Contemporary Amperex Technology Co., Limited (CATL)  , wanda ke cikin ƙaramin masu amfani da EV bateri a duniya, yana amfani da gigafactory mai ƙarfi don samun lithium-ion cells. Sistamin compressed air na jihar ya kashe ƙarfin kamar 340 m³/min (20,400 m³/h)  , don tabbatar da:

• Kofin kuɗin electrode (dew point ≤ -40°C ita ce manta)
• Kilomita mai yawa na kudin gaskiya na kudin gaskiya
• Kudin gaskiya na kudin gaskiya na kudin gaskiya kuma kudin gaskiya na kudin gaskiya

Tsarin kudin gaskiya na kudin gaskiya ya sa kudin gaskiya a cikin kudin gaskiya da kudin gaskiya, saboda yanzu na kudin gaskiya da kudin gaskiya da kudin gaskiya. Almakam ya saba kudin gaskiya a cikin kudin gaskiya hudu kudin gaskiya na kudin gaskiya (micro-heat) na kudin gaskiya , wanda kowane ya kasance 85 m³/min – wani abu da aka amfani da shi sosai a cikin kudin gaskiya na kudin gaskiya kafin kudin gaskiya na kudin gaskiya na kudin gaskiya ya zama mai kyau.

Matsaloli da suka daga cikin tsari

Wadannan kudin gaskiya na kudin gaskiya kudin gaskiya na kudin gaskiya  (wanda aka kira su kudin gaskiya na kudin gaskiya ko kudin gaskiya na kudin gaskiya da kudin gaskiya) suka kawo wasu abubuwan da suka kawo alama da kudin gaskiya:

• Kudin gaskiya da kudin gaskiya da kudin gaskiya:  Kurkure na kafa da sauyi suna yanka 5–8% na ƙarfi na bayani  don gudunmawa – tare da kafin elektriki. Don hudu na 85 m³/min na kafin da suka yi a cikin karama (ƙarfi ta kowane ~300–340 m³/min), wannan yana nufin ~20 m³/min na hawayin kafa da sauyi da aka kafa da su a cikin gaba  zuwa gaba.
• Yankin Elektriki Mai Tsawo:  Kullum kafin ya bukata kafin elektriki (ta yawa 15–25 kW) a lokacin gudunmawa, wanda ya zama babban abu na yankin elektriki.
• Kuskuren Yankin Gishiri A Lokacin Karama:  A rabi, yankin gishiri mai tsawo da kuskarin yankin gishiri suna bincika gudunmawa. Yankin gishiri yayi kadan karuwa daga -35°C , wanda ke haifar da damuwa a cikin kulawar ɗaki mai bushe.

CATL ya bukaci wani ba tare da tsarkakewa ba, maganin bushewa mai aminci  da sassa masu ruwa da bakin karfe  don kawar da haɗarin lalata, da kuma ikon haɓaka don layin samarwa na gaba.

Me ya sa ba za a iya amfani da na'urar da ake amfani da ita wajen matse abubuwa ba?

Yanzu kuma, suka nuna cewa HOC dryers suna ba da zero purge kuma zero electrical heating, amma suna bukatar cewa temperature na discharge na upstream compressor ya zama ta hanyar tsakanin 120°C. CATL’s existing oil-free screw compressors, wanda suka kashe a yanzu, suna aiki a variable loads kuma kadara suna discharge a baya 100°C a lokacin da demand ya dace. HOC zai bukatar ƙarin input na heat ko bypass control, wanda zai zama mai yawa. Maki ya so a gaba daya na blower purge da aka bayyana  wanda ke aiki ta hanyar sarrafa daga load variations na compressor.

Amsunmu

Mu ka gano cewa mu saita daga uku na existing heated purge dryers da daga uku na stainless steel blower purge adsorption dryers  – wanda kowanne ya kashe 85 m³/min (5100 m³/h)  , da aka saita a parallel (uku suna aiki, uku suna kari). System ya amfani da heated ambient air don regeneration  ta hanyar zero compressed air purge loss.

Ayyukan Masu Mahimmanci

• Matsayin kafin kafa:  Hudu BlowerDry-HRB-850GRD  kukurkurun da suka yi amfani da tsarin kuskure, wanda kowane shine yana da 85 m³/min na kudin hanyar gaskiya. Duk abubuwan da suka yi amfani da hanyar gaskiya (tawarun, kwayoyin hanyar gaskiya, kankanan) suna 304 stainless steel  – ya cire rashi kuma ya tabbataci cikakken kuskuren da ke cikin tattalin arziki/kuskuren da ke cikin batiri.
• Tarihin Tafarka:  Kuskuren da ke da kyau yana ci gaskiya daga gida, yana kara shi a cikin kuskuren da ke da kudin elektriku (yana kara yadda ta zama 150–200°C ), kuma yana kuskurewa tawarun da ba suke amfani da shi. Gaskiya da ke da rashi yana cirewa. Ba a amfani da gaskiya mai kuskure daga shagaran gaskiya  – ba a samu karamin fuskanci. Tsokaci ta yi da ƙarfi na hawayen gida ta amfani da madaidaicin yadda ake amfani da shi kuma da madaidaicin yadda ake amfani da shi.
• Sisitem na Tsarin:  PLC mai tsaro (Siemens S7-1500) ya sao kadan da suka daga biyu, ya kara zaman lafiya da ya canza madaidaicin yadda ake amfani da shi lokacin da madaidaicin yadda ake amfani da shi ya ci gaba da zaman lafiya. Tsokaci na yadda ake amfani da shi (≤ -40°C) da alama na karamin fuskanci a cikin DCS na CATL.
• Tsokaci:  Madaidaicin yadda ake amfani da shi (1 µm) suka cire karamin fuskanci na karamin fuskanci; madaidaicin yadda ake amfani da shi (0.01 µm) suka cire karamin fuskanci na madaidaicin yadda ake amfani da shi. Ba a bukata madaidaicin yadda ake amfani da shi (madaidaicin yadda ake amfani da shi a wajen madaidaicin yadda ake amfani da shi).

Nemun Da Neman (12 watan bayan haɗa da tattaunawa)

*Za a buƙata 20 m³/min na hawa mai shiga don purge loss. Kuma ƙarfi na gaba ga oil-free screw compressors ita ce 6 kW per m³/min → 120 kW na ƙarfi na compressor ta faru.

Gudanin Bayanai

• Ajiyar Elektiri:  Kuƙa kusantar da fuskantar da yawa ta saba shi ne ya kawo ~120 kW na gurara gurara. Kusantar da yawa na heater da blower suka taimaka kuma. Kullum yadda ake sanya kudin elektrisitin da aka rarraba: ≈¥520,000 (ta hanyar ¥0.70/kWh, 24/7/365).
• Kamalinsa Na Produksi:  Dew point ba ta ziyarci -40°C ba. Tsarin kula na dry room ya zama mai tsayi da dacewa, kuma ba a bayani da wani abu na kuskure na coating da ke daya da ruwan ba.
• Kusantar da Yawa Na Contamination:  Tawarar stainless steel da pipes sun kusantar da yawa na kuskure na rust particles. Filters na gaba daya sun nuna ba wani contamination na iron oxide ba – wanda ke muce babban ingantaccen bateri.
• Kusantar da Yawa Na Maintenance:  Ba a amfani da purge valves na high-cycle ba (masu gurara na farko sun amfani da valves da suka cikin ƙaramin 1–2 saati). Blower purge dryers sun amfani da biyu saja mai muhimmi per tower da suka cikin ƙaramin 6–8 saati. Desiccant attrition ya kashe kamar yawa.
• Redundancy & Scalability:  Daga cikin hudu ƙarama (3+1), CATL zai iya yin sauyin kuma gudanen kowane maita ba tare iyalin sarakuna. Karamar da ke baya kuma zai iya gudanen kewayen da suka zuwa a yanzu.
• ROI:  Kasa ta yau da kullum ≈ ¥2,400,000. Karamin da aka rage a watan (kuma karamin yadda ake amfani da hawaye + sauyin) ≈ ¥520,000 + ¥170,000 = ¥690,000. Wata na sauyin bayani ≈ 3.5 shekara . CATL ya saita wannan tsari don wasu kasuwa.
