Njira yolondola ndi njira zowonjezera mankhwala othandizira

Cholinga cha kuphatikiza kwamankhwala ndikuwonetsetsa kuti mphamvu ya mankhwala yomwe ili pamalo osalala komanso kukhalabe okhazikika. Chifukwa chake, malo a dosing ndi njira ya dosing amatha kusankhidwa moyenerera kutengera mawonekedwe a ore, chikhalidwe cha wothandizirayo ndi zomwe zimafunikira.
1. Malo a Dosing
Kusankha kwa malo a dosing kumakhudzana ndi kugwiritsa ntchito ndikusungunuka kwa wothandizirayo. Nthawi zambiri, adventi wapakatikati amawonjezeredwa pamakina opera, kuti athetse zovuta za "ma ion" omwe amalephera "omwe amachita ngati kutsegula kapena zoletsa. Zoletsa ziyenera kuwonjezeredwa pamaso pa osonkhanitsa ndipo nthawi zambiri amawonjezeredwa pamakina opukusira. Woyambitsa ntchito nthawi zambiri amawonjezeredwa ku thanki yosakanikirana ndikusakanikirana ndi slurry mu thanki kwa nthawi yayitali. Wotolera ndi wotsatsa amawonjezeredwa ku tanki yosakaniza ndi tank kapena makina owombera. Pofuna kupititsa patsogolo kufalikira ndikubalalitsa kwa otsetsereka (monga cresol wakuda ufa, ufa woyera, malasha, etc.) nthawi zambiri imawonjezeredwa makina opera.
Njira Yodziwika Yogwirizana ndi iyi:
.
.
Kuphatikiza apo, kusankha kwa malo a dosing ayeneranso kuganizira mtundu wa ore ndi zina. Mwachitsanzo. Kuphatikiza apo, makina owombera a cell amodzi amaikidwa muzomera zopukutira kuti mubwezeretse zosungunuka. Pofuna kuwonjezera nthawi yochita nawoto, ndikofunikira kuwonjezera wothandizirayo ku makina opera.

2. Njira ya Dosing
Kutulutsa ma flotation kumatha kuwonjezeredwa munthawi imodzi kapena m'matumba.
Kuphatikiza kwa nthawi imodzi kumatanthauza kuwonjezera wothandizira wina ku slurry nthawi imodzi asanabwereke. Mwanjira imeneyi, kuchuluka kwa wothandizirayo pamalo ena ogwiritsira ntchito ndi apamwamba, mphamvu zake ndi zazikulu, ndipo kuphatikiza ndizosavuta. Nthawi zambiri, kwa iwo omwe amasungunuka mosavuta m'madzi, sadzawombedwa ndi makina a thovu. Kwa othandizira (monga Soda, laimu, ndi zina) zomwe sizingachitike mosavuta ndikukhala zopanda nzeru, mlingo umodzi nthawi zambiri umagwiritsidwa ntchito.
Mlingo wa batch umatanthawuza kuwonjezera mankhwala ena mumitundu ingapo pakusinthasintha. Nthawi zambiri, 60% mpaka 70% ya ndalama zonse zimawonjezeredwa musanayambe maluwa, ndipo otsalawo 30% amawonjezeredwa m'malo oyenera m'matanga angapo. Mwanjira imeneyi kupangira mankhwala m'matumba kumatha kukhalabe ndi chidwi cha mankhwala ndi chingwe chogwiritsira ntchito chambiri komanso thandizo kuti chithandizireni.
Pazochitika zotsatirazi, zowonjezera za batch ziyenera kugwiritsidwa ntchito:
.
(2) Othandizira omwe ndi osavuta kuchitira kapena kuwola mu slurry. Monga kaboni dayokisi, sulufule dioxide, etc., ngati atangowonjezedwa pokhapokha, zomwe zimalephereka mwachangu.
(3) Mankhwala omwe Mlingo wake umafunikira kuwongolera kosatha. Mwachitsanzo, ngati kukhazikika kwa sodium sulfide kuli kwambiri, kusankha komwe kumatayika.
