Description

Technical Field

[0001] This utility model relates to a steam-water heat exchange device, and more particularly to a boiler steam-water sampling device. Background Technology

[0002] Steam boilers are widely used in China. To ensure the safe operation of the boiler, it is necessary to monitor the quality of the boiler steam and water during the boiler operation process. The high temperature of the boiler steam and water cannot be directly sampled for testing. Usually, the steam and water are cooled by a steam and water sampling device before sampling for water quality testing. Currently, most of the steam and water sampling devices commonly used in China have problems such as poor cooling effect, excessively high water temperature at the sampling port, and even steam spraying. Improper operation can easily cause burns and excessively long sampling time. Summary of the Invention

[0003] The purpose of this invention is to design and manufacture a soda sampling device to achieve rapid cooling of high-temperature soda and to make the sampling operation safe and convenient.

[0004] This utility model is implemented as follows: This boiler steam and water sampling device consists of an outlet pipe (1), an inlet pipe (2), an inlet pipe (3), a spring-shaped coil (4), a top cover plate (5), a cylinder (6), a water receiving pipe (7), a drain pipe (8), a fixed bracket (9), a guide pipe (10), and a partition plate (11). Low-temperature cooling water enters the guide pipe (10) from the inlet pipe (2) to cool the inlet pipe (3), then enters the cylinder (6) to cool the spring-shaped coil (4), and flows out from the outlet pipe (1) after passing through the partition plate (11); high-temperature steam and water enter the spring-shaped coil (4) from the inlet pipe (3), and after rapid cooling, water quality samples are taken for testing.

[0005] The water outlet pipe (1) is connected to the top cover plate (5) and the water outlet is located at the top.

[0006] The water inlet pipe (2) is connected to the water guide pipe (10), and the water inlet is located at the top.

[0007] The steam inlet pipe (3) adopts a trumpet-shaped expansion pipe structure, which reduces the steam flow rate, increases the heat exchange area, and enhances the cooling effect.

[0008] The water pipe (10) is equipped with a steam inlet pipe (3) inside and a spring-shaped coil (4) outside.

[0009] The spring-shaped coil (4) is connected to the steam inlet pipe (3). The coil is made of Φ14 stainless steel seamless pipe.

[0010] The cylinder (6) is made of steel pipe, with an arc-shaped partition (11) inside and a drain pipe (8) at the bottom. The cylinder (6) is connected to the top cover plate (5) with flange bolts.

[0011] The fixed bracket (9) is made of channel steel and is connected to the cylinder (6).

[0012] The water inlet pipe (7) adopts a cylindrical funnel structure and is connected to the cylinder (6).

[0013] The working principle of this utility model is as follows: Low-temperature cooling water enters the water guide pipe from the water inlet pipe to cool the high-temperature steam and water that has expanded in the steam inlet pipe. Then, it enters the cylinder from the bottom of the water guide pipe to further cool the spring-shaped coil. The low-temperature cooling water flows out from the water outlet pipe after passing through the baffle. The high-temperature steam and water is rapidly cooled by the low-temperature water after passing through the steam inlet pipe and the spring-shaped coil. After that, it is discharged and sampled for water quality testing. Excess water is discharged through the water receiving pipe.

[0014] The technical effects of this utility model are as follows: This utility model adopts a two-stage cooling system. The first stage is the cooling of the steam inlet pipe, which adopts a trumpet-shaped expansion structure, reducing the flow rate of high-temperature steam and water, increasing the heat exchange area, and enhancing the heat exchange effect. The second stage is the cooling of the spring-shaped coil. The coil is designed with a small diameter and long flow path, allowing the high-temperature steam and water to stay in the sampler for a long time. By controlling the appropriate flow rate and velocity of the low-temperature cooling water, the high-temperature steam and water can be cooled down quickly, achieving the purpose of rapid sampling and testing.
