[0002] In fields such as chemical experiments, environmental monitoring, and new material research and development, it is often necessary to absorb or purify small amounts of gas. While traditional tower absorbers offer stable absorption, they are typically bulky, complex in structure, expensive, and require significant amounts of absorbent, making them unsuitable for the small-batch, multi-batch, and easily operable needs of laboratory experiments. Therefore, developing a compact, easy-to-operate, highly efficient, and suitable small-scale absorber for laboratory environments is of significant practical importance. Utility Model Content

[0009] Preferably, the second atomizing nozzle, the main pipe, and the air inlet work together to form a gas-liquid premixing vortex generator; after the gas enters the main pipe at an angle of ° through the air inlet, it is immediately impacted and enveloped by the liquid droplets atomized by the second atomizing nozzle, forming a high-speed rotating gas-liquid mixing vortex before entering the wire mesh packing area.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments; Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Reference Figure 1The specific embodiment adopts the following technical solution: a small separation absorber for use in the laboratory to replace a tower absorber, including a tower body 1 and a tower top 2. The tower body 1 is fixedly connected to the tower top 2 through a flange 3. An eluent 4 is provided in the lower middle part of the tower body 1. A wire mesh packing 5 is provided above the eluent 4. A first atomizing nozzle 6 is provided above the wire mesh packing 5. The first atomizing nozzle 6 is connected to a replenishment port N9 through a pipe. A vacuum outlet N1 is provided on one side of the top of the tower top 2. A main pipe 8 is provided on the other side of the top of the tower top 2 through a first jacket 7. A second atomizing nozzle is connected to the top of the main pipe 8. The second atomizing nozzle 9 is connected to the atomizing spray port N8, which serves as the circulation inlet. An air inlet N2 is provided on one side below the second atomizing nozzle 9. The upper and lower parts of the first jacket 7 are respectively provided with a first jacket outlet N5b and a first jacket inlet N5a. The bottom of the main pipe 8 extends into the eluent 4. A second jacket 10 is provided on the outside of the tower body 1. The lower part of the second jacket 10 is connected to the frame 11. From top to bottom, the second jacket 10 is provided with an exhaust hole N10 at the top, a second jacket outlet N4b, a liquid level switch port N6, and a second jacket inlet N4a.

[0018] It is worth noting that the air inlet N2 forms an 85° angle with the central axis of the main pipe 8.

[0019] It is worth noting that a discharge port N3 is provided at the center of the bottom of the tower body 1, and a circulation outlet N7 is provided on one side of the bottom of the tower body 1.

[0020] It is worth noting that the air inlet N2 is connected to the pyrolysis furnace.

[0021] It is worth noting that the first jacket 7 and the second jacket 10 can be independently supplied with temperature control media of different temperatures, forming independent temperature control for the gas-liquid mixing area at the air inlet N2 and the main absorption area inside the tower body 1; the temperature of the temperature control media in the first jacket 7 is lower or higher than the temperature of the temperature control media in the second jacket 10.

[0022] In addition, the second atomizing nozzle 9, the main pipe 8 and the air inlet N2 work together to form a gas-liquid premixing vortex generator; after the gas enters the main pipe 8 at an angle of 85° through the air inlet N2, it is immediately impacted and enveloped by the liquid droplets atomized by the second atomizing nozzle 9, forming a high-speed rotating gas-liquid mixing vortex before entering the wire mesh filler 5 area.

[0023] The working principle of this specific implementation method is as follows: Phase 1: Intake and Turbulence Enhancement Premixing Inlet: The gas to be treated (e.g., high-temperature exhaust gas from the pyrolysis furnace) enters the main pipe (8) at a high speed at a specific angle of 85° through the inlet (N2).

[0024] Vortex generation: This 85° angle of entry is key to the formation of vortices. After the gas enters the main pipe, its flow direction is forced to change, generating a strong spiral motion along the pipe wall, forming a high-speed rotating cyclone.

[0025] Premixing and initial absorption: Simultaneously, the absorbent (which can be fresh or recycled) is supplied to the second atomizing nozzle 9 located at the top of the main pipe through the atomizing spray port N8, which serves as the circulation inlet. The second atomizing nozzle atomizes the absorbent into extremely fine droplets, which are then sprayed downwards into the main pipe.

[0026] Synergistic effect: The high-speed rotating cyclone violently collides, cuts, and encapsulates the falling atomized droplets. The second atomizing nozzle 9, the main pipe 8, and the air inlet N2 work together to form a highly efficient "gas-liquid premixing vortex generator." In this process, the target components in the gas complete the first rapid and efficient mass transfer and absorption with the absorbent liquid before entering the main absorption zone.

[0027] Pre-zone temperature control: To optimize the absorption efficiency at this stage, the first jacket 7 can be independently circulated with a temperature-controlled medium. For example, if the inlet temperature is too high, a cooling medium can be introduced to cool the premixed zone and prevent high temperatures from affecting the activity of the absorbent or causing side reactions.

[0028] Phase Two: Main Absorption and Deep Purification Entering the main body: The premixed gas-liquid mixture is ejected from the bottom outlet of the main pipe 8 and enters the wire mesh packing 5 area of ​​the tower body 1.

[0029] Deep absorption: Wire mesh packing has a huge specific surface area and a complex pore structure. The gas-liquid mixture constantly changes its flow direction and velocity in the packing layer, and the liquid film is constantly renewed and broken on the packing surface, which greatly prolongs the gas-liquid contact time and realizes a second, deeper mass transfer, further absorbing the target components remaining in the gas.

[0030] Countercurrent spraying: Simultaneously, another stream of absorbent is supplied through atomizing spray nozzle N8 to the first atomizing nozzle 6 located above the packing material. The first atomizing nozzle continuously sprays and wets the packing layer from top to bottom. This top-down liquid flow and bottom-up airflow form a classic gas-liquid two-phase countercurrent contact, ensuring efficient mass transfer throughout the packing layer and maximizing the absorption driving force.

[0031] Main body temperature control: The temperature of the entire tower body 1 and the eluent 4 inside is precisely controlled by the second jacket 10. Through the circulation of temperature-controlled media via its inlet N4a and outlet N4b, the main absorption zone is maintained at the optimal chemical reaction temperature, ensuring the high efficiency and stability of the absorption reaction.

[0032] Phase 3: Product Separation and Recycling Gas discharge: After two stages of enhanced absorption, the gas that meets the purification standard continues to rise to the top of the tower 2, and is finally extracted through the vacuum outlet N1.

[0033] Liquid circulation and discharge: The liquid that has absorbed the target substance (i.e., eluent 4) collects at the bottom of the tower due to gravity.

[0034] Recycling: In order to save costs, most of the eluent can be extracted through the bottom circulation outlet N7, pressurized by an external pump, and sent back to the circulation inlet N8 to participate in the first stage of premixing again, forming a closed loop.

[0035] Discharge or replacement: When the eluent concentration is saturated or needs to be replaced, it can be completely discharged from the discharge port N3 at the center of the bottom of the column.

[0036] Through the close coordination of the above three stages, this invention achieves efficient gas purification within a compact volume. Its unique vortex premixing design and zoned temperature control function make it far superior to traditional small absorption devices in terms of processing efficiency and operational flexibility, perfectly solving the practical needs of small-scale laboratory experiments.

[0037] 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.
