Description

Technical Field

[0001] This utility model relates to the field of acrylic acid production technology, and in particular to a dehydration tank with a simple automatic drainage function. Background Technology

[0002] A dehydration tank is a device that removes water using physical or chemical methods. By installing a drain regulating valve on its drain line, the liquid level is controlled during the drainage process to achieve drainage.

[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] Adding additional drainage regulating valve equipment to the drainage pipeline increases costs. As a mechanical device, the drainage regulating valve requires regular maintenance, which increases subsequent maintenance costs. If the performance of the drainage regulating valve is unstable, it will lead to a decrease in drainage efficiency, which will not be able to meet the drainage needs of the dehydration tank, and may even lead to safety hazards.

[0005] For example, application number CN201922017931.3 discloses an automatic drainage device for a hydrogen dehydration tank.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a dehydration tank with a simple automatic drainage function, to solve the technical problems of existing dehydration tanks with defects in drainage design. These existing tanks require additional drainage regulating valves on the drainage pipeline, increasing costs and requiring regular maintenance. Furthermore, unstable performance of the drainage regulating valve can lead to decreased drainage efficiency, failing to meet the drainage needs of the dehydration tank, and even causing safety hazards. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This utility model provides a dehydration tank with a simple automatic drainage function, including a tank body, a wire mesh demister and a liquid seal pipe. The wire mesh demister is installed on the airflow channel of the air inlet and air outlet of the tank body, and the liquid seal pipe is installed on the drainage pipeline of the tank body.

[0010] Preferably, the liquid seal pipe has an inverted U-shaped structure, and the liquid seal horizontal section of the liquid seal pipe is higher than the drainage horizontal section of the drainage pipeline, and the drainage horizontal section is higher than the ground.

[0011] Preferably, the vertical distance between the drainage horizontal section and the ground is 1m, and the vertical distance between the liquid seal horizontal section and the drainage horizontal section is 1.5m.

[0012] Preferably, a lens is provided at the outlet end of the liquid seal tube.

[0013] Preferably, the bottom of the tank has an inverted conical structure, and the vertical drainage section of the drainage pipeline is connected to the bottom of the tank.

[0015] Preferably, the wire mesh demister includes a first demister section and a second demister section arranged concentrically from top to bottom. The first demister section is a circular plate structure and abuts against the inner wall of the tank. The second demister section is a hollow column structure and is arranged corresponding to the air inlet.

[0016] Preferably, the tank is equipped with a level gauge.

[0017] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0018] This invention effectively avoids the defects in the drainage design of existing dehydration tanks, which require additional drainage regulating valves on the drainage pipeline, increasing costs and necessitating regular maintenance. Unstable performance of the drainage regulating valve can lead to decreased drainage efficiency, failing to meet the drainage needs of the dehydration tank and even causing safety hazards. This invention provides a dehydration tank with a simple automatic drainage function, including a tank body, a wire mesh demister, and a liquid seal pipe. The wire mesh demister is installed in the airflow channels of the tank body's inlet and outlet, and the liquid seal pipe is installed on the drainage pipeline of the tank body. The wire mesh demister, installed in the airflow channels of the tank body's inlet and outlet, is used to remove moisture from the gas, improving dehydration efficiency. As the dehydration process proceeds, the removed moisture gradually accumulates at the bottom of the tank. When the pressure of the accumulated water in the tank exceeds the liquid seal pressure of the liquid seal pipe, the accumulated water flows naturally into the liquid seal pipe under pressure, forming a liquid column within the liquid seal pipe. As the amount of water continues to increase, the height of the liquid column gradually rises until it exceeds the highest point of the liquid seal pipe, thereby driving the water to drain smoothly and achieving continuous and efficient automatic drainage without human intervention.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figure 1 As shown, this utility model provides a dehydration tank with a simple automatic drainage function, including a tank body 1, a wire mesh demister 2 and a liquid seal pipe 3. The wire mesh demister 2 is installed on the airflow channel of the air inlet 12 and the air outlet 13 of the tank body 1, and the liquid seal pipe 3 is installed on the drainage pipeline 11 of the tank body 1.

[0030] The wire mesh demister 2 is installed on the airflow channel between the air inlet 12 and the air outlet 13 of the tank body 1 to remove moisture from the gas and improve the dehydration efficiency.

[0031] As the dehydration process proceeds, the removed water gradually accumulates at the bottom of tank 1.

[0032] When the pressure of the water inside tank 1 exceeds the liquid seal pressure of liquid seal pipe 3, the water flows naturally into liquid seal pipe 3 under pressure and forms a liquid column inside liquid seal pipe 3. As the amount of water continues to increase, the height of the liquid column gradually rises until it exceeds the highest point of liquid seal pipe 3, thereby driving the water to be discharged smoothly, achieving continuous and efficient automatic drainage without manual intervention.

[0033] This invention achieves automatic drainage by setting a liquid seal pipe 3, eliminating the need for an additional drainage regulating valve, simplifying the structure, reducing costs, and improving drainage efficiency and stability.

[0034] As an optional implementation, the liquid seal pipe 3 has an inverted U-shaped structure, and the liquid seal horizontal section 32 of the liquid seal pipe 3 is higher than the drainage horizontal section 112 of the drainage pipeline 11, and the drainage horizontal section 112 is higher than the ground 5.

[0035] Furthermore, the drainage pipeline 11 is connected to the main collection pipe 4 via the liquid seal pipe 3, so that the water discharged from the dehydration tank can smoothly enter the main collection pipe 4 for unified collection and subsequent treatment.

[0036] The liquid seal pipe 3 includes a first liquid seal vertical section 31, a liquid seal horizontal section 32, and a second liquid seal vertical section 33 connected in sequence. The first liquid seal vertical section 31 is connected to the drainage horizontal section 112 of the drainage pipeline 11, the drainage vertical section 111 of the drainage pipeline 11 is connected to the tank body 1, and the second liquid seal vertical section 33 is connected to the liquid collection main pipe 4.

[0037] When the water pressure inside tank 1 reaches or exceeds the liquid seal pressure, the water will flow along the vertical drainage section 111 into the horizontal drainage section 112, and then into the liquid seal pipe 3, forming a liquid column in the first vertical liquid seal section 31. As the water accumulates in the liquid seal pipe 3, when the height of the liquid column exceeds the horizontal liquid seal section 32, the water will flow into the main collection pipe 4 through the second vertical liquid seal section 33 under the combined action of gravity and pressure.

[0038] As an optional implementation, the vertical distance between the drainage horizontal section 112 and the ground 5 is 1m. The vertical distance between the liquid seal horizontal section 32 and the drainage horizontal section 112 is 1.5m, forming an effective liquid seal.

[0039] When the liquid seal height is 1.5 meters, the pressure that can be sealed is (1.5 / 10)*100kpag=15kpag. That is, when the pressure inside the tank 1 reaches or exceeds 15kpag, the accumulated water will flow into the drainage horizontal section 112 along the vertical drainage section 111 under the action of pressure, and further enter the liquid seal pipe 3.

[0040] The liquid seal height is the vertical distance between the horizontal liquid seal section 32 and the horizontal drainage section 112. The pressure that the liquid seal height can seal corresponds to the highest operating pressure inside tank 1. It should be noted that the liquid seal height can be adjusted according to the actual operating pressure of tank 1. If the operating pressure of tank 1 is high, the liquid seal height can be increased appropriately; conversely, the liquid seal height can be decreased appropriately to simplify the structure.

[0041] As an optional implementation, a lens 6 is provided at the outlet end of the liquid seal tube 3.

[0042] Furthermore, the second vertical section 33 of the liquid seal is equipped with a lens 6, which allows for a clear and intuitive view of the water flow in the liquid seal pipe 3.

[0043] As an optional implementation, the bottom of the tank 1 has an inverted conical structure, and the vertical drainage section 111 of the drainage pipeline 11 is connected to the bottom of the tank 1.

[0044] The inverted cone-shaped structure gradually reduces the space at the bottom of the tank 1, making it easier for water to collect and drain.

[0045] As an optional implementation, the air inlet 12 is provided on the side wall of the tank body 1, and the air outlet 13 of the tank body 1 is provided on the top of the tank body 1.

[0046] As an optional implementation, the wire mesh demister 2 includes a first demister 21 and a second demister 22 arranged concentrically from top to bottom. The first demister 21 is a circular plate structure and abuts against the inner wall of the tank 1; the second demister 22 is a hollow column structure and is arranged corresponding to the air inlet 12.

[0047] Furthermore, the second demisting unit 22 is positioned directly opposite the air inlet 12, and can directly intercept the gas entering the tank 1 through the air inlet 12.

[0048] Gas enters the tank 1 through the inlet 12, first impacting the second demister 22. There, gas condenses and gathers into larger droplets, which then detach from the second demister 22 under gravity and fall to the bottom of the tank 1, achieving efficient moisture removal. As the airflow rises, it comes into contact with the first demister 21. The large-area plate-like structure of the first demister 21 further increases the contact area between the gas and the first demister 21, effectively removing residual moisture from the gas during the impact process.

[0049] The effective removal of moisture from the gas is achieved through the synergistic effect of the first demister 21 and the second demister 22.

[0050] As an optional implementation, a level gauge 14 is provided on the tank 1 for real-time monitoring and control of the water level inside the tank 1.
