Description

Technical Field

[0002] During boiler operation, steam and water sampling is a crucial step in monitoring boiler water quality and ensuring equipment safety.

[0003] Chinese patent CN222994061U discloses a boiler steam and water sampling device. The device uses an air inlet pipe to transport gas from the boiler to the cooling chamber, and a serpentine tube to facilitate gas condensation. A liquid pump can extract liquid from the boiler to flush impurities inside the serpentine tube. The device has a simple structure and can complete the condensation and conversion of liquid. However, the shape of the serpentine tube is relatively irregular, and the float may not be accurately guided during its internal movement, which may lead to jamming. The cooling chamber does not have a circulation method, and the serpentine tube is relatively short, which may lead to uneven cooling or low efficiency. Moreover, the device uses water from the boiler for flushing, which can easily leave a lot of impurities. Furthermore, the air inlet pipe cannot be flushed during the cleaning process. Therefore, a boiler steam and water sampling device is proposed. Summary of the Invention

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example: Refer to Figure 1-4 A boiler steam and water sampling device includes a boiler body 1, a controller 2 on the boiler body 1, a boiler feed inlet 3 on one side of the boiler body 1, a boiler discharge outlet 4 on the bottom side of the boiler body 1, a condenser box 15 on one side of the boiler body 1, a spiral condenser tube 14 inside the condenser box 15, a conveying pipe 7 connecting the boiler body 1 and the condenser box 15, a vertical pipe 18 at one end of the conveying pipe 7, a limit rod 21 installed inside the vertical pipe 18, a movable block 20 movably connected to the limit rod 21, a condensation collection ring 13 installed on the inner wall of the top of the boiler body 1 to recover the liquid condensed at the top of the boiler body 1, a collection tank inside the condensation collection ring 13, a liquid pump 5 installed on the outer side of the boiler body 1, an extraction pipe 6 connected to the liquid pump 5, the extraction pipe 6 including an upper pipe and a lower pipe, one end of the upper pipe connected to the liquid pump 5, and the other end connected to the collection tank to facilitate the extraction of the internal condensate.

[0017] Specifically, a liquid outlet 11 is provided on one side of the condenser 15 to facilitate the delivery of the condensed liquid. One end of the spiral condenser tube 14 is connected to the liquid outlet 11, and the other end of the spiral condenser tube 14 is connected to the outer surface of the bottom end of the vertical tube 18. The two are interconnected. The spiral condenser tube 14 is evenly distributed in the condenser 15 to achieve efficient condensation and liquefaction.

[0018] Furthermore, an installation block 17 is fixedly installed on the top surface of the condensing box 15, one end of the conveying pipe 7 is installed on the top surface of the boiler body 1, and the other end of the conveying pipe 7 is connected to the installation block 17, and the conveying pipe 7 is connected to the boiler body 1.

[0019] Furthermore, the bottom end of the vertical pipe 18 is fixedly installed inside the condenser box 15, and the top end of the vertical pipe 18 is connected to the bottom side of the mounting block 17. The limiting rod 21 is vertically installed at the center of the vertical pipe 18 to limit the movable block 20 and prevent jamming. A fixed block 19 is fixedly installed on the inner wall of the mounting block 17, and the movable block 20 is connected to the bottom side of the fixed block 19. The movable block 20 is a float that can float on the liquid. One end of the lower pipe is installed on the bottom side of the liquid pump 5, and the other end passes through the condenser box 15 and is connected to the vertical pipe 18. This facilitates efficient recovery of condensate while replenishing the liquid in the vertical pipe 18 to ensure the sealing state of the movable block 20.

[0020] In this embodiment, a liquid inlet end 12 is provided on one side of the condenser 15 to facilitate the continuous addition of liquid to the condenser 15. A circulation discharge pipe 9 is installed on the top surface of the condenser 15. The two sides of the circulation discharge pipe 9 are respectively connected to a first return pipe 8 and a second return pipe 10. The other end of the first return pipe 8 is connected to the conveying pipe 7, which acts as cooling water to reverse convey and flush the conveying pipe 7 and the boiler body 1. The other end of the second return pipe 10 is connected to the liquid outlet end 11 to facilitate the sealing of the movable block 20 during the reverse flushing. A control valve 16 is installed on both the first return pipe 8 and the second return pipe 10. A pump is connected to the outside of the circulation discharge pipe 9.

[0021] Working principle: External cooling water is placed into the condenser 15 through the liquid inlet 12. After it is full, it will flow out from the circulation discharge pipe 9 and be reintroduced into the liquid inlet 12 through the external circulation device. When the equipment takes steam and water samples, the gas will enter the vertical pipe 18 through the delivery pipe 7 and then be transferred to the spiral condenser 14. At this time, the gas will be condensed in the spiral condenser 14. During this period, the liquid pump 5 will draw the liquid collected by the condensation collection ring 13 into the vertical pipe 18. When there is an excess of condensed liquid in the spiral condenser 14, the condensed liquid will fill the vertical pipe 18. During the storage process, the movable block 20 will move upward with the height of the liquid level until it is connected to the bottom side of the fixed block 19 to seal the vertical pipe 18 and prevent the gas from continuously entering. When the liquid in the spiral condenser 14 is discharged, the movable block 20 will descend with the height of the liquid level. When cleaning the equipment, if the spiral condenser tube 14 needs to be cleaned, the control valve 16 on the first return pipe 8 is opened. Part of the liquid in the circulating discharge pipe 9 will enter the vertical pipe 18 through the first return pipe 8 and flow out from the liquid outlet 11 through the spiral condenser tube 14. The internal impurities will be flushed out at the same time. When cleaning the conveying pipe 7, the control valve 16 on the second return pipe 10 is opened to block the liquid outlet 11. The liquid will flow into the spiral condenser tube 14 and the vertical pipe 18 through the liquid outlet 11. When the liquid inside is full, the movable block 20 will block the channel in the mounting block 17. At this time, the control valve 16 on the first return pipe 8 is opened again. The liquid will flow upward through the conveying pipe 7, flushing the impurities in the conveying pipe 7 back into the boiler body 1 and flowing out from the boiler outlet 4.
