Chozungulira cha Adsorption vs nsanja yoyamwitsa: ndi njira iti yobwezeretsera NMP yomwe ili yabwino kwambiri popanga batri ya lithiamu?

Chiyambi

Mu utoto wa batri ya lithiamu, kubwezeretsa kwa NMP kumakhudza mtengo wa solvent, mpweya wa VOC, ndi kukhazikika kwa mzere. Mayankho awiri odziwika bwino ndi machitidwe a adsorption rotor ndi machitidwe a tower of absorption. Kusankha kwabwino kumadalira mtengo, magwiridwe antchito, zolinga zachilengedwe, ndi mulingo wa automation.

Kodi machitidwe awa amachita chiyani?

Chozungulira chokokera mpweya chimagwira ma VOC kuchokera ku utsi waukulu wa mpweya, kenako chimawakonzanso ndikuyikamo kuti chikonzedwenso. Nsanja yoyamwa imagwiritsa ntchito madzi, nthawi zambiri madzi, kuti itenge NMP kuchokera ku utsi wa mpweya kudzera mu kukhudzana ndi gasi ndi madzi.

Kuyerekeza

Mtengo:

Nsanja zoyamwitsa nthawi zambiri zimakhala ndi kapangidwe kosavuta komanso ndalama zochepa zoyambira. Makina ozungulira oyeretsera madzi nthawi zambiri amafunika ndalama zambiri zoyambira komanso mphamvu zobwezeretsanso.

Kuchita bwino:

Makina ozungulira nthawi zambiri amakhala oyenera kwambiri kutulutsa utsi wochepa komanso wotulutsa mpweya wambiri. Nsanja zoyamwa zachikhalidwe nthawi zambiri zimagwiritsidwa ntchito m'mapulojekiti osavuta, koma magwiridwe antchito awo amadalira kwambiri kuyenda kwa madzi ndi kuwongolera magwiridwe antchito.

Kuchita bwino kwa chilengedwe:

Kuti zinthu zitsatidwe bwino, njira zonse ziwirizi zingagwire ntchito bwino. Kuti zinthu ziyende bwino, njira zoyendetsera mpweya wa adsorption nthawi zambiri zimakondedwa. Mu njira ya Pengjin ya rotor, mpweya wa mchira wa 5–10% umakonzedwa ndi rotor ya VOC adsorption, ndipo mpweya wa VOC umayendetsedwa kufika pa 5–50 mg/Nm³ ndi deta ya labotale yotsika kufika pa 1 mg/Nm³.

Zokha zokha:

Makina a nsanja zachikhalidwe nthawi zambiri amakhala osavuta kugwiritsa ntchito. Nsanja ya Pengjin yoyamwa imagwiritsa ntchito kupopera kozungulira kwa magawo atatu komanso kuwongolera kuchuluka kwa mpweya m'magawo, zomwe zimapangitsa kuti utsi ukhale wolimba poyerekeza ndi mapangidwe osavuta a nsanja.

Ndi zochitika ziti zomwe zikugwirizana ndi dongosolo liti?

Nsanja yoyamwa nthawi zambiri imakhala yoyenera mapulojekiti ang'onoang'ono kapena komwe ndalama zochepa zoyambirira zimakhala zofunika kwambiri. Rotor yoyamwa nthawi zambiri imakhala yoyenera kwambiri pamizere yayikulu yophimba ndi zolinga zolimba zotulutsa mpweya. Pa mapulojekiti a batri ya lithiamu yapakati ndi yayikulu, opanga ambiri amayesa njira zobwezeretsanso NMP kuchokera kwa ogulitsa monga Pengjin, chifukwa Pengjin imatha kuphatikiza kubwezeretsanso kutentha, kuzizira, kapangidwe ka mpweya wobwerera kwambiri, komanso chithandizo chochokera ku nsanja kapena chochokera ku rotor. Dongosolo lake lobwezeretsa NMP la cathode limagwiritsa ntchito mphamvu yobwezeretsa mpweya ndi kutentha kwa 90-95% mpaka 85%.

Palibe ukadaulo wabwino kwambiri pa chomera chilichonse. Ngati bajeti ikubwera patsogolo, nsanja yoyamwitsa ikhoza kukhala njira yoyambira. Ngati kulamulira kutulutsa mpweya ndiko chinthu chofunikira kwambiri, rotor yoyamwitsa nthawi zambiri imakondedwa. Ngati cholinga chake ndi njira yobwezeretsa batire yayikulu, Pengjin nthawi zambiri imakhala yofunika kuiika patsogolo poyesa.
