Technical field

The utility model relates to lipin deacidifying processing technique fields, more particularly, to a kind of depickling vacuum holding of oil and fat refining It sets.

Background technique

In not refined various crude oils, contain a certain number of free fatty acids, removes free fatty acid in grease Process be referred to as depickling.The method of depickling has the methods of alkali refining, distillation, solvent extraction and esterification.It is wherein most widely used For alkali refining method and the way of distillation.Distillation depickling method is also known as physical refining method, i.e. free fatty acid in crude oil is carried out with bases Neutralization reaction, but vacuum steam distillation is borrowed to reach a kind of method of refining of depickling purpose.Distillation depickling method generallys use steam Ejector vacuum pump realization vacuumize, this kind of mode need to consume a large amount of vapor, therefore water consumption is high, and will form largely discard Condensed water, causes that production site is wet and slippery and working environment is damp and hot, and there are potential security risks.

Utility model content

The purpose of this utility model is intended to overcome the shortcomings of the prior art, and it is good and safe to provide a kind of water-saving result The depickling vacuum plant of the good oil and fat refining of property.

In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:

A kind of depickling vacuum plant of oil and fat refining, including at least a set of physical refining deacidification tower；It further includes condenser, Fatty acid trap and roots pump systems with water ring；The upper end of the physical refining deacidification tower passes through first pipe and condenser The outlet of entrance connection, the condenser is connect by second pipe with the entrance of fatty acid trap；The fatty acid trapping The upper end of device is connect by third pipeline with roots pump systems with water ring；The lower end setting of the fatty acid trap has valve Drainage conduit.

Preferably, the condenser uses open shell and tube conde er.

Preferably, the condenser uses tube-in-tube condenser.

Preferably, the roots pump systems with water ring uses second level roots pump systems with water ring.

Preferably, the valve uses solenoid valve.

Preferably, the physical refining deacidification tower is two sets.

Compared with prior art, the utility model has the advantages that

The utility model realizes the vacuumize process of extracting tower using roots pump systems with water ring, and cooperates condenser and rouge Fat acid trap realizes the depickling of grease, this kind of mode simple process does not generate condensed water, it can be ensured that work-yard is dry, really Guarantor's comfortable working environment is good, then improves safety and the comfort of operation.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it can also be obtained according to these attached drawings other attached drawings.

Fig. 1 is the schematic diagram of the utility model one embodiment.

Fig. 2 is the schematic diagram of second embodiment of the utility model.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor Every other embodiment obtained, fall within the protection scope of the utility model.In the following description, in order to clearly demonstrate originally The structure and working method of utility model will be described on the basis of attached drawing by many Directional words, but should be incited somebody to action The Word Understandings such as "front", "rear", "left", "right", "upper", "lower" are not construed as word of limitation for convenience of term.

Embodiment 1

The depickling vacuum plant of oil and fat refining shown in Fig. 1, including two sets of physical refining deacidification towers 1, condenser 2, fatty acid Trap 3 and roots pump systems with water ring 4；The condenser 2 uses open shell and tube conde er；Two sets of physical refinings are de- The upper end of acid tower 1 connect by first pipe 5 with the entrance of condenser 2, the outlet of the condenser 2 pass through second pipe 6 and The entrance of fatty acid trap 3 connects；The upper end of the fatty acid trap 3 passes through third pipeline 7 and Roots's Water-ring vacuum machine 4 connection of group；The lower end setting of the fatty acid trap 3 has the drainage conduit 9 of valve 8.

Wherein, the roots pump systems with water ring 4 preferably uses second level roots pump systems with water ring, it is clear that can also be used three Grade roots pump systems with water ring.

Wherein, the valve 8 preferably uses solenoid valve, it is clear that manually-operated gate can also be used.

Embodiment 2
