IiMfuno zoLawulo loKhuseleko kwiiCyanides

Ii- C yanides zibhekisa kwiindlela eziqinileyo nezinyibilikayo zeSodium cyanide kunye ne-potassium cyanide. Ulawulo loKhuseleko lwee -cyanides lusebenza ekucwangcisweni, ekubekweni, nasekukhethweni kwendawo, uyilo, imveliso, indawo yokugcina, ukuthuthwa, ukuhlangulwa ngexesha likaxakeka , kunye nolawulo lokhuseleko lwamashishini abandakanyeka kwimveliso ye-cyanide.

I. UCwangciso, uYilo, kunye noKhetho lweSiza

Iiprojekthi ezintsha zokwakha, ukuhlaziya, kunye nokwandisa iiCyanides kufuneka zicwangciswe ngokupheleleyo kwaye zicwangciswe ngokwengqiqo. Ukukhethwa kwendawo kufuneka kuhambelane nophuhliso lwezoqoqosho lwengingqi kunye nezicwangciso zophuhliso lwedolophu kunye nelasemaphandleni kwaye kufuneka kwakhiwe ngaphakathi kwepaki yemizi-mveliso yeekhemikhali. Iiprojekthi ezintsha zokwakha, ukuhlaziya, kunye nokwandisa iiCyanides, njengeeprojekthi zokwakha iikhemikhali eziyingozi, kufuneka zihlolwe ngokhuseleko ngokuhambelana nemithetho nemigaqo yesizwe efanelekileyo.

II. Yila

Ukwakhiwa okutsha, ukulungiswa, kunye nokwandisa iiprojekthi ze-cyanides, inkqubo yokulawula ngokuzenzekelayo kunye neqhosha lokumisa likaxakeka elihlangabezana neemfuno zokuvelisa ukhuseleko kufuneka zimiselwe. Uyilo lweprojekthi kufuneka lwenziwe yiyunithi yoyilo kunye neziqinisekiso ezihambelanayo, kwaye uyilo kufuneka lulandele ngokuthe ngqo inkcazo yoyilo kunye nemigangatho ekufuneka iiprojekthi zokwakhiwa kweekhemikhali ezinobungozi zithobele.

III. Ukhuseleko lweMveliso

Izinto eziphathekayo zombhobho we-hydrocyanic acid elulwelo kufuneka zibe yi-304 yensimbi engenasici okanye ngaphezulu, kunye nezixhobo zezinye izixhobo zokuvelisa kunye nokugcinwa kunye nemibhobho edibana ngokuthe ngqo kunye ne-cyanides kufuneka ibe yi-304 yensimbi engenasici.

Isixhobo sokuvelisa i-cyanide kufuneka sixhotyiswe ngombhobho wokuqokelelwa kwamanzi amdaka ukuze ukhuphele kwisikhululo sokucoca ugutyulo. Umbhobho wokuqokelelwa kwamanzi amdaka e-cyanide kufuneka wenziwe ngezinto ezichasayo ukubola kunye nezixhobo ezichasayo. Xa izinto zensimbi zekhabhoni zikhethiweyo, i-anti-corrosion kunye ne-anti-seepage unyango kufuneka iqhutywe. Umgangatho wekhonkrithi wendawo yokuvelisa kufuneka uphathwe ngamanyathelo okuchasa ukubola kunye ne-anti-seepage. Umngxuma wemibhobho ongaphantsi komhlaba kufuneka unyangwe ngamanyathelo okuthintela ukubola kunye nokunqanda ukuqhekeka kusetyenziswa ikhonkrithi eyomeleziweyo.

Isixhobo sokufunxa isitshizi sotywala bealkali kufuneka simiselwe itshimini yokukhupha umoya kaxakeka yesixhobo solwelo sokuvelisa icyanide. Unikezelo lwamandla lwempompo yokutshiza yotywala bealkali kufuneka luxhotyiswe ngonikezelo lwamandla olugciniweyo ukuphumeza ukutshintshwa ngokukhawuleza.

Inkqubo yokungenisa umoya ejikelezayo ayifanele isetyenziswe kwindawo yokusebenza. Ukuphakama kweemfumba zokukhutshwa kwegesi yomsila kunye nezixhobo zokukhupha zendawo akufanele zibe ngaphantsi kweemitha ezingama-25.

Xa usebenza kwiindawo ezinobungozi apho kuveliswa iigesi ezinobuthi kunye neziyingozi, kufuneka kubekho abasebenzi abangaphezu kwesibini. Umntu omnye usebenza ngelixa omnye ebeka iliso, kwaye abasebenzi kufuneka babekwe esweni kuyo yonke le nkqubo. Isithuba ngasinye semveliso kunye nokugcinwa kufuneka sixhotyiswe ngaphezu kwezixhobo ezimbini zokuphefumla ioksijini ezizimeleyo kunye nezixhobo zokuphefumla ezinde.

IV. Ukhuseleko loGcino

Indawo yokugcina iicyanides ezomeleleyo kufuneka ibe yindawo yokugcina impahla, egcinwe kwindawo engenamoya neyomileyo. Inkqubo "yezibini ezihlanu" zokufumana kunye nokuthunyelwa komntu kabini, ukubalwa kwabantu kabini, ukutshixa kabini, ukuthuthwa kwabantu ababini, kunye nokusetyenziswa komntu ophindwe kabini kufuneka kuphunyezwe ngokungqongqo, kwaye i-alarm yeeyure ezingama-24 kunye nenkqubo yokubeka iliso kufuneka imiselwe.

Itanki yokugcina i-cyanide yolwelo kufuneka yenziwe ngezinto ezikwazi ukumelana ne-alkali. Icyanide engamanzi kufuneka ipholiswe ngokupheleleyo phambi kokuba ingene kwitanki yokugcina, kwaye ubushushu betanki yokugcina kufuneka bugcinwe ngaphantsi kwe 25°C ukunqanda upholima kunye nokubola kwecyanide engamanzi. Itanki yokugcina kufuneka ixhotyiswe nge-alam yomgangatho ophezulu wolwelo kunye nesixhobo esizitshixayo esizenzekelayo sokunqumla i-feed xa umgangatho wolwelo uphezulu ngokugqithisileyo. I-weir kufuneka ibekwe kwindawo yokugcina amanzi, umhlaba kufuneka uphathwe ngamanyathelo achasene ne-seepage, kwaye itanki yokudlulisa okanye i-pool yokugcina amanzi kufuneka ixhotyiswe.

V. Ukhuseleko lwezoThutho

Imisebenzi yokulayisha nokukhupha i-cyanides kufuneka yenziwe phantsi komyalelo wabasebenzi bolawulo lokulayisha nokukhupha imithwalo kwindawo leyo. Ngaphambi nasemva kokulayisha nokukhupha imithwalo kwisithuthi sothutho, kufuneka icocwe kakuhle. Abasebenzi bolawulo lokulayisha nokukhupha imithwalo kufuneka bajonge ngononophelo ukuba iinkcukacha kunye nobungakanani be-cyanides ziyahambelana namaxwebhu okuthumela; umntu ophetheyo kufuneka aphathe ikhadi loKhuseleko lweempahla eziyingozi zendlela kunye nenkcazo yobuchwephesha bokhuseleko lwe-cyanides. Kwizithuthi zetanki ezithutha i-cyanides engamanzi, itanki yesithuthi kufuneka ihlolwe kwaye iqinisekiswe kwaye ngaphakathi kwexesha elivumelekileyo.

Iicyanides ezilulwelo kufuneka zithuthwe ngombhobho ngaphakathi kumzi-mveliso. Izinto eziphathekayo zombhobho wokuthutha kufuneka zibe yintsimbi engenasici engekho ngaphantsi kwe-304. Izibuko zokudibanisa zingaba yi-flanges, kwaye ezinye iindawo kufuneka zifakwe kwi-welded. I-welds kufuneka ihlolwe i-100% ye-flaw-detection. Iqondo lokushisa lokuthutha akufanele lidlule i-25 ° C, kunye nejacket yangaphandle yombhobho kufuneka inikezelwe ngamanyathelo okubamba okubandayo. Umbhobho wokuthutha kufuneka usebenzise indlela yokutsalwa okujikelezayo. Isixhobo sonxibelelaniso se-alam yerhasi eyityhefu kunye nokuvalwa ngokuzenzekelayo kwevalve yokuvala kufuneka kufakwe kwiiflange zombhobho wothutho okanye kwiindawo apho ukuvuza kunokwenzeka khona. Umbhobho wothutho kufuneka uxhotyiswe ngesixhobo sokuvuthela ngomgca, ekukhetheke ukuba ube yijoyini yokuvuthela engagungqiyo. Emva kokuba uthutho lugqityiwe, irhasi ye-inert kufuneka isetyenziswe ukuvuthela ulwelo kwakhona kwitanki yokugcina, kunye nesixhobo sokubuyisela ulwelo lwenkunkuma kufuneka sifakwe kwindawo yokukhupha ulwelo.

VI. Uhlangulo oluNgxamisekileyo

Amashishini okuvelisa i-Cyanide kufuneka aseke kwaye aphucule imibutho engxamisekileyo kunye namaqela angxamisekileyo asisigxina (ixesha lexeshana), aqulunqe izixhobo ezingxamisekileyo kunye nezinto ezilungele ukumelana neengozi zeshishini, alungiselele izicwangciso zokusabela kwimeko yongxamiseko, kwaye aqhube ii-drills rhoqo ezingxamisekileyo. Ugxininiso lwecyanide olubekwe esweni kwindawo kufuneka lube ngaphantsi kwe-1mg/m³, kwaye kufuneka kumiselwe ibhodi yezaziso.

Umgubo owomileyo kunye nesanti zingasetyenziselwa ukucima umlilo. Ikhabhon diokside kunye nezitshizi zokucima umlilo ezineasidi azivumelekanga ukuba zicime umlilo. Abacimi-mlilo kufuneka banxibe iimaski zerhasi kunye nempahla egcweleyo engatshiyo kunye neyokulwa netyhefu kwaye balwe nomoya ovuthuzayo. Iidikhi kufuneka zakhiwe ukuze kuqokelelwe ilindle lokulwa nomlilo ukuze linyangwe, kwaye akufuneki likhutshwe ngokungalindelekanga.

Xa kukho ukuvuza, zama ukusika umthombo wokuvuza kangangoko unakho ukukhusela izibuko lokuvuza ekudibaneni namanzi. Hlala kude nesiza sokuvuza, khupha abasebenzi abangabalulekanga, kwaye ucande umda kwindawo yesilumkiso. Nika ingqalelo ukuhlala ungeva. Akuvumelekanga ukuba izinto ezivuzayo zihambe ziye kwiindawo ezithintelweyo ezifana namanzi, imibhobho engaphantsi komhlaba, okanye imisele yokukhupha izandyondyo.
