Nkhani Yogwiritsira Ntchito Malo Opangira Magetsi Odzipangira Okha mu Makampani Enaake a Mapepala ku Fujian

Kampani ina yogulitsa mapepala yomwe ili ku Fujian Province ndi imodzi mwa makampani akuluakulu opanga mapepala m'chigawochi komanso kampani yofunika kwambiri m'chigawochi yomwe ikuphatikiza kupanga mapepala akuluakulu ndi kuphatikiza kutentha ndi magetsi. Chiwerengero chonse cha ntchito yomanga pulojekitiyi chikuphatikizapo ma seti anayi a "ma boiler okhala ndi kutentha kwakukulu komanso kuthamanga kwamphamvu kwa mafuta ambiri ozungulira + ma turbine a nthunzi a 80 MW + ma jenereta a 80 MW," ndi boiler imodzi yomwe imagwira ntchito ngati gawo lothandizira. Ntchitoyi ikuchitika m'magawo awiri: gawo loyamba lili ndi ma seti atatu a zida zomwe zatchulidwazi, pomwe gawo lachiwiri limawonjezera seti imodzi yowonjezera.

Kusanthula khalidwe la madzi kumachita gawo lofunika kwambiri pakuwunika boiler, chifukwa khalidwe la madzi limakhudza mwachindunji magwiridwe antchito a boiler. Kuipa kwa madzi kungayambitse kusagwira bwino ntchito, kuwonongeka kwa zida, komanso ngozi zomwe zingachitike kwa ogwira ntchito. Kugwiritsa ntchito zida zowunikira khalidwe la madzi pa intaneti kumachepetsa kwambiri chiopsezo cha zochitika zokhudzana ndi chitetezo cha boiler, motero kuonetsetsa kuti makina a boiler akugwira ntchito bwino komanso mokhazikika.

Kampaniyo yagwiritsa ntchito zida zowunikira ubwino wa madzi ndi masensa ofanana opangidwa ndi B.OQUMwa kuyang'anira magawo monga pH, conductivity, oxygen yosungunuka, silicate, phosphate, ndi sodium ions, zimaonetsetsa kuti boiler ikugwira ntchito bwino komanso mokhazikika, zimawonjezera nthawi yogwira ntchito ya chipangizocho, komanso zimatsimikiza kuti nthunzi ndi yabwino.

Zogulitsa Zogwiritsidwa Ntchito:
Chowunikira pH cha pa intaneti cha pHG-2081Pro
Chowunikira Mayendedwe a Pa intaneti cha DDG-2080Pro
GALU-2Chowunikira cha Oxygen Chosungunuka pa Intaneti cha 082Pro
Chowunikira Silikate cha Paintaneti cha GSGG-5089Pro
Chowunikira cha Phosphate cha LSGG-5090Pro Paintaneti
Chowunikira cha DWG-5088Pro cha Sodium Ion cha pa Intaneti

pH: pH ya madzi a boiler iyenera kusungidwa mkati mwa mulingo winawake (nthawi zambiri 9-11). Ngati ili yotsika kwambiri (yokhala ndi asidi), idzawononga zigawo zachitsulo za boiler (monga mapaipi achitsulo ndi ng'oma za nthunzi). Ngati ili yokwera kwambiri (yokhala ndi alkaline kwambiri), ingayambitse kuti filimu yoteteza pamwamba pa chitsulo igwe, zomwe zimapangitsa kuti alkaline iwonongeke. pH yoyenera ingalepheretsenso kuwonongeka kwa carbon dioxide yaulere m'madzi ndikuchepetsa chiopsezo cha kukula kwa mapaipi.

Kuyenda kwa madzi: Kuyenda kwa madzi kumasonyeza kuchuluka kwa ma ayoni osungunuka m'madzi. Kuchuluka kwa madzi kukakhala kwakukulu, zinyalala zambiri (monga mchere) zimapezeka m'madzi. Kuyenda kwa madzi kwambiri kungayambitse kukula kwa boiler, dzimbiri mwachangu, komanso kungakhudze ubwino wa nthunzi (monga kunyamula mchere), kuchepetsa mphamvu ya kutentha, komanso kuyambitsa ngozi monga kuphulika kwa mapaipi.

Mpweya wosungunuka: Mpweya wosungunuka m'madzi ndiye chifukwa chachikulu cha kuwonongeka kwa mpweya m'zitsulo za boiler, makamaka m'makina osungira mpweya ndi makoma ozizira ndi madzi. Zingayambitse kupangika kwa dzenje ndi kucheperachepera pamwamba pa chitsulo, ndipo nthawi zina, kutayikira kwa zida. Ndikofunikira kuwongolera mpweya wosungunuka pamlingo wotsika kwambiri (nthawi zambiri ≤ 0.05 mg/L) kudzera mu chithandizo cha kuchepa kwa mpweya (monga kuchepa kwa mpweya ndi kuchepa kwa mpweya m'madzi).

Silicate: Silicate imakonda kusinthasintha ndi nthunzi pansi pa kutentha kwakukulu ndi kupanikizika, zomwe zimayikidwa pa masamba a turbine kuti apange silicate scale, zomwe zimachepetsa kugwira ntchito bwino kwa turbine komanso zimakhudzanso magwiridwe antchito ake otetezeka. Kuyang'anira silicate kumatha kuwongolera kuchuluka kwa silicate m'madzi a boiler, kuonetsetsa kuti nthunzi ili bwino, komanso kupewa kukula kwa turbine.

Muzu wa phosphate: Kuonjezera mchere wa phosphate (monga trisodium phosphate) m'madzi ophikira kumatha kuchitapo kanthu ndi ma calcium ndi magnesium ion kuti apange ma phosphate ion ofewa, zomwe zimalepheretsa kupangika kwa hard scale (monga, "chithandizo chopewera phosphate scale"). Kuyang'anira kuchuluka kwa muzu wa phosphate kumaonetsetsa kuti umakhalabe mkati mwa mulingo woyenera (nthawi zambiri 5-15 mg/L). Kuchuluka kwambiri kungayambitse kuti muzu wa phosphate unyamulidwe ndi nthunzi, pomwe kuchuluka kochepa kwambiri sikungalepheretse kupangika kwa scale.

Ma ayoni a Sodium: Ma ayoni a Sodium ndi ma ayoni odziwika bwino omwe amalekanitsidwa ndi mchere m'madzi, ndipo kuchuluka kwawo kumatha kuwonetsa molakwika kuchuluka kwa madzi a boiler ndi momwe mchere umayendera ndi nthunzi. Ngati kuchuluka kwa ma ayoni a sodium kuli kokwera kwambiri, zimasonyeza kuti madzi a boiler ndi okhuthala kwambiri, zomwe zimayambitsa kukulira ndi dzimbiri; ma ayoni a sodium ochulukirapo mu nthunzi angayambitsenso kuchuluka kwa mchere mu turbine ya nthunzi, zomwe zimakhudza magwiridwe antchito a zida.
