Kune matatu masisitimu ekutenderera mumaindasitiri efiriji mayuniti, uye matambudziko ekuyera anowanzo kuitika mune akasiyana masisitimu ekutenderera, akadai sefiriji kutenderera system, mvura yekutenderera system, uye yemagetsi control circulation system. Masisitimu akasiyana ekutenderera anoda kubatana kwakanyarara kuti uwane chinangwa chebasa rakagadzikana.
Naizvozvo, zvinodikanwa kuchengetedza yega yega system mukati meyakajairika yekushanda. Kunyangwe kuita kweakasiyana siyana anogadzirwa muindasitiri efiriji michina yakagadzikana, kana iyo inodiwa gadziriso uye gadziriso ikasaitwa kwenguva yakareba, zvinozotungamira kune huwandu hukuru hwematambudziko. Izvo hazvisi kungotungamira kuvharika kwemidziyo, asiwo inokanganisa kuyerera kwemvura yemidziyo.
Iyo ine kukanganisa kwakakomba pakushanda kwese kweindasitiri yefiriji zvikamu, uye kunyange kupfupisa hupenyu hwese hwemaindasitiri efiriji zvikamu. Naizvozvo, kuchenesa chiyero munguva yakakosha kune maindasitiri mafiriji zvikamu.
1. Sei firiji iine chikero?
Izvo zvikamu zvikuru zvekuyera mumvura inotonhorera munyu we calcium uye magnesium munyu, uye kunyungudika kwavo kunoderera nekuwedzera kwekushisa; apo mvura inotonhorera inobata pamusoro pechitsinhanisi chekupisa, kuwedzera madhipoziti pamusoro pechitsinhanisi chekupisa.
Pane zviitiko zvina zvekusvibisa firiji:
(1) Crystallization yemunyu mune supersaturated mhinduro ine akawanda maficha.
(2) Kuiswa kwe organic colloids uye mineral colloids.
(3) Kubatana kwezvikamu zvakasimba zvezvimwe zvinhu zvine madhigirii akasiyana ekupararira.
(4) Electrochemical corrosion yezvimwe zvinhu uye microbial production, etc. Kunaya kwemusanganiswa uyu ndicho chinhu chikuru chekuwedzera, uye mamiriro ekugadzira mvura yakasimba yechikamu ndeiyi: kunyungudika kweimwe munyu kunoderera nekuwedzera kwekushisa. Zvakadai seCa (HCO3) 2, CaCO3, Ca (OH) 2, CaSO4, MgCO3, Mg (OH) 2, etc. Chechipiri, sezvo mvura inoputika, kuwanda kwemunyu wakanyungudutswa mumvura kunowedzera, kusvika pamwero we supersaturation. . Kemikari inoitika mumvura inopisa, kana mamwe maion anoita mamwe ayoni asinganyunguke emunyu.
Kune mamwe mamunyu anosangana nemamiriro ari pamusoro, mabuds ekutanga anotanga kuiswa pamusoro pesimbi, uye zvishoma nezvishoma ave zvidimbu. Iine amorphous kana latent crystal chimiro uye inounganidza kugadzira makristasi kana masumbu. Bicarbonate munyu ndiyo inonyanya kukonzera kuwedzera mumvura inotonhorera. Izvi zvinodaro nekuti heavy calcium carbonate inorasa mwero panguva yekudziya uye inoora kuita calcium carbonate, carbon dioxide nemvura. Calcium carbonate, kune rumwe rutivi, haina kunyungudika nekudaro inoisa panzvimbo yekutonhodza michina. Izvozvi:
Ca(HCO3)2=CaCO3↓+H2O+CO2↑.
Kuumbwa kwechiyero pamusoro pepamusoro pechitsinhanho chekupisa kuchasvibisa midziyo uye kupfupisa hupenyu hwebasa remidziyo; chechipiri, ichadzivisa kupisa kwekushisa kwekushisa uye kuderedza kushanda.
2. Kubviswa kwechiyero mufiriji
1. Kurongwa kwemaitiro ekudzikisa
Nzira dzekubvisa chiyero pamusoro pezvitsinhana zvekupisa dzinosanganisira kudzika kwemaoko, mechanical descaling, chemical descaling uye physical descaling.
Munzira dzakasiyana-siyana dzekudzikisa. Kudzika kwemuviri uye nzira dzekurwisa-kuyera dzakanakira, asi nekuda kweiyo misimboti yekushanda yezvakajairwa zvemagetsi kudzika zviridzwa, kune zvakare mamiriro apo mhedzisiro yacho haina kunaka, senge:
(1). Kuoma kwemvura kunosiyana munzvimbo nenzvimbo.
(2). Kuoma kwemvura kwechikwata kunoshanduka panguva yekushanda, uye chiedza chinonaya chemagetsi chekugadzirisa chiridzwa chinogona kuumba chirongwa chakakodzera chekudzikisa maererano nemasampuli emvura akatumirwa nemuiti, kuitira kuti kuderedzwa hakuchazonetseke pamusoro pezvimwe zvinofurira;
(3). Kana mushandisi akaregeredza basa rekuvhuvhuta, iyo nzvimbo yekupisa inopisa icharamba ichiyerwa.
Iyo kemikari yekudzikisa nzira inogona kungotariswa kana kupisa kwekuita kweiyo unit kwakashata uye kuyera kwakakomba, asi kunokanganisa michina, saka zvinodikanwa kudzivirira kukuvadzwa kwegirodhi uye kukanganisa hupenyu hwebasa remidziyo. .
2. Nzira yekubvisa tsvina
Dope rinonyanya kuumbwa nemapoka ehutachiona senge mabhakitiriya uye algae anonyungudika nekuberekana mumvura, akasanganiswa nedhaka, jecha, huruva, nezvimwewo kugadzira matope akapfava. Inokonzera kuora mumapombi, inoderedza kushanda uye inowedzera kuyerera kwekudzivirira, kuderedza kuyerera kwemvura. Pane nzira dzakawanda dzokugadzirisa nadzo. Iwe unogona kuwedzera coagulant kuita iyo yakamiswa nyaya mumvura inotenderera inotenderera mumaruva alum akasununguka uye igadzikane pazasi pe sump, iyo inogona kubviswa nekubuda kwetsvina; iwe unogona kuwedzera disperant kuita kuti zvidimbu zvakasimirirwa zvipararire mumvura pasina kunyura; Kuumbwa kwedhaka kunogona kudzvinyirirwa nekuwedzera kusefa kwedivi kana nekuwedzera mamwe madhiragi kuvharisa kana kuuraya tupukanana.
3. Corrosion descaling nzira
Corrosion inonyanya kukonzerwa nesludge uye corrosion zvigadzirwa zvinonamira pamusoro pehuipi yekutamisa chubhu kuti igadzire bhatiri reokisijeni uye kuparara kunoitika. Nekuda kwekufambira mberi kwekuora, kukuvadzwa kwechubhu yekupisa kunokonzeresa kutadza kwakanyanya kweiyo unit, uye kutonhora kwesimba kunodonha. Iyo unit inogona kuraswa, zvichiita kuti vashandisi vatakure kurasikirwa kukuru kwehupfumi. Kutaura zvazviri, mukushanda kwechikwata, chero bedzi hutano hwemvura huchinyatsogadziriswa, kutonga kwehutano hwemvura kunosimbiswa, uye kuumbwa kwetsvina kunodziviswa, kukanganisa kwekuora pamvura yehutano hwechikwata inogona kunyatsodzorwa. .
Kana chiyero chikawedzera chinoita kuti zvisakwanise kushandisa nzira dzakajairwa kubata nazvo, michina yekudzikisa yemuviri inogona kuisirwa anti-scaling uye dhizaini mashandiro, akadai semagetsi ekudzikisa midziyo, magineti vibration ultrasonic descaling michina, nezvimwe.
Mushure mekuyera, guruva uye algae zvakabatanidzwa, kupisa kwekushisa kwekushanda kwehutu hwekushisa kunodonha zvakanyanya, izvo zvinoderedza kushanda kwese kwechikwata.
Kuti udzivise kuwedzera uye kutonhora kwemvura yefiriji mu evaporator panguva yekushanda, kune marudzi maviri emagetsi emvura yefiriji: mhepo yakazaruka uye yakavharwa. Isu tinowanzo shandisa yakavharwa kutenderera. Nekuti idunhu rakavharwa, evaporation uye concentration hazvizoitika. Panguva imwecheteyo, mamiriro ekunze Mucherechedzo, guruva, nezvimwewo mumvura hazvizosanganiswa mumvura, uye kuwedzera kwemvura yefiriji kunenge kuduku, kunyanya kufunga nezvekupisa kwemvura yefriji. Mvura iri muevaporator inoomesa nekuti kupisa kunotorwa nefiriji painobuda muevaporator yakakura kudarika kupisa kunokwanisa kupa mvura yemufiriji inoyerera nemuevaporator, zvekuti tembiricha yemvura yemufiriji inodonha pasi pechando uye mvura inooma. Vashandi vanofanirwa kutarisisa kune zvinotevera pfungwa panguva yekushanda:
1. Kunyangwe chiyero chekuyerera chinopinda muevaporator chinopindirana nechiyero chekuyerera kweinjini huru, kunyanya kana mafiriji akawanda akashandiswa zvakafanana, kana huwandu hwemvura hunopinda muchikamu chimwe nechimwe husina kuenzana, kana kuti huwandu hwemvura hwechikwata uye pombi iri kushanda imwe-ne-imwe. A machine group shunt phenomenon. Parizvino, vagadziri vebromine chillers vanonyanya kushandisa maswiti ekuyerera kwemvura kuti vaone kana kune mvura inopinda. Kusarudzwa kwekuyerera kwemvura kunofanirwa kuenderana neyero yakayerwa yekuyerera. Conditional mauniti anogona kuve akashongedzerwa ane dynamic flow balance mavharuvhu.
2. Mushandi webromine chiller ane firiji mvura yakaderera tembiricha kudzivirira mudziyo. Kana kutonhora kwemvura yefiriji kwakaderera kupfuura +4 ° C, muenzi wacho achamira kushanda. Kana mushandisi achimhanya kekutanga muzhizha gore rega rega, anofanirwa kutarisa kana tembiricha yakadzika yekudzivirira yemvura yefiriji inoshanda uye kana iyo tembiricha yekumisikidza kukosha kwakarurama.
3. Munguva yekushanda kwebromine chiller air-conditioning system, kana pombi yemvura yakangoerekana yamira kushanda, injini huru inofanira kumira pakarepo. Kana tembiricha yemvura mu evaporator ichiri kudonha nekukurumidza, matanho anofanirwa kutorwa, sekuvhara refrigerant water outlet valve ye evaporator, kuvhura vharafu yekudhonza evaporator zvakanaka, kuitira kuti mvura iri muevaporator ikwanise kuyerera uye kudzivirira mvura. kubva kuchando.
4. Apo bromine chiller unit inomira kushanda, inofanira kuitwa maererano nemaitiro ekushanda. Kutanga kumisa injini huru, kumirira kwemaminetsi anopfuura gumi, uye wozomisa pombi yemvura yefiriji.
5. Mvura inoyerera inoshandura mufiriji yefriji uye kuchengetedzwa kwepasi-kupisa kwemvura yefriji haigoni kubviswa pakuda.
