Dope remarara ndeimwe yenzvimbo huru dzekusvibisa muindasitiri yemafuta negasi. Kuitira kudzivirira kusvibiswa kwezvakatipoteredza kunokonzerwa nemarara ekuchera madhaka, inofanirwa kurapwa. Maererano nemaitiro akasiyana-siyana ekurapa uye kubuda, kune nzira dzakawanda dzekurapa kwemarara emarara pamba uye kunze kwenyika. Mushonga wesolidification ndiyo imwe yenzira dzinoshandiswa zvikuru, kunyanya dzakakodzera marara emarara asina kukodzera kurima ivhu.
1. Kubatanidzwa kwemarara ekuchera madhaka
Solidification kurapwa kuisa chikamu chakaringana cheanorapa mugomba remarara remavhu, kusanganisa zvakaenzanirana maererano nezvimwe zvinodiwa zvehunyanzvi, uye kushandura zvinokuvadza kuita simbi isingasvibise kuburikidza nekuchinja kwemuviri nemakemikari kwenguva yakati.
Nzira yekuverenga yekuomesa madhaka: huwandu hwezvikamu zvakasimba mushure mekupatsanurwa kwemvura yakasimba-yesimende slurry uye desander, desilter, dope remarara rinobudiswa kubva mucentrifuge, uye grit yakabudiswa kubva muguri retangi.
2. MTC teknolojia
Kusandurwa kwedhaka kuita samende samende, yakadimburirwa tekinoroji yeMTC (Mud To Cement), ndiyo inotungamira pasi rose tekinoroji yekugadzira simende. Slag MTC inoreva kuwedzera mvura-yakadzimwa blast furnace slag, activator, dispersant uye mamwe maajenti ekurapa muslurry kushandura slurry kuita simende slurry. Iyi tekinoroji inodzikisa mutengo wekurapa wemarara slurry uye zvakare inoderedza mutengo we simende.
3. Kemikari yakagadziridzwa yakasimba-yemvura kuparadzaniswa
Iyo kemikari yakagadziridzwa yakasimba-mvura yekuparadzanisa maitiro inotanga kuita kemikari destabilization uye flocculation kurapwa padhaka rekuchera, inosimbisa iyo mechaniki yakasimba-mvura yekuparadzanisa kugona, uye inoshandura zvinokuvadza zviri mudhaka remarara kuita zvinhu zvisingakuvadzi kana zvisingakuvadzi kana kuderedza chiyero chayo. panguva yemakemikari destabilization uye flocculation kurapwa. Zvadaro, dhaka risina kugadzikana uye risina kurongeka rinopombwa mumhando ye-turbo-drilling fluid centrifuge. Iyo inotenderera inotenderera mumvura yekuchera centrifuge uye kubvongodza kunokonzerwa nedhiramu inotenderera yakabatana inoburitsa yakazara dynamic mhedzisiro, ine simba rakasimba pane semi-static sedimentation mu centrifuge, uye inoziva kuparadzaniswa kwakasimba-mvura, kuitira kuti mvura yemahara. pakati pe floc particles uye chikamu che intermolecular mvura inoparadzaniswa ne centrifugation. Mushure mekuparadzana kwakasimba-mvura, huwandu hwezvinosvibisa (sludge) hunoderedzwa, huwandu hunoderedzwa zvakanyanya, uye mari yekurapa isingakuvadzi yakapetwa kaviri.
4. Kuraswa kwemarara kubva pakuchera kumahombekombe
(1) Kugadziriswa kwedhaka rine mvura
(2) Kurapwa kwedhaka rine mafuta
Nzira yekuyerera kwedhaka isiri-kumhara kurapwa
(1) Chikamu chekuunganidza. Madhaka ekuchera tsvina anopinda muscrew conveyor kuburikidza nemidziyo yakasimba yekudzora, uye mvura inowedzerwa kuti iwedzere nekusanganisa.
(2) Solid-liquid separation unit. Kuti uderedze huwandu hwemvura uye kusvibiswa kwekakeke yedhaka, zvinodikanwa kuwedzera vamiririri vekurapa uye kudzokorodza uye kugeza.
(3) Wastewater treatment unit. Izvo zviri mukati mezvimedu zvakamiswa mumvura zvakaparadzaniswa ne centrifugation zvakakwirira. Iyo yakaturikwa yakaoma mumvura inobviswa kuburikidza nemhepo flotation sedimentation uye filtration system kuti ideredze zviri mukati meiyo organic zvinhu mumvura yetsvina, uye wozopinda reverse osmosis system yekufungisisa kurapwa.
