Description

Technical fields:

[0001] This utility model belongs to the field of boiler water quality testing and sampling, and particularly relates to a boiler water quality testing and sampling device. Background technology:

[0002] Boilers are commonly used in industrial production. During boiler operation, the water used must be inspected for quality. Poor boiler water quality can cause significant damage to the boiler, even leading to an explosion. Therefore, it is essential to regularly test boiler water quality, promptly identify any problems, and take appropriate measures to ensure the safe, reliable, and economical operation of the boiler.

[0003] Taking the hydrogen conductivity testing of boiler water as an example, boiler water sampling is first required. Water samples mainly include feedwater, boiler water, and condensate. However, in the actual boiler water sampling process, due to the dispersed pipelines corresponding to each water source, on-site quality inspectors need to frequently visit each sampling point to collect samples. This results in high labor intensity for the quality inspectors and a long sampling time, significantly reducing the efficiency of boiler water quality inspection. Furthermore, in this case, no splash prevention devices were installed at the sampling points, causing a large amount of sample water to splash onto the ground during sampling, further polluting the environment and wasting significant water resources. Summary of the Invention:

[0004] The purpose of this invention is to provide a boiler water quality testing and sampling device, which overcomes the shortcomings of the prior art and effectively solves the existing problems of time-consuming and laborious sampling by quality inspectors and environmental pollution caused by water splashing.

[0005] The present invention relates to a boiler water quality testing and sampling device, comprising several boiler water samplers installed side-by-side on the top wall of a frame, wherein the cooling water inlet pipes of the several boiler water samplers are connected to a cooling water supply main pipe, and the cooling water return pipes of the several boiler water samplers are connected to a cooling water return main pipe. A water collection tank is installed on the top wall of the frame, and an opening is provided on the top wall of the water collection tank. The outer port of the sampling pipe of the boiler water sampler extends through the opening into the inner cavity of the water collection tank.

[0006] Furthermore, several support arms are vertically installed along the length direction on the inner wall of the water collection tank, and a U-shaped bracket is installed at the outer end of the support arm. The U-shaped bracket is located directly below the outer port of the sample discharge pipe of the boiler water sampler.

[0007] Furthermore, a door panel is hinged at the sampling port of the water collection tank.

[0008] Furthermore, a water discharge pipe is connected to the water collection tank.

[0009] Furthermore, a sample cup placement slot is installed on the top wall of the frame, and the sample cup placement slot is located in front of the water collection tank.

[0010] The beneficial effects of this utility model are as follows: By centrally introducing the feedwater, boiler water, condensate, and other main components of the boiler into several boiler water samplers arranged in parallel for cooling and sampling, the multi-point sampling of boiler water is transformed into centralized single-point sampling, thereby reducing the labor intensity and time required for quality inspectors and improving the quality inspection efficiency of boiler water; the water collection tank can centrally collect the sample water splashed during the sampling process, which not only avoids the sample water from polluting the environment, but also realizes the recycling and reuse of water resources.

Detailed implementation method:

[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0017] like Figures 1 to 4As shown, the boiler water quality sampling device includes several boiler water samplers 2 installed side-by-side on the top wall of the frame 1. The cooling water inlet pipes 21 of each sampler 2 are connected to the cooling water supply main pipe 3, and the cooling water return pipes 22 of each sampler 2 are connected to the cooling water return main pipe 4. A water collection tank 5 is installed on the top wall of the frame 1, and an opening 6 is provided on the top wall of the water collection tank 5. The outer port of the sampling pipe 23 of each boiler water sampler 2 passes through the opening 6 and extends to the... Inside the water collection tank 5, several support arms 7 are vertically installed along the length direction on the side wall of the inner cavity of the water collection tank 5. A U-shaped bracket 8 is installed at the outer end of the support arm 7. The U-shaped bracket 8 is located directly below the outer port of the sample discharge pipe of the boiler water sampler 2. A door panel 9 is hinged at the sampling port 51 of the water collection tank 5. A water discharge pipe 10 is connected to the water collection tank 5. A sample cup placement slot 11 is installed on the top wall of the frame 1. The sample cup placement slot 11 is located in front of the water collection tank 5.

[0018] Specifically, by sequentially introducing the feedwater, boiler water, condensate, and other main components of the boiler into several boiler water samplers 2 arranged side by side for cooling treatment, the multi-point sampling of boiler water is transformed into centralized single-point sampling, thereby reducing the labor intensity and time required for quality inspectors and improving the quality inspection efficiency of boiler water.

[0019] In actual use, firstly, bypass pipes are connected to the main feedwater, boiler water, condensate and other conveying pipes involved in the boiler, and these multiple bypass pipes are connected in sequence to the inner ports of the discharge pipes 23 of several boiler water samplers 2. The main function of the boiler water sampler 2 is to cool the sampled water to avoid scalding the quality inspectors. The boiler water sampler 2 is an existing technology device and will not be described in detail here.

[0020] When quality inspectors take samples, they first place several sampling cups 12 into the water collection tank 5 through the sampling port 51, and align the sampling cups 12 with the outer port of the discharge pipe 23 of the boiler water sampler 2. At this time, the valves installed on the cooling water inlet pipe 21 and the cooling water return pipe 22 are opened, so that the cold water source in the cooling water supply main pipe 3 can enter the inner cavity of the boiler water sampler 2 and complete the return flow through the cooling water return main pipe 4, thereby achieving a circulating cooling effect. Taking boiler feedwater sampling as an example, the boiler feedwater... The valve of the discharge pipe 23 of the corresponding single boiler water sampler 2 is opened, so that the high-temperature boiler feedwater flows into the spiral discharge pipe 23 and exchanges heat with the cooling water circulating in the inner cavity of the boiler water sampler 2. The cooled boiler feedwater finally flows into the sampling cup 12 through the outer end of the discharge pipe 23. After sampling, the valve of the discharge pipe 23 is closed and the sampling cup 12 is taken out. Repeating the above operation can complete the centralized single-point rapid sampling of feedwater, boiler water, condensate and other water involved in the boiler.

[0021] During the sampling process, the water collection tank 5 can collect the water splashed during the sampling process, preventing the sampled water from falling to the ground and causing environmental pollution and water waste. The collected water is transported to the water treatment system through the discharge pipe 10. Quality inspectors can attach the corresponding clip of the sampling cup 12 to the U-shaped bracket 8, thereby preventing the cup body of the sampling cup 12 from directly contacting the impurities collected in the water collection tank 5, further protecting the sampling cup 12 and the obtained sample water from secondary contamination. During sampling, the door panel 9 can be lowered to further prevent the sample water from splashing to the ground through the sampling port 51. After the sampling cup 12 has obtained the sample water, it can be removed from the U-shaped bracket 8 and temporarily placed in the sample cup placement slot 11. This not only prevents cross-contamination between several sampling cups 12 in the water collection tank 5, but also stabilizes the sampling cup 12 that has obtained the sample water, preventing it from accidentally tipping over.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
