Coke eziko neebhetri: isixhobo, isimiso ukusebenza, ukuqeshwa. Coke Production Technology

kushishino Metallurgical nje akunakwenzeka ngaphandle kokusebenzisa coke, nto leyo inika amandla ukunyibilikisa ekrwada yentsimbi aqulethe kwi nomphini eziko kuqhuma. Nangona kunjalo, inkqubo yokuvelisa coke kunokuba onzima kunye ixesha elide. kwiiyunithi zemfundo eneemfuno ezizodwa mveliso ebizwa ngokuba "coke iibhetri eziko" zakhelwe uyidala. On wezixhobo zabo, ukuqeshwa kunye neempawu ziza kuxutyushwa kweli nqaku.

definition

Coke eziko iibhetri - izakhiwo metallurgical, injongo ogama main ukuvelisa imali olufunwayo coke ukuthutha emva kulawulo ithambeka. La maziko ziyahluka ngokwemigaqo ubungakanani phakathi kwabo, kodwa kunjalo, ubukhulu yabo kakhulu umxhelo.

design

Icebo of iibhetri coke elandelayo. Izinto eziphambili zezi yamaziko ezi-ebizwa ngokuba carbonization gumbi. Kubo kukho i ekrwada inkqubo ingqokelela eziphathekayo. Coking yokwayama kweli ziko, kukho ngaphezu elinesibini. Kwakhona iiseli ezibalulekileyo Ibhetri ingagcwaliswa okanye ukufunda ixesha zokufudumeza apho kwenzeka amafutha yokutsha. Uqikelelo Ubukhulu linear lwegumbi coking zezi zilandelayo:

• Ubude - ukusuka neemitha ezingama-12 ukuya kwali-16.
• Height - iimitha 4-5.
• Ububanzi - 400-450 mm.

Ngokubanzi, isakhiwo, apho ibhetri coke unako ukusebenza ngokuqhubekayo ixesha elide, iquka la macandelo alandelayo:

• Ukufumana hopper, yona efumana amalahle ebomvu.
• Branch ukuxuba, uwaphule namalahle.
• Distribution inqaba.
• Sibona yokuphatha.
• egumbini coking.
• Ejector coke.
• icima imoto.
• icima inqaba.
• Iqonga apho wagqiba ostuzhennoy lingatshajiswanga imveliso.

Ukuveliswa somlilo coke efanayo kakhulu ngokubanzi sakhiwa:

• Ikhamera ukukhuphela intlawulo wamalahle.
• Le zokubasa ulwahlulo kunye nenkqubo ubushushu yemijelo.
• Inkqubo lonikezelo lwerhasi kunye umoya.
• A regenerator ukufudumeza umoya kunye output iigesi flue.
• Iivelufa kunye neendlela.

ngezigaba

Coke iibhetri eziko, kuxhomekeke indlela yokusebenza na inyathelo ngamaxesha athile ngokuqhubekayo. Ezi iibhetri kungenziwa shushu:

• gas udubulo somlilo kakhulu.
• Kuphela coke igesi oveni.
• Umxube segesi udubulo somlilo coke.

ibhetri ukufudumeza yesekethe ziquka:

• Shintsho channel, ngalo irhasi kufuneka ithuba kuwa phakathi piers.
• channel ezidityanisiwe ukuze recirculation.

Irhasi ukufudumeza ibhetri kukhutshwa kwalo iinguqulelo ezimbini:

• Icala xa coke igesi oveni sele kornyuru (gas ukuhanjiswa channel), kunye negesi lomoya udubulo neziko - on amajelo eziko regenerator.
• Ezantsi inethweki lonikezelo umoya ezikhethekileyo.

A amagama ambalwa malunga regenerator

Esi sixhobo ezizodwa transfer ubushushu yenza transfer ubushushu medium udibana Imiphezulu ephawulwe ngokucacileyo eziko coke. Kubalulekile ukuqaphela ukuba yenethiwekhi ubushushu eshushu kumo udonga ebandayo kunye esatsiba, yaye emva koko nabo transfer ubushushu ophethe ubushushu abandayo kakade.

Kukho ezinye iintlobo ze kubananisi ubushushu, ezo zibizwa ngokuba "recuperators". Kwezi neencindi ashushu nabandayo transfer nobushushu, amandla abelane nabanye uthango therebetween ekhethekileyo akhiwa. Kule kuhla kuqala phantsi sokuqukuqela serhasi eshushu, kwaye ke kukho umsebenzi shintsho izivingco, apho ezantsi ukuya phezulu liqalisa nokunyuka komoya sele ezibandayo.

Ndlela uqoqosho amafutha kwimveliso ye coke

inkqubo Coking ngokwaso kakhulu umbane kakhulu, nto leyo ibangelwa ukusetyenziswa izixa ezikhulu kakhulu amafutha. Ngoko ke, le ndlela ilandelayo isetyenziselwe ukunciphisa izinga tu;

• Ukusebenzisa owomileyo coke technology ucimayo. Ngenxa imveliso amandla thermal lusetyenziselwa ukufudumeza ngomphunga okanye emanzini. Ngokukodwa, enye ngetoni ugqibile coke ifunyenwe malunga 1 GJ ubushushu ngohlobo zomphunga.
• regenerators maxesha yokuyikhangela ubushushu eliphezulu iimveliso komlilo. Umzekelo, ukuba kunokwenzeka ukwandisa indawo ubushushu kwi esatsiba.
• Ukubalwa ixesha eliphezulu lekhefu phakathi semigudu kokusebenzisa. Noxa kunjalo, ukuba kaninzi ukuba ushintshele, ngoko ekugqibeleni kuya kunika ithuba ukunciphisa isixa regenerators kunye nelahleko ubushushu kubo. Nakuba kunjalo, kufuneka ngokuqinisekileyo kuqatshelwe ukuba umsebenzi vana rhoqo kakhulu kuya ekugqibeleni kukhokelela umonakalo zazo ngokukhawuleza umthwalo ezongezelelweyo kuzo zonke amacandelo anxulumene kunye abaza kuzisebenzisa.
• Le ubushushu intlawulo kunye coke ucimayo owomileyo yenziwa ngexesha elinye.

inkqubo

Imveliso Coke kunzima kakhulu. Ngoko ke, ukuba baqonde ukuba isebenza njani ehlabathini yokwenene, kuyimfuneko ukwazi umjikelo zeteknoloji njengoko zichazwe kangangoko kunokwenzeka.

imveliso shop coke njalo iqala enqabeni wamalahle. Lenza kuwo ekrwada. Emazantsi inqaba, kukho izivalo ezikhethekileyo. Ngabo, yamalahle ithuthelwe ekufumaneni kumatshini hopper uglezagruzochnoy. Ukuze ngaphandle ilahle usixhome ngaphakathi nenqaba ecaleni ukuphakama kwayo yonke wachaza ngomoya leyo wondla pulses discontinuous neqinisekisa uthambisa nokunamathela ezindongeni Tower kwibhetshi. Tower ngokuqinisekileyo uya kuzaliswa hayi ngaphantsi kwesibini kwisithathu-of umthamo wayo.

Umatshini Uglezagruzochnaya zigcwaliswe mhlawumbi ngokomthamo okanye ngokobunzima. Inkqubo yokuzaliswa yayo ilawulwa iintsimbi. Amalahle kondliwa eziko ngoko nangoko emva kokuba kunikezelo coke ogqityiweyo. Xa oku kwenzeka intlawulo kudla nge phezulu. Ngexesha kulayishwa coke eziko umntu onoxanduva - ukukhuhla - kuquka iziko umqokeleli kanye irhasi kwaye usebenze ngenaliti. Inkqubo iyonke iyalayisha siyakrazula imizuzu emithathu ukuya kwezintandathu.

Eziko ke ngci ngocoselelo, ze uqale inkqubo zokufudumeza kwibhetshi. coke technology coke battery inika iinkqubo ubushushu zilandelayo:

• E 100-110 ° C udlula amalahle yokomisa.
• Xa uluhlu 110 ° C - 200 ° C kunye gigrosokpicheskaya yabelwe colloidally wambopha iigesi ukufuma occluded.
• Kwi 200 ° C - 300 ° C nokuphuma kwemali ukulungiselela thermal, nto leyo sikhatshwa ukuyilwa iimveliso sukube phansi thermal kunye cleavage yamaqela thermally labile ioksijini-equlethe.
• 300-500 ° C - umqolo lobushushu apho kukho urhulumente yeplastiki. Ngokunzima bakhululwa igesi kunye nomphunga, isigaba ulwelo usenziwa.
• 550-800 ° C - coking medium of. Synthesis kwakhula.
• 900-1100 ° C - lobushushu High carbonization.

Kwathunyelwa oveni coke

Coke Ibhetri eziko, lo mgaqo ichazwa kweli nqaku kufuna akukho uqeqesho olulodwa phambi kokuba kukhutshwe imveliso ogqityiweyo ivela kuyo. Akukho nemizuzu ngaphantsi kwe amabini phambi kokuba kunikezelo lezonka qho mandatory ndinqumle ukusuka plenum kwaye ingxelo kwi-atmosfera ngokuvula isiciko phayiphu.

Emva koko, ukususwa emnyango oveni kwaye ejection lwenziwa ikhokhonathi egumbini quencher nqwelo ngesibonda okhethekileyo. Kulo mzekelo, ukuba ngenxa yaso nasiphi na isizathu kukho ukulibaziseka kule coke okucwangcisiweyo ngaphezu kwemizuzu elishumi, emnyango kufuneka abekwe umva endaweni. Kuyinto ngaphambi ukuvula elingaphandle risers kuyathintelwa, njengoko oku kungadala yokuwa kakhulu ingaphakathi ngaphakathi ibhetri. Ukongezelela koko, iingcango amaziko kufuneka nakanjani makukhutshwe grafayithi kunye nentlaka phambi nasemva kokuba inkqubo yokukhupha imveliso ogqityiweyo. Coke icima kwimoto ekhethekileyo - inkqubo yogunyaziso, kuba ngaphandle kwalo msebenzi wayigqiba coke ungaphinda kwanokubuyisela.

coke iibhetri ubalo ubonelela ukuba iziko kufuneka babe ixesha yokusebenza kunye nokugcina. Ngexesha lomjikelo ukusebenza ikhutshwa phandle coke ukutyhala, kwaye ngexesha ulondolozo - wenziwe nokugcina zonke oomatshini kunye nezixhobo, ukucocwa, njalo njalo.

umongo

Ngelo lokuqala coking amalahle iyoma, zonke iigesi adsorbed zisuswe kulo kunye yokubola iqala. Ngelo xesha kwamalahle inguqu karhulumente zeplastiki iqala sintering - nkqubo leyo izigqibo kumjikelo coking yonke. Kwisigaba sesithathu ivavanywa calcination kunye nezo-lukhuni. It iimpompo lo wokomelela kwiindimbane viscous ekukhuthazeni igesi besendleleni eya plenum igesi, ngaloo ndlela bakha coking uxinzelelo, nto leyo mayenziwe uyahlawulwa shrinkage le coke sele kwakhiwa.

ukulondolozwa

"Kutheni na ukuba ukunqanda amabhetri coke?" - ukuba umbuzo onjalo ngokufuthi yiva umntu, kude nezo kunye bokuqonda nemveliso coke. Eyona nto kukuba ezi yunithi luyilwe ukusebenza phantsi kweemeko ezithile (amaqondo obushushu aphezulu, lingonakali njalo njalo. D.) Yaye xa kukho yokumisa nezingacwangciselwanga, ngaphandle uqeqesho olufanelekileyo, ezi nasezimbizeni bayakwazi ukuba ulahlekelwe wamatye yakho engaphakathi, apho itshatyalaliswa nje. Noko ke, xa kusenziwa maxa wambi kufuneka ukuxhoma ukusebenza coke oven ibhetri kwaye enze amanyathelo olondolozo opredlenii. Indlela esebenza - ukuchaza ixesha elide kakhulu, siya kuphela mfuneko bonisa ukuba kukho ekuthiwa "opholileyo" kunye "ashushu" zolondolozo. Inguqulo kubo ukuba bakhethe - akuzisi ngokwayo Manager, ngokuxhomekeke meko kunye nezizathu zokumiswa ukusebenza kweyunithi.
