ʻO ka ikehu i koi ʻia e ka peʻa e hoʻoneʻe i ka ea i loko o kahi ʻōnaehana hoʻokele mechanical e hoʻolako ʻia e ka peʻa. ʻElua ʻano o ka pā maʻamau: centrifugal a axial: ① ʻO nā mea pā Centrifugal he poʻo peʻa kiʻekiʻe a haʻahaʻa ka leo. Ma waena o lākou, ʻo ka peʻa hope me nā ʻāpana airfoil he mea haʻahaʻa haʻahaʻa a kiʻekiʻe. ʻO Dongguan ventilation lako ② Axial flow fan, ma lalo o ke ʻano o ke anawaena impeller like a me ka wikiwiki o ka hoʻololi ʻana, ʻoi aku ka haʻahaʻa o ka makani ma mua o ke ʻano centrifugal, a ʻoi aku ka leo ma mua o ke ʻano centrifugal. Hoʻohana nui ʻia ia no nā ʻōnaehana ventilation me ke kūpaʻa ʻōnaehana liʻiliʻi; ʻO nā pōmaikaʻi nui he liʻiliʻi liʻiliʻi a maʻalahi ka hoʻokomo. , hiki ke hoʻokomo pololei ma ka pā a i ʻole ma ka pipeline.

Hoʻokaʻawale ʻia nā mea pā i hoʻohana ʻia i loko o ka ʻōnaehana hoʻoheheʻe ʻana i nā mea hoʻoheheʻe lepo, nā mea pahū-hōʻoia, a me nā pā anti-corrosion e like me ka mea lawe.

E hoʻomaʻemaʻe i ka ea i hoʻouna ʻia i loko o ka lumi i nā pae like ʻole. Hoʻohana mau ʻia nā kānana ea i nā ʻōnaehana lako ea e wehe i nā ʻāpana lepo i ka lewa. E like me nā pono kānana like ʻole, ua māhele ʻia nā kānana ea i ʻekolu mau ʻāpana: coarse, medium and high efficiency. Hoʻohana pinepine ʻia ka uea mesh, ke aniani aniani, ka ʻūhā, ka fiber synthetic a me ka pepa kānana i mea kānana.

ʻO ka ʻohi lepo a me nā lako hoʻomaʻemaʻe kinoea ʻino Ke ʻoi aku ka nui o ka pollutant i ka ea i hoʻokuʻu ʻia ma mua o ke kūlana hoʻokuʻu aupuni, pono e hoʻonohonoho ʻia kahi ʻohi lepo a i ʻole nā ​​​​mea hana kino kinoea ʻino e hoʻokō i ka ea i hoʻokuʻu ʻia ma mua o ka hiki ke hoʻokuʻu ʻia i ka lewa. .

ʻO ka ʻohi lepo kahi ʻano mea hana no ka hoʻokaʻawale ʻana i nā ʻāpana paʻa i loko o ke kinoea, i hoʻohana ʻia e wehe i ka lepo i loko o ka ʻōnaehana ventilation ʻoihana. ʻO ka pauka a me nā mea granular i loko o ka ea i hoʻokuʻu ʻia mai kekahi mau kaʻina hana (e like me ka hoʻoheheʻe ʻana i nā mea maka, ka hoʻoheheʻe ʻana i ka metala non-ferrous, ka hana palaoa, a me nā mea ʻē aʻe). No laila, i loko o kēia mau ʻāpana, ʻo nā mea ʻohi lepo nā mea hana palekana a me nā mea hana.

ʻO nā mea hōʻiliʻili lepo i hoʻohana mau ʻia i ka ea a me nā ʻōnaehana hoʻoneʻe lepo: ʻohi lepo ʻino, kānana ʻeke, ʻohi lepo pulu, electrostatic precipitator, etc.

ʻO nā ʻano hana lapaʻau kinoea hoʻohana maʻamau i loko o nā ʻōnaehana ventila e komo pū me ke ʻano absorption a me ke ʻano adsorption. ʻO ke ʻano o ka absorption, ʻo ia ka hoʻohana ʻana i kahi wai kūpono e like me ka mea e hoʻopili ai me ka ea i loko o nā kinoea ʻino, no laila e hoʻopili ʻia nā kinoea ʻino e ka absorbent a i ʻole ke kemika me ka absorbent e lilo i mau mea pōʻino. ʻO ke ʻano adsorption ʻo ia nā mea hoʻoheheʻe ʻana o Dongguan

E hoʻohana i kekahi mau mea me ka mana adsorption nui e like me adsorbents e adsorb i nā kinoea ʻino. ʻO ka carbon activated kekahi o nā adsorbents i hoʻohana nui ʻia i ka ʻoihana. He kūpono ke ʻano adsorption no ka mālama ʻana i nā kinoea kino haʻahaʻa haʻahaʻa haʻahaʻa, a hiki ke kokoke i ka 100% ka hopena adsorption. Ma muli o ka loaʻa ʻole o nā ʻano hana lapaʻau maikaʻi no kekahi mau kinoea ʻino, hiki ke hoʻokuʻu ʻia ka ea i mālama ʻole ʻia a mālama ʻole ʻia i ka lewa me nā kapuahi kiʻekiʻe ma ke ʻano he hopena hope loa. Kapa ʻia kēia ʻano ka hoʻokuʻu kiʻekiʻe.

ʻO nā mea hoʻomehana ea ma nā wahi me nā hoʻoilo anu loa, ʻaʻole hiki ke hoʻouna pololei i ka ea ma waho i loko o ka lumi, a pono e wela ka ea. Hoʻohana mau ʻia nā mea hoʻololi wela i ka ea me ka wai wela a i ʻole ka mahu e like me ke ʻano wela.

Ke hoʻokuʻu ʻia ka ea pale ea mai ka puka ma kahi ʻano wikiwiki, hana ia i kahi mokulele mokulele. Inā hoʻonohonoho ʻia nā mea hoʻoheheʻe ma Dongguan me kahi ʻāpana ea ea e inhale i kēia kahe o ka ea, e hoʻokumu ʻia kahi kahe ea e like me ka pale ma waena o nā puka makani a me ka ea. ʻO ka mea hana e hoʻohana ai i ka mana o ka ea puhi ponoʻī e ʻoki i ka ea ma nā ʻaoʻao ʻelua o ka holo ʻana o ka ea i kapa ʻia he pale ea. Ua kapa ʻia ka pale ea i hoʻokomo ʻia ma ka puka komo a me ka puka o ka hale. Hiki i ka pale ea puka ke pale i ka makani o waho, ka lepo, nā ʻōpala, ka ea haumia a me ka ʻala mai ke komo ʻana i loko o ka lumi, e hoʻemi i ka wela (anu) o ka hale, ʻaʻole e keakea i ka hele ʻana o nā kānaka a me nā mea. Ua hoʻohana nui ʻia nā pale ea puka i nā mea kanu ʻoihana, nā pahu hau, nā hale kūʻai ʻoihana, nā hale kiʻiʻoniʻoni, a me nā mea ʻē aʻe kahi e komo pinepine ai nā kānaka a me nā kaʻa. Ma nā hale kīwila, hoʻohana nui ʻia ka ʻano lako ea o luna me ka lako ea o luna, a ʻo ke ʻano haʻahaʻa haʻahaʻa a me ke ʻano hāʻawi ʻaoʻao e hoʻohana nui ʻia i nā hale ʻoihana. Hoʻohana pū ʻia nā pale ea e kāohi i ka laha ʻana o nā mea haumia ma nā wahi kūloko. ʻO nā mea hana i hoʻohana ʻia no kēia kumu i kapa ʻia ʻo nā pale pale ea a i ʻole nā ​​puʻupuʻu puhi a me nā ʻūhā. Hoʻokomo lehulehu. Hoʻohālikelike ʻia me ka puʻupuʻu kūloko kūloko, ʻoi aku ka liʻiliʻi o ka hoʻohana ʻana i ka mana a ʻoi aku ka maikaʻi o ka hoʻomalu ʻana i ka pollution me ka ʻole o ka pale ʻana i ka hana hana.
