Scraped Surface heat exchanger: Lub hauv paus ntsiab lus, daim ntawv thov thiab kev txhim kho yav tom ntej

Lub scraped nto tshav kub exchanger yog ib yam khoom siv hluav taws xob sib pauv tau zoo, uas ua lub luag haujlwm tseem ceeb hauv zaub mov, tshuaj, tshuaj thiab lwm yam lag luam. Los ntawm cov qauv siv tshuab tshwj xeeb thiab kev ua haujlwm, hom kev sib hloov hluav taws xob no daws qhov teeb meem ntawm cov khoom siv hluav taws xob sib txawv hauv kev cuam tshuam nrog cov viscosity siab thiab cov ntaub ntawv yooj yim. Daim ntawv no yuav qhia meej txog cov khoom siv hluav taws xob hluav taws xob hluav taws xob, cov khoom siv tseem ceeb hauv kev lag luam, los ntawm cov ntsiab lus ntawm kev ua haujlwm, cov yam ntxwv ntawm cov qauv, daim ntawv thov kev lag luam thiab cov qauv kev txhim kho yav tom ntej.

 Ua ntej, lub hauv paus ntsiab lus ua hauj lwm thiab cov qauv ntawm scraped nto tshav kub exchanger

Lub hauv paus ntsiab lus ntawm kev ua haujlwm tseem ceeb ntawm cov khoom siv hluav taws xob tawg yog ua kom tsis tu ncua ntawm cov khoom siv hluav taws xob sib hloov los ntawm kev tig lub scraper kom ua tiav cov cua sov hloov mus. Cov qauv yooj yim muaj xws li cylindrical heat exchanger lub cev, rotating ncej, scraper los ua ke, tsav tsheb thiab sealing system. Lub tshav kub exchanger lub cev feem ntau yog ob txheej txheej, thiab cov cua sov los yog txias nruab nrab yog kis mus rau hauv nruab nrab. Lub rotating ncej yog txawm peem rau nrog ib tug ntau ntawm scrapers, uas yog nyob ze rau lub puab phab ntsa ntawm lub tog raj kheej nyob rau hauv qhov kev txiav txim ntawm centrifugal quab yuam thiab tsis tu ncua scrape lub tshav kub hloov lwm lub tsev nto nrog kev sib hloov ntawm ncej.

 Thaum lub sij hawm ua hauj lwm, cov khoom yuav tsum tau kho nkag mus rau hauv lub tshav kub exchanger los ntawm lub sab sauv thiab ntws mus rau hauv lub puab phab ntsa ntawm lub tog raj kheej nyob rau hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqus. Lub rotating scraper tsis tsuas yog ua lub luag haujlwm ntawm kev sib tov, tab sis tseem ceeb tshaj, niaj hnub hloov kho cov ntaub ntawv zaj duab xis ntawm cov khoom siv hluav taws xob los tiv thaiv cov khoom los ntawm coking lossis scaling ntawm qhov kub thiab txias. Qhov no dynamic film renewal mechanism tso cai rau scraped nto tshav kub exchangers kom ua tau zoo heev kub hloov efficiency, feem ntau mus txog 3-5 npaug ntawm cov pa cua sov exchangers.

 Lub hauv paus tseem ceeb ntawm cov khoom siv hluav taws xob tawg yog lub tshuab scraper, uas nws tsim ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov khoom siv. Niaj hnub nimno scraped nto tshav kub exchangers feem ntau siv adjustable scraper, los ntawm lub caij nplooj ntoos hlav los yog centrifugal quab yuam los kho cov kev sib cuag siab ntawm lub scraper thiab lub tog raj kheej phab ntsa, tsis tsuas yog kom ib tug zoo scraping nyhuv, tab sis kuj kom tsis txhob hnav ntau dhau. Lub kaw lus sealing kuj yog ib qho tseem ceeb, ob qho tib si los tiv thaiv cov khoom xau, tab sis kuj los xyuas kom meej qhov kev ua haujlwm du ntawm lub rotating ncej.

 

Thib ob, cov kev zoo thiab cov kev txwv ntawm scraped nto tshav kub exchanger

Qhov tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob hluav taws xob yog nws lub peev xwm los tuav cov khoom hnyav, cov ntaub ntawv kub-rhiab heev. Hauv kev ua zaub mov, xws li kev tsim cov puff pastry margarine, qhob noom xim kasfes, jam, cheese thiab lwm yam khoom, cov khoom siv hluav taws xob sib txawv yog qhov nyuaj rau kev ua kom tau raws li cov txheej txheem, thiab scraper heat exchanger tuaj yeem daws cov teeb meem no. Nws cov hluav taws xob hloov hluav taws xob tuaj yeem ncav cuag 2000-5000W / (m²·K), ntau dua li lub plhaub zoo tib yam thiab lub raj cua kub exchanger.

 

Thaum soj ntsuam nrog cov ntaub ntawv uas yooj yim rau scale, qhov zoo ntawm scraper tshav kub exchanger yog pom tseeb dua. Hauv kev lag luam petrochemical, cov roj hnyav, asphalt thiab lwm yam khoom siv tau yooj yim rau coking ntawm lub tshav kub hloov chaw thaum lub sij hawm cua sov, thiab cov khoom siv hluav taws xob sib txawv yuav tsum tau siv sij hawm ntau zaus los ntxuav. Lub scraper kub exchanger los ntawm kev nruam scraping nyhuv, zoo tiv thaiv lub coking phenomenon, zoo heev ncua lub sij hawm mus tas li.

 

Txawm li cas los xij, scraped nto tshav kub exchangers kuj muaj qee qhov kev txwv. Thawj yog tus nqi siab ntawm cov cuab yeej siv, vim nws cov qauv siv tshuab thiab cov txheej txheem ua tiav, cov peev txheej pib loj dua li cov khoom siv hluav taws xob zoo tib yam. Qhov thib ob, tus nqi saib xyuas yog siab dua, thiab cov scraper thiab foob yog qhov tsis zoo thiab yuav tsum tau hloov tsis tu ncua. Tsis tas li ntawd, thaum cuam tshuam nrog cov khoom siv viscosity tsawg, nws qhov zoo yog tsis pom tseeb, tab sis yuav ua rau kom muaj zog siv zog vim kev sib xyaw tshuab.

 

Thib peb, daim ntawv thov teb thiab kev txhim kho yav tom ntej ntawm scraped nto tshav kub exchanger

Hauv kev lag luam khoom noj khoom haus, scraped nto tshav kub exchangers yog dav siv nyob rau hauv chocolate tempering, jam sterilization, butter crystallization thiab lwm yam txheej txheem. Piv txwv li, nyob rau hauv zus tau tej cov qhob noom xim kasfes, cov khoom yuav tsum tau precisely tswj nyob rau hauv ib tug tshwj xeeb qhov kub thiab txias kev kho mob, thiab lub scraper tshav kub exchanger yuav ua tau kom raug kub tswj thiab uniform kub pauv los xyuas kom meej cov khoom zoo.

 

Nyob rau hauv kev lag luam tshuaj, scraped nto tshav kub exchangers yog tsuas yog siv nyob rau hauv polymer ntau lawm, hnyav roj cua sov thiab lwm yam txheej txheem. Hauv kev tsim cov khoom siv polymer, cov viscosity ntawm cov khoom hloov pauv nrog cov txheej txheem tshuaj tiv thaiv, uas yog qhov nyuaj rau kev hloov pauv mus rau cov khoom siv hluav taws xob sib txawv, tab sis cov khoom siv hluav taws xob hluav taws xob tuaj yeem ua kom muaj txiaj ntsig zoo. Nyob rau hauv cov txheej txheem ntawm cov roj av refining, lub scraper heat exchanger yog siv los ua kom sov cov roj hnyav, asphalt thiab lwm yam ntaub ntawv, uas daws cov teeb meem coking.

 

Nyob rau hauv lub neej yav tom ntej, txoj kev loj hlob ntawm scraped nto tshav kub exchangers yuav tsim nyob rau hauv cov kev taw qhia ntawm kev txawj ntse, high efficiency thiab multi-function. Nyob rau hauv cov nqe lus ntawm kev txawj ntse, ntau sensors thiab tswj systems yuav tsum ua kom tiav lub sij hawm saib xyuas thiab tsis siv neeg hloov ntawm kev khiav hauj lwm tsis. Txoj kev loj hlob ntawm cov ntaub ntawv science yuav coj cov ntaub ntawv tshiab uas yog hnav-resistant thiab corrosion-resistant thiab ntev kev pab cuam lub neej ntawm cov khoom. Tsis tas li ntawd, kev tsim qauv modular yuav dhau los ua ib qho qauv los pab txhawb kev saib xyuas thiab txhim kho cov khoom siv.

 

Raws li ib yam ntawm cov khoom siv hluav taws xob sib pauv tau zoo, scraper heat exchanger plays lub luag haujlwm hloov tsis tau hauv kev lag luam niaj hnub no. Nrog kev nce qib ntawm kev siv thev naus laus zis, nws daim ntawv thov daim teb yuav nthuav dav ntxiv, thiab nws cov kev ua tau zoo yuav txuas ntxiv txhim kho. Nyob rau hauv lub neej yav tom ntej, lub scraper tshav kub exchanger yuav ua tau ntau dua kev koom tes rau lub zog txuag thiab emission txo, txhim kho efficiency ntau lawm, thiab muab kev txhawb zog rau lub sustainable kev loj hlob ntawm industrial ntau lawm.
