Sodium Hypochlorite Generator

Sodium hypochlorite generator yog dab tsi?

Sodium hypochlorite generator, txwv tsis pub hu ua clortec sodium hypochlorite generator los yog sodium hypochlorite electrolysis generator, yog ib qho kev txawj ntse thiab kev nyab xeeb cordial iav rau xa cov sodium hypochlorite kev npaj.

Lub tshuab hluav taws xob ua haujlwm los ntawm kev siv electrolysis los hloov cov ntsev thiab dej rau hauv sodium hypochlorite kev npaj. Txoj kev npaj yog siv los ua tshuaj tua kab mob hauv kev lag luam sib txawv, piv txwv li, kev kho dej, kev tuav zaub mov, thiab kev kho mob.

Sib piv nrog cov pa roj chlorine los yog kua dej blanch, sodium hypochlorite tsim los ntawm cov khoom siv no muaj kev nyab xeeb dua rau kev cuam tshuam thiab kev thauj mus los, vim nws tsis muaj txiaj ntsig zoo. Tsis tas li ntawd, nws txo qis qhov tshwm sim ntawm kev raug xwm txheej thiab kev ua qias tuaj ntawm ib puag ncig los ntawm kev tshem tawm qhov xav tau khaws cia thiab tswj cov tshuaj lom neeg.

Tsis tas li ntawd, lub tshuab hluav taws xob muab qhov kev xav tau thiab kev cia siab tau zoo ntawm sodium hypochlorite kev npaj, lav qhov siab ntawm kev ua kom huv huv. Nws tsis yooj yim rau kev ua haujlwm thiab khaws cia, nrog cov khoom siv tsis tseem ceeb rau cov ntaub ntawv sib txuas thiab kev siv hluav taws xob.

1. Lub hauv paus ntsiab lus ua haujlwm ntawm electrolysis ntawm seawater los tsim sodium hypochlorite

Cov tshuaj tiv thaiv anode: 2Cl-→Cl2+2e (1)

Cov tshuaj tiv thaiv cathodic: 2H2O+2e→2OH-+H2 (2)

Tshuaj tiv thaiv ntawm ncej:

Cl2+2OH-=ClO- + Cl- + H2O (3)

ClO- + H2O=HClO + OH- (4)

HClO=H+ + ClO- (5)

Zuag qhia tag nrho cov lus teb:

NaCl + H2O- → NaCl + H2 (6)

Cov tshuaj tiv thaiv kev sib npaug (3) ~ (5) feem ntau yog nyob ntawm tus nqi pH thiab qhov kub thiab txias. Tus nqi pH ntawm cov dej hiav txwv yog 8. 20%) daim ntawv ntawm hypochlorite ion (ClO-) sib tov.

Ntxiv nrog rau cov tshuaj tiv thaiv saum toj no, vim muaj cov calcium thiab magnesium ions hauv dej hiav txwv, tom qab lub sijhawm ntev ntawm electrolysis, cov ions yuav tsim calcium thiab magnesium deposits ntawm cathode, ua rau lub zog noj ntawm electrolysis. Yog li ntawd, cov Precipitate yuav tsum tau tshem tawm tsis tu ncua los ntawm pickling.

2. Cov khoom tseem ceeb ntawm electrolyzer

2.1. Electrolyzer npog. Lub npog phaj yog ua los ntawm pob tshab plexiglass (acrylic), thiab tus neeg teb xov tooj tuaj yeem ncaj qha saib cov tshuaj tiv thaiv hauv lub tank los ntawm lub npog phaj thaum ua haujlwm, uas yog qhov zoo rau kev txiav txim siab intuitively thiab tuav lub sij hawm ntawm electrolytic tank tu thiab pickling.

2.2. Electrolyzer plhaub. Lub plhaub yog ua los ntawm cov khoom siv PVC uas tiv taus corrosion los ntawm sodium hypochlorite, thiab cov dej nkag thiab qhov hluav taws xob txuas nrog flanges. Cov qauv muaj kev ruaj ntseg thiab ruaj khov dua, thiab tshem tawm cov teeb meem ntawm cov kua xau.

2.3. Anode. Lub anode txais yuav DSA anode coated nrog ib tug noble hlau oxide txheej ntawm titanium. Lub anode muaj kev ua haujlwm zoo electrochemical ntawm 0 ~ 45 degree, thiab muaj cov yam ntxwv siv lub neej ntev. Lub anode yog nyob rau hauv cov duab ntawm ib tug mesh phaj, uas ua rau kom seawater turbulence thiab txhim kho electrolysis efficiency. Lub phaj mesh anode muaj thaj chaw ua haujlwm loj dua li lub phaj anode, uas txhim kho cov tshuaj chlorine. PVDF spacer rau tes yog siv rau anode thiab cathode kom muaj 2.5 hli suab.

2.4. Cathode.Titaniumcathodes feem ntau yog siv, tab sis qee cov neeg siv khoom siv Hastelloy alloys. Hastelloy alloys muaj zog corrosion kuj nyob rau hauv seawater thiab sodium hypochlorite media. Lub peev xwm hydrogen evolution yog 0.45V qis dua li ntawm titanium cathodes. Qhov saum npoo yog polished thiab calcium txo. Lub deposition ntawm magnesium deposits yuav tsis tsim hydrogen embrittlement corrosion.

2.5. Kev sib khi. Kev sib khi ntawm cov khoom siv hauv qhov zawj siv fluorine roj hmab O-rings, thiab kev sib khi ntawm lub plhaub thiab lub hau siv silicone roj hmab O-rings.

2.6. Hlau qhov chaw. Cov ntaub ntawv ntawm cov fasteners nyob rau hauv qhov zawj thiab cov khoom siv yog tag nrho cov titanium, thiab cov fasteners sab nraud yog 316 stainless hlau. Tag nrho cov fasteners yog nruj nreem nrog ib tug torque ciaj ntswj raws li lub torque teev los xyuas kom meej qhov kev cia siab ntawm lub foob.

2.7. Kev coj ua. Lub conductive connector ntawm cathode los yog anode ntawm lub electrolytic cell yog titanium clad tooj liab pas nrig. Cov pas nrig cladding tau muab faib ua titanium hauv cell thiab tooj liab sab nraum lub cell, thiab cov phaj tooj liab yog siv rau kev sib txuas hluav taws xob ntawm cov hlwb.

3. Ceev faj
Cov ntaub ntawv ntsig txog qhia tau hais tias qhov nce viscosity ntawm cov dej hiav txwv qis yuav ua rau cov khoom siv chlorine tsis txaus thiab ua rau cov phaj fouling. Yog li cov kev khiav hauj lwm cov kev cai ntawm lub hwj chim cog: thaum lub inlet seawater kub poob qis dua 18 degree, qhov kev khiav hauj lwm tam sim no ntawm sodium hypochlorite generator yog txo; Thaum cov dej hiav txwv kub poob qis dua 10 degree, lub tshuab hluav taws xob sodium hypochlorite raug kaw. Thiab cov txheej txheem electrolysis rau kev tsim cov tshuaj chlorine tsis tas yuav tsum muaj kev txwv sab sauv ntawm salinity ntawm cov dej nyoos. Feem ntau, qhov siab dua qhov salinity, qhov siab dua cov electrolysis efficiency.
