87 to raise the rectification precision of rectification tower further, ensure certainly tower implement catharsis is clean, prevent the alternate pollution in use process even at the same time. How does catharsis rectify tower just calculate clean? Should have meticulous operation according to such flow.
According to the need of actual condition, what end in the job of rectification tower is backward the dissolvent with its inspiratory and right amount interior, undertake warming up to often press circumfluence, take adsorption entirely as far as possible in the stock inside the tower. Next direct by rectification tower inward ministry adds right amount clear water or pass cat head vacuum to will rinse into makings valve in inspiratory boiler, undertake preliminary catharsis with clear water, want dropt to be decided according to actual condition even as to catharsis water otherwise.
After finishing with vacuum condition to engulf of rectification tower interior 1% right-and-left lye, warm up next 110 ¡æ of 100 ¡« , complete circumfluence collects fraction after a hour, basically be to use buck catharsis conduit and device. Undertaking hot water flows too even next, right amount clear water is added in rectification tower, warm up the purpose that the buck in achieving scour off equipment and conduit collects completely again after circumfluence.
After all till, of rectification tower be basically clean, but its clean flow to still do not have an end, still need catharsis of farther vacuum drying, methanol and solvent catharsis. Use vacuumize drying means dry rectify tower, the vacuum after affirming evaporate does not have seeper its interior engulf reclaims eligibly class methanol dissolvent, warm up likewise undertake complete circumfluence, right amount collect come to collect coal tub individually.
Ask according to the production of different breed next, vacuum again to the dissolvent with the right amount engulf in rectification tower, warm up undertake complete circumfluence, right amount collect come to collect coal tub individually. Vacuumize drying means still is used to undertake after solvent catharsis dry, after the staff member affirms qualification to equipment supervision, ability is regarded as the catharsis of rectification tower handle an end.
