Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production equipment technology, and in particular to a high-precision gas-liquid separation and purification device. Background Technology

[0002] In pharmaceutical manufacturing, the handling of gas-liquid mixtures is a crucial step. Many pharmaceutical processes, such as fermentation, distillation, and concentration, produce gas-liquid mixtures. These mixtures may contain microorganisms, particulate impurities, and harmful volatile organic compounds (VOCs). Without effective separation and purification, these mixtures can not only affect the quality and safety of the drugs but also corrode and damage production equipment, increasing production costs. Currently, existing gas-liquid separation and purification technologies and equipment have some shortcomings, as follows: Traditional purification devices use simple gravity settling or cyclone separation principles, which have low gas-liquid separation efficiency and are difficult to remove tiny droplets and impurity particles, thus reducing the quality of gas-liquid separation. Existing equipment is also prone to component wear during long-term operation, increasing the frequency of separator replacement. Furthermore, the wire mesh demister is secured by bolts, and when the bolts loosen, the gas-liquid separation effect can easily decrease, affecting the continuity and stability of production. Utility Model Content

[0003] This utility model relates to a high-precision gas-liquid separation and purification device. The airflow and moisture in the gas pipe impact the inclined block at the bottom of the separator, driving the separator to rotate and further swirling and separating the moisture in the airflow. The separated moisture passes through the impurity filter hole at the bottom edge of the separator, and after passing through the stabilizing sleeve at the bottom of the tank to filter impurities, it is discharged outward. The gas that has been initially separated by the separator moves upward and passes through the wire mesh demister in the positioning housing to further remove tiny droplets and impurities in the gas, achieving high-precision gas-liquid separation and purification. If the wire mesh demister needs to be disassembled for cleaning or replacement, push the anti-loosening block upward to release the lock on the nut, and then unscrew the nut to remove the wire mesh demister.

[0004] This utility model provides a high-precision gas-liquid separation and purification device, specifically including: a tank body, a set of support legs at the bottom of the tank body, an air inlet pipe on one side of the tank body, a separator installed inside the tank body, a friction cover above the separator, a wire mesh demister installed on the inner side of the positioning housing at the stepped groove position, a set of through holes opened at the edge of the wire mesh demister, a vertical threaded rod inserted inside the through holes, a set of vertical positioning rods at the top of the positioning housing, the positioning rods are cylindrical structures, an anti-loosening block is installed on the outer side of the positioning rods, a connecting flange is provided on one side of the air inlet pipe and one side of the positioning housing, and an impurity discharge pipe is provided on one side of the tank body.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1 to 9 : This invention proposes a high-precision gas-liquid separation and purification device, comprising: a tank body 1, with a set of supporting legs at the bottom of the tank body 1, and an air inlet pipe 101 on one side of the tank body 1. The air inlet pipe 101 has a bent structure, and inside the air inlet pipe 101 is a set of guide blocks 103 arranged in a circular array. The guide blocks 103 have an arc structure. When air containing moisture enters the interior of the air inlet pipe 101, the guide blocks 103 guide the airflow and moisture, causing the airflow and moisture to form a swirling flow. Therefore, by utilizing the centrifugal force generated by the swirling flow, the moisture in the airflow can be initially separated from the air, improving the efficiency of gas-liquid separation. Moreover, this swirling flow is naturally formed through structural design. This method eliminates the need for additional power equipment, reducing energy consumption and equipment costs. A return bend 102 is provided between the tank 1 and the air inlet pipe 101. The upper part of the return bend 102 is connected to the air inlet pipe 101, and the bottom of the return bend 102 is connected to the inside of the tank 1. The air inlet pipe 101 has an upward inclined structure near the tank 1. Therefore, some water will flow back into the inside of the return bend 102 under the separation of the swirling flow. Thus, this design further enhances the gas-liquid separation effect, allowing the separated water to flow back into the tank 1 in a timely manner, preventing water from mixing with the airflow again, ensuring that the gas entering the subsequent separation stage is drier, and improving the overall gas-liquid separation accuracy. In this embodiment, a separator 3 is installed inside the tank 1. A friction cover is provided above the separator 3 to protect the top of the separator 3. A pusher seat 303 is located above the separator 3, and a set of inclined blocks is located at the bottom of the pusher seat 303. The airflow and moisture inside the air inlet pipe 101 impact the inclined blocks, causing the separator 3 to rotate and separate the moisture in the airflow through a swirling motion. Therefore, the separator 3 is driven to rotate by the impact force of the airflow and moisture itself, realizing an automated swirling separation process, further enhancing the gas-liquid separation effect. No additional drive device is required, simplifying the equipment structure, while improving the stability and continuity of separation. A stabilizing sleeve is provided at the bottom of the inner side of the tank 1. A set of flow holes is opened on the base. A rotating groove is opened at the middle position of the bottom of the separator 3. The upper part of the stabilizing sleeve extends into the interior of the rotating groove. The stabilizing sleeve laterally positions the rotating position of the separator 3. An annular groove is opened on the inner side of the rotating groove. A bearing 301 is installed inside the annular groove. The specific model of the bearing 301 is selected according to actual needs so that the bearing 301 can correspond to the annular groove. The inner side of the bearing 301 contacts the outer wall of the stabilizing sleeve. With the cooperation of the bearing 301, the separator 3 can rotate smoothly. Therefore, the stability and smoothness of the separator 3 during the rotation process are ensured, the impact of rotation jamming or deviation on the gas-liquid separation effect is reduced, the separation work is guaranteed to be efficient, and the service life of the separator 3 is extended. In this embodiment, a set of ball bearings 302 arranged in a ring array are installed at the bottom of the separator 3. An annular groove corresponding to the ball bearings 302 is opened at the bottom of the tank 1. The bottom of the ball bearings 302 extends into the interior of the annular groove. The annular groove laterally positions the ball bearings 302. The arrangement of the ball bearings 302 reduces the friction of the separator 3 when it rotates, thus reducing the energy required for the separator 3 to rotate and further improving the efficiency of the equipment. At the same time, it reduces the wear between the separator 3 and the bottom of the tank 1, which is conducive to the long-term stable operation of the equipment and reduces maintenance costs. A set of impurity filter holes are opened at the edge of the bottom of the separator 3. The separated water passes through the impurity filter holes and enters the stabilizing sleeve of the tank 1. The impurity filter holes filter the impurities in the water. The filtered water is discharged outward through the stabilizing sleeve. Therefore, while realizing gas-liquid separation, it can also filter impurities in the separated water, further improving the purification effect, avoiding the accumulation of impurities inside the equipment and affecting the equipment performance, ensuring the purity of the discharged liquid, and making the function of the equipment more complete. In this embodiment, a wire mesh demister 4 is installed on the inner side of the positioning housing 2 at the stepped groove position. A set of through holes is opened at the edge of the wire mesh demister 4, and a vertical threaded rod 5 is inserted into the through holes. A set of vertical positioning rods 201 are provided at the top of the positioning housing 2. The positioning rods 201 are cylindrical structures. An anti-loosening block 6 is installed on the outer side of the positioning rods 201. A connecting flange is provided on one side of the air inlet pipe 101 and the positioning housing 2. An impurity discharge pipe is provided on one side of the tank body 1. A rotating hole is opened on one side of the anti-loosening block 6. The anti-loosening block 6 passes through the interior of the rotating hole. With the cooperation of the rotating hole, the anti-loosening block 6 can move up and down and circumferentially. A nut is installed above the 5, and tightening the nut locks the wire mesh demister 4 in place. A corresponding slot is provided on one side of the anti-loosening block 6. The anti-loosening block 6, in conjunction with the slot, prevents the threaded rod 5 and nut from loosening. Pushing the anti-loosening block 6 upwards unlocks the threaded rod 5 and nut. The anti-loosening block 6 effectively prevents stress deformation. Therefore, this design facilitates the installation and disassembly of the wire mesh demister 4, making maintenance and component replacement easier. It also ensures the stability of the wire mesh demister 4 during operation, preventing the nut from loosening and affecting the gas-liquid separation effect, thus improving the reliability and safety of the equipment.

[0022] Example 2, based on Example 1, such as Figures 1-6 As shown, separator 3 and wire mesh demister 4 are selected from existing high-precision filtration structures according to actual needs.

[0023] Example 3, based on Example 1, such as Figures 1-6 As shown, a valve is installed on the flange of the air inlet pipe 101 to control the gas flow rate.

[0024] The working principle of this embodiment: Place the tank 1 on a stable working surface using the support legs at the bottom. Select a suitable bearing 301 according to actual usage requirements and install it in the annular groove of the rotating groove at the bottom of the separator 3. Install the separator 3 inside the tank 1 so that the stabilizing sleeve at the bottom of the tank 1 extends into the rotating groove at the bottom of the separator 3. At the same time, allow the ball bearings 302 at the bottom of the separator 3 to fall into the corresponding annular groove at the bottom of the tank 1 to ensure that the separator 3 rotates smoothly and stably. Install the wire mesh demister 4 in the stepped groove position inside the positioning housing 2, pass the threaded rod 5 through the insertion hole on the edge of the wire mesh demister 4, install the nut above the threaded rod 5, and initially fix the wire mesh demister 4 by tightening the nut. Then pass the anti-loosening block 6 through the positioning rod 201 so that the slot of the anti-loosening block 6 corresponds to the nut, and push the anti-loosening block 6 to realize the anti-loosening locking of the threaded rod 5 and the nut. The existing air intake device is connected to the tank 1 via a connecting flange. The gas containing moisture is introduced into the tank 1 through the air intake pipe 101. After the gas enters the air intake pipe 101, the guide block 103 inside causes the airflow and moisture to form a swirling state. Some of the moisture is initially separated under the action of centrifugal force, and some of the moisture will flow back into the return bend 102 and flow into the tank 1 through the bottom of the return bend 102. The airflow and moisture in the inlet pipe 101 impact the inclined block at the bottom of the push seat 303 above the separator 3, driving the separator 3 to rotate and further swirling and separating the moisture in the airflow. The separated moisture passes through the impurity filter hole at the bottom edge of the separator 3, and is discharged after being filtered by the stabilizing sleeve at the bottom of the tank 1. The gas that has been initially separated by the separator 3 moves upward and passes through the wire mesh demister 4 in the positioning housing 2 to further remove tiny droplets and impurities from the gas, achieving high-precision gas-liquid separation and purification. If the wire mesh demister 4 needs to be disassembled for cleaning or replacement, push the anti-loosening block 6 upward to release the lock on the nut, and then unscrew the nut to remove the wire mesh demister 4. Observe the rotation of the separator 3. If the rotation is not smooth, check the wear of the ball bearing 302 and the bearing 301. If necessary, replace the worn parts in time to ensure the normal operation of the separator 3. When it is necessary to stop the gas-liquid separation, first close the air inlet valve of the inlet pipe 101 to stop the gas input.
