Dissolved air flotation (DAF) cov cuab yeej sawv cev rau cov cuab yeej siv dej huv siab tshaj plaws uas tshem tawm cov khib nyiab thiab cov kab mob ntom ntom. Paub txog kev siv hluav taws xob tsawg, kev ua haujlwm zoo tshaj plaws, thiab kev saib xyuas yooj yim - ntxiv rau kev teeb tsa uas tsis tas yuav tsum muaj lub hauv paus - cov chav no sawv tawm raws li cov kev daws teeb meem zoo hauv kev kho dej khib nyiab niaj hnub no. Txhawm rau xaiv DAF cov cuab yeej tsim nyog tshaj plaws uas phim koj cov kev xav tau tiag tiag, koj tuaj yeem ua raws cov kauj ruam hauv qab no, ua ke nrog cov cuab yeej tshwj xeeb, cov khoom thiab daim ntawv thov scenarios.
1. Sib piv cov cuab yeej ua haujlwm nrog koj cov kev xav tau kho
Cov khoom siv DAF muab cov khoom zoo tshaj plaws thiab kev ua tau zoo, thiab koj yuav tsum xaiv nws raws li qhov koj xav tau kom muaj txiaj ntsig zoo thiab kev cia siab rau kev ua haujlwm:
- Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob: Cov khoom siv DAF no muaj cov txiaj ntsig zoo heev, nrog rau SS tshem tawm tus nqi Ntau dua lossis sib npaug li 95% thiab cov nqi tshem tawm tsis zoo COD Ntau dua lossis sib npaug li 70%, uas tuaj yeem ua kom cov dej huv huv. Yog tias koj qhov project xav tau cov dej ntws zoo (xws li nruj SS thiab insoluble COD ntsuas), cov khoom siv no tuaj yeem ua tau raws li qhov xav tau. Tsis tas li ntawd, nws muaj peev xwm tsim tau siab -scum zoo ib yam (txog 4%), uas yog yooj yim rau kev kho scum tom ntej.
- Kev Tswj Xyuas Kev Siv Hluav Taws Xob thiab Tshuaj: Piv nrog rau lwm yam khoom siv DAF, cov koob no muaj lub zog pom tseeb -txuag thiab tshuaj lom neeg-txuag qhov zoo-50% qis zog noj thiab 50% qis dua tshuaj lom neeg noj. Yog tias koj them sai sai rau cov nqi ua haujlwm ntev - lub sijhawm ua haujlwm, cov khoom siv no yog qhov kev xaiv zoo. Nyob rau tib lub sijhawm, koj tuaj yeem xa mus rau lub zog tsis muaj zog ntawm cov khoom tseem ceeb (dej rov qab twj tso kua mis, scraping unit motor, air compressor motor) ntawm cov qauv sib txawv kom haum rau koj cov khoom siv fais fab.
- Kev tu thiab kev ua haujlwm yooj yim: Cov cuab yeej muaj cov qauv compact, ruaj khov, zoo li zoo nkauj thiab tsis tshua muaj nqi txij nkawm, uas tsim nyog rau cov xwm txheej uas ua haujlwm yooj yim thiab ua haujlwm qis tom qab. Nws cov huab cua dissolution tank ua hauj lwm nyob rau hauv ib tug tshwj xeeb siab (feem ntau 0.2-0.4 MPa), nrog ib tug nruab nrab sib tov lub sij hawm ntawm txog 13 feeb (kho raws li cov roj txhaj tshuaj mus kom ze), thiab tag nrho cov lag luam yog ruaj khov thiab yooj yim rau tswv.
2. Muab cov xwm txheej thov kom paub meej tias tsim nyog
Cov cuab yeej DAF no muaj ntau yam kev siv, thiab koj yuav tsum paub meej tias nws puas phim koj qhov kev kho dej khib nyiab tshwj xeeb:
Nws yog qhov tsim nyog rau cov dej dawb reclamation hauv kev lag luam papermaking, thiab kev kho dej khib nyiab hauv cov nroj tsuag tshuaj, kev lag luam tshuaj, dej phwj hauv nroog, textile dyeing, electroplating thiab roj- muaj cov dej khib nyiab. Yog tias koj qhov project belongs rau ib qho ntawm cov xwm txheej saum toj no, cov khoom siv DAF no tuaj yeem siv ncaj qha. Piv txwv li, hauv cov roj- muaj kev kho dej khib nyiab, nws cov khoom siv tau zoo- muaj peev xwm sib cais ua kua tuaj yeem tshem tawm cov roj thiab cov khib nyiab pov tseg; nyob rau hauv papermaking dej dawb reclamation, nws tuaj yeem pab paub txog kev siv dej rov ua dua tshiab, nqa cov txiaj ntsig kev lag luam.
3. Xav txog ntawm -Qhov chaw teeb tsa thiab kev ua haujlwm
- Cov Txheej Txheem Kev Txhim Kho: Ib qho ntawm qhov zoo ntawm cov cuab yeej no yog tias nws tsis tas yuav muaj lub hauv paus rau kev teeb tsa, uas tuaj yeem txuag tau ntawm - lub sijhawm tsim kho thiab cov nqi. Koj tsuas yog yuav tsum xyuas kom meej tias qhov chaw nyob ntawm - qhov chaw ua tau raws li qhov yuav tsum tau muaj ntawm cov qauv uas tau xaiv thiab cov khoom siv hluav taws xob sib tw nrog cov khoom siv hluav taws xob.
- Gas Injection Approach: Lub sij hawm sib xyaw ntawm cov cuab yeej cua dissolution tank sib txawv nrog rau kev txhaj tshuaj roj -pre- twj tso kua mis yuav tsum tau siv sij hawm sib tov tsawg, thaum tom qab - twj tso kua mis txhaj tshuaj yuav tsum tau ntev dua kev sib cuag. Koj tuaj yeem lees paub qhov tsim nyog rau kev txhaj tshuaj roj raws li koj qhov ntawm - cov txheej txheem txheej txheem ntawm qhov chaw thiab kev kho kom zoo, kom ntseeg tau tias cov khoom siv tau txais txiaj ntsig zoo tshaj plaws.
4. Kev txiav txim siab zoo ntawm tus nqi thiab tom qab-Kev Pabcuam Muag
- Tus Nqi Them Nqi: Ntawm qhov chaw ua tau raws li koj qhov peev xwm thiab kev kho mob, xaiv tus qauv sib xws raws li koj cov peev nyiaj. Thaum xav txog tus nqi yuav khoom, koj yuav tsum tsom mus rau lub sijhawm ntev - tus nqi khiav lag luam - cov khoom siv hluav taws xob tsawg thiab kev siv tshuaj lom neeg tuaj yeem txo qhov ntev - siv sijhawm ntev, uas yog tus nqi ntau dua - siv tau rau lub sijhawm ntev.
- Tom qab-Kev Pabcuam Muag: DAF cov cuab yeej siv tau ntev - lub sijhawm ua haujlwm, yog li zoo meej tom qab- kev muag khoom yog qhov tseem ceeb. Thaum xaiv, koj yuav tsum paub meej tias cov chaw tsim khoom tom qab- kev cog lus muag, xws li kev taw qhia kev teeb tsa, kev saib xyuas cov khoom siv, cov khoom seem thiab kev txhawb nqa, kom ntseeg tau tias txhua yam teeb meem tshwm sim thaum lub sijhawm ua haujlwm ntawm cov khoom siv tuaj yeem daws tau raws sijhawm, zam kev poob yam tsis tsim nyog.
