Tangi rekuchengetera ammonia yemvura
Ammonia yemvura inosanganiswa mune runyorwa rwemakemikari ane njodzi nekuda kwehunhu hwayo hunogona kutsva, kuputika, uye chepfu. Sekureva kwe "Kuzivikanwa kweManyuko Makuru Engozi eMakemikoro Ane Hazardous" (GB18218-2009), huwandu hwakakosha hwekuchengetera ammonia hunopfuura matani gumi*** hunoumba sosi huru yenjodzi. Matangi ese ekuchengetera ammonia yemvura anorongwa semhando nhatu dzemidziyo yekumanikidza. Iye zvino ongorora hunhu nenjodzi zvine njodzi panguva yekugadzira nekushanda kwetangi rekuchengetera ammonia yemvura, uye taura nezvematanho ekudzivirira uye ekukurumidza kudzivirira tsaona.
Kuongororwa kwengozi yetangi rekuchengetera ammonia yemvura panguva yekushanda
Hunhu hune njodzi hweammonia
Ammonia igesi isina ruvara uye inoonekera ine hwema hunorwadza, iyo inonyungudika nyore nyore kuita ammonia yemvura. Ammonia yakareruka kupfuura mhepo uye inonyungudika nyore nyore mumvura. Sezvo ammonia yemvura ichinyungudika nyore nyore kuita ammonia gasi, kana ammonia nemhepo zvikasanganiswa kusvika pamwero wakati, inogona kuiswa mumoto wakavhurika, huwandu hwepamusoro i15-27%, mumhepo iri muworkshop ***** *Huremu hunobvumirwa i30mg/m3. Gasi reammonia rinobuda rinogona kukonzera chepfu, kutsamwisa maziso, mucosa yemapapu, kana ganda, uye pane njodzi yekutsva nemakemikari.
Kuongorora njodzi dzekugadzira nekushanda
1. Kudzora huwandu hweAmmonia
Kana mwero wekuburitswa kweammonia wakanyanya kukurumidza, kudzora kwehuwandu hwemvura kwakaderera zvakanyanya, kana kukundikana kwekutonga kwemidziyo, nezvimwewo, gasi rekugadzira rinobuda richipinda mutangi rekuchengetera ammonia yemvura, zvichikonzera kumanikidzwa kwakanyanya mutangi rekuchengetera uye kubuda kweammonia yakawanda, izvo zvinokuvadza zvikuru. Kudzora huwandu hweammonia kwakakosha zvikuru.
2. Kugona kuchengetera zvinhu
Kugona kuchengetera kwetangi rekuchengetera ammonia yemvura kunodarika 85% yehuwandu hwetangi rekuchengetera, uye kumanikidzwa kunodarika huwandu hwe control index kana kuti kushanda kunoitwa mutangi rakapindurwa re ammonia yemvura. Kana maitiro nematanho zvisina kuteverwa zvakanyanya mumitemo yekushanda, kudonha kwemhepo zvakanyanya kuchaitika***** *tsaona.
3. Kuzadza kweammonia nemvura
Kana ammonia yemvura yazara, kuzadza zvakanyanya hakuitwe zvinoenderana nemutemo, uye kuputika kwepombi yekuzadza kunokonzera tsaona dzekubuda kwemvura uye kuchetura.
Kuongororwa kwengozi yemidziyo nenzvimbo
1. Kugadzirwa, kuongororwa, uye kugadziriswa kwematangi ekuchengetera ammonia yemvura hakusipo kana kuti hakusipo, uye zvinhu zvekuchengetedza zvakaita sema level gauges, pressure gauges, uye safety valves hazvina kunaka kana kuti zvakavanzwa, izvo zvinogona kukonzera tsaona dzekubuda kwemvura mutangi.
2. Muzhizha kana kana tembiricha yakwira, tangi rekuchengetera mvura yeammonia harina matende, mvura inotonhorera yakagadzika uye zvimwe zvinhu zvekudzivirira sezvinodiwa, izvo zvinokonzeresa kubuda kwemvura yakawanda mutangi rekuchengetera.
3. Kukuvara kana kutadza kwekudzivirira mheni uye nzvimbo dzinodzivirira kupisa kana pasi zvinogona kukonzera kuvhundutswa kwemagetsi kutangi rekuchengetera.
4. Kukundikana kwemaaramu ekugadzira, makiyi ekuvharira, rubatsiro rwekumanikidzwa kwekukurumidzira, maaramu egasi rinobvira uye rine chepfu nezvimwe zvishandiso zvinokonzeresa tsaona dzekubuda kwemhepo yakawandisa kana kukura kwetangi rekuchengetera zvinhu.
Matanho ekudzivirira tsaona
Matanho ekudzivirira mashandiro ekugadzira
1. Shandisai nzira dzekushanda zvakasimba
Tarisa mashandiro ekubvisa ammonia muzvikamu zvekugadzira, dzora huwandu hwemvura inoyerera pakati pemvura inotonhora uye inopatsanurwa neammonia, chengetedza huwandu hwemvura hwakagadzikana mukati mechikamu che1/3 kusvika 2/3, uye dzivirira huwandu hwemvura kuti husave hwakaderera zvakanyanya kana kuti hwakakwira zvakanyanya.
2. Dzora zvakasimba kumanikidzwa kwetangi rekuchengetera ammonia yemvura
Huwandu hwekuchengetera hweammonia yemvura haufanirwe kudarika 85% yehuwandu hwetangi rekuchengetera. Munguva yekugadzira yakajairika, tangi rekuchengetera ammonia yemvura rinofanira kudzorwa padanho rakaderera, kazhinji mukati me30% yehuwandu hwekuzadza hwakachengeteka, kudzivirira kuchengetwa kweammonia nekuda kwekupisa kwekunze. Kuwedzera kwekuwedzera uye kuwedzera kwekumanikidzwa kunokonzera kumanikidzwa kwakanyanya mutangi rekuchengetera.
3. Kuchenjerera pakuzadza ammonia yemvura
Vashandi vanoisa ammonia vanofanira kupasa dzidzo yehunyanzvi yekuchengetedza uye kudzidziswa vasati vatanga basa ravo. Vanofanira kunge vachiziva mashandiro, hunhu, nzira dzekushandisa, chimiro chezvishongedzo, musimboti wekushanda, hunhu hune njodzi hweammonia yemvura uye matanho ekurapa ekukurumidza.
Usati wazadza, zvitupa zvakaita sekuongororwa kwemuviri kwetangi, rezinesi rekushandisa tangi, rezinesi rekutyaira, chitupa chekuperekedza, uye mvumo yekufambisa zvinofanirwa kusimbiswa. Zvishongedzo zvekuchengetedza zvinofanirwa kunge zvakakwana uye zvine hungwaru, uye kuongororwa kunofanirwa kuve kwakakodzera; kumanikidzwa kuri mutangi usati wazadza kunofanirwa kunge kwakaderera. Pasi pe0.05 MPa; mashandiro epombi yekubatanidza ammonia anofanira kuongororwa.
Vashandi vanoisa ammonia vanofanira kunyatsotevedzera maitiro ekushandisa tangi rekuchengetera ammonia yemvura, uye vanofanira kungwarira huwandu hwekuzadza husingapfuure 85% yehuwandu hwetangi rekuchengetera pavanenge vachizadza.
Vashandi vanoisa ammonia vanofanira kupfeka mamasiki egasi nemagirovhosi ekudzivirira; nzvimbo yacho inofanira kunge yakashongedzwa nemidziyo yekudzivirira moto negasi; panguva yekuzadza, havafanirwe kubva panzvimbo yacho, uye kusimbisa kuongororwa kwesimba remotokari dzetangi, mapaipi emagetsi kuti vaone kana paine mvura inobuda, nezvimwewo, gasi remotokari dzetangi. Idzoreredzei kuhurongwa nenzira yakakodzera uye musaiburitse painoda. Kana paine mamiriro asina kujairika akadai sekubuda kwemvura, rega kuzadza nekukurumidza, uye tora matanho anoshanda ekudzivirira tsaona dzisingatarisirwi.
Kuongorora nguva dzose kwenzvimbo dzekuisa ammonia, matanho uye maitiro kunofanira kuitwa zuva nezuva, uye zvinyorwa zvekuongorora nekuzadza zvinofanira kuitwa.
