Description

Technical Field

[0001] This utility model belongs to the technical field of gas distributors, and in particular relates to a non-powered rotating gas distributor. Background Technology

[0002] In gas-liquid phase reactors, gas distributors are widely used. Their function is to mix the gas and liquid evenly, which is conducive to the chemical reaction and prevents the local concentration of a certain material from being too high, which would increase the number of side reactions.

[0003] Traditional gas distribution methods typically rely on mechanical stirrers to disperse the gas and agitate the liquid. However, mechanical stirrers have some drawbacks during operation, including:

[0004] High energy consumption: Mechanical mixers require an external power source, which increases energy consumption and operating costs.

[0005] Complex maintenance: The complex sealing design between the moving parts of the agitator and the reactor inlet makes it prone to leakage, increasing the difficulty and frequency of maintenance.

[0006] Uneven reaction: In some cases, the movement of the stirrer may cause uneven gas distribution, affecting the reaction effect and the quality of the product.

[0007] Large equipment size: Traditional mixers are usually large, which increases the footprint of the equipment and the difficulty of installation. Utility Model Content

[0008] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a non-powered rotating gas distributor.

[0009] To achieve the above objectives, the technical solution adopted is:

[0010] A non-powered rotary gas distributor includes a gas main pipe, the lower end of which is connected to a plurality of distributor branch pipes. The gas main pipe communicates with the inner cavities of the distributor branch pipes. The plurality of distributor branch pipes are radially distributed in a manner that allows them to rotate around the gas main pipe. Each distributor branch pipe is provided with a plurality of air holes, which are located on the side of the distributor branch pipe opposite to the direction of rotation.

[0011] The beneficial effects of adopting the above technical solution are as follows: the gas main pipe is connected to the inner cavity of multiple radially distributed and rotatable distributor branch pipes. That is, the pipe wall at the connection between the gas main pipe and the distributor branch pipes is provided with through holes. Gas enters the distributor branch pipe from the gas main pipe. The gas holes on the distributor branch pipes are located on the opposite side of the rotation direction. When the gas is ejected from the gas holes, according to the principle of reaction force, it will push the distributor branch pipe to rotate around the gas main pipe. During the rotation, the gas can be more widely dispersed into the surrounding space, so that the gas is more evenly distributed in the reaction liquid from the bottom in the form of bubbles in the gas-liquid phase reactor. The rotation of the distributor branch pipes can not only make the gas evenly distributed, but also stir the reaction liquid, increase the contact area and contact opportunities between the gas and liquid phases, and make it more conducive to the reaction between the gas and liquid phases.

[0012] Based on the above technical solution, the present invention can be further improved as follows:

[0013] Preferably, the distributor branch pipe is connected to the gas main pipe via a rotating disc.

[0014] More preferably, the rotating disc includes an upper disc and a lower disc, which are respectively disposed at the upper end and the lower end of the distributor branch pipe. An upper fixing member and a lower fixing member are respectively provided on the side of the upper disc and the lower disc away from the distributor branch pipe. A sealing assembly is provided between the upper fixing member and the upper disc and between the lower fixing member and the lower disc. The rotating disc, the upper fixing member, the lower fixing member and the sealing assembly are all sleeved on the outer periphery of the gas main pipe.

[0015] The advantages of adopting the above-mentioned preferred technical solution are as follows: the upper and lower fixing parts are used to fix the moving turntable and the distributor branch pipe to prevent them from being displaced in the vertical direction. A sealing component is provided between the upper fixing part and the upper plate and between the lower fixing part and the lower plate to prevent gas from leaking from the connection between the moving turntable and the fixing part, thus ensuring the sealing and stability of the gas delivery.

[0016] Preferably, the sealing assembly includes a rotating disc sealing ring, a sliding sealing ring, and a spring that are interconnected, and the rotating disc sealing ring, the sliding sealing ring, and the spring are arranged sequentially along a direction away from the distributor branch pipe.

[0017] The advantages of adopting the above-mentioned preferred technical solution are as follows: when the rotating disk sealing ring follows the rotating disk, it slides relative to the sliding sealing ring. The rotating disk sealing ring and the sliding sealing ring are preferably made of graphite, silicon carbide and other materials, which have low frictional resistance. The spring can provide a certain elastic pressure, so that the sliding sealing ring and the fixed part fit tightly, which enhances the sealing effect and further prevents gas leakage.

[0018] Preferably, the upper and lower fixing components are connected to the gas main pipe by bolts.

[0019] The advantages of adopting the above-mentioned preferred technical solution are: the bolt connection has high connection strength and stability, which can ensure the reliable connection between the fastener and the gas main pipe, guarantee the stability of the entire gas distributor structure, and prevent loosening or displacement during rotation.

[0020] Preferably, the distributor branch pipe is connected to the motion turntable via a threaded connection.

[0021] The advantages of adopting the above-mentioned preferred technical solution are: the threaded connection method facilitates the installation and disassembly of the distributor branch pipe and the moving turntable, and makes it convenient to replace, repair or clean the distributor branch pipe or the moving turntable, thereby improving the maintainability of the equipment.

[0022] Preferably, a distributor bracket is connected to the bottom end of the gas main.

[0023] The beneficial effects of adopting the above-mentioned preferred technical solution are as follows: the gas distributor support can provide support for the gas main pipe, enhance the stability of the entire gas distributor in the reactor, make it more stable during rotation, and reduce shaking and vibration.

[0024] More preferably, the height of the distributor bracket is adjustable.

[0025] The advantages of adopting the above-mentioned preferred technical solution are as follows: the height-adjustable distributor support allows the gas distributor to be adapted to reactors of various depths. For example, in a deeper reactor, raising the height of the support ensures that the distributor is in a suitable position, allowing the gas to be evenly distributed from the bottom into the reaction liquid in an ideal state. For a shallower reactor, lowering the height of the support avoids the distributor being too far or too close to the bottom of the reactor, ensuring the gas distribution effect and the normal progress of the reaction. At the same time, it also allows the distributor branches to be located at different depths within the same reactor, thereby further improving the uniformity and completeness of the gas-liquid reaction.

[0026] Preferably, the upper plate and the lower plate are connected.

[0027] The beneficial effects of adopting the above-mentioned preferred technical solution are as follows: the connection between the upper plate and the lower plate can make the moving turntable form a more complete and stable overall structure, improve the strength and rigidity of the moving turntable, better drive the distributor branch pipe to rotate, and at the same time help to ensure the sealing effect of the sealing component.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows: when the gas is sprayed out along the distributor, the moving parts of the distributor begin to rotate, so that the gas is evenly distributed in the reaction liquid from the bottom in the form of bubbles in the gas-liquid phase reactor. At the same time, due to the rotation of the moving parts, the bubble distribution is more uniform, and the reaction liquid is stirred, which is more conducive to the gas-liquid phase contact and reaction. In addition, the stirrer is eliminated, the gas main pipe is fixedly connected to the reactor inlet, and the moving sealing parts between the stirrer shaft and the reactor inlet are eliminated, reducing the risk of chemical leakage. It is adaptable to reactors of various depths, and the distributor branches can be located at different depths in the same reactor, thereby further improving the uniformity and completeness of the gas-liquid reaction.
