Jirgin Yawan Maimaita na Tsakiyar Zafiya na IEE-Business Dukkanta Da Jirgin Yawan Maimaita na Kammala Tashin Zafiya

Duk da duka abubuwa na hankali da mutanen gida suna da wani karamin abubuwa da gaso masu shiga. Yawan wannan abubuwan depenchi ne a cikin wani abubuwan ruwa da lokacin.
Zan iya bayar da sabbin da ya fi kyau a kan sake tsara raw water?
Raw water da yake fito daga baya-bayan abubuwan ruwa suna da salt masu shiga da abubuwan ruwa mai sauya ko masu shiga. Ya kamata a fada salt masu shiga a kan ruwa idan kana yi amfani da ita a boiler.
Saboda-

1. Shiga salt masu shiga da abubuwan ruwa mai sauya zai tsara scale a jamiyar kofin heat-exchangers, kuma zai faru ci gaba da pressure da thermal stress (daga ba daidai tsari a kan heat exchange a kofin heat-exchanger) a cikin heat-exchangers, wanda zai iya haifar da yanayi da shawarar da suka shafi boilers.

2. Salt masu shiga masu hankali suka iya haifar da wani abubuwan boiler da ruwa ta fito, kuma tana sa shiga jihohi.

3. Yanayi da shawarar da suka shafi turbine blades yana iya faru.

Saboda haka, boiler feed water treatment ya kamata don fada abubuwan ruwa masu shiga da abubuwan ruwa mai sauya daga ruwa idan kana yi amfani da ita a kan boiler.

Arrangements for Boiler Feed Water Treatment

Don samun tasirin ruwa da za a yi amfani da ita a kan boiler, ba a fada abubuwan ruwa, akwai nau'o'i biyu da ake amfani da su. Waɗannan sun hada:

1. Demineralization plant (D M plant)

2. Reverse Osmosis plant (R O plant)

Demineralization plant tana amfani da hanyar kimiyar don fada salt masu shiga a kan raw water. Amma reverse osmosis plant tana amfani da hanyar kimya mai zurfi don fada salt masu shiga. Idan kana fito raw water zuwa waɗannan plants, ana yi sand filtration tare da filters daban-daban.

Daga baya-bayan waɗannan plants, akwai deaerators biyu, wadanda suke fada oxygen masu shiga a kan ruwa, saboda wasu traces of oxygen suke iya haifar da boiler tubes da suke sa shawarar da su.
Kula-kulan arrangements da kuma equipment masu mulkin waɗannan plants an bayyana a nan.

Demineralization Plant

Aiki na demineralization plant shine fada salt masu shiga tare da hanyar ion exchange (kimya) da kuma karɓar ruwa mai sauƙi don boiler.

Salt masu shiga ruwa shine chloride, carbonates, bi-carbonates, silicates da phosphates of sodium, potassium, iron, calcium da magnesium.
A cikin D M plant akwai resin uku na nufin da ake amfani da su don boiler feed water treatment process –

1. Cation exchange resin

2. Anion exchange resin

3. Mixed Bed resin

1. 
   

1. Resins suna da kayan abubuwa (kafin da ya fi son polymer da yawan maza mai yawa) da ake amfani da su don haifar da salt da kuma fada su tare da hanyar kimya.

2. Kamar yadda aka sani, cation exchange resin, tana haifar da cation, kuma anion exchange resin, tana haifar da anions tare da salt masu shiga a cikin hard-water.

Cation Exchange Resin

Saboda H2SO4, H2CO3 suna haifar da su.
Ana fada Na+ amma ruwa ta zama mai asidi.

Anion Exchange Resin

Wannan haka ana fada Cl– kuma asidi na ruwa.
Matsala na H2SO4 na da shi.

Mixed Bed Resins

Waɗannan mixed bed resins suna amfani da su a Demineralization plant na boiler feed water treatment, don fada ions (musamman Na+ da SO32-) wadanda suke duba a kan ruwa bayan na yi hanyar purification.

Degasser

Aiki na degasser tower shine fada carbonate ions tare da hanyar tsara carbon-di-oxide. A cikin degasser tower, stream of water tana fito daga fushi, kuma air tana taka daga kasa zuwa fushi. A cikin pressure na air, carbonic acid (H2CO3) wanda yake a kan ruwa tana koyar da H2
