Cov Khoom Siv Crystallizer Uas Siv Cov Phaj Pillow Dimple Heat Exchanger
Lub tshuab ua kom cov khoom siv hluav taws xob yaj siv lub phaj pauv cua sov tshwj xeeb (Platecoil Plate) nrog cov khoom siv cua sov lossis cov khoom siv cua txias, uas yog siv rau kev ua kom sov lossis txias sab hauv. Cov phaj pauv cua sov raug muab tso rau hauv lub txee crystallizer, cov khoom siv cua sov lossis txias maj mam ua kom cov kua dej crystallizing sov lossis txias hauv qab qhov chaw khov ntawm cov khoom yaj. Thaum kawg, cov txheej crystallizing raug tsim rau ntawm qhov chaw ntawm lub phaj pauv cua sov, nws siv cov txheej txheem "SWEATING" los tshem tawm cov khoom tsis huv thiab ntxuav cov crystals.
Cov khoom siv crystallizer static melting yog ib txoj hauv kev los ntxuav thiab cais cov khoom lag luam los ntawm lwm cov khoom siv los ntawm kev siv lawv cov ntsiab lus melting sib txawv (crystallization point), thiab kom ua tiav crystallization thiab sib cais los ntawm kev txias kom ua tiav lub xeev supersaturated, Tag nrho cov txheej txheem yog muab faib ua peb kauj ruam tseem ceeb uas suav nrog crystallization, hws thiab yaj.
Cov khoom sib tov uas yaj lawm maj mam txias los ntawm cov cua sov hloov mus rau hauv qab qhov crystallization point thiab cov crystals precipitate rau ntawm qhov chaw ntawm Platecoil plates, tsim cov txheej crystallization. Cov impurities feem ntau muaj nyob rau hauv cov kua txiv hmab txiv ntoo thiab raug tso tawm ntawm crystallizer.
Cov txheej crystallization tuaj yeem ntxuav tau los ntawm kev hws (ib feem yaj), piv txwv li qeeb qeeb cua sov mus rau qhov melting point, tom qab ntawd cov khoom tsis huv thiab cov khoom lo yuav raug ntxuav los ntawm kev yaj cov khoom. Kev hws yog ib kauj ruam tseem ceeb hauv tag nrho cov txheej txheem.
Tom qab tawm hws, qhov kub ntawm qhov nruab nrab hloov pauv cua sov tau nce ntxiv kom yaj tag nrho cov txheej crystallization thiab tau txais cov khoom ua kua purity siab.
Phaj Platecoil yog ib lub tshuab hloov cua sov tshwj xeeb nrog lub phaj tiaj tiaj, tsim los ntawm kev siv tshuab laser vuam thiab inflated, nrog cov dej ntws sab hauv uas muaj zog heev, ua rau muaj kev hloov pauv cua sov siab thiab kev faib tawm kub sib xws. Nws tuaj yeem tsim thiab tsim ua ntau yam duab thiab qhov ntau thiab tsawg raws li cov neeg siv khoom xav tau. Phaj Platecoil muab tso rau hauv lub thawv muaj zog siab. Cov thev naus laus zis no ua ke nrog kev tsim qauv tiv thaiv kev sib tsoo nrog cov thev naus laus zis tsis muaj qhov chaw tuag hauv qab. Sab nraud ntawm Phaj Platecoil phaj solvent-free crystallizer (Static melting crystallizer) yog lub txee uas tsim nrog cov khoom nkag, qhov chaw tawm, qhov cua tawm, qhov chaw hla, cov cuab yeej thiab lwm yam nozzles ua haujlwm.
