Chii chinonzi Scraped Surface Heat Exchanger?

Chinotsiviwa chekupisa pamusoro chakakweshwa: musimboti, mashandisirwo azvo uye kukura kwazvino

Chinotsikisa kupisa pamusoro chakakweshwa rudzi rwechishandiso chinotsikisa kupisa chinoshanda zvakanaka, chinoita basa rakakosha mumabasa ezvekudya, makemikari, mishonga nedzimwe nzvimbo. Kuburikidza nechimiro chakasiyana chemakanika uye mashandiro, rudzi urwu rwechinotsikisa kupisa runogadzirisa dambudziko rechinyakare chinotsikisa kupisa mukubata nekusimba kwakanyanya uye zvinhu zviri nyore kuyera. Pepa iri richaongorora zvizere chinotsikisa kupisa, chishandiso chakakosha cheindasitiri, kubva pamipimo yekushanda, hunhu hwechivakwa, minda yekushandisa uye mafambiro ekuvandudza mune ramangwana.

 Chekutanga, musimboti wekushanda uye chimiro chemuchina wekupisa wakakweshwa pamusoro

Pfungwa huru yekushanda kwemuchina wekupisa wakakweshwa ndeyekugara uchikwesha nzvimbo yekutsinhana kupisa nekutenderedza muchina wekupisa kuti uwane kutamiswa kwekupisa kwakanaka. Chimiro chikuru chinosanganisira muviri we cylindrical heat exchanger, mushave unotenderera, muunganidzwa wemuchina wekupisa, mudziyo wekutyaira uye sisitimu yekuvhara. Muviri wemuchina wekupisa unowanzova nechimiro chezvikamu zviviri, uye nzvimbo yekupisa kana yekutonhodza inopfuudzwa pakati. Muchina wekupisa wakashongedzerwa nema scrapers akawanda, ari pedyo nemadziro emukati me silinda pasi pesimba re centrifugal uye anogara achikwesha nzvimbo yekutsinhana kupisa nekutenderera kwemuchina.

 Munguva yekushanda, zvinhu zvinofanira kugadziriswa zvinopinda muheat exchanger kubva pamusoro uye zvinoyerera zvichidzika nemadziro emukati mesilinda pasi pesimba regiravhiti. Chikwenya chinotenderera hachingoiti basa rekusanganisa chete, asi chinonyanya kukosha, chinogadzirisa firimu rezvinhu zviri pamusoro peheat transfer kudzivirira zvinhu kuti zvisabatike kana kukwira pamusoro peheat temperature. Iyi dynamic film renewalization mechanism inobvumira scraped heat exchangers kuti iwane high heat transfer efficiency, kazhinji kusvika katatu kusvika kashanu pane zvemazuva ano heat exchangers.

 Chinhu chikuru chemuchina wekukwenya kupisa pamusoro pechinhu chakakwenya isystem yekukwenya, iyo dhizaini yayo inokanganisa zvakananga mashandiro emidziyo. Michina yekukwenya kupisa pamusoro pechinhu yakakwenya inoshandisa chikwenya chinogadziriswa, kuburikidza nesimba rechitubu kana repakati kuti igadzirise kumanikidzwa kwekubatana pakati pechikwenya nemadziro esirinda, kwete kungovimbisa chete kuti chinokwenya zvakanaka, asiwo kudzivirira kupfeka zvakanyanya. Sisitimu yekuvharira chikamu chakakoshawo, zvese kudzivirira kubuda kwechinhu, asiwo kuona kuti mubato unotenderera unoshanda zvakanaka.

 

Chechipiri, mabhenefiti ehunyanzvi uye miganhu ye scraped surface heat exchanger

Chinhu chakakosha zvikuru chemuchina wekupisa wekukwesha moto ndiko kugona kwawo kubata zvinhu zvinopisa zvakanyanya uye zvinonzwa kupisa. Mubasa rekugadzira chikafu, zvakaita sekugadzira puff pastry margarine, chokoreti, jamu, chizi nezvimwe zvigadzirwa, muchina wekupisa wekare wakaoma kusangana nezvinodiwa zvemaitiro acho, uye muchina wekupisa wekukwesha moto unogona kugadzirisa matambudziko aya zvakakwana. Chiyero chayo chekupisa chinogona kusvika 2000-5000W/(m²·K), chakakwirira zvikuru kupfuura muchina wekupisa weshell nechubhu.

 

Pakushandisa zvinhu zviri nyore kuyera, mabhenefiti echinochinja kupisa che scraper anonyanya kuoneka. Muindasitiri ye petrochemical, mafuta anorema, asphalt nezvimwe zvinhu zviri nyore kubikwa pamusoro pekupisa panguva yekupisa, uye chinyakare chinochinja kupisa chinoda nguva yakawanda yekuchenesa. Chinochinja kupisa che scraper kuburikidza nemhedzisiro yekukwenya inoenderera mberi, chinodzivirira chiitiko chekukwenya, chinowedzera zvakanyanya nguva yekushanda inoenderera mberi.

 

Zvisinei, ma "scraper" anotsinhana kupisa pamusoro pechinhu ane zvimwe zvipingamupinyi. Chekutanga mutengo wepamusoro wemidziyo, nekuda kwechimiro chayo chakaoma uye zvinodiwa pakugadzirisa nemazvo, mari yekutanga yakakura kupfuura ma "heat exchanger" akajairwa. Chechipiri, mutengo wekugadzirisa wakakwira, uye "scraper" nechisimbiso zvikamu zvisingakuvadzi uye zvinoda kutsiviwa nguva nenguva. Pamusoro pezvo, kana uchibata nezvinhu zvisina kusimba zvakanyanya, zvakanakira hazvionekwe, asi zvinogona kuwedzera kushandiswa kwesimba nekuda kwekusanganiswa kwe "mechanical".

 

Chechitatu, munda wekushandisa uye kukura kweramangwana kwemuchina wekupisa wepamusoro wakakweshwa

Muindasitiri yechikafu, zvinhu zvinochinja-chinja kupisa pamusoro pechinhu zvinoshandiswa zvakanyanya mukupisa chokoreti, kuichenesa nejamu, kuisimbisa nemafuta nezvimwe zvinhu. Semuenzaniso, mukugadzira chokoreti, chinhu chacho chinofanira kudzorwa nemazvo mukati memhando yekupisa yakatarwa kuti chigadziriswe, uye chinochinja-chinja kupisa chinogona kudzora tembiricha nemazvo uye kuchinjana kwekupisa kwakafanana kuti chive nechokwadi chekuti chigadzirwa chine mhando yakanaka.

 

Mundima yeindasitiri yemakemikari, ma "scraped surface heat exchangers" anonyanya kushandiswa mukugadzira ma polymer, kupisa mafuta akawanda uye mamwe maitiro. Mukugadzira ma polymer, viscosity yezvinhu zvinoshanduka nemaitiro ekuita, izvo zvakaoma kugadzirisa kune chinyakare chekupisa, asi "scraper heat exchanger" inogona kugara ichichengetedza kutamiswa kwekupisa kwakanaka. Mukuita kwekuchenesa peturu, "scraper heat exchanger" inoshandiswa kupisa mafuta akawanda, asphalt nezvimwe zvinhu, izvo zvinogadzirisa dambudziko re "coking".

 

Mune ramangwana, kugadzirwa kwemidziyo inochinja-chinja kupisa pamusoro pechinhu kuchakura zvichienderana nehungwaru, kushanda zvakanaka uye mabasa akawanda. Panyaya yehungwaru, masensa akawanda uye masisitimu ekudzora achabatanidzwa kuti awane kutarisa panguva chaiyo uye kugadzirisa otomatiki maparamita ekushanda. Kugadzirwa kwesainzi yezvinhu kuchaunza zvinhu zvitsva zvinodzivirira kupera uye zvinodzivirira ngura uye kuwedzera hupenyu hwekushanda kwemidziyo. Pamusoro pezvo, dhizaini yemodular ichave tsika yekubatsira kuchengetedza nekusimudzira michina.

 

Semhando yemichina inoshanda zvakanaka yekutsinhana kupisa, chinodzora kupisa chinokwenya chine basa guru mukugadzirwa kwemaindasitiri emazuva ano. Nekufambira mberi kuri kuitwa tekinoroji, nzvimbo yekushandisa ichawedzerwa, uye mashandiro ayo acharamba achivandudzwa. Mune ramangwana, chinodzora kupisa chinokwenya chichaita zvakawanda mukuchengetedza simba nekuderedza kusvibiswa, kuvandudza kushanda zvakanaka kwekugadzira, uye kupa rutsigiro rwakasimba mukusimudzira kugadzirwa kwemaindasitiri.
