Kampani yokonza chakudya yokonza madzi otayira mafuta ambiri

I. Mbiri ya polojekiti
Kampani yokonza chakudya yapakatikati imayang'ana kwambiri pa kukonza chakudya chokazinga ndi nyama, ndipo imapanga madzi ambiri otayira mafuta ambiri popanga, omwe ali ndi zinthu zoipitsa monga zotsalira za chakudya, mafuta a nyama ndi zomera komanso mapuloteni. Ubwino wa madzi otayira umasinthasintha kwambiri, kuchuluka kwa mafuta kumakhala kwakukulu, ndipo kutuluka mwachindunji kumakhala kosavuta kuyambitsa kutsekeka kwa mapaipi ndi kusungunuka kwa madzi. Malinga ndi kuwerengera kwa sikelo yopangira ya kampaniyo, kutuluka kwa madzi otayira ndi 2.5m³/h. Kuti akwaniritse zofunikira zoteteza chilengedwe ndikupeza chitukuko chokhazikika, mabizinesi ayenera kupanga njira yothandiza komanso yokhazikika yosamalira madzi otayira yokhala ndi malo ochepa kuti atsimikizire kuti madzi otayira afika pamlingo woyenera ndikuchepetsa kutaya kwa matope.

II. Zinthu zazikulu zomwe makasitomala amakumana nazo
Mafuta ambiri ndi ovuta kuthana nawo: mafuta omwe ali m'madzi otayira ndi ≥80mg/L, ndipo njira yochiritsira yachikhalidwe imakhala ndi zotsatira zoyipa pakulekanitsa mafuta osungunuka, zomwe zimapangitsa kuti zida zochiritsira zitseke, kusagwira ntchito bwino, komanso ndalama zambiri zosamalira.

Mphamvu yogwiritsira ntchito zida zoyambirira si yokwanira: zida zosavuta zomwe zilipo sizingakwaniritse kufunikira kwa kutulutsa madzi kwa 2.5m³/h, ndipo khalidwe la madzi otuluka limasintha kwambiri, zomwe zimapangitsa kuti pakhale chiopsezo chopitirira muyezo woteteza chilengedwe.

Zoletsa ziwiri za malo otayira ndi kutaya: fakitaleyi ili ndi malo ochepa, omwe amafunikira njira yochepetsera komanso yothandiza, komanso kuthetsa vuto la kutaya matope kuti apewe kuipitsa kwina.

3. Mayankho Opangidwa Mwamakonda
Malinga ndi makhalidwe a madzi otayira mafuta ambiri komanso zosowa zenizeni za makasitomala, njira yophatikizira yothandizira "kuchiza msanga + kutsekeka kwa madzi + kusefa kwa diaphragm pressure ndi kutaya madzi m'thupi" idapangidwa, ndipo njira yoyezera ndi kuchotsa madzi m'matope m'mafakitale imakonzedwa bwino kuti ichotse mafuta bwino komanso kuti igwire ntchito bwino.

1. Kuyenda kwa njira

Mu gawo lokonzekera, madzi otayira amayamba kudutsa mu gridi yamakina kuti achotse tinthu tambiri ta chakudya, kenako amalowa mumsampha wa mafuta owonjezera, ndipo mfundo yolekanitsa mphamvu yokoka imagwiritsidwa ntchito kuchotsa mafuta otsetsereka (kuchuluka kochotsa ≥60%), zomwe zimachepetsa kwambiri katundu wotsatira wa mankhwala.

Gawo la kuuma ndi kuyandama: Pambuyo pokonza madzi asanayambe, madzi otayira amalowa mu thanki yolumikizirana, ndipo PAC (polyaluminum chloride) ndi PAM (polyacrylamide) zimawonjezedwanso kudzera mu pampu yoyezera yolondola. PAC imawononga momwe mafuta amakhalira, PAM imalimbikitsa kuyandama kwa flocs, ndikupanga flocs yokhala ndi mafuta yomwe ndi yosavuta kuyandama, ndikuzindikira kulekanitsa bwino kwa mafuta, madzi ndi magawo atatu olimba.

Gawo lolekanitsa madzi olimba ndi madzi ndi kutaya madzi: madzi otayidwa akamaundana, amalowa mu thanki yosungira madzi kuti alekanitse matope ndi madzi, ndipo supernatant imatulutsidwa pamlingo woyenera. Madzi otayidwa omwe ali pansi amapopedwa mu makina osindikizira a diaphragm filter, ndipo chinyezi cha matopewo chimachepetsedwa kufika pansi pa 60% chifukwa cha kutulutsa kwa diaphragm pressure komanso kutaya madzi, zomwe zimapangitsa kuti pakhale matope olimba kuti anyamulidwe ndi kutayidwa kunja. Filtrate ya fyuluta yotenthetsera madzi imabwezeretsedwa ku chipangizo choyeretsera madzi kuti madzi otayidwa atsekedwe bwino mu ndondomeko yonse.

2. Zipangizo zofunika ndi magawo ogwiritsira ntchito

Pakatikati pa makina opangira zinthu pamakhala chipangizo cholumikizirana chothandizira kupopera madzi chomwe chimagwira ntchito yokwana 2.5m³/h, komanso chosindikizira cha 30㎡ diaphragm filter.

Mlingo wa PAC: 50-80mg/L, Mlingo wa PAM: 3-5mg/L, malinga ndi kusintha kwa khalidwe la madzi nthawi yeniyeni, kuti zitsimikizire zotsatira zabwino kwambiri za chithandizo;

Dongosololi lili ndi dongosolo lanzeru lowongolera kuti ligwire ntchito yokhayokha ya mankhwala, kuchotsa matope ndi maulalo ena, ndikuchepetsa mphamvu ya ntchito yamanja.

Iv. Zotsatira za kukhazikitsa polojekiti
Ubwino wa madzi otuluka m'thupi ndi wokhazikika komanso wofanana ndi muyezo: pambuyo poti dongosololi layamba kugwira ntchito, kuchuluka kwa mafuta m'madzi otuluka m'thupi kumachepa kufika pa 5mg/L, ndipo zizindikiro zina zimagwirizana ndi miyezo yotulutsira madzi m'thupi;

Zotsatira zake zochepetsera matope ndi zodabwitsa: makina osindikizira a diaphragm amachepetsa chinyezi cha matopewo kufika pa 60%, ndipo kuchuluka kwa matopewo kumachepetsedwa ndi pafupifupi 70%, zomwe zimachepetsa kwambiri mtengo wotayira;

Kugwira ntchito ndi kukonza kosavuta: kapangidwe kophatikizidwa kamaphimba malo ang'onoang'ono, kuchuluka kwa zochita zokha, ntchito yochepa yokonza tsiku ndi tsiku, kugwira ntchito kokhazikika komanso kodalirika kwa nthawi yayitali.

V. Chidule cha nkhani
Kudzera mu njira yokonzedwa bwino yokonzekera, kupopera madzi ndi kupopera madzi kuchokera ku diaphragm, vutoli limathetsa mavuto a kukonza madzi otayira mafuta ambiri m'makampani opanga chakudya. Dongosololi lili ndi mphamvu zambiri, kukhazikika komanso kufupika, zomwe sizimangotsimikizira kuti madzi otayira afika pamlingo woyenera, komanso zimathandiza kuchepetsa ndi kutaya zinthu zotayira, kupatsa makasitomala njira zotetezera zachilengedwe komanso zachuma.
