithi yemikhiqizo eqandisiwe endaweni yokugcina impahla
3, yonga amandla;
4, nwebisa impilo yesevisi yesistimu yokugcina okubandayo.
Indlela yokuqeda iqhwa
Izindlela zokuqeda isithwathwa endaweni ebandayo: igesi eshisayo yokuncibilika (i-hot fluorine defrosting, i-hot ammonia defrosting), i-water defrosting, i-electrical defrosting, i-mechanical (yokwenziwa) iqhwa, njll.
1, igesi eshisayo defrost
Ifanele ipayipi elikhulu, eliphakathi nendawo nelincane lokugcina elibandayo elincibilikisa ngqo izinga lokushisa eliphezulu elishisayo legesi elijiya lingene kusishuphuki ngaphandle kokumisa ukugeleza, izinga lokushisa elihwamuzayo liyakhuphuka, futhi ungqimba lwesithwathwa kanye nejoyinti lokuphuma okubandayo liyancibilika noma bese liyaxebuka. I-hot gas defrosting iyonga futhi inokwethenjelwa, ilungele ukugcinwa nokuphathwa, futhi ubunzima bayo bokutshala izimali nokwakha abukhulu. Kodwa-ke, kukhona nezinhlelo eziningi zokuqeda igesi eshisayo, umkhuba ojwayelekile ukuthumela igesi enomfutho ophezulu kanye nokushisa okuphezulu ekhishwa ku-compressor ibe yi-evaporator ukuze ikhulule ukushisa nokuncibilika, ukuze uketshezi olujiyile lube selungena kwenye i-evaporator ukuze lumunce. ukushisa nokuhwamuka kumazinga okushisa aphansi kanye negesi enengcindezi ephansi, bese ibuyela ku-compressor suction port ukuze uqedele umjikelezo.
2, amanzi isifutho defrost
Isetshenziswa kabanzi ukuncibilikisa ama-chillers amakhulu naphakathi
Ngezikhathi ezithile fafaza i-evaporator ngamanzi okushisa kwegumbi ukuze uncibilikise ungqimba lwesithwathwa. Nakuba umphumela wokuqeda iqhwa muhle kakhulu, ulungele kakhulu okokupholisa umoya, futhi kunzima ukusebenzisa amakhoyili ahwamukayo. Kungenzeka futhi ukufafaza i-evaporator ngesisombululo esinezinga lokushisa eliphakeme lokuqandisa, njenge-5% -8% ye-concentrated brine, ukuvimbela ukwakheka kwesithwathwa.
3. Ukuncibilika kukagesi
Ukushisa kwamapayipi okushisa kagesi kusetshenziswa kakhulu endaweni epholile ephakathi nendawo encane; Izintambo zokushisisa zikagesi zisetshenziswa kakhulu kumashubhu e-aluminium okugcina amaphakathi namancane
Ukushisa okushisayo kukagesi, i-chiller ilula futhi kulula ukuyisebenzisa; Kodwa-ke, esimweni sokugcinwa okubandayo kwe-aluminium tube, ubunzima bokwakhiwa kwe-aluminium fin ukufakwa kocingo lokufudumeza kagesi abuncane, futhi izinga lokuhluleka liphezulu kakhulu esikhathini esizayo, ukugcinwa nokuphatha kunzima, umnotho umpofu, futhi isici sokuphepha siphansi uma kuqhathaniswa.
4, mechanical defrosting yokwenziwa
Amapayipi amancane okugcina abandayo ancishiswa iqhwa ukuze kuncishiswe amapayipi okugcina abandayo ngokonga kakhulu, indlela yokuqala yokuqeda iqhwa. Isitoreji esikhulu esibandayo esine-defrosting yokwenziwa akunangqondo, ukusebenza kwekhanda phezulu kunzima, ukusetshenziswa ngokomzimba kuyashesha kakhulu, isikhathi sokugcina endaweni yokugcina izinto side kakhulu siyingozi empilweni, ukuchithwa kweqhwa akulula ukuqeda, kungase kubangele ukuwohloka kwe-evaporator, futhi ingase iphule ngisho ne-evaporator futhi iholele ezingozini zokuvuza eziqandisini.
Ukukhetha imodi(Fluorine system)
Ngokusho kwe-evaporator ehlukene yesitoreji esibandayo, indlela yokunciphisa i-frosting efanele ikhethiwe, futhi ukusetshenziswa kwamandla, ukusetshenziswa kwesici sokuphepha, ubunzima bokufaka kanye nokusebenza kuyahlolwa futhi.
1, indlela yokuqeda iqhwa yefeni elibandayo
Kukhona i-electric tube defrosting kanye ne-water defrosting ingakhetha. Izindawo ezisebenziseka kalula amanzi zingancamela isithwathwa esithela amanzi, futhi izindawo ezinokuntuleka kwamanzi zivame ukukhetha ipayipi lokushisa likagesi elibandisa isithwathwa. I-water flushing frost chiller ngokuvamile ilungiswa ku-air conditioning enkulu, ohlelweni lwesiqandisi.
2. Indlela yokuqeda iqhwa yomugqa wensimbi
Kukhona i-fluorine defrosting eshisayo kanye nezinketho zokuqeda amaqhwa okwenziwa.
3. Indlela yokunciphisa ishubhu ye-aluminium
Kukhona okukhethwa kukho kwe-thermal fluoride defrosting ne-electric thermal defrosting. Ngokusetshenziswa kabanzi kwe-aluminium tube evaporator, ukuchithwa kweshubhu ye-aluminium kunakwe kakhulu ngabasebenzisi. Ngenxa yezizathu ezibonakalayo, ishubhu ye-aluminium ngokuyisisekelo ayifaneleki ukusetshenziswa kwe-artificial defrosting elula nemahhadla njengensimbi, ngakho-ke indlela yokuqeda iqhwa yeshubhu ye-aluminium kufanele ikhethe indlela yokuncibilikisa izintambo zikagesi kanye nendlela yokuncibilikisa i-fluorine eshisayo, ehlanganiswe nokusetshenziswa kwamandla, isilinganiso sokusebenza kahle kwamandla. nokuphepha nezinye izici, i-aluminium tube defrosting ifaneleka kakhulu ukukhetha indlela yokushisa i-fluorine eshisayo.
I-Hot Fluoride Defrosting Isicelo
Ithuluzi lokuguqula isiqondiso sokugeleza kwe-freon elithuthukiswe ngokomgomo wokuncibilikisa igesi eshisayo, noma uhlelo lokuguqula olwakhiwe ngamavalvu amaningi kagesi (amavalvu esandla) axhumene, okungukuthi, isiteshi sokulawula isiqandisi, angabona ukusetshenziswa kwe-hot fluorine defrosting isitoreji esibandayo.
1, isiteshi sokulungisa mathupha
Isetshenziswa kabanzi ezinhlelweni ezinkulu zesiqandisi ezifana nokuxhuma okufanayo.
2, imishini yokuguqula i-fluorine eshisayo
Isetshenziswa kakhulu ohlelweni lwesiqandisi olulodwa oluncane naphakathi. Okufana nokuthi: ukhiye owodwa we-fluorine eshisayo yokuguqula idivayisi.
Ukuchofoza okukodwa kushisa i-fluorine defrosting
Ilungele uhlelo oluzimele lokujikeleza kwe-compressor eyodwa (ayifanele ukufakwa kokuxhumeka kwamayunithi afanayo, ama-multistage kanye namayunithi agqagqene). Isetshenziswa emakhazeni amancane naphakathi nendawo yokugcina amapayipi kanye ne-ice industry defrosting.
okukhethekile
1, ukulawula okwenziwa ngesandla, ukuguqulwa kokuchofoza okukodwa.
2, ukushisa ngaphakathi, ungqimba lwesithwathwa kanye nodonga lwamapayipi lungancibilika futhi liwe, isilinganiso sokusebenza kahle kwamandla 1:2.5.
I-3, i-defrosting kahle, ngaphezu kuka-80% we-frost layer iwukwehla okuqinile.
I-4, ngokusho komdwebo ofakwe ngokuqondile kuyunithi yokunciphisa, awudingi ezinye izesekeli ezikhethekile.
5, ngokomehluko wangempela wokushisa okuzungezile, ngokuvamile kuthatha imizuzu engama-30 kuye kwayi-150.
