Ihe achọrọ njikwa nchekwa maka Cyanides

Cyandes na-ezo aka siri ike na ngwọta ụdị nke sodium cyanide na potassium cyanide. Nke Njikwa nchekwa of cyanides na-emetụta atụmatụ, nhazi, na nhọrọ saịtị, imewe, mmepụta, nchekwa, njem njem, Nnapụta Mberede, na njikwa nchekwa nke ụlọ ọrụ na-arụ ọrụ na mmepụta cyanide.

I. Atụmatụ, Nhazi, na Nhọrọ saịtị

Ihe owuwu ọhụrụ, ndozigharị, na ọrụ mgbasawanye nke Cyanides ekwesịrị ịhazi ya nke ọma ma debe ya n'ụzọ ezi uche dị na ya. Nhọrọ saịtị ahụ kwesịrị ịgbaso n'usoro mmepe akụ na ụba obodo na atụmatụ mmepe obodo na ime obodo ma kwesị ịrụ ya n'ime ogige ụlọ ọrụ kemịkalụ. Ihe owuwu ọhụrụ, nrụzigharị na ọrụ mgbasawanye nke cyanides, dị ka ọrụ owuwu kemịkalụ dị ize ndụ, kwesịrị ịga nyocha nchekwa dịka iwu na ụkpụrụ obodo siri dị.

II. Nhazi

Maka ihe owuwu ọhụrụ, nrụzigharị, na mgbasawanye nke cyanides, usoro njikwa akpaaka na bọtịnụ nkwụsị mberede nke na-egbo mkpa mmepụta nchekwa kwesịrị ịtọlite. Ekwesịrị ime nhazi nke oru ngo site na ngalaba imewe nwere ntozu kwekọrọ, na imewe ya kwesịrị ịgbasochi usoro nhazi na ụkpụrụ nke ọrụ nrụpụta kemịkalụ dị ize ndụ kwesịrị ịgbaso.

III. Nchekwa mmepụta

Ihe nke pipeline hydrocyanic acid mmiri kwesịrị ịbụ 304 igwe anaghị agba nchara ma ọ bụ n'elu, na ihe ndị ọzọ na-emepụta na nchekwa akụrụngwa na pipeline na kọntaktị na cyanides kwesịrị ịbụ 304 igwe anaghị agba nchara.

Ngwaọrụ mmepụta nke cyanide kwesịrị ịbụ nke nwere ọkpọkọ mkpofu mmiri iji wụpụ n'ọdụ ụgbọ mmiri na-ekpofu mmiri. Ekwesịrị iji pipeline na-anakọta mmiri mkpofu cyanide mee ihe na-egbochi corrosion na ihe ndị na-adịghị ahụ anya. Mgbe a na-ahọrọ ihe nchara carbon, ekwesịrị ịme ọgwụgwọ mgbochi corrosion na mgbochi anya. Ekwesịrị iji ọgwụ mgbochi corrosion na mgbochi seepage mesoo ala ihe nke ebe a na-emepụta ihe. Ekwesịrị iji ihe mgbochi corrosion na mgbochi seepage gwọọ oghere ọkpọkọ dị n'okpuru ala site na iji kọmpụta siri ike.

Ekwesịrị ịtọlite ​​​​ngwaọrụ ịgbasa mmanya alkali maka igwe ikuku ikuku mberede nke ngwaọrụ mmepụta cyanide mmiri. Ike ọkọnọ nke alkali mmanya ịgba mgbapụta kwesịrị ka a kwadebere ya na ndabere ike ọkọnọ nweta ngwa ngwa ịmafe.

E kwesịghị iji usoro ikuku ventilashị na-ekesa n'ebe ọrụ. Ebe dị elu nke ikpo ọkụ nke ọdụ gas na ngwaọrụ iyuzucha mpaghara ekwesịghị ịdị ala karịa mita 25.

Mgbe ị na-arụ ọrụ n'ebe dị ize ndụ ebe a na-emepụta gas na-egbu egbu na nke na-emerụ ahụ, ekwesịrị inwe ihe karịrị ndị ọrụ abụọ. Otu onye na-arụ ọrụ ebe onye nke ọzọ na-enyocha, na ndị ọrụ kwesịrị ka a na-enyocha ya n'oge usoro ahụ. Ihe nrụpụta na ebe nchekwa ọ bụla kwesịrị ịnwe ihe karịrị abụọ akụrụngwa iku ume oxygen nwere onwe ya yana ngwa iku ume ogologo tube.

IV. Nchekwa Nchekwa

Ụlọ nkwakọba ihe maka cyanide siri ike kwesịrị ịbụ ụlọ nkwakọba ihe raara onwe ya nye, echekwara na ebe ikuku na-ekpo ọkụ na nke akọrọ. A ga-etinyerịrị usoro “paịs ise” nke nnata na izipu mmadụ abụọ, ndekọ ego mmadụ abụọ, mkpọchi okpukpu abụọ, njem mmadụ abụọ, na iji mmadụ abụọ eme ihe nke ọma, wee guzobe usoro mkpu na nlekota nke awa 24.

Ekwesịrị ịme tankị nchekwa cyanide mmiri mmiri nke ihe na-eguzogide alkali. Cyanide mmiri mmiri kwesịrị ịdị jụụ nke ọma tupu ya abanye na nchekwa nchekwa, na okpomọkụ nke nchekwa nchekwa kwesịrị idobe n'okpuru 25 Celsius C iji gbochie polymerization na ire ere nke cyanide mmiri. A ghaghị ịkwado tankị nchekwa ahụ na ọkwa ọkwa mmiri dị elu na ngwaọrụ ntinye aka na-akpaghị aka maka igbuchapụ nri mgbe ọkwa mmiri dị oke elu. Ekwesịrị ịtọ akwa akwa na ebe nchekwa mmiri mmiri, a ga-edozi ala ahụ na ihe mgbochi anya, na ebe a na-ebufe ma ọ bụ ọdọ mmiri mmiri kwesịrị ịkwado.

V. Nchekwa ụgbọ njem

Ekwesịrị ịrụ ọrụ nbudata na nbudata nke cyanides n'okpuru iwu saịtị nke ndị ọrụ nchịkwa na nbudata. Tupu na mgbe ebutu na ibutu ụgbọ ala, ekwesịrị ịsacha ya nke ọma. Ndị ọrụ njikwa nbudata na nbudata kwesịrị iji nlezianya lelee ma nkọwapụta na ọnụọgụ cyanide kwekọrọ na akwụkwọ mbupu; onye na-edu ya kwesịrị ibu ụzọ buru ngwongwo ndị dị ize ndụ Nchedo njem kaadị na nchekwa teknụzụ nkọwa nke cyanides. Maka ụgbọ ala tankị na-ebu cyanide mmiri mmiri, a ga-enyocha tankị ụgbọ ala ma ruo eru na n'ime oge kwesịrị ekwesị.

Ekwesịrị iburu cyanide mmiri mmiri site na pipeline n'ime ụlọ ọrụ mmepụta ihe. Ihe nke pipeline njem kwesịrị ịbụ igwe anaghị agba nchara na-adịghị ala karịa 304. Njikọ njikọ nwere ike ịbụ flanges, na akụkụ ndị ọzọ kwesịrị welded. Agbalịrị 100% nrụrụ welds ahụ. Okpomọkụ ụgbọ njem ekwesịghị ịfe 25 Celsius, na jaket dị n'èzí nke pipeline kwesịrị inye ihe mkpuchi oyi. Pipeline ụgbọ njem kwesịrị ịnakwere usoro mmịpụta na-ekesa. Ekwesịrị itinye ngwaọrụ njikọ nke mkpu gas na-egbu egbu na mmechi akpaaka nke valvụ a na-ebipụ na flanges nke pipeline njem ma ọ bụ n'ebe enwere ike ịgbapụta. Ekwesịrị ịkwado pipeline nke ụgbọ njem na ngwaọrụ na-afụ eriri, nke kachasị mma nkedo nkedo nke na-ekpo ọkụ. Mgbe emechara njem ahụ, a ga-eji gas inert mee ka mmiri ahụ laghachi azụ n'ime tankị nchekwa ahụ, a ga-etinyekwa ngwaọrụ mgbake mmiri na-ekpofu n'ọdụ ụgbọ mmiri mmiri.

VI. Nnapụta ihe mberede

Ụlọ ọrụ mmepụta nke Cyanide kwesịrị ịmalite ma melite òtù mberede na ndị ọrụ mberede oge (nke oge), hazie ngwá ọrụ mberede na ihe ndị kwesịrị ekwesị maka iguzogide ihe ize ndụ nke ụlọ ọrụ ahụ, kwadebe atụmatụ nzaghachi mberede, ma na-eme ihe mberede mberede mgbe niile. Nleba anya nke cyanide na saịtị kwesịrị ịbụ ihe na-erughị 1mg/m³, na ekwesịrị idobe bọọdụ ọkwa.

Enwere ike iji ntụ ntụ na ájá mee ka ọkụ kwụsị. A machibidoro carbon dioxide na ihe mgbanyụ ọkụ acid-base maka imenyụ ọkụ. Ndị ọrụ mgbanyụ ọkụ ga-eyiri ihe mkpuchi gas na uwe mkpuchi ọkụ na nke na-egbu egbu n'ahụ zuru oke ma lụso ọkụ na-ebuli elu ọgụ. Ekwesịrị ịrụ olulu iji kpokọta nsị na-egbochi ọkụ maka ọgwụgwọ, e kwesịghịkwa ịwụpụ ya na mberede.

Mgbe enwere mgbawa, gbalịa ka ebipụ isi iyi ahụ dị ka o kwere mee ka ọdụ ụgbọ mmiri ahụ ghara ịbanye na mmiri. Hapụ n'ebe a na-agbapụta mmiri, chụpụ ndị ọrụ na-adịghị mkpa, ma kpachie mpaghara ịdọ aka ná ntị. Lezienụ anya ka ị nọrọ elu. Amachibidoro ka ihe ndị na-agbapụta agbapụta banye n'ime oghere amachibidoro dịka ozu mmiri, ọkpọkọ dị n'okpuru ala, ma ọ bụ ọwa mmiri na-agbapụta.
