Chav tsev ua ke daim ntawv ntawm cov koob tshuaj feem ntau yog nyob ntawm lub peev xwm ntawm chav tsev, kev teeb tsa ntawm lub boiler (ib txheej rau ob lub cub tawg lossis ib txheej rau ib lub qhov cub, thiab lwm yam), qib ntawm automation (tsis siv neeg lossis phau ntawv tswj. ), thiab xaiv hom tshuaj twj tso kua mis (AC Los yog tributary lub cev muaj zog, imported los yog domestic twj tso kua mis) flexibly tsim units ntawm ntau yam ntaub ntawv, uas yog ntsia rau hauv paus. Lub Hoobkas tsim ua tiav cov khoom siv no zoo heev txo cov haujlwm ntawm kev tsim thiab kev teeb tsa ntawm qhov chaw thiab muaj kev cuam tshuam zoo rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm tag nrho lub tshuab. Thiab nyob rau ntawm qhov chaw ua haujlwm muab kev ntseeg tau zoo.
Kev faib tawm
1. Boiler dej ntxiv rau phosphate system:
Cov txheej txheem kev npaj ntawm cov tshuaj phosphate qhia tau hais tias trisodium phosphate yog ncaj qha ntxiv rau hauv lub tank tov rau kev teeb tsa, thiab 4m3 dissolving tank kuj tuaj yeem teeb tsa, thiab lub twj tso kua mis infusion thawj zaug thiab nplawm, thiab tom qab ntawd nkag mus rau hauv lub tank tov.
Ntxiv nrog rau kev tswj hwm phau ntawv, kev tswj hwm ntawm cov nyiaj phosphate ntxiv tuaj yeem tswj tau: raws li cov qauv ntsuas ntawm phosphate rooj ntawm boiler dej, thiab cov zis tom qab kev ua tiav los ntawm microcomputer, tus nqi ntawm phosphate twj tso kua mis. yog tswj kom ua tiav lub hom phiaj ntawm kev siv tshuaj tsis siv neeg.
2. Feedwater thiab condensate ammonia ntxiv qhov system:
Ntxiv nrog rau kev npaj ntawm phau ntawv, kev npaj ntawm ammonia kua kuj tuaj yeem tswj tau: thaum cov kua theem ntawm cov kua tank qis dua li cov nqi teev, lub solenoid valve ntawm cov dej condensed inlet tau qhib rau cov kua dej siab thiab kaw. , thiab cov ntsuas hluav taws xob tau teeb tsa rau ntawm qhov hluav taws xob cov kav dej ntawm cov kua tank Thaum lub siab yog ± 1, uas yog sib npaug rau tus nqi conductivity ntawm 450 us / cm2, lub ammonia inlet valve tau kaw kom tiav cov txheej txheem xa tawm.
Ntxiv nrog rau kev tswj xyuas phau ntawv, kev tswj hwm ntawm ammonia ntxiv cov nyiaj kuj tuaj yeem tswj tau: raws li cov qauv ntsuas ntawm cov khoom siv hluav taws xob (lossis PH tus nqi) ntawm cov dej pub, thiab cov zis tom qab kev ua tiav los ntawm microcomputer, ammonia ntxiv tus nqi. ntawm ammonia ntxiv twj tso kua mis yog tswj kom mus txog qib tsis siv neeg dosing. Lub hom phiaj.
3. Boiler dej phosphate coordination tswj system:
Nyob rau hauv lub peev xwm loj lub nruas boilers nrog cov dej demineralized raws li cov dej ua kom zoo nkauj, txawm tias cov dej boiler tuav cov nqi pH uas tsim nyog, nws tiv thaiv kev tsim ntawm NaOH dawb thiab muaj ob qho tib si los tiv thaiv corrosion thiab tiv thaiv kev ua haujlwm. Qhov no yog lub hom phiaj ntawm kev sib koom ua ke ntawm boiler dej phosphate. , Raws li kev ua kom ntseeg tau tias cov dej boiler PH thiab PO3- ua tau raws li kev cai lij choj, cov dej zoo uas cov dej boiler tsis muaj NaOH dawb yog ua tiav los ntawm kev sib xyaw ntawm Na3PO4 ntxiv rau Na2HPO4 lossis Na3PO4 ntxiv rau NaOH rau lub tshuab raj. Ob tug qauv Kev xaiv ntawm cov dej boiler feem ntau yog txiav txim siab los ntawm cov dej zoo ntawm lub boiler, thiab qhov kom muaj nuj nqis ntawm cov mis - uas yog, Na / PO4 ratio (R-value) yog tau los ntawm kev ntsuas PH thiab PO{{14} } thiab saib lub rooj.
