Nanofiltration ya maji machafu ya juu --- usanidi unaohusiana na kifaa cha kutenganisha chumvi ya osmosis
Nanofiltration ya maji machafu ya juu ---- usanidi unaohusiana na kifaa cha kutenganisha chumvi ya osmosis
The produced water flow is 77m3/h, the design recovery rate is 70%, the design flux is 16.5LMH, and the sulfate removal rate is ≥95%. The number of membranes required for calculation is 138, and the membrane shell is 6-core, with a total of 23 membrane shells.
Kwa kuwa COD yenye ushawishi ni kuhusu 100mg / L, ili kuhakikisha kiwango cha kutosha cha mtiririko wa msalaba kwenye upande wa maji uliojilimbikizia wa utando, muundo wa hatua tatu unapitishwa, na pampu ya nyongeza ya hatua imewekwa kusawazisha flux ya hatua na uzalishaji wa maji. Uwiano wa mpangilio wa ganda la utando ni 12: 7: 4, na shinikizo la kuongeza pampu ya nyongeza ya hatua ya kati inabadilishwa kuwa 5bar. Matokeo ya hesabu yanaonyeshwa katika takwimu hapa chini. Inlet ya maji ya ganda moja la utando inaweza kuhakikishiwa kuwa juu ya 9m3 / h.
Ripoti ya ubora wa maji
1. Security filter: FRP horizontal membrane shell type, external pressure filtering. Single filter processing capacity 20m3/h, 6 filters are selected, each filter inlet and outlet is equipped with manual butterfly valve to ensure non-stop filter element replacement. 40-inch filter element total length L = 1120mm, end and tail cover diameter Φ154±1mm.
2. Pampu ya maji: Pampu ya shinikizo la juu Q = 110m3 / h, H = 190m, N = 90kW; pampu ya nyongeza ya hatua mbili Q = 68m3 / h, H = 50m, N = 18.5kW; pampu ya nyongeza ya hatua tatu Q = 45m3 / h, H = 50m, N = 15kW; Vifaa vya pampu ya maji ni SS2205
3. Membrane housing: According to the operating pressure of each section, the first, second and third section membrane shells are respectively selected from the 8040 series 300, 450 and 450psi membrane shells. The outer diameter of the membrane shell is φ244mm, and the inner diameter is φ203mm. When designing the device, the first section is at the bottom of the membrane frame and the third section is at the top of the membrane frame. The three sections of concentrated water pipeline are higher than the installation height of the membrane shell at the highest point of the skid frame.
4. Vyombo: Viwango vya shinikizo vimewekwa kwenye inlet na plagi ya kichujio cha usalama, kila sehemu ya maji ya maji na maji yaliyojilimbikizia, na bomba la uzalishaji wa maji; kila sehemu ya inlet ya maji na maji yaliyojilimbikizia, Msambazaji wa shinikizo imewekwa kwenye bomba la uzalishaji wa maji na bomba la uzalishaji wa maji lililojilimbikizia; kichujio cha usalama kimesakinishwa na kisambazaji cha shinikizo tofauti; Inlet na plagi ya pampu ya shinikizo la juu imewekwa kwa mtiririko huo na swichi ya shinikizo la chini na swichi ya shinikizo la juu; bomba la uzalishaji wa maji na bomba la maji lililojilimbikizia limewekwa na mita ya mtiririko wa mbali; Sehemu ya kwanza na ya pili ya uzalishaji wa maji imewekwa na mita ya mtiririko wa rotor;
5. Fremu: Chini imetengenezwa kwa chuma cha kituo cha 12#, msaada wa wima na msaada wa usawa wa bomba la utando hufanywa na mirija ya mraba ya 8#, na zingine zimetengenezwa kwa mirija ya mraba ya 5#.
6. valve ya moja kwa moja: iliyo na valve ya nyumatiki kwa kutokwa kwa uzalishaji wa maji; valve ya nyumatiki kwa kutokwa kwa maji ya kujilimbikizia; valve ya umeme kwa inlet ya maji; valve ya umeme kwa inlet ya maji ya flushing;
