Description

Technical Field

[0001] This utility model relates to the field of cold box start-up technology, specifically a dew point analysis device for cold box start-up. Background Technology

[0002] The principle of a dew point analyzer is to use a sensor with nanopore technology to measure the number of water molecules entering the micropores. The number of water molecules entering the micropores is directly proportional to the water pressure of the gas around the sensor. The water pressure depends on the water content in the gas and the total pressure of the gas. Therefore, when the analyzer knows the total pressure of the gas, it can calculate the water content. Portable dew point meters can measure trace amounts of water in various gases and are suitable for various online analysis applications with strict requirements for water content control. The economical and universal solution can meet the control requirements of various industrial processes.

[0003] The existing Chinese utility model patent with publication number CN221100577U discloses a portable dew point analyzer, including a sampling host, a spring wire, a sampler, and a telescopic rod. A socket is fixedly installed on the top of the sampling host, and one end of the spring wire has a plug corresponding to the socket. The sampler is connected to the sampling host via the spring wire, and a probe for detecting dew point is installed on the top of the sampler. A straight-tube threaded sleeve is installed on the outer wall of the sampler, and one end of the telescopic rod is installed inside the straight-tube threaded sleeve. In use, the portable dew point analyzer detects the dew point through the probe on the top of the sampler. The detection result is transmitted to the screen of the sampling host via the spring wire and displayed. In special scenarios, the top of the inner tube of the telescopic rod can be installed inside the straight-tube threaded sleeve. Then, by holding the anti-slip rubber strip, the inner tube of the telescopic rod can be extended, causing the probe to move until it reaches the designated area for detection. After detection, the inner tube of the telescopic rod is retracted, and the probe is placed in the protective sleeve to prevent contamination.

[0004] The existing dew point analysis point at the pressurization end of the gas expander is a manual analysis point, which requires manual operation during testing, which is very inconvenient. At the same time, because the gas flow rate inside the expander is fast during use, the probe may be damaged by the airflow hitting the tube wall of the analysis point during manual operation.

[0006] To address the shortcomings of existing technologies, this invention provides a dew point analysis device for cold box startup, which has advantages such as reducing manual operation and avoiding probe damage, thus solving the aforementioned technical problems.

[0011] As a preferred embodiment of this utility model, the inner wall of the connecting column is provided with a groove structure, and one end of the connecting column is provided with an opening structure that fits into the probe; the connecting column can restrict the position of the sealing filler.

[0012] As a preferred embodiment of this utility model, the limiting plate and the connecting column form a sliding connection. The center of the limiting column is provided with an opening structure that fits into the probe, and the outer side of the limiting column is provided with a thread that fits into the groove of the inner wall of the connecting column.

[0013] As a preferred embodiment of this utility model, the limiting post and the connecting post form a movable connection, the sealing ring is located between the limiting post and the connecting post, and the probe is installed at the center of the connecting post through the limiting post; the sealing ring can play a sealing role.

[0014] As a preferred embodiment of this utility model, the bottom end of the probe is inserted and installed in the center of the connecting tube through the opening structure at the bottom end of the connecting column, and the bottom end of the probe is located in the center of the connecting tube; the probe facilitates the analyzer to detect the gas.

[0015] Compared with the prior art, this utility model provides a dew point analysis device for cold box startup, which has the following beneficial effects:

[0016] 1. This utility model features a connecting column with a grooved inner wall and an opening at one end for engaging with a probe. A sliding connection is established between the limiting plate and the connecting column.

A movable connection is formed between the limiting column and the connecting column. A sealing ring is located between the limiting column and the connecting column. The probe is installed at the center of the connecting column via the limiting column. During tightening of the limiting column, the limiting plate moves towards the bottom of the connecting column, compressing the sealing filler and filling the gap between the probe and the connecting column. This method restricts the probe's position, allowing airflow to pass through the bottom of the probe for gas detection. This prevents the probe from being driven by the airflow and impacting the analysis point wall, thus avoiding probe damage.

The interface facilitates the transmission of detection data. This method reduces manual operation after the device is installed, and the detection data can be transmitted remotely through the interface and data cable after the analyzer is started.
