Nyaya Yechikumbiro yeSimba reKuzvimiririra Wega mune Imwe Mapepa Indasitiri muFujian

Imwe indasitiri yemapepa ine chikwereti chekambani inowanikwa muFujian Province nderimwe remabhizinesi makuru ekugadzira mapepa mudunhu uye bhizinesi rakakosha redunhu rinobatanidza kugadzira mapepa kwakakura nekusanganiswa kupisa uye kugadzira magetsi. Huwandu hwekuvaka hwepurojekiti iyi hunosanganisira maseti mana e "630 t/h high-temperature uye high-pressure multi-fuel circulating fluidized bed boilers + 80 MW back-pressure steam turbines + 80 MW jenareta," ine bhaira rimwe rinoshanda sechinhu chekuchengetedza. Iyo purojekiti inoitwa muzvikamu zviviri: chikamu chekutanga chine matatu seti ezvirongwa zvambotaurwa, nepo chikamu chechipiri chinowedzera imwe seti.

Ongororo yemhando yemvura inoita basa rakakosha mukuongorora bhailer, sezvo mhando yemvura ichikanganisa kushanda kweboiler. Hunhu hwemvura husina kunaka hunogona kukonzera kusashanda zvakanaka, kukuvara kwemidziyo, uye njodzi dzinogona kuitika kune vashandi. Kuitwa kwezviridzwa zvepamhepo zvekutarisa zvemhando yemvura zvinoderedza zvakanyanya njodzi yezviitiko zvekuchengetedza zvine chekuita neboiler, nekudaro kuve nechokwadi chekushanda kwakachengeteka uye kwakagadzikana kweiyo boiler system.

Iyo kambani yakatora maturusi ekuongorora emhando yemvura uye anofananidza masensa anogadzirwa naBOQU. Nekutarisa ma parameter akadai se pH, conductivity, yakanyungudika okisijeni, silicate, phosphate, uye sodium ions, inova nechokwadi chekuchengetedza uye kugadzikana kushanda kwebhailer, inowedzera hupenyu hwesevhisi yemidziyo, uye inovimbisa kunaka kweutsi.

pH kukosha: Iyo pH yemvura yeboiler inoda kuchengetedzwa mukati meimwe nhanho (kazhinji 9-11). Kana yakanyanya kuderera (acidic), inoshatisa zvikamu zvesimbi zvebhailer (senge pombi dzesimbi nemadhiramu ehutsi). Kana yakanyanya kuwanda (yakasimba alkaline), inogona kuita kuti firimu rinodzivirira riri pamusoro pesimbi ridonhe, zvichiita kuti alkaline corrosion. Iyo pH yakakodzera inogona zvakare kuvharidzira kukanganisa kwemahara carbon dioxide mumvura uye kuderedza njodzi yekukwira kwepombi.

Conductivity: Conductivity inoratidza huwandu hwehuwandu hweiyoni yakanyungudika mumvura. Iyo yakakwirira kukosha, iyo yakawanda tsvina (yakadai semunyu) inowanikwa mumvura. Kunyanya kukwirisa conductivity kunogona kutungamira kune boiler kuyera, kukurumidza kuita ngura, uye kunogona kukanganisa hunhu hwehupfu (senge kutakura munyu), kuderedza kupisa kwemafuta, uye kutokonzera zviitiko zvekuchengetedza sekuputika kwepombi.

Okisijeni yakanyungudika: Okisijeni yakanyungudika mumvura ndiyo honzeri huru yekuora kweokisijeni yesimbi dzebhailer, kunyanya muhupfumi uye madziro akatonhodzwa nemvura. Inogona kutungamirira kugomba uye kutetepa kwesimbi, uye mumatambudziko akaoma, midziyo inodonha. Izvo zvinodiwa kudzora okisijeni yakanyungudika pamwero wakaderera zvakanyanya (kazhinji ≤ 0.05 mg / L) kuburikidza nekurapa deaeration (senge thermal deaeration uye makemikari deaeration).

Silicate: Silicate inowanzoitika kuvhuvhuta nemhepo pasi pekushisa kwakanyanya uye kudzvanywa, ichiisa pane turbine blades kuti igadzire silicate sikero, iyo inoderedza turbine kunyatsoshanda uye kunyange kukanganisa kushanda kwayo kwakachengeteka. Monitoring silicate inogona kudzora iyo silicate yemukati mumvura yeboiler, kuve nechokwadi chemhando yeutsi, uye kudzivirira turbine kuyera.

Phosphate mudzi: Kuisa phosphate munyu (senge trisodium phosphate) kumvura yekuboiler kunogona kuita ne calcium ne magnesium ions kuti iite soft phosphate precipitates, kudzivirira kuumbwa kwekuoma (kureva, “phosphate scale prevention treatment”). Kutarisisa kuwanda kwe phosphate mudzi kunoita kuti irambe iri mukati mehumwe hunoenderana (kazhinji 5-15 mg/L). Kunyanya kuwanda kwemazinga kunogona kutungamira kumidzi yephosphate kutakurwa nemhepo, nepo mazinga akanyanya kuderera anotadza kudzivirira nemazvo kuumbwa kwechiyero.

Sodium ions: Sodium ions inowanzo patsanurwa munyu mumvura, uye zvirimo zvinogona kuratidza zvisina kunanga dhigirii remvura yekuboiler uye mamiriro emunyu anotakurwa nehutsi. Kana iyo yakasanganiswa sodium ions yakanyanyisa, inoratidza kuti mvura yebhailer yakanyanyisa, iyo inowanzokonzera kuwedzera uye kuora; yakawandisa sodium ions muutsi inozotungamira mukuunganidzwa kwemunyu mumhepo turbine, zvichikanganisa mashandiro emidziyo.
