He hihia noi no ka hale mana nona iho ma kekahi ʻoihana pepa ma Fujian

ʻO kekahi ʻoihana ʻoihana pepa i kaupalena ʻia ma Fujian Province kekahi o nā ʻoihana hana pepa nui loa ma ka panalāʻau a me kahi ʻoihana panalāʻau koʻikoʻi e hoʻohui ana i ka hana pepa nui me ka hui pū ʻana o ka wela a me ka mana. ʻO ka nui o ke kūkulu ʻia ʻana o ka pāhana he ʻehā pūʻulu o "630 t/h kiʻekiʻe-mehana a kiʻekiʻe-peʻe multi-fuel circulating fluidized bed boilers + 80 MW back-pressure steam turbines + 80 MW generators," me hoʻokahi boiler e lawelawe ana ma ke ʻano he backup unit. Hoʻokō ʻia ka pāhana i ʻelua mau ʻanuʻu: ʻo ka papa mua he ʻekolu pūʻulu o ka hoʻonohonoho ʻana o nā mea hana i haʻi ʻia ma mua, aʻo ka ʻāpana ʻelua e hoʻohui i kahi hoʻonohonoho hou.

He kuleana koʻikoʻi ka nānā ʻana i ka maikaʻi o ka wai i ka nānā ʻana i ka paila, no ka mea, pili pono ka maikaʻi o ka wai i ka hana ʻana o ka paila. ʻO ka maikaʻi ʻole o ka wai hiki ke alakaʻi i ka hiki ʻole o ka hana, ka pōʻino o nā lako, a me nā pōʻino palekana no nā limahana. ʻO ka hoʻokō ʻana i nā mea hana nānā wai maikaʻi ma ka pūnaewele e hōʻemi nui i ka pilikia o nā hanana palekana pili i ka boiler, e hōʻoiaʻiʻo ai i ka hana palekana a paʻa o ka ʻōnaehana boiler.

Ua hoʻohana ka hui i nā mea hana loiloi maikaʻi o ka wai a me nā mea ʻike like i hana ʻia e BOQU. Ma ka nānā ʻana i nā ʻāpana e like me pH, conductivity, dissolved oxygen, silicate, phosphate, a me nā ion sodium, e hōʻoia i ka hana palekana a paʻa o ka paila, hoʻonui i ke ola lawelawe o nā mea hana, a hōʻoia i ka maikaʻi o ka mahu.

Waiwai pH: Pono e mālama ʻia ka pH o ka wai paila i loko o kahi kikoʻī (maʻamau 9-11). Inā haʻahaʻa loa (acidic), e ʻino ia i nā ʻāpana metala o ka paila (e like me nā paipu kila a me nā pahu mahu). Inā kiʻekiʻe loa (ka ikaika alkaline), hiki ke hāʻule ke kiʻi pale ma ka ʻili metala, e alakaʻi ana i ka ʻino alkaline. Hiki i ka pH kūpono ke keʻakeʻa i ka hopena corrosive o ke kalapona kalapona manuahi i loko o ka wai a hoʻemi i ka pilikia o ka paipu scaling.

Conductivity: Hōʻike ka conductivity i ka huina o nā ion dissolved i ka wai. ʻO ke kiʻekiʻe o ka waiwai, ʻoi aku ka nui o nā haumia (e like me nā paʻakai) i loko o ka wai. Hiki ke alakaʻi i ka hoʻokalakupua kiʻekiʻe i ka scaling boiler, accelerated corrosion, a hiki ke hoʻopilikia i ka maikaʻi o ka mahu (e like me ka lawe ʻana i nā paʻakai), e hōʻemi i ka pono wela, a hiki i nā hanana palekana e like me ka hū ʻana o ka paipu.

ʻO ka oxygen i hoʻoheheʻe ʻia: ʻO ka oxygen i hoʻoheheʻe ʻia i loko o ka wai ke kumu nui o ka hoʻoheheʻe ʻana o ka oxygen o nā metala paila, ʻoi aku hoʻi i nā mea economizers a me nā pā i hoʻoluʻu wai. Hiki iā ia ke alakaʻi i ka lua a me ka lahilahi o ka ʻili metala, a i nā hihia koʻikoʻi, leakage mea hana. Pono e hoʻomalu i ka oxygen dissolved ma kahi haʻahaʻa haʻahaʻa (maʻamau ≤ 0.05 mg / L) ma o ka deaeration treatment (e like me ka thermal deaeration a me ka chemical deaeration).

Silicate: Hiki ke hoʻoheheʻe ʻia ka silicate me ka mahu ma lalo o ke kiʻekiʻe o ka wela a me ke kaomi, e waiho ana ma luna o nā lau turbine e hana i ka silicate scale, e hōʻemi ana i ka pono turbine a pili pū i kāna hana palekana. Hiki i ka nānā ʻana i ka silicate ke hoʻomalu i ka ʻike silicate i loko o ka wai paila, e hōʻoia i ka maikaʻi o ka mahu, a pale i ka scaling turbine.

Aʻa Phosphate: ʻO ka hoʻohui ʻana i nā paʻakai phosphate (e like me ka trisodium phosphate) i loko o ka wai paila hiki ke hana me nā ion calcium a me ka magnesium e hana ai i nā paʻakai phosphate palupalu, e pale ana i ka hoʻokumu ʻia ʻana o ka unahi paʻakikī (ʻo ia hoʻi, "ka lāʻau pale pale phosphate"). ʻO ka nānā ʻana i ka neʻe ʻana o ke aʻa phosphate e hōʻoia i ka noho ʻana i loko o kahi ākea kūpono (maʻamau 5-15 mg/L). Hiki i nā pae kiʻekiʻe ke alakaʻi i ke aʻa phosphate e lawe ʻia e ka mahu, aʻo nā pae haʻahaʻa loa e hiki ʻole ke pale pono i ka hoʻokumu ʻana i ka unahi.

ʻAiona Sodium: ʻO nā ion sodium ka mea maʻamau i hoʻokaʻawale ʻia i ka paʻakai i loko o ka wai, a hiki i kā lākou ʻike ke hōʻike pololei ʻole i ka degere koʻikoʻi o ka wai paila a me ke kūlana o ka paʻakai i lawe ʻia e ka mahu. Inā kiʻekiʻe loa ka ʻike ʻana o nā ion sodium, e hōʻike ana i ka paʻa ʻana o ka wai paila, hiki ke hoʻoulu i ka scaling a me ka corrosion; ʻO ka nui o nā ion sodium i loko o ka mahu e alakaʻi pū i ka hōʻiliʻili paʻakai i ka turbine mahu, e pili ana i ka hana o nā mea hana.
