Description

Technical Field

[0001] This utility model relates to the field of hydrogen gas-liquid separation technology, and more specifically, to a hydrogen gas-liquid separator. Background Technology

[0002] Hydrogen separation technology is used in various industries, including chemical, light, new energy, lithium battery, and environmental protection. The design of the gas-liquid separator directly impacts the effectiveness of hydrogen separation. An improperly designed separator can lead to electrolyte waste, substandard hydrogen purity, and unusable separated products. Currently, some chemical plants use perforated pipes or trough-type diversion structures for separation. However, gas-liquid separation failure results in the waste of electrolyte and hydrogen, increases secondary recovery costs, and negatively impacts production quality. Cleaning equipment for gas-liquid separators is also very traditional, requiring disassembly and often relying on manual labor, which is inefficient. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hydrogen gas-liquid separator to solve one or more of the above-mentioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A hydrogen gas-liquid separator includes a separation tank welded from top to bottom by an upper end cap, a cylindrical body, a lower end cap, and support legs. A plate-shaped baffle distributor is provided inside the cylindrical body. The plate-shaped baffle distributor has a uniformly distributed three-pronged structure. Two of the plate-shaped baffle distributors have a first gas-liquid inlet and a second gas-liquid inlet, respectively. The other section of the plate-shaped baffle distributor is provided with a sealing plate. The cylindrical body has an inlet that connects to the first gas-liquid inlet and the second gas-liquid inlet on the plate-shaped baffle distributor. The upper end cap has a gas outlet at the top, the lower end of the cylinder has a condensate inlet, and the lower end cap has an electrolyte outlet at the bottom. The gas-liquid mixture enters the sheet baffle distributor from the feed port through the first gas-liquid inlet and the second gas-liquid inlet. After being uniformly dispersed and atomized, it flows into the separation tank and liquefies after contacting the condensate water introduced from the condensate inlet. It is then discharged from the electrolyte outlet. The separated gas is discharged from the gas outlet through the sheet baffle distributor.

[0005] Furthermore, the sidewalls of the two feed sections of the sheet-like baffle distributor converge regularly from the port to the connection center, and the sidewalls of the mating section of the sheet-like baffle distributor converge regularly from the connection center to the port.

[0006] Furthermore, the inclination of the lower baffle at the feeding section is 5°, and the inclination of the lower baffle at the mating section is 6°.

[0007] Furthermore, the interior of the two adjacent sides of the feeding sections is provided with curved guide plates, and the interior of the mating section and the adjacent sides of the two feeding sections is provided with a connecting plate.

[0008] Furthermore, the sheet-like baffle distributor is composed of an upper baffle, a side baffle, and a lower baffle. The sheet-like baffle distributor has through slots on both sides, and several square baffles are arranged symmetrically and at equal intervals in the through slots on both sides. The end of the square baffle near the connection center is offset outward.

[0009] Furthermore, the side baffles are provided on both sides of the two feed section ports, while the mating section port is not provided with the side baffles.

[0010] Furthermore, the square baffle is tilted at an angle of 80°, and the square baffle extends half its length beyond the sheet-like baffle distributor.

[0011] In summary, this invention offers the following advantages: By optimizing and improving the traditional distributor structure, a new plate-shaped baffle distributor is designed, increasing the number of gas-liquid inlets and improving the gas-liquid separation speed. The square baffles, in conjunction with other baffles, achieve uniform separation, improving the purity of the separated hydrogen. The electrolyte can be recycled for secondary gas-liquid separation, resulting in high utilization. The equipment only requires internal water washing followed by nitrogen purging; no disassembly of components is necessary. Attached Figure Description

Detailed Implementation

[0014] Example

[0015] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0016] A hydrogen gas-liquid separator, such as Figure 1 As shown, the main body is a separation tank, welded from top to bottom by an upper head 8, a cylinder 5, and a lower head 3 of corresponding dimensions. A gas outlet 10 is located at the center of the top of the upper head 8, from which the subsequently separated high-purity hydrogen gas is discharged. A pressure sensor port 9 and a safety valve port 12 are also located on the top of the upper head 8. The pressure sensor port 9 allows for the installation of a pressure sensor to monitor pressure changes within the equipment in real time. When the equipment is overpressurized, the safety valve connected to the safety valve port 12 automatically releases pressure, protecting the equipment's operational safety. The upper head 8 is also equipped with lifting lugs 11 for easy hoisting and disassembly. Support legs 2 are welded to the bottom of the lower head 3, and the support legs 2 have a grounding plate 1. An electrolyte outlet 19 is located at the center of the bottom of the lower head 3 for easy discharge of the separated electrolyte. The upper left side of the cylinder 5 has a liquid level sensor port 7 and a spare port 6. The liquid level sensor in port 7 detects the internal liquid level and controls the liquid level by controlling the flow rate of the gas-liquid inlet. The spare port 6 serves as a clean water inlet during subsequent process improvements and overhauls, accelerating the internal water storage and cleaning time and improving cleaning efficiency. The lower left side of the cylinder 5 has a nitrogen port 4. Nitrogen gas is introduced to purge the internal electrolyte after cleaning, keeping the equipment dry and clean, facilitating secondary electrolyte separation and other circulating operations. The upper right side of the cylinder 5 has an upper manhole 14 and a lower manhole 17, respectively, for easy inspection of the plate baffle distributor 13 and observation of the condensate inlet and outlet. The lower front of the cylinder 5 has a condensate inlet 18, and the upper front of the cylinder 5 has two feed inlets. An angle steel 16 is welded to the inner wall of the upper end of the cylinder 5. A plate-shaped baffle distributor 13 is fixed on the angle steel 16. The angle steel 16 effectively strengthens the support to cope with the impact of large flow and high pressure materials on the plate-shaped baffle distributor 13. It is an important guarantee for the safe use of the plate-shaped baffle distributor 13 to uniformly disperse gas and liquid materials.

[0017] like Figure 2-4As shown, the plate-shaped baffle distributor 13 has a three-way pipe structure, with three pipes evenly distributed at 120° intervals along the circumference. Two pipes are used as the feed section, and the remaining one is used as the mating section. The plate-shaped baffle distributor 13 is assembled from an upper baffle 20, a lower baffle 21, and side baffles 27. Side baffles 27 are only provided on both sides of the feed section port, and a sealing plate 22 is provided at the end port of the mating section to complete the structural support. The two feed section ports have a first gas-liquid inlet 15 and a second gas-liquid inlet 23, which are connected to the feed port of the cylinder 5. A separate connecting plate 25 is provided at the adjacent side of the mating section and the two feed sections. An additional curved guide plate 26 is provided inside the adjacent side of the feed section, and the guide plate 26 protrudes towards the connection center. The remaining sides are through grooves, and several square baffles 24 are evenly spaced in the through grooves. The baffles on both sides of the same pipe are symmetrically arranged. The square baffle 24 is offset outward at an angle of 80° near the connection center. Half of the width of the square baffle 24 is welded to the upper and lower baffles 21 of the sheet baffle distributor 13. The square baffle 24 can change the direction of airflow, making the airflow distribution more uniform, and can also make the liquid distribution uniform. The two sides of the pipe in the feed section converge regularly and smoothly from the port to the connection center, and the two sides of the pipe in the mating section converge regularly and smoothly from the connection center to the port. This design can ensure that the gas and liquid materials flow out from the gaps of the square baffle 24. The inclination of the lower baffle 21 at the feed section is 5°, and the inclination of the lower baffle 21 in the mating section is 6°.

[0018] The gaseous and liquid materials enter the cylinder 5 from two inlets from different directions, flowing through the plate-shaped baffle distributor 13. Simultaneously, the nitrogen inlet 4 and the condensate inlet 18 are opened. The gaseous and liquid materials are transported along the two inlet sections of the plate-shaped baffle distributor 13 towards the connecting center, and then flow from the connecting center towards the port of the mating section. Throughout the process, the gaseous and liquid materials are discharged from the side through-slot under the action of the square baffle 24, completing gas-liquid separation under gravity. The gas rises and exits from the gas outlet 10, transporting to the next process. The liquid flows down from the through-slot of the plate-shaped baffle distributor 13, forming a mist-like electrolyte. This mist-like electrolyte comes into contact with the condensate flowing in from the condensate inlet 18, cooling down and becoming a liquid electrolyte, which is then discharged from the electrolyte outlet 19. If the hydrogen at the gas outlet 10 fails to reach the set accuracy, the electrolyte outlet 19 is connected to a circulation pipeline, and the discharged electrolyte flows back in from the gas-liquid inlet for re-separation, thus obtaining a qualified hydrogen product.

[0019] Increasing the gas-liquid inlet expands the flow rate, shortens the gas-liquid separation time, and increases production capacity. The unique square baffle design accelerates the liquid flow rate, further improving gas-liquid separation efficiency and increasing hydrogen desorption rate, ultimately enhancing the purity of the obtained hydrogen and the utilization rate of the electrolyte. The electrolyte is reused twice within a single unit, eliminating intermediate storage and transfer equipment, thus reducing costs and increasing efficiency. The equipment is suitable for diverse factory production scenarios. Cleaning is convenient; no disassembly is required, and simple washing and purging allows for reuse, saving significant time on equipment cleaning.

[0020] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
