Cov yam ntxwv tseem ceeb ntawm kev ntim khoom

2022-07-29 IB

1. Qhov kev sib cais ntawm cov txheej txheem ntim khoom yog siab, thiab qhov kev rho tawm ntawm cov pej thuam rectification yog siab.Cov pa oxygen thiab nitrogen extraction tus nqi ntawm cov cuab yeej sib cais huab cua tau muab faib ua ob hom: tus nqi rho tawm ntawm cov cuab yeej ua tiav thiab tus nqi rho tawm ntawm cov pej thuam rectification.Vim lub extraction npaum li cas ntawm cov khoom ua tiav thiab lub peev xwm ntawm cov khoom sib cais huab cua.Cov zis ntawm cov khoom ua kua muaj feem xyuam rau lwm yam.Nws yog qhov nyuaj los ntsuas qhov kev sib cais siab ntawm cov txheej txheem ntim khoom.Tus nqi rho tawm ntawm cov kab rov qab thiab qhov kev rho tawm ntawm argon tuaj yeem sawv cev zoo dua rau qib tsim ntawm huab cua sib cais cog.khoom siv sub.Cov pa oxygen rho tawm ntawm nws cov pej thuam rectification tau mus txog ntau dua 99%;argon rho tawm tus nqi tau mus txog 79%.

Kev khiav hauj lwm tus nqi ntawm cov ntsiab lus oxygen nyob rau hauv cov dej phwj nitrogen nyob rau hauv lub sab sauv yog lub ntsiab qhia ntawm lub extraction tus nqi ntawm rectification thiab extraction.Kev ntsuas qhov tseeb qhia tau hais tias cov pa oxygen hauv cov dej phwj tuaj yeem tsawg dua 0.1%, thiab txawm tias ncav cuag 150-200x10-4%.

Sab saum toj ntawm cov txheej txheem ntim khoom thiab cov kab argon crude muaj kev sib cais siab, uas yog qhov tshwm sim ntawm lawv cov kev ua haujlwm siab heev.Qhov qis dua ntawm kev ua haujlwm siab, qhov zoo dua qhov kev sib cais ntawm cov pa oxygen, nitrogen thiab argon, thiab kev sib cais ntawm oxygen thiab argon..Feem ntau, qhov rho tawm ntawm cov pa oxygen tuaj yeem nce los ntawm 1% mus rau 3%;Qhov kev rho tawm ntawm argon tuaj yeem nce los ntawm 5% mus rau 10%.

Tus nqi rho tawm ntawm cov pej thuam rectifying kuj nyob ntawm qhov loj ntawm cov huab cua nthuav dav nkag mus rau sab saud, uas muaj kev cuam tshuam zoo rau kev rho tawm tus nqi ntawm argon.Yog li ntawd, lub isentropic efficiency ntawm lub turboexpander thiab lub booster piv ntawm lub booster yog tsis tu ncua nce., yog tus yuam sij kom nce tus nqi rho tawm ntawm kab distillation.

2. Lub void ntawm cov txheej txheem packing yog loj, lub peev xwm ntau lawm yog loj, thiab txoj kab uas hla ntawm tus pej thuam raug txo kom yooj yim rau kev thauj mus los.

Lub porosity ntawm cov txheej txheem ntim tuaj yeem ncav cuag ntau dua 95%.Nyob rau hauv lub sieve phaj kem, thaj tsam ntawm lub orifice phaj nyiaj li ntawm 80% ntawm tus ntoo khaub lig seem ntawm kem, thiab qhib tus nqi yog hais txog 8 mus rau 12%, uas yog deb tsawg tshaj li cov huab cua poob nqi ntawm cov packing. txheej.Rau tib lub thauj khoom, kab kab kab sib piv ntawm cov kab ntim khoom Lub sieve tais ntauwd yog me me;Feem ntau, nws qhov chaw hla ntu tsuas yog ~ 70% ntawm lub sieve tais ntauwd, uas muaj txiaj ntsig zoo rau kev thauj mus los rau cov nroj tsuag loj huab cua sib cais.

3. Cov txheej txheem ntim khoom muaj peev xwm tuav tau tsawg dua, kev ua haujlwm loj dua ntawm cov kua-rau-gas piv thiab elasticity, thiab hloov ceev ceev ua haujlwm.

Kev khiav hauj lwm load ntawm sieve tray yees yog txwv los ntawm sieve to thiab kua dej nyab ceev, thaum packed yees tsuas yog txwv los ntawm cov kua dej nyab ceev, yog li lawv cov kev khiav hauj lwm loads yuav txawv nyob rau hauv ib tug ntau yam, thiab tsim load ntau yam ntawm packed yees tuaj yeem ncav cuag 40. % ~ 120%, cov pa tawm ntawm cov pej thuam sab saud ntawm cov txheej txheem ntim ntawm 12000m3 / h huab cua sib cais cog ntawm Shanghai Hlau thiab Hlau No. 5 Cog tuaj yeem hloov kho nyob rau hauv thaj tsam ntawm 9000 ~ 14000mm3 / h, thiab kev khiav hauj lwm load Qhov ntau tsuas yog 75% ~ 117%.

Vim tias cov kua ntim me me ntawm cov ntim ntauwd, feem ntau tsuas yog 1% mus rau 6% ntawm cov pej thuam ntim, thaum cov kua tuav ntawm lub sieve tais ntauwd yog 8% rau N% ntawm ntauwd ntim.Lub sijhawm nyob hauv lub sijhawm luv luv thiab kev ua haujlwm siab poob qis me me, uas yog qhov tsim nyog rau kev ua haujlwm ntawm kev ua haujlwm tsis sib xws, tab sis nws yuav tsum tau txheeb xyuas qhov tseeb ntawm kev ua haujlwm tsis sib xws hauv kev ua haujlwm yav tom ntej.

4. Lub sijhawm pib ntawm lub cuab yeej yog luv heev

Cov txheej txheem pib ntawm huab cua sib cais cog tsis muaj cov khoom lag luam tso tawm, yog li shortening lub sij hawm pib-up yog ib txoj hauv kev rau huab cua sib cais cog kom txuag hluav taws xob thiab txo qhov poob.Tom qab siv cov txheej txheem ntim khoom uas twb muaj lawm, cov kua uas nws tuav tau thaum lub sij hawm hloov kho ib txwm raug txo qis, uas ua rau lub sijhawm pib ntawm huab cua sib cais.
