A reinforcing ring is provided on the lower surface of the bottom plate within the lower chamber, and several radially distributed reinforcing ribs are also provided on the lower surface of the bottom plate. The outer ends of the radial reinforcing ribs are connected to the inner wall of the cylindrical shell, and the inner ends of the radial reinforcing ribs are connected to the outer wall of the reinforcing ring. A reinforcing ring plate connected to the bottom side of the radial reinforcing ribs is connected to the lower end of the cylindrical shell. Advantages of this application: This application increases the strength of the bottom of the cylindrical body by using components such as reinforcing rings, radial reinforcing ribs, and reinforcing ring plates to improve the structural strength of the cylindrical body, prevent deformation, and solve the structural strength and production safety problems of large-size rotating beds. However, traditional supergravity beds still suffer from low liquid holding capacity and low efficiency in mass transfer, mixing, and separation processes. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a high liquid holding capacity and strong mass transfer hypergravity bed, which has a higher liquid holding capacity and better mixing and mass transfer effect.

[0004] To achieve the above objectives, the present invention provides a high liquid-holding capacity and strong mass transfer hypergravity bed, comprising a shell, an air inlet, an air outlet, a liquid inlet pipe, and a liquid outlet. Multiple sets of upper fixed disks and lower rotating disks are arranged in pairs inside the shell. A liquid inlet pipe is located at the center of the shell, and the liquid inlet pipe has multiple spray holes laterally opened corresponding to each set of upper fixed disks and lower rotating disks. Both the lower rotating disk and the upper fixed disk are concave cones facing downwards. The center of the lowest lower rotating disk is closed, and the lower rotating disks above the lowest layer have... Each central hole is equipped with an annular baffle plate. The inlet pipe passes through the central hole. The upper turbulence ring is vertically fixed on the upper fixed plate, and the lower turbulence ring is vertically fixed on the lower rotating plate. Drip holes are provided on the upper and lower turbulence rings. The upper fixed plate and the lower rotating plate are each equipped with multiple sets of upper and lower turbulence rings that are relatively distributed. The upper and lower turbulence rings are distributed in multiple layers outward from the center. The upper and lower turbulence rings are staggered and locally horizontally aligned.

[0005] Preferably, the conical lower turntable and upper fixed plate are distributed relatively parallel to each other.

[0006] Preferably, the cone angles of the lower turntable and the upper fixed plate are between 120° and 175°.

[0007] Preferably, the air inlet is provided on the left side of the housing, the bottom wall of the housing is an inclined surface with the left side higher than the right side, the right side has a liquid outlet, and the upper section is funnel-shaped.

[0008] Preferably, the plurality of upper fixed plates are fixed at the middle position on the housing, the plurality of lower turntables are fixed to each other, and the drive motor drives the lower turntables via the drive shaft.

[0009] Preferably, the upper fixed plate is fixed to the housing by an inner fixing rod, and the inner fixing rod is fixed to the inner side of each upper fixed plate; the lowest layer of the lower turntable is fixed to the drive shaft, the drive shaft is equipped with a drive motor, and the edge of the lowest layer of the lower turntable is fixed to each of the upper lower turntables by an outer fixing rod. The drive motor drives the lowest layer of the lower turntable through the drive shaft, and then drives all the upper lower turntables.

[0010] The present invention has the following significant advantages over the prior art: (1) Significantly increases liquid holding capacity and residence time. The conical structure of this application forms a centrifugal potential well inside the lower rotating disk. After the liquid enters from the center, it must overcome gravity to move to the edge, which leads to a significant increase in the amount of liquid held in the packing layer, thus increasing the liquid holding capacity of the lower rotating disk. Compared with ordinary planar rotors, this structure can effectively prolong the reaction and mass transfer time of the liquid phase in the hypergravity field, which is particularly beneficial for slow chemical reactions or the absorption of sparingly soluble gases.

[0011] (2) Enhanced liquid phase dispersion and micro-mixing efficiency. In this application, as the liquid climbs towards the edge in the conical rotating disk, it will be subjected to stronger shear force and friction under the support of gravity, which will make the liquid be cut into finer pieces by the packing, forming a thinner liquid film or finer droplets, greatly increasing the contact specific surface area between the gas and liquid phases and accelerating the renewal of the phase interface, thereby significantly improving the mass transfer coefficient.

[0012] (3) The structure of the edge of the cone-shaped lower turntable being higher than the center forms a natural centrifugal barrier on its outer edge. Under high-speed rotation, the centrifugal barrier can effectively prevent flooding and mist entrainment, allowing the equipment to operate stably at higher gas velocities. This not only ensures the cleanliness of the outlet gas but also broadens the operational flexibility of the equipment, providing excellent anti-entrainment and gas-liquid separation performance.

[0013] (4) In this application, multiple sets of upper fixed plates and lower rotating plates are simultaneously set up, and liquid is sprayed outward from the center. In the traditional structure, if the liquid inlet pipe is to enter from the center, it must go deep into the center of the equipment, occupying the space in the center position, which makes it impossible for the rotating shaft to enter. The structure of this application, in which "the upper fixed plate is fixed to the housing with an inner fixing rod, and the inner fixing rod is fixed to the inner side of each upper fixed plate; the lower rotating plate at the bottom layer is fixed to the drive shaft, the drive shaft is equipped with a drive motor, and the edge of the lower rotating plate at the bottom layer is fixed to each of the upper lower rotating plates with an outer fixing rod, and the drive motor drives the lower lower rotating plate at the bottom layer through the drive shaft, thereby driving all the upper lower rotating plates", solves the technical problem of incompatibility. After realizing the synchronous operation of multiple rotating plate systems and the structure of central liquid spraying, the working efficiency can be greatly improved. Attached Figure Description

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] Reference Figure 1-5As shown in Embodiment 1 of the present invention, a high liquid holding capacity and strong mass transfer hypergravity bed includes a shell 1. The shell 1 is connected to an air inlet, an air outlet, a liquid inlet pipe 4, and a liquid outlet. Multiple sets of upper fixed disks 2 and lower rotating disks 3 are arranged in pairs inside the shell. A liquid inlet pipe 4 is located at the center of the shell 1. The liquid inlet pipe 4 has multiple spray holes 5 laterally opened corresponding to each set of upper fixed disks 2 and lower rotating disks 3. Both the lower rotating disks 3 and the upper fixed disks 2 are concave cones. The center of the lowest rotating disk 3 is closed (the closed center of the lower rotating disk 3 can receive all the sprayed liquid and continue to achieve mass transfer and multiphase flow reaction in the centrifugal force field of the lowest rotating disk). The central holes of the lower rotating disks 3 above the lowest layer are equipped with annular baffles. 11. The baffle plate 11 can prevent liquid from flowing down from the central hole when the initial centrifugal force is insufficient. The inlet pipe 4 passes through the central hole. The conical lower rotating plate 3 and upper fixed plate 2 are relatively parallel to each other. The upper turbulence ring 6 is vertically fixed on the upper fixed plate 2, and the lower turbulence ring 7 is vertically fixed on the lower rotating plate 3. The upper turbulence ring 6 and lower turbulence ring 7 are provided with drip holes. The upper fixed plate 2 and lower rotating plate 3 each have multiple sets of upper turbulence rings 6 and lower turbulence rings 7 distributed relatively. The upper turbulence rings 6 and lower turbulence rings 7 are distributed in multiple layers outward from the center. The upper turbulence rings 6 and lower turbulence rings 7 are staggered and locally horizontally aligned. The horizontally staggered structure helps ensure the mass transfer efficiency of the liquid. The cone angle of the lower rotating plate 3 and upper fixed plate 2 is between 120° and 175°. In this embodiment, a cone angle of 170° is selected. Within this angle range, the influence of gravity can be fully utilized, and the flow direction can be avoided from being adversely affected. The air inlet is located on the left side of the housing 1. The bottom wall of the housing 1 is inclined with the left side higher than the right side. The right side has a liquid outlet, and the upper part is funnel-shaped. The funnel-shaped liquid outlet is conducive to the collection and discharge of liquid.

[0021] Reference Figure 1-5 As shown, in order to simultaneously achieve the setup of multiple upper fixed plates and lower rotating plates, and the spraying of liquid outward from the center, based on the above embodiment 1, multiple upper fixed plates 2 are fixed to the middle position of the housing 1, and multiple lower rotating plates 3 are fixed to each other. The drive motor drives the lower rotating plates 3 via the drive shaft 9. The upper fixed plates 2 are fixed to the housing 1 by inner fixing rods 8, which are fixed to the inner side of each upper fixed plate 2; the lowest layer of lower rotating plates 3 is fixed to the drive shaft 9, which is equipped with a drive motor. The edge of the lowest layer of lower rotating plates 3 is fixed to each of the upper lower rotating plates 3 by an outer fixing rod 10. The drive motor drives the lowest layer of lower rotating plates 3 via the drive shaft, thereby driving all the upper lower rotating plates 3. The above technical solution of this application solves the technical problem of incompatibility. After realizing the synchronous operation of multiple rotating plate systems and the structure of central liquid spraying, it can significantly improve work efficiency.

[0022] Embodiment 2 of the present invention is basically the same as Embodiment 1, except that: based on Embodiment 1, the cone angles of the lower turntable 3 and the upper fixed plate 2, as well as the distribution density of the turbulence rings, are optimized. Specifically, the cone angles of the lower turntable 3 and the upper fixed plate 2 are preferably 150°. This angle, compared to the angle in Embodiment 1, can increase the influence of gravity. Under this structure, the liquid layer thickness increases, and the mass transfer efficiency is improved.

[0023] To accommodate the fluid characteristics introduced by the large cone angle structure, the radial distribution density of the upper and lower turbulence rings 6 and 7 is adjusted. Specifically, in the inner region near the center, the distribution density of the upper and lower turbulence rings 6 and 7 is increased by 30%-50% compared to Example 1. Since the liquid flows at a relatively high velocity in the initial stage of rotation, the high-density turbulence rings generate stronger shear force, preventing the liquid from directly short-circuiting and flowing out under centrifugal force, thereby ensuring the formation of a stable liquid film on the disk surface.

[0024] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. The above preferred embodiments of the present invention are not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
