Kompresa wa CO2 wapamwamba kwambiri

 

 

Ndikofunikira kwambiri kusankha compressor ya CO2 yapamwamba kwambiri. Mukasankha compressor yoyenera, mutha kuigwiritsa ntchito popanga chinthu chabwino kwambiri kuti mupeze phindu lalikulu.

 

Zofunika Kwambiri:

 

Mfundo ya CO2 compressor

 

Zabwino kwambiri za ma compressor a CO2

 

Kugwiritsa ntchito bwino kwambiri kwa ma compressor a CO2

 

Mfundo ya CO2 compressor
Kuchokera ku makampani ogwiritsira ntchito ma compressor, mafakitale omwe amagwiritsidwa ntchito popanga mpweya wopanikizika ndi monga makina, magalimoto, zamagetsi, mphamvu zamagetsi, zitsulo, migodi, zomangamanga, zipangizo zomangira, mafuta, mankhwala, petrochemical, nsalu, kuteteza zachilengedwe, zankhondo ndi zina zamafakitale ndi zachitukuko. Madera onse opanga ndi moyo. Mpweya wopanikizika ndi gwero lofunikira la mphamvu pazinthu zamafakitale, ndipo umadziwikanso kuti "gwero la moyo" popanga zinthu zamafakitale.

 

Pali mitundu yambiri ya ma compressor a mpweya, omwe angagawidwe m'magulu atatu kutengera momwe amagwirira ntchito: volumetric, dynamic (speed kapena turbo) ndi thermal. Mu ma compressor osinthasintha bwino, kuwonjezeka kwa kuthamanga kumachitika podalira kukanikiza mwachindunji kwa voliyumu ya mpweya. Mu compressor yoyendetsedwa ndi mphamvu, impeller imazungulira mwachangu kuti iwonjezere kuthamanga ndi liwiro la mpweya, kenako mu chinthu chosasuntha, gawo la liwiro likhoza kusinthidwa kukhala mphamvu ya kuthamanga kwa mpweya. Jet ndi chosindikizira cha kutentha. Imagwiritsa ntchito mpweya wothamanga kwambiri kapena jet ya nthunzi kunyamula mpweya woyenda mkati, womwe umasinthidwa kukhala mphamvu ya kuthamanga pa liwiro la chisakanizo chofalikira.

 

Zabwino kwambiri za ma compressor a CO2
Poyerekeza ndi ma compressor wamba oziziritsa, ma compressor a CO2 ali ndi kuthamanga kwambiri kwa ntchito, kuthamanga kwakukulu kosiyana, kupanikizika pang'ono, kuchuluka kochepa, kulemera kopepuka, kuvutika kuwongolera kutseguka kwa ziwalo zoyenda, komanso mawonekedwe ovuta a mafuta. Chifukwa chake, kafukufuku ndi chitukuko cha ma compressor a carbon dioxide nthawi zonse akhala ovuta pakupanga ukadaulo wa firiji. Mabungwe osiyanasiyana ofufuza ndi makampani ogwiritsira ntchito zida zoziziritsira apanga mitundu yosiyanasiyana ya ma compressor kunyumba ndi kunja. Chifukwa cha ubwino wa CO2 pakugwiritsa ntchito mpweya woziziritsa m'magalimoto, ma compressor a mpweya woziziritsa m'magalimoto a CO2 nawonso aphunziridwa ndikupangidwa kudzera m'makampani osiyanasiyana oziziritsa m'magalimoto ndi makampani ogulitsa magalimoto.

 

Kugwiritsa ntchito bwino kwambiri kwa ma compressor a CO2
1. Pakugwiritsa ntchito mpweya woziziritsa m'magalimoto, panthawiyi, makina oziziritsa m'magalimoto amagwiritsidwa ntchito pansi pa mikhalidwe yosinthasintha, ndipo kuthamanga kwake kogwira ntchito ndi kwakukulu koma chiŵerengero cha kupsinjika ndi chochepa, mphamvu ya compressor ndi yayikulu; kusamutsa kutentha kwabwino kwambiri komanso mphamvu ya thermodynamic ya madzi ofunikira kwambiri zimapangitsa kuti ikhale yogwira ntchito bwino. Mphamvu yokhala chosinthira kutentha nayonso ndi yayikulu kwambiri, zomwe zimapangitsa makina oziziritsa m'magalimoto kukhala ogwira ntchito bwino komanso amatha kupikisana ndi ma refrigerant wamba (monga R12, R22, ndi zina zotero) ndi njira zina zomwe zilipo (R134a, R410A, ndi zina zotero). Pakupanga magalimoto amagetsi, mawonekedwe a mapampu otenthetsera a carbon dioxide amathanso kuthetsa vuto lakuti makina oziziritsa m'magalimoto amakono sangathe kupereka kutentha kokwanira kugalimoto nthawi yozizira. Kudzera mu maphunziro ambiri oyesera, zawonetsedwa kuti kayendedwe ka CO2 ka makina oziziritsa m'magalimoto sikuti kokha kali ndi ubwino wa chilengedwe, komanso kumakhudza magwiridwe antchito.

 

2. Yogwiritsidwa ntchito pa mapampu osiyanasiyana otenthetsera, makamaka zotenthetsera madzi za pampu yotenthetsera. Pakadali pano, makina otenthetsera a pampu yotenthetsera amagwiranso ntchito pansi pa mikhalidwe yovuta kwambiri, ndipo ubwino wa compressor ndi chosinthira kutentha ulipobe; kusintha kwakukulu mu CO2 yoziziritsira mpweya ndi koyenera kutentha madzi, motero kumapangitsa kuti pampu yotenthetsera ikhale yogwira mtima kwambiri, ndipo imatha kupikisana ndi ma refrigerant wamba (R134a, R410A, ndi zina zotero). Pophunzira pampu yotenthetsera ya CO2, sikuti kutulutsa kwa CO2 kokha kungachepe, komanso pampu yotenthetsera ili ndi magwiridwe antchito ambiri ndipo ili ndi mwayi wogwiritsa ntchito komanso kukulitsa.

 

3. Kugwiritsa ntchito mu makina oziziritsira a cascade. Pakadali pano, CO2 imagwiritsidwa ntchito ngati firiji yotsika kutentha, ndipo kutentha kwakukulu kumapangidwa ndi NH3 kapena R290 ngati firiji. Poyerekeza ndi mafiriji ena a cryogenic, ngakhale kutentha kochepa, CO2 ili ndi kukhuthala kochepa kwambiri, mphamvu yabwino yosamutsira kutentha, komanso mphamvu yayikulu yozizira.

Pakadali pano, ku China, makina oziziritsira a NH/CO2 cascade, ndi NH3 ngati firiji, CO2 ngati makina oziziritsira oziziritsira akhala akugwiritsidwa ntchito kwambiri mu uinjiniya wa mayendedwe, kukonza nkhuku, kupanga ayezi, zosakaniza zoziziritsira ndi kugwiritsa ntchito zinthu zam'madzi.
