Specific embodiments

[0022] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0023] Embodiment 1

[0024] As Figure 1 - Figure 2 shown, the circulating heat exchange static disk includes a base plate 1 and a heat exchange part 2 provided on one surface in the thickness direction of the base plate 1, and a circulating heat exchange medium channel 3 is provided on the other surface in the thickness direction of the base plate 1. In this embodiment, by providing the circulating heat exchange medium channel 3 for heat exchange on the base plate 1, the temperature of the circulating heat exchange static disk can be changed. The base plate 1, the heat exchange part 2, and the circulating heat exchange medium channel 3 are connected by metal welding. Through the heat conduction between metals, the temperature of the heat exchange part 2 is adjusted by using the circulating heat exchange medium channel 3, which can fully reduce the requirement for the heat generated by the reaction of the multi-layer baffle type high gravity bed, and has great implementation value and social and economic benefits.

[0025] The circulating heat exchange medium channel 3 is any one of a spiral involute type disk-shaped channel and a wave ring type channel.

[0026] In this embodiment, the circulating heat exchange medium channel 3 is a spiral involute type disk-shaped channel, similar to a mosquito coil disk. Its advantage is that the diameter of the circulating medium channel is relatively thin and evenly distributed. The design of a relatively thin and evenly distributed diameter can increase the surface area of contact between the medium and the pipe wall, improve the heat transfer efficiency, and accelerate the heat transfer speed of the medium.

[0027] The outer edge of the bottom plate 1 is provided with an outer annular portion 30, and an inner annular portion 31 located inside the outer annular portion 30 is provided on the bottom plate 1. At least part of the circulating heat exchange medium channel 3 is connected to the outer annular portion 30, and at least part of the remaining circulating heat exchange medium channel 3 is connected to the inner annular portion 31. The outer annular portion 30 and the inner annular portion 31 jointly form a working space for heat transfer of the circulating heat exchange medium channel 3. At the same time, the settings of the outer annular portion 30 and the inner annular portion 31 improve the structural strength of the circulating heat exchange static disk and can adapt to stronger working intensity and operating temperature.

[0028] The circulating heat exchange medium channel 3 includes a clockwise sub-partition plate 32 in the shape of a spiral involute disk and a counterclockwise sub-partition plate 33 in the shape of a spiral involute disk. The inner end of the clockwise sub-partition plate 32 is connected to the inner annular portion 31. The inner end of the counterclockwise sub-partition plate 33 and the outer wall of the inner annular portion 31 are spaced apart. The counterclockwise sub-partition plate 33 and the clockwise sub-partition plate 32 are connected by a spiral cover plate 34 in the shape of a spiral involute. The clockwise sub-partition plate 32 and the counterclockwise sub-partition plate 33 form a clockwise sub-channel 320 and a counterclockwise sub-channel 330 with interconnected inner ends. In this embodiment, the circulating heat exchange medium channel 3 is composed of two spiral involute partition plates. Specifically, the two partition plates are the clockwise sub-partition plate 32 and the counterclockwise sub-partition plate 33 respectively. There are two circulating medium channels, namely the clockwise sub-channel 320 and the counterclockwise sub-channel 330, formed between the two partition plates. The two channels are interconnected at the inner end. The circulating medium first flows through the clockwise sub-channel 320 and then enters the counterclockwise sub-channel 330 from the inner end. The spiral cover plate 34 is used to seal the two circulating medium channels of the clockwise sub-channel 320 and the counterclockwise sub-channel 330 to prevent medium leakage and crosstalk between them.

[0029] The outer annular portion 30 is provided with an inlet 36 and an outlet 37 that communicate with the circulating heat exchange medium channel 3. The inlet 36 and the outlet 37 are respectively connected to an external medium circulation pump, so that during operation, the circulating heat exchange medium channel 3 can continuously have the medium circulating.

[0030] The inlet 36 and the outlet 37 are adjacent to each other and are misaligned in the circumferential direction of the outer annular portion 30 or are on the same circumferential line. This design is beneficial to optimizing the layout design of the circulating heat exchange static disk, so that the circulating heat exchange medium channel 3 can occupy a smaller material reaction space and obtain a greater reaction efficiency.

[0031] Embodiment Two

[0032] The structure and principle of this embodiment are basically the same as those of Embodiment One. The different structure lies in that for the circulating heat exchange medium channel in the above-mentioned Embodiment One, this embodiment provides a new form of the circulating heat exchange medium channel.

[0033] As Figure 3 - Figure 4As shown, the cyclic heat exchange medium channel 3 includes a number of inner baffles 310 that are distributed along the radial direction of the bottom plate 1 and whose inner ends are connected to the inner annular portion 31, and further includes a number of outer baffles 300 that are distributed along the radial direction of the bottom plate 1 and whose outer ends are connected to the outer annular portion 30. One outer baffle 300 is distributed between two adjacent inner baffles 310, and end closure plates 35 are respectively connected to the ends of the inner baffles 310, outer baffles 300, inner annular portion 31, and outer annular portion 30.

[0034] In this embodiment, the inner annular portion 31 and the outer annular portion 30 together form an annular circulating medium channel. Among them, the arrangement of the above-mentioned inner baffles 310 and outer baffles 300 makes the channel length of the cyclic heat exchange medium channel 3 longer, and at the same time increases the surface area of the medium in contact with the baffle surface, which helps to improve the heat transfer efficiency.

[0035] Two adjacent inner baffles 310 form a V-shaped space, and at least a part of the outer baffle 300 is inserted into the middle position of the V-shaped space. The function of the V-shaped space is to form vortices and turbulences of the circulating medium inside, and at the same time change the flow velocity of the medium, increasing the convective heat transfer effect. By increasing the disturbance and kinetic energy of the water flow, the heat transfer efficiency can be improved.

[0036] The length of the inner baffle 310 is shorter than the radial distance between the inner annular portion 31 and the outer annular portion 30, and the length of the outer baffle 300 is shorter than the radial distance between the inner annular portion 31 and the outer annular portion 30. The purpose is to prevent the inner baffle 310 and the outer baffle 300 from completely closing the flow channel of the circulating medium, avoiding the blockage and clogging of the medium in the local area. This helps to ensure the uniform flow of the medium and avoid the non-uniform heat transfer phenomenon caused by the too-fast or too-slow local medium flow velocity.

[0037] Embodiment Three

[0038] The structure and principle of this embodiment are basically the same as those of Embodiment One. The different structure lies in that for the cyclic heat exchange medium channel of the above-mentioned Embodiment One, the baffle type high gravity bed device of this embodiment includes a cyclic heat exchange medium channel.

[0039] The baffle type high gravity bed device of this embodiment is a gas-liquid contact device, which can be widely used in gas-liquid contact occasions such as absorption, rectification, chemical reaction, and nano-material preparation in industries such as chemical engineering, petrochemical engineering, biochemical engineering, pharmaceutical, metallurgy, and light industry.

[0040] The characteristics of the rotating bed in a supergravity field are its small volume, and it is hailed as the "transistor" in chemical engineering equipment. Before the present invention was made, most of the rotating beds in the prior art rotated with the entire rotor. Under centrifugal force far greater than gravity, gas and liquid made countercurrent contact inside the rotor. There are many kinds of structures inside the existing rotating bed rotors, but mainly porous medium packings such as wire meshes and plate packings. Due to the too short contact time of the gas-liquid phase in the packing, it is not conducive to the mass transfer between the gas-liquid phases. It is difficult for the liquid to be evenly distributed, resulting in gas-liquid short circuit or liquid channeling, which reduces the mass transfer efficiency. Since the rotor rotates with the shaft, it is very difficult for the existing rotating bed to achieve the problem of intermediate feeding in the continuous rectification operation of a single rotating bed. At least two rotating beds are required for continuous rectification operation.

[0041] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
