Description

Technical Field

[0001] This utility model relates to the field of water seal tank technology, and in particular to a liquid level control structure for a water seal tank. Background Technology

[0002] Water seal tanks are a common safety isolation device in wastewater treatment processes. They play an effective role in isolating and protecting the biogas utilization system from the pipeline. Conventional water seal tanks require pressure regulation, which necessitates monitoring the liquid level inside the tank. The higher the liquid level, the higher the pressure, and the tank is then vented or replenished based on the pressure value. However, the pressure inside the water seal tank fluctuates with the release or replenishment of biogas, causing the liquid level to fluctuate as well, making it difficult to monitor the liquid level.

[0003] Therefore, there is an urgent need to design a water seal tank level control structure to overcome the shortcomings of one or more of the existing technologies. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a water seal tank liquid level control structure, characterized in that it includes: a tank body, the tank body is divided into a liquid area and a gas area by a gas baffle plate, the bottom of the gas area is connected to the bottom of the liquid area, the gas area is provided with an air inlet and an air outlet, the liquid area is provided with a water outlet, and the liquid area is also provided with a liquid level sensor.

[0005] In a preferred embodiment, a plurality of water distribution perforated plates are also provided at intervals at the bottom of the liquid zone.

[0006] In a preferred embodiment, an auxiliary vent is also provided at the top of the liquid zone.

[0007] In a preferred embodiment, the outlet is connected to a drainage pipe, which is narrowed at a predetermined position.

[0008] The beneficial effects of this utility model are: by dividing the tank body into two zones, the liquid can flow between the two zones, but the gas can be blocked in the gas zone, ensuring the stability of the liquid level and the accuracy of monitoring. In addition, several water equalization plates are provided in the liquid zone. The water equalization plates reduce the liquid level fluctuation caused when the liquid enters the tank. At the same time, automatic control, automatic water replenishment and drainage can be achieved through liquid level monitoring. Attached Figure Description

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0014] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0015] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0016] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1 As shown, a water seal tank level control structure is provided, characterized in that it includes: a tank body 10, the tank body 10 is divided into a liquid zone 11 and a gas zone 12 by a gas baffle 13, the gas zone 12 is connected to the bottom of the liquid zone 11, the gas zone 12 is provided with an air inlet 15 and an air outlet 16, the liquid zone 11 is provided with a water outlet 18, and the liquid zone 11 is also provided with a liquid level sensor.

[0018] Specifically, the bottom of the baffle plate 13 is 5cm away from the bottom wall of the tank 10. The tank 10 is divided into a liquid zone 11 and a gas zone 12 by the baffle plate 13. The liquid zone 11 contains liquid, and the gas zone 12 contains both gas and liquid. The bottoms of the liquid zone 11 and the gas zone 12 are connected. External liquid and gas enter through the air inlet 15, which is equipped with a pipe. The pipe's port inside the tank is 15cm away from the bottom wall of the tank. The entering liquid enters the liquid zone 11 from the gas zone 12 through the bottom connection, while the gas is separated by the baffle plate 13. The barrier between the gas plate 13 and the liquid leaves gas in the gas zone 12, causing gas-liquid separation. Traditional water seal tanks do not have this barrier, so the intake and exhaust of gas would cause large fluctuations in the liquid level, making it difficult to detect. However, when gas is discharged from the gas zone 12 after the barrier is applied, it will not affect the pressure in the liquid zone 11, thus preventing large fluctuations in the liquid level. This keeps the liquid in a relatively stable state, allowing the liquid level sensor to monitor the liquid level in real time. The liquid level reflects the gas pressure inside the tank 10, and monitoring the liquid level is to ensure the stability and balance of the gas pressure inside the tank 10.

[0019] It should be noted that the space of the liquid zone 11 is smaller than that of the gas zone 12, thereby avoiding the impact on the liquid level when gas is discharged or enters. In addition, the tank 10 is also equipped with a water supply pipe 20 for replenishing liquid when the liquid level is low.

[0020] Furthermore, since the water inlet will impact the liquid at the bottom, it is easy to cause fluctuations in the liquid level in the liquid zone 11. To avoid this situation, several water distribution orifice plates 14 are provided at intervals in the liquid zone 11. Each water distribution orifice plate has several through holes. The water distribution orifice plates 14 block the liquid fluctuations between different areas and disperse them, thereby ensuring the stability of the liquid level.

[0021] Furthermore, since air may also enter the liquid zone 11, in order to avoid the accumulation of air and the resulting uncertain pressure, an auxiliary exhaust port 17 is provided at the top of the liquid zone 11. When it is necessary to exhaust the air in the liquid zone 11, the air can be exhausted through the auxiliary exhaust port 17 to ensure the accuracy of monitoring.

[0022] Furthermore, the liquid zone 11 is provided with an outlet 18 and connected to a drain pipe 19 to control the liquid to be discharged into a predetermined position. In order to avoid the siphon phenomenon at the rear end, the drain pipe 19 is set with a reduced diameter at the predetermined position, that is, the diameter of the pipe is reduced at the position, thereby avoiding the occurrence of the siphon phenomenon.

[0023] In summary, this application divides the interior of the tank 10 into two zones, allowing liquid to flow between them while blocking gas in the gas zone 12, thus ensuring stable liquid level and accurate monitoring. Furthermore, several water equalization orifice plates 14 are provided in the liquid zone 11. The water equalization orifice plates 14 reduce liquid level fluctuations caused when liquid enters the tank 10. At the same time, automatic control, automatic water replenishment, and automatic water drainage can be achieved through liquid level monitoring.

[0024] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
