Scraped Surface heat exchanger: Mfundo, kugwiritsa ntchito ndi chitukuko chamtsogolo

The scraped surface heat exchanger ndi mtundu wa zida zosinthira kutentha, zomwe zimagwira ntchito yofunika kwambiri pazakudya, mankhwala, mankhwala ndi mafakitale ena. Kudzera m'makina apadera komanso mawonekedwe ogwirira ntchito, chotenthetsera chamtunduwu chimathetsa vuto lachiwongolero chachikhalidwe pothana ndi kukhuthala kwakukulu komanso zosavuta kukulitsa zida. Pepalali lisanthula mwatsatanetsatane chowotcha chotenthetsera, zida zofunika kwambiri zamafakitale, kuchokera ku mfundo zogwirira ntchito, mawonekedwe ake, magawo ogwiritsira ntchito komanso zomwe zikuchitika m'tsogolomu.

 Choyamba, mfundo yogwirira ntchito ndi mawonekedwe a chowotcha chotenthetsera chapamwamba

Mfundo yayikulu yogwirira ntchito ya chotenthetsera chapamadzi ndikukankhira mosasintha malo osinthira kutentha pozungulira chopukutira kuti chikwaniritse kutentha koyenera. Mapangidwe oyambira amaphatikizapo cylindrical heat exchanger body, shaft yozungulira, msonkhano wa scraper, chipangizo choyendetsa ndi makina osindikizira. Thupi lothandizira kutentha nthawi zambiri limakhala la magawo awiri, ndipo chotenthetsera kapena chozizira chimadutsa pakati. Mtsinje wozungulira uli ndi zida zambiri zowonongeka, zomwe zili pafupi ndi khoma lamkati la silinda pansi pa mphamvu ya centrifugal ndipo mosalekeza kupukuta pamwamba pa kutentha kwa kutentha ndi kuzungulira kwa shaft.

 Panthawi yogwira ntchito, zinthu zomwe ziyenera kuchitiridwa zimalowa m'malo otenthetsera kutentha kuchokera kumtunda ndikutsika pansi pa khoma lamkati la silinda pansi pa mphamvu yokoka. Chophimba chozungulira sichimangogwira ntchito yosakaniza, koma chofunika kwambiri, nthawi zonse chimasintha filimu yazinthu pamtunda wotentha kutentha kuti zisawonongeke kuti zisaphike kapena kukwera pamwamba pa kutentha kwakukulu. Njira yosinthira filimuyi imalola makina osinthira kutentha kuti azitha kutengera kutentha kwambiri, nthawi zambiri mpaka 3-5 kuposa momwe amatenthetsera wamba.

 Chigawo chofunika kwambiri cha kutentha kwa kutentha kwapamwamba ndi scraper system, yomwe mapangidwe ake amakhudza mwachindunji ntchito ya zipangizo. Zosintha zamakono zamakono zogwiritsira ntchito kutentha kwapamwamba zimagwiritsa ntchito scraper yosinthika, kupyolera mu kasupe kapena mphamvu ya centrifugal kuti isinthe kukhudzana kwapakati pa scraper ndi khoma la silinda, osati kuonetsetsa kuti kupukuta bwino, komanso kupewa kuvala kwambiri. Makina osindikizira nawonso ndi gawo lofunikira, poletsa kutayikira kwa zinthu, komanso kuonetsetsa kuti shaft yozungulira ikugwira ntchito bwino.

 

Chachiwiri, luso laukadaulo ndi zolephera za chowotcha chotenthetsera chapamwamba

Ubwino wofunikira kwambiri wa scraper heat exchanger ndi kuthekera kwake kogwiritsa ntchito zinthu zowoneka bwino kwambiri, zosamva kutentha. M'munda wa processing chakudya, monga kupanga puff pastry margarine, chokoleti, kupanikizana, tchizi ndi zinthu zina, chikhalidwe kutentha exchanger n'zovuta kukwaniritsa ndondomeko zofunika, ndi scraper kutentha exchanger angathe mwangwiro kuthetsa mavutowa. Mphamvu yake yotengera kutentha imatha kufika 2000-5000W/(m²·K), yokwera kwambiri kuposa chigoba wamba ndi chosinthira kutentha kwa chubu.

 

Pochita ndi zipangizo zomwe zimakhala zosavuta kukula, ubwino wa scraper heat exchanger ndi woonekeratu. M'makampani a petrochemical, mafuta olemera, asphalt ndi zida zina ndizosavuta kuziyika pamalo otenthetsera kutentha, ndipo zotenthetsera zachikhalidwe zimafunikira nthawi yocheperako kuti iyeretse. The scraper heat exchanger kudzera mosalekeza scraping zotsatira, bwino kuteteza coking phenomenon, kwambiri kumawonjezera nthawi yopitirira yothamanga.

 

Komabe, zotenthetsera zowotchera pamwamba zimakhalanso ndi malire. Yoyamba ndi kukwera mtengo kwa zida, chifukwa cha makina ake ovuta komanso zofunikira pakuwongolera moyenera, ndalama zoyambira ndizokulirapo kuposa zosinthira wamba. Kachiwiri, mtengo wokonza ndi wokwera kwambiri, ndipo scraper ndi chisindikizo ndi zida zomwe zili pachiwopsezo ndipo zimafunika kusinthidwa pafupipafupi. Kuonjezera apo, pogwira ntchito ndi zipangizo zotsika kwambiri, ubwino wake sudziwikiratu, koma ukhoza kuwonjezera mphamvu yogwiritsira ntchito mphamvu chifukwa cha kusakaniza makina.

 

Chachitatu, malo ogwiritsira ntchito ndi chitukuko chamtsogolo cha chosinthira kutentha chapamwamba

M'makampani azakudya, zotenthetsera zapamadzi zimagwiritsidwa ntchito kwambiri pakuwotcha chokoleti, kutsekereza kupanikizana, crystallization ya batala ndi njira zina. Mwachitsanzo, popanga chokoleti, zinthuzo ziyenera kuyendetsedwa bwino mkati mwa kutentha kwapadera kwa kutentha kwa kutentha, ndipo scraper heat exchanger ikhoza kukwaniritsa kutentha kolondola komanso kusinthanitsa kutentha kwa yunifolomu kuti zitsimikizire mtundu wa mankhwala.

 

M'munda wamakampani opanga mankhwala, zotenthetsera zotenthetsera pamtunda zimagwiritsidwa ntchito kwambiri popanga polima, kutentha kwamafuta olemera ndi njira zina. Popanga polima, kukhuthala kwa zinthu kumasintha ndi momwe zimachitikira, zomwe zimakhala zovuta kutengera chosinthira chachikhalidwe, koma chowotcha chowotcha chimatha kukhalabe ndi kutentha koyenera. Pokonza mafuta a petroleum, scraper heat exchanger imagwiritsidwa ntchito kutentha mafuta olemera, asphalt ndi zipangizo zina, zomwe zimathetsa vuto la kuphika.

 

M'tsogolomu, chitukuko cha makina opangira kutentha kwapamwamba chidzakula motsatira nzeru, kuchita bwino kwambiri komanso ntchito zambiri. Pankhani ya luntha, masensa ambiri ndi machitidwe owongolera adzaphatikizidwa kuti akwaniritse kuyang'anira nthawi yeniyeni ndi kusintha kwachangu kwa magawo ogwiritsira ntchito. Kukula kwa sayansi ya zida kubweretsa zida zatsopano zomwe sizitha kuvala komanso zosagwira dzimbiri ndikukulitsa moyo wautumiki wa zida. Kuphatikiza apo, mapangidwe a modular adzakhala njira yothandizira kukonza ndi kukweza zida.

 

Monga zida zosinthira kutentha, scraper heat exchanger imagwira ntchito yosasinthika pakupanga mafakitale amakono. Ndi kupita patsogolo kosalekeza kwa ukadaulo, gawo logwiritsira ntchito lidzakulitsidwanso, ndipo ntchito yake ipitilirabe bwino. M'tsogolomu, scraper heat exchanger idzathandizira kwambiri kupulumutsa mphamvu ndi kuchepetsa utsi, kupititsa patsogolo kupanga bwino, ndikupereka chithandizo champhamvu pa chitukuko chokhazikika cha kupanga mafakitale.
