Description
[technical field]
The present invention relates to chemical industry abstraction technique field, specifically, is a kind of modified rotating disc column inner member be applicable to containing solid phase extraction operation.
[background technology]
Extraction is one of unit operations important in chemical separation engineering.Generally speaking, extracting system is liquid-liquid two-phase, but industrial to be also no lack of with liquid-solid and liquid-liquid-solid system be representative containing solid extraction system.Solid particle in extraction system easily forms deposition or causes equipment to block in extraction equipment, affects the normal operating of extraction equipment, and thus exploitation is applicable to containing the equipment of solid phase extraction operation is the problem that industrial production needs to solve.
Rotating disc column is one of industrial modal equipment for extraction, has the series of advantages such as structure is simple, production capacity large, convenient operating maintenance, energy consumption are low.Another important feature of rotating disc column is that it can process the extraction system containing solid particle, but be only applicable to low-solid content operation, when system solid content is too high, solid phase easily deposits at column plate, and build up due to the adhesive attraction between particle, affect extracting operation, even cause tower body to block.
The present invention, by the analysis of rotating disc column flow field structure, has carried out Curve guide impeller to rotating disc column inner member, to improve it to the disposal ability containing solid phase extraction system.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, a kind of modified rotating disc column inner member be applicable to containing solid phase extraction operation is provided; Appropriate design is carried out to rotating disc column inner member, optimizes the distribution of rotating disc column interior flow field, eliminate the flow dead of rotating disc column inside, reduce the deposition of solid product on rotating disk and fixed ring, to improve extraction tower to the disposal ability containing solid phase extraction system.
The object of the invention is to be achieved through the following technical solutions:
Be applicable to the modified rotating disc column inner member containing solid phase extraction operation, it comprises rotating disk and fixed ring, it is characterized in that, rotating disk and fixed ring adopt cambered design.
Technically say, the eddy current that fixed ring is formed with the radian on rotating disk and Ta Nei material heterogeneous fluid suits mutually, prevents the generation of flow dead;
The upper side of fixed ring is processed as the streamline arc in applicable heterogeneous flow field, or the upper and lower side of fixed ring is processed as the streamline arc in applicable heterogeneous flow field simultaneously.
The upper side of rotating disk is processed as the streamline arc in applicable heterogeneous flow field, or the upper and lower side of rotating disk is processed as the streamline arc in applicable heterogeneous flow field simultaneously.
Arc diameter is 0.1-1.0 times of rotating disc column tower joint height.
Fixed ring, rotating disk arcuate flanks material selection criteria are: if solid particle is in aqueous phase, then select oleophylic or hydrophobic material; If solid particle is in oil phase, then select hydrophilic or oleophobic material;
The arc of fixed ring, disc surfaces will meet the hydrodynamic characteristic of tower inner fluid, is beneficial to the development of eddy current in tower;
Compared with prior art, good effect of the present invention is:
The present invention improves the fixed ring of traditional rotating disc column and rotating disk, adopt the project organization of arc-shaped interface, the geometry interface of multiphase flow field structure and tower in rotating disc column is had suit preferably, eliminate flow dead in tower, thus the turbulence characteristic made full use of in tower prevents solid precipitation, improve rotating disc column to the disposal ability containing solid phase extraction system.

[detailed description of the invention]
The present invention is below provided a kind of detailed description of the invention being applicable to the modified rotating disc column inner member operated containing solid phase extraction.
Embodiment 1
Be applicable to the modified rotating disc column inner member containing solid phase extraction operation, it comprises rotating disk and fixed ring, it is characterized in that, rotating disk and fixed ring adopt cambered design.
Technically say, the eddy current that fixed ring is formed with the radian on rotating disk and Ta Nei material heterogeneous fluid suits mutually, prevents the generation of flow dead;
The upper side of fixed ring is processed as the streamline arc in applicable heterogeneous flow field, or the upper and lower side of fixed ring is processed as the streamline arc in applicable heterogeneous flow field simultaneously.
The upper side of rotating disk is processed as the streamline arc in applicable heterogeneous flow field, or the upper and lower side of rotating disk is processed as the streamline arc in applicable heterogeneous flow field simultaneously.
Arc diameter is 0.1-1.0 times of rotating disc column tower joint height.
Fixed ring, rotating disk arcuate flanks material selection criteria are: if solid particle is in aqueous phase, then select oleophylic or hydrophobic material; If solid particle is in oil phase, then select hydrophilic or oleophobic material;
The arc of fixed ring, disc surfaces will meet the hydrodynamic characteristic of tower inner fluid, is beneficial to the development of eddy current in tower.
Refer to accompanying drawing 1, the structure with Novel arc inner member rotating disc column mainly comprises tower body, arc rotating disk, arc fixed ring, rotating shaft, motor.Analyze known by drop behavior in tower and fluid Simulation, larger difference is there is between fluid vortex structure in traditional extraction tower and the geometry of tower, thus above fixed ring, rotating disk, certain flow dead is defined, as shown in Figure 2, wherein 2a is speed cloud atlas and the polar plot of continuous phase, can find obvious vortex feature, and 2b is the flow dead distribution map by velocity magnitude definition, wherein black region represents flow dead, and white portion represents the vortex of turbulence.Flow dead is the principal element causing solid precipitation, thus must eliminate flow dead to improve tower to the disposal ability containing solid phase extraction system.
Accompanying drawing 3 is the flow field schematic diagram of rotating disc column after employing modified inner member, and 3a is continuous phase speed cloud atlas and polar plot, and 3b is flow dead distribution map.As seen from the figure, in rotating disc column, the cambered design of fixed ring, rotating disk has suited the vortex structure in heterogeneous flow field in tower well, effectively eliminate the flow dead above column plate, and the turbulence characteristic making full use of eddy current prevents solids particles precipitate, thus improve whole tower to the disposal ability containing solid phase extraction system.Show the further analysis improving rear rotating disc column inner fluid mechanics, in raising containing while solid system disposal ability, new inner member design does not cause the reduction of extraction tower operating characteristics.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, without departing from the inventive concept of the premise; can also make some improvements and modifications, these improvements and modifications also should be considered within the scope of protection of the present invention.
