Ivalve yebhabhathane yombanekwizityalo zamandla ezishushu kunye nezinye iiprojekthi ezinkulu ekusetyenzisweni kokwabelana ngetyala

Ivalve yebhabhathane yombane luhlobo lwezixhobo zevalve yokulawula ulwelo, esetyenziswa kakhulu kwipetroleum, imichiza, amayeza, amandla kunye namanye amashishini. Eli phepha liza kuthatha izityalo zamandla e-thermal njengomzekelo wokwabelana ngeemeko zesicelo kunye nemiphumo yokusetyenziswa kweevalvu zebhabhathane zombane kwiiprojekthi ezinkulu ezifana nezityalo zamandla okushisa.

Okokuqala, ukusetyenziswa kwevalve yebhabhathane yombane kwizityalo zamandla ezishushu

1. Ukuchithwa kwerhasi yomkhuhlane

Isibaso esiqhele ukusetyenziswa kwimizi-mveliso yamandla obushushu, njengamalahle, siya kuvelisa iigesi ezininzi eziyingozi njengesulphur dioxide xa zitshisiwe. Ngoko ke, kuyimfuneko ukunciphisa ukungcoliseka kwendalo nge-flue gas desulfurization. Kule nkqubo, i-valve yebhabhathane yombane, njengesixhobo sevalve eqhelekileyo, isetyenziselwa ukulawula ukuhamba kunye nokuxinana kweekhemikhali kwi-reactor, kunye nokulawula ukukhutshwa kwe-sulfure dioxide ekuphumeni ngelixa uqinisekisa ukuxinwa kwe-reactant kwi-reactor. iyunithi yokusabela iyafana. Ukusebenzisa ivalve yebhabhathane yombane yolawulo oluchanekileyo, ukuphumeza ukuhamba kakuhle kokungenisa elizweni kunye nolwelo lokuthumela ngaphandle, ukunciphisa ungcoliseko lokusingqongileyo.

2. I-Denitrification yegesi yombane

Ukukhutshwa kwerhasi yomkhuhlane ngumlinganiselo obalulekileyo wokukhuselwa kokusingqongileyo kwizityalo zamandla obushushu. Kwirhasi ye-flue egqityiweyo, ukukhutshwa kwe-nitrogen dioxide, i-nitrous oxide kunye nezinye iigesi eziyingozi zehle kakhulu. Kwinkqubo ye-flue gas denitrification, i-valve ye-butterfly yombane isetyenziswa ngokubanzi kulawulo lokuhamba kweekhemikhali ezahlukeneyo, ezifana ne-sodium hydroxide, i-nitrite ye-sodium, i-denitrification catalyst, njl., Ukuqinisekisa umphumo we-chemical reaction kunye nokunciphisa ukungcoliswa kwendalo. .

3. Ulawulo lwemibhobho yobushushu

Umbhobho wobushushu kwiplanti yamandla obushushu ngumbhobho obalulekileyo wokuhambisa amandla obushushu, kwaye ukuhamba kwawo kufuneka kulawulwe sisixhobo sevalvu. Ukusetyenziswa kwevalve yebhabhathane yombane ukulawula umbhobho wobushushu kuneenzuzo ezithile kulawulo oluchanekileyo lokuhamba, ubushushu, uxinzelelo kunye nezinye iiparamitha, ezinokubonelela ngesiqinisekiso semisebenzi yokuvelisa kwifektri kunye nokuphucula ukusebenza kakuhle kunye nokusebenza kakuhle kwemveliso.

Okwesibini, umphumo wokusetyenziswa kwevalve yebhabhathane yombane kwizityalo zamandla ezishushu

1. Iinzuzo zokusingqongileyo

Ngokuqwalaselwa okuqhubekayo koluntu ekukhuselweni kokusingqongileyo, izityalo zamandla ashushu kufuneka zinciphise ukungcoliseka kwendalo kunye nempilo yabantu ngeendlela ezahlukeneyo. Kwi-flue gas desulfurization, i-flue gas denitrification kunye nezinye iinkqubo, ulawulo oluchanekileyo kunye nokulawulwa kokuhamba kwevalve yebhabhathane yombane kunokunciphisa ukukhutshwa kweekhemikhali kunye neegesi ezinobungozi, kwaye ufezekise injongo yokukhusela okuluhlaza kunye nokusingqongileyo.

2. Ukufika ngexesha

Umzi-mveliso wamandla obushushu sisiseko samandla ombane eluntwini, esidlala indima ebalulekileyo ekuzinziseni isicwangciso sesizwe samandla nokuqinisekisa ukhuseleko lwamandla. Ukusetyenziswa kwezixhobo ezisebenzayo nezichanekileyo zokulawula ulwelo ezifana neevalvu zebhabhathane zombane zinokuphendula ngcono kwinkqubo yolawulo kunye neemfuno zohlengahlengiso kuzo zonke iinkalo zeplanti yamandla obushushu, ukubonelela ngengxelo ngexesha nangexesha elichanekileyo, ngaloo ndlela inceda ekuphuculeni ukusebenza kakuhle kwemveliso kunye nokuqinisekisa ukuzinza kwemveliso. unikezelo lwamandla.

Inyathelo lesi-3: Ukhuseleko

Zonke izibonelelo eziphambili kunye ne-accessory ekusebenzeni kweplanti yamandla e-thermal kufuneka iqinisekise ukusebenza kwayo okukhuselekileyo kunye nokuzinza. Ivalve yebhabhathane yombane iqinisekisa ukhuseleko lomsebenzi weplanti yamandla ashushu ngobuchwepheshe obuphezulu kunye nezixhobo. Ivalve yebhabhathane yombane iqinisekisa ulawulo oluchanekileyo lokuhamba, kwaye ukuzinza kwayo kunye nokhuseleko nazo ziqinisekisiwe kakuhle.

4. Iinzuzo zoqoqosho

I-valve ye-butterfly yombane ineempawu zolawulo oluchanekileyo kunye nokuphendula ngokukhawuleza, okunokuthi kugqitywe ngokufanelekileyo ukulawula ukuhamba kunye nokulawulwa kwemveliso kwinkqubo yokuvelisa. Oku akuncedi nje ukuphucula ukusebenza kakuhle kunye nokusebenza kakuhle kwemveliso, kodwa kuzisa iinzuzo zoqoqosho malunga nokunciphisa ukusetyenziswa kwamandla, ukunciphisa inani lee-agent zemichiza, kunye nokwandisa ubomi bezixhobo.

Ngamafutshane, ukusetyenziswa kweevalvu zebhabhathane zombane kwiiprojekthi ezinkulu ezifana nezityalo zamandla obushushu ziye zamkelwa ngokubanzi ngeenzuzo kunye neenzuzo. Ngohlaziyo oluqhubekayo lwetekhnoloji yeplanti yamandla obushushu kunye nokwanda kolwazi lokukhuselwa kwendalo, ivalve yebhabhathane yombane iya kuqhubeka idlala indima ebalulekileyo kulawulo lokusingqongileyo kwifektri, ukulawulwa kwemveliso, kunye nokunciphisa ukusetyenziswa.
