Flotation Reagents Daim Ntawv Thov & Tshuaj Dosing Technology Guide
I. Txheej txheem cej luam ntawm Flotation Reagents
Kev kho dej khib nyiab nyob ntawm kev siv cov flotation reagents. Adsorption, flocculation thiab kev sib cais tom qab ntawm cov khib nyiab thiab cov colloidal hauv cov dej khib nyiab tau txhawb nqa, yog li ua kom cov khoom sib cais-kua. Cov pawg tseem ceeb ntawm flotation reagents yog raws li hauv qab no:
1. 
Inorganic Coagulants: Piv txwv xws li txhuas sulphate, ferric chloride thiab polyaluminum chloride (PAC).
Cov neeg ua haujlwm no feem ntau muab cov nqi zoo rau kev ua kom tsis zoo rau cov khoom siv colloidal hauv cov dej khib nyiab, thiab tsim cov flocs loj.
2. Organic Polymer Flocculants: Natural modified polymer flocculants (piv txwv li, chitosan) nrog rau cov hluavtaws polymer flocculants (piv txwv li, polyacrylamide, PAM) suav nrog. Lawv ntev saw molecular qauv yog zoo raws li nws txuas hniav thiab ntxiab tshem tawm hais los tsim flocs ruaj khov.
3. Composite Flocculants: Lawv qhia qhov zoo ntawm ob qho tib si inorganic coagulants thiab organic polymer flocculants tab sis muaj zog flocculation kev ua tau zoo thiab dav siv tau.
4. Coagulant Aids: Piv txwv li, activated silica thiab sodium polyacrylate uas txhim khu cov nyhuv coagulation, txhim kho flocs qauv, thiab txhim kho flotation efficiency.
II. Kev Siv Tshuaj
Txoj kev flotation reagents yog dosed muaj kev cuam tshuam ncaj qha rau yuav ua li cas kho tau zoo, thiab tseem cuam tshuam rau tus nqi kho mob. Txoj kev siv tshuaj ntau ntau suav nrog:
1. Dry Dosing: Dosing equipment ncaj qha disperses qhuav hmoov reagents rau hauv dej khib nyiab. Txoj kev no, txawm tias zoo rau kev kho me me lossis cov xwm txheej ceev, yuav tsum tsis txhob hnov qab, vim nws yooj yim rau plua plav dispersal.
2. Kev ntim dej ntub dej: Muab cov tshuaj reagents kom raug rau hauv qhov kev kho dej khib nyiab yog ua tiav nrog kev siv lub tshuab ntsuas ntsuas qhov twg cov reagents yaj hauv dej los ua cov tshuaj ntawm qhov tshwj xeeb. Nrog rau txoj kev no uniform dosing, raws li zoo raws li kev tswj xyuas, yog tiav.
III. Cov khoom siv sib xyaw
Cov cuab yeej sib xyaw ua kom ntseeg tau tias cov tshuaj reagents zoo sib xyaw nrog cov dej khib nyiab. Cov hom kev sib xyaw ua ke muaj xws li:
1. Dosing System:
Nws pib Polymer Dosing System: (Peb nplooj ntawv khoom) Kuj hu ua high efficiency pib polymer npaj dosing unit, uas tuaj yeem npaj thiab pov cov tshuaj polymer tsis tu ncua. Nws tuaj yeem ua kom tiav cov tshuaj sib xyaw ua ke thiab sib xyaw ntawm cov polymer txuas ntxiv thiab ua tau zoo kom tau txais homogeneous thiab qhib kev daws teeb meem.
Los ntawm txhais tes Tshuaj Dosing System: (Peb cov khoom nplooj ntawv)Feem ntau muaj cov tshuaj tov tank, agitator, dosing twj, thiab kev txhawb nqa ncej (uas tuaj yeem teeb tsa raws li tus neeg siv cov kev xav tau tshwj xeeb). Lub kaw lus npaj cov tshuaj uas xav tau kev daws teeb meem nyob rau hauv lub tank sib tov, qhov twg nws yog kom huv si tov los ntawm agitator thiab ces pauv mus rau lub tov tov tank.
2. Pipeline Mixers: Cov khoom sib xyaw tau muab tso rau hauv lub raj xa dej kom sib xyaw cov dej khib nyiab nrog cov tshuaj reagents hauv cov txheej txheem kev kho dej khib nyiab kom muaj txiaj ntsig zoo thiab nrawm ntawm cov tshuaj reagents nrog cov dej khib nyiab. Kev sib xyaw ua ke yog muab los ntawm kev siv lub zog kinetic ntawm cov dej khib nyiab uas ntws tawm, uas ua rau muaj kev sib cais thiab nrawm nrawm los yog cov tshuaj tiv thaiv ntawm cov reagent hauv cov dej khib nyiab.
IV. Cov yam tseem ceeb suav nrog hauv kev suav tshuaj
Kev suav cov koob tshuaj yuav tsum xav txog ntau yam, suav nrog:
1. Cov dej khib nyiab zoo: Kev siv cov flotation reagents yog cuam tshuam los ntawm ntau yam xws li cov ntsiab lus ntawm cov khib nyiab tshem tawm, cov ntsiab lus colloid, pH thiab dej kub. Raws li ib qho piv txwv, kom tswj tau qhov kev kho mob zoo, kev siv tshuaj reagent ntau dua yog xav tau rau ntau dua ntawm cov khoom raug tshem tawm.
2. Hom thiab Kev Ua Haujlwm ntawm Reagents: Cov reagents sib txawv muaj qhov sib txawv ntau npaum li cas thiab kev ua tau zoo, raws li cov khoom, lub hom phiaj, thiab cov xwm txheej ntawm cov dej khib nyiab raug kho.
3. Kev Sib xyaw thiab Kev Ua Txhaum Cai: Kev sib xyaw lub zog thiab lub sijhawm tshuaj tiv thaiv yog qhov tseem ceeb cuam tshuam rau cov nyhuv flocculation, ob qho tib si paub tias yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov tshuaj reagents.
4. Cov txheej txheem thiab cov khoom siv tsim: Tsis tas li ntawd, hom kev ua cua txias thiab kev tsim ntawm lub flotation tank kuj cuam tshuam rau cov kev xav tau ntau npaum li cas.
V. Kev suav cov qauv thiab cov txheej txheem
Cov txheej txheem feem ntau rau kev suav cov koob tshuaj muaj xws li:
1. Txoj Kev Loj Loj: Nws suav nrog kev tshuaj xyuas cov qauv dej pov tseg hauv cov ntsiab lus ntawm cov khoom raug tshem tawm lossis cov ntsiab lus colloidal rau kev txiav txim siab tom qab ntawm qhov xav tau ntawm cov reagents los ntawm cov qauv empirical.
2. Volume Ratio Method: Nyob ntawm qhov ntim ntawm cov dej khib nyiab thiab cov pa phem concentration ntawm cov dej khib nyiab, txoj kev no suav cov kev siv tshuaj ntau npaum li cas.
3. Empirical Formula Method: Cov ntaub ntawv thiab kev ua haujlwm dav dav kuj tseem tso cai rau kev muab cov khoom siv coj los siv.
VI. Dosing Adjustment Strategies
Kev siv ntau npaum li cas tuaj yeem hloov kho nyob rau hauv kev xyaum raws li kev kho mob, tus nqi ua haujlwm thiab kev hloov hauv dej zoo. Cov tswv yim hloov kho muaj xws li:
1. Kev Ntsuas Me Me: Txhawm rau txiav txim siab qhov kev noj tshuaj kom zoo, ua cov kev tshuaj ntsuam xyuas raws li ntau yam kev txhaj tshuaj.
2. Kev Saib Xyuas Online: Thiab siv cov cuab yeej saib xyuas lub sijhawm los ntsuas cov dej zoo thiab tom qab ntawd kho cov tshuaj.
3. Kev Ntsuam Xyuas Lub Sij Hawm: Kev soj ntsuam ntau zaus thiab ua tib zoo saib xyuas kev ua tau zoo ntawm kev kho mob thiab kev hloov kho cov tshuaj noj uas tsim nyog los teb rau kev hloov pauv dej zoo thiab hloov cov kev xav tau ua haujlwm.
VII. Kev nyab xeeb thiab ib puag ncig ntawm kev txiav txim siab
Thaum siv flotation reagents, nws yog ib qho tseem ceeb kom ua raws li kev nyab xeeb thiab ib puag ncig cov cai los tiv thaiv cov neeg ua haujlwm thiab ib puag ncig:
1. Kev Tiv Thaiv Kev Nyab Xeeb: Kev sib cuag ncaj qha nrog cov tshuaj reagents yuav tsum zam los ntawm cov neeg ua haujlwm uas yuav tsum tau muab cov iav tiv thaiv.
2. Reagent Cia: Vim qee cov reagents degrade thaum raug ya raws los yog kub, lawv yuav tsum tau muab khaws cia raws li cov chaw tsim tshuaj paus cov lus qhia.
3. Kev pov tseg cov dej khib nyiab: Tsis txhob tso cov dej khib nyiab pov tseg thiab xyuas kom nws ua tau raws li cov qauv tso tawm kom tsis txhob muaj kuab paug.
4. Kev tuav pov tseg: pov tseg cov ntim khoom siv reagent, thiab cov reagents seem, kom ua raws li cov kev cai ib puag ncig.
