Oil-water separation device with flow guide plate

Abstract

The invention discloses an oil-water separation device with a flow guide plate, which comprises a conical oil-water separator, wherein the flow guide plate is arranged at the outlet end of an ingresspipe of the oil-water separator, the flow guide plate is segment-shaped and is fixedly connected with the ingress pipe through a rod-shaped body, an adjusting pipe is arranged at the lower part of theingress pipe, the adjusting pipe is screwed or clamped with the ingress pipe, an oil outlet is formed in upper part of oil-water separator, and a condensation pipe and a return pipe are arranged at the bottom of the oil-water separator. The flow direction of the mixed liquid can be impacted vertically and downwards by the flow guide plate, the mixed liquid is guided to be uniformly distributed onthe whole section along the radial direction of the flow guide plate and slowly moves downwards, direct impact on the oil-water mixed liquid in the separator is eliminated, and part of the oil-watermixed liquid is prevented from returning to a distillation device or entering fresh flower dew without being separated. The device can continuously and efficiently separate and collect volatile oil, has the characteristics of high separation efficiency and good continuity for oil-water mixed liquid with low volatile oil content, is easy to disassemble and replace, is low in manufacturing cost, canbe universally compatible with water vapor distillation equipment used in current production, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to an oil-water separation device for extracting volatile oil by steam distillation. Background technique [0002] Steam distillation is the most commonly used continuous dynamic extraction method of volatile oil. It has the advantages of simple structure, easy operation, high efficiency, no pollution, and no solvent residue in the obtained volatile oil. It is widely used in actual production. [0003] The oil-water separator is the core component in the process of preparing volatile oil by steam distillation, and the oil-water separation effect is one of the main factors affecting the oil yield. Gravity sedimentation oil-water separation method is a traditional and economical oil-water separation method, which utilizes the immiscibility and density difference between oil and water to achieve the separation of volatile oil and The separation of water has the advantages of simple structure, small flow resistance and the ability to...

Problems solved by technology

However, in the actual application process, it was found that because the oil-water mixture still had a high initial velocity when it flowed out of the inlet pipe, it caused the disturbance of the oil-water mixture in the separation chamber; at the same time, a large number of oil droplets rushed into the bott...
