Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steam-water separator, especially to a vacuum steam-water separator. BACKGROUND

[0002] In the production of the paper industry, steam heating, steam power and steam condensation recovery are widely used in the process, which inevitably produces a large amount of mixed gas containing steam and water in the production process. In the key parts of the paper machine net, the existence of steam and water mixture brings many problems. On the one hand, steam will interfere with the drying process of paper, reduce the drying quality, and then affect the quality and production efficiency of paper; on the other hand, too much water will accelerate the corrosion of equipment, cause pipeline blockage, and cause unnecessary waste of energy.

[0003] Therefore, the efficient separation of steam and water is of great significance to ensure the stability of paper industry production, improve energy utilization efficiency and protect subsequent equipment.

[0004] However, the traditional steam-water separator has many shortcomings when dealing with the complex working conditions of the paper industry. When facing high vacuum requirements and high separation precision requirements, the unreasonable structure design is particularly obvious. The internal structure of some traditional steam-water separators is too simple, which cannot provide sufficient separation space, and the separation means used also lacks effectiveness, which is difficult to meet the actual production requirements of efficient separation of steam-water mixture. For example, due to the limited separation space, the steam-water mixture cannot be fully contacted and separated, resulting in unsatisfactory separation effect; at the same time, in the high vacuum environment, these separators are difficult to maintain stable performance, and cannot realize high-precision separation, so that a large amount of water is still entrained in the steam, which not only affects the normal operation of the subsequent equipment, but also reduces the overall production benefit. In addition, the traditional steam-water separator also has defects in space layout adaptability, which is difficult to meet the diversified production environment and equipment layout requirements in the paper industry. The existence of these problems urgently needs a new type of steam-water separator which can effectively increase the separation path and contact area of steam-water mixture, significantly improve the separation efficiency, and is especially suitable for high-precision separation requirements in high-vacuum environment.

[0047] I. Detailed structure and connection mode of each component

[0048] The tank assembly: the tank assembly is composed of the tank inclined side plate 1, the tank top plate 2, the tank inlet port side plate 6 and the tank end plate 11 to form a tank shell structure. The tank inclined side plate 1 and the tank top plate 2 cooperatively form a tank shell side and top structure with an inclined angle, are made of high-quality stainless steel material, have good corrosion resistance and structural strength, and the inclined design is helpful for the natural upward flow of steam in the tank and the collection of condensed water.

[0049] Steam extraction pipe 3: Set on the top of the box assembly, it is connected with the steam space inside the box assembly. Its diameter and length are designed accurately, and the inner wall is smooth to ensure that the separated steam can be discharged smoothly in a vacuum environment, while minimizing the resistance loss of the steam and preventing the attachment and accumulation of tiny droplets in the steam on the pipe wall.

[0050] Two-end partition plate 4: Installed at both ends of the box assembly, it is used to divide the space inside the box assembly longitudinally, and plays a role in preliminary guiding the flow path of the steam-water mixture and preliminary separation. The plate is provided with flow guide grooves or holes to make the steam-water mixture distribute to each separation area according to the predetermined direction and speed.

[0051] Inlet pipe 5: Located at the lower part of one side of the box assembly, it is connected with the external steam-water mixture conveying pipeline and is designed in a gradually expanding manner. This structure can effectively reduce the flow rate of the steam-water mixture when it enters the box, reduce the impact and turbulence, and make the steam-water mixture enter the separation area more smoothly, thereby improving the initial separation effect.

[0052] Box inlet side plate 6: Adjacent to the inlet pipe 5, it is designed to be strengthened to withstand the impact force when the steam-water mixture enters. At the same time, some auxiliary flow guide structures or buffer devices can be provided on the side plate to further optimize the distribution state of the steam-water mixture after entering the box.

[0057] Intermediate partition plate 13: correspondingly arranged in each separation chamber, which can be a perforated plate, a corrugated plate or other special structural forms, used to increase the flow path and contact area of the steam-water mixture, and to promote the separation of steam and condensed water. For example, the perforated plate can cause the steam to produce multiple small turns and collisions when passing through, making it easier for liquid droplets to be separated out.

[0058] II. Working principle

[0059] Introduction of steam-water mixture

[0060] The mixed gas containing a large amount of steam and water enters the vacuum steam-water separator through the inlet pipe 5. The inlet pipe 5 adopts a gradually expanding design, which plays an important role. When the steam-water mixture flows in, the pipe diameter gradually expands, and according to the principle of fluid mechanics, the flow rate will decrease accordingly. This avoids the steam-water mixture from entering the interior of the box at high speed, reducing the generation of impact and turbulence. At the same time, the side plate 6 of the box inlet is adjacent to the inlet pipe 5 and is designed to be reinforced, which can withstand the impact force when the steam-water mixture enters. Auxiliary flow guiding structures or buffer devices that can be provided on the side plate further adjust the flow direction and flow rate of the steam-water mixture, so that it can enter the area preliminarily divided by the two end partition plates 4 more smoothly and uniformly, creating good initial conditions for the subsequent separation process.

[0061] Preliminary separation and flow direction guiding

[0062] The two end partition plates 4 are installed at both ends of the interior of the box assembly, dividing the box longitudinally. These partition plates are provided with flow guide grooves or flow guide holes, and when the steam-water mixture enters the area divided by them, it will flow according to the direction and speed set by the flow guide grooves or flow guide holes. This process realizes the preliminary separation of the steam-water mixture, as the steam and water have different densities, there will be a certain degree of separation tendency during the flow process. At the same time, the flow guiding structure guides the steam-water mixture to enter the subsequent separation chambers in an orderly manner, avoiding the disorderly flow of the fluid in the box, and improving the efficiency and effect of separation.

[0063] Multi-chamber multi-stage separation

[0064] The box partition plate 12 is arranged transversely inside the box assembly, separating it into no less than nine independent separation chambers. Each separation chamber can be regarded as a relatively independent separation unit, with specific separation functions and conditions. When the steam-water mixture flows through these separation chambers in sequence, it will undergo multiple separation processes. The intermediate partition plate 13 further subdivides the space within each separation chamber, increasing the flow path and contact area of the steam-water mixture. For example, if the intermediate partition plate 13 adopts a perforated plate structure, the steam will undergo multiple small turns and collisions when passing through these small holes. According to the principle of inertia, the liquid droplets carried in the steam, due to their larger mass, also have greater inertia, and are more likely to separate from the steam during the turning and collision process, thereby adhering to the surface of the partition plate or falling under the action of gravity. In addition, there may be temperature gradients, airflow speed differences, and other conditions in different separation chambers, all of which contribute to further promoting the separation of steam and water. In this multi-chamber multi-stage separation process, the steam-water mixture is continuously separated, the water content in the steam gradually decreases, and the separation effect continuously improves.

[0065] Steam discharge

[0066] After multi-chamber multi-stage separation, the relatively pure steam rises inside the box and is discharged through the suction pipe 3 arranged at the top of the box. The diameter and length of the suction pipe 3 are precisely designed, and the inner wall is smooth to ensure that the steam can be smoothly discharged in a vacuum environment. At the same time, the outlet reducer 8 and the outlet pipe 9 further optimize the discharge of steam. The outlet reducer 8 gradually transitions the larger steam outlet channel inside the box to the smaller outlet pipe 9, which can improve the discharge speed and pressure of the steam, making the separated steam more efficiently transported to subsequent equipment or process links, reducing energy loss and liquid droplet entrainment during the discharge process, and ensuring the quality and transportation efficiency of the steam.

[0067] Condensate discharge

[0068] During the separation process of the steam-water mixture, water collects at the bottom of the box under the action of gravity along the box inclined side plate 1 and the box end plate 11. The box end plate 11 is provided with a drainage channel or drainage interface, and the separated condensate is discharged from the box through these channels or interfaces, avoiding the accumulation of water in the box and affecting the separation effect.

[0069] Operation monitoring and sterile assurance

[0070] During the whole working process, the operator can observe the steam-water separation condition in the box in real time through the flange sight mirror hand hole 7 installed on the inclined side plate 1 of the box. For example, the liquid level height can be observed to know the accumulation condition of the condensed water, the steam flow state can be observed to judge whether the separation is normally carried out, and whether there is a blockage or abnormal phenomenon is found in time, so as to adjust and maintain in time. When it is necessary to be connected with the sterile environment related equipment, the sterile flange 10 on the steam extraction pipe 3 adopts a special sealing structure and material, which can effectively prevent external microorganisms from entering the box, so that the steam-water separation process is carried out under sterile conditions, and the application requirements of the food, pharmaceutical and other industries with high hygiene requirements are met.

[0071] Through the cooperation of the above components, the vacuum steam-water separator effectively increases the steam-water mixture separation path and contact area, significantly improves the separation efficiency, adapts to high vacuum environment and complex working conditions, and has good practicability and application value.

[0072] It should be understood by those skilled in the art that the above description and the embodiments of the utility model shown in the drawings are only as examples and do not limit the utility model. The purpose of the utility model has been completely and effectively realized. The function and structural principle of the utility model have been displayed and explained in the embodiments, and the embodiments of the utility model can be deformed or modified without departing from the principle.
