Description

Technical Field

[0001] The utility model relates to the technical field of steam-water separation, in particular to a steam pipeline steam-water separation structure. Background Art

[0002] A steam-water separator is a key device used to effectively separate condensed water and other liquids from steam to ensure the dryness of steam and the efficient operation of the system.

[0003] In the existing steam-water separator, a series of baffles or baffle plates are usually arranged inside it to force the steam to change its flow direction multiple times. When the steam contacts the surface of the baffle or baffle plate, the water vapor in the steam will adhere to the surface of the baffle or baffle plate to form water droplets. Since the water droplets are heavier than the steam, the water droplets are difficult to follow the steam flow due to large inertia when changing direction, so they will separate from the steam, and finally the water droplets can slide down along the wall surface. However, the baffles or baffle plates inside the steam-water separator will gradually heat up with the increase of service time, resulting in difficulty in separating all the water vapor from the steam subsequently, and the achieved steam-water separation effect is poor. Summary of the Utility Model

[0004] In view of this, the utility model provides a steam pipeline steam-water separation structure, which can overcome the disadvantage that the baffles or baffle plates inside the existing steam-water separator will gradually heat up with the increase of service time, resulting in a poor steam-water separation effect.

[0005] A steam pipeline steam-water separation structure includes a cylinder body, an electric control valve I, an electric control valve II, an electric control valve III, a water filling tank, a hollow frame and a water circulation component. The electric control valve I is installed on the side of the cylinder body, the electric control valve II and the electric control valve III are respectively installed at both ends of the cylinder body, the water filling tank is connected to the side of the cylinder body, the hollow frame is connected to the inside of the cylinder body, and the water circulation component is used to control the flow of cold water between the inside of the water filling tank and the inside of the hollow frame.

[0006] Optionally, the water circulation component includes a water pump, a water delivery pipe and a return pipe. The water pump is installed on the inner wall of the water filling tank, the water delivery pipe communicates with the upper end of the hollow frame and the water outlet of the water pump, and the return pipe communicates with the lower end of the hollow frame and the bottom surface of the water filling tank.

[0007] Optionally, it further includes a heat sink, and the heat sink is installed on the side of the water filling tank.

[0008] Optionally, it further includes a baffle, and the baffle is connected to the inner wall of the cylinder body.

[0009] Optionally, it further includes a heat insulation layer, and the heat insulation layer is installed on the outer wall of the cylinder body.

[0010] Optionally, it further includes a mounting ring, a controller and a liquid level sensor. The mounting ring is connected to the cylinder body, the controller is installed on the top surface of the mounting ring, and the liquid level sensor is installed on the cylinder body.

[0011] The beneficial effects of the present utility model are as follows: Through the water pump, the cold water in the water storage tank can be conveyed into the hollow frame, so that the cold water can flow downward in a spiral shape along the inside of the hollow frame, while the steam can float upward in a spiral shape along the outer wall of the hollow frame. The cold water can comprehensively absorb the heat in the water vapor, causing the water vapor to quickly condense into water and drip downward. Description of the Drawings

Specific Embodiments

[0016] The present utility model will be further described below in conjunction with specific embodiments. The illustrative embodiments and explanations of the present utility model are used to explain the present utility model, but do not limit the present utility model.

[0017] Embodiment: A steam pipeline steam-water separation structure, as Figures 1-3 shown, includes a cylinder body 1, an electric control valve I 2, an electric control valve II 3, an electric control valve III 4, a water storage tank 5, a hollow frame 6 and a water circulation component. The electric control valve I 2 is installed in the middle of the right side of the cylinder body 1, the electric control valve II 3 is installed at the lower end of the cylinder body 1, the electric control valve III 4 is installed at the upper end of the cylinder body 1, the water storage tank 5 is connected to the upper left part of the cylinder body 1, the hollow frame 6 is connected to the upper inner part of the cylinder body 1, and the hollow frame 6 is spiral-shaped to increase the contact area between the steam and the outer surface of the hollow frame 6 and can increase the contact time between the steam and the outer surface of the hollow frame 6. The water circulation component is used to control the flow of cold water between the inside of the water storage tank 5 and the inside of the hollow frame 6.

[0018] The water circulation component includes a water pump 7, a water delivery pipe 8 and a return pipe 9. The water pump 7 is installed at the upper part of the inner wall of the water storage tank 5, and the water inlet of the water pump 7 is communicated with the inside of the water storage tank 5. The water delivery pipe 8 is connected to the upper left part of the cylinder body 1, and both ends of the water delivery pipe 8 are respectively communicated with the upper end of the hollow frame 6 and the water outlet of the water pump 7. The return pipe 9 is connected to the middle left part of the cylinder body 1, and both ends of the return pipe 9 are respectively communicated with the lower end of the hollow frame 6 and the bottom surface of the water storage tank 5.

[0019] It also includes a heat sink 501, a baffle 10, a heat insulation layer 11, an installation ring 12, a controller 13 and a liquid level sensor 14. The heat sink 501 is installed on the left side of the water storage tank 5. The baffle 10 is connected to the middle part on the right side of the inner wall of the cylinder body 1. The baffle 10 is located below the hollow frame 6 and directly to the left of the electric control valve I 2. The heat insulation layer 11 is installed on the outer wall of the cylinder body 1. The installation ring 12 is connected to the lower part of the outer wall of the cylinder body 1. The controller 13 is installed on the front side of the top surface of the installation ring 12. The liquid level sensor 14 is installed on the lower part of the front side of the cylinder body 1.

[0020] First, install this structure at the designated position, and then control the opening of the electric control valve I 2 and the electric control valve III 4 through the controller 13, so that steam can enter the inside of the cylinder body 1 through the electric control valve I 2. At this time, the steam will first contact the right side of the baffle 10. The baffle 10 can change the flow direction of the steam, making the steam bypass the baffle 10. At this time, some water vapor in the steam will adhere to the surface of the baffle 10 and condense into water and drip downwards. At the same time, the steam bypassing the baffle 10 will float upwards in the cylinder body 1 to contact the hollow frame 6, making the steam float upwards along the outer wall of the hollow frame 6 in a spiral route. The water vapor in the steam will adhere to the outer wall of the hollow frame 6. At this time, the water in the water storage tank 5 can be pumped by the water pump 7, and the cold water can be transported into the hollow frame 6 through the water delivery pipe 8, so that the cold water can flow downwards along the inside of the hollow frame 6 in a spiral route. The cold water can absorb the heat of the water vapor on the outer wall of the hollow frame 6, making the water vapor quickly condense into water and drip downwards along the outer wall of the hollow frame 6. The water that absorbs heat in the hollow frame 6 will return to the water storage tank 5 through the return pipe 9 and mix with other cold water. The heat sink 501 can absorb the heat in the water and discharge it outwards. In this way, by circulating, there will always be cold water flowing downwards in the hollow frame 6, ensuring the steam-water separation effect on the steam. The steam from which the water vapor has been removed can be discharged upwards through the electric control valve III 4. The heat insulation layer 11 can isolate the temperature inside the cylinder body 1 and prevent a large amount of external dust from adhering to the outer wall of the cylinder body 1. The liquid level sensor 14 can monitor the liquid level height at the bottom inside the cylinder body 1 in real time. When the liquid level height detected by the liquid level sensor 14 is higher than the preset value, the liquid level sensor 14 will send a signal. After receiving the signal, the controller 13 can control the opening of the electric control valve II 3, so that the water at the bottom inside the cylinder body 1 can be discharged downwards through the electric control valve II 3. When all the water is discharged, the controller 13 can control the closing of the electric control valve II 3.

[0021] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
