Ma ke ʻano o ka wehe ʻana i ka lepo o ka ʻoihana, ʻaʻole ʻo "ka lepo kānana ʻeke" he mea kemika kikoʻī, akā he huaʻōlelo maʻamau no nā ʻāpana paʻa a pau i hoʻopaʻa ʻia e ka ʻeke kānana lepo i loko o ka ʻeke. Ke hele ka ea i ka lepo i loko o kahi ʻeke kānana cylindrical i hana ʻia me ka polyester, PPS, aniani fiber a aramid fiber ma kahi kānana makani wikiwiki o 0.5-2.0 m / min, paʻa ka lepo ma ka ʻili o ka pā ʻeke a me nā pores kūloko ma muli o nā ʻano hana like ʻole e like me ka inertial collision, screening, a me electrostatic adsorption. I ka wā lōʻihi, e hoʻokumu ʻia kahi papa o ka lepo kānana me ka "powder cake" i ka hana ʻana o ke kumu.
Na waiwai olepo kānana ʻekeʻokoʻa loa nā mea i hana ʻia e nā ʻoihana like ʻole: ʻeleʻele a spherical ka lehu lele mai loko mai o nā paila ahi ahi, me ka nui o ka 1-50 µm, aia ka SiO₂ a me Al₂O₃; ʻO ka lepo kiln ciment he alkaline a maʻalahi ke komo i ka makū a me ka agglomerate; ʻo ka pauka hao i loko o ka ʻoihana metallurgical he paʻakikī a he angular; a ʻo ka lepo i hopu ʻia i loko o nā hale kūʻai lāʻau lapaʻau a me nā meaʻai, he mau lāʻau ikaika a i ʻole nā partic starch. ʻO ka resistivity, moisture content, a me ka flammability o kēia mau lepo e hoʻoholo i ke koho ʻana i nā ʻeke kānana - anti-static, uhi, aila-hōʻoia a me ka wai a i ʻole kiʻekiʻe-mahana kūʻokoʻa pale lapaʻau, nā mea a pau e hana i ka Dust Filter Bag "e apo" i kēia mau lepo i ʻoi aku ka maikaʻi a me ka palekana.
ʻO ka hana a Dust Filter Bag: ʻaʻole wale ka "kānana"
Ka hoʻokuʻu ʻana: Ua kākau ka hapa nui o nā ʻāina i ka PM10, PM2.5 a i ʻole ka palena o ka lepo i loko o nā lula. Hiki i kahi ʻeke kānana lepo i hoʻolālā maikaʻi ʻia ke hoʻemi i ka lepo inlet o 10-50 g/Nm³ i ≤10 mg/Nm³, e hōʻoia ana ʻaʻole e hoʻopuka ka chimney i nā "deragona melemele".
Palekana i nā mea hana o lalo: Hoʻonohonoho i nā kānana ʻeke ma mua o ka lawe ʻana i ka pneumatic, hiki i nā turbines gas a i ʻole nā ʻōnaehana denitrification SCR ke pale i ka hoʻohana ʻana i ka lepo, hoʻopaʻa ʻia nā papa catalyst, a hoʻolōʻihi i ke ola o nā mea waiwai.
Hoʻihoʻi waiwai: Ma nā kaʻina hana e like me ka hoʻoheheʻe ʻana i ka metala makamae, ka pauka poʻi ʻulaʻula honua, a me nā mea electrode maikaʻi i ka pā lithium, ʻo ka lepo kānana ʻeke he huahana waiwai nui. Wehe ʻia ka lepo mai ka ʻili o ka ʻeke kānana e ka pulupulu a i ʻole ka haʻalulu mechanical, a hoʻihoʻi ʻia i ke kaʻina hana ma o ka hopper lehu a me ka conveyor wili, e ʻike ana "ka lepo i ka lepo, ke gula i ke gula".
Ka mālama ʻana i ke olakino ʻoihana: Inā ʻoi aku ka nui o ka lepo i loko o ka hale hana ma mua o 1-3 mg/m³, e loaʻa ana nā limahana i ka pneumoconiosis inā ʻike ʻia no ka manawa lōʻihi. Hoʻopaʻa ka Dust Filter Bag i ka lepo i loko o ka paipu paʻa a me ke keʻena ʻeke, e hāʻawi ana i kahi "pale lepo" ʻike ʻole ʻia no nā limahana.
E mālama i ka ikehu a me ke kaʻina hana optimization: Ua uhi ʻia ka ʻili o nā ʻeke kānana hou me ka membrane PTFE, hiki ke mālama i ka ea permeability kiʻekiʻe ma kahi ʻokoʻa haʻahaʻa haʻahaʻa (800-1200 Pa), a ua hoʻemi ʻia ka hoʻohana ʻana i ka mana o ka peʻahi e 10% -30%; i ka manawa like, hiki ke hoʻopili ʻia ka hōʻailona ʻokoʻa paʻa paʻa me ka peʻahi alapine ʻokoʻa a me ka ʻōnaehana hoʻomaʻemaʻe lepo naʻauao e hoʻokō ai i "ka wehe ʻana i ka lepo ma ke koi".
Mai ka "lehu" i ka "waiwai": ka hopena o ka lepo kānana ʻeke
ʻO ka hopu wale nō ka hana mua, a ʻo ka mālama ʻana ma hope e hoʻoholo i kona hopena hope. Hoʻohui hou nā mea kanu sima i ka lepo kiln i nā mea maka; Ke kūʻai aku nei nā mea mana wela i ka lehu lele i nā mea kanu hoʻoheheʻe ʻia e like me nā mea hoʻohui mineral; Hoʻouna nā mea hoʻoheheʻe metala laʻa i ka lepo ʻeke i hoʻonui ʻia me ka indium a me ka germanium i nā hale hana hydrometallurgical. Hiki ke ʻōlelo ʻia ʻaʻole he pale fiber wale nō ka Dust Filter Bag, akā ʻo ia hoʻi he "source sorter".
ʻO ka lepo kānana ʻeke ʻo ia nā ʻāpana "hoʻokuʻu ʻia" i ke kaʻina hana ʻoihana, a ʻo ka Dust Filter Bag ka "puka kiaʻi" e hāʻawi iā lākou i ke ola ʻelua. Ma o ka nani o ka fiber structure, surface engineering a me ka hoʻomaʻemaʻe akamai, ʻaʻole pale wale ka ʻeke kānana i ka lani uliuli a me nā ao keʻokeʻo, akā pale pū nō hoʻi i ke olakino o nā limahana a me nā waiwai ʻoihana. Ke hoʻokuʻu ʻia ka lepo i ka lehu ma waho o ka pā ʻeke a hoʻāla hou ʻia ma ke ʻano he kumu i loko o ka puʻu lehu, hoʻomaopopo maoli mākou i ke ʻano piha o ka Dust Filter Bag: ʻaʻole ia he mea kānana wale nō, akā ʻo ke kumu hoʻomaka o ka hoʻokele waiwai.
