Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, specifically to a gas-liquid separator for chemical production. Background Technology

[0002] In chemical production processes, gas-liquid separators are often used to separate the gas-liquid mixture to obtain separate liquid and gas phases, which are then sent to other corresponding processes.

[0003] For example, CN 222034189 U discloses a gas-liquid separator, which includes a shell with a gas-liquid separation chamber. The shell also has a gas-liquid mixed-phase inlet, a liquid phase outlet, and a gas phase outlet communicating with the gas-liquid separation chamber. The gas-liquid mixed-phase inlet is located at the top of the shell, the liquid phase outlet is located at the bottom of the shell and opposite to the gas-liquid mixed-phase inlet, and the gas phase outlet is located below the gas-liquid mixed-phase inlet. An anti-vortex disk is disposed within the gas-liquid separation chamber, and the anti-vortex disk's abutting surface is perpendicular to the axis between the gas-liquid mixed-phase inlet and the liquid phase outlet. The anti-vortex disk is positioned close to the liquid phase outlet relative to the gas-liquid mixed-phase inlet, so that the anti-vortex disk is below the liquid surface within the gas-liquid separation chamber to prevent the formation of vortices. This separator solves the problem of gas entrainment caused by vortices generated by the falling liquid releasing energy during the process. However, the gas-liquid separation path is limited by the equipment height, and the separation effect needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a gas-liquid separator for chemical production that has a reasonable structure and reliable operation, which solves the problem of poor separation effect due to the limitation of the separation path by the height of the equipment, and significantly enhances the separation effect.

[0005] The technical solution of this utility model is:

[0006] A gas-liquid separator for chemical production includes a vertical separation tank. The key technical features are: a concentric separation pipe is centrally located in the vertical separation tank; the top of the concentric separation pipe protrudes beyond the top surface of the vertical separation tank, and the bottom extends towards the bottom surface of the vertical separation tank while maintaining a predetermined distance; a concentric isolation sleeve is provided between the vertical separation tank and the concentric separation pipe; an annular bottom plate connects the lower edge of the concentric isolation sleeve to the inner circumferential wall of the vertical separation tank; an overflow chamber is formed between the concentric isolation sleeve and the vertical separation tank; and an upward flow channel is formed between the concentric isolation sleeve and the concentric separation pipe. A feed pipe is fixed to the top surface of the concentric separation pipe, and the inner end of the feed pipe extends to the middle of the concentric separation pipe. A first exhaust pipe is provided on the top side of the concentric separation pipe, and an anti-vortex plate is supported at the center of the lower end of the concentric separation pipe. Multiple ultrasonic transmitters are provided on the bottom surface of the vertical separation tank, and each ultrasonic transmitter is connected to an ultrasonic generator on the outside of the vertical separation tank. A second exhaust pipe is provided on the top side of the vertical separation tank, and a first drain pipe connected to the lower part of the overflow chamber is provided on the outside of the vertical separation tank. A second drain pipe is also provided at the bottom of the vertical separation tank.

[0007] In the aforementioned gas-liquid separator for chemical production, the outer ends of the first exhaust pipe and the second exhaust pipe are respectively connected to a vacuum pumping pipe.

[0008] In the aforementioned gas-liquid separator for chemical production, a cross-shaped flow divider is built into the lower end of the concentric separation pipe, and the anti-vortex plate is fixed at the center of the upper end of the cross-shaped flow divider. Multiple connecting ribs are fixed between the lower outer wall of the concentric separation pipe and the vertical separation tank to increase structural stability.

[0009] In the aforementioned gas-liquid separator for chemical production, a gas-phase annular rising space is formed between the feed pipe and the concentric separation pipe. The gas-phase annular rising space is provided with multiple baffle rings at intervals from bottom to top, and each baffle ring forms an S-shaped rising channel in the gas-phase annular rising space. The baffle rings are provided with air passage holes, and the first exhaust pipe is connected to the space above the highest baffle ring.

[0010] In the aforementioned gas-liquid separator for chemical production, the ultrasonic transmitter head is divided into two groups: one group of transmitter ports faces the inner side of the concentric separation pipe, and the other group of transmitter ports faces the upper baffle channel.

[0011] The beneficial effects of this utility model are:

[0012] 1. By adding an ultrasonic generator and a first and second exhaust pipe connected to a vacuum pipe, the gas phase in the gas-liquid mixture is quickly extracted. Each ultrasonic transmitter connected to the ultrasonic generator emits ultrasonic waves into the liquid, causing the gas phase in the liquid phase to gather and overflow onto the liquid surface, thereby enhancing the gas-liquid separation effect.

[0013] 2. The vertical separator is equipped with concentric separation pipes and concentric isolation sleeves, which sequentially form a downward, upward, and downward separation path in the vertical separator. With the equipment height remaining unchanged, the separation path is extended, thereby enhancing the gas-liquid separation effect. Attached Figure Description

[0017] The present invention will be described in detail with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 As shown, the gas-liquid separator for chemical production includes a vertical separation tank 4.

[0019] The vertical separator 4 has a concentric separation pipe 15 at its center. The top of the concentric separation pipe 15 protrudes from the top surface of the vertical separator 4, and the bottom extends towards the bottom surface of the vertical separator 4 while maintaining a set distance. A concentric isolation sleeve 6 is provided between the vertical separator 4 and the concentric separation pipe 15. An annular bottom plate is connected between the lower edge of the concentric isolation sleeve 6 and the inner peripheral wall of the vertical separator 4. An overflow chamber 7 is formed between the concentric isolation sleeve 6 and the vertical separator 4, and an upward flow deflection channel 16 is formed between the concentric isolation sleeve 6 and the concentric separation pipe 15.

[0020] The top surface of the concentric separation pipe 15 is fixed with a feed pipe 1, and the inner end of the feed pipe 1 extends to the middle of the concentric separation pipe 15. A first exhaust pipe 3 is provided on the top side of the concentric separation pipe 15. In this embodiment, a gas phase annular rising space 2 is formed between the feed pipe 1 and the concentric separation pipe 15. The gas phase annular rising space 2 is provided with multiple baffle rings 17 at intervals from bottom to top, and each baffle ring 17 forms an S-shaped rising channel in the gas phase annular rising space. Each baffle ring 17 is provided with an air passage hole 18. The first exhaust pipe 3 is connected to the space above the highest baffle ring 17.

[0021] The lower center of the concentric separation pipe 15 is supported by an anti-vortex disc 14. In this embodiment, the lower end of the concentric separation pipe 15 has a built-in cross-shaped flow divider 13, and the anti-vortex disc 14 is fixed at the upper center of the cross-shaped flow divider 13. Multiple connecting ribs 9 are fixed between the lower outer wall of the concentric separation pipe 15 and the vertical separation tank 4 to increase structural stability.

[0022] The bottom surface of the vertical separation tank 4 is provided with multiple ultrasonic transmitters 10, and each ultrasonic transmitter 10 is connected to an ultrasonic generator 11 on the outside of the vertical separation tank 4. In this embodiment, the ultrasonic transmitters 10 are divided into two groups, one group of transmitters facing the inside of the concentric separation pipe 15, and the other group of transmitters facing the upper baffle channel 16.

[0023] The vertical separation tank 4 is provided with a second exhaust pipe 5 on the top side. In this embodiment, the outer ends of the first exhaust pipe 3 and the second exhaust pipe 5 are respectively connected to a vacuum pipe.

[0024] The vertical separator 4 is provided with a first drain pipe 8 on the outside, which is connected to the lower part of the overflow chamber 7, and a second drain pipe 12 is provided at the bottom of the vertical separator 4.

[0025] Working principle:

[0026] When in use, start the ultrasonic generator 11 and the vacuum pumping unit connected to the vacuum pumping pipeline.

[0027] A gas-liquid mixture is fed into the concentric separation pipe 15 through the feed pipe 1. During the descent of the gas-liquid mixture, the entrained gas phase overflows from the liquid phase under the negative pressure of the vacuum pipe and moves towards the annular rising space of the gas phase. After passing through the rising channel formed by multiple baffle rings 17, it is discharged into the vacuum pipe through the first exhaust pipe 3. Meanwhile, the liquid phase falls into the vertical separation tank 4 through the cross-shaped diverter 13. The liquid level in the vertical separation tank 4 gradually rises to the upper edge of the concentric isolation sleeve 6, then overflows into the overflow chamber 7, and finally is discharged through the first drain pipe 8. During the above operation, each ultrasonic transmitter 10 connected to the ultrasonic generator 11 emits ultrasonic waves into the liquid, causing the remaining gas in the liquid phase to accumulate and overflow to the liquid surface, and finally be discharged into the vacuum pipe through the first exhaust pipe 3 and the second exhaust pipe 5. After the operation is completed, the remaining liquid phase in the vertical separation tank 4 is discharged through the second drain pipe 12.

[0028] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
