Liquid ammonia kuchengetedza tangi
Liquid ammonia inosanganisirwa murondedzero yemakemikari ane njodzi nekuda kwekupisa kwayo, kuputika, uye chepfu.Zvinoenderana ne "Identification of Major Hazardous Sources of Hazardous Chemicals" (GB18218-2009), iyo yakakosha ammonia yekuchengetedza vhoriyamu inodarika 10 matani *** inoita sosi huru yenjodzi.Ese emvura ammonia ekuchengetedza matangi anoiswa semhando nhatu dzekumanikidza midziyo.Iye zvino ongorora maitiro ane ngozi uye njodzi panguva yekugadzira uye kushanda kweiyo liquid ammonia yekuchengetedza tangi, uye kurudzira mamwe ekudzivirira uye ekukurumidzira matanho ekudzivirira tsaona.
Njodzi kuongororwa kwemvura ammonia yekuchengetedza tangi panguva yekushanda
Izvo zvine ngozi zvimiro zveammonia
Ammonia igasi risina ruvara uye rakajeka rine kunhuhwirira kwakashata, iyo inonyungudutswa nyore mumvura ammonia.Amoniya yakareruka kupfuura mweya uye inonyungudika zviri nyore mumvura.Sezvo mvura yeammonia iri nyore kushanduka kuita gasi reammonia, kana ammonia nemhepo zvasanganiswa kune imwe chiyero, inogona kuratidzwa nemoto wakavhurika, huwandu hwepamusoro hunosvika 15-27%, mumhepo yakadzika yemusangano ***** *Iyo inotenderwa kusungirirwa ndeye 30mg/m3.Kubuda kweammonia gasi kunogona kukonzera chepfu, kushatirwa kwemaziso, lung mucosa, kana ganda, uye pane njodzi yekupisa kwekemikari.
Kuongororwa kwengozi yekugadzirwa uye maitiro ekushanda
1. Ammonia level control
Kana iyo ammonia yekuburitsa chiyero ichimhanya zvakanyanya, iyo yemvura level mashandiro ekudzora yakadzikira, kana kumwe kutadza kutonga kwechiridzwa, nezvimwewo, iyo yekugadzira yakakwirira-kudzvanywa gasi inopukunyuka ichipinda mumvura yeammonia yekuchengetera tangi, zvichikonzera kudzvinyirira mutangi rekuchengetedza uye. huwandu hwakawanda hwekudonha kweammonia, izvo zvinokuvadza zvakanyanya.Kudzora kweammonia level kwakakosha zvikuru.
2. Kuchengetedza kukwanisa
Iyo yekuchengetera tangi yemvura ammonia yekuchengetedza tank inodarika 85% yevhoriyamu yetangi rekuchengetedza, uye kudzvanywa kunodarika iyo control index renji kana kuvhiya kunoitwa mune yemvura ammonia inverted tank.Kana maitiro nematanho asina kunyatsotevedzwa mumirau yekushanda, overpressure leakage ichaitika ****** *tsaona.
3. Liquid ammonia kuzadza
Kana ammonia yemvura yazadzwa, kuwandisa hakuitwe zvinoenderana nemirairo, uye kuputika kwepombi yekuzadza kunokonzeresa tsaona dzekuvuza uye chepfu.
Kuongororwa kwengozi yemidziyo uye zvivakwa
1. Magadzirirwo, kuongorora, uye kuchengetedzwa kwematangi ekuchengetera emvura ammonia anoshaikwa kana kuti kwete, uye zvinhu zvekuchengetedza zvakaita segeji dzemazinga, geji dzekumanikidza, uye mavharuvhu ekuchengetedza hazvina kukwana kana kuvanzwa, izvo zvinogona kukonzera tsaona yekudonha kwetangi.
2. Muzhizha kana kana tembiricha yakakwira, tangi yemvura yekuchengetera ammonia haina kugadzirwa neawnings, yakagadzika inotonhorera yekupfapfaidza mvura uye zvimwe zvigadziriso zvekudzivirira sezvinodiwa, izvo zvinokonzeresa kudzvinyirirwa kuvuza kwetangi rekuchengetedza.
3. Kukuvadza kana kukundikana kwekudzivirira kwemheni uye anti-static zvivako kana pasi zvinogona kukonzera kushamiswa kwemagetsi kune tangi yekuchengetedza.
4. Kutadza kwekugadzira maaramu, kuvharika, kudzoreredzwa kwekumanikidzwa kwechimbichimbi, zvinopisa uye zvine muchetura gasi maaramu uye zvimwe zvishandiso zvinokonzeresa tsaona yekudonha kwemhepo kana kuwedzera kwetangi rekuchengetedza.
Matanho ekudzivirira njodzi
Matanho ekudzivirira ekugadzira maitiro ekushanda
1. Nyatsoshandisa maitiro ekushanda
Teerera kune kushanda kwekuburitsa ammonia muzvigadzirwa zvekugadzira, dzora mwero wemvura wemuchinjiko unotonhora uye ammonia kupatsanurwa, chengetedza mwero wemvura wakagadzikana mukati meiyo 1/3 kusvika 2/3, uye kudzivirira iyo mvura nhanho kuti isanyanya kuderera kana. zvakanyanyisa.
2. Nyatsodzora kudzvinyirira kwemvura ammonia yekuchengetedza tangi
Kuchengetera vhoriyamu yemvura ammonia haifanire kudarika 85% yevhoriyamu yekuchengetera tangi.Munguva yekugadzirwa kwakajairwa, iyo mvura ammonia yekuchengetedza tangi inofanirwa kudzorwa padanho rakaderera, kazhinji mukati me30% yevhoriyamu yakachengeteka yekuzadza, kudzivirira kuchengetedza ammonia nekuda kwekudziya kweambient.Kuwedzera kuwedzera uye kuwedzera kwekumanikidza kunokonzeresa kuwandisa mutangi rekuchengetedza.
3. Chengetedzo yekuzadza ammonia yemvura
Vashandi vanoisa ammonia vanofanirwa kupasa hunyanzvi hwekuchengetedza dzidzo uye kudzidziswa vasati vatora zvinzvimbo zvavo.Vanofanirwa kujairana nekuita, maitiro, nzira dzekushanda, dhizaini dhizaini, misimboti yekushanda, hunhu hune njodzi hwemvura ammonia uye matanho ekurapa kwekukurumidzira.
Usati wazadza, huchokwadi hwezvitupa zvakaita setangi rekuongorora muviri, rezinesi rekushandisa tanker, rezinesi rekutyaira, chitupa chekuperekedza, uye mvumo yekufambisa zvinofanirwa kusimbiswa.Zvishandiso zvekuchengetedza zvinofanirwa kunge zvakakwana uye zvine hanya, uye ongororo yacho inofanirwa kuve inokodzera;kudzvinyirirwa mutangi risati razadza kunofanira kunge kwakaderera.isingasviki 0.05 MPa;kushanda kwepombi yekubatanidza ammonia kunofanira kuongororwa.
Vashandi vanoisa ammonia vanofanirwa kunyatso kutevedzera maitiro eiyo liquid ammonia yekuchengetedza tangi, uye teerera kune yekuzadza vhoriyamu isingapfuuri 85% yevhoriyamu yekuchengetera tangi kana uchizadza.
Vashandi vanoisa ammonia vanofanira kupfeka masiki egasi uye magurovhosi ekudzivirira;nzvimbo yacho inofanira kunge yakashongedzerwa nemoto-yekudzivirira uye gasi midziyo yekudzivirira;panguva yekuzadza, havafanirwe kusiya saiti, uye kusimbisa kuongororwa kwekumanikidza kwetangi rori, pombi flanges yekuvuza, nezvimwewo, tank rori gasi Idzorere kune iyo sisitimu zvinoenderana uye kwete kuiburitsa pamadiro.Kana paine chero mamiriro ezvinhu asina kujairika akadai sekudonha, rega kuzadza nekukurumidza, uye tora matanho anoshanda ekudzivirira tsaona dzisingatarisirwe.
Kuongororwa kwechinyakare kwenzvimbo dzekuisa ammonia, zviyero uye maitiro zvichaitwa zuva nezuva, uye kuongorora uye kuzadza zvinyorwa zvichaitwa.
