Intshayelelo enye

Amashishini esinyithi enziwe ngomgubo kaninzi kufuneka asebenzise i-hydrogen njengenkqubo yokunciphisa igesi xa utshisa i-workpiece.Nangona kunjalo, indlela yemveli yokuvelisa i-hydrogen ukusuka kwi-ammonia ukubola iyanda kwaye ayikwazi ukuhlangabezana neemfuno zelizwe kunye namashishini okuvelisa ukhuseleko ngenxa yeengozi ezinkulu zokhuseleko.Ukuze kuqinisekiswe ukhuseleko lwemveliso, amashishini kunye nabalawuli bokhuseleko bagxininise kwindlela yokuvelisa ngokukhuselekileyo kunye nokusetyenziswa kwegesi yokunciphisa i-hydrogen njengengqwalasela yophando kunye nokuphucula, kwaye kwezinye iindawo, amashishini anqatshelwe ngokucacileyo ukusebenzisa izixhobo zokubola i-ammonia.

Ngokweempawu zobuchwephesha bamashishini esinyithi somgubo, inkampani yethu iphuhlise uhlobo olutsha lwe-methanol yobushushu obuphantsi bokuqhekeka izixhobo zokuvelisa i-hydrogen, ngokukodwa ukubonelela amashishini esinyithi somgubo ngezixhobo ezikhuselekileyo nezithembekileyo zokuvelisa i-hydrogen, ukuze amashishini afumane igesi yenkqubo yokunciphisa i-hydrogen. ngokukhuselekileyo.Umgaqo wayo wokusebenza kunye neempawu zingeniswa ngolu hlobo lulandelayo.

2. Intshayelelo emfutshane kumgaqo wokusebenza wemveliso entsha ye-methanol yokuqhekeka kwe-hydrogen

1. I-reaction equation yokubola kwe-ammonia yesintu kwimveliso ye-hydrogen imi ngolu hlobo lulandelayo:

2NH3=3H2+N2 (iqondo lobushushu lokubola 780 ~ 850℃)

2. Ngokungafaniyo nenkqubo yokuvelisa i-hydrogen yendabuko yokubola kwe-ammonia, inkqubo entsha yokuvelisa i-hydrogen isebenzisa i-methanol cracking ukuvelisa i-hydrogen.I-Methanol cracking reaction kunye ne-carbon monoxide conversion reaction yenzeke nge-catalyst phantsi kweemeko ezithile zokushisa kunye noxinzelelo, okuyi-gas-solid catalytic reaction.

CH3OH=2H2+CO (iqondo lobushushu eliqhekezayo 240 ~ 280℃)

I-H2 kunye ne-CO eveliswa kukuqhekeka kokusabela kukunciphisa iigesi, i-CO inokudlala indima ekunciphiseni nasekukhuseleni i-workpiece eziko, phambi kwe-oven kunye nokusabela kwe-oksijini emoyeni ukuvelisa ukusasazwa kwe-CO2 emoyeni, emva kweminyaka emininzi. abavelisi babonakalise ukuba ukusetyenziswa komqhubi akuyi kubangela nayiphi na ingozi emzimbeni.

Iii.Iimpawu zokhuseleko lwenkqubo yokuvelisa i-methanol entsha ye-hydrogen 1. Iimpawu zokhuseleko lwezixhobo ezisetyenziswa kwimveliso ye-hydrogen zahlukile:

I-Methanol ilulwelo kwiqondo lobushushu begumbi, kwaye akulula ukuba iguquke ngokukhawuleza kwaye isasazeke emoyeni, ngelixa i-ammonia iyityhefu kunye negesi eyingozi enokutsha.I-ammonia yolwelo kulula ukuguquguquka kwaye isasazeke emoyeni, kwaye iziphumo zokuvuza azicingeki.Ke ngoko, amashishini kufuneka ajongane neenkqubo ezikhethekileyo zokusetyenziswa kwe-ammonia engamanzi ngaphambi kokuba isetyenziswe.IMethanol ayidleki kwaye ayikoyiki ukudibana nolusu lomntu.Lo gama nje ingaselwanga ngempazamo, ayisayi kuba yingozi ebantwini.I-ammonia iyadleka kwaye inomonakalo omkhulu eluswini nasemehlweni abantu, ngoko ke i-methanol ikhuselekile ukuyisebenzisa.

2. Ukugcinwa kwezinto ezisetyenziswayo kwimveliso ye-hydrogen ayifuni iinqanawa zoxinzelelo

I-ammonia yolwelo idinga iinqanawa zoxinzelelo ezikhethekileyo zokugcina, ezifuna ulawulo olungqongqo olufana nerekhodi, ukuqinisekiswa kunye nokugcinwa kweenqanawa zoxinzelelo zokugcinwa kwe-ammonia yolwelo ngokwemigaqo yolawulo lokhuseleko.I-Methanol inokugcinwa kuphela kwiqondo lokushisa eliqhelekileyo kunye nezikhongozeli zoxinzelelo, ngaphandle kwezikhongozelo ezikhethekileyo.

3. Umngcipheko wokuvuza kwegesi evuthayo uyagwenywa kwinkqubo yokuvelisa i-hydrogen

Ubushushu bokuqhekeka kweMethanol buphantsi.Ifuna kuphela i-240 ~ 280℃ ukuze i-methanol iqhekeke, engaphantsi kakhulu kunobushushu bokubola bokubola kwe-ammonia ukuvelisa i-hydrogen (ngaphezulu kwe-800℃).Ngale ndlela, into yokufudumala kunye ne-reactor ayiyi kutshiswa, kwaye i-hydrogen ayiyi kutshisa kwitanki kwaye ibaleke kuyo, ibangele ukuvutha okanye ukuqhuma.Ingozi yokuvuza kwegesi enokutsha iyaphetshwa ngokupheleleyo.

4. Iindleko zokusebenza kwe-methanol iqondo eliphantsi lobushushu besixhobo sokuqhekeka lisezantsi kuba i-methanol inobushushu obuphantsi bokuqhekeka (240 ~ 280 ℃), kwaye ubushushu bokusabela yi-1/3 kuphela yokubola kwe-ammonia, ke iindleko zokusebenza zingaphantsi kwesiqingatha se. ukuba izixhobo zokubola ammonia, ngoko ke kwakhona isixhobo ukonga amandla ngakumbi.

5. Ukuthengwa kweMethanol kulula

I-Methanol ifumaneka ngokulula naphi na kwimarike yasekhaya yemichiza.

Isine, isiphelo

Kolu hlalutyo lungasentla, kunokubonwa ukuba ukusetyenziswa kwesixhobo esitsha sokuvelisa i-methanol sokuqhekeka kwe-hydrogen kunezi nzuzo zilandelayo:

Ubushushu be-pyrolysis be-methanol buphantsi, ngoko ubomi benkonzo yesixhobo bude, bukhuselekile kwaye iindleko zokusebenza ziphantsi.IMethanol kulula ukuyithenga nokuyigcina.Kwangaxeshanye, i-methanol ayidleki, iguquguquke kwaye isasazeke, ngokungafaniyo ne-ammonia yolwelo, idinga izikhongozeli ezikhethekileyo zokugcina, kwaye xa sele ivuza, kuya kubakho ingozi enkulu.

Isixhobo esitsha sokuvelisa i-methanol ye-hydrogen yenkampani yethu e-shandong, eJiangsu, e-Zhejiang nakwezinye iindawo ezininzi zeshishini le-powder metallurgy eliza kusetyenziswa, kungekuphela nje ngokwanelisa ngokupheleleyo umoya wokunciphisa wezalathi zobugcisa be-hydrogen, ixabiso lemveliso liyancitshiswa, izixhobo ezitsha. kunye nenkqubo indlela akukho iingxaki ezintsha zokusingqongileyo, ingakumbi ekupheliseni ukhuseleko lweshishini ingozi efihliweyo kakuhle, Nceda amashishini ukuphucula umgangatho wolawulo lokhuseleko.Ulawulo lwemveliso ekhuselekileyo yeyona nto iphambili kumashishini.Sikholelwa ukuba ngokuthatha inxaxheba kwabasebenzi abaninzi, ukulungiswa okukhuselekileyo kunye nokusetyenziswa kwegesi yokunciphisa i-hydrogen kuya kucetywayo kwiifektri zemveliso yesinyithi somgubo, ukuze kuqinisekiswe ukuba amashishini enza igalelo elifanelekileyo kuluntu phantsi kwesiseko semveliso ekhuselekileyo.
