Description

Technical Field

[0001] This utility model relates to the field of environmental protection and chemical technology, specifically a gas-liquid coupler. Background Technology

[0002] A gas-liquid coupler is a specialized device that uses specific structural design and fluid mechanics principles to achieve efficient contact, mixing, mass transfer, or heat transfer between gas and liquid (referred to as "gas-liquid two-phase"). Its core function is to overcome the "boundary film resistance" at the contact point between the gas and liquid phases. By using forced disturbance, flow guidance, or swirling flow, it maximizes the gas-liquid contact area and extends the contact time, thereby enhancing the mass exchange (such as pollutant absorption, chemical reaction) or heat exchange between the two.

[0003] In traditional desulfurization towers, the raw material waste gas typically enters the bottom of the tower and is then contacted by the desulfurization liquid sprayed from the top of the tower in a countercurrent flow, thereby absorbing the harmful substances in the waste gas. However, in this process, the raw material waste gas rises rapidly and tends to accumulate on one side of the tower, resulting in low absorption efficiency and poor absorption effect.

[0004] Therefore, a gas-liquid coupler is proposed to address the above problems. It solves the issues of rapid rise of raw material and waste gas and easy accumulation of waste gas on one side of the tower, resulting in low absorption efficiency and poor absorption effect. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a gas-liquid coupler.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a gas-liquid coupler, comprising: a vortex module, characterized in that: an annular fixing frame is provided on the outer side of the vortex module, a groove is provided on the inner side of the annular fixing frame, a fan blade protection ring is provided in the groove, forward fan blades are evenly distributed on the inner side of the fan blade protection ring, the forward fan blades are installed on the outer side of the rotating slider, the rotating slider is located on the outer side of the auxiliary module, a groove is provided on the inner side of the auxiliary module, a fan blade protection ring is provided inside the groove, reverse fan blades are evenly distributed on the inner side of the fan blade protection ring, and a rotating shaft is provided at the center of the reverse fan blades.

[0007] Preferably, the swirling module is provided with a jetting module at its top.

[0008] Preferably, the jet module includes: a high-pressure atomizing nozzle, a high-pressure pipe, and a fixed base. The high-pressure atomizing nozzle is connected to the high-pressure pipe and is installed on the top of the fixed base.

[0009] Preferably, the swirl module has an auxiliary module inside.

[0010] Preferably, the auxiliary module includes: a first connecting rod, a second connecting rod, and a ring-shaped connecting frame, wherein the first connecting rod is connected to the outer side of the ring-shaped connecting frame, and the second connecting rod is connected to the inner side of the ring-shaped connecting frame.

[0011] Preferably, the annular fixing frame is connected to the annular connecting frame via a connecting rod one, and the rotating shaft is connected to the annular connecting frame via a connecting rod two.

[0012] The advantages of this utility model are:

[0013] This invention achieves a stable connection between the swirl module and the desulfurization tower through a ring-shaped fixing frame. Grooves one and two provide precise installation and positioning for the blade protection rings one and two, preventing component misalignment during operation. The forward and reverse blades form an inner and outer double-layer swirl field, and the rotating slider can flexibly adapt to different flue gas velocities, significantly enhancing the gas-liquid turbulence intensity and breaking the gas-liquid boundary film resistance. Integrating the jet module at the top of the swirl module allows the atomized liquid to be directly injected into the core area of ​​the double-layer swirl field, avoiding the problem of liquid falling before it is fully mixed, and significantly improving the gas-liquid contact time and area.

[0014] A central support frame is formed by an annular connecting frame. Connecting rod one and connecting rod two achieve multi-point connection with the outer annular fixed frame and the inner rotating shaft, respectively, which disperses the stress generated during operation and avoids structural damage caused by excessive local stress. The modular connecting rod design facilitates disassembly and maintenance, reducing equipment maintenance costs. Fan blade protection ring one and fan blade protection ring two can reduce the wear of the fan blades by gas-liquid impact, extend the service life of components, and at the same time ensure that the fan blades are evenly arranged to maintain a stable swirling effect. This ensures that the forward and reverse fan blades maintain precise relative positions during high-speed operation and maintain the stability of the double-layer swirling field.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a gas-liquid coupler, comprising: a swirl module 1, characterized in that: an annular fixing frame 11 is provided on the outer side of the swirl module 1, a groove 12 is provided on the inner side of the annular fixing frame 11, a blade protection ring 13 is provided in the groove 12, forward blades 14 are evenly distributed on the inner side of the blade protection ring 13, the forward blades 14 are mounted on the outer side of a rotating slider 15, the rotating slider 15 is located on the outer side of an auxiliary module 3, a groove 16 is provided on the inner side of the auxiliary module 3, a blade protection ring 17 is provided inside the groove 16, and reverse blades 18 are evenly distributed on the inner side of the blade protection ring 17. The center is equipped with a rotating shaft 19, which achieves a stable connection between the swirl module 1 and the desulfurization tower through the annular fixing frame 11. The groove 12 and groove 2 16 provide precise installation and positioning for the blade protection ring 13 and blade protection ring 2 17, preventing component displacement during operation. The rotating slider 15 can flexibly adapt to different flue gas velocities, greatly enhancing the gas-liquid turbulence intensity while effectively reducing the flue gas rising speed. The forward blade 14 and the reverse blade 18 can form an inner and outer double-layer swirl field, thereby making the flue gas distribution more uniform and increasing the contact time between the flue gas and the desulfurization liquid, thus increasing the contact area.

[0025] The annular connecting frame 11 forms a central support skeleton, and the connecting rods 1 and 2 respectively achieve multi-point connection with the outer annular fixed frame 11 and the inner rotating shaft 19, thus dispersing the stress generated during operation and avoiding structural damage caused by excessive local stress. The modular connecting rod design facilitates disassembly and maintenance, reducing equipment maintenance costs. The fan blade protection ring 13 and fan blade protection ring 2 17 can reduce the wear of the fan blades by gas-liquid impact, extend the service life of components, and at the same time ensure that the fan blades are evenly arranged to maintain a stable swirling effect, ensuring that the forward fan blade 14 and the reverse fan blade 18 maintain accurate relative positions during high-speed operation and maintain the stability of the double-layer swirling field.

[0026] Working principle: When the flue gas enters the swirl module (1) from the bottom or side of the coupler, the inner and outer fan blades work together to form a differentiated swirl. The flue gas first contacts the positive fan blade (14) inside the fan blade protection ring (13). The positive fan blade 14 rotates clockwise under the impact of the airflow, thereby applying a tangential force to the flue gas and forcing the flue gas to make an "outer spiral upward movement" along the inner side of the annular fixed frame. At the same time, the fan blade protection ring (13) is embedded in the groove (12) to avoid the fan blade from shifting due to the impact of the airflow and to ensure the stability of the outer swirl. The flue gas, which has been initially disturbed by the outer swirl, enters the inner area of ​​the auxiliary module 3 and contacts the reverse fan blade (18) inside the fan blade protection ring (17). The reverse fan blade 18 rotates passively with the airflow, applying a tangential force opposite to that of the forward fan blade 14, causing the inner flue gas to form a "spiral upward motion opposite to the outer layer's rotation direction"; at the same time, the positioning effect of the groove 2 (16) on the fan blade protection ring 2 (17) ensures that the inner swirling flow and the outer swirling flow are coaxial, avoiding flow field turbulence. Then, the desulfurization liquid is sprayed out in an atomized state by the jet module (2), and the atomized droplets enter the double-layer swirling flow field, achieving efficient coupling under the dual action of the outer and inner swirling flows.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
