Waa maxay dahaarka ka horreeya boodhka ee guryaha shaandhada bacda? Sidee loo mariyaa siigada?

Bacaha shaandhaynta boodhka ee dahaarka ka hor ama abuurka boodhka macneheedu waxa weeye hore ugu xidh boodhka gargaarka shaandhaynta ee dusha bacaha boodhka ka hor inta aanay nidaamyadu si caadi ah u socon marka la rakibo bacaha cusub.
Faa'iidooyinka sida soo socota:
1. Marka boodhka ururiyaa bilaabo, gaar ahaan muddada hore, hawada boodhka waxaa laga yaabaa inay ku jirto qoyaan badan, sidoo kale waxaa ku jira qaar ka mid ah saliidda dabka oo aan dhamaystirnayn, kookaha saliidda dhegdheg ah iyo sidoo kale qalabka hydrocarbon iyo wixii la mid ah, haddii bacaha shaandhada leh horay loo dahaadhay. , Qalabkan qoyan ama dhejiska ah si toos ah uma taaban doonaan bacaha shaandhada, markaa ma fududa in la keeno dhibaatooyinka xannibaadda ama daxaleeyaan bacaha shaandhada, sidaas darteed waxay sii dheerayn karaan nolosha adeegga bacaha shaandhada.
2. Marka hawada siigada ay leedahay qaar ka mid ah walxaha acid, sida SOx iyo wixii la mid ah kuwaas oo laga yaabo inay u baahdaan in la geliyo qaar ka mid ah budada alkali, sida CaO, laakiin bilawga adag si aad u hesho nuxurka ku haboon ee walxaha si loo geliyo, haddii aan horay loo helin. lakabka dahaarka, waxa laga yaabaa inay daxaliyaan bacaha shaandhada wakhti hore.
3. Sidoo kale lakabka difaaca ee dusha sare ee bacaha shaandhada, ayaa gacan ka geysan kara kordhinta waxtarka shaandhada ee bacaha cusub.

Laakin sidaad hore ugu xidhi lahayd bacaha shaandhada boodhka leh boodhka gargaarka shaandhada?
Marka loo eego waayo-aragnimada shaqo ee muddada dheer, Zonel Filtech waxaa la siiyay talooyinka soo socda ee macmiilkayaga si loo tixraaco:
a. Shuqullada hore ee dahaarka waxay u baahan yihiin inay habeeyaan ka hor shidida kuleyliyaha ama soo saarista, oo ay joojiyaan nidaamyada nadiifinta, fur furka galka hawada boodhka.
b. Daar marawaxada oo si tartiib tartiib ah u kordhi socodka hawada ilaa ay la kulanto 70% ee nashqada, oo duub caabbinta qolalka kala duwan.
c. Geli siigada gargaarka shaandhada ka soo daloosha marinka tuubada weyn.
Sida caadiga ah cabbirka qashinka gargaarka filter wuxuu ka yar yahay 200 micron, qoyaanka qoyaanka ka yar 1%, saliid la'aan, tirada boodhka loo baahan yahay in la geliyo waa 350 ~ 450g / m2 marka loo eego aagga shaandhada.
d. Ka hor inta aanad gelin boodhka gargaarka shaandhada, hubi in mugga socodka hawadu uu ka badan yahay 70% ee naqshadaynta, oo hubi in waalka dhaafa uu xidhan yahay, waalka wiishku uu khadka ku jiro. Marwaxadu waxa ay u baahantahay in ay shaqeyso ilaa 20 daqiiqo marka ay dhamaato siigada gargaarka shaandhada ku darista, hubi in boodhka uu si siman ugu dahaadhay bacaha shaandhada.
e. Marka shaqada hore ee dahaarka la dhammeeyo, iska caabbinta sida caadiga ah waxay kordhin doontaa qiyaastii 250 ~ 300Pa, haddii caabbinta aysan kor u qaadin sida la codsado, taas macnaheedu waa hawlgalku wuu fashilmay, waxaa laga yaabaa inuu u baahdo inuu ku celiyo nidaamka mar kale.
f. Marka ay dhammaato shaqada dahaarka ka hor, jooji marawaxada, kormeeruhu waxa uu aadaa guriyaha hawo nadiifka ah si uu u hubiyo in ay wax soo daadanayaan iyo in kale, haddii ay haa tahay, waxa laga yaabaa in ay u baahdaan dib u hagaajin.
g. Haddii aan daadin iyo dhammaan xogta si caadi ah loo muujiyay, markaas waxay ku shaqayn kartaa si waafaqsan xogta la qorsheeyay, fur nidaamka nadiifinta oo u shaqaynaysa si caadi ah.
