Nheyo yekusefa kwevhu re diatomaceous
Waini nezvinwiwa zvakaseferwa nevhu re diatomaceous zvine kunaka kwakafanana, hazvina chepfu, hazvina zvinhu zvakasungirirwa kana zvakamira, zvakajeka uye zvinoonekera, zvine kusefa kwakanyanya, zvinogara munzvimbo diki, zvakareruka, uye zviri nyore kufambisa. Zvinhu zvikuru zvinodzora inyaya yeganda, kumanikidzwa kweganda, dhayamita, chiyero chekuwedzera, uye simba rekushambidza musana.
Ukobvu hwe membrane yesefa hunowanzova 2-3mm, uye saizi yetsumbu yevhu re diatomaceous i1-10 μ M. Mushure mekusefa, gara uchishandisa mvura, mhepo yakamanikidzwa, kana zvese zviri zviviri pakusuka kumashure. Zvakanakira kusefa pasina masuo kushanda zvakanaka kwekurapa, mvura shoma yekusukurudza (isingasviki 1% yemvura yekugadzira), uye nzvimbo diki (isingasviki 10% yenzvimbo yakajairwa yesefa yejecha). Kana tichienzanisa nesefa yekare yekeke rekotoni, ine zvayakanakira zviri pachena: kuchengetedza simba re92%, kurasikirwa newaini ne90%, kuchengetedza mari yemidziyo ye2/3, uye kuderedza vashandi vekugadzira ne3/4. Saka chii chiri musimboti wekushandiswa kwayo?
Nheyo yekusefa kwevhu rediatomaceous ndeyekusefa mvura. Pasi pesimba rekumanikidzwa kwepombi, inopinda mukamuri rekuunganidzira kuburikidza ne pre coating. Zvidimbu nema polymers zvinobatwa mu pre coating, uye mvura yakacheneswa inopinda mukamuri rekuunganidzira yobuda mumudziyo kuburikidza nepakati. Sefa iyi ine firita, chidzitiro chekutsigira, uye furemu yekunze. Chinhu chimwe nechimwe chekusefa ichubhu ine maburi akaita se skeleton, yakaputirwa newaya yesimbi uye yakafukidzwa ne diatomaceous earth coating pamusoro. Chinhu chekusefa chakasungirirwa pa diaphragm, uye zvikamu zvepamusoro nepazasi zve diaphragm ikamuri remvura isina kucheneswa uye kamuri remvura rakacheneswa. Kutenderera kwese kwekusefa kwakakamurwa kuita matanho matatu: kuisa membrane, kusefa, uye kushambidza musana.
Mutengo wakaderera wekusefa kwevhu rediatomaceous: kushandiswa kwemvura: kushandiswa kwemvura yekugezesa kumashure i1/10 yejecha rekusefa; Kushandiswa kwesimba: Simba rose remuchina weA-1 rinodzoserwa rinongori 3/5 yesimba rose remuchina weimba yemuchina wejaivhi wesand cylinder; Chiyero: Panguva yekusefa, inofanira kuwedzerwa mukamuri yemuchina weA-1, ine chiyero che0.2kg pa square mita yenzvimbo yekusefa padanho rekusefa.
Munzira yekusefa yevhu rediatomaceous, ivhu rediatomaceous pacharo rine maburi madiki akawanda echisikigo, uye maburi asina kurongeka ari muchikamu chefirita akareba uye akapararira zvakanyanya muchikamu chose chekeke, izvo zvinogona kunyudza uye kugamuchira zvidimbu zvidiki, nokudaro zvichivandudza kunaka kwekusefa. Kusefa kune zvikamu zviviri: kuongorora nekunyudza. Pakushanda, ivhu rediatomaceous rakakamurwa kuita pre coating uye chidimbu chefirita chinonyudza pajira rekusefa kunze kwesefa, zvichigadzira chidimbu chekeke refirita chisingadzvanyike chine maburi madiki asingaverengeki akaomarara uye anopindirana. Munguva yekusefa, tsvina huru mufirita inobatwa pamusoro pekunze kwechikamu chekeke refirita nekuda kwekusakwanisa kupfuura nemaburi madiki efirita, ayo anonzi maitiro ekuongorora. Zvidimbu zvidiki zvinopinda muchikamu chekeke refirita uye zvinonyudzwa uye zvinobatwa mumaburi akakombama uye akaomarara, ayo anonzi maitiro ekunyefa. Kuti uwane mhinduro yakajeka inopenya. Kana kumanikidzwa kwekusefa kwesefa kuchiwedzera, zvinoratidza kuti mamwe maburi efirita muchikamu chefirita akavharwa. Panguva ino, jira idzva rekusefa rinoumbwa nekuwedzera ivhu rediatomaceous kumuchina wekusefa kuti urambe uchisefa. Kana maburi mazhinji ari mujira rekeke rekusefa avharwa uye mwero wekusefa waderera, bvisa keke rekusefa, pukuta jira idzva rekeke rekusefa, wozosefa. Kana uchitarisa kusefa kwemakeke ekusefa akakamurwa kuita jira rakaiswa nejira rakaiswa nejira rakaiswa nejira, zvinogona kuonekwa kuti tsvina yakawanda inosefa nekusefa uye inovharirwa kunze kwemaburi ekusefa, netsvina shoma dzakanyungudutswa mukati memaburi.
