Nekukura kwehuwandu hwevanhu uye kusimukira kwehupfumi, zviwanikwa zvemvura yakachena zviripo zviri kudzikira zuva nezuva.Kugadzirisa dambudziko iri, midziyo yekuchenesa mvura yegungwa yakashandiswa zvakanyanya kushandura mvura yegungwa kuita mvura yakachena inogona kushandiswa.Ichi chinyorwa chichasuma nzira, kushanda musimboti uye process flow chart yemvura yegungwa desalination.
1.Nzira yekuchenesa mvura yegungwa
Parizvino, kuchenesa mvura yegungwa kunonyanya kutora nzira nhatu dzinotevera:
1.Distillation nzira:
Nekupisa mvura yegungwa kuti ishanduke kuita mhute yemvura, uye woitonhodza kuburikidza necondenser kuishandura kuita mvura yakachena.Distillation ndiyo yakajairika nzira yekuchenesa mvura yegungwa, asi mari yemidziyo yayo yakakwira uye kushandiswa kwesimba kwakanyanya.
2.Reverse osmosis nzira:
Mvura yegungwa inosefa kuburikidza nekamwe-permeable membrane (reverse osmosis membrane).Iyo membrane ine diki pore size uye chete mamorekuru emvura anogona kupfuura, saka mvura yakachena inogona kuparadzaniswa.Iyo nzira ine yakaderera kushandiswa kwesimba uye nyore nzira, uye inoshandiswa zvakanyanya mumunda wemvura yegungwa desalination.Toption Machinery Seawater Desalination Equipments inoshandiswawo nenzira iyi.
3.Electrodialysis:
Shandisa maitiro emaion anochajiswa kufamba mumunda wemagetsi kuti uparadzane.Ioni dzinopfuura nepakati peiyoni yekuchinjana membrane kuita mativi ese emushonga wedilute uye iyo yakanyungudutswa mhinduro.Iwooni, mapurotoni uye maerekitironi mumushonga wedilute zvinopatsanurwa zvine simba kuita maion matsva ekuchinjana., kuitira kuti uone kuparadzaniswa kwemvura yakachena, asi kushandiswa kwesimba kwakakwirira, uye kune zvishoma zvikumbiro panguva ino.
2.Kushanda nheyo yemvura yegungwa desalination midziyo
Kutora reverse osmosis semuenzaniso, maitiro ekushanda emidziyo yekubvisa mvura yegungwa ndeaya anotevera:
1.Seawater pretreatment: kuderedza zvimedu, tsvina nezvimwe zvinhu mumvura yegungwa kuburikidza nekugadzirisa uye kusefa.
2.Kugadzirisa hutano hwemvura: gadzirisa pH kukosha, kuoma, salinity, nezvimwewo zvemvura kuti zvive zvakakodzera reverse osmosis.
3.Reverse osmosis: Sefa mvura yegungwa yakateyiwa uye yakagadziridzwa kuburikidza nereverse osmosis membrane kuti iparadzanise mvura yakachena.
4.Wastewater discharge: mvura yakachena nemvura yakasvibiswa inoparadzaniswa, uye mvura yakasvibiswa inorapwa uye inobudiswa.
3.Process flow chart yemvura yegungwa desalination equipment
Iyo nzira yekuyerera chati yemvura yegungwa desalination zvishandiso ndeiyi inotevera:
Kugadziriswa kwemvura yegungwa → mutemo wemhando yemvura → reverse osmosis → kuyerera kwemvura yetsvina
Muchidimbu, desalination yemvura yegungwa inzira inokosha yekugadzirisa dambudziko rekushaya mvura yakachena, uye kushandiswa kwayo kuri kuwedzera kuwedzera.Nzira dzakasiyana dzekubvisa salination dzinoda tekinoroji nemidziyo, asi misimboti yekushanda yakafanana.Mune ramangwana, michina yekuchenesa mvura yegungwa ichavandudzwa nekuvandudzwa mune tekinoroji nemidziyo yekupa vanhu mhinduro dzakavimbika uye dzinoshanda.
