Iyini Ithangi Lokugcina Udaka? Idizayini, Izinto Zokwakha kanye Nendlela Engcono Yokwenza
Ithangi lokugcina udaka — elibizwa nangokuthi ithangi lokubamba udaka — iyisitsha esigcina udaka lwamanzi angcolile (ngokuvamile 2–8% okuqinile) phakathi kwezigaba zokujiyisa, ukugaya, ukukhipha amanzi kanye nokulahla. Ezitshalweni zanamuhla ngokuvamile iyithangi lensimbi ehlanganiswe nengilazi (GFS) noma ithangi lensimbi elimbondwayo elinama-mixer, izembozo, futhi lapho kudingeka, ukufudumeza.
Udaka luyinto egqwala kakhulu futhi enamathela kakhulu esitshalweni sokuhlanza: luqoqa i-H2S, ama-asidi e-organic nama-polymer kuyilapho luzinamathelisa kancane kancane kunoma iyiphi indawo emahhadlahhadla. Ithangi elimelana nakho kokubili amakhemikhali nokunqwabelana linquma ukuthi ukuphathwa kodaka kuyinto ejwayelekile noma iphupho lokulungisa.
1. Iyini Umsebenzi Wethangi Lokugcina Udaka Esitshalweni Sokuhlanza?
Isikhala phakathi kwezigaba zokucubungula: Udaka lukhiqizwa ngokuqhubekayo kodwa luyiswa amanzi noma luthuthwe ngamaqembu. Ithangi lokugcina lihlukanisa izinhlelo zokujiyisa, zokugaya kanye nezokukhipha amanzi, libambe izinsuku zokukhiqiza ngaphandle kokuwohloka.
Umkhumbi wokulungisa nokuhlanganisa: Ifakwe imishini yokuxuba ehamba kancane, ithangi lihlanganisa udaka oluyinhloko nolwesibili, lifake i-polymer, futhi ligcine izinto eziqinile zintanta ukuze ukukhipha amanzi okulandelayo kuthole ukudla okufanayo.
Inketho yokuvala umoya: Udaka olungalashwa luyaqhubeka nokubila, lukhiphe i-H2S enuka kabi futhi egqwala. Amathangi e-GFS avaliwe anezembozo ezivala umoya abamba lokhu kukhishwa futhi avikele imiphakathi ezungezile kanye nensimbi.
2. Kungani Udaka Ludinga Into Yokwakha Yezinga Eliphezulu
Ukuvikelwa kokugqwala ezingxenyeni zombili: Udaka olubilayo lube i-asidi; ukuzinziswa ngomcako kuphusha i-pH ibe yi-alkaline. I-enamel ye-GFS, ehlanganiswe nensimbi ku-820–930°C, ayisebenzi ku-pH 1–14, lapho izinto zensimbi ezimboziwe zixebuka futhi ukhonkolo wonakale.
Ezomnotho zokungabambeki kwengqimba: Ngobuningi bokuphansi kwe-surface ngaphansi kwe-Ra 0.8 µm, i-enamel ebushelelezi njengengilazi ivimbela i-sludge ukuthi ingatholi izindawo ezidingekayo zokubambelela. Ukuncipha kokunqwabelana kusho umthamo owusizo owengeziwe, amandla aphansi okuxuba kanye nokuncipha kwezikhathi zokuvala ukuze kuhlanzwe.
Ukufakwa okusheshayo, okuhlukanisekayo: Izitshalo zingeza umthamo wokugcina udaka ngaphandle kokumisa imisebenzi — amaphaneli aboshwe ngamabhawodi ayamiswa ngokukhuphula ngamandla kagesi emasontweni, futhi amathangi angandiswa noma athuthelwe kwenye indawo njengoba isu lodaka lishintsha. Yonke imithungo iqinisekiswa ngokuhlolwa kweholide ye-DC engu-1500V ngokwe-AWWA D103 ne-ISO 28765.
Ithebula Lokuqhathanisa: Izinto Zethangi Lokugcina Udaka
Upharamitha Wokuhlola | Ithangi Lodaka Lwe-GFS | Ithangi Lensimbi Elihlanganiswe Nge-Epoxy | Ithangi Likakhonkolo |
Resistance to H2S and pH swings | Kuhle kakhulu — i-enamel engasebenzi, i-pH 1–14 | Okumaphakathi — ukumboza kuhlaselwa ama-asidi | Okumaphakathi — kunembobo, kugqwala insimbi yokuqinisa |
Ukunamathela kwe-sludge nokuhlanzwa | Kuncane kakhulu — Ra < 0.8 µm ingilazi ebushelelezi | Phezulu — izindawo ezinobuso obunamagquma | Phezulu — amagquma, imifantu ibamba ukunqwabelana |
Ukuhlanganiswa kwekhava engangeni moya | Amakhava akhiwe ngobunjiniyela aboshwa ngamabhawodi | Kungenzeka kodwa kuzwela emthungweni | Kunzima ukuvala |
Izindleko zokunakekela zeminyaka engu-30 | Cishe akukho | Ukuphinda kufakwe ungqimba njalo eminyakeni emi-5–8 | Ukulungiswa okuqhubekayo kwemifantu |
Imibuzo Ejwayelekile (FAQ)
UMBUZO 1: Liyini ithangi lokugcina udaka?
Ithangi lokugcina udaka liphethe udaka lwendle phakathi kokujiyisa, ukugaya, ukukhipha amanzi kanye nokulahla. Izinhlobo ze-Glass-fused-to-steel zimelana nokugqwala kwe-H2S ku-pH 1–14 futhi zine-surface engaphansi kwe-Ra 0.8 µm evimbela udaka ukuthi lunamathele ezindongeni.
Q2: Kungani amathangi odaka agqwala ngokushesha kunamanye amathangi endle?
Udaka luqoqa ama-acid aphilayo futhi lukhiqiza igesi ye-H2S, eguquka ibe i-sulfuric acid ezindongeni nasezindaweni ezingaphezulu. Izinto ezingasebenzi njenge-fused glass enamel noma ama-alloy aphezulu kuphela ezibekezelela lesi simo iminyaka engaphezu kwengu-30.
Q3: Ingabe ithangi lokugcina udaka lingamboziwa ukuze kulawuleke iphunga?
Yebo. Izembozo eziboshwe ngokuqinile, ama-vent kanye nama-odor scrubber interfaces akhelwe kumathangi odaka e-GFS, aqukethe i-H2S kanye nama-volatile organics kuyilapho evumela ukungena kwama-mixer nama-level-instrument.
Umbuzo 4: Ulinganisa kanjani ithangi lokugcina udaka?
Umthamo oyisisekelo ususelwa ezingeni lokukhiqiza i-sludge uma liphindwe ngezinsuku ezidingekayo zokugcina (ngokuvamile izinsuku ezingama-10–30), kulungiswe ngokusebenza kokujiya. Amathangi e-GFS amamojula asuka ku-100 m³ kuya ku-32,000 m³ avumela ukunwetshwa kamuva njengoba imithwalo ikhula.
