Mamita ekudzikisa huwandu hwemagetsi ari mumutsetse ndiwo anochinja zvakanyanya kushandurwa kwesimba remagetsi mumagetsi panguva yekushanda kwemaindasitiri. Aya magauge ehungwaru matsva anobvumira vashandi kutarisa huwandu hwemagetsi panguva chaiyo, pamwe nemidziyo yakakosha inotarisa maitiro akaomarara emakemikari. Zvakakosha kuti vashandi vatarisane nematambudziko ekushanda sekutevera mitemo yakaoma yezvakatipoteredza. Tarisa mamiriro ezvinhu akadzama avanoshanda nawo kugadzirisa matambudziko akaomarara emaindasitiri uye kubvisa basa rakaoma asi rinodzokororwa.
Matambudziko Akakomba eUnyanzvi muDenitration
Kugadzirisa kuburitswa kwenitrogen oxide (NOx) hakusi nyore. Nitrogen oxide haigone kubviswa zvachose, zvisinei nemidziyo inopiswa nemarasha, inopiswa nemafuta kana kunyange biomass. Kugadziriswa kwekuburitswa kwemhepo nemazvo kwakabatana neSelective Catalytic Reduction (SCR) kana Selective Non-Catalytic Reduction (SNCR), umo ma reagents anowedzerwa mu flue gas stream kuti awedzere kuita zvimwe. Kunyange zvakadaro, kutarisa kwakarurama kwedosi remushonga munguva chaiyo kunosangana nematambudziko akawanda kubva mumamiriro ezvinhu akaomarara ekushanda. Kusarongeka kwekuyera kunogona kukonzera ammonia kutsvedza uye marara e reagents.
Lonnmeter inogadzira uye inogadzira mita yekuwanda kwemukatikuti pave nekuongororwa kwakawanda kwehuwandu hwevanhu kuti vasakanganiswa nekurapwa kwemhando dzakasiyana dzemasampuli. Kurapwa kwemhando dzakasiyana dzemasampuli kunonyanya kushandiswa pakuongorora nguva nenguva uye kufungidzira zvisina kunanga.mita yehuwandu hwepamhepoinokwanisa kuona kuchinja kudiki mukutarisa huwandu hwezvinhu kuti ibatsire kugadzirisa kwakanyatsojeka, zvichiita kuti maitiro ese ekubvisa tsvina agare akasimba uye achishanda zvakanaka.
Pamusoro pezvo, inoshandawo mukupa maparamita anoratidza mhando yekusanganisa, kuenderana kwe reagent uye mwero wekuyerera wakaenzana. Semuenzaniso, kusawirirana kwemvura yeurea kusvika pakunyungudika mumvura kunokanganisa reaction chemistry. Nekutarisa slurry zvakananga mupaipi, inline density mita inovimbisa kuti huwandu hunodiwa hunochengetwa kubva pakuchengetwa kusvika pakuiswa jekiseni, zvichideredza njodzi yekusashanda zvakanaka kweprocess kana kusatevedzera nharaunda.
Mamita eKuwanda Kwemaindasitiri Anokurudzirwa
Kuvandudza Otomatiki muDenitration uye Kuvimbika kweSisitimu
Mazuva apera apo vashandi vemafekitori vaifanira kuvimba nemabasa emaoko kuti vagadzirise reagent injection. Mamita emazuva ano e inline density anobatanidzwa zvakanaka muDistributed Control Systems (DCS) kana Programmable Logic Controllers (PLC), zvichibvumira kuti pave nemhinduro dzinoshanda otomatiki. Kana kuverenga kwe density kuchisiyana ne preset range, system inogadzirisa otomatiki reagent flow rate kana kuderedza mhinduro sezvinodiwa. Izvi hazvingoderedzi mutoro wevashandisi chete asiwo zvinobvisa kunonoka kunokonzerwa nekuita sarudzo kwevanhu.
Zvakakosha kuyera huwandu hwemakemikari mukugadzirisa pamwe chete kwekubvisa sulfurization nekubvisa nitration, uko mvura ye lime slurry ne ammonia zvinoshandiswa panguva imwe chete. Kutarisa huwandu hwemvura idzi mbiri ndiko kunodiwa kuti desulfurization nekubvisa nitration zvishande zvakanaka. Kubatana uku kunobatsira kudzivirira matambudziko akajairika se sedimentation mumapaipi e limestone kana kuwandisa kwe ammonia, zvese izvi zvinogona kukonzera kudzimwa kunodhura kana kugadziriswa.
Pamusoro pezvo, mamita akadaro akasimba e inline density anodzivirira mamiriro akaoma mumagetsi. Kuti magadzirirwo akakosha agone kutsungirira tembiricha yakakwira nekumanikidzwa, akakodzera kubata makemikari anoparadza mumamiriro ezvinhu akaoma senge flue gas denitration system.
Mashandisirwo eInline Density Meters muCoal-Fired Power Plant
Kazhinji, mafekitori emagetsi anoshandiswa nemarasha ari kunetseka nekusashanda zvakanaka pakuyera huwandu hwemagetsi pamwe nematambudziko ehunyanzvi anoenderana nawo, anosanganisira asi kwete kungogumira pakuvharika kwepombi, kutsvedza kweammonia uye kugadzirisa kunogona kuitika. Forogo inline density meter ndiyo chishandiso chakakodzera chekubatanidza ammonia injection line uye limestone slurry system.
Mhedzisiro yacho yakachinja. Kutarisa huwandu hwemvura panguva chaiyo kwakaita kuti chirimwa ichi chigone kugadzirisa reagent dosing nemazvo zvisati zvamboitika. Ammonia slip levels yakaderera neanopfuura 90%, ukuwo NOx reduction efficiency yakadarika 92%. Limestone slurry, iyo yaimbokonzera scaling uye blockages, yakaramba iri pahuwandu hwakakwana, ichibvisa kugadziriswa kusina kurongwa uye kuderedza nguva yekushanda ne20%. Kuvandudzwa uku hakuna kungounza chirimwa ichi kutevedzera mitemo yezvakatipoteredza chete asiwo kwakaderedza mari yekushanda ne15%.
Nei Mamita eInline Density Achikosha?
Chinosiyanisa mita dze inline density nedzimwe mhinduro dzekutarisa ndechekuti dzinoshanda nesimba uye dzinochinjika. Hadzingogumiri pakubvisa hunitration chete; mashandisirwo adzo anosvika kune chero nzira yeindasitiri inoda manejimendi chaiyo yemvura. Mumamiriro ezvinhu emagetsi, izvi zvinosanganisira masisitimu ekubvisa sulfurization, kurapwa kwemvura yakasviba, uye mashandiro ekubatanidza mafuta. Kugona kwavo kupa data renguva chaiyo, rakarurama, uye rinoshanda kunoita kuti vave musimboti wekugadzirisa maitiro emazuva ano.
Nekushandisa zvishandiso izvi, mafekitori emagetsi anogona kuwana mwero wekudzora maitiro waisambowanikwa kare. Mabhenefiti acho anowedzera kupfuura kutevedzera mitemo nekushanda zvakanaka; anosanganisirawo kuvandudzwa kwenguva refu yemidziyo, kudzikiswa kwemari yekugadzirisa, uye kusimba kwakawedzerwa. Kune vanoshanda vanokoshesa mashandiro uye mutoro wezvakatipoteredza, inline density metres haisi kungodyara chete—inokosha.
Mhedziso
Kushandiswa kwemamita ekudzikisa huwandu hwemagetsi mumagetsi ekudzikisa huwandu hwemagetsi kunoratidza kuti tekinoroji yepamusoro inogona kushandura sei mashandiro emaindasitiri. Nekugadzirisa matambudziko akadai se reagent consistency, ammonia slip, uye process automation, zvishandiso izvi zvinogonesa magwenya emagetsi kushanda zvakanaka, nenzira inochengetedza, uye inobatsira. Nhoroondo yavo yakaratidzwa mumashandisirwo chaiwo emagetsi inoratidza kukosha kwavo sechishandiso chakakosha mukurwisa NOx emissions. Kana uri kutsvaga kusimudzira mashandiro ako ekudzikisa huwandu hwemagetsi, hapana imwe nguva iri nani yekuongorora mukana wekuyera huwandu hwemagetsi mumagetsi.
