Kupita patsogolo kwaukadaulo wopanga ma haidrojeni ndi kusanthula zachuma - Kupanga hydrogen mu cell alkaline electrolytic cell

Kupanga kwa alkaline cell haidrojeni ndiukadaulo wopanga ma electrolytic hydrogen. Selo ya alkaline ndi yotetezeka komanso yodalirika, yokhala ndi moyo kwa zaka 15, ndipo yakhala ikugwiritsidwa ntchito kwambiri pamalonda. Kugwira ntchito bwino kwa cell ya alkaline nthawi zambiri kumakhala 42% ~ 78%. M'zaka zingapo zapitazi, maselo amchere a alkaline apita patsogolo mbali ziwiri zazikulu. Kumbali imodzi, kuyendetsa bwino kwa maselo kwakhala bwino ndipo ndalama zogwirira ntchito zokhudzana ndi kugwiritsa ntchito magetsi zachepetsedwa. Kumbali ina, kachulukidwe kakali pano akuwonjezeka ndipo mtengo wandalama umachepa.

Mfundo yogwirira ntchito ya alkaline electrolyzer ikuwonetsedwa pachithunzichi. Batire ili ndi maelekitirodi awiri olekanitsidwa ndi diaphragm yoletsa mpweya. Kuphatikiza kwa batri kumamizidwa mumchere wambiri wamchere wamadzimadzi a electrolyte KOH (20% mpaka 30%) kuti muwonjezere ma ionic conductivity. Mayankho a NaOH ndi NaCl amathanso kugwiritsidwa ntchito ngati ma electrolyte, koma sagwiritsidwa ntchito nthawi zambiri. Choyipa chachikulu cha ma electrolyte ndikuti amawononga. Selo imagwira ntchito pa kutentha kwa 65 ° C mpaka 100 ° C. Cathode ya selo imapanga haidrojeni, ndipo zotsatira za OH - zimayenda kudzera mu diaphragm kupita ku anode, kumene zimaphatikizananso kupanga mpweya.

Maselo apamwamba a alkaline electrolytic ndi oyenera kupanga ma haidrojeni ambiri. Maselo amchere electrolytic opangidwa ndi opanga ena mkulu kwambiri wa haidrojeni kupanga mphamvu pa (500 ~ 760Nm3/h), ndi lolingana mowa mphamvu 2150 ~ 3534kW. Pochita, pofuna kupewa kupangidwa kwa magesi oyaka moto, zokolola za hydrogen zimangokhala 25% mpaka 100% yazomwe zimawerengedwa, kuchuluka kovomerezeka komweku kuli pafupifupi 0.4A / cm2, kutentha kwa ntchito ndi 5 mpaka 100 ° C, ndipo kuthamanga kwambiri kwa electrolytic kuli pafupi ndi 2.5 mpaka 3.0 MPa. Kuthamanga kwa electrolytic kukakwera kwambiri, mtengo wandalama umakwera ndipo chiwopsezo chopanga kusakaniza kwa gasi woyipa chimakula kwambiri. Popanda chipangizo chothandizira choyeretsera, kuyera kwa haidrojeni wopangidwa ndi alkaline cell electrolysis kumatha kufika 99%. Alkaline electrolytic cell electrolytic madzi ayenera kukhala oyera, pofuna kuteteza elekitirodi ndi ntchito otetezeka, madutsidwe madzi ndi zosakwana 5S/cm.
