Kodi Pali Kusiyana Kotani Pakati pa Cross-Flow Cooling Towers ndi Counter-Flow Cooling Towers?

 

Pankhani yamayendedwe oyenda, mu akauntala-nsanja yozizirira yoyenda,madzi ozizira amagwera vertically kuchokera pamwamba kugawa madzi dongosolo, pamene mpweya umayenda mmwamba kuchokera mpweya zolowera pansi pa nsanja. Ma TV awiriwa amalumikizana m'njira zopingasa, zomwe zimapangitsa kuti pakhale njira yayitali komanso yokwanira yosinthira kutentha. Mu across-flow cooling tower, madzi ozizira amagweranso choongoka, koma mpweya umalowa mopingasa kuchokera kumbali zonse ziwiri za nsanjayo ndikulumikizana ndi madziwo podutsa njira yopingasa. Njira yosinthira kutentha imakhala ngati "kusesa kopingasa" pamwamba pa kudzaza.

 

 

Pankhani ya kamangidwe kake, makina ogawa madzi a kauntala-chinsanja chozizira chotuluka chili pamwamba pa nsanjayo, ndi beseni losonkhanitsira pansi molunjika. Palibe chifukwa choyikira zida zapadera zamadzi amphepo, zomwe zimapangitsa kuti kamangidwe kake kamakhala kocheperako komanso kukhala ndi malo ang'onoang'ono. Komabe, kudzazidwa kwake kuyenera kupirira kukhudzidwa kwapawiri kwa kayendedwe ka madzi ndi kayendedwe ka mpweya, zomwe zimapangitsa kuti pakhale zofunikira zapamwamba pa mphamvu zakuthupi. Dongosolo logawa madzi la mtanda-nsanja yozizirira yoyenda nthawi zambiri imapangidwa ngati mbiya yam'mbali, ndipo zodzaza zimakonzedwa motsatana. Kapangidwe kameneka kamapangitsa kuti mpweya usavutike kwambiri, ndipo-mawindo akuluakulu olowera mpweya amatha kuikidwa m'mbali mwa nsanja, zomwe zimapangitsa kuti mpweya wabwino ukhale wabwino. Komabe, kuti madontho amadzi asatuluke ndi kutuluka kwa mpweya wopingasa, zigawo zingapo za zopotoka zamadzi ziyenera kuwonjezeredwa, zomwe zimatsogolera kumtunda wonse komanso malo okulirapo.

 

 

 

Malinga ndi momwe zimagwirira ntchito komanso momwe zimagwiritsidwira ntchito, zowerengera{0}}zozizira zotuluka zimapatsa mphamvu zosinthira kutentha. Pansi pa katundu wozizira womwewo, amakhala ndi voliyumu yaying'ono, ndipo kusiyana kwa kutentha kwa madzi ozizira kumatha kufika madigiri 5-10. Ndizoyenera zochitika zamafakitale zomwe zimakhala ndi zofunika kwambiri pakuzizira bwino komanso malo ochepa oyikapo, monga kukonza makina olondola, makina owongolera mpweya wapakati, ndi ma seti ang'onoang'ono a jenereta. Malo ozizira a Cross-amakhala ndi mpweya wocheperako komanso mphamvu zochepa za fan. Kuphatikiza apo, kukhuta kwawo sikungatsekeke, ndipo kukonza ndi kuyeretsa ndikosavuta. Ndioyenera makina akulu a-oyenda,{10}}akuluakulu oziziritsira madzi otsekemera, monga makina ozizirira a mafakitale azitsulo, makina opangira makemikolo, ndi malo akuluakulu opangira magetsi otentha.

 

 

Kuphatikiza apo, pali kusiyana kwamitengo ya O&M yamitundu iwiriyi. Ogawa madzi a kauntala-nsanja zoziziritsa zoyenda zimakonda kutsekeka ndipo amafunikira kuphwanyidwa ndi kuyeretsedwa nthawi zonse, ndipo mtengo wokonzanso ndi wokwera kwambiri. Mawindo olowetsa mpweya wam'mbali ndi zodzaza-zinsanja zoziziritsa zoyenda zimatha kusamalidwa mwachindunji kuchokera kunja, zomwe zimapangitsa kuti zikhale zovuta kukonza bwino ndikuzipangitsa kuti zikhale zoyenera kwa nthawi yayitali{4}}zogwira ntchito mosalekeza.

 

 

Mwachidule, posankha mtundu, choyambirira chiyenera kuperekedwa ku katundu wozizirira, malo oyikapo, mikhalidwe yamadzi, ndi mtengo wa O&M:sankhani kauntala-mtundu wa mayendedwe ang'onoang'ono-ofuna malo ang'onoang'ono, apamwamba{2}}ozizirira bwino; sankhani mtundu wodutsa-mtundu wa mayendedwe amphamvu-othamanga, okwera-opanda mpweya, ndi otsika-amphamvu{7}}zofunikira kuti muzigwiritsa ntchito.
