Main trait: Simple structure, installed speed, less investment, flexible
production Process flow: Pretreatment material are transported by screw conveyor into
extraction workshop, through bucket elevator and air screw conveyor
into batch extractor to extracte with dilute miscella and fresh
solvent. The extraction meal through steam blowing and steam stripping in
the batch extraction to desolventized. Then transport into meal
storehouse. The miscella into misella tank, then into the first rasing film
evaporator to evaporate solvent, next into the second rasing
filming evaporation to evaporate solvent again, at last into
stripping column to evaporate residual solvent. The extraction
crude oil into crude oil tank then into refining workshop. The solven vapour from rasing film evaporators and stripping column
into condensers to condense, condensation water into water
separator to separate, then the separation solvent back to solvent
tank, the waster-water into waster-water boiling tank to cook, then
to water seal tank. The solvent carrying-air from the top of all the equipment into
last condenser to condense, the vent gas into absorbing column to
recover solvent again. Main model: 5t/d,8t/d,10t/d,15t/d,20t/d. Main equipment: Batch extractor, Condenser, Film evaporator, Stripping column,
Absorbing column etc. |
