Description

Technical Field

[0001] This utility model relates to the field of thermal energy engineering, and in particular to a sampling cooler for boiler rooms. Background Technology

[0002] A sampling cooler for boiler rooms is a device used for cooling and sampling high-temperature media in boilers. Its core structure includes cooling pipes and a shell. The sample to be cooled flows through the pipes, while cooling water flows through the shell. Through heat exchange, the sample is cooled to 30-40°C. It is typically equipped with a filter and an exhaust vent to ensure safe and clean sampling, providing qualified samples for boiler water quality testing, etc., and belongs to the category of thermal energy engineering and industrial testing equipment.

[0003] A sampling cooler for boiler rooms mainly includes cooling pipes, an outer shell, cooling water inlet and outlet, sample inlet and outlet, as well as venting holes, a filter device, connecting flanges and mounting legs. Some models include manifolds or sampling valves. The structure is compact and ensures safe sampling.

[0004] Currently, traditional equipment lacks buffer components, allowing pressure fluctuations in the boiler sampling medium to directly impact the cooling pipes, easily causing fatigue cracking and unstable sampling flow, thus affecting detection accuracy. Most traditional equipment also lacks filtration components, allowing impurities to enter the cooling pipes with the medium, causing blockages, reducing heat exchange efficiency, and even damaging the equipment. Furthermore, impurities mixed into the sample can distort the detection data, failing to accurately reflect the boiler's operating status, increasing the risk of malfunctions and maintenance costs.

[0032] 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.

[0033] Reference Figures 2-4This utility model provides an embodiment of a sampling cooler for boiler rooms, comprising a frame 1, a cooling pipe inlet 2 at the bottom of the frame 1, a water inlet 3 at the top of one side of the frame 1, and a water outlet 4 at the bottom of one side of the frame 1. A water inlet pipe 5 is fixedly connected to the bottom of the cooling pipe inlet 2. A buffer assembly 6 is provided at the front end of the water inlet pipe 5. A filter assembly 7 is provided on one side of the buffer assembly 6. The filter assembly 7 filters impurities in the medium to be cooled, preventing blockage of the cooling pipe and other components, and ensuring a smooth sampling cooling process. It includes specific filtration structures such as T-type filters and filter screens. The filter assembly 7 includes a T-type filter 8. The T-type filter 8 performs preliminary filtration of the medium with the help of an internal filter barrel 9, intercepting larger particulate impurities. The T-type filter 8 has a filter barrel 9 inside. Flanges 10 are fixedly connected to both sides of the T-type filter 8. The flanges 10 are threaded to the front end of the water inlet pipe 5 on both sides.

[0034] A top cover 17 is fixedly connected to the top of the frame 1. The top cover 17 is fixedly connected to the top of the frame 1 by bolts 18. The top cover 17 is provided with a cooling pipe outlet 19. A sampling pipe 20 is fixedly connected to the cooling pipe outlet 19. A sampling valve 21 is fixedly connected to the sampling pipe 20. The sampling valve 21 controls the sampling process. When it is open, the cooled medium flows out for testing. When it is closed, it maintains the circulation and storage of the medium inside the equipment to ensure that the sampling is controllable. A cooling pipe 22 is provided inside the frame 1. A cooling pipe outlet 19 is fixedly connected to the top of the cooling pipe 22. A cooling pipe inlet 2 is fixedly connected to the bottom of the cooling pipe 22. The cooling pipe 22 is spiral. A sampling hole 23 is opened on the top cover 17.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The buffer assembly 6 includes a housing 11. The buffer assembly buffers the pressure impact when the medium to be cooled enters through a structure such as a piston 12 and a spring 13, protects the equipment, and stabilizes the medium flow rate and pressure 6. The housing 11 is fixedly connected to the top of the water inlet pipe 5. The piston 12 is slidably connected inside the housing 11. A spring 13 is fixedly connected to one side of the piston 12. A fixing plate 14 is fixedly connected to the end of the spring 13 away from the piston 12. The fixing plate 14 is fixedly connected to one side of the housing 11. The filter assembly 7 also includes a filter screen 15. The filter screen 15 is fixedly connected to a flange bolt 16. The flange bolt 16 is fixedly connected to the water inlet 3 and the water outlet 4.

[0036] Working Principle: First, the working principle of filter assembly 7 is based on a multi-level impurity interception mechanism. When the high-temperature sampling medium flows in from the inlet pipe 5, it first enters the T-type filter 8. The T-shaped structure causes the medium to flow in a directional manner within the filter, and larger particles of impurities settle to the bottom of the filter barrel 9 due to inertia. The filter barrel 9 uses a stainless steel sintered filter screen or a wedge-shaped filter screen. When the cooling water flows to the inlet 3 and outlet 4, the filter screen 15, fixed by the flange bolts 16, intercepts fine impurities. The flange 10 of the T-type filter 8 adopts a quick-release design, which allows the filter barrel 9 to be opened periodically for cleaning without interrupting the entire sampling process.

[0037] The buffer assembly 6 balances medium pressure fluctuations through spring 13 and piston 12. When high-pressure medium impacts the inlet pipe 5, the pressure pushes piston 12 inside the outer casing 11 to compress spring 13, thereby reducing the instantaneous pressure. During the compression process, spring 13 converts the kinetic energy of the medium into elastic potential energy. When the pressure drops, spring 13 rebounds, pushing piston 12 back to its original position, maintaining a stable flow rate. The fixed plate 14 provides rigid support for the spring, ensuring a stable and reliable buffering process. It can quickly respond to the water hammer effect during boiler start-up and shutdown, protect the cooling pipe 22 from high-pressure impacts, and ensure the accuracy of subsequent testing and the lifespan of the equipment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
