一. Nhanganyaya yemutemo wekushandisa

Munguva yekupenda, mwero wekuputira pendi i40 kusvika 60% chete, uye inopfuura hafu yependi inopararira mumhepo kuti iite mhute yekupfapfaidza, zvichisvibisa zvakanyanya mhepo nenzvimbo yakapoteredza. Kuti ichengetedze nharaunda uye ichenese nzvimbo yekuvaka, sisitimu yemvura inotenderera yewet spray booth inowanzo shandiswa muindasitiri yekupenda kubata mhute yependi yakapfapfaidzwa zvakanyanya. Kuti imba yekupfapfaidza irambe ichishanda, kunatsiridza nzvimbo yekushanda yekupenda, uye kuita kuti sisitimu yekuchenesa ishande zvakanaka, huwandu hushoma hwemakemikari hunofanirwa kuwedzerwa uye kuchengetwa mumvura inotenderera, inozivikanwa sepaint mhute coagulants. Inogona kubata nezvidimbu zvependi zvakabatwa nemvura, yobva yaita nayo yoita kuti isagare zvakanaka uye ibude, inoungana muflocculant ine saizi yakati yezvidimbu, inonzi paint slag, uye yakaparadzana nemvura, kuitira kuti kutenderera kwemvura kugone kushandiswa kwenguva yakareba. Zvinhu zvinobatanidza mhute yependi zvinonyanya kusanganisira mhando yakasimba yekupararira kwealkali, mhando yekudzikisa mhute yemvura, mhando yekudzikisa mhute yependi inobva mumvura, nezvimwewo. Mhando dzezvigadzirwa zviri pamusoro apa dzinogona kuita kuti pendi ibve uye itsvedze nenzira dzinotevera: kugadzira mhute yependi saponification, kubvisa viscosity yayo, kugadzira sipo yealkali isinganyungudike mumvura, yakapararira mumvura; Panguva imwe chete, mhute yependi inotsvedzeswa nekuderedza simba rekunze kwemhute yependi. Zvidimbu zvakatsvedzeswa zvinobatanidzwa muflocculant nekugumburana, uye ipapo flocculant yepolymer inonamirwa uye inosungirirwa kuti igadzire flocculant yakakura.

Zvimwe. Maitiro ekutonga nemazvo mhedzisiro yependi mhute flocculant

Mhedzisiro ye coagulant yependi inowanzo tariswa kubva kune slag, mvura, furo, hwema nezvimwewo.
(1) Pendi ine slag: Viscosity inofanira kunge iri diki sezvinobvira, uye chitarisiko chakazara chinofanira kunge chiri kanenge 3 kusvika 4 (pendi ine slag ine granular kana jecha rakatsetseka).
(2) Mvura: mumudziyo weEisenmann side flow slagging, usati waisa slagging uye usati waisa agent B, pendi inofanira kunge yakapararira zvakanyanya nemvura ine turbidity, uye mvura mushure mekuisa agent B inofanira kunge yakajeka sezvinobvira, uye chiyero chehunhu hwemvura chinofanira kunge chiri giredhi rechitatu (rakapfava zvishoma).
(3) Furo: kureba kwefuro mudziva kunofanira kunge kwakakodzera, uye hakufanirwe kunge kwakakwirira zvakanyanya kupfuura kureba kwefuro rinogadzirwa nemvura ine mishonga chete mumamiriro akafanana. Furo racho rakanyanya kukwira, zvichiratidza kuti pendi nemvura hazvina kunaka pakupatsanurana.
(4) Kunhuhwirira: Munguva yakatarwa yekushanda, hapana kunhuhwirira kwakajeka kunofanirwa kugadzirwa, izvo zvinoratidza kuti sisitimu yemvura ine njodzi dzehutachiona hwakadai sefungus nemabhakitiriya, uye zvinogonawo kukonzerwa nekusapatsanurwa zvakanaka kwependi nemvura, asi kushandiswa kwezvinobatanidza pendi hazvizoburitse kunhuhwirira kunotsamwisa, uye ma coagulants mazhinji epainting anowedzerwa kune zvinorwisa mabhakitiriya.

Zvimwe. Zvinhu zvinokanganisa mhedzisiro yependi mhute flocculant

(1) Mhando dzependi. Kunyangwe pasina hukama hwakawanikwa pakati perudzi rweresin nemhedzisiro yekushandiswa, zvinozivikanwa kuti macoagulants ependi anonzwa polarity yeresin. Macoagulants ependi ane polarity yakasiyana uye hydrophilicity anofanirwa kushandiswa zvakateerana kune pendi dzine polarity yakasiyana.

(2) PH kana kuti alkalinity. Zvave zvichizivikanwa kuti alkalinity chaiyo kana pH inobatsira pakubviswa kwependi. pH yakanyanya kukwira, pendi inoparadzwa kuti zvidimbu zvakagadzikana zvipararire mumvura yakaoma kuyerera, yakaderera zvakanyanya haigone kuparadzwa zvachose. Kudzora kwakajairika i9.0, uye kudzora kwakakosha zvikuru mukushanda kwemvura inotenderera.

(3) maitiro ekuisa pendi padenga uye maitiro ekuisa pendi paganda mushure mekurapwa. Maitiro ekuisa pendi paganda anowanzo shandiswa anosanganisira mhando yekuwachisa, mhando yeketeni remvura, mhando yekuwachisa keteni remvura, mhando yekuchinja kwemvura, mhando yeVenturi nedzimwe mhando, uye nzira dzekubvisa slag dzinowanzo shandiswa dzinosanganisira plate yekukwenya, mhando yecentrifugal, nezvimwewo. Maitiro ekuisa pendi paganda paganda, mwero wekuyerera kwemvura inotenderera, kumhanya, uye nzira yekubvisa slag zvinokanganisa mashandiro ekushandisa.

(4) zvinhu zvinokonzerwa ne hydrochemical. Kusachena mumvura, sekuomarara, kuchakanganisa saizi yezvidimbu zvependi zvinopararira, nokudaro zvichikanganisa kurasikirwa nekusimba, saka kuomarara kunofanira kunge kudiki sezvinobvira. Kusachena kunounzwa mukuita kwekupenda ne spray, senge zvinonyungudutsa, kunyanya zvisiri zve polar solvents, zvinogona kuderedza zvakanyanya kugona kwemvura kupinza mu fog yekupenda.

(5) Nzira yekuyera uye yekuyera ye coagulant yependi. Kana chiyero chiri chidiki, mhedzisiro yekuyera haina kunaka, uye kana yakakura zvakanyanya, ine mhedzisiro yekupararira uye haiburitse kuyera. Maitiro akasiyana ekunyudza pendi yespray booth anoda nzira dzakasiyana dzekuenzanisa, dzinofanira kuongororwa uye kusarudzwa pakushandiswa chaiko.

(6) Zvinhu zvinokonzerwa nehutachiona. Kuwanda kwezvinhu zvipenyu mumvura inotenderera kwakakwira zvikuru, uye mamiriro ekushanda kwemvura inotenderera akakodzera kubereka nekukura kwehutachiona. Kana zvikasadzorwa nokungwarira, kubereka kwehutachiona kuchava nemhedzisiro yakaipa pakushandiswa kwemishonga inorwisa mabhakitiriya kana kuti inouraya utachiona inofanira kuwedzerwa nguva nenguva kana tembiricha yakakwira.
