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:

  1. Pretreatment ntawm boiler make-up dej (siv dej softeners, demineralizers, thiab thim rov qab osmosis kom tshem tawm scale-forming minerals)
  2. Txoj haujlwm kho dej tsis tu ncua.
  3. 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.
