Kwimizi-mveliso eshushu kakhulu efana nentsimbi, iglasi, kunye neeseramikhi, izitofu ezivuselelayo zigcina amandla kwaye zinciphise ukukhutshwa komoya ngokusebenzisa iteknoloji yokubuyisa ubushushu obumdaka begesi yolwelo.isidambisi segesi yolweloIvalvu yebhabhathane yomoya, njengenxalenye ephambili yenkqubo yokuguqula umbane, yenza umsebenzi obalulekileyo wokutshintsha indlela yokuhamba kwegesi yolwelo kunye nomoya (okanye ipetroli). Ngenxa yeempawu zayo zokuguqula umbane ngokusebenza kakuhle, ulawulo oluchanekileyo, kunye nokumelana neendawo ezinzima, iye yaba sisiqinisekiso esibalulekileyo kwiifeni zanamhlanje zoshishino ukuphucula ukusebenza kakuhle kwamandla kunye nokunciphisa ungcoliseko.

Umgaqo Wokusebenza: Ulwakhiwo Lweendlela Ezintathu Zokutshintsha Kweendlela Ezimbini

Ivalvu yedamper ye-bypass ezintathuIvalvu yebhabhathane yomoya isebenzisa isakhiwo esineendlela ezintathu esimile okwe-'Y' esineendawo ezimbini zokungena (A, B) kunye nesinye sokuphuma (C), okanye iindawo ezimbini zokungena (B, C) kunye nesinye sokuphuma (A), nto leyo efikelela ekutshintsheni ngokukhawuleza komjelo wolwelo kwipleyiti yevalvu ejikelezayo. Imigaqo yayo ephambili yile:

1. Ukuhanjiswa Kwangaphambili: Ipleyiti yevalvu ijikeleza kwi-engile ethile, idibanisa i-inlet A kwi-outlet C ngelixa ivala i-inlet B.

2. Ukubuyela umva: Ipleyiti yevalvu ijikeleza i-180°, idibanisa i-inlet B kwi-outlet C ngelixa ivala i-inlet A.

Kwii-oven ezivuselelayo, ezi valve zihlala zisetyenziswa ngababini ukulawula ukubuyiselwa komoya ophuma kwigesi yeflue kunye nokufakwa komoya/ipetroli ekutshisweni. Xa zidityaniswe nee-regenerators, zenza ukuba ubushushu obungafunekiyo bubuyele kwicala elinye kwigesi yeflue, nto leyo eyandisa ukusebenza kakuhle kobushushu be-oven nge-30%.

Iingenelo eziphambili ze-damper ye-butterfly valve yobushushu obuphezulu: Ukusebenza kakuhle, Uzinzo, kunye nobukrelekrele 

1. Ukubuyela umva ngokukhawuleza kwinqanaba le-millisecond ukuze kusebenze i-furnace eqhubekayo

Ipleyiti yevalvu isebenzisa izinto ezikhaphukhaphu (umz., i-aluminium alloy, ii-carbon fiber-reinforced composites) kwaye idibene nee-actuators zomoya okanye zombane, nto leyo enciphisa ixesha lokubuyela umva libe ngaphantsi kwe-500 milliseconds. Oku kususa "umsantsa wokuphazamiseka kokuhamba" kweevalvu zesango zendabuko, kuqinisekisa ubushushu obuzinzileyo besithando somlilo kunye nokunciphisa ukuguquguquka kwenkqubo okubangelwa kukubuyela umva.

2.Ulwakhiwo lokutywina oluphindwe kabini lokumelana neMedia eNgqwalisayo yobushushu obuphezulu

Ivalvu isebenzisa uyilo lwetywina eliqinileyo lesinyithi kunye noyilo lwetywina elithambileyo elithambileyo:

- Ipleyiti yevalvu kunye nomphezulu wokudibana komzimba: Igqunywe ngee-alloys ezishushu kakhulu (umz., i-Inconel, i-Hastelloy) okanye ii-ceramic coating ukuze zikwazi ukumelana nokukhuhla igesi yolwelo ngaphezulu kwe-1200°C.

- Iiringi zokutywina: Zenziwe ngerabha ye-silicone, i-fluororubber, okanye ii-graphite composites, zigcina ukuthamba kumaqondo obushushu aphezulu ukuze zingavuzi.

Ilungele iindawo ezinegesi erhabaxa equka uthuli kunye ne-sulfur oxides.

3. Ukumelana Nokuhamba Okuphantsi Kokonga Amandla

Ipleyiti yevalvu emile okwediski iphantse ilingane nolwelo xa ivuliwe ngokupheleleyo, kwaye i-flow resistance coefficient yi-1/3 ukuya kwi-1/5 kuphela kune-gate valves, nto leyo enciphisa kakhulu ukusetyenziswa kwamandla efeni. Isiphumo sokonga amandla siphawuleka ngakumbi kwiimeko zokuhamba kwamanzi amakhulu (umz., ngaphezulu kwe-100,000 m³/h).

4. Ulawulo olukrelekrele lweemeko ezintsonkothileyo

Ivalvu idibanisa izinzwa zendawo, iitransmitter zoxinzelelo, kunye neenkqubo ze-PLC/DCS ukuze zisebenze:

①Ingqiqo yokuguqula umva enokulungiselelwa ngokwezifiso: Ukulungisa imijikelo yokuguqula umva ngexesha langempela ngokusekelwe kubushushu besithando kunye noxinzelelo.

②Isilumkiso sangethuba: Ukufumanisa izinto ezingaqhelekanga ezifana nokuxinana kwepleyiti yevalvu okanye ukungaphumeleli kwetywina kunye nokutshintshela ngokuzenzekelayo kwimowudi yogcino.

③Ukugcinwa kude: Ukubeka iliso kwimeko yevalvu ngokusebenzisa amaqonga e-IoT ukunciphisa iindleko zokuhlolwa ngesandla.

Usetyenziso lwevalvu yebhabhathane eneendlela ezintathu Imeko: Izisombululo eziguquguqukayo zokuguqula izinto zefenitshala yemizi-mveliso 

1. Ishishini leNsimbi: IiFurnaces zokuFudumeza kunye neeFurnaces zokuNyanga uBushushu

Kwii-oven zentsimbi eziphinda zifudumale, iivalvu zebhabhathane ezineendlela ezintathu zitshintsha igesi yolwelo kunye nomoya ukuze zidlulisele ubushushu begesi yolwelo olushushu kakhulu kwizixhobo zokuhlaziya. Umoya ophinda ufudumale emva koko uthwala ubushushu uye kwi-oven, nto leyo ebangela ukutsha okuphinda kuvuseleleke kabini kwaye inciphise ukusetyenziswa kwamafutha ngama-20%–40%.

2. Izithando zeglasi/zeseramikhi: Ukunyibilika okuSebenzayo kunye noLondolozo lwaMandla

Kwiinkqubo zokubuyisela umva i-oven yeglasi, iivalvu zitshintsha ngokukhawuleza izikhokelo zokuhamba kwegesi nomoya, zinciphisa ukukhutshwa kwe-NOx ngelixa ziphucula ukusebenza kakuhle kokunyibilika kweglasi. Kwii-oven ze-ceramic roller, iivalvu zilawula indlela yokujikeleza komoya oshushu ukuze zilungelelanise ubushushu be-oven kwaye zonyuse isivuno semveliso.

3. Izixhobo zeKhemikhali nezokwakha: Ukuphathwa kweendaba okuntsonkothileyo

Kwiinkqubo zegesi zomsila wekhemikhali ezinetha kunye nothuli, iingubo zevalvu ezingagugiyo kunye nezakhiwo ezizicocayo zithintela ukuvaleka. Kwiinkqubo zokuvelisa umbane oshushu kwi-oven yesamente, iivalvu zitshintsha igesi yobushushu obuphezulu kunye nomoya opholileyo ukuze kuphuculwe ukubuyiswa kobushushu obumdaka.

4. Izixhobo zoKhuseleko lweNdalo: ii-RTO Regenerative Thermal Oxidizers

Kwizixhobo ze-RTO zonyango lwe-volatile organic compound (VOCs), iivalvu zebhabhathane ezineendlela ezintathu zilawula ukukhupha umoya kunye nokubuyisela umva igesi ecocekileyo, ukuqinisekisa ukusetyenziswa kobushushu obupheleleyo kwee-regenerators ngelixa zinyamezela amaqondo obushushu aphezulu akhawulezileyo ngexesha lokutsha.
