Isitshixo somshushu wokutshisa: umgaqo wokusebenza. I-Plate heat exchangers: ifowuni

Ukutshintshisana kwamanzi kuyilula kwiinkqubo zokwakha, ngokuqhelekileyo kubandakanywa kwizicwangciso zeentlobo ezahlukeneyo zezixhobo zokusebenza. Ngamanye amaxesha basetyenziselwa ukupholisa indlu kunye neenkqubo zomoya. Njengoko sele sele ikwahlulelwa ngamagama, ezi zixhobo zenzelwe ukuthatha ubushushu ukusuka kwelinye eliphakathi kwaye zithumele kwelinye.

Iintlobo eziphambili zezoshishino zokutshintsha

Kwizixhobo ezizodwa, iintlobo ezahlukeneyo zezixhobo ezifanayo zingasetyenziselwa: i-twisted, graphite, i-shell-and-tube, i-spiral, njl. Nangona kunjalo, uhlobo oluchanekileyo lwezoqoqosho, olusebenzayo noluninzi luyi-plate exchange exchanger. Umgaqo wokusebenza kwawo usekelwe ekugqibeleni ukutshatyalaliswa kobushushu ngetsimbi. Kule meko, ubungakanani belo hlobo lomthengisi bancinci, kwaye ixabiso liphantsi. Ezi zixhobo zingasetyenziswa kwizixhobo zeenjongo ezahlukeneyo.

Impawu zoKwakha

Isitya sokutshisa umtshini, isistim kunye nomgaqo wokusebenza (izicwangciso ezinikezelwe kwinqaku liqinisekisa le nto) zinyani kakhulu, ziqulethwe ezi zinto zilandelayo:

• I-Front plate eqingqiweyo kunye namaqabunga. Ngaloo mva, zombini iindaba ezisebenzayo ziwela kwishushu.
• Imisongo yesikhokelo esezantsi nephantsi. Ezi zixhobo ziyimfuneko ekuqiniseni isakhiwo sonke. Umsebenzi ofanayo wenziwa yenkxaso yangemva yesixhobo.
• Iplani ehambayo ehamba phambili.
• Amacwecwe ngokwabo.
• Ukufakela iibhasiki ezikhonzayo ngexesha elifanayo njengabadilili phakathi kwamacwecwe.

Maxa wambi ama-buses e-heat exchange exchangers ayifakwanga kuphela ngaphambili, kodwa nakwi-panel yangaphambili. Kule meko, yonke into ixhomekeke kwinjongo yeso sixhobo kwaye ingafakwa njani kwinkqubo. Xa kuhlanganiswa ukutshatyalaliswa kobushushu, iimveliso ezihlukeneyo nazo zisetyenziselwa: ukulungisa iibhentshi, ukuhlanjululwa kweerubha, njl njl.

Umtya wokutshisa umhla wamanzi: umgaqo wokusebenza

Isixhobo salolu hlobo sisebenza kwisikimu esinqamlezileyo. Amacandelo azaliswe ngokuzenzekelayo ngomoya ocolileyo kunye ocolile. Ukutshintshisana kwamanzi phakathi kwabo kuvela kwiiplate. Ukuzaliswa kwamacandelo ngethuba lokusebenza kwesixhobo linikezelwa ngamagqabantshintshi ahlukeneyo. Umva wokugqibela unokuvumela ukuhamba phakathi okanye ukulibaziseka. Njengoko ubona, lo ngumgaqo olula kakhulu womsebenzi. I-Plate heat exchangers ihlelwe ukwenzela ukuba abeendaba bahambelane. Kule meko, ukufudumala kunikezelwa ukusuka phezulu kwaye ushiya umbhobho wegatsha ophantsi, kunye ne-cooled, ngokulandelanayo, ngokuchaseneyo.

Ngaloo ndlela zonke izixhobo ezinjalo zisebenza. Umgaqo wokusebenza kwesitya sokutshisa i-DHW ifana ngokufanayo kunye neendlela ezilungiselelwe ukulungiswa kwemimiselo, i-lubricant lubricants and so on. Ukwahlukana okukuphela kwimiba yokudlula phakathi kwinqanaba. Kwimodeli yamanzi ashushu, kukuthi, ngokulandelanayo, amanzi, kwezinye iifowuni zolu hlobo, utshintsho lunokuvela phakathi kwezisombululo, i-oli, i-gesi, njl.

Iinkcukacha zobugcisa

Xa ukhetha i-plate exchange exchangers, ngokuqhelekileyo unake ingqalelo kwiinkalo ezinjengale:

• Amandla;
• Iindleko;
• Izinto kunye nommandla wamacwecwe;
• Gcoba impahla;
• Iqondo lokushisa;
• Ubungakanani obuvumelekileyo bukhulu kwi-media;
• Uxinzelelo oluninzi lokusebenza.

Iiplati zeDivaysi

Ngaloo ndlela, siye safumanisa ukuba luhlobo luni lomgca wokutshatyalaliswa kobushushu umgaqo wokusebenza. Isixhobo seplate kule sixhobo esilula ukuyisebenzisa. Kuzo nganye zikhomo ezi-2 ngaphantsi. Ukongezelela, iiplate ziyakwazi ukufumana uncedo oluququzelela ukuhamba kwamanzi okanye iigesi. Ubuninzi babo buxhomekeke kwinjongo, ubukhulu becebo kunye noxinzelelo kulo.

Ekubeni ezi zinto ziyi-design exchanger zihlala zihlala kwindawo enobundlobongela, kufuneka zenziwe kwizinto ezizinzileyo kunokwenzeka. Ngokuqhelekileyo, ezi zicwecwe zenziwe ngensimbi engenasici. Kule meko, i-brand 1.4404 / AISI 316L isetyenziswa rhoqo. Le ntsimbi iqulethe i-molybdenum, kwaye ngoko iyaziwa ngokuxhatshazwa kwenyango, umonakalo kunye nokuchithwa kwe-chloride.

Kwimeko apho kungabikho imidiya enobundlobongela obudlulayo kumashishini okushisa, izikolo eziqhelekileyo ze-stainless steel can be used to make plates. Ngokuqhelekileyo ezi zinto zenziwe ngeetanium okanye titanium-palladium. Kusetyenziswa kwimveliso yabo kunye nezinye izinto.

Ukufudumala ukutshatyalaliswa kwamatywina

Ukuhlala kunye nokuthembeka kokutshatyalaliswa kobushushu kuxhomekeke kumgangatho walezi zinto. Izicwangciso zithintela ukuxuba amajelo kwaye zikhokele ngendlela ethile. Ngeli xesha, zimbini iindidi zezinto ezinjalo zisetyenziselwa ukutshintshisa ukushisa: i-clip-on kunye ne-glue. Ukuveliswa kwee-gaskets, izinto ezisetyenziswayo ze-rubber zisetyenziswa rhoqo. Kungaba, umzekelo, i-EPDM, i-PVR, i-Viton, njl.

Izibonakaliso ezixhasayo zenziwa kwiindawo ezikhethiweyo kwi-epoxy. Utshintsho lweefayili lufakwe ngeendlela zokulungisa izinto ezikhethekileyo.

Amandla kunye nokusetyenziswa

Sebenzisa umtshini wokutshisa i-plate, umgaqo wokusebenza kunye noyilo ulungeleka, unokuba kwiinkalo ezahlukeneyo zoqoqosho. Kwaye ke, amandla ezo zixhobo ahluka phakathi kweendawo ezininzi. Kuza kube namhlanje, ukutshatyalaliswa kobushushu kwii-kilowatts eziliqela ukuya kuma-megawatts amashumi kusetyenziswa kwiindidi ezahlukeneyo zokufudumala kunye nokupholisa. Esi sibonakaliso sincike kakhulu kwinani lamacwecwe asetyenziswa kwisixhobo kunye nobukhulu bawo.

Ukutshintshiselwa kwamashishini anamhlanje oku nohlobo olusebenzayo lunokusebenza kumgangatho weqondo lokushisa (-30 ukuya ku-200 ^о С). Eyona nto, xa kunjalo, ukuba imidiya ekhuhlileyo kunye nefuthe iyanelungele ngokufanelekileyo. Nangona kunjalo, iplatshi yokutshisa abatshintshiselwano ayinakucinga ngokukodwa kule nkalo. Kwimizekelo emininzi, ubungakanani obukhulu obukhulu obungenayo i-particle kwi-medium buyi-4 mm.

Ukushisa kunye noxinzelelo

Kuye kweli lizwe ilizwe lokutshisa ukushisa lenziwa ngokubanzi phantsi kweGOST 55118-83. Ezi zixhobo kwiimeko ezininzi ziyakwazi ukumelana neengcinezelo ukuya kwi-1.6 MPa. Ubushushu beendaba ezisebenzayo kwiimodeli zasekhaya zingaguquleka ngaphakathi -30 ... +180 degrees.

Ububanzi besicelo

Isitya sokutshisa umtshini, umgaqo wokusebenza ovumela ukuba udibaniswe kwiinkqubo ezahlukeneyo ezahlukeneyo, unokusetyenziswa:

1. Kwimveliso yokucwangcisa. Ngokusetyenziswa kwezixhobo ezinjalo, i-lubricating fluids, i-oil hydraulic kunye ne-oil oil, njl.
2. Kwiinjini zeepiston kunye neenjini.
3. Kwizikhululo zamandla.
4. Kwi-compressors.
5. Kwi thumela. Kwiinqanawa, ukutshatyalaliswa kobushushu kusetshenziselwa ukupholisa okuphakathi.
6. Kwi shishini elikhanyayo.
7. Ukwakhiwa komatshini kunye nokusetyenziswa kwesebe.
8. Ukufudumala kunye nesimo somoya.

Isitya samashishini eshushu samanje, isixhobo kunye nomgaqo wokusebenza okuxoxwa ngawo ngokucacileyo kweli nqaku, ngoko kungathatyathwa njengokwethenjelwayo, eyiyo kwaye ifanelekile ukuyisebenzisa. Kuzo zonke ezinye izinto, kwaye umise imizekelo enokuqhathaniswa nezinye iintlobo ezingenangqiqo. Konke oku kwenza ukuba basebenzise kwiindidi ezahlukeneyo zokupholisa kunye nokufudumala ngaphandle kweengqiqo.
