Abstract
Description
Technical Field
[0001] This utility model relates to the field of flue gas detection pipeline cleaning technology, specifically, to an elastic cleaning rod and cleaning device for a sampling rod section used for desulfurization flue gas detection. Background Technology
[0002] The Continuous Online Monitoring System (CEMS) for flue gas in thermal power plants primarily monitors the gas composition in emitted air. By adjusting the denitrification ammonia injection system, electrostatic precipitator control parameters, and desulfurization process, it ensures that delayed emission targets meet requirements. The safe, reliable, and stable operation of the CEMS is crucial. The sampling rod of the on-site CEMS equipment is installed in the boiler flue gas duct. It mainly extracts flue gas, and the gas to be measured is transferred to a gas analyzer by the CEMS sampling pump for real-time measurement of flue gas emission data.
[0003] Because the flue gas contains ammonia, it easily causes ammonium salt crystallization in the sampling probe, affecting the accuracy of the measurement data. Furthermore, the sampling port diameter of the on-site equipment is approximately 7mm, and the diameter of the tube section from the sampling port to the sampling rod is 29mm, with a length of 1.5m; the inlet is small, while the interior is large. The probe cannot be thoroughly cleaned during equipment operation. Cleaning can only be done after power is off, which is time-consuming and involves repeated disassembly, installation, and power restoration, posing a risk of equipment damage.
[0004] Therefore, for devices with small inlets and large interiors in the sampling rod tube section for desulfurization flue gas detection, there is an urgent need to develop a solution that can achieve internal solid cleaning without interrupting power or disassembly. Summary of the Invention
[0005] The technical problem this invention aims to solve is how to achieve internal solid cleaning of a sampling rod tube section for desulfurization flue gas detection that has a small inlet and a large interior, without interrupting power or disassembling it.
[0006] To solve the above-mentioned technical problems, according to one aspect of this utility model, an elastic cleaning rod for a sampling rod section for desulfurization flue gas detection is provided, comprising: a round rod, the round rod comprising a control section, an extension section, and a spring section; and a spring piece, the spring piece being an elastic elongated strip with two ends, both ends of which are fixedly connected to the spring section of the round rod, wherein the length of the spring piece between the connection points with the round rod is greater than the length of the round rod between the connection points, thereby forming an arc shape at the connection points with the round rod that is not in contact with the spring section of the round rod; wherein the sampling rod section for desulfurization flue gas detection has a design for the insertion of a detection probe. The diameter of the round bar plus the thickness of the spring piece are smaller than the aperture of the sampling rod tube section used for desulfurization flue gas detection. This ensures that the spring piece can pass through the aperture and extend into the sampling rod tube section. The distance between the arc of the spring piece and the maximum distance point of the round bar is greater than the aperture of the equipment. Due to the elastic deformation of the spring piece, it has an arc. When passing through the small aperture, the spring piece automatically extends along the round bar. After passing through, the spring piece automatically springs open, allowing the spring piece of the round bar to pass through the aperture and extend into the sampling rod tube section for desulfurization flue gas detection. After the spring piece enters the sampling rod tube section, the spring piece returns to its arc shape. Operating the spring piece control section causes the elastic cleaning rod to rotate or vibrate, thereby achieving internal cleaning of the sampling rod tube section.
[0007] According to an embodiment of the present invention, the two ends of the spring sheet can be fixedly connected to the spring segment of the round bar by welding or strapping.
[0008] According to an embodiment of the present invention, the thickness of the two sides of the spring piece parallel to the round rod can be reduced to facilitate cleaning of particulate matter and adhering dirt from the inner surface of the sampling rod tube section.
[0009] According to an embodiment of this utility model, the round bar can be a rigid round bar.
[0010] According to an embodiment of the present invention, the round bar can be a solid cylindrical structure.
[0011] According to embodiments of this utility model, the round bar and the spring can be made of stainless steel.
[0012] According to another aspect of the present invention, a cleaning device is provided, comprising: an elastic cleaning rod for a sampling rod section for detecting desulfurized flue gas as described above; and an operating device for operating the elastic cleaning rod by a control section of a round bar to clean the object to be cleaned.
[0013] According to an embodiment of this utility model, the operating device can be a portable pistol drill.
[0014] Compared with the prior art, the technical solution provided by the embodiments of this utility model can achieve at least the following beneficial effects:

[0021] Figure 1 This is a schematic diagram showing the elastic cleaning rod and cleaning device of the sampling rod section used for desulfurization flue gas detection.
[0022] like Figure 1 As shown, the elastic cleaning rod of the sampling rod section used for desulfurization flue gas detection includes: a round rod 1 and a spring 2.
[0023] The round bar 1 includes a control section, an extension section and a spring sheet 2 section in sequence; the spring sheet 2 is a long strip with elasticity, and the spring sheet 2 has two ends, both of which are fixedly connected to the spring sheet 2 section of the round bar 1.
[0024] Among them, the length of the spring piece 2 between the connection points with the round rod 1 is greater than the length of the round rod 1 between the connection points, so that the part of the spring piece 2 between the connection points with the round rod 1 forms an arc shape that is not in contact with the spring piece 2 segment of the round rod 1.
[0025] The sampling rod tube section used for desulfurization flue gas detection has an equipment hole for the detection probe to extend into. The sum of the diameter of the round rod 1 and the thickness of the spring piece 2 is smaller than the diameter of the equipment hole of the sampling rod tube section used for desulfurization flue gas detection, thereby ensuring that the spring piece 2 can extend into the sampling rod tube section through the equipment hole.
[0026] The distance between the arc-shaped spring piece 2 and the maximum distance point of the round rod 1 is greater than the diameter of the equipment hole. Due to the elastic deformation of the spring piece 2, the spring piece 2 has an arc. When passing through the small diameter, the spring piece 2 automatically extends into the round rod 1. After passing through, the spring piece 2 automatically springs open, allowing the spring piece 2 section of the round rod 1 to extend into the sampling rod tube section of the desulfurization flue gas detection through the equipment hole. After the spring piece 2 section enters the sampling rod tube section, the spring piece 2 returns to its arc shape. The operation of the spring piece 2 control section causes the elastic cleaning rod to rotate or vibrate, thereby achieving the internal cleaning of the sampling rod tube section.
[0027] According to one or more embodiments of the present invention, the two ends of the spring piece 2 are fixedly connected to the spring piece 2 section of the round bar 1 by welding or strapping.
[0028] According to one or more embodiments of the present invention, the thickness of the two sides of the spring piece 2 parallel to the round rod 1 is reduced to facilitate the cleaning of particulate matter and adhering dirt from the inner surface of the sampling rod tube section.
