Izithasiselo zikakhonkolo ezingasindi | Ama-ejenti Akhipha Amagwebu Asebenza Kakhulu Wokhonkolo Weselula
Iyini i-foam generator?
Umshini wokugcwalisa amagwebu, eyaziwa nangokuthi i-foam generator, iwuhlobo lwemishini yegwebu elenza i-ejenti ekhihlizayo ifinyelele ekuhlanganiseni okuthile kwesisombululo esinamanzi. I-ejenti enegwebu ngokwayo ayikwazi ukuphenduka igwebu ngokuzenzakalelayo, kufanele kudlule isenzo somshini womshini okhipha amagwebu ukuze ube igwebu.
Uyini umgomo we-generator ye-foam?
Kungakhathaliseki ukuthi i-generator ye-foam, umgomo oyisisekelo wokukhihliza amagwebu ukwethula umoya ekhambi le-ejenti eligwebulile. Izinhlobo ezahlukene zezinguquko zihlukile endleleni yokwethula igesi, ngakho umphumela nawo uhlukile.
Kunezici ezimbili ezidingekayo zokwakheka kwegwebu, enye isixazululo se-ejenti egwebuzelayo, kanti enye ingumoya, kokubili kudingekile. Ngaphandle kwesixazululo se-ejenti efuthayo, ifilimu ewuketshezi ezungeze igesi ibingeke yakheke futhi bekungeke kube namabhamuza. Futhi ngaphandle kwegesi, Isixazululo somenzeli ogwebuyo sisodwa asikwazi ukwakha amabhamuza.
Kuhlelo lokwakheka kwebhamuza, isixazululo se-ejenti evuthelayo yi-dispersion medium, igesi yisigaba esihlakazekile, futhi igesi ihlakazeka oketshezini ukwenza amagwebu, bese kuthi amagwebu amaningi akhe igwebu. Ngaphezu kwesici esibalulekile sokusebenza kwe-ejenti yokuphefumula, ukwethulwa kwegesi esixazululweni se-ejenti efuthayo kungenye into ebalulekile. Umgomo wejeneretha yegwebu ukwethula igesi oketshezini, leyo, ijeneretha yegwebu isebenzisa indlela ethile yokwethula igesi oketshezini. Imishini ehlukene yokukhipha amagwebu inezindlela ezihlukene zokwethula igesi. Ngenjwayelo, kunezindlela eziningana zokwethula igesi emshinini okhipha amagwebu:
(1) Ama-blade ajikelezayo kancane ethula igesi
Lena indlela yokwethula ngokuqondile igesi odakeni (noma udaka lukakhonkolo) exutshwe ne-ejenti yokugwedla usimende. Lapho i-mixer blade iphusha i-slurry, umoya ungena odakeni ngama-mixer blades. Ngaphezu kwalokho, umthamo omkhulu womoya ugoqwe ku-slurry lapho i-slurry iphendulwa, futhi ingxenye yomoya ilethwa odakeni ngosimende neqoqo. Isamba salokhu okuthathu yisamba esiphelele somoya ongena odaka. Phakathi kwazo, umoya olethwe odaka ngensingo enyakazayo kanye nomoya osongwe ngensingo ephendula udaka luhlala emzimbeni omkhulu.
Ngemva kokuba umoya ungena odakeni, uketshezi oluqukethe isisetshenziswa esikhipha amagwebu sizungeza umoya, ukwakha ifilimu ye-electron ephindwe kabili ye-liquid kusixhumi esibonakalayo phakathi komoya noketshezi, futhi ekugcineni yenze amabhamuza ku-slurry ngesimo se-air-in-liquid.
Ngenxa yejubane lokujikeleza elihamba kancane lama-blades kanye negesi encane eyethulwe ngale ndlela, inani lamabhamuza akhiqizwayo lincane, umphumela wegwebu awumuhle, nokusebenza kahle kuphansi.
(2) Ama-blade ajikelezayo anesivinini esikhulu angenisa igesi
Lena indlela yokwethula igesi esixazululweni se-ejenti efuthayo ngokuthembela kuma-blade ajikelezayo anesivinini esikhulu.. Ukwethulwa kwegesi ikakhulukazi kuncike emandleni ama-blade ajikelezayo. Ama-blades alolu hlobo ngokuvamile adinga ukujikeleza kwesivinini esikhulu, isivinini kufanele sibe > 700 rpm, ngokuvamile phakathi 700 futhi 1400 rpm, futhi isivinini se-peripheral yesiphetho se-impeller kufanele sibe> 20 m/s ukuze uthole imiphumela egculisayo. Ijubane elithile eliphakeme lingadalula i-impeller oketshezini, ukuxhumana nomoya, futhi wethule umoya. Uma ijubane liphansi kakhulu, i-impeller ngeke ivezwe oketshezini, futhi inani lomoya wokopha lizoba phansi kakhulu. Ijubane elifanele kufanele libe ngaphansi kune-impeller evezwayo lapho uketshezi lujikeleza.
Umgomo oyisisekelo we-impeller bleed air umi kanje:
Lapho i-impeller ijikeleza ngesivinini esikhulu, ishayela isixazululo se-ejenti ekhihliza usimende kusilinda esigwebulile ukuze sijikeleze, ukwakha ukujikeleza okujikelezayo futhi kukhiqize i-vortex enkulu. Ngalesi sikhathi, izinhlayiya zezigaba ezimbili zegesi-uketshezi olutholakala kusixhumi esibonakalayo se-gas-liquid phezulu kwesisombululo se-ejenti ephephethayo zizoziphelezela phansi futhi zehlele phansi kwe-vortex ngendlela esheshayo yokuvunguza., ukwakha indawo egelezayo eneziyaluyalu ku 2.5-5 cm we-impeller edge. Kule ndawo, izinhlayiya ze-gas-liquid zezigaba ezimbili zingaphansi kokugunda okuqinile nomthelela we-impeller, futhi zihlakazwa ekuhlelweni okuhle, eqaphela ngokushesha ukuxubana kwe-gas-liquid, yenza igesi ihlakazeke ngokufanayo oketshezini, futhi uyaqaphela igesi Yethula. Ukusebenza kwayo kahle kwesingeniso kuhlobene nezici ezihlukahlukene zobuchwepheshe njengejubane, ububanzi be-impeller, ibanga phakathi kwe-impeller kanye neshubhu eligwebuzelayo, kanye nokuma kwama-impeller blades. Ayinqunywa isivinini esisodwa. Ama-impellers anesivinini esikhulu anemiphumela yokungenisa umoya, kodwa ukusebenza kahle, umphumela, kanye nokusetshenziswa kwamandla kuhlukile.
(3) Ukusetshenziswa kwengcindezi ukwethula igesi.
Lokhu okwamanje kuyindlela evame ukusetshenziswa kakhulu ethuthukisiwe yogwebu olufakwe emoyeni ekhaya naphesheya. Futhi kuyindlela yesayensi yokungenisa umoya. Iwumgogodla wobuchwepheshe be-foam ukhonkolo we-foam high-pressure kanye ne-medium-pressure foam generator technology.
Izindlela ezimbili ezishiwo ngenhla zihamba kancane futhi azilingani, futhi ububanzi bebhamuza bukhulu, ikakhulukazi ububanzi bebhamuza alikwazi ukulawulwa. Kuncike ngokuphelele ekungahleliwe komshini okhipha amagwebu, futhi ayikwazi ukuqinisekisa ububanzi bebhamuza elincane kanye negwebu elifanayo. Izinkomba zobuchwepheshe ezibucayi kakhulu. Ngesikhathi esifanayo, inani lokukhihliza amagwebu kunzima ukulilawula.
Ukuze uxazulule ngempumelelo izinkinga ezingenhla, indlela yokukhihliza amagwebu efakwe ngaphansi kwengcindezi yaba khona. Kungakhathaliseki ukuthi ivolumu egcwele amagwebu, isivinini esikhihliza amagwebu, noma ububanzi begwebu kanye nokufana kwegwebu, njll., sebedlulele kwelinye izinga futhi benze inqubekelaphambili enkulu kwezobuchwepheshe. Umgomo wayo oyinhloko ukusebenzisa imishini ehlukahlukene engakwazi ukukhiqiza umfutho womoya ukuze ucindezele umoya ungene esigabeni esiwuketshezi ukuze kuzuzwe ukuxutshwa okufanayo kwezigaba ezimbili.. Ngaphansi kwengcindezi evamile, kunzima ukuthi umoya ungene oketshezini, kodwa ngaphansi kwengcindezi ethile, kuba lula. Lo mfutho womoya awugcini nje ngokucindezela igesi oketshezini, kodwa futhi ucindezela uketshezi kugesi. Empeleni, kanyekanye isebenzisa ingcindezi. Ngale ndlela, ukuxutshwa kwezigaba ezimbili kuzoshesha, ngempumelelo, umfaniswano, futhi ube namabhamuza amahle, ehlangabezana nezidingo ezifanele zobuchwepheshe zegwebu.
Kunezinhlobo ezimbili eziyinhloko zemishini yokucindezela esetshenziswa ezweni lakithi, enye iyi-compressor yomoya kanti enye iyi- blower. I-compressor yomoya ikhiqiza umfutho ophezulu, futhi i-blower ikhiqiza umfutho ophansi ophakathi. Ngakho-ke, umphumela we-foaming we-compressor yomoya ungcono, futhi umphumela okhihliza amagwebu we-blower uba mubi kancane. Ukwenza amagwebu nge-compressor yomoya kubizwa ngokuthi umshini okhipha amagwebu onengcindezi ephezulu, futhi ukukhihliza amagwebu nge-blower kubizwa ngokuthi i-foam generator ye-foam ephakathi nendawo. Ikhwalithi enegwebu ye-compressor yomoya ilawula ngokuyinhloko ingcindezi nokugudluzwa kwayo, kuyilapho ukucweba kwesiphephetha ngokuyinhloko kulawula umfutho wayo womoya kanye nomthamo womoya.
Ngenxa yomphumela omuhle we-foaming we-air compression mechanism, Imishini eminingi ekhipha amagwebu ezweni lakithi isebenzisa ama-compressor emoyeni. Ukubhula amagwebu nakho kunezinhlelo zokusebenza eziningi ezweni lami, kodwa uma kuqhathaniswa nogwebu olunomfutho ophezulu, le ndlela yokukhihliza amagwebu iseyivelakancane. Igwebu elikhiqizwe wugwebu lomfutho ophezulu wengcindezi linezinga eliphansi lokumunca amanzi, ububanzi be-bubble buncane, minyene futhi iyunifomu, futhi izinga liphezulu. Igwebu elikhiqizwa i-blast foaming linobubanzi obuthe ukukhudlwana, futhi ikhwalithi iyonke ayilungile njengokugcwala amagwebu ngomfutho ophezulu.
(4) Indiza enomfutho ophezulu wethula igesi
Lena indlela yokukhihliza amagwebu esike yazanywa eminyakeni yamuva kodwa ayisasetshenziswa kakhulu. Isimiso esiyisisekelo siwukusebenzisa amandla anamandla okuhlakazeka akhiqizwe indiza ukuze kuzuzwe ukuthintana kwendawo enkulu ngokushesha phakathi kwesigaba segesi kanye nesigaba soketshezi., ukuze kokubili kuhlanganiswe ngokulinganayo, futhi uketshezi luyaboshelwa ukwenza igwebu. Le ndlela ayibonisi izinzuzo ezingaphezu kokukhipha amagwebu komoya wokucindezela okuphezulu, futhi idinga ukuhlolwa nokuthuthukiswa okwengeziwe.
I-Cie-China.org ingumhlinzeki oholayo wezithasiselo zikakhonkolo wegwebu ohlinzeka nge-ejenti yokugwedla ukhonkolo, superplasticizer,isithuthukisi samandla kakhonkolo wegwebu kukhonkolo ongasindi, Amabhulokhi e-CLC. Uma ufuna ijeneretha yegwebu, sicela ukhululeke Xhumana nathi.
