Unganidza ikozvino!Matambudziko akajairika uye kurapwa kwenitrogen jenareta ane kuchena kusiri kusvika pachiyero (Chikamu 2)
Sezvatinoziva tese, kuchena kweiyo nitrogen jenareta kwakakosha pakugadzira.Kusachena kwenitrogen hakungokanganisa kutaridzika kwewelding, asiwo kunotungamirira kune chigadzirwa oxidation uye kukanganisa kwemaitiro, uye kunotokonzera njodzi huru dzekuchengetedza mumaindasitiri emakemikari nemoto.
Chinyorwa chakapfuura "Matambudziko Akajairika uye Kurapa kweKusina-chiyero Kuchena kweNitrogen Jenereta" yakagovana hukama pakati pekusachena kwenitrogen mumajenareta enitrogen uye kutadza kwemagetsi kwemidziyo pachayo uye masisitimu anotsigira, pamwe nemhedzisiro nemhinduro.Muchinyorwa chino, isu Tichawedzera kugovera zvinhu zvakawoma kubva kune zvekunze zvinhu: pesvedzero yemidziyo yekushandisa nharaunda tembiricha, yakadzvanywa yemhepo dova nzvimbo (unyoro hwemukati), uye yakamanikidzwa mhepo yakasara oiri pakuchena kwenitrogen jenareta uye kushanda kwemidziyo.

Midziyo inogadzira nitrogen yakagadzirwa nemamiriro ekushanda akadzikama emidziyo mupfungwa, kazhinji muhuwandu hwe0-45 ° C, zvinoreva kuti midziyo inogona kuita kazhinji mukati meiyi tembiricha.Pane zvinopesana, kana ikashandiswa kunze kweyakagadzirirwa ambient tembiricha, zvinounza matambudziko akadai sekuderera kwekuita uye mwero wekutadza kwakanyanya.
Kana iyo ambient tembiricha inodarika 45 ° C, tembiricha yekuburitsa yemhepo compressor ichave yakanyanya kukwira, izvo zvichawedzera mutoro pane yakaoma yakaoma.Panguva imwecheteyo, inogona kuita kuti muomesi wechando ufambe pakupisa kwakanyanya.Iyo dova yemhepo yakamanikidzwa haigone kuvimbiswa, iyo ichakanganisa zvakanyanya nitrogen jenareta.effect.Pasi pemamiriro ekuchena kwakafanana, kuyerera kwehuwandu hwe nitrogen huchadonha nepamusoro pe20%;kana chiyero chekuyerera kwekugadzirwa kwe nitrogen chinoramba chisina kuchinjwa, kuchena kwe nitrogen gasi hakuzosangana nezvinodiwa zvekugadzira.Kuburikidza nerabhoritari yekuyera tembiricha yakakwira uye yakaderera, takaona kuti kana tembiricha yakadzika yadzikira pane -20°C, mamwe magetsi haagone kutangwa, kana kuti chiitiko chacho hachina kumira zvakanaka, izvo zvinozoita kuti jenareta renitrogen ritadze kutanga nekushanda.
mhinduro
Kuti uvandudze nharaunda yekamuri yekombuta, iyo mhepo yekufefetera inofanirwa kuvandudzwa muzhizha, uye mamiriro ekupisa anofanirwa kuwedzerwa munguva yechando kuve nechokwadi chekuti ambient tembiricha yekamuri yekombuta iri mukati memhando inonzwisisika.

Hunyoro hwehunyoro (pressure dow point) mumhepo yakatsikirirwa hunokanganisa zvakananga pane jenareta renitrogen/carbon molecular sieve, saka jenareta renitrogen rine zvinodiwa zvakasimba pakunaka kwemhepo yakatsikirirwa kumberi.
Iyo chaiyo kesi yekukanganisa kwekubviswa kwemvura uye kuparadzaniswa kwemvura mhedzisiro yeinotonhora dryer pane nitrogen jenareta:
Case 1: Mushandisi haana kuisa otomatiki drainer pane tangi yekuchengetedza mhepo yemhepo compressor, uye haana kudonhedza mvura nguva nenguva, zvichikonzera hunyoro hwakakura mumhepo inopinza yeinotonhora, uye yechitatu-nhanho sefa pa. iyo mhepo inopinza uye yekubuda kweiyo inotonhora yekuomesa haina kuisa drainer Uye yenguva dzose manyorero emvura, zvichikonzeresa yepamusoro yemvura yemukati muhurongwa, zvichikonzera iyo activated kabhoni sefa yakaiswa kumucheto kumashure kuti itore mvura uye kugadzira zvidhinha kuvhara mweya wakamanikidzwa. pombi, uye kudzvanywa kwekutora kunoderedzwa (kusakwana kutora), zvichikonzera kuchena kwejenareta renitrogen kusasangana nechiyero.Dambudziko rakagadziriswa nekuwedzera iyo drainage system mushure mekushandura.
Nyaya yechipiri: Iyo yekuparadzanisa mvura yemushandisi inotonhora yekuomesa haina kunaka, zvichiita kuti mvura inotonhorera isapatsanurwe nenguva.Mushure mokunge mvura yakawanda yemvura inopinda mujenareta ye nitrogen, 2 solenoid valves inoputsika mukati mevhiki, uye mukati mekona yekona yevhavha piston yakakanganiswa zvachose.Imvura yemvura, iyo inokonzera kuti piston chisimbiso chiparadze, zvichiita kuti valve ishande zvisina kunaka, uye jenareta ye nitrogen haigoni kushanda zvakanaka.Mushure mekutsiva iyo yekuomesa chando, dambudziko rakagadziriswa.
1) Kune ma micropores pamusoro pekabhoni molecular sieve, ayo anoshandiswa adsorb okisijeni mamorekuru (sezvinoratidzwa mumufananidzo).Kana iyo mvura iri mumhepo yakamanikidzwa ichirema zvakanyanya, ma micropores e molecular sieve anodzikira uye guruva riri pamusoro peiyo molecular sieve rinodonha, iro rinovharira ma micropores esefa uye kukonzera iyo unit uremu Carbon molecular sieves. haigone kuburitsa kuyerera kwenitrogen uye kuchena kwenitrogen kunodiwa nechiyero.
Zvinokurudzirwa kuti vashandisi vaise adsorption dryer pakupinza kweiyo nitrogen jenareta kuti vaderedze zviri mukati memvura yemhepo yakamanikidzwa uye kuona kuti iyo kabhoni molecular sieve haina kusvibiswa nemafuta anorema uye inorema mvura.Kazhinji, hupenyu hwebasa hwema molecular sieve hunogona kuwedzerwa nemakore 3-5 (maererano nehutsanana).

Mhedzisiro yemafuta ari mumhepo yakamanikidzwa pane nitrogen jenareta / molecular sieve:
1) Kune chero mhando / chimiro che molecular sieve, izvo zvisingakoshi zvikamu zvinotariswa kunze kuburikidza ne micropores pamusoro peiyo molecular sieve kuti tiwane zvinhu zvatinoda.Asi ese masefa emamorekuru anotya kusvibiswa kwemafuta, uye kusvibiswa kwemafuta kwakasara zvachose kusvibiswa kusingadzoreki kune masefa emamorekuru, saka kupinza kwejenareta yenitrogen kune zvinodikanwa zvemafuta.
2) Sezvinoratidzwa mumufananidzo uri pamusoro, mavara emafuta anovhara mamicropores ari pamusoro pesefa yemamorekuru, zvichiita kuti mamorekuru eokisijeni asakwanise kupinda mumamicropores uye adsorbed, zvichikonzera kudzikira kwekugadzirwa kwenitrogen, kana pasi pemamiriro ekunze. kuve nechokwadi chekuyerera kwekutanga, iyo nitrogen kuchena kuchave isina kukodzera mukati memakore mashanu.
Nzira dzekuvandudza dzematambudziko ari pamusoro: Teerera kumhepo yekamuri yemuchina, kuderedza tembiricha yepakati, uye kuderedza huwandu hwemafuta akasara mumhepo yakamanikidzwa;simbisa dziviriro kuburikidza nezvinotonhora zvekuomesa, zvekuyamwa dryer, mafirita, uye activated kabhoni degreasers;nguva dzose kutsiva / kuchengetedza midziyo yepamberi yejenareta yenitrogen, Kuve nechokwadi chemhando yemhepo yakamanikidzwa inogona kudzivirira zvakanyanya uye kuwedzera hupenyu hwesevhisi yenitrogen jenareta uye kushanda kwekabhoni molecular sieves.

Kupfupisa: zvinhu zvekunze senge tembiricha yekamuri yemuchina, iyo yemvura uye zvirimo mumafuta emhepo yakamanikidzwa zvinokanganisa mashandiro eiyo nitrogen kugadzira michina, kunyanya inotonhora yakaoma, yekuyamwa yakaoma uye sefa pamberi peiyo. nitrogen kugadzira muchina uchakanganisa zvakananga iyo nitrogen kugadzira michina.Iko kushandiswa kweiyo nitrogen jenareta, saka sarudzo yemhando yepamusoro uye inoshanda yekuomesa michina inonyanya kukosha kune nitrogen jenareta.
Vazhinji vagadziri ve nitrogen jenareta havaburitse kumberi-kumagumo akatsikirirwa mhepo yekuchenesa michina.Kana iyo nitrogen jenareta system ikakundikana, zviri nyore kune vanogadzira nitrogen jenareta uye vanogadzira dryer shirk mumwe nemumwe uye kwete kutora mutoro kune mumwe nemumwe.
Semutengesi akanakisa wezvimisikidzwa zvemagetsi system zvigadzirwa, EPS ine yakazara chigadzirwa cheni, iyo inogona kupa vatengi seti yakazara yemidziyo yakadai seinotonhora inoomesa, suction dryer, mafirita, majenareta enitrogen akazvimiririra uye anogadzirwa, emhando yepamusoro Compressed air purification. zvigadzirwa zvakashongedzerwa nemhando yepamusoro nitrogen jenareta, kuitira kuti vatengi vagone kutenga uye kushandisa nechivimbo!
