1, Preprocessing thiab Batch Cleaning
Acid tov solub pas dej
Kev teeb tsa: Sib tov cov qib citric acid (los yog qib acetic acid) nrog dej hauv ib lub thawv loj ntawm qhov sib piv ntawm 1: 5, xyuas kom meej tias cov tshuaj npog tag nrho lub raj mis.
Soaking lub sij hawm: Me me anti alkali soaking rau 2-4 teev, hnyav anti alkali soaking yuav ncua mus rau 8-12 teev.
Qhov zoo: Batch processing txo cov nqi zog, thiab cov kua qaub tuaj yeem rov ua dua tshiab (yuav tsum tau ua kom muaj zog ntxiv).
Mechanical pab tu
Lub tshuab nqus dej siab siab: Siv 100-150bar siab rab phom dej los yaug hauv lub raj mis, ua ke nrog lub tshuab tig los txhim kho cov nyhuv.
Ultrasonic tu tshuab: haum rau zoo carving los yog nqaim lub qhov ncauj fwj. Muab lub khob ntim dej tso rau hauv lub tank ultrasonic thiab co rau 10-15 feeb kom tawg cov nplai tawv tawv.
2, Kev xaiv tus neeg saib xyuas kev tshaj lij
Industrial qib scale remover
Cov khoom pom zoo: Tus neeg saib xyuas tu muaj hydroxy acetic acid thiab amino sulfonic acid Cheebtsam (xws li Rust Oleum professional scale remover), diluted raws li cov lus qhia ua ntej siv.
Ceeb Toom: Hnav cov hnab looj tes tiv thaiv thiab tsom iav kom tsis txhob sib cuag nrog daim tawv nqaij.
Alkaline ntxuav kev pab
Cov xwm txheej siv tau: Yog tias cov roj stains sib xyaw hauv cov txheej txheem tiv thaiv alkali, lawv tuaj yeem raug kho nrog cov tshuaj alkaline tsis muaj zog (xws li sodium carbonate) ua ntej, thiab tom qab ntawd ntxuav nrog cov kua qaub.
3, Disinfection thiab ziab
Kev kho mob tua kab mob
Sodium hypochlorite tov: Sod nyob rau hauv 5% concentration tov rau 30 feeb los tua cov pwm uas yuav loj hlob thaum lub sij hawm ntev - cia.
Cov tshuaj tua kab mob kub kub kub: Siv cov khoom siv chav ua haujlwm (tshaj li 120 degree) ua haujlwm rau 10 feeb, tsim nyog rau cov zaub mov qib iav fwj.
Kev ziab sai sai
Centrifugal dehydrator: Muab lub raj mis ntxuav rau hauv lub centrifuge thiab dehydrate nws ntawm 3000 rpm rau 5 feeb.
Cov cua kub cua kom qhuav: Siv lub qhov cub kub ntawm 60-80℃kom qhuav rau 2-3 teev, kom tsis txhob muaj cov dej seem.
4, Cia thiab Tiv Thaiv
Moisture resistant cia
Khaws cov iav fwj upside down nyob rau hauv ib qho chaw qhuav thiab ventilated, nrog lub raj mis lub qhov ncauj ntawm downwards kom tsis txhob muaj cov tsub zuj zuj ntawm condensed dej.
Siv silica gel desiccant (500g ib cubic meter) thiab hloov tsis tu ncua.
Kev saib xyuas tsis tu ncua
Tshuab lub raj mis nrog cov cua compressed qhuav txhua lub hlis twg los tiv thaiv cov kab ya raws rov qab.
Lub tshuab nqus tsev kaw lub khob huv huv kom cais cov dej noo.
5, Kev tiv thaiv ib puag ncig thiab kev siv nyiaj txiag zoo
Kev kho dej khib nyiab
Acidic wastewater yuav tsum tau neutralized nrog sodium hydroxide rau pH 6-9 ua ntej tso tawm, los yog hu rau lub tuam txhab kev kho dej phwj rau kev rov ua dua.
kev tswj tus nqi
Ua ntej siv cov kua qaub citric acid rov qab siv dua (kwv yees li 5-8 yuan / kg), uas txuag tau ntau dua 30% ntawm cov nqi piv rau cov tshuaj ntxuav tu pov tseg.
cov kev ceev faj
Kev tiv thaiv kev nyab xeeb: Hnav khaub ncaws tiv thaiv thiab tiv thaiv lub ntsej muag thaum ua haujlwm muaj zog acids thiab alkalis, thiab muab cov chaw ntxuav qhov muag ntawm qhov chaw.
Kev soj ntsuam zoo: Kev tshuaj ntsuam xyuas tom qab ntxuav, paub meej tias tsis muaj qhov seem nrog pH daim ntawv xeem, los yog thim rov qab thiab saib xyuas cov cim dej.
