He ʻāpana koʻikoʻi ka wili lanahu o ka ʻōnaehana pulverizing a me kahi mea hana mana kōkua koʻikoʻi i ka hale mana. ʻO kāna hana nui ʻo ka uhaʻi a wili i ka lanahu i loko o ka lanahu pulverized no ka hoʻolako ʻana i nā lako boiler, e pili pono ana kāna hoʻonohonoho i ka palekana a me ka hoʻokele waiwai o ka ʻāpana. No ka mea, ʻokoʻa loa ka hoʻololi ʻana o nā wili lanahu like ʻole i nā ʻano lanahu like ʻole, i hui pū ʻia me ke kūlana maoli o ka hāʻawi like ʻole ʻana o nā huahana lanahu ma Kina, e pili pono ana ka maikaʻi o nā huahana lanahu i ka hoʻokele waiwai o ka ʻōnaehana pulverizing. No laila, pehea e koho ʻia ai nā mea hana wili lanahu?Mīkini HCMma ke ʻano he mea hana wili lanahu, e hoʻolauna i ke kumu o ka koho wili lanahu. Nui nā ʻano o ka wili lanahu, e like me ka wikiwiki o ka wili ʻana i nā ʻāpana hana o ke koho ʻana i nā mea hana lānahu e hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻano, ʻo ia hoʻi: ka wili lanahu haʻahaʻa, ka wili lanahu waena a me ka wili lanahu kiʻekiʻe. Ma lalo iho nei e hoʻolauna i ke koho ʻana o kēia mau mea wili lanahu ʻekolu.
Koho 1 nā mea hana wili lanahu: wili lanahu haʻahaʻa
ʻO ka ʻelele maʻamau o ka wili lanahu haʻahaʻa ka wili pōleʻa. ʻO ke kumu hana ʻo ia: ʻo ka mīkini mana kiʻekiʻe ma o ka pahu pahu e hoʻokele i kēia wili pōʻai pōʻai kaumaha, ua hoʻohuli ʻia ka pōpō kila ma ka maʻalahi i kahi kiʻekiʻe a laila hāʻule i lalo, ma o ka hopena o ka pōpō kila ma ka lanahu a ma waena o ka pōpō kila, ma waena o ka pōpō kila a me ka pā kiaʻi, ua lepo ka lanahu. Hoʻokaʻawale ʻia ka lanahu i hoʻokaʻawale ʻole ʻia i ka wā e kahe ai ma ka mea hoʻokaʻawale pauda ma ke kua o ka wili kinipopo, a laila hoʻouna ʻia i ka pā pōʻai mai ka paipu pauda hoʻihoʻi no ka wili hou ʻana. Ma waho aʻe o ka lawe ʻana i ka pauka lanahu, hoʻokani pū ka ea wela i ka hana o ka hoʻomaloʻo ʻana i ka lanahu. No laila, kapa ʻia ka ea wela i ka desiccant ma ka ʻōnaehana pauka. Loaʻa i ka huahana nā hiʻohiʻona o ka manawa hana lōʻihi, mālama maʻalahi, hoʻopuka paʻa a me ka maikaʻi, ka nui o ka mālama ʻana, ka pane wikiwiki, ka maʻalahi o ka hana, haʻahaʻa haʻahaʻa ea-lanahu, mālama i ka mīkini lanahu kaʻawale, ākea ākea o ka lanahu wili a pēlā aku. Hoʻohana nui ʻia ia no ka lanahu paʻakikī a me ka paʻakikī paʻakikī, ʻoi aku ka nui o ka lanahu me ka maʻiʻo nui a me ka waiwai abrasive ikaika. Eia nō naʻe, ʻoi aku ka nui o kēia wili pōleʻa haʻahaʻa haʻahaʻa, he nui ka hoʻohana ʻana i ka metala, noho i ka ʻāina he nui, a he kiʻekiʻe ka hoʻopukapuka mua. No laila, kūpono ka wili pōleʻa no ka hana piha piha.
ʻAno 2 lako hale wili lanahu:wili lanahu māmā
Ua ʻike ʻia ka wili lanahu kūwaho, ʻo ia ka mea i ʻike ʻia e nā ʻāpana wili i haku ʻia i ʻelua mau pūʻulu pili o ke kino wili. Hoʻopiʻi ʻia ka lanahu a hoʻoheheʻe ʻia ma waena o nā ʻili o nā kino ʻelua a ʻoki ʻia. I ka manawa like, hoʻomaloʻo ka ea wela ma o ka wili i ka lanahu a hoʻouna i ka lanahu pulverized i ka mea hoʻokaʻawale ma ka ʻaoʻao o luna o ka wili. Ma hope o ka hoʻokaʻawale ʻana, lawe ʻia ka lanahu i hoʻoheheʻe ʻia o kekahi ʻāpana nui mai ka hale wili me ke kahe ʻana o ka ea, a hoʻihoʻi ʻia ka lanahu i hoʻoheheʻe ʻia i ka wahi wili no ka wili hou ʻana. Loa'a ka pono o ka wili lanahu ma waena o nā lako pa'akikī, nā kapua'i li'ili'i, ka mālama 'ana i ka mana (ma kahi o 50% ~ 75% o ka wili kinipōpō), ka wala'au ha'aha'a, ka māmā a me ka mana o ka hana ma'alahi. Akā ʻaʻole kūpono ia no ka wili ʻana i ka lanahu paʻakikī.
Koho nā lako wili lanahu 3: ka wili lanahu kiʻekiʻe
ʻO ka wikiwiki o ka wili lanahu kiʻekiʻe he 500 ~ 1500 r / min, ka mea nui i haku ʻia me ka rotor kiʻekiʻe a me ka wili ʻana. Ka wili maʻamau a me ka wili hāmare a pēlā aku. I loko o ka wili, uaʻokiʻia ka lanahu e ka huiʻana ma waena o ka hopena kiʻekiʻe a me ka pūpū wili a me ka huiʻana ma waena o ka lanahu. ʻO kēia ʻano wili lanahu a me ka mea hoʻokaʻawale lanahu puʻupuʻu i mea holoʻokoʻa, maʻalahi ke ʻano, paʻa, haʻahaʻa ka hoʻopukapuka mua, ʻoi aku ka maikaʻi no ka wili ʻana i ka lignite moisture kiʻekiʻe a me ka mea maʻalahi, maʻalahi e wili i ka lanahu bituminous. Eia nō naʻe, no ka mea, ʻaʻole i kiʻekiʻe ka nui o ka wai o ka lanahu honua, ka mea maʻamau i hoʻohana ʻia no nā boilers puhi pololei i nā mea kanu mana, ʻaʻole pono e hoʻohana ʻia no nā papa hana hoʻoheheʻe i ka umu ahi.
ʻO nā ʻano ma luna ʻekolu o ka koho ʻana i nā mea hana wili lanahu i nā pono a me nā hemahema, i ke koho ʻana i nā lako wili lanahu, pono e noʻonoʻo i ka koho holoʻokoʻa o ka ʻōnaehana pulverizing. Hiki ke hoʻokaʻawale ʻia ka ʻōnaehana pauka i ʻelua mau ʻāpana: ʻano puhi pololei a me ke ʻano mālama waena (i ʻōlelo ʻia he ʻano mālama). I loko o ka ʻōnaehana pulverization puhi pololei, hoʻoheheʻe ʻia ka lanahu i loko o ka lanahu pulverized e kahi wili lanahu a laila puhi pololei ʻia i loko o ka umu no ka puhi ʻana. I loko o ka'ōnaehana pulverization, e mālama muaʻia ka lanahu i hoʻopaʻaʻia i loko o ka pahu lanahu, a laila e like me ka pono o ka ukana paila, e hoʻounaʻia ka lanahu i hoʻopiliʻia i ka umu ahi no ka puhiʻana e ka pulverizer. He kūpono hoʻi nā ʻōnaehana pulverizing like ʻole no nā ʻano like ʻole o ka lanahu a me ka koho ʻana i nā mea hana wili lanahu. Wahi a ka ʻōnaehana pulverization, ua hōʻuluʻulu mākou i kēia kumu no ke koho ʻana i ka wili lanahu:
(1) Steel poepoe wili i loko o ka waena waihona pahu 'ano wela ea pauda nenoaiu: hiki ke hoʻohana 'ia no ka anthracite (Vsr<9%) a komo i loko o ka ikaika ma luna o ka lanahu.
(2) ʻO ka wili pōleʻa waena o ka mālama ʻana i ka ʻōnaehana hoʻopau kinoea pauka: hoʻohana nui ʻia no ka lanahu me ka lole ikaika a me ka liʻiliʻi liʻiliʻi (Var-19% ~ 27%) lanahu bituminous.
(3) Palua-i papalua-waho kila poepoe wili pono puhi nenoaiu 22-241: no ka waena-kiʻekiʻe volatile (Vs.7-27%~40%) bituminous lanahu.
(4) Medium-mämä holo lanahu wili pololei nenoaiu: kūpono no ka wili lanahu bituminous me ka kiʻekiʻe volatile maʻiʻo (Vanr-27% ~ 40%), kiʻekiʻe moisture maʻiʻo (waho maʻamau Mp≤15%) a me ka ikaika aahu, a me ka lanahu poho poho ma lalo o ka ikaika, ka lanahu hana hoʻohūhū mea e flammable, a pulverized ka lanahu fineness halawai.
(5) Pūnaehana puhi pololei ʻana i ka mīkini pā: kūpono no ka lignite erosion wear index Ke≤3.5 a me 50 MW a ma lalo o bituminous coal unit boiler
I ke koho ʻana i nā mea hana wili lanahu, pono e noʻonoʻo ʻia e like me nā ʻano puhi ahi, ʻaʻahu a me nā ʻano pahū o ka lanahu, nā ʻano pulverization o ka wili lanahu a me nā koi o ka pulverized coal fineness, i hui pū ʻia me ke ʻano umu ahi a me ke ʻano puhi ahi o ka paila, a noʻonoʻo i ka hoʻopukapuka kālā, ka mālama ʻana a me ka pae hana o ka mana mana a me nā mea kākoʻo a me nā mea kākoʻo. nā kumu ʻē aʻe. I mea e hoʻokō ai i ka hoʻokūkū kūpono ma waena o ka pulverizing system, combustion device a me boiler furnace, e hōʻoia i ka palekana a me ka hoʻokele waiwai o ka ʻāpana. He loea ʻo HCM Machinery i ka hana ʻana i nā mea hana wili lanahu medium-speed, hana mākou i ka HLM series of medium-speed coal mill i kēia mau hiʻohiʻona:
(1) ʻO ka hoʻohana ʻana i ka roller diameter nui a me ka disk, ʻoi aku ka liʻiliʻi o ke kūpaʻa ʻana, maikaʻi nā kūlana inlet lanahu maka, pēlā e hoʻomaikaʻi ai i ka hiki ke hana, hoʻemi i ka hoʻohana ʻana i ka ikehu.
(2) maikaʻi ka hana reducer, palekana a hilinaʻi; Haʻahaʻa holo ka leo a haʻalulu; Maikaʻi ka hana sealing e hōʻoia ʻaʻole i komo ka pauka lanahu i nā ʻāpana mechanical rotating.
(3) He kūpono no ka wili ʻana i ka lanahu paʻakikī, ka ikaika wili like ʻole, ka maikaʻi wili kiʻekiʻe. Hana kūpaʻa a hilinaʻi.
(4) ʻAʻole i loaʻa ka wili MPS i nā ʻāpana friction maikaʻi ʻole, a liʻiliʻi ka lole metala. Inā loaʻa iā ʻoe ka pilikia o ke koho ʻana i nā lako wili lanahu, e hoʻokipa e hoʻokaʻaʻikeMīkini HCM for the basis of coal mill selection, contact information:hcmkt@hcmilling.com
