一.Introduction of application principle

Munguva yekupenda, chiyero chekuputira chepende chinongova makumi mana kusvika makumi matanhatu muzana, uye inopfuura hafu yepende inonyura mumhepo kuita mhute yekupfapfaidza, ichisvibisa zvakanyanya mhepo yakatenderedza uye nharaunda. Kuti unyatso kuchengetedza zvakatipoteredza uye kuchenesa nzvimbo yekuvaka, iyo inotenderera yemvura yemvura yekupfapfaidza dumba inowanzoshandiswa muindasitiri yekupenda kubata mhute yependi yakanyanyisa. Kuti uchengetedze kushanda kwenzvimbo yekupfapfaidza, kuvandudza nzvimbo yekushanda yekupenda, uye kuita kuti sisitimu yekuchenesa ishande zvakajairwa, zvishoma zvemakemikari zvinhu zvinofanirwa kuwedzerwa uye kuchengetedzwa mumvura inotenderera, inowanzozivikanwa sependi mist coagulants. Inogona kubata nependi zvimedu zvakabatwa nemvura, uye yobva yaita nayo uye ichiita kuti irege kugadzikana uye disstick, iunganidze mune flocculant ine imwe particle size, inonzi paint slag, uye yakaparadzana kubva mumvura, kuitira kuti kutenderera kwemvura kugone kushandiswa. kwenguva refu. Paint mhute coagulants inonyanya kusanganisira yakasimba alkali dispersing type, condensation adsorption type, mvura-based pendi mhute condensation type, etc. Mhando dziri pamusoro pezvigadzirwa zvinogona kuita kuti pendi idistick uye inyunguduke nenzira dzinotevera: ita mhute yepende saponification, kubvisa viscosity yayo. , gadzira sipo isina kunyungudika yealkali, yakaparadzirwa mumvura; Panguva imwecheteyo, mhute yepende inodzorwa nekudzikisa mutero weiyo yekunze mhute yepende. Izvo zvimedu zvakanyungudutswa zvinosungirirwa mu flocculant nekudhumhana, uye ipapo iyo polymer flocculant inoshambadzirwa uye yakabhurwa kuita yakakura flocculant.

二.Maitiro ekutonga nemazvo maitiro ependi mhute flocculant

Mhedzisiro yependi mhute coagulant inowanzo tongwa kubva kune slag, mvura, furo, kunhuwa uye zvichingodaro.
(1) Paint slag: Iyo viscosity inofanira kunge idiki sezvinobvira, uye yakazara chitarisiko chiyero chinofanira kunge chiri 3 kusvika 4 (pendi slag is granular kana jecha rakanaka).
(2) Mvura: muEisenmann side inoyerera slagging mudziyo, usati waisa slagging uye usati wawedzera mumiririri B, pendi inofanira kunge yakapararira zvakanyanya turbidity mvura, uye mvura mushure mekuwedzera mumiriri B inofanira kujeka sezvinobvira, uye chiyero chemhando yemvura chinofanira kunge chiripo. kuve giredhi 3 (zvishoma turbid).
(3) Foam: kureba kwefuro mudziva kunofanira kunge kwakakodzera, uye hakufaniri kunge kwakakwirira kudarika urefu hwehuputi hunogadzirwa nemvura ine mishonga chete pasi pemamiriro akafanana. Iyo furo yakakwira zvakanyanya, zvichiratidza kuti kupatsanurwa kwependi nemvura hakuna kunaka.
(4) Kunhuwa: Panguva yakatarwa yekushanda, hapana kunhuhwirira kunooneka kusingafadzi kunofanira kugadzirwa, izvo zvinoratidza kuti hurongwa hwemvura hune njodzi dzehutachiona senge mildew uye mabhakitiriya, uye zvinogonawo kukonzerwa nekuparadzaniswa kwakashata kwepende nemvura, asi kushandiswa. yependi mhute coagulants haizobudisi kunhuhwirira kunogumbura, uye akawanda pendi mhute coagulants inowedzerwa kune antibacterial agents.

三.Zvinhu zvinofurira mashandiro emhute yependi inoyerera

(1) Mhando dzepende. Kunyangwe pasina kuwirirana kwakawanikwa pakati pemhando yeresin uye mhedzisiro yekushandiswa, inozivikanwa kuti pendi mhute coagulants inonzwa kune polarity ye resin. Pendi mhute coagulants akasiyana polarity uye hydrophilicity inofanira kushandiswa zvakateerana kune pendi dze polarity dzakasiyana.

(2) PH kukosha kana alkalinity. Izvo zvave zvichizivikanwa kuti chaiyo alkalinity kana pH inobatsira pakubvisa pendi. Iyo pH kukosha kwakanyanyisa, pendi inoparadzwa kune yakagadzikana particles yakapararira mumvura yakaoma kuyerera, yakaderera haigone kuparadzwa zvachose. Iyo general control ndeye 9.0, uye kutonga kwakakosha zvakanyanya mukushanda kwekutenderera kwemvura.

(3) pendi dumba maitiro uye pendi slag post-kurapa maitiro. Iyo inowanzoshandiswa kupfapfaidza pendi yekamuri maitiro anonyanya kusanganisira washing mhando, mvura keteni mhando, mvura keteni - washing mhando, mvura swirl mhando, Venturi mhando uye dzimwe mhando, uye anowanzoshandiswa slag kubvisa nzira dzinonyanya kusanganisira scraper ndiro, centrifugal mhando, etc. The kupfapfaidza pendi yekamuri maitiro, kutenderera kuyerera kwemvura mwero, velocity, uye nzira yekubvisa slag ichakanganisa mashandisiro ekushandisa.

(4) hydrochemical factors. Zvisina kuchena mumvura, zvakadai sekuoma, zvichakanganisa ukuru hwepende yekuparadzira zvimedu, nokudaro kukanganisa kurasikirwa kweviscosity, saka kuoma kunofanira kunge kuduku sezvinobvira. Hutsvina hwakaunzwa mukupfapfaidza pendi maitiro, senge zvinonyungudutsa, kunyanya zvisiri-polar zvinonyungudutsa, zvinogona kuderedza zvakanyanya kunyudza kwemvura kupenda mhute.

(5) Dose uye dosing nzira yepende mhute coagulant. Kana iyo dosi yakanyanya kudiki, iyo condensation mhedzisiro haina kunaka, uye kana yakanyanya kukura, ine dispersion effect uye haiburitse condensation. Yakasiyana yekupfapfaidza dumba rekunyudza pendi maitiro anoda akasiyana akanyanya dosing nzira, dzinoda kuongororwa nekutemerwa mukushandiswa chaiko.

(6) Microbial factors. Iko kusanganiswa kwezvinhu zvakasikwa mumvura inotenderera yakakwirira kwazvo, uye mamiriro ekushanda emvura inotenderera akakodzera kubereka uye kukura kwe microorganisms. Kana ikasanyatsodzorwa, kuberekeswa kwema microorganisms kuchava nechakaipa pakushandiswa kwependi mhute coagulants. Bactericidal kana bacteriostatic agents vanofanira kuwedzerwa nguva dzose kana tembiricha yakakwira.
