Iintlobo zokucima umlilo

Yinto eyaziwayo ukuba sokucima umlilo yeyona ndlela ibalulekileyo nesebenza ekulweni nomlilo. Xa usebenzisa yona ukuba imizuzu embalwa ukunqanda umlilo. Ngoko ke, umbutho nganye kwindawo esemboniselweni zifikeleleke kufuneka zibekwe yeyona ndlela iphambili ukhuseleko emlilweni. Iindidi zokucima umlilo kuxhomekeke izinto eziqulathwe kuzo. Basenokuba ngohlobo amanzi, alephuze amagwebu, umgubo, icarbon dioxide, nitrogen kunye nezinye iigesi egalelwe amachiza. Xa ukuqaliswa sokucima umlilo umlomo wayo bokwenziwa kwento leyo ungacimi umlilo. wokunciphisa Content kwenzeka phantsi koxinzelelo oluphezulu kakhulu.

Iindidi zokucima kusetyenziswa ngexesha imililo, kuxhomekeka kuhlobo komlilo. Kukho ezine eziqhelekileyo iiklasi umlilo, eyabelwe neesimboli ahambelanayo. Iklasi yokuqala (A) - sokutshisa into eqinileyo, nto leyo sikhatshwa yokubola. Ezi ziquka iinkuni, iphepha, kunye namalaphu. Class B iquka self ukutshiswa kwezinto engamanzi musa ukuluhlakaza emanzini (benzene, petroleum kaEtere), kwakunye amacandelo ezinyibilikayo (utywala, glycerol). Le uDidi C libhekisa ucinezelo kwezinto sukube (igesi yendalo, propane). Class fire D - iintsimbi evuthayo kunye aluminiyamu yayo (hydrides yesinyithi, iikhompawundi organometallic). Class E libhekisela umlilo zombane.

Phezu ucinezelo bolwelo, izinto eziqinileyo kwakunye sukube kusetyenziswa iintlobo enjalo zokucima umlilo, njengoko ngumgubo. Umgubo jet ukuba ekutyibilikeni kumacala ahlukeneyo ukuze kukugalela amadangatye.

Xa oku kwenziwe, kufuneka ekugqibeleni kukugubungela maleko eyahlukileyo nomgubo nakujoliso olutsha ucinezelo. Ngethuba le nkqubo, kufuneka ukuba angenise iinxalenye ezaphukileyo. Xa ukutshiswa kwezinto ulwelo (class B lomlilo), umsinga kufuneka ibhekiswe ikakhulu ekupheleni proximal. Feed umgubo kufuneka wenziwe rhoqo. Enanikade ivelufa luvulelekile ngokupheleleyo. Ushukunyiswayo ukuze nasemzimbeni zange iindawo ezibalaseleyo, yaye kummandla yokutsha kufuneka zigcinwe powder efini.

Phezu ucinezelo kwezinto sukube, ibhotile umgubo kufuneka ibhekiswe phantse eyayingqalene jet berhasi ngqo kumlanjana igesi. Xa zokucima kombane (kakade, de-akukhuthalele) ujolise jet powder kufuneka ekunene ukuya kumthombo ilangatye. Ubude bethuba ubomi isicima-mlilo (nge-avareji) uneminyaka elishumi.

Ukuze ukucima imililo kwi Class B (ucinezelo ulwelo) kunye zokucima yeklasi E (yombane) iintlobo kusetyenziswa umlilo carbon dioxide. Yepetroliyamu carbon dioxide na iarhente yalo engundoqo esebenzayo. Yokuba isandla-yabanjwa, mobile nezinto zokubhala. zokucima umlilo Manual kuwucima ufakelo lombane, ukuba amandla ombane ayi-1000V. ukusetyenziswa Mobile ekucimeni ulwelo olunokutsha walungiselela kwindawo ye square metres ezintlanu, njengokuba ubungakanani ezincinane zombane, leyo aphantsi ombane. Bona asetyenziswa kwimeko xa ayinqweneleki, umzekelo, ukusetyenziswa kwamanzi (e zobuciko, amaziko olondolozo kunye noovimba). Ubomi inkonzo zokucima umlilo carbon dioxide - ukuya kutsho kwiminyaka elishumi.

Phantse wonke zokucima umlilo amagwebu esebenzayo. Basebenzisa i alephuze amagwebu imichiza, efunyenwe izisombululo ze alkalis kunye acids, kwakunye air-mechanical, oluthi luqokelelane ukusuka isisombululo zolwelo sewayini umoya stream of carbon dioxide okanye nitrogen.

Kukho neentlobo enjalo zokucima umlilo, njengoko zetoti. zisetyenziselwa zokucima olunokutsha ulwelo, olunokutsha, kwakunye umbane, phantsi ombane, izinto ezahlukeneyo ngaphandle iintsimbi kwealkali izinto ioksijini-equlethe. Bona mda lokugcinwa seminyaka emihlanu.

Kukho olunye uhlobo isicima-mlilo - sokucima powder, ikepusi-1 oluzenzekelayo. Lusetyenziswa imililo udidi A, B, C no E. eziphambili feature Its - intsebenziswano oluzenzekelayo ngaphandle koncedo lomntu.

akayi kuba ngamnye akufuneki ukuba ukukhumbula ukuba kwimeko Ubhaqo umlilo kuyimfuneko, ukuba kunokwenzeka, ngoko nangoko umnxeba elorini umlilo.
