Dhoobada wasakhda ahi waa mid ka mid ah ilaha wasakhowga ah ee saliidda iyo gaaska. Si looga hortago wasakhowga deegaanka ee ay keento dhoobada qashinka ah waa in la daweeyaa. Marka loo eego xaaladaha kala duwan ee daaweynta iyo dheecaanka, waxaa jira habab badan oo lagu daweeyo dhoobada qashinka gudaha iyo dibaddaba. Daawaynta adagi waa mid ka mid ah hababka aadka loo isticmaalo, gaar ahaan ku habboon dhoobada qashinka ah ee aan ku habboonayn beerista dhulka.
1. Adkeynta dhoobada qodista qashinka
Daawaynta adagi waa in la geliyo saamiga saxda ah ee wakiilka daawaynta godka dhoobada wasakhda ah ee ka-hortagga jeexjeexa, si siman loogu qaso si waafaqsan shuruudaha farsamo ee qaarkood, oo loo beddelo qaybaha waxyeellada leh ee adag oo aan wasakhayn iyada oo loo marayo isbeddello jireed iyo kiimiko ah wakhti go'an.
Habka xisaabinta ee adkeynta dhoobada: wadarta wejiyada adag ka dib kala soocida dareeraha adag ee dareeraha sibidhka iyo macsarada, qalajiyaha, dhoobada qashinka ah ee laga soo saaro centrifuge, iyo xabag laga soo saaro haanta qashinka ah.
2. Farsamada MTC
U beddelashada dhoobada oo loo beddelo slurry sibidhka, oo loo soo gaabiyo farsamada MTC (Mud To Cement), ayaa ah tignoolajiyada hormoodka ah ee tignoolajiyada sibidhka. Slag MTC waxaa loola jeedaa in lagu daro slurry foornada qaraxa biyaha-demi, firfircooniye, kala firdhiye iyo wakiilada kale ee daawaynta ee slurry si loogu beddelo dareeraha sibidhka. Farsamadani waxay yaraynaysaa kharashka daawaynta ee qashinka qashinka waxayna sidoo kale yaraynaysaa kharashka sibidhka.
3. Kala soocida dareeraha adag ee kiimiko ahaan loo xoojiyay
Habka kala soocida dareeraha adag ee kiimikaad ahaan loo xoojiyey ayaa marka hore fuliya xasiloonida kiimikada iyo daawaynta qulqulka ee dhoobada qashinka qodista, waxay xoojisaa awoodda kala saarista dareeraha adag ee farsamada, waxayna u beddeshaa qaybaha waxyeelada leh ee dhoobada qashinka ah walxo aan khatar ahayn ama aan waxyeello lahayn ama waxay yaraynaysaa heerka dheecaanka. inta lagu jiro xasiloonida kiimikada iyo daaweynta qulqulka. Dabadeed, dhoobada wasakhda ah ee aan xasiloonayn iyo roodhida ayaa lagu shubaa centrifuge-ka dareeraha qodista nooca turbo. Wareegga wareega ee dareeraha dareeraha ee qodista iyo kicinta ay dhaliso durbaanka wareegta ayaa si wadajir ah u soo saara saameyn firfircoon oo dhamaystiran, taas oo saameyn xooggan ku leh sedimentation-ka semi-static ee centrifuge, oo ogaanaya kala-soocidda dareeraha adag, si biyaha xorta ah inta u dhaxaysa qaybaha floc iyo qayb ka mid ah biyaha intermolecular waxaa lagu kala saaraa centrifugation. Ka dib marka la kala saaro dareeraha adag, qadarka wasakhaysan (sludge) ayaa la dhimay, mugga ayaa si weyn loo dhimay, kharashka daaweynta aan waxyeellada lahayn ayaa labanlaabantay.
4. Ku daadinta dhoobada qashinka ee qodista xeebaha
(1) Daaweynta dhoobada biyaha ku salaysan
(2) Daaweynta dhoobada saliidda
Habka socodka ee daawaynta aan soo degin ee dhoobada
(1) Unug ururinta. Dhoobada qodista qashinka waxay ka gashaa qalabka wax lagu koontaroolo ee birta ah, waxaana lagu daraa biyaha si loo qaso.
(2) Unug kala soocida dareeraha adag. Si loo yareeyo biyaha iyo wasakhda keega dhoobada ah, waxaa lagama maarmaan ah in lagu daro wakiilada daaweynta oo si isdaba joog ah u walaaq oo dhaq.
(3) Qaybta daaweynta biyaha wasakhda. Waxa ku jira walxaha adag ee la hakiyey ee biyaha ay kala sooceen centrifugation waa sarreeyaa. Walxaha adag ee biyaha ku jira ayaa laga saaraa iyada oo loo marayo nidaamka sed-burinta sabbeynta hawada iyo nidaamka sifaynta si loo yareeyo waxa ku jira maadada organic ee biyaha wasakhda ah, ka dibna loo galo nidaamka osmosis-ka ee daaweynta diiradda.
