Spiral heat exchangers, ine compact dhizaini uye yakanyanya kupisa kupisa kushanda zvakanaka, inoshandiswa zvakanyanya muchikamu chemakemikari, chemishonga, uye simba. Kuti vawedzere zvizere mabhenefiti avo ekuita, kugona anotevera akakosha mashandisiro maitiro kwakakosha:
1. Kugadziridza Fluid Distribution
Kusaenzana kwemvura kugovera mukati meiyo spiral chiteshi kunogona kutungamira kune yenzvimbo kuyera kana kuwedzera kupisa kwekudzivirira. Zvinokurudzirwa kuisa ndiro yekutungamira pane inopinza kuti ive nechokwadi chekuyerera kwezvose zviri zviviri midhiya muchiteshi chemhepo. Pakukwirisa-viscosity fluid, kuyerera kweinopinza kunogona kuwedzerwa zvakakodzera (inokurudzirwa 0.5-1.2 m/s) kudzivirira nzvimbo dzakafa. Mienzaniso inoshanda inoratidza kuti kugovera kwemvura kwakaringana kunogona kuvandudza kugona kwekutamisa kupisa ne15% -20%.
2. Temperature Differential Control uye Scale Prevention
Mudziyo uyu wakakodzera kushanda nekusiyana kwekushisa kweZviri pasi kana kuenzana ne50 degree. Kunyanya kupisa kusiyanisa kunogona kukonzera nyore kushushikana kwekupisa uye deformation. Pakubata scaling-prone media, zvinokurudzirwa kuchengetedza kuyerera kweKukura kupfuura kana kuenzana ne0.8 m/s (kune masisitimu emvura) kana Kupfuura kana kuenzana ne0.3 m/s (kumaoiri masisitimu) kudzivirira kuisa sikeri kuburikidza nemuchina wekutsvaira. Nguva dzose 5% citric acid cycle yekuchenesa (pa 60-70 dhigirii kwemaawa maviri) inogona kudzoreredza kupisa kwekushisa kusvika pamusoro pe85%.
3. Pressure Balance Maintenance
Iyo spiral plate's pressure capacity inowanzoita 0.6-1.0 MPa. Kudzvinyirirwa kusiyanisa mhiri kweplate kunofanira kunyatsotariswa panguva yekushanda. Kana ikadarika kukosha kwekugadzira kwe0.3 MPa, bypass pressure relief inofanira kukurumidza kuitwa. Munguva yenguva yakawedzerwa yekusaita basa, zvinokurudzirwa kuchenesa zvakasara media nemhepo yakamanikidzwa uye kuchengetedza zvishoma yakanaka kudzvanywa (0.02-0.05 MPa) kudzivirira oxidation corrosion.
4. Kuchinja kune Special Operating Conditions
Kana uchibata corrosive media, 316L Stainless steel kana titanium spiral plates anodiwa, uye welds anofanirwa kuongororwa PT. Kune zvinopisa uye zvinoputika zvinwiwa, nitrogen yekudzivirira system uye electrostatic grounding inofanirwa kuiswa kuti ive nechokwadi chekushanda kwakachengeteka.
Kuziva nzira idzi kunogona kuwedzera hupenyu hwe spiral heat exchanger ne 3-makore mashanu uye kuderedza kushandiswa kwesimba ne10-15%. Kugara uchirekodha maitiro ekushanda (senge inlet uye yekubuda tembiricha musiyano, kudzvanywa kudonha shanduko) uye kumisikidza mafaera ekugadzirisa inzira dzakakosha dzekuvimbisa kushanda kwenguva refu uye kwakanaka.
