DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0022] An objective of the present disclosure is to provide a composite vortex reactor to solve the problems in the prior art, such that a flow field environment in the reactor is more diversified, the flow field shear is easy to control, the mixing effect among the materials is improved, and the interface mass transfer efficiency is increased.

[0023] In order to make objectives, features, and advantages of the present disclosure more apparently and understandably, the following further describes the present disclosure in detail with reference to accompanying drawings and specific embodiments.

Embodiment I

[0024] As shown in FIG. 1 to FIG. 2, this embodiment provides a composite vortex reactor 100. The composite vortex reactor 100 comprises a Rankine cyclone reactor 1 and a Taylor vortex reactor 2. The Rankine cyclone reactor 1 comprises a reaction chamber 11, a side wall of the reaction chamber 11 is provided with a first inlet pipe 12 and a second inlet pipe 13. Fluids entering the reaction chamber 11 through the first inlet pipe 12 and the second inlet pipe 13 may form a gyro-fluid in the reaction chamber 11. The middle of the top of the reaction chamber 11 is provided with a gyroscopic outlet pipe 14. The Taylor reactor 2 comprises an inner cylinder 21 and an outer cylinder 22 which are coaxially provided. The inner cylinder 21 is driven by a rotary driving device 23 to rotate. An annular reaction space 24 is formed between the inner cylinder 21 and the outer cylinder 22. The middle of the bottom of the annular reaction space 24 communicates with the reaction chamber 11 through the gyroscopic outlet pipe 14, and the cross sectional area of the annular reaction space 24 gradually increases from bottom to top. The upper end of the outer cylinder 22 is provided with a reaction outlet pipe 25 communicating with an upper portion of the annular reaction space 24.

[0025] During use of the composite vortex reactor, two types of reaction fluids (particle materials) respectively enter the reaction chamber 11 through the first inlet pipe 12 and the second inlet pipe 13 to form the gyro-fluid in the reaction chamber 11. The gyro-fluid enters the annular reaction space 24 in the Taylor vortex reactor 2 through the gyroscopic outlet pipe 14, and the inner cylinder 21 is driven by the rotary driving device 23 to rotate in order to make the gyro-fluid generate variable-size Taylor vortex while performing gyroscopic movement in the annular reaction space 24, such that the flow field environment in the reactor is more diversified. Moreover, as the cross-sectional area of the annular reaction space 24 gradually increases from the bottom to the top, local turbulent shear and contact reaction time of the reaction materials in the annular reaction space 24 may be regulated and controlled, thus remarkably improving the mixing effect among the materials and increasing the interface mass transfer efficiency. The materials after reaction flow out from the reaction outlet pipe 25.

[0026] In this embodiment, the first inlet pipe 12 and the second inlet pipe 13 are respectively arranged at both sides of the reaction chamber 11 and parallel to each other. The first inlet pipe 12 and the second inlet pipe 13 have opposite fluid entering directions. The fluids enter the reaction chamber 11 from the first inlet pipe 12 and the second inlet pipe 13 in a tangential direction of the outer edge of the reaction chamber 11, thus facilitating the formation of gyro-fluid.

[0027] In this embodiment, the reaction outlet pipe 25 and the first inlet pipe 12 are located at the same side and parallel to each other. The reaction outlet pipe 25 has a fluid outflow direction the same as the fluid entering direction of the first inlet pipe 12, the gyro-fluid flows out along a tangential direction of the outer cylinder 22, making the outflow process smoother.

[0028] In this embodiment, the reaction chamber 11 is a revolution body-shaped reaction chamber, preferably a disc type reaction chamber. In other embodiments, the reaction chamber 11 may also be an elliptic reaction chamber. However, the shape of the reaction chamber 11 is not limited to above two types, other reaction chamber shapes capable of forming the gyro-fluid are within the scope of protection of the present disclosure.

[0029] In this embodiment, the outer cylinder 22 is an equal-inner-diameter outer cylinder, the inner diameter of which is equal everywhere from the lower end to the upper end. The inner cylinder 21 is a variable-outer-diameter inner cylinder, the outer diameter of which gradually decreases from the lower end to the upper end. The outer cylinder and the inner cylinder are both simple in structure and convenient to manufacture, facilitating to obtain the annular reaction space 24 with gradually changed cross sectional area. The change of the outer diameter of the variable-outer-diameter inner cylinder along the height is specified by a special function curve based on the conservation of momentum in fluid flow.

[0030] In this embodiment, the rotary driving device 23 is a driving motor which is convenient to control. The rotational speed of the inner cylinder 21 may be controlled by the driving motor, thus regulating the flow field environment of the annular reaction space 24, especially the local turbulent shear rate.

[0031] In this embodiment, the first inlet pipe 12 and the second inlet pipe 13 are respectively connected to a driving pump (not shown in the figure), such that the flow rates of the two types of fluids entering the reaction chamber 11 may be controlled by the driving pumps respectively.

Embodiment II

[0032] As shown in FIG. 3, this embodiment provides a composite vortex reactor 100. The difference from the Embodiment I is that in this embodiment, the outer cylinder 22 is a variable-inner-diameter outer cylinder, the inner diameter of which gradually increases from the lower end to the upper end; and the inner cylinder 21 is a variable-outer-diameter inner cylinder, the outer diameter of which gradually increases from the lower end to the upper end. The spacing distance between an outer ring (defined by the inner diameter of the outer cylinder) and an inner ring (defined by the outer diameter of the inner cylinder) of the cross section of the annular reaction space 24 is equal from the bottom to the top. The variation of the inner diameter of the variable-inner-diameter outer cylinder and the outer diameter of the variable-outer-diameter inner cylinder along the height is specified by a special function curve according to the conservation of momentum in fluid flow.

[0033] Several examples are used for illustration of the principles and implementation methods of the present disclosure. The description of the embodiments is merely used to help illustrate the method and its core principles of the present disclosure. In addition, a person of ordinary skill in the art can make various modifications in terms of specific embodiments and scope of application in accordance with the teachings of the present disclosure. In conclusion, the content of this specification shall not be construed as a limitation to the present disclosure.
