Description

Technical Field

[0001] This utility model relates to the technical field of water tank water quality monitoring equipment, specifically to a water tank status detection device for boiler flue gas waste heat utilization systems. Background Technology

[0002] In existing boiler flue gas waste heat recovery systems, open-type water tanks (such as the ECO-SF1 type tank) are often used as storage devices for the heat medium or working fluid. These tanks typically have a standard interface on the upper part of the tank for installing a level gauge to monitor the liquid level. However, due to the structural design of this single interface, these tanks have significant functional limitations: they can only obtain the single parameter of liquid level and cannot simultaneously and effectively monitor water quality conditions (such as turbidity, suspended solids content, etc.).

[0003] In actual operation and maintenance, operators often need to promptly grasp other key status information besides the liquid level, such as whether the water is polluted, whether there are corrosion products or impurities accumulating, and whether the liquid transparency is normal. To expand water quality monitoring functionality beyond liquid level monitoring using existing technology, additional mounting holes are typically required on the water tank to install devices such as turbidimeters and sampling valves. This not only increases the difficulty of structural modification and system complexity but may also introduce new leakage risks and adversely affect the strength of the water tank itself.

[0004] Therefore, how to provide an integrated monitoring solution that is compact, reliable, and easy to observe, while maintaining the original structure of the water tank as much as possible and without significantly increasing additional openings, so as to enable intuitive and convenient monitoring of liquid level and water quality status at the same time, thereby improving the overall efficiency of operation and maintenance and the reliability of the system, has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The present invention aims to provide a water tank status detection device for boiler flue gas waste heat utilization systems, so as to solve the problem that existing water tanks cannot effectively monitor the liquid level and water quality status at the same time because they only have a single opening.

[0006] To achieve the above objectives, this utility model provides a water tank status detection device for a boiler flue gas waste heat utilization system, comprising: Main water tank; The auxiliary water tank is fluidly connected to the main water tank through a connecting pipe, so that the main water tank and the auxiliary water tank form a communicating vessel; A glass tube, made of transparent material, is installed along the height of the auxiliary water tank on the side wall of the auxiliary water tank. Its two ends are respectively connected to the auxiliary water tank through connectors, so that the glass tube is in communication with the internal fluid of the auxiliary water tank, thereby forming an observation channel for visually observing the liquid level and water quality inside the auxiliary water tank. The sampling port is located at the lower end of the auxiliary water tank or on the connector near the lower end of the glass tube, and is used to extract liquid samples.

[0007] Through the above technical solution, the water tank status detection device for boiler flue gas waste heat utilization system of this utility model effectively solves the problem that the existing water tanks cannot effectively monitor the liquid level and water quality status at the same time because they only have a single opening, and realizes the integrated monitoring of liquid level and water quality.

[0011] Furthermore, the bottom of the auxiliary water tank and the bottom of the main water tank are located on the same horizontal plane, and the auxiliary water tank and the main water tank have the same height.

[0012] Furthermore, the connector includes a bent pipe with openings at both ends, one end of which is connected to the glass tube and the other end of which is connected to the auxiliary water tank.

[0013] Furthermore, the connecting pipe is connected to the bottom or lower side of the main water tank and the auxiliary water tank.

[0014] Furthermore, the sampling port is equipped with an openable and closable sealing structure; the sealing structure is a plug valve, a ball valve, or a sealing nut.

[0020] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0021] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] This utility model provides a water tank status detection device for boiler flue gas waste heat utilization systems, such as... Figure 1 As shown, the water tank status detection device for the boiler flue gas waste heat utilization system includes a main water tank 1, an auxiliary water tank 3, a glass tube 4, and a sampling port 6.

[0024] The auxiliary water tank 3 is fluidly connected to the main water tank 1 via a connecting pipe 2, thus forming a communicating vessel between the main water tank 1 and the auxiliary water tank 3. Both the main water tank 1 and the auxiliary water tank 3 have openings at their tops or top sidewalls that connect to the outside. A glass tube 4, made of transparent material, is positioned along the height of the auxiliary water tank 3 on its sidewall, with both ends connected and fixed to the auxiliary water tank 3 via connectors, allowing fluid communication between the glass tube 4 and the interior of the auxiliary water tank 3. This forms an observation channel for visually observing the liquid level and water quality inside the auxiliary water tank 3. The sampling port 6 is located at the lower end of the auxiliary water tank 3 or on a connector near the lower end of the glass tube 4, and is used to extract liquid samples.

[0025] Thus, the water tank status detection device for boiler flue gas waste heat utilization system of this utility model can simultaneously monitor the liquid level change and water quality status in the main water tank 1. Specifically, by observing the liquid level in the glass tube 4, the liquid level in the auxiliary water tank 2 can be roughly determined, thereby indirectly reflecting the liquid level in the main water tank 1. At the same time, the water quality status inside the glass tube 4, i.e., the water quality status in the auxiliary water tank 3, can be observed through the glass tube 4, indirectly reflecting the water quality status (e.g., turbidity) in the main water tank 1. If necessary, the sampling port 6 can be opened to collect a portion of the liquid for further analysis to obtain a more accurate water quality result.

[0026] The connecting pipe 2 is equipped with a valve for controlling the liquid flow between the main water tank 1 and the auxiliary water tank 3. The purpose of installing the valve on the connecting pipe 2 is threefold: first, it allows for temporary disconnection for maintenance or component replacement; second, it allows for flow rate adjustment, which may be used to control the rate of liquid level balancing; and third, it allows for complete isolation of the two water tanks under certain special circumstances.

[0027] To ensure sufficient liquid flow and accurate reflection of liquid level, the connecting pipe 2 is connected to the bottom or lower side of the main water tank 1 and the auxiliary water tank 3.

[0028] To clearly indicate the entire range of liquid level changes within the auxiliary water tank 3, the glass tube 4 extends from the top surface to the bottom surface of the auxiliary water tank 3. Furthermore, to ensure the accuracy and consistency of the liquid level indication, the bottom of the auxiliary water tank 3 and the bottom of the main water tank 1 are located on the same horizontal plane, and the auxiliary water tank 3 and the main water tank 1 are at the same height.

[0029] In one optional embodiment, the connector is a bent pipe with openings at both ends. One end of the bent pipe is connected to the glass tube 4, and the other end is connected to the auxiliary water tank 3.

[0030] In one optional embodiment, the sampling port is equipped with an openable and closable sealing structure, which may specifically be a plug valve, a ball valve, a sealing nut, etc.

[0031] To facilitate direct reading of the liquid level, liquid level markings can be printed or etched on the surface of the glass tube 4. However, it should be noted that another important function of the glass tube 4 is to observe water quality (such as turbidity). If liquid level markings are printed or etched on the glass tube 4, the observer's view may be obstructed, and the color of the markings may cause the observer to misjudge the water quality, resulting in visual interference.

[0032] Therefore, in an optional embodiment of this invention, a liquid level sensor 5 (e.g., a magnetic float level gauge) is added to detect the liquid level in the auxiliary water tank 3 and output a liquid level signal. Based on the liquid level sensor 5, even if the glass tube 4 has no graduations, liquid level data can still be acquired, and the results are more accurate than visual observation. This design separates the digital measurement of liquid level from the intuitive visual observation of water quality, avoiding visual interference, ensuring the accuracy of water quality observation, and realizing remote transmission and automated monitoring of liquid level data.

[0033] In one optional embodiment, in addition to the liquid level sensor 5, a water quality sensor (such as a turbidity sensor) is further added to detect the liquid level in the auxiliary water tank 3 and to detect the water quality in the auxiliary water tank 2. Based on the configuration of the liquid level sensor 5 and the water quality sensor, more accurate liquid level and water quality data can be provided to verify visual inspections, forming a double guarantee. Furthermore, by transmitting the data read by the liquid level sensor 5 and the water quality sensor to a data center, data support can be provided for remote monitoring, automated operation, front-end and back-end operations, and system decision-making.

[0034] This utility model provides a variety of specific implementation methods for the water tank status detection device in boiler flue gas waste heat utilization systems, adapting to different operating conditions, such as: Specific implementation method 1: The liquid level and water quality can be directly judged through the glass tube 4, which is suitable for working conditions where the accuracy requirements are not high and on-site rapid inspection is required.

[0035] Specific implementation method 2: The liquid level is read through the graduated glass tube 4 and the water quality is roughly judged. This method is suitable for occasions where the accuracy of the liquid level reading is required and the water quality judgment is not required.

[0036] Specific implementation method three: Based on specific implementation methods one and two, a liquid level sensor 5 is added to realize the accurate acquisition and remote transmission of liquid level data, which is suitable for systems with high-precision liquid level monitoring requirements or data interface integration.

[0037] Specific Implementation Method Four: Based on Specific Implementation Method Three, a water quality detection sensor, such as a turbidity sensor, is added to achieve comprehensive digital monitoring of liquid level and water quality. This method is suitable for application scenarios with high requirements for data accuracy, automation level, and remote monitoring.

[0038] In summary, the water tank status detection device for boiler flue gas waste heat utilization system of this utility model achieves integrated and intuitive monitoring of liquid level and water quality status while maintaining the original structure of the water tank as much as possible and without significantly increasing additional openings, effectively improving the monitoring efficiency and operational reliability of the boiler flue gas waste heat utilization system.

Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0040] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0041] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
