Plate Exchanger kye kika ky’ebyuma ebiwanyisiganya ebbugumu, ekirina ebirungi ebyuma ebirala ebiwanyisiganya ebbugumu bye bitasobola kukwatagana: Kirina omugerageranyo gw’okutambuza ebbugumu omungi, okufiirwa ebbugumu okutono, ekigere ekitono, ensengekera ya compact era ekitangaala, ebyangu okuddaabiriza n’okuyonja,okuwanyisiganya ebbugumu ku plate kulina okukozesebwa okw’enjawulo n’obulamu obuwanvu. Naye era zirina ebizibu ebimu, nga puleesa tesobola kusukka 2.5MPa, ebbugumu teriyinza kusukka diguli 250 Celsius, teriyinza kuwaanyisiganya bbugumu ku butundutundu obunene n’ebiwuzi ebiwanvu, tebisobola kukozesebwa mu mbeera y’okukola okukosa ennyo, era batera okuzibikira. Wammanga kwe kwekenneenya ebimu ku bintu ebitali bya bulijjo ebitali bya bulijjo eby’Ebiwanyisiganya ebbugumu .:
Ensonga enkulu:
Okugerageranya/okuzibikira obubaawo obuwanyisiganya ebbugumu: ayoni za kalisiyamu ne magnesium n’obucaafu mu mazzi biteekebwa ku ngulu w’embaawo, ne bikola layeri ya minzaani erimu obutambuzi bw’ebbugumu obutono ennyo; Amazzi Short Circuit: Gaasi ezisiba pulati zikaddiwa oba zikwatagana bulungi,kino kireetera amazzi agamu agannyogoga n’ago agookya okutabula butereevu nga tegabadde mu kuwaanyisiganya ebbugumu; Plate Channel Blockage: obutundutundu obugumu n’ebiwuzi (nga amazzi amakyafu n’ebikuta) mu mazzi bisibiddwa mu kitundu ekilungamya plate oba omukutu gw’okukulukuta, ekikendeeza ku kitundu ekikola eky’okuwanyisiganya ebbugumu.
Okugonjoola:
01
Okuggwaamu amaanyi kw’eddagala (olw’okugerageranya):
Yimirirako ebyuma, fulumya amazzi, era ofuuwe n’ekirungo ekinafu eky’okuyonja asidi (nga 5%-8% citric acid solution okwewala okukulukuta kw’ebyuma ebitaliimu buwuka) okumala essaawa 2-4,
02
Oluvannyuma naaba n’amazzi amayonjo okutuusa nga tebiriimu;
03
Tokozesa solutions ezikola ennyo nga hydrochloric acid (ekiyinza okwanguyiza okwonoona plate passivation film).
04
Okwoza mu mubiri (okuzibikira):
Salamu ekyuma ekikyusa ebbugumu, ggyawo ebipande, era ofukumula omukutu gw’okukulukuta n’emmundu ey’amazzi ey’amaanyi-enyigirizibwa (pressure less than or equal to 0.8MPa okwewala okukyukakyuka kw’ebipande);
Ensonga enkulu:Okukaddiwa/okwonooneka kwa gasket: okuwanvuwa-Term high temperature and pressure fluctuations kireetera gaasikiti okufiirwa elasticity, oba okukulukuta kw’amazzi (nga amazzi aga asidi) kireetera gaasikiti okuzimba n’enjatika; plate deformation/misalignment: Okunyweza obutafaanagana kwa bulooti mu kiseera ky’okukuŋŋaana oba okuwanvuwa-okuyitirira okunyigiriza okusukkiridde kuleeta ebitundu by’okusiba n’okusiba ebikalu; Flange Seal Okulemererwa: Gaasi za flange eziyingira n’ezifuluma emyaka, oba obuuma bufuuka buyitirivu (nga bukyusakyusa mu bbugumu n’okunnyogoga kireetera obuuma okugaziwa n’okukonziba). Okukulukuta kw’okuggalawo kusinga kuva ku kutandika emirundi mingi-okudda waggulu n’okuggalawo ekikyusa ebbugumu, era okuzzaawo embeera z’emirimu eza bulijjo kisoboka; Okukulukuta okw’omunda kusinga kuva ku gaasikiti ezonooneddwa n’okukulukuta kw’epulaati n’okutomera;Ensonga enkulu ezivuddeko okukulukuta okw’ebweru kwe kukyusakyusa, okufulumya, okwonooneka kwa gaasikiti y’okusiba, okukulukuta n’okukyukakyuka kw’epulati, n’okulemererwa okunywezebwa ku sayizi y’okunyweza ekiragiddwa; Ensonga enkulu evuddeko okukulukuta wakati w’ekyuma ekizibe n’ekyuma ekisiba (clamping plate) kwe kuba nti ekyuma ekizibe kifumitiddwa ebintu ebikaluba.
Ekigonjoola:Okujjanjaba amangu: Amangu ddala kendeeza ku puleesa y’enkola, ggalawo vvaalu eziyingira mu bbugumu n’okufuluma (Ggalawo oludda olwokya, olwo oludda olw’ennyogovu), amazzi gafukumula amazzi n’okuggala; Kikyuseemu ebisiba: Salamu ekyuma ekikyusa ebbugumu, ggyawo gaasi zonna,kebera ekisenge ekisiba ebbakuli okusobola okukunya (bwe kibaawo, kiweweevu n’omusenyu omulungi); Kikyuseemu gaasikiti okusiba n’ekika kye kimu (kirungi okukozesa ebbugumu-ebintu ebiziyiza n’okukulukuta-, gamba nga nitrile rubber for oil ne EPDM for water/weak alkali);okuddamu okunyweza n’okunyweza: stack plates in the original order (plate numbers must be aligned to avoid reverse installation), and tighten tighting the evenlely (eventlen) diangon) leads)
Enjawulo wakati w’ebipima puleesa ebiyingira n’ebifuluma eby’ekikyusa ebbugumu esukka omuwendo gwa dizayini (okugeza, puleesa ya dizayini ekka 0.1MPa, naye puleesa yennyini ekka okutuuka ku 0.3MPa); Puleesa y’okufulumya pampu yeeyongera, naye .Ekyuma ekikyusa ebbugumu .Omuwendo gw’amazzi agayingira mu mubiri gukendeera (pampu etikkira nnyo ate amaloboozi ne geeyongera).
Ensonga enkulu:Okuzibikira kw’omukutu gw’okukulukuta: obucaafu mu mazzi (nga omusenyu n’obusagwa) biteekebwa mu mukutu gw’okukulukuta kw’embaawo, okukendeeza ku musaalaba gw’okukulukuta-ekitundu eky’ekitundu;Ennamba enkyamu oba ekika ky’embaawo: Omuwendo gwennyini ogw’okukulukuta gusukka nnyo omuwendo gw’okukola dizayini, oba omukutu gw’okukulukuta kw’epulaati gufunda nnyo (okugeza, ekipande ekitono kikozesebwa okukola ku mazzi amanene; Obugumu bw’amafuta bweyongera ku bbugumu eri wansi), oba amazzi galimu ekintu ekinene ekiyimiriziddwa (nga slurry), ekivaamu okuziyiza okukulukuta okweyongera.
Ekigonjoolwa:Oyoza omukutu gw’okukulukuta: Oluvannyuma lw’okuggala, ssala ekyuma ekikyusa ebbugumu era ofukumula omukutu gw’okukulukuta kw’epulaati n’emmundu ey’amazzi eya waggulu-ekozesa omupiira ogw’enjawulo (nga dayamita ntono nnyo okusinga obugazi bw’omukutu gw’okukulukuta) okugogola okuzibikira; Teekateeka ebipimo by’okukola: Singa omuwendo gw’amazzi agakulukuta guba munene nnyo, kikendeeza mu ngeri esaanidde emirundi gya pampu (gifuze mu bbanga lya ±10% ku muwendo gw’okukulukuta kw’abakola dizayini); Singa ekizimbulukusa ky’amazzi kiba waggulu, yongera ku bbugumu ly’amazzi agayingira (nga okubugumya woyiro okutuuka ku bbanga erisaanira ery’obuzito), oba teekako ekyuma ekigifumbisa ku mulyango oguyingira.
A:Ebbugumu erifuluma ku ludda ery’ebbugumu lisinga omuwendo gwa dizayini. Ensonga enkulu ze zino: Ekizibu ky’okusunsula, omuwendo gw’okukulukuta kw’oludda ogwokya gusinga omuwendo gwa dizayini, ebbakuli zizibiddwa oba omuwendo gw’okukulukuta kw’oludda olw’ennyogovu guba mutono;
B:Ebbugumu erifuluma ku ludda ery’ennyogoga liri wansi nnyo. Ensonga enkulu ze zino: okukulukuta okutono okw’ebbali okw’ebbugumu oba ebbugumu erya wansi okusinga omuwendo gwa dizayini, okuzibikira pulati, n’ebirala.
