Ihe achọrọ njikwa nchekwa maka Cyanides

C yanides na-ezo aka n'ụdị siri ike na nke ngwọta nke Sodium cyanide na potassium cyanide. Njikwa Nchekwa nke cyanides metụtara nhazi, nhazi, na nhọrọ ebe, imewe, mmepụta, nchekwa, njem, Nzọpụta Mberede , na njikwa nchekwa nke ụlọ ọrụ ndị na-eme mmepụta cyanide.

I. Atụmatụ, Nhazi, na Nhọrọ saịtị

A ga-eme atụmatụ maka ọrụ owuwu ọhụrụ, nrụzigharị, na mgbasawanye nke Cyanide nke ọma ma hazie ya nke ọma. Nhọrọ ebe a ga-esi rụọ kwesịrị ịgbaso mmepe akụ na ụba mpaghara na atụmatụ mmepe obodo na ime obodo, a ga-ewukwa ya n'ime ogige mmepụta kemịkalụ. Ọrụ owuwu ọhụrụ, nrụzigharị, na mgbasawanye nke cyanides, dị ka ọrụ owuwu kemịkalụ dị ize ndụ, kwesịrị ịga nyocha nchekwa dịka iwu na ụkpụrụ mba si 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

A ga-arụ ọrụ ibu na ibupụ cyanides n'okpuru iwu nke ndị ọrụ njikwa ibu na ibupụ cyanides n'ebe ahụ. Tupu na mgbe ebu na ibupụ ygbọala ahụ gasịrị, a ga-ehicha ya nke ọma. Ndị ọrụ njikwa ibu na ibupụ cyanides kwesịrị iji nlezianya lelee ma nkọwapụta na ọnụọgụ nke cyanides hà kwekọrọ na akwụkwọ mbupu; onye na-eso ygbọala kwesịrị ibu ngwaahịa dị ize ndụ n'okporo ụzọ kaadị nchekwa njem na nkọwapụta teknụzụ nchekwa nke cyanides. Maka ụgbọ ala tankị na-ebu cyanides mmiri mmiri, a ga-enyocha ma nweta asambodo na tank ụgbọ ala ahụ 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.
