1. Kev Tiv Thaiv me me: Siab -Kev Ruaj Ntseg Dej Backflushing (Tuaj yeem daws tau hauv tsawg li 10 feeb)
Haum rau me me blockage hauv ib lub raj hydrocyclone thiab me ntsis siab txawv txav:
Ua ntej, kaw lub feed valve kom depressurize thiab ntws cov hmoov txhuv nplej siab slurry los ntawm hydrocyclone;
Qhia siab - cov dej huv huv (siab tswj ntawm 0.8-1.0 MPa) rau hauv hydrocyclone lub qhov hluav taws xob underflow thiab rov qab rau 5-10 feeb;
Tom qab dej ntws tawm, qhib lub valve pub thiab kuaj ntau lawm. Kev tsim khoom tiav ib zaug siab thiab cov zis rov qab mus rau qhov qub.
2. Kev Tiv Thaiv Nruab Nrab: Disassemble thiab Clean Ib Theem (Ua tiav hauv 30 feeb mus rau 2 teev)
Haum rau kev txhaws hauv ntau lub raj hydrocyclone uas tsis tuaj yeem daws tau los ntawm kev rov qab los:
Kaw lub inlet thiab lub qhov hluav taws xob li qub kom depressurize thiab ntws cov kua ntau. Tshem cov kaus mom kawg ntawm qhov thaiv hydrocyclone theem;
Tshem tawm txhua lub raj hydrocyclone ib los ntawm ib qho thiab yaug lawv tus kheej nrog lub siab - rab phom dej siab. Rau cov hlab ntsha loj heev, muab tso rau hauv dej sov rau 15 feeb ua ntej yaug;
Tom qab ntxuav, rov ua dua cov raj hydrocyclone, kaw lub hau kawg, thiab ntsuas lub siab. Kev tsim khoom tuaj yeem rov pib dua thaum lub siab tau lees paub tias yog qhov qub.
3. Cuam tshuam loj thiab txhaws: tshuaj ntxuav tu (4-6 teev)
Haum rau cov xwm txheej uas cov hmoov txhuv nplej siab tau ntev tau gelatinized thiab clumped, thiab tsis tuaj yeem tshem tawm los ntawm siab - dej siab:
Tom qab disassembling cov hydrocyclone, raus tag nrho cov clogged hydrocyclone raj nyob rau hauv ib tug 0.5% zaub mov-qib sodium hydroxide tov, tshav kub rau 40-50 degree, thiab tsau rau 2-3 teev kom soften lub clumping;
Tom qab soaking, yaug kom huv si nrog siab - dej siab, ces yaug nrog dej huv kom tshem tawm cov seem alkali;
Reassemble thiab kev sim siab kom rov qab siv tau.
