Kushandiswa/Kurongedza
Chigadzirwa ichi chinoshandiswa pakuomesa zvakanyanya gasi kana chikamu chemvura chemakemikari epetrochemicals uye kuomesa zvishandiso.
Bhegi rakarukwa re25kg/dhiramu repepa re25kg/dhiramu resimbi re200L kana zvichienderana nechikumbiro chemutengi.
Hunhu hweMaumbirwo eAlumina yakabatidzwa
Alumina yakabatidzwa ine hunhu hwekukwanisa kunyudza mvura yakawanda, nzvimbo yakakura chaiyo, simba rayo guru, uye kugadzikana kwakanaka kwekupisa. Ine hukama hwakasimba, idesiccant isingakuvadzi, isingaparadzi, uye kugona kwayo kusingachinji kwakakwira. Inoshandiswa seadsorbent, desiccant, catalyst uye carrier mumabasa akawanda ekuita senge petroleum, chemical fertilizer uye chemical industry.
Alumina yakakamurwa ndeimwe yemakemikari asingasanganisike anoshandiswa zvakanyanya pasi rose. Hunhu hwealumina yakakamurwa hwatsanangurwa pazasi: Alumina yakakamurwa ine kugadzikana kwakanaka uye yakakodzera se desiccant, catalyst carrier, fluorine removal agent, pressure swing adsorbent, special regeneration agent ye hydrogen peroxide, nezvimwewo. Alumina yakakamurwa inoshandiswa zvakanyanya se catalyst uye catalyst carrier.
Alumina inoshandiswa se desiccant, inonyanya kushandiswa mumidziyo yekuomesa mhepo yeindasitiri, michina yekuomesa mhepo ine simba rekushanda, kazhinji iri pasi pe0.8Mpa, iyo inoda kuti chiyero chealumina chakashandiswa chive nesimba rakanaka remuchina, kana simba remuchina rakaderera, zviri nyore kuigadzira upfu, musanganiswa weupfu nemvura uchavhara zvakananga pombi yemidziyo, saka, Chiratidzo chakakosha chealumina inoshandiswa se desiccant isimba, michina yekuomesa mhepo ine simba, kazhinji matangi maviri, matangi maviri anoshanda achichinjana, chaizvoizvo i adsorption saturation → analytic cycle process, desiccant inonyanya kudsorption mvura, asi mumamiriro ekushanda chaiwo, mhepo yekuomesa mhepo ine simba remhepo inobva kumhepo ine mafuta, ngura nezvimwe tsvina. Zvinhu izvi zvinokanganisa zvakananga hupenyu hwebasa re adsorbent yakashandiswa, nekuti activated alumina i porous adsorption material, natural adsorption polarity yemvura, oil adsorption yakanakawo, asi oil ichavhara zvakananga activated alumina adsorption pore, kuitira kuti kurasikirwa nehunhu hwe adsorption, ipapo Inenge ngura iri mumvura, yakabatana pamusoro pealumina yakakamurwa, Ichaita kuti alumina yakakamurwa irasikirwe zvakananga, saka mukushandisa alumina yakakamurwa se desiccant, edza kudzivirira kusangana nemafuta, ngura, alumina yakakamurwa se desiccant hupenyu hwese hwemakore 1 ~ 3, kushandiswa chaiko kuchave pakuisa gasi dova kuti usarudze kana uchida kutsiva alumina yakakamurwa. Tembiricha yekudzoreredza alumina yakakamurwa iri pakati pe180 ~ 350℃. Kazhinji, tembiricha ye alumina yakakamurwa inokwira kusvika 280℃ kwemaawa mana. Alumina yakakamurwa inoshandiswa semushonga wekurapa mvura, uye aluminium sulfate solution inoshandiswa semushonga wekugadzirisa. Kuwanda kwe aluminium sulfate regenerator mumhinduro ndeye 2 ~ 3%, alumina yakakamurwa mushure mekunyudzwa inoiswa mu aluminium sulfate solution, rasa mhinduro, sukurudza nemvura yakachena ka3 ~ 5. Mushure mekushandisa kwenguva refu, pamusoro pealumina yakakamurwa inova yero brown uye defluorination effect inodzikira, iyo inokonzerwa nekunyudzwa kwetsvina. Inogona kurapwa ne3% hydrochloric acid kamwe chete uye yozodzorerwa patsva nenzira iri pamusoro apa.
