Description

Technical Field

[0001] This utility model belongs to the field of static mixing, specifically, it relates to a three-phase mass exchanger for thorough mixing of solid, liquid and gas. Background Technology

[0002] Three-phase mass transfer refers to the process by which gas, liquid, and solid phases are transferred between interfaces through diffusion, convection, or chemical reactions. Its core lies in optimizing the contact and mixing of the gas, liquid, and solid phases to efficiently achieve the migration, transformation, or separation of substances.

[0003] Chinese Patent No. 200710175802.6 discloses a pneumatic desulfurization unit for a wet flue gas desulfurization device, comprising, from top to bottom, a mixing container that serves to mix gas and liquid and to act as a channel for emitting purified gas, a hydrocyclone that serves to change the direction of airflow, and a cone that serves as a gas inlet and a slurry outlet. The mixing container and the hydrocyclone, as well as the hydrocyclone and the cone, are all connected by bolts or welding.

[0004] When this utility model is in use, the container is a single unit, and after a long period of use, the material adhering inside is difficult to clean. After damage occurs inside the device, repair and replacement are very inconvenient.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a three-phase mass exchanger for thorough mixing of solid, liquid and gas.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A three-phase mass transfer exchanger for thorough mixing of solid, liquid, and gas includes an exchange device. The exchange device consists of multiple exchanger units, a feeding mechanism, and a discharge pipe. The feeding mechanism is installed at the upper end of each exchanger unit. Each exchanger unit consists of a mounting plate, a mounting cylinder, and a cutting plate. The cutting plate is welded inside the mounting cylinder, and the mounting plates are welded to both sides of the mounting cylinder. The mounting plates are fixed together by a fixing mechanism.

[0009] Optionally, the feeding mechanism consists of a feeding pipe, an air inlet pipe, and a liquid inlet pipe. The feeding pipe is installed at the upper end of the exchange device, the air inlet pipe is installed on one side of the upper end of the feeding pipe, and the liquid inlet pipe is installed on one side of the lower end of the feeding pipe.

[0010] Optionally, an air intake control valve is installed on the upper side of the air intake pipe, and a liquid intake control valve is installed on the upper side of the liquid intake pipe.

[0011] Optionally, the installation mechanism consists of an annular fixing sleeve and a fixing plate, wherein the fixing plate is welded to both sides of the annular fixing sleeve, and the fixing plates are fixedly connected to each other by bolts.

[0012] Optionally, a rubber pad is provided on the inner side of the annular fixing sleeve, and the rubber pad is attached to the inside of the annular fixing sleeve with adhesive.

[0013] Optionally, a self-cleaning layer is provided inside the mounting cylinder and outside the cutting plate, and the self-cleaning layer is a nano-silicon coating layer.

[0014] Optionally, by adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. The switching unit consists of multiple individual switches. The number of individual switches can be increased according to usage requirements, thereby adjusting the mixing efficiency of the switching unit. At the same time, it is convenient to maintain the switching unit, and if damage occurs, there is no need to replace the entire switching unit.

[0016] 2. The feed pipe is installed at the top of the exchanger and is mainly responsible for conveying solid or granular materials into the exchanger. The air inlet pipe is installed on one side above the feed pipe. When it is necessary to introduce reaction gas, protective gas, or to adjust the composition of the ambient gas into the exchanger, the gas enters through the air inlet pipe. The position design of the air inlet pipe and the feed pipe allows the gas to quickly come into contact with and mix with the material entering from the feed pipe after entering the exchanger. The liquid inlet pipe is installed on one side below the feed pipe and is used to convey liquid materials. After the liquid enters from the liquid inlet pipe, it will fully interact with the material and gas in the exchanger unit according to its own gravity and the flow field distribution in the device, so as to realize the processes of material exchange and reaction.

[0017] 3. The annular retaining sleeve is mainly used to fit over the mounting plate of the unit exchanger that needs to be fixed, serving to hold and position it. The retaining plate is welded to both sides of the annular retaining sleeve and connected together by bolts. During the tightening of the bolts, the annular retaining sleeve will gradually tighten, thereby firmly fixing the internal components. This installation method facilitates the installation and disassembly of components. When maintaining, repairing or replacing components, simply loosen the bolts to open the annular retaining sleeve and remove or replace the internal components.

[0018] 4. Nano-silicon coatings possess unique microstructures and chemical properties. During the operation of the exchange unit, when materials, gases, and liquids flow within the mounting cylinder and come into contact with the self-cleaning layer, the low surface energy of the nano-silicon coating prevents impurities and dirt from easily adhering to its surface. Even if a small amount of impurities adheres, they are easily carried away by the subsequent flushing action of materials, gases, and liquids. Furthermore, nano-silicon coatings may possess a certain degree of chemical stability, preventing chemical reactions with the materials, gases, and liquids within the exchange unit. This ensures the continued self-cleaning performance, reduces the frequency of manual cleaning, lowers equipment maintenance costs, maintains the cleanliness of the exchange unit's interior, preserves a good operating environment, and improves exchange efficiency and equipment lifespan.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this embodiment provides a three-phase mass transfer exchanger for thorough mixing of solid, liquid, and gas, including an exchange device 1. The exchange device 1 consists of multiple exchanger units 2, a feeding mechanism 10, and a discharge pipe 4. The feeding mechanism 10 is installed at the upper end of the exchanger unit 2. The exchanger unit 2 consists of a mounting plate 14, a mounting cylinder 15, and a cutting plate 16. The cutting plate 16 is welded inside the mounting cylinder 15, and the mounting plates 14 are welded to both sides of the mounting cylinder 15. The mounting plates 14 are fixed together by a fixing mechanism 3.

[0030] One application of this embodiment is as follows: The core of the exchange device 1 is the coordinated operation of multiple exchanger units 2. The feeding mechanism 10 is responsible for introducing the materials, gases, and liquids to be processed into the exchanger units 2. The feeding mechanism 10 is installed at the upper end of the exchanger unit 2, allowing the materials to smoothly enter the interior of the exchanger unit 2. The mounting plate 14 of the exchanger unit 2 serves to support and fix the mounting cylinder 15. The cutting plate 16 is welded inside the mounting cylinder 15, and its function is to divide the interior of the mounting cylinder 15 into different spatial areas, increasing the contact area and path length of the materials, gases, and liquids inside the cylinder. When the materials enter from the feeding mechanism 10... After entering the exchanger unit 2, it is guided by the cutting plate 16 inside the mounting cylinder 15 to more fully exchange substances with the gas and liquid entering from different paths. The mounting plates 14 are fixed by the fixing mechanism 3 to ensure that the entire exchanger unit 2 is structurally stable and that the components will not be displaced due to internal pressure or other factors during operation, thus affecting the exchange effect. The exchange device 1 is composed of multiple exchanger units 2, and the number of exchanger units 2 can be increased according to the usage requirements, thereby adjusting the mixing efficiency of the exchange device 1. At the same time, it is convenient to maintain the exchange device 1, and if damage occurs, there is no need to replace the entire exchange device 1.

[0031] In this embodiment, the feeding mechanism 10 consists of a feeding pipe 5, an air inlet pipe 6, and a liquid inlet pipe 9. The feeding pipe 5 is installed at the upper end of the exchange device 1, the air inlet pipe 6 is installed on one side of the upper end of the feeding pipe 5, and the liquid inlet pipe 9 is installed on one side below the feeding pipe 5. The feeding pipe 5, installed at the upper end of the exchange device 1, is mainly responsible for conveying solid or granular materials into the exchange device 1. The air inlet pipe 6, installed on one side of the upper end of the feeding pipe 5, allows gas to enter the exchange device 1 when it is necessary to introduce reaction gas, protective gas, or to adjust the composition of the ambient gas. The positions of the air inlet pipe 6 and the feeding pipe 5 are designed so that the gas can quickly come into contact with and mix with the material entering from the feeding pipe 5 after entering the exchange device 1. The liquid inlet pipe 9, installed on one side below the feeding pipe 5, is used to convey liquid materials. After the liquid enters from the liquid inlet pipe 9, it will fully interact with the material and gas in the exchanger unit 2 according to its own gravity and the flow field distribution in the device, realizing the processes of material exchange and reaction.

[0032] In this embodiment, an intake control valve 7 is installed on the upper side of the intake pipe 6, and a liquid control valve 8 is installed on the upper side of the liquid inlet pipe 9. The main function of the intake control valve 7 is to precisely control the flow rate, pressure, and on / off state of the gas entering the exchange device 1. By adjusting the opening of the intake control valve 7, the gas input can be flexibly adjusted according to the reaction process and material processing requirements within the exchange device 1. The liquid control valve 8 is used to control the flow rate, velocity, and on / off state of the liquid entering the exchange device 1. In some processes that require strict control of the amount of liquid added, the liquid control valve 8 can precisely adjust the liquid input to ensure that the reaction or mixing process between the liquid, materials, and gas proceeds as expected, and to avoid affecting the operating effect of the exchange device 1 due to too much or too little liquid.

[0033] In this embodiment, the installation mechanism consists of an annular fixing sleeve 12 and a fixing plate 11. The fixing plate 11 is welded to both sides of the annular fixing sleeve 12, and the fixing plates 11 are fixedly connected by bolts. The annular fixing sleeve 12 is mainly used to fit over the mounting plate 14 of the switch unit 2 that needs to be fixed, and plays a role in clamping and positioning. The fixing plate 11 is welded to both sides of the annular fixing sleeve 12 and connected together by bolts. During the tightening of the bolts, the annular fixing sleeve 12 will gradually tighten, thereby firmly fixing the internal components. This installation method facilitates the installation and disassembly of components. When maintaining, repairing or replacing components, simply loosen the bolts to open the annular fixing sleeve 12 and remove or replace the internal components.

[0034] In this embodiment, a rubber pad 13 is provided on the inner side of the annular fixing sleeve 12. The rubber pad 13 is attached to the inside of the annular fixing sleeve 12 with adhesive. The rubber pad 13 has good elasticity and friction. When the annular fixing sleeve 12 clamps the component, the rubber pad 13 can fill the tiny gap between the annular fixing sleeve 12 and the component, playing a sealing role and preventing dust, impurities, etc. from entering the fixed area and affecting the operation of the equipment. On the other hand, the elasticity of the rubber pad 13 can buffer the vibration and impact generated during the operation of the equipment, protecting the fixed component from damage. At the same time, the rubber pad 13 increases the friction between the annular fixing sleeve 12 and the component, making the fixation more secure and preventing the component from shifting due to vibration or other reasons during operation.

[0035] In this embodiment, a self-cleaning layer 17 is provided inside the mounting cylinder 15 and outside the cutting plate 16. The self-cleaning layer 17 is a nano-silicon coating layer. The nano-silicon coating has a special microstructure and chemical properties. During the operation of the exchange device 1, when materials, gases and liquids flow in the mounting cylinder 15 and come into contact with the self-cleaning layer, due to the low surface energy characteristics of the nano-silicon coating, some impurities and dirt are not easy to adhere to the surface of the self-cleaning layer. Even if a small amount of impurities adhere, they are easily carried away by the subsequent flushing action of materials, gases and liquids. In addition, the nano-silicon coating may also have a certain degree of chemical stability and will not react chemically with the materials, gases and liquids in the exchange device 1, thereby always maintaining self-cleaning performance, reducing the frequency of manual cleaning, reducing equipment maintenance costs, ensuring the cleanliness of the exchange device 1, maintaining a good operating environment, improving exchange efficiency and equipment lifespan.
