Inline density metres ndiyo inoshandura mutambo we denitration mumagetsi emagetsi panguva yemaindasitiri maitiro. Aya majeji ehungwaru akangwara anobvumira vashandisi kuti vatarise density munguva-chaiyo, zvakare yakakosha michina inogadzirisa yakaoma makemikari maitiro. Izvo zvakakosha kuti vashandisi vatarisane nematambudziko ekushanda sekutarisa zvakanyanya uye zvakanyanya kuomarara mitemo yezvakatipoteredza. Tarisa mumamiriro akadzama mavanoshanda kugadzirisa matambudziko akaomarara eindasitiri uye kubvisa basa rinorema asi rinodzokororwa.
Tricky Technical Dilemmas muDenitration
Kugadziriswa mukubuda kwenitrogen oxide (NOx) harisi basa riri nyore. Nitrogen oxide yaisagona kubviswa zvachose, zvisinei nemarasha-akapiswa, oiri-akapisa kana kunyange biomass anopisa zvidyarwa. Emissions manejimendi zvine hukama neSelective Catalytic Reduction (SCR) kana Selective Non-Catalytic Reduction (SNCR), umo mareagents anowedzerwa muflue gasi rukova kuti awedzere kuita. Zvakangodaro, kunyatsoita dosing yekutarisa munguva chaiyo inotarisana nematambudziko mazhinji kubva kumamiriro ekushanda akaomarara. Kusarurama mukuyera kunogona kukonzera kutsvedza kweammonia uye reagents marara.
Lonnmeter dhizaini uye gadzira iyo inline density mitakuitira kuenderera mberi kwekuyera kudzivirira kukanganisa kwevanhu mumuenzaniso wekare. Sampling yemunhu inotsamira zvakanyanya pa periodic cheki uye fungidziro isina kunanga. Vakadaroonline density mitainokwanisa kuona kushanduka kudiki kwe density monitoring kubatsira kunyatsogadzirisa, kuchengetedza iyo yese denitration maitiro akagadzikana uye anoshanda.
Uye zvakare, inoshandawo mukupa ma parameter anoratidza kusanganisa mhando, reagent kuenderana uye kunyange kuyerera kwehuwandu. Semienzaniso, kusapindirana kwerukova rweurea kusvika pakunyungudika mumvura kunokanganisa maitiro emakemikari. Nekutarisa slurry yakananga mupombi, inline density metres inova nechokwadi chekuti inodiwa inochengetedzwa kubva pakuchengeterwa kuenda kune jekiseni, kuderedza njodzi yekusashanda zvakanaka kana kusateedzera kwezvakatipoteredza.
Yakakurudzirwa Industrial Density Meters
Kuvandudza otomatiki muDenitration uye System Kuvimbika
Kwapera mazuva apo vashandi vezvirimwa vaifanira kuvimba nekupindira kwemaoko kuti vagadzirise jekiseni reagent. Yemazuva ano inline density metres inobatanidza zvisina musono mune advanced Distributed Control Systems (DCS) kana Programmable Logic Controllers (PLC), ichibvumira kuzere otomatiki mhinduro loop. Kana density yekuverenga ikatsauka kubva payakagadzirirwa renji, sisitimu inogadzirisa otomatiki iyo reagent kuyerera kana kudzikisa mhinduro sezvinodiwa. Iyi otomatiki haingodzikisire mutoro kune vashandisi asi zvakare inobvisa kunonoka kunoenderana nekuita sarudzo.
Zvakakosha kuenzanisa kemikari hova musanganiswa desulfurization uye denitration processing, uko lime slurry uye ammonia mhinduro dzinoshandiswa panguva imwe chete. Monitoring density yemvura mbiri idzi ndicho chinodiwa pakushanda kwakajairika kwedesulfurization uye denitration. Iyi nhanho yekubatana inobatsira kudzivirira nyaya dzakajairwa sedimentation mumapombi eraimu kana kuwandisa kweammonia, zvese zvinogona kukonzera kuvharika kana kugadzirisa zvinodhura.
Kunze kwezvo, yakadaro yakasimba inline density metres inopokana nemamiriro akashata mumagetsi emagetsi. Kune dzakakosha dhizaini kuti dzimire tembiricha yakakwira uye kumanikidzana, dzakanakira kubata makemikari anoparadza mumamiriro ezvinhu akaoma senge flue gas denitration system.
Zvishandiso zveInline Density Meters muMarasha-Anopfuta Simba Chirimwa
Kazhinji, zvidyarwa zvemagetsi emarasha zviri kunetsa nekusaita density kuyerwa uye zvine chekuita nehunyanzvi matambudziko munhevedzano, kusanganisira asi kwete kugumira pakuvharwa kwepombi, kutsvedza kweammonia uye kugona kugadzirisa. Iyo forogo inline density mita ndiyo yakanakira hungwaru chiridzwa kune ese ari maviri jekiseni reammonia uye limestone slurry system.
Migumisiro yacho yaiva shanduko. Real-time density yekutarisa yakabvumira chirimwa kuti chigadzirise reagent dosing nekurongeka kusati kwamboitika. Ammonia slip mazinga akadonhedzwa nepamusoro pe90%, nepo NOx kuderedza kushanda kwakapfuura 92%. Iyo limestone slurry, iyo yakambokonzera kuyera uye kuvharika, yakachengetwa pane yakanyanya density, ichibvisa isina kurongwa kuchengetedza uye kuderedza downtime ne20%. Kuvandudzwa uku hakuna kungounza chirimwa ichi kutevedzera magariro ezvakatipoteredza asiwo yakaderedza mitengo yekushandisa ne15%.
Nei Inline Density Meter ichikosha
Chii chinoisa inline density metres kubva kune mamwe ekutarisa mhinduro ndeyekuita kwavo kwakasiyana uye kuchinjika. Hadzina kuganhurirwa pakuramba; mashandisirwo avo anotambanukira kune chero maindasitiri maitiro anoda chaiwo magadzirirwo emvura. Muchirevo chezvidyarwa zvemagetsi, izvi zvinosanganisira desulfurization masisitimu, kuchenesa mvura yetsvina, uye mabasa ekubatanidza mafuta. Kugona kwavo kupa chaiyo-nguva, chaiyo, uye inogoneka data inoita kuti ive dombo repakona remazuva ano maitiro ekugadzirisa.
Nekushandisa zviridzwa izvi, zvidyarwa zvemagetsi zvinogona kuwana mwero wekutonga kwemaitiro izvo zvanga zvisingasvikike. Izvo zvinobatsira zvinowedzera kupfuura kutevedzera uye kushanda zvakanaka; zvinosanganisirawo kuvandudzwa kwemichina yekugara kwenguva refu, kuderedzwa kwemitengo yekugadzirisa, uye kusimudzirwa kwekusimudzira. Kune vashandisi vanokoshesa zvese zviri zviviri kuita uye basa rezvakatipoteredza, inline density metres haisi kungoisa mari - inodikanwa.
Mhedziso
Kugamuchirwa kwema inline density metres muma denitration masisitimu inoratidza kuti tekinoroji yepamusoro inogona kushandura sei maindasitiri. Nekugadzirisa zvinonetsa senge reagent kuenderana, kutsvedza kweammonia, uye kuita otomatiki, zviridzwa izvi zvinoita kuti zvidyarwa zvemagetsi zvishande nemazvo, zvakachengetedzeka, uye zvine pundutso. Rekodhi yavo yakasimbiswa mune chaiyo-yepasirese application inosimbisa kukosha kwavo sechishandiso chakakosha mukurwisa kubuda kweNOx. Kana iwe uchitsvaga kukwidziridza mashandiro ako ekubvisa, hapana nguva iri nani yekuongorora kugona kweiyo inline density kuyerwa.
