Carbon Molecular Sieve Cms 280 Raws li Adsorbent hauv PSA Nitrogen Generator

Kev npaj ntawmcarbon molecular sieverau nitrogen generator: Cov pa roj carbon molecular sieve siv nyob rau hauv lub tshuab hluav taws xob nitrogen feem ntau yog tsim los ntawm cov ntsiab lus carbon, thiab nws cov tsos yog ib tug dub columnar khoom. Nws tuaj yeem tsim cov nitrogen los ntawm cov khoom siv siab viav vias adsorption (PSA).

PSA nitrogen ntau lawm txoj kev:
Hauv PSA (Pressure Swing Adsorption) nitrogen ntau lawm txoj kev, cov pa roj carbon molecular sieve tuaj yeem nqus cov pa oxygen thiab nitrogen hauv huab cua tib lub sijhawm, tab sis vim tias qhov diffusion ntawm oxygen molecules yog ntau pua lub sij hawm sai dua li nitrogen, los ntawm kev tswj lub sij hawm adsorption, feem ntau ntawm cov pa oxygen tuaj yeem adsorbed nyob rau hauv lub sij hawm luv dua, thaum nitrogen tsis muaj adsorption ntawm nitrogen.

Adsorption thiab desorption txheej txheem:
Nyob rau hauv cov txheej txheem PSA nitrogen ntau lawm, adsorption thiab desorption yog ua tiav los ntawm qhov sib txawv siab. Thaum lub siab nce, cov pa roj carbon molecular sieve adsorbs oxygen; Thaum lub siab poob qis, lub molecular sieve tso tawm cov pa adsorbed, yog li ua tiav desorption.

Txheej txheem khiav:
Cov txheej txheem tseem ceeb ntawm PSA nitrogen ntau lawm suav nrog huab cua compression, purification, nkag mus rau ntauwd adsorption rau oxygen thiab nitrogen sib cais, thiab rov tsim dua tshiab ntawm molecular sieve los ntawm cov kauj ruam xws li kev sib npaug thiab rov qab.

Qhov system muaj pes tsawg leeg:
PSA nitrogen ntau lawm system muaj cua compressor, cua purification system, cua cia tank, hloov valve, adsorber thiab oxygen buffer tank. Lub kaw lus tau txais kev tswj hwm los ntawm PLC thiab tsis siv neeg hloov lub valve kom ntseeg tau tias kev tsim khoom tsis tu ncua ntawm siab - zoo nitrogen.

Selective adsorption ntawm molecular sieve:
Cov cuab yeej molecular sieve tuaj yeem ua tiav kev ua tau zoo, txuas ntxiv thiab ruaj khov nitrogen npaj, thiab tuaj yeem cais siab -purity nitrogen los ntawm huab cua.

Cov yam ntxwv ntawm carbon molecular sieve:
Cov pa roj carbon molecular sieve yog ib qho siv adsorbent hauv PSA nitrogen generator. Nws txoj kev sib cais ntawm cov pa oxygen thiab nitrogen yog nyob ntawm qhov sib txawv ntawm qhov sib txawv ntawm ob lub gases nyob rau saum npoo ntawm molecular sieve.

Specification

Dab tsi yog qhov kev txiav txim siab ntawm nitrogen ntau lawm cov txiaj ntsig ntawm carbon molecular sieves?

A/ Microporous Structure thiab Surface Properties
1. Pore loj faib: Lub pore loj faib ntawm cov pa roj carbon molecular sieves yuav tsum ua kom haum cov pa roj molecules xws li nitrogen thiab oxygen. Nws qhov nruab nrab qhov pore loj yog feem ntau ntawm 0.3 thiab 1.0 nanometers. Nyob rau hauv cov xwm txheej zoo, nws tso cai rau oxygen molecules nkag mus rau micro- pores thaum thaiv cov molecules nitrogen. Los ntawm cov nyhuv sieving no, nitrogen thiab oxygen tau sib cais, yog li tau txais siab -purity nitrogen.
2. Cov cheeb tsam tshwj xeeb: Qhov loj dua ntawm thaj chaw tshwj xeeb, qhov muaj zog adsorption muaj peev xwm ntawm cov pa roj carbon molecular sieve, uas tuaj yeem adsorb ntau cov pa oxygen molecules thiab yog li txhim kho cov nyhuv nitrogen ntau lawm. Qhov chaw siab tshwj xeeb muab cov chaw ua haujlwm ntau dua rau cov pa roj adsorption, ua kom cov pa roj carbon molecular sieves ua rau huab cua ntau dua thiab tsim cov ammonia ntau dua hauv ib chav tsev ntawm lub sijhawm.

B / Filling ntim thiab uniformity
1. Filling ntim: Hauv cov khoom siv ammonia, cov ntim ntim ntawm cov pa roj carbon molecular sieves ncaj qha cuam tshuam rau cov nyhuv nitrogen ntau lawm. Tsis txaus ntim ntim ua rau nws tsis tuaj yeem ua tiav cov huab cua nyoos, thiab nws nyuaj kom tau txais siab -purity thiab txaus tso tawm nitrogen. Txawm li cas los xij, kev thauj khoom ntau dhau tuaj yeem ua rau muaj teeb meem xws li cov khoom siv hluav taws xob ntau ntxiv thiab kev tiv thaiv lub txaj ntau dhau.
2. Filling uniformity: Lub filling uniformity ntawm carbon molecular sieves nyob rau hauv lub adsorption ntauwd kuj tseem ceeb heev. Yog tias cov filling tsis sib xws, nws yuav ua rau tsis sib xws ntawm cov roj hauv cov pej thuam, uas ua rau ntau dhau los yog tsis txaus adsorption hauv qee qhov chaw, uas yuav cuam tshuam rau tag nrho cov adsorption thiab kev sib cais thiab txo cov purity thiab tso tawm ntawm nitrogen.
