Abstract
The invention provides a vacuum extraction organic recycling technique, wherein, a vacuum pump sucks organic liquid into a recycling tube; after settlement and phase-dividing are carried out to the organic liquid, water content is discharged from the lower part of the recycling tube; the organic liquid is transferred to a stirring tube by a centrifugal pump for purifying and the purified organic liquid is returned for extraction. The technique can effectively settle and purify the organic liquid and prevent grease from forming three phases when being recycled.
Description
Technical field
The present invention relates to negative-pressure type extraction organic recovery technique.
Background technology
Organic carrying secretly is the problem that often occurs in the extraction production process, and organic recovery scarce capacity causes organic time weak effect, the cycle is long, the rate of recovery is low.Organic recovery originally is by raising surplus liquid pool liquid level, the organic of surplus liquid-pool surface overflowed in the recovery pond, raise with centrifugal pump again and deliver to that mixing drum purifies, after the clarifying treatment, again with organic send back in the extracting system recycling.
This method is difficult to control, tends to bring into a large amount of moisture content during recovery, again the profit mixing and emulsifying is formed three-phase under the centrifugal pump effect.
Summary of the invention:
Purpose of the present invention just provides a kind of negative-pressure type extraction organic recovery technique.
This technology is as follows:
By vavuum pump organic liquor is sucked recovery cylinder, after the clarification phase-splitting, moisture content is discharged by the recovery cylinder bottom, and with organic mixing drum purified treatment of delivering to, organic after the purification returns extraction with centrifugal pump.
The present invention is the defecate and purify organic liquor effectively, and oil-water emulsion forms three-phase when preventing to reclaim.
Claims (1)
1. a negative-pressure type extraction organic recovery technique is characterized in that by vavuum pump organic liquor being sucked recovery cylinder, and after the clarification phase-splitting, moisture content is discharged by the recovery cylinder bottom, and with organic mixing drum purified treatment of delivering to, organic after the purification returns extraction with centrifugal pump.
