Txoj kev yooj yim tshaj plaws thiab zoo tshaj plaws los tswj koj tus kheej boiler yog kom muaj ib boiler lim dej nrog nplai inhibitor. Scale inhibitor ua haujlwm los ntawm kev tsim cov txheej tiv thaiv nyias ntawm cov dej-sab ntawm cov chaw hloov hluav taws xob mus rau tiv thaiv nplai txhim kho thiab corrosion.
Tom qab ntawd, ua li cas koj nres lub boiler nplai?
Scale formation yog tiv thaiv los ntawm:
- Pretreatment ntawm boiler make-up dej (siv dej softeners, demineralizers, thiab thim rov qab osmosis kom tshem tawm scale-forming minerals)
- Txoj haujlwm kho dej tsis tu ncua.
- Kev ua haujlwm zoo ntawm boiler blowdown.
Ib sab saum toj no, yuav ua li cas teev yog tsim nyob rau hauv boiler? Boiler nplai yog tshwm sim los ntawm impurities raug precipitated tawm ntawm dej ncaj qha rau ntawm tshav kub hloov chaw los yog los ntawm tshem tawm cov teeb meem nyob rau hauv dej tawm ntawm cov hlau thiab ua ib tug nyuaj thiab adherent. Scale yog tsim los ntawm cov ntsev uas muaj tsawg solubility tab sis tsis tag insoluble nyob rau hauv boiler dej.
Yog li ntawd, yuav ua li cas koj tshem tawm scale tsim?
Rau tshem tawm scale tsim Nyob rau hauv cov yeeb nkab dej ua los ntawm PVC tsuas yog sib tov ib co HCl nyob rau hauv cov dej cia tank thiab circulate dej rau 1 hr kom nws dissolves tag nrho cov dej. nplai thiab ntxuav cov yeeb nkab.
Dab tsi yog scale thiab sludge tsim nyob rau hauv boilers?
Kev ntsuas thiab sludge tsim hauv boilers . Thaum lawv cov concentrations ncav cuag saturation point, lawv raug pov tawm ntawm dej nyob rau hauv daim ntawv ntawm precipitates nyob rau hauv lub puab phab ntsa. boiler . Yog hais tias nag lossis daus tshwm sim nyob rau hauv daim ntawv ntawm xoob thiab slimy precipitate, nws yog hu ua sludge.

Dab tsi yog ob txoj hauv kev zoo rau pab pawg txhim kho kom tsis txhob ua haujlwm tsis zoo?
Txoj hauv kev feem ntau ntawm kev ua qhov no yog nrog cov ntsiab lus tsis meej pem, raws li Kev Pom Zoo, lossis yog ib feem ntawm pab pawg Cov Lus Txhais Ua tiav. Peb tuaj yeem ua qhov tsis xav tau kev ua haujlwm pom los ntawm kev tsim cov khoom rov qab ywj pheej (xws li Tus Neeg Siv Dab Neeg lossis Tus Tsim Txuj Ci) rau qhov xav tau ntawd
Yuav ua li cas yog qhov tsawg kawg nkaus pob zeb npog nyob rau hauv mm ntawm ib tug cam khwb cia nyob rau hauv qhov chaw pob zeb tso tawm tsam thiab mus tas li raug rau lub ntiaj teb?
Table-1: Yam Tsawg Npog Thickness rau Cast-in-Place Qhob Hom kev tsim ua vaj tse hla, hli Qhob nrum tiv thaiv thiab txuas mus tas li nrog hauv av 75 Pob zeb sib chwv nrog av lossis dej No. 19 txog No. 57 tuav 50 No. 16 bar thiab me dua 40
Yuav ua li cas kom tsis txhob condensation nyob rau hauv kuv lub cav roj?
Tib txoj kev uas yuav tshem tau cov condensation yog tsav lub tsheb ntev txaus kom cov roj kub txaus kom boil nws tawm. +1. Tsuas yog cua sov tau tshem ntawm condensation
Nyob rau hauv cov nroj tsuag twg photosynthesis tshwm sim nyob rau hauv qia es tsis nyob rau hauv nplooj?
1 Teb. Nyob rau hauv cov nroj tsuag photosynthesis tshwm sim nyob rau hauv chloroplasts. Chloroplast tuaj yeem nyob hauv lub hlwb ntawm cov txiv hmab txiv ntoo, stems, tab sis feem ntau ntawm tag nrho cov nplooj. Hauv qee qhov succulents (xws li cacti), lub ntsiab photosynthetic kev ua haujlwm yog txuam nrog lub qia
Yuav ua li cas tshwm sim thaum lub concentration ntawm qabzib nyob rau hauv cov dej sab nraum lub cell yog siab tshaj qhov concentration nyob rau hauv?
Yog hais tias qhov concentration ntawm qabzib nyob rau hauv dej sab nraud ntawm lub cell yog siab tshaj qhov concentration hauv, dej yuav nyiam tawm hauv lub cell los ntawm osmosis. c. Cov piam thaj yuav zoo li nkag mus rau hauv lub cell los ntawm osmosis
