Kunezinhlelo ezintathu zokujikeleza eziku-Industrial Units, kanye nezinkinga ezikalini zithambekele ezenzeka ezinhlelweni zokujikeleza ezihlukile, ezinjengesistimu yokujikeleza kwamanzi, uhlelo lokujikeleza kwamanzi, kanye nohlelo lokujikeleza lwamanzi, kanye nohlelo lokujikeleza lwamanzi, kanye nohlelo lokujikeleza lwamanzi kanye nohlelo lokujikeleza lwamanzi. Izinsiza zokujikeleza ezihlukile zidinga ukubambisana kwe-tacit ukufeza inhloso yomsebenzi ozinzile.
Ngakho-ke, kuyadingeka ukugcina uhlelo ngalunye phakathi kobubanzi obujwayelekile bokusebenza. Yize ukusebenza kwemishini ekhiqizwayo yasendlini ekhiqizwe ngaphambi kwezimboni zizinzile, uma ukulungiswa okudingekayo nokulungiswa kwenziwa isikhathi eside, kuzoholela ekutheni kube nezinkinga ezinkulu zezinkinga ezinkulu. Akuholelanga ngokuvinjelwa kwemishini, kepha futhi kuthinta nokugeleza kwamanzi kwemishini.
Inomthelela omkhulu ekusebenzeni okuphelele kwamayunithi wesandisi lezimboni, futhi anciphise impilo yonke yamayunithi efriji ezimboni. Ngakho-ke, ukugezakala kwesilinganiso ngesikhathi kubaluleke kakhulu kumayunithi efriji ezimboni.
1. Kungani isiqandisi sesisezingeni elifanele?
Izici eziphambili zokukala ohlelweni lwamanzi apholile kukhona usawoti we-calcium kanye nosawoti we-magnesium, futhi ukuhlukunyezwa kwawo kuncipha ngokwanda kokushisa; Lapho amanzi apholile exhumana ebusweni be-exchanger yokushisa, ukukala imali ebekiwe ebusweni be-exchanger yokushisa.
Kunezimo ezine zesiqandisi esithambekele:
(1) I-Crystallization of usawoti kusisombululo esiphezulu ngezakhi eziningi.
(2) Ukubekwa kwama-colloids we-organic nama-colloids amaminerali.
(3) ukubopha izinhlayiya eziqinile zezinto ezithile ezinamazinga ahlukene wokuhlakazeka.
. Enjenge-CA (HCO3) 2, CO3), CACO3, CA (OH) 2, i-CASO4, MGCO3, MG (OH) 2, njll. Okwesibili, ukugcwala ngosawoti okuncibilikisiwe emanzini kuyanda, kufinyelela izinga lokuphamba. Ukusabela kwamakhemikhali kwenzeka emanzini afudumele, noma ama-ion athile akha amanye ama-ion ancilhoble usawoti.
Kuma-usawoti athile ahlangabezana nalezi zimo ezingenhla, ama-buds okuqala aqala ukufakwa endaweni yensimbi, bese kancane kancane abe izinhlayiya. Inesakhiwo se-crystal noma e-amortal noma i-aggregates ukwakha amakristalu noma amaqoqo. Usawoti we-bicarbonate uyisici esikhulu esibangela ukukala emanzini apholile. Lokhu kungenxa yokuthi i-calbonate esindayo ye-calconate ilahlekelwa ukulinganisela ngesikhathi sokushisa futhi ibophele ibe yi-calcium carbonate, ikhabhoni diok diokway namanzi. I-calcium carbonate, ngakolunye uhlangothi, ayincibilikise kancane futhi ngaleyo ndlela idiphozithi emishini yokupholisa imishini. Khona manje:
Ca (HCO3) 2 = I-CACO3 ↓ + H2O + CO2 ↑.
Ukwakheka kwesilinganiso ebusweni be-heansic exchanger kuzokonakalisa imishini futhi kunciphise impilo yenkonzo yemishini; Okwesibili, izokuvimba ukudluliswa kokushisa kwe-exchanger yokushisa futhi kunciphise ukusebenza kahle.
2. Ukususwa kwesilinganiso esiqandisini
1. Ukuhlukaniswa kwezindlela zokwehla
Izindlela zokususa isilinganiselo ebusweni bezingashisi zokushisa zibandakanya ukwehla kwencwajana, ukwehla kwemishini, ukwehla kwamakhemikhali nokudabula ngokomzimba.
Ngezindlela ezahlukahlukene zokudla. Izindlela zokwehla ezibonakalayo kanye nezindlela zokulwa nokulwa nezinto ezilungile, kepha ngenxa yomgomo osebenzayo wezinsimbi ezijwayelekile ze-elekthronikhi, kukhona nezimo lapho umphumela ungekho okuhle, njengokuthi:
(1). Ukuqina kwamanzi kuyehlukahluka kuye ngezindawo.
(2). Ubulukhuni bamanzi beyunithi lushintsha ngesikhathi sokusebenza, futhi i-rain yemvula yokukhanya kwe-elektroniki ye-elektroniki ingakha uhlelo olufanelekile ngokwengeziwe ngokuya ngamasampula wamanzi athunyelwa ngumenzi, ukuze kuthi:
(3). Uma opharetha enganaki umsebenzi wokuqhakaza, ingaphezulu le-Exchanger Exchanger asazokwenziwa.
Indlela ye-Chemical Desaling ingabhekwa kuphela lapho umphumela wokufudukelwa kokushisa weyunithi umpofu futhi ukukala kunzima, kepha kuzothinta imishini, ngakho-ke kuyathinta imishini, ngakho-ke kuyadingeka ukuvikela ukulimala kwesendlalelo se-gallvanized futhi kuthinte impilo yenkonzo yemishini.
2. Indlela yokususa ye-Sludge
I-Sludge yakhiwa ikakhulukazi amaqembu ama-microbial anjengegciwane kanye ne-algae ehlakaza futhi akhiqize ngamanzi, ahlanganiswe nodaka, isihlabathi, uthuli, njll. Ukwenza i-Sludge ethambile. Kubangela ukugqwala emapayipi, kunciphisa ukusebenza kahle futhi kwandise ukumelana nokugeleza, ukunciphisa ukuhamba kwamanzi. Kunezindlela eziningi zokubhekana nazo. Ungangeza ubumbano ukwenza udaba lokugcina kumanzi okujikeleza kwamanzi lube izimbali ze-alum bese uhlala ezansi kwesigaxa, esingasuswa ngokukhishwa kwendle, okungasuswa ngokukhishwa kwendle; Ungangeza i-distrant ukwenza izinhlayiya ezimisiwe zihlakazeka emanzini ngaphandle kokucwila; Ukwakheka kwe-sludge kungacindezelwa ngokungeza ukugcwala oseceleni noma ngokungeza ezinye izidakamizwa ukunxenxa noma ukubulala ama-microorganisms.
3.
Ukugqwala kube ngenxa yemikhiqizo ye-sludge kanye nemikhiqizo yokugqwala enamathela ebusweni be-tube yokudlulisa ukushisa ukwakha ibhethri lokuhlushwa komoya-mpilo. Ngenxa yentuthuko yokugqwala, ukulimala kweshubhu lokuhanjiswa kokushisa kuzodala ukwehluleka okukhulu kweyunithi, futhi amandla apholile azokwehla. Iyunithi lingashabalalwa, okwenza abasebenzisi baphathe ukulahleka okukhulu kwezomnotho. Eqinisweni, ekusebenzeni kweyunithi, inqobo nje uma ikhwalithi yamanzi ilawulwa ngempumelelo, ukuphathwa kwekhwalithi yamanzi kuyaqiniswa, futhi ukwakheka kokungcola kuvinjelwe, umthelela wokugqwala ohlelweni lwamanzi weyunithi ungalawulwa kahle.
Lapho ukukhuphuka kwesikali kwenza kube nzima ukusebenzisa izindlela ezijwayelekile ukubhekana nazo, imishini yokudabula eyonakalisayo ingafakwa ukuze kufakwe izikali zokulwa nokusebenza, njengemishini yokudla ye-elekthronikhi, imishini yokudlidliza ye-magnetic vibration, njll.
Ngemuva kwesilinganiso, uthuli kanye ne-algae
Ukuvimbela ukukala nokuqandeka kwamanzi esiqandisi ku-evaporator ngesikhathi sokusebenza, kunezinye izinhlobo ezimbili zezinhlelo eziqandayo zamanzi: umjikelezo ovulekile nomjikelezo ovulekile kanye nomjikelezo ovaliwe. Ngokuvamile sisebenzisa umjikelezo ovaliwe. Ngoba yisifunda esivaliwe, ukuhwamuka nokuhlushwa ngeke kwenzeke. Ngasikhathi sinye, umkhathi udedi, uthuli, njll. Emanzini ngeke ahlanganiswe emanzini, futhi ukukala kwamanzi esiqandayo kuncane, ikakhulukazi kubhekisisa okubandayo kwamanzi esiqandisi. Amanzi ku-evaporator aqhaqhazela ngoba ukushisa okususwe esiqandisini lapho kuvela ku-evaporator kukhulu kunokuba kushise amanzi okuqaka esiqandisini, ukuze amazinga okushisa aqandayo angehla ngaphansi kwephuzu leqhwa kanye namanzi. Ama-opharetha kufanele anake amaphuzu alandelayo ngesikhathi sokusebenza:
1. Ukuthi izinga lokugeleza lingena ku-evaporator lihambisana nesilinganiso sokuhamba esikalwe senjini enkulu, ikakhulukazi uma ivolumu yamanzi lifaka iyunithi ngalinye lingalingani, noma ngabe ivolumu yamanzi liyaphikisana nomuntu oyedwa. Iqembu lomshini shunt punomenon. Njengamanje, abakhiqizi be-Bromine chiller basebenzisa kakhulu ukuguqulwa kwamanzi ukuze bahlulele ukuthi ngabe kukhona ukungeniswa kwamanzi. Ukukhethwa kokushintshwa kwamanzi okugeleza kwamanzi kumele kuhambisane nezinga lokugeleza okulinganiselwe. Amayunithi anemibandela angahlonyiswa ama-valves ashukumisayo ashukumisayo.
2 Lapho izinga lokushisa lamanzi esiqandisi liphansi kune + 4 ° C, umgcini uzoyeka ukugijima. Lapho opharetha eqala okokuqala ehlobo njalo ngonyaka, kufanele abheke ukuthi ukuvikelwa kwamazinga okushisa okuphansi kwemisebenzi yefriji kusebenza nokuthi inani lokubeka amazinga okushisa linembile.
3. Ngesikhathi sokusebenza kohlelo lokufaka umoya we-Bromine Chiller, uma impompo yamanzi iyeka ukugijima, injini enkulu kufanele imiswe ngokushesha. Uma izinga lokushisa lamanzi ku-evaporator lisalahla ngokushesha, kufanele kuthathwe izinyathelo, njengokuvala isiqandisi sokukhipha amanzi se-evaporator, ukuze amanzi okuhwamukayo ageleze futhi avikele amanzi ukuthi aqhamuke.
4. Lapho i-Bromine Chiller Unit iyeka ukugijima, kufanele kwenziwe ngokuya ngezinqubo zokusebenza. Okokuqala Misa injini eyinhloko, linda imizuzu engaphezu kweshumi, bese uvimba iphampu yamanzi esiqandisini.
