[0002] Water seal tanks are a commonly used method of shut-off, with advantages such as ease of manufacture, low cost, good sealing, and no leakage.

[0003] In gaseous media, such as flue gas containing polar gases like SO2, SO3, NOx, and HCl, the presence of oxygen and water in the presence of polar gases easily generates a mixture of various acidic substances, including H2SO3, H2SO4, HNO2, HNO3, and HCl. As the acidic components in the flue gas dissolve into the water and gradually accumulate, the acidity of the water gradually increases and the pH gradually decreases, thus corroding the inner sleeve and causing the water seal to fail.

[0004] In conclusion, how to reduce the acidity of the water inside the water seal tank is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a water seal tank that continuously releases alkaline substances through a neutralizing agent, effectively preventing the metal parts such as the inner tank that come into contact with water from being corroded by acid, and extending the service life of the water seal device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A water-sealed tank, comprising: The tank body is provided with an air inlet coaxial with it and an exhaust outlet perpendicular to it, and an air inlet pipe communicating with the air inlet is provided inside the tank body; A storage tank, wherein the storage tank has a filling cavity that communicates with the tank body, and the filling cavity is filled with a neutralizing agent.

[0008] Furthermore, the pressure plate includes a first guide plate, a second guide plate, and a third guide plate arranged sequentially. The cross-sections of the first guide plate and the third guide plate are both arc-shaped structures with openings facing each other. The second guide plate is smoothly connected to the first guide plate and the third guide plate.

[0009] Furthermore, the pressure plate is detachably connected to the storage tank, and the storage tank is fixed to the bottom of the tank body.

[0010] Furthermore, in this invention, the storage tank is slidably installed inside the tank body along the axis of the tank body, a partition is provided inside the storage tank, a filling cavity is formed between the partition and the pressure plate, and a closed buoyancy cavity is formed between the partition and the bottom of the storage tank.

[0011] Furthermore, the present invention provides a guide post arranged parallel to its axis inside the tank, and the storage tank and the guide post are in sliding fit.

[0012] Furthermore, in this invention, the neutralizing agent is an alkaline compound.

[0013] Furthermore, the tank body is provided with a water inlet and a water outlet, and the tank body also includes a cleaning port, on which a closing door is installed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The core of this invention is to provide a water seal tank in which an alkaline substance is continuously released through a neutralizing agent, effectively preventing the metal parts, such as the inner tank, that come into contact with water from being corroded by acid, and extending the service life of the water seal device.

[0022] Please refer to Figure 1 A water seal tank includes a tank body 1 and a storage tank 5. The tank body 1 is provided with an air inlet 2 coaxial with it and an exhaust port 3 perpendicular to it. The tank body 1 is provided with an air inlet pipe 4 communicating with the air inlet 2. The storage tank 5 is provided with a filling cavity communicating with the outside. The filling cavity is filled with a neutralizing agent 6.

[0023] It should be noted that in this embodiment of the utility model, the tank 1, the air inlet pipe 4, and the storage tank 5 are all made of metal.

[0024] Furthermore, its surface in contact with water can be uniformly coated with a corrosion-resistant coating.

[0025] In addition, in this embodiment of the present invention, the exhaust port 3 can be located on the side wall of the tank body 1, and the height of the exhaust port 3 is higher than the water surface of the water seal tank during water sealing.

[0026] In addition, in this embodiment of the invention, the water required for the water seal can be replenished or discharged through the inlet 11 or the outlet 12, or an inlet and outlet can be provided at the bottom of the tank 1 to facilitate the establishment or release of the water seal.

[0027] Optionally, in some embodiments, the air inlet 2 may be arranged not on the same axis as the tank body 1, as long as the air inlet 2 is connected to the air inlet pipe 4, and the bottom of the air inlet pipe 4 is placed below the water surface when the water seal tank is in water seal mode.

[0028] Optionally, in some embodiments, the diameter of the air inlet pipe 4 is smaller than the diameter of the tank body 1, and the diameter of the storage tank 5 is smaller than the diameter of the tank body 1 but larger than the diameter of the air inlet pipe 4.

[0029] Optionally, in some embodiments, the storage tank 5 may have a structure with several water inlets, that is, after the neutralizing agent 6 is placed inside the storage tank 5, water enters the storage tank 5 through the water inlets, thereby causing the neutralizing agent 6 to release alkaline substances.

[0030] In use, the storage tank 5 is installed inside the tank body 1. The tank body 1 has an air inlet 2 coaxial with it and an exhaust port 3 perpendicular to it. The tank body 1 has an air inlet pipe 4 connected to the air inlet 2. That is, when the water seal is applied, the tank body 1 is filled with water so that the bottom of the air inlet pipe 4 is below the water surface, and the storage tank 5 is below the water surface. Under the action of the pressure difference between the flue gas inlet and outlet, the water level is balanced with it, thus forming a water seal. The acidic components contained in the flue gas enter the water and react with the neutralizing agent 6 in the neutralization storage tank, so that the neutralizing agent 6 continuously releases alkaline substances, ensuring that the pH value of the water is within a reasonable range. This effectively avoids corrosion of the metal parts in contact with water, such as the inner tank body 1, and helps to improve the service life and sealing effect of the water seal device.

[0031] Please refer to Figure 3 In some embodiments, the top of the storage tank 5 is provided with an opening, and a pressure plate 7 is provided at the opening of the storage tank 5 so that a filling cavity is formed below the pressure plate 7. The pressure plate 7 is provided with a plurality of water passage holes. That is to say, the storage tank 5 blocks the neutralizing agent 6 by the pressure plate 7 to prevent the neutralizing agent 6 from floating in the tank 1, and the water passage holes provided on the pressure plate 7 allow water to fully contact the neutralizing agent 6.

[0032] Optionally, in some embodiments, the total volume of the neutralizing agent 6 is smaller than the volume of the filling cavity, preferably 80% of the volume of the filling cavity, in order to improve the fluidity of the neutralizing agent 6 in the filling cavity. Under the impact of the flue gas passing through the air inlet pipe 4, the neutralizing agent 6 can move fully in the filling cavity, so as to achieve the purpose of the neutralizing agent 6 being in full contact with water.

[0033] Optionally, in some embodiments, a mixing device may be installed in the storage tank 5. Specifically, the mixing device includes a rotating shaft, a motor, and blades mounted on the rotating shaft, which agitate the neutralizer 6 to move sufficiently within the filling cavity.

[0034] Please refer to Figure 3 In some embodiments, the pressure plate 7 includes a first guide plate 703, a second guide plate 702, and a third guide plate 701 arranged sequentially. The cross-sections of the first guide plate 703 and the third guide plate 701 are both arc-shaped structures with openings facing each other. The second guide plate 702 is smoothly connected to the first guide plate 703 and the third guide plate 701. That is, the pressure plate 7 is divided into multiple segments. The cross-sections of the first guide plate 703 and the third guide plate 701 are arc-shaped structures with openings facing each other, which enables them to guide the water flow and flue gas. When the flue gas enters the water and flows downward, it is diverted by the third guide plate 701 and then guided upward by the first guide plate 703, thereby achieving rapid discharge of the flue gas. Furthermore, the arc-shaped structure of the guide plate is in the normal flow state after the water seal is released, and its guiding effect achieves a low pressure drop in the water seal tank.

[0035] Optionally, in some embodiments, the pressure plate 7 formed by the first guide plate 703, the second guide plate 702 and the third guide plate 701 has a W-shaped cross-section, and the center of the pressure plate 7 is located on the axis of the air inlet pipe 4, so that it can guide and optimize the flue gas flow field, thereby achieving a low pressure drop in the water seal tank.

[0036] Optionally, in some embodiments, the second guide plate 702 is provided with a plurality of slag discharge ports, and a cover plate is rotatably installed at the slag discharge ports, the other end of the cover plate being closable and installed on the second guide plate 702.

[0037] In other embodiments, the first guide plate 703, the second guide plate 702 and the third guide plate 701 are welded together to form a whole, and the pressure plate 7 is connected to the storage tank 5 by bolts or other means, so the neutralizer 6 can be replaced in a detachable manner.

[0038] Please refer to Figure 3 In some embodiments, the pressure plate 7 is detachably connected to the storage tank 5, and the storage tank 5 is fixed to the bottom of the tank body 1. That is, in this embodiment, the storage tank 5 is fixed to the bottom of the tank body 1 and does not move.

[0039] Optionally, in some embodiments, the storage tank 5 is slidably installed inside the tank body 1 along the axis of the tank body 1. The storage tank 5 is provided with a baffle 8, and a filling cavity is formed between the baffle 8 and the pressure plate 7. That is, in this embodiment, the storage tank 5 slides inside the tank body 1. When the water seal is established, the storage tank 5 rises with the water level and eventually contacts the air inlet pipe 4, thereby enabling the flue gas to quickly and directly contact the neutralizing agent 6 and increase the neutralization efficiency.

[0040] Optionally, in some embodiments, a buoyancy cavity 9 is formed between the partition 8 and the bottom of the storage tank 5. That is, the buoyancy cavity 9 is separated by the partition 8 and the storage tank 5. Under the action of the buoyancy cavity 9, the storage tank 5 has buoyancy. Therefore, when a water seal is established, the storage tank 5 rises with the water level under its own buoyancy and eventually contacts the air inlet pipe 4. This enables the flue gas to come into rapid and direct contact with the neutralizing agent 6. It adopts a mechanical structure, which helps to reduce the manufacturing cost of the device.

[0041] In other embodiments, a screw with its axis parallel to the axis of the tank body 1 is rotatably installed inside the tank body 1, and the screw is rotated by a motor. The storage tank 5 is threadedly engaged with the screw, so the height of the storage tank 5 is controlled by the motor to achieve different heights required for different flue gas intakes.

[0042] Please refer to Figure 1 In some embodiments, the tank body 1 is provided with a guide post 10 arranged parallel to its axis, and the storage tank 5 is slidably engaged with the guide post 10. That is, by setting the guide post 10, the movement path of the storage tank 5 is controlled, making it more stable when rising and falling.

[0043] Optionally, in some embodiments, the guide post 10 may be provided in multiples or as a single one. When multiple guide posts are provided, they are evenly distributed along the axis of the tank body 1. When a single guide post is provided, the guide post 10 is arranged coaxially with the tank body 1, while the storage tank 5 is arranged coaxially with the tank body 1.

[0044] In the above embodiment, the storage tank 5 adopts an annular structure to form a through hole in the middle. At the same time, the buoyancy cavity 9 of the storage tank 5 has a sealing effect, so the guide post 10 passes through the through hole to guide its movement direction.

[0045] Optionally, in some embodiments, the neutralizing agent 6 is an alkaline compound.

[0046] Optionally, in some embodiments, the neutralizing agent 6 is an alkali metal oxide (including zinc and sodium) or mixture thereof, such as MgO, Mg(OH)2, CaO, Ca(OH)2, CaCO3, or MgCO3, and one or more of these are used in combination. These components react with water to form an alkaline solution, which can neutralize acidic substances in the water, increase the pH value, and adsorb or remove Cl from the water. - .

[0047] Optionally, in some embodiments, the neutralizing agent 6 is in the shape of a sheet or a sphere, with a layered micro-nest structure, which increases the surface area to control the release rate of the effective component, ensuring the stable release of the effective component over a long period of time and having a long-lasting sustained-release function.

[0048] Please refer to Figure 1 In some embodiments, the tank 1 is provided with a water inlet 11 and a drain outlet 12, and valves are installed at both the water inlet and the drain outlet 12. Both the water inlet 11 and the drain outlet 12 are located at the bottom of the tank 1.

[0049] Please refer to Figure 1 In some embodiments, the tank 1 also includes a cleaning port 13, which is equipped with a closing door to facilitate the cleaning and discharge of the neutralizing agent 6 after use.

[0050] Please refer to Figure 1 In some embodiments, the tank 1 is provided with an addition tube 14 connected thereto, which is used to add the neutralizing agent 6.

[0051] Please refer to Figure 1 In some embodiments, the tank 1 is provided with an overflow pipe 15 connected to it, and a pH meter 16 is installed on the overflow pipe 15. The pH value of the water in the tank 1 is measured in a timely manner by the pH meter 16 to ensure that the acidity of the water is known in a timely manner.

[0052] In the above embodiment, when the storage tank 5 is fixed, the cleaning port 13 and the adding pipe 14 are directly connected to the filling cavity of the storage tank 5, and solenoid valves are installed at the connection between them and the tank body 1. A filter device and a pump are installed at the cleaning port 13. The pump is installed at the end of the filter device away from the tank body 1. The used neutralizing agent 6 is sucked out by the pump and filtered out by the filter device. An air pump is installed on the adding pipe 14. The air pump blows the new neutralizing agent 6 into the filling cavity. Therefore, the air pump, water pump, pH meter 16 and solenoid valve are all electrically connected to the control system. When the pH meter 16 detects that the pH value of the water has decreased, it automatically controls the air pump and water pump to work, so as to realize the automatic replacement of the neutralizing agent 6.

[0053] In other words, the key point of this utility model is that the storage tank 5 is installed inside the tank body 1. The tank body 1 is provided with an air inlet 2 coaxial with it and an exhaust port 3 perpendicular to it. The tank body 1 is provided with an air inlet pipe 4 connected to the air inlet 2. That is to say, when the water seal is performed, the tank body 1 is filled with water so that the bottom of the air inlet pipe 4 is below the water surface, and the storage tank 5 is located below the water surface. Under the action of the pressure difference between the flue gas inlet and outlet, the water level is balanced with it, thus forming a water seal. The acidic components contained in the flue gas enter the water and react with the neutralizing agent 6 in the neutralization storage tank, so that the neutralizing agent 6 continuously releases alkaline substances, ensuring that the pH value of the water is within a reasonable range. This effectively avoids corrosion of the metal parts such as the inner tank body 1 that come into contact with water, which is beneficial to improving the service life and sealing effect of the water seal device.
