Problems solved by technology

[0002] As we all know, the separation methods of existing oil-water separation equipment can be roughly divided into gravity separation, centrifugal separation, electric separation, adsorption separation, air flotation separation, etc. These oil-water separation methods all have their own substantial defects, and the oil-water separation takes a long time. , low oil extraction efficiency, and low oil purity. If the gravity separation method adopts the form of a sedimentation tank, there will be a dead zone in the liquid flow. A large amount of odor is produced; the maintenance of power components of centrifugal separation equipment is difficult, and it is currently only used in laboratory analysis equipment, etc.
[0003] In addition, due to the incomplete separation of the oil and water separated by the above separation method, the oil quality is poor, and storage and reuse are difficult.

Embodiment

[0030] Embodiment: When the present invention is working, the PLC controller is powered on, and the refrigeration and heating system refrigerates the condensing plate and heats the degreasing condenser and the water-cooled condenser. When the condensing plate reaches a specified temperature, the specified temperature is higher. The freezing point of water is equal to or lower than the freezing point of oil. The condensation plate descends and contacts the liquid surface. The oil on the surface of the liquid is cooled under the action of the condensation plate to become grease and adheres to the bottom of the condensation plate. Then lift the condensation plate and use it. The oil scraper scrapes the grease under the condensation plate into the degreasing tank, and the grease is heated by the oil-cooled condenser under the degreasing tank to become oil, and flows into the oil receiving barrel through the oil outlet at the bottom of the degreasing tank.

Abstract

The invention discloses a condensation type oil-water separation method. The method is characterized in that high-efficiency oil-water separation is realized in a temperature range where oil reaches the freezing point but water does not reach the freezing point on the basis of the difference of the freezing points of oil and water. Therefore, the method has the advantages of novel structure, highoil extraction efficiency, high outlet oil purity and the like.

Description

technical field [0001] The invention relates to the technical field of oil-water separation, in particular to a condensation-type oil-water separation method. Background technique [0002] As we all know, the separation methods of existing oil-water separation equipment can be roughly divided into gravity separation, centrifugal separation, electric separation, adsorption separation, air flotation separation, etc. These oil-water separation methods all have their own substantial defects, and the oil-water separation takes a long time. , low oil extraction efficiency, and low oil purity. If the gravity separation method adopts the form of a sedimentation tank, there will be a dead zone in the liquid flow. A large amount of odor is produced; the maintenance of power components of centrifugal separation equipment is difficult, and it is currently only used in laboratory analysis equipment. [0003] In addition, due to the incomplete separation of the oil and water separated by...
