Sodium Hypochlorite Generator

Cov khoom siv ua tiav sodium hypochlorite tau siv dav hauv ntau qhov chaw, thiab nws cov ntawv thov tseem ceeb suav nrog:
Cov dej haus tshuaj tua kab mob thaj chaw:
Cov dej hauv cheeb tsam decentralized: me me - nplai sodium hypochlorite generators tuaj yeem ntsia tau ncaj qha ntawm ib sab ntawm cov dej hauv dej los yog cov reservoirs los daws cov teeb meem dej haus tshuaj tua kab mob hauv thaj chaw deb
Cov dej hauv lub raj mis / cov chaw tsim khoom dej: Cov khoom noj tsim tawm -qib sodium hypochlorite tuaj yeem ua tiav cov tshuaj tua kab mob sib sib zog nqus ntawm cov dej ntau lawm, ntsuas qhov ua kom tsis muaj menyuam thiab cov dej zoo saj
Cov dej hauv nroog: Los ntawm electrolyzing dej ntsev los tsim cov tshuaj sodium hypochlorite, nws tuaj yeem tua cov kab mob tsis zoo xws li kab mob thiab kab mob hauv dej.
Kev kho dej khib nyiab muaj:
Pharmaceutical, tshuaj, thiab dyeing industries kev kho dej khib nyiab: Los ntawm oxidation kom decompose cov teeb meem hauv dej khib nyiab, txo COD thiab BOD, thaum tua cov kab mob kab mob.
Kev lag luam ntawv: Raws li lwm txoj hauv kev tshuaj pleev ib ce, ua tiav daim ntawv pulp yam tsis muaj pov tseg bleaching
Kev lag luam hluav taws xob hluav taws xob: Siv nyob rau hauv cov dej txias txias los tiv thaiv kab mob loj hlob thiab tiv thaiv cov yeeb nkab corrosion thiab scaling
Kev kho dej khib nyiab:
Cov chaw kho dej khib nyiab hauv nroog: Siv rau kev tua kab mob tua kab mob xws li Escherichia coli
Kev kho cov dej khib nyiab kho mob: Kev ua kom tsis muaj menyuam sai thiab ua tau zoo, ua tau raws li cov kev cai nruj rau cov dej khib nyiab kho mob
Cov pas dej da dej, qhov dej kub, dej hiav txwv, thiab lwm yam: tuaj yeem tswj cov tshuaj tua kab mob kom ntseeg tau tias dej nyab xeeb
Lwm yam kev siv:
Kev lag luam ua zaub mov: Rau cov khoom siv, ntim khoom, thiab cov kab ntau lawm tshuaj tua kab mob
Electroplating wastewater kho: Oxidation decomposition ntawm cyanide-muaj cov dej khib nyiab
Textile printing thiab dyeing kev lag luam: Tshem tawm cov xim dej khib nyiab thiab tsw, siv los ua cov tshuaj dawb

Vim nws txoj hauv kev yooj yim thiab cov txheej txheem tsim khoom yooj yim, tsuas yog 10 grams dej ntsev ua ke nrog 600 milliampere tam sim no tuaj yeem tawm 2000 ppm qib ntawm 84 tshuaj tua kab mob. Cov khoom lag luam nta lub nplhaib- zoo li ruthenium iridium electrode thiab lub raj mis tsim. Nws yog nrov thoob ntiaj teb. Cov khoom siv hluav taws xob tuaj yeem ua ntau yam xws li phaj-zoo li, mesh-zoo li, thiab raj-zoo li.

Cov hauv qab no yog cov txheej txheem ntws ntawm sodium hypochlorite generator:
1. Mos - dej npaj cov ntaub ntawv raw
Cov kais dej ua ntej dhau los ntawm cov dej softener rau softening kho kom tshem tawm calcium thiab magnesium ions nyob rau hauv dej thiab txo cov dej hardness. Qhov no yog los tiv thaiv cov electrodes ntawm scaling thaum lub sij hawm tom ntej electrolysis txheej txheem. Ib feem ntawm cov dej softened yog siv los ua qhov standby, thiab lwm qhov nkag mus rau hauv cov ntsev - dissolving tank.
2. Ntsev - dissolving rau daim brine
Nyob rau hauv ntsev - lub tank dissolving, cov dej softened yog tov nrog refined ntsev (ntxiv los ntawm ib tug tsis siv neeg ntsev - noj tshuab) los tsim ib tug saturated concentrated brine. Nyob rau tib lub sijhawm, qee cov dej softened nkag mus rau hauv lub tank dej softened rau kev npaj dilute brine nrog ib tug concentration ntawm txog 3%.
3. Kev npaj ntawm dilute brine
Cov concentrated brine thiab dej softened yog raug ntsuas los ntawm metering twj thiab ces sib tov nyob rau hauv ib qho kev faib ua feem los npaj ib tug dilute brine nrog ib tug concentration ntawm 3% - 5%, uas ua tau raws li qhov yuav tsum tau rau electrolysis.
4. Cov txheej txheem electrolysis
Cov npaj dilute brine nkag mus rau hauv electrolytic cell. Nyob rau hauv qhov kev txiav txim ntawm ncaj qha tam sim no nyob rau hauv lub electrolytic cell, cov nram qab no tshwm sim:
Chloride ions nyob rau hauv brine yog oxidized rau hauv chlorine gas ntawm lub anode.
Cov dej molecules raug txo rau hauv hydrogen gas thiab hydroxide ions ntawm cathode.
Cov roj chlorine uas tsim los ua rau dej los tsim cov kua qaub hypochlorous, thiab tom qab ntawd hypochlorous acid reacts nrog hydroxide ions los ua sodium hypochlorite. Cov kev sib npaug sib npaug yog raws li nram no:
Cov tshuaj sodium hypochlorite generated muaj qhov concentration ntawm 0.6% - 0.8%.
5. Hydrogen tshem tawm
Thaum cov txheej txheem electrolysis, hydrogen gas yog tsim los ntawm - khoom. Txij li thaum hydrogen yog flammable thiab tawg, ib tug hydrogen - extinguishing kiv cua ua hauj lwm los nqus cov generated hydrogen gas thiab tso tawm rau hauv cov huab cua tom qab txo nws cov concentration mus rau ib tug zoo theem (feem ntau, qhov ratio ntawm huab cua rau hydrogen yog saum toj no 100: 1).
6. Cia ntawm sodium hypochlorite
Cov tshuaj sodium hypochlorite generated nkag mus rau hauv cov zaub mov - qib PE cia tank rau cia.
7. Dosing
Cov tshuaj sodium hypochlorite nyob rau hauv lub tank yog ntxiv rau kev kho dej los ntawm ib pab pawg neeg siv tshuaj tua kab mob raws li qhov xav tau tiag tiag rau kev tua kab mob.
8. Electrode tu
Lub tshuab hluav taws xob sodium hypochlorite yuav tsum tau ntxuav tsis tu ncua. Feem ntau, nws raug ntxuav ib zaug tom qab khiav rau 250 teev, thiab lub voj voog ntxuav tuaj yeem txuas ntxiv lossis luv luv raws li cov dej zoo. Cov kauj ruam tu yog raws li nram no:
Qhib cov dej phwj tuaj rau tom qab ntawm lub tshuab hluav taws xob kom tso tawm cov kua dej khib nyiab thiab cov khoom siv hluav taws xob hauv cov hluav taws xob hluav taws xob.
Qhib lub inlet valve ntawm lub alkali chamber rau dej - dhau mus txog thaum cov dej ntshiab ntws tawm ntawm lub qhov hluav taws xob nram qab, ces kaw lub inlet valve ntawm lub alkali chamber.
Cia cov dej ntshiab tso rau hauv lub cell electrolytic rau 1 - 2 teev thiab tom qab ntawd ntws dej, thiab nqa tawm rov qab - yaug ib zaug. Qhov concentration ntawm cov tshuaj hydrochloric acid siv los ntxuav yog feem ntau txog 10%.
