Kufotokozera Kwachidule:
Chothandizira kusintha kwa kutentha kochepa:
Kugwiritsa ntchito
CB-5 ndi CB-10 zimagwiritsidwa ntchito posintha kapangidwe kake ndi kupanga haidrojeni.
Kugwiritsa ntchito malasha, naphtha, gasi wachilengedwe ndi gasi wamafuta ngati chakudya, makamaka kwa osinthira kutentha kotsika kwa axial-radial.
Makhalidwe
Chothandizira chili ndi ubwino wa ntchito pa kutentha kochepa.
Kuchuluka kochepa kwa zinthu, pamwamba pa Copper ndi Zinc kumakhala kwakukulu komanso mphamvu yabwino ya makina.

ZnO desulfurization Catalyst yokhala ndi khalidwe lapamwamba komanso mtengo wopikisana
HL-306 ingagwiritsidwe ntchito pochotsa mpweya wotsalira kapena syngas ndi kuyeretsa mpweya wodyetsa
Njira zopangira za organic. Ndi yoyenera kugwiritsa ntchito kutentha kwapamwamba (350–408°C) komanso kotsika (150–210°C).
Imatha kusintha sulfure yosavuta yachilengedwe pomwe imatenga sulfure yopanda organic mu mpweya.
Njira yochotsera sulfurization ndi iyi:
(1) Kuyankha kwa zinc oxide ndi hydrogen sulfide H2S+ZnO=ZnS+H2O
(2) Kuyanjana kwa zinc oxide ndi mankhwala ena osavuta a sulfure m'njira ziwiri zomwe zingatheke.

4. Mkhalidwe Wabwinobwino Wogwirira Ntchito
Zakudya: mpweya wopangidwa, mpweya wa m'munda wamafuta, mpweya wachilengedwe, mpweya wa malasha. Imatha kuchiza mpweya ndi sulfure yopanda chilengedwe ngati wokwera kwambiri
23g/m3 yokhala ndi digiri yoyeretsera yokwanira. Imathanso kuyeretsa mpweya ndi mpweya wochepa mpaka 20mg/m3.
sulfure yachilengedwe ngati COS mpaka pansi pa 0.1ppm.
5. Kukweza
Kuzama kwa kukweza: Kuchuluka kwa L/D (min3) kukulangizidwa. Kukhazikitsa ma reactor awiri motsatizana kungathandize kuti ntchito igwiritsidwe ntchito bwino
kugwira ntchito bwino kwa adsorbent.
Njira yokwezera:
(1) Tsukani choyeretseracho musanayikemo;
(2) Ikani ma gridi awiri osapanga dzimbiri okhala ndi maukonde ang'onoang'ono kuposa adsorbent;
(3) Ikani wosanjikiza wa 100mm wa Φ10—20mm refractory spheres pa ma gridi osapanga dzimbiri;
(4) Thirani chotsukira kuti muchotse fumbi;
(5) Gwiritsani ntchito chida chapadera kuti muwonetsetse kuti adsorbent m'bedi ikugawidwa mofanana;
(6) Yang'anani kufanana kwa bedi pamene mukunyamula katundu. Ngati pakufunika kugwiritsa ntchito mkati mwa reactor, mbale yamatabwa iyenera kuyikidwa pa adsorbent kuti wogwiritsa ntchito ayimepo.
(7) Ikani gridi yosapanga dzimbiri yokhala ndi maukonde ang'onoang'ono kuposa adsorbent ndi wosanjikiza wa 100mm wa Φ20—30mm refractory spheres pamwamba pa bedi la adsorbent kuti mupewe kutsekeka kwa adsorbent ndikuwonetsetsa kuti
kugawa bwino kwa mpweya wa gasi.
6. Kampani yoyambitsa
(1) Sinthani dongosolo ndi nayitrogeni kapena mpweya wina wopanda mpweya mpaka kuchuluka kwa okosijeni mu mpweyawo kukhale kochepera 0.5%;
(2) Yatsani mtsinje wa chakudya ndi nayitrogeni kapena mpweya wa chakudya pansi pa kupanikizika kozungulira kapena kokwera;
(3) Liwiro la kutentha: 50°C/h kuchokera kutentha kwa chipinda mpaka 150°C (ndi nayitrogeni); 150°C kwa maola awiri (pamene chotenthetsera chili
kusinthidwa kukhala mpweya wodyetsa), 30°C/h pa kutentha kopitilira 150°C mpaka kutentha kofunikira kufikire.
(4) Sinthani kuthamanga kwa mpweya pang'onopang'ono mpaka kuthamanga kwa mpweya kukwaniritsidwe.
(5) Pambuyo potenthetsa ndi kukweza mphamvu, makinawo ayenera kuyendetsedwa kaye ndi theka la katundu kwa maola 8. Kenako kwezani
katundu pang'onopang'ono pamene ntchitoyo yakhazikika mpaka ntchito yonse itatha.
7. Kutseka
(1) Kutuluka kwa gasi (mafuta) mwadzidzidzi.
Tsekani ma valve olowera ndi otulutsira. Sungani kutentha ndi kuthamanga. Ngati pakufunika, gwiritsani ntchito nayitrogeni kapena haidrojeni-nayitrogeni
mpweya kuti usunge kuthamanga kwa mpweya kuti upewe kuthamanga kwa mpweya koipa.
(2) Kusintha kwa desulfurization absorbent
Tsekani ma valve olowera ndi otulutsira. Chepetsani kutentha ndi kuthamanga pang'onopang'ono kuti zigwirizane ndi momwe zilili. Kenako patulani
Chotsani mpweya wochotsa sulfurization kuchokera ku makina opangira. Bwezerani mpweya mu riyakitala mpaka mpweya wokwanira kufika pa >20%. Tsegulani riyakitala ndikutulutsa adsorbent.
(3) Kukonza zida (kukonzanso)
Tsatirani njira yomweyi monga momwe tawonetsera pamwambapa koma kupanikizika kuyenera kuchepetsedwa pa 0.5MPa/10min ndi kutentha.
kutsika mwachibadwa.
Chotsitsa madzi chotsukidwa chiyenera kusungidwa m'magawo osiyana. Unikani zitsanzo zomwe zatengedwa kuchokera pagawo lililonse kuti mudziwe
udindo ndi nthawi ya ntchito ya adsorbent.
8. Kuyendera ndi kusunga
(1) Chogulitsacho chimayikidwa m'migolo yapulasitiki kapena yachitsulo yokhala ndi pulasitiki kuti chiteteze chinyezi ndi mankhwala.
kuipitsidwa.
(2) Kugubuduka, kugundana ndi kugwedezeka mwamphamvu kuyenera kupewedwa panthawi yoyendetsa kuti zisawonongeke
chokometsera.
(3) Chogulitsacho chiyenera kutetezedwa kuti chisakhudze mankhwala panthawi yonyamula ndi kusungira.
(4) Chogulitsacho chingasungidwe kwa zaka 3-5 popanda kuwonongeka kwa makhalidwe ake ngati chatsekedwa bwino.
Kuti mudziwe zambiri zokhudza zinthu zathu, chonde musazengereze kundilankhulana nane.
