Deaerator - ntoni na? Iintlobo yesixhobo, isimiso ukusebenza

Boilers zidla ezenziwe ngentsimbi. Watyhutyha therethrough yamanzi Isakhiwo oksijini carbon dioxide. Zombini ezi zinto kuba phezu izakhiwo ezibengezelayo kwibhoyila nefuthe elibi kakhulu. bahlale kunye kwezi gesi ziye ekugqibeleni kukhokelela ukurusa yayo. deaerator - ukuze ukulungisa le meko kwaye kunaba ubomi kwezixhobo, ufakelo ezizodwa zifakiwe kwisikimu kwibhoyila thermal. Yintoni na? Kule kwaye ndiya kuthetha kamva kweli nqaku.

definition

Deaerator wabiza izixhobo ezizodwa eyenzelwe ukususa ioksijini ukususela kwiinkqubo njengesipholisi zokufudumeza ngokufudumeza up phenyane lokugqibela. Ngenxa yoko, ukongeza kumsebenzi zokucoca, olu hlobo izixhobo zisebenze njengoko ubushushu. Kucwangciso efanayo ingasetyenziselwa deaeration kunye nonyango ukufudumeza nje kokutya namanzi kwenza-up.

Iimpawu design

Le lula ekhoyo yoyilo - nantso into eyahlula de-empompeni. Yintoni na Sofunyanwa. Ngoku makhe sibone indlela amalungiselelo esi sixhobo. It imele itanki deaerator kwibhoyila (BDA) kunye ekhwele phezu kwaso ikholam nkqo (KDA) zixhonywe lisekela. An into olongezelelweyo olu hlobo nezixhobo zomsebenzi yinkqubo ngamanzi elikhusela ukusuka overpressure. Ikholam yi welding, ukuba itanki ngaphandle esisangqa - ngqo.

Kwi itanki deaerator tye bakhwela owongozelelweyo eKFC ukuqhagamshela imigca omxhesho ukubhobhoza eliphakathi. olubi Ezantsi-imvelaphi inyuselwa khona. Enye elementi uyilo ilungiselelwe ukuqokelelwa itanki yokuqokelela amanzi degassed. Le ibekwe phantsi emazantsi BDA.

inkqubo ngamanzi izixhobo ezifana deaerator, umzobo oboniswe apha ngezantsi, ngokokuqhelekileyo kuba lock ezimbini hydraulic. Omnye Ikhusela isixhobo nakweyiphi uxinzelelo ngokugqithiseleyo, kwaye eyesibini - eyingozi. Kwakhona ekwakhiweni kwenkqubo ngamanzi ubandakanya deaerator itanki ukwanda. Ukuba ngumphunga izakondliwa deaerator ukuya njengesipholisi okhethekileyo ukuba njengesilinda tye.

design column

Ikholam liqokobhe zezindlu kunye ezantsi imilo okweqanda. Njengoko ngaphakathi etankini, kuyo kukho unxibelelwano obonelelo kunye nokususwa medium. Ngaphakathi kumhlathi iipleyiti ezikhethekileyo ezinemingxuma apho amanzi idlula. Oku kuyilwa ikuvumela kakhulu kwandisa ummandla zoqhagamshelwano aphakathi umphunga, yaye ngenxa yoko, ukuba shushu ngesantya esiphezulu.

iintlobo zezixhobo

Xa boilers mihla ingafakwa amanzi deaerator:

• ongenawo umoya;

• aspirated.

Xa Uhlobo lokuqala deaerators ukususwa yeegesi eziveliswa ukusuka amanzi vacuo. Ukwakhiwa kwamaziko eso ngokubanzi amanzi-jet okanye ejector umphunga. Uhlobo yokugqibela amaqhina lisetyenziswe ngokufuthi isiqu okanye ezisezantsi-power kwibhoyila systems. Endaweni yoko ejectors iimpompo ezizodwa zingasetyenziswa ukwenza cleaner. Ezinye ukunqongophala kwezixhobo efana degasser lwepolitiki, kukuba izibini kufuneka isuswe kuyo ngamandla, lo gama yena uyahamba aphume umoya ngendlela yemvelo - phantsi koxinzelelo.

Ngaphandle kwezi ntlobo zimbini kuxoxwa deaerator, kwibhoyila ekufuneka sifakwe isixhobo enoxinzelelo. Basebenza kwi 0.6-0.8 MPA. Ngamanye amaxesha circuit ubushushu kwibhoyila ikwathetha izixhobo xi eliphantsi.

Ububanzi bokusebenzisa

i de-empompeni ingasetyenziswa phi na? Yintoni na, ngoku uyazi. Ukususela kule divaysi ilungiselelwe degassing yokuvelisa medium, isetyenziswa ikakhulu apho kukho izixhobo zokufudumeza ezenziwe ngentsimbi.

Amaninzi, de-amaqhoshana zisetyenziswa kwiinkqubo zokufudumeza kunye namanzi ashushu. amagumbi Boiler kunye boilers zidla mayixhotyiswe izicwangciso cleaner-hlobo. Kwakhona bleeders ungasetyenziswa izikim ezinjalo esesibhakabhakeni. Lokulinganisa koxinzelelo ephantsi zaphezulu isicelo kwi kwiindlela ezininzi ezisebenzayo Bulelani kwibhoyila zomphunga. Iintlobo lokuqala (at 0.025-0.2 MPA) imvelaphi inyuselwa khona ngendlela iinjini abanamandla kakhulu, eyenzelwe inani elincinane abathengi. koxinzelelo iphakamileyo Lokulinganisa esetyenziswa kwiisekethe thermal kunye boilers, luphe into eninzi ngomphunga.

Poppet degasser: ukusebenza

Scheme zokuhlanjululwa igesi yaqaphela kwisigaba-ezimbini deaerators: udubulo (in a kwikholam) kunye kwiqamza (ngaphakathi etankini). Ukongeza, inkqubo ivulwa isixhobo kwamanzi ophuphumayo. Amanzi anikwe kumhlathi apho kunyuka iyenziwa. Ngaphezu koko, ayajika waya itanki, oko igcinwa khona kwaye akhutshelwa umva kwisixokelelwano. Umphunga ekuqaleni kufakwa BDA. Emva obala umqulu lwangaphakathi akungeni kwikholam. Ehambahamba emngxunyeni yetreyi iqamza, umphunga kumo amanzi kwiqondo lobushushu kufumaneka bantu.

Uqhushumbiso kususa onke amanzi avela yeegesi. Ngelo xesha kukho amafu umphunga. zaso ixubene irhasi sivete ukusuka eliphakathi kwaye akhutshelwa ezibandayo. Le condensate evela Umphunga akhutshelwa itanki yamanzi. Ngexesha neentlenge amanzi etankini amadlu lentsalela igesi amancinci siphuma kuyo. Amanzi isusiwe netanki yokugcina. Maxa wambi isitsha oxwesileyo zisetyenziselwa kuphela sokulungisa. Kufakelo ezinjalo, amanyathelo ezimbini degassing zibekwe kumhlathi.

Deaeration amanzi makeup

amanzi inkqubo ukufudumeza ujikeleza ngokuqhubekekayo. Kodwa isixa phezu kwexesha, nto leyo ezivuzayo, kodwa ngokuthe ngcembe kunciphisa. Ngoko ke, yenza-up amanzi anikezwa kwindlela ubushushu. Njengoko engundoqo, kufuneka bangenele inkqubo de-nomoya. Ekuqaleni, amanzi abetheka kungena imbawula, uze emva koko ehamba okucoca lokuhlanjululwa chemical. Ngaphezu koko, njengoko okunesondlo, ingena nenqaba deaerator. Ekhululwa amanzi oksijini aqukuqela ukuya pump kuqinise. Last eqondisa ibe eziphindaphindiweyo esingena okanye itanki yogcino.

chemical deaeration

Ngoko ke, impendulo umbuzo wokuba yintoni kwibhoyila deaerator ilula. Esi sixhobo senzelwe ukuba amanzi abilayo kunye ngomphunga eshushu ukususa ioksijini. Kodwa, ngamanye amaxesha yeegesi evela njengesipholisi yezityalo akwenziwanga swe ngokupheleleyo. Kulo mzekelo, zokuhlanjululwa ngakumbi kwibhoyila amanzi kungongezwa iintlobo ezahlukeneyo wezenzi eyenzelwe ukubopha ioksijini. Oku kunokuba, umzekelo, sodium sulfite. Kulo mzekelo, kuba deaeration amanzi esemgangathweni ukufudumeza yayo. Kungenjalo, basabela yemichiza iya kuba olucothayo kakhulu. Kwaye ukuze kukhawuleziswe inkqubo yokubopha oxygen zingasetyenziswa iintlobo ezahlukeneyo ehlanganisa. Maxa wambi amanzi deaerated ngokugqithisela ngokusebenzisa iphedi of pine metal oluqhelekileyo. Le yokugqibela kule meko ziye oxidized ngokukhawuleza.

Iimpawu obandayo

isixhobo deaerator akukho nzima kakhulu. Noko ke, ukufakelwa kwayo kufuneka wenziwe kunye nokugcina engqongqo zonke technologies amalungiselelo. Xa sikhokelwa nokufakela izixhobo iqhotyoshelwe kuqala kuyo imizobo umenzi kunye neprojekthi kwibhoyila. Ngaphambi kokuba uqalise ufakelo, khangela ufakelo waza wenza yayo kwakhona entry. Le iziphene ekhethiwe zithi nya. Eneneni inqubo yokufaka yena kubandakanya le manyathelo alandelayo:

• itanki zixhonywe kwisiseko;

• welding, noko phuphuma Senga;

• inxalenye esezantsi kumhlathi ziguyiwe phezu ubukhulu ngaphandle;

• ikholam zixhonywe itanki (kulo mzekelo ezisisigxina ngaphakathi iipleyiti kufuneka ibekwe tye);

• Ikholamu welding, ukuba itanki;

• bakhwela umphunga epholile kwaye zibamba amanzi;

• ngokungqinelana ne imizobo ukuba kokuxhuma iindlela;

• beka uvala elawula semigudu ;

• izixhobo uvavanyo olwenzelwa hydraulic.

ufakelo wokutshiza

Uyilo ngasentla kuthiwa Belleville. Kukho kwakhona spray bleeders. Devices elolu hlobo isetyenziselwa ngaphantsi kananjalo oxwesileyo itanki yokugcina obunamandla. Ukungabikho kwimiqolo - loo nto eyenza a degasser. Siseko operation kwakhona eyahlukileyo kancinci. Le umphunga ikhutshwa kwi izityalo ezo ngezantsi - ukusuka itanki sime ikama tye. Isikhongozeli ngokwayo yahlulwe yaba kwindawo preheating kunye deaeration. Boiler amanzi feed nakwesiphi inxalenye yokuqala kubekwe phezu డొమైన్ idomeyini. Apha, itshiswa ukuya abilayo kunye aqukuqela aye kummandla deaeration apho kunyuka oxygen isuswe lulo.

Ngoko, nantso yonke into enokuthethwa kwisixhobo efana deaerator. Yintoni na, siyathemba ukuba ukuqonda, kuba siye sikunike kakhulu impendulo eneenkcukacha lo mbuzo. Ngoko ke ukubiza ukusetha, ukubonelela nokusebenza rhoqo amanzi kunye nomphunga boilers ezishushu. Ezikhethiweyo iintlobo kunye neendlela nokufakelwa kwezixhobo lwenziwa ngokungqinelana iinkcukacha ze izixhobo zokufudumeza kunye neprojekthi kwibhoyila.
