Scraped Surface heat exchanger: Nheyo, kushandiswa uye kuvandudza kweramangwana

The scraped surface heat exchanger imhando yezvigadzirwa zvekugadzirisa kupisa, izvo zvinoita basa rinokosha muzvokudya, kemikari, mishonga uye mamwe maindasitiri. Kuburikidza neyakasiyana mashandiro emuchina uye maitiro ekushanda, rudzi urwu rwekupisa runogadzirisa dambudziko rechinyakare kupisa kupisa mukubata nepamusoro viscosity uye nyore kuyera zvinhu. Iri bepa richanyatsoongorora iyo scraper heat exchanger, yakakosha maindasitiri midziyo, kubva kune zvikamu zvemusimboti wekushanda, maitiro ezvimiro, minda yekushandisa uye mafambiro ebudiriro mune ramangwana.

 Chekutanga, iyo yekushanda musimboti uye chimiro cheyakaraswa pamusoro pekupisa exchanger

Musimboti wekushanda weiyo scraped surface heat exchanger ndeyekuramba uchikwenya nzvimbo yekutsinhanisa kupisa nekutenderedza iyo scraper kuti ibudirire kupisa kupisa. Chimiro chekutanga chinosanganisira cylindrical heat exchanger body, inotenderera shaft, scraper assembly, kutyaira mudziyo uye yekuisa chisimbiso. Muviri wekupisa wekupisa unowanzo kuve kaviri-layer chimiro, uye yekudziya kana kutonhora svikiro inopfuudzwa nepakati. Iyo shaft inotenderera yakashongedzerwa nehuwandu hwema scrapers, ayo ari padyo nemadziro emukati mecylinder pasi pechiito che centrifugal simba uye achiramba achitsvaira nzvimbo yekupisa kupisa nekutenderera kwe shaft.

 Munguva yekushanda, zvinhu zvinofanirwa kurapwa zvinopinda mumhepo inopisa kubva kumusoro uye inoyerera ichidzika nemadziro emukati we cylinder pasi pechiito chegiravhiti. Iyo inotenderera scraper haingoite basa rekusanganisa, asi zvinonyanya kukosha, inogara ichivandudza iyo firimu yezvinhu pamhepo yekupisa yekupisa kudzivirira kuti zvinhu zvirege kubikwa kana kuyera pamusoro pekupisa kwepamusoro. Iyi firimu ine simba yekuvandudza magadzirirwo inobvumira yakakurwa pamusoro pekushisa exchanger kuti iwane yakanyanyisa kupisa kupisa kunyatsoshanda, kazhinji kusvika ku3-5 nguva yeyakajairwa kupisa kupisa.

 Chinhu chinonyanya kukosha chekutsvaira kwekushisa kwepamusoro ndeye scraper system, iyo yakagadzirwa inobata zvakananga kushanda kwemidziyo. Mazuva ano scraped surface heat exchangers anonyanya kushandisa scraper inogadziriswa, kuburikidza nechirimo kana simba re centrifugal kugadzirisa kushandiswa kwekubatana pakati pe scraper uye cylinder wall, kwete kungoita kuti kuve nekugadzirisa kwakanaka, asiwo kudzivirira kupfeka zvakanyanya. Iyo yekuisa chisimbiso zvakare chikamu chakakosha, zvese kudzivirira kubuda kwezvinhu, asiwo kuve nechokwadi chekushanda kwakatsetseka kweshaft inotenderera.

 

Chechipiri, zvakanakira hunyanzvi uye zvisingakwanisi scraped surface heat exchanger

Kunyanya kukosha kweiyo scraper heat exchanger ndiko kugona kwayo kubata zvakanyanya viscous, kupisa-sensitive zvinhu. Mumunda wekugadzira chikafu, sekugadzirwa kwepuff pastry margarine, chokoreti, jamu, chizi uye zvimwe zvigadzirwa, iyo yechinyakare yekupisa inopisa yakaoma kuzadzisa zvinodiwa maitiro, uye scraper heat exchanger inogona kunyatsogadzirisa matambudziko aya. Chiyereso chayo chekutamisa kupisa chinogona kusvika 2000-5000W/(m²·K), yakakwira zvakanyanya kupfuura yakajairwa goko uye chubhu yekupisa yekupisa.

 

Paunenge uchibata nezvinhu zviri nyore kuyera, zvakanakira zve scraper heat exchanger zviri pachena. Muindasitiri yepetrochemical, mafuta anorema, asphalt uye zvimwe zvinhu zviri nyore kubikira panzvimbo yekupisa kupisa panguva yekudziya, uye zvechinyakare zvinopisa zvinopisa zvinoda nguva zhinji yekudzikira pakuchenesa. The scraper heat exchanger kuburikidza nekuenderera mberi kwekutsvaira, zvinodzivirira kudzivirira coking phenomenon, inowedzera zvikuru nguva inoenderera mberi.

 

Nekudaro, yakatsvairwa pamusoro pekupisa exchangers inewo zvimwe zvinogumira. Yekutanga mutengo wakakwirisa wemidziyo, nekuda kweiyo yakaoma mekiniki chimiro uye nemazvo ekugadzirisa zvinodiwa, iyo yekutanga investimendi yakakura kupfuura yakajairwa kupisa kupisa. Chechipiri, mari yekuchengetedza yakakwira, uye scraper uye chisimbiso zvikamu zvisina njodzi uye zvinoda kutsiviwa nguva dzose. Mukuwedzera, kana uchibata ne-low-viscosity zvinhu, zvikomborero zvayo hazvisi pachena, asi zvinogona kuwedzera kushandiswa kwesimba nekuda kwekusanganiswa kwemagetsi.

 

Chechitatu, nzvimbo yekushandisa uye kuvandudza kweramangwana kweyakakurwa pamusoro pekupisa exchanger

Muindasitiri yezvechikafu, yakaraswa pamusoro pekupisa kupisa inoshandiswa zvakanyanya muchokoreti tempering, jam sterilization, butter crystallization uye mamwe maitiro. Semuyenzaniso, mukugadzirwa kwechokoreti, zvinhu zvacho zvinoda kunyatso kudzorwa mukati meimwe tembiricha yemhando yekudzora tembiricha, uye scraper heat exchanger inokwanisa kuwana kwakaringana tembiricha kutonga uye yunifomu yekutsinhana kwekushisa kuve nechokwadi chemhando yechigadzirwa.

 

Mumunda weindasitiri yemakemikari, yakakandwa pamusoro pekushisa exchangers inonyanya kushandiswa mukugadzirwa kwepolymer, kupisa mafuta anorema uye mamwe maitiro. Mukugadzirwa kwepolymer, viscosity yezvinhu zvinoshanduka nemaitiro ekuita, izvo zvakaoma kuenderana neyakajairwa kupisa kupisa, asi scraper heat exchanger inogona kugara ichichengetedza yakanakira kupisa kupisa. Mukugadzirisa petroleum refining, scraper heat exchanger inoshandiswa kupisa mafuta anorema, asphalt nezvimwe zvinhu, izvo zvinogadzirisa dambudziko rekubika.

 

Mune ramangwana, kukudziridzwa kwekutsvaira kwekupisa kwepamusoro kuchavandudza munzira yehungwaru, kushanda kwepamusoro uye mabasa akawanda. Panyaya yehungwaru, mamwe ma sensors uye masisitimu ekudzora achabatanidzwa kuti awane chaiyo-nguva yekutarisa uye otomatiki kugadzirisa kweanoshanda paramita. Kuvandudzwa kwesainzi yezvishandiso kunounza zvinhu zvitsva zvinoramba kupfeka uye zvisingaite corrosion uye kuwedzera hupenyu hwebasa remidziyo. Uye zvakare, modular dhizaini inozoita maitiro ekufambisa kuchengetedza uye kukwidziridzwa kwemidziyo.

 

Semhando yemidziyo inoshanda yekutsinhanisa kupisa, scraper heat exchanger inoita basa risingadzokerike mukugadzirwa kwemazuva ano kwemaindasitiri. Nekuenderera mberi kwekuenderera mberi kwetekinoroji, nzvimbo yayo yekushandisa ichawedzerwa, uye kuita kwayo kucharamba kuchivandudza. Mune ramangwana, scraper heat exchanger ichaita mipiro yakakura mukuchengetedza simba uye kuderedza emission, kuvandudza kushanda kwekugadzira, uye kupa rubatsiro rwakasimba rwekusimudzira kugadzirwa kwemaindasitiri.
