Hoʻohana ʻia kēia huahana no ka hoʻomaloʻo hohonu ʻana o ke kinoea a i ʻole ka pae wai o nā petrochemical a me ka hoʻomaloʻo ʻana i nā mea kani.
25kg i ulana ʻeke / 25kg pepa pahu pahu / 200L pahu hao a i ʻole ke noi a ka mea kūʻai aku.
Loaʻa i ka alumina hoʻāla ʻia nā hiʻohiʻona o ka mana adsorption nui, kahi ākea kikoʻī nui, ikaika kiʻekiʻe, a me ke kūpaʻa wela maikaʻi. mea waiwai. Loaʻa iā ia kahi pilina ikaika, he mea ʻawaʻawa ʻole, non-corrosive maikaʻi desiccant, a he kiʻekiʻe kona mana paʻa. Hoʻohana ʻia ia e like me adsorbent, desiccant, catalyst a me ka mea lawe i nā kaʻina hana e like me ka petroleum, fertilizer chemical a me ka ʻoihana kemika.
ʻO ka alumina hoʻāla ʻia kekahi o nā huahana kemika inorganic i hoʻohana nui ʻia ma ka honua. ʻO nā waiwai o ka alumina i ho'āʻia e weheweheʻia ma lalo nei: He kūpaʻa maikaʻi ka alumina hoʻonāuki a he kūpono ia ma keʻano he desiccant, he catalyst carrier, fluorine removal agent, pressure swing adsorbent, special regeneration agent for hydrogen peroxide, etc. ma ke ano he catalyst a me ka mea lawe catalyst.
Hoʻohana ʻia ka alumina i hoʻohana ʻia ma ke ʻano he desiccant, hoʻohana nui ʻia i ka ʻoihana hoʻomaloʻo ʻana i ka ea, ʻo nā mea hoʻomaloʻo ea ea i kahi kaomi hana, ma lalo o 0.8Mpa, kahi e koi ai i ka ratio alumina hoʻāla e loaʻa ka ikaika mechanical maikaʻi, inā ʻoi aku ka ikaika mechanical. haʻahaʻa, maʻalahi ka pauka, ka pauka a me ka hui wai e hoʻopaʻa pololei i ka pipeline mea hana, no laila, ʻo kahi hōʻailona koʻikoʻi o ka alumina i hoʻohana ʻia ma ke ʻano he desiccant ka ikaika, nā mea hoʻomaloʻo ea ea, maʻamau ʻelua mau pahu, ʻelua mau pahu hana alternately, ʻoiaʻiʻo. he adsorption saturation → analytic pōʻaiapili kaʻina hana, desiccant ka nui adsorption wai, akā ma lalo o ka realistic hana kūlana, ea kaomi hoʻomaloʻo lako puna e loaʻa ai ka aila, ka'ōpala a me nā mea haumia'ē aʻe, keia mau mea e pili pono i ke ola lawelawe o activated alumina adsorbent, no ka mea. alumina mea porous adsorption mea, maoli adsorption polarity o ka wai, aila adsorption mea no hoi maikaʻi loa, akā, aila e pono plug ho'ā 'ia alumina adsorption pore, no laila, i ka lilo o adsorption ano, aia ka rust, ka lepo i ka wai, pili i ka ili o alumina ho'ā 'ia, E hana i ka alumina ho'ā 'ia pololei lilo hana, no laila, i loko o ka alumina ho'ā 'ia e like me ka desiccant hoʻohana, e ho'āʻo e pale aku me ka aila, ka'ōpala, ho'ā 'ia alumina adsorbent e like me desiccant maʻamau hoʻohana ola o 1 ~ 3 makahiki, ka hoʻohana maoli e maloʻo kinoea. wahi hau e hoʻoholo ai inā e pani i ka alumina hoʻā. ʻO ka mahana hou o ka alumina i hana ʻia ma waena o 180 ~ 350 ℃. ʻO ka maʻamau, piʻi ka mahana o ka hale kiaʻi alumina i 280 ℃ no 4 mau hola. Hoʻohana ʻia ka alumina i hoʻāla ʻia e like me ka lāʻau lapaʻau wai, a hoʻohana ʻia ka hopena alumini sulfate e like me ka regenerator. ʻO ka hoʻonā hoʻonā o ka alumini sulfate regenerator he 2 ~ 3%, ʻo ka alumina i hoʻāla ʻia ma hope o ka adsorption saturation i hoʻokomo ʻia i loko o ka alumini sulfate solution soaking, hoʻolei i ka hopena, holoi me ka wai maʻemaʻe 3 ~ 5 mau manawa. Ma hope o ka hoʻohana lōʻihi, he melemele ka ʻili alumina i hoʻāla ʻia a hoʻemi ʻia ka hopena defluorination, ʻo ia ke kumu o ka adsorption o nā haumia. Hiki ke mālama ʻia me 3% hydrochloric acid no 1 manawa a laila hoʻoponopono hou ʻia e ke ʻano o luna.
