ʻOiai ke kumu kūʻai kiʻekiʻe, ʻoi aku ka maikaʻi o nā pahu hoʻoheheʻe wai kila i ka hoʻohālikelike ʻana i nā kumukūʻai o ke ola a pono e hōʻike ʻia e like me ia.
ʻO nā mea hoʻomehana wai o ka hale ka mea maoli o ka honua mechanical. Ua ʻike pinepine ʻia lākou i nā wahi ʻino loa a ʻaʻole mālama ʻia kā lākou hana paʻakikī. Ma ka ʻaoʻao wai o ka mea hoʻomehana, hoʻouka ʻia nā minerala, oxygen, kemika a me ka lepo.
I ka wā e pili ana i ka mālama ʻana, ʻaʻole mālama ʻia nā mea hoʻomehana wai wela o ka hale.
Hiki ke hoʻomaikaʻi ʻia kēia ola pōkole? ʻO ka hoʻohana ʻana i nā mea hoʻomehana DHW i hana ʻia i ke kila kila kekahi ala e hoʻonui ai i ke ola.
ʻO ke kila kila ka inoa maʻamau no nā ferrous alloys me ka chromium maʻiʻo o ka liʻiliʻi loa o 10.5%. ʻO nā mea ʻē aʻe e like me nickel, molybdenum, titanium a me carbon hiki ke hoʻohui ʻia e hāʻawi i ke kūpaʻa corrosion, ikaika a me ka formability.
Inā ʻōlelo mai kekahi "hāʻawi mai iaʻu i kekahi mau paipu plastik" he aha kāu e lawe mai ai? PEX, CPVC, polyethylene? He mau paipu "plastic" kēia mau mea a pau, akā he ʻokoʻa loa ko lākou mau waiwai, ikaika a me nā hoʻohana. Pela no ke kila kila. Aia ma luna o 150 mau māka o ke kila kila, nā mea like ʻole a me nā noi. 6Ti a me 444.
ʻO ka ʻokoʻa ma waena o kēia mau māka ʻo ia ka neʻe ʻana o ka alloy i loko. a crevice corrosion i loko o chloride environments.316Ti grade titanium haawi ia maikai formability a me ka strength.Grade 444 i ka chromium a me ka molybdenum, akā, 'aʻole ia i kekahi nickel.General olelo, o ka nui nickel, molybdenum, a me ka titanium i loko o ka hui, i ka maikai o ka corrosion ke kū'ē a me ka ikaika ole. nā māka no ka mea ʻaʻole like ka maikaʻi
Hoʻohana ʻia ke kila kila i nā ʻano ʻano like ʻole o ka wai.
ʻO ka hana ʻana i ke kila kila he ʻāpana nui o kēia mau mākeke kūʻokoʻa ʻEulopa. Ma Kanada, loaʻa nā pahu kuhili ʻole a me ke aniani-lined steel indirect tanks, stainless steel tanks usually carry a higher price tag. ʻO ka mākeke hoʻomehana wai. ʻO ke kila kila me ka uhi aniani ka mea maʻamau i kēia māhele. Hoʻohana maʻamau ʻia ke kila kila i loko o ka tankless a i ʻole ke kī pololei ʻana i nā pahu condensing wai.
No ka hoʻonui ʻana i ka pono o kēia mau mea, pono e hoʻomaʻalili ʻia ke kinoea flue ma lalo o ka wahi hau e hoʻokuʻu ai i ka wela huna o ka wahie. ʻO ka condensate ka hopena i hoʻomaʻemaʻe maoli ʻia ka mahu wai mai nā huahana hoʻopau kino, he haʻahaʻa loa ka pH a me ka acidity kiʻekiʻe.
ʻO nā mea hoʻololi wela i hana ʻia i ke kila maʻamau a i ʻole ke keleawe he paʻakikī ke kū i kēia condensate flue gas no nā manawa lōʻihi. .97.
Ke hoʻomaka nei ka hoʻohana pinepine ʻana o nā pahu wai wai me ka ʻenehana condensing, ʻoi aku ka nui o nā hoʻololi o ka hale e koi ana i ka pono o ka mea hoʻomehana wai kiʻekiʻe. -ʻaʻole maʻamau ka pahu kila kila a me ka hana coil, akā aia kekahi mau mea hana kila-stainless i loaʻa.
ʻO ke kumu kūʻai mua o ka pahu aniani he haʻahaʻa loa, a ʻo ka manawa wale nō e haʻi i ke ʻano o ke kūpaʻa ʻana o ka mea hoʻololi wela i nā wahi condensing koʻikoʻi. ʻO kēia mau mea hoʻomehana wai condensate hou e hiki ke hoʻokō i nā pono kiʻekiʻe ma mua o nā mea hoʻomehana wai i puhi ʻia, me nā mea wela wela mai 90% a 96%. .
E nānā pono i nā pahu hoʻomehana wai a e ʻike ʻoe ʻo ka hapa nui o nā ʻano o ka pahu kī pololei, ʻōwili kūloko kū pololei, a me nā pahu waiho pololei he hale aniani a me ke kila kila.
No laila, he aha nā mea maikaʻi o ke kila kila ma luna o ke aniani laina?
ʻO nā pahu pahu aniani, ma ka ʻaoʻao ʻē aʻe, hilinaʻi i ke aniani e hāʻawi i kahi pale ma waena o ke kila kalapona a me ka wai. Hāʻawi ʻia i ka manawa, e hoʻouka ka oxygen a me nā kinikona i loko o ka wai i ke kila a hoʻopau koke iā ia.
E pau ana ka anode i ka manawa, a i ka pau ana o ka hana, e hoomaka ana ka electrolysis e hoopau i na wahi kila i hoikeia i loko o ka pahu.
ʻO ka ʻoiaʻiʻo, ʻike pinepine ʻia ka nānā ʻana a me ka hoʻololi ʻana i nā anodes, a kahe ka pahu, e hoʻololi i ka ʻāpana holoʻokoʻa.
Ma muli o kēia piʻi ʻana o ka lōʻihi a me ka pale ʻana i ka corrosion, e ʻike pinepine ʻoe i nā pahu kila kila he mau palapala hōʻoia ʻoi aku ka lōʻihi, me kekahi mau mea hana e hāʻawi i nā palapala hōʻoia ola no nā pahu.
Loaʻa i nā pahu kila kila ka maikaʻi o ka māmā i ka hoʻohālikelike ʻia me nā pahu aniani, e maʻalahi ai ka lawe ʻana, mālama a hoʻokomo.
ʻAʻole e like me nā kīʻaha aniani, ʻoi aku ka liʻiliʻi o ka nānā ʻana o nā ipu kila kila i ka wā e hoʻouna ai, a hiki ke hōʻino ʻia ka uhi aniani i ka wā o ka hoʻouna ʻana.
Hiki i nā pahu kila kila ke kū i nā mahana wai kiʻekiʻe aʻe ma mua o nā pahu aniani, a ʻo nā mahana ma luna o 180F ʻaʻole e hōʻike i kekahi pilikia. ʻO kekahi mau pahu aniani i hoʻopaʻa ʻia e maʻalahi i ke koʻikoʻi i nā wela kiʻekiʻe, e hopena i kahi kiʻekiʻe o ka pōʻino o ke aniani.
Manaʻo ʻia e nīnau i ka mea hana pahu pahu aniani no ka mahana hana ʻoi loa i ʻōlelo ʻia.
ʻAʻohe mea kānalua ʻoi aku ka kiʻekiʻe o ke kumukūʻai mua o ka pahu kila kila ma mua o ka pahu aniani.
