Nyaya Yekushandisa Chigadzirwa Chemagetsi Chega Muindasitiri Yepepa Yakati muFujian

Imwe kambani ine mutoro wemari shoma iri muFujian Province ndeimwe yemakambani makuru ekugadzira mapepa mudunhu iri uye ikambani huru yedunhu iri inobatanidza kugadzira mapepa makuru pamwe chete nekugadzira kupisa nemagetsi. Huwandu hwese hwekuvaka kwepurojekiti iyi hunosanganisira maseti mana e "630 t/h mabhoyila emubhedha ane fluidized fluidized bed boilers ane 80 MW back-pressure steam turbines + 80 MW generators," ine bhoyila imwe chete inoshanda se backup unit. Chirongwa ichi chinoitwa muzvikamu zviviri: chikamu chekutanga chine maseti matatu emidziyo yataurwa pamusoro apa, nepo chikamu chechipiri chichiwedzera seti imwe yekuwedzera.

Kuongorora hunhu hwemvura kunoita basa rakakosha mukuongorora boiler, sezvo hunhu hwemvura huchikanganisa zvakananga mashandiro eboiler. Hunhu husina kunaka hwemvura hunogona kukonzera kusashanda zvakanaka kwekushanda, kukuvara kwemidziyo, uye njodzi dzinogona kuchengetedzeka kune vashandi. Kushandiswa kwezvishandiso zvekutarisa hunhu hwemvura online kunoderedza zvakanyanya njodzi yezviitiko zvekuchengetedza zvine chekuita neboiler, nokudaro zvichiita kuti boiler system ishande zvakanaka uye yakachengeteka.

Kambani iyi yakashandisa zvishandiso zvekuongorora hunhu hwemvura uye masensa ekufananidza akagadzirwa neBOQUNekutarisa maparamita akadai sepH, conductivity, oxygen yakanyungudutswa, silicate, phosphate, uye sodium ions, zvinoita kuti bhaira rishande zvakachengeteka uye zvakagadzikana, rinowedzera hupenyu hwebasa remuchina, uye rinovimbisa kunaka kwemhepo inopfuta.

pH kukosha: pH yemvura yebhoyila inofanira kuchengetedzwa mukati mehuwandu hwakati (kazhinji 9-11). Kana yakaderera zvakanyanya (ine acid), ichaparadza zvikamu zvesimbi zvebhoyila (senge mapaipi esimbi nemadhiramu emhepo). Kana yakakwira zvakanyanya (ine alkaline zvakanyanya), inogona kukonzera kuti firimu rekudzivirira riri pamusoro pesimbi riwire pasi, zvichikonzera ngura yealkaline. pH yakakodzera inogonawo kudzivirira ngura yecarbon dioxide yakasununguka mumvura uye kuderedza njodzi yekukwira kwepombi.

Kufambiswa kwemhepo: Kufambiswa kwemhepo kunoratidza huwandu hwese hwemaayoni akanyungudutswa mumvura. Kana kukosha kwacho kwakakwira, tsvina yakawanda (senge munyu) inowanikwa mumvura. Kufambiswa kwemhepo kwakanyanya kunogona kukonzera kukwira kweboiler, ngura nekukurumidza, uye kunogonawo kukanganisa hunhu hwemhepo (senge kutakura munyu), kuderedza kushanda zvakanaka kwekupisa, uye kutokonzera njodzi dzekuchengetedza dzakadai sekuputika kwemapaipi.

Okisijeni yakanyungudika: Okisijeni yakanyungudika mumvura ndiyo inonyanya kukonzera ngura yeokisijeni yesimbi dzeboiler, kunyanya muzvinhu zvinochengetedza ngura nemadziro anotonhorerwa nemvura. Izvi zvinogona kukonzera kutetepa kwesimbi, uye muzviitiko zvakakomba, kubuda kwemvura mumidziyo. Zvakakosha kudzora okisijeni yakanyungudika padanho rakaderera zvikuru (kazhinji ≤ 0.05 mg/L) kuburikidza nekurapa ngura (sekudzikira kwekupisa uye kudzikira kwemakemikari).

Silicate: Silicate inogona kuputika kana iine utsi hwemvura kana ichipisa zvakanyanya uye ichimanikidzwa, ichiisa pamashizha eturbine kuti igadzire silicate scale, izvo zvinoderedza kushanda zvakanaka kweturbine uye zvinotokanganisa kushanda kwayo kwakachengeteka. Kutarisa silicate kunogona kudzora huwandu hwesilicate mumvura yeboiler, kuona kuti utsi hwakanaka, uye kudzivirira kukura kweturbine.

Mudzi wephosphate: Kuwedzera phosphate salts (yakadai se trisodium phosphate) mumvura yekubikira kunogona kuita kuti calcium ne magnesium ions zvigadzire soft phosphate precipitates, zvichidzivirira kuumbwa kwe hard scale (kureva, "kurapa kwekudzivirira phosphate scale"). Kutarisa huwandu hwe phosphate mudzi kunoita kuti ugare uri mukati mehuwandu hwakaringana (kazhinji 5-15 mg/L). Mazinga akawandisa anogona kukonzera kuti phosphate mudzi utakurwe nemhepo, nepo mazinga akaderera zvakanyanya achikundikana kudzivirira scaling kuumbwa.

Maion eSodium: Maion eSodium ndiwo maion akajairika akaparadzaniswa nemunyu mumvura, uye huwandu hwawo hunogona kuratidza zvisina kunanga huwandu hwemvura yeboiler uye mamiriro emunyu unotakurwa nemhepo inopfungaira. Kana huwandu hwemaion eSodium hwakanyanya, zvinoratidza kuti mvura yeboiler yakanyanyisa, izvo zvinogona kukonzera kukora uye ngura; maion eSodium akawandisa mumhepo inopfungaira achaitawo kuti munyu uungane mumhepo inopfungaira, zvichikanganisa mashandiro emidziyo.
