[0002] After prolonged use, the sampling tubes of emission equipment will be contaminated by exhaust gas. If the amount of contamination is large, the resulting deposits can pollute the pre-filter of the emission equipment and easily contaminate the analyzer, which may lead to the analyzer's testing failure.

[0003] Currently, existing cleaning equipment (such as ultrasonic cleaners) requires placing the sampling tube inside the cleaning chamber. However, since the sampling tube contains temperature sensor cables, insulation layers, and heat insulation layers, this method can damage these components, thus affecting the subsequent operation of the discharge equipment.

[0004] In summary, how to clean the sampling tube of an emission analyzer without affecting other structures on the sampling tube is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0029] The core of this utility model is to provide a sampling tube cleaning device and system for emission analyzers.

[0030] Please refer to Figure 1 .

[0031] The sampling tube cleaning device for the emission analyzer provided by this utility model includes a cleaning tank 1. The cleaning tank 1 is provided with an outlet and a return outlet. The outlet is connected to one end of the sampling tube 4 through a first connecting pipe 2, and the return outlet is connected to the other end of the sampling tube 4 through a second connecting pipe 3. A pump body 5 is provided on the first connecting pipe 2 so that the cleaning liquid in the cleaning tank 1 flows into the sampling tube 4 for rinsing.

[0032] Specifically, the pump body 5 continuously pumps liquid containing a special cleaning agent from the cleaning tank 1 into the sampling tube 4 through the first connecting pipe 2. This liquid flushes the inner wall of the sampling tube 4, carrying away contaminants along the liquid flow. The liquid then flows back into the cleaning tank 1 through the second connecting pipe 3. The continuous pumping of the cleaning liquid by the pump body 5 effectively cleans the inner wall of the sampling tube 4. This circulating cleaning method significantly improves the cleaning effect and reduces water waste.

[0033] The aforementioned emission analyzer sampling tube cleaning device uses pump 5 to provide power to push the liquid containing special cleaning agent in the cleaning tank 1 into the sampling tube 4 through the first connecting pipe 2, so that the liquid containing special cleaning agent rinses the sampling tube 4. This method will not damage the temperature sensor cable, insulation layer, or heat insulation layer on the sampling tube 4. The rinsed liquid carries the pollutants back into the cleaning tank 1 to form a cycle. Through repeated rinsing, the sampling tube 4 is cleaned.

[0034] The sampling tube cleaning device for emission analyzers provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0035] In one specific implementation, reference is made to... Figure 1 The cleaning tank 1 is equipped with a filter device, which is used to filter out large particulate impurities in the liquid flowing in from the return water inlet.

[0036] Specifically, since the liquid flowing into the cleaning tank 1 through the return water inlet carries contaminants from the inner wall of the sampling tube 4, the filter device can effectively filter and isolate the impurities and contaminants entering through the return water inlet, thereby preventing them from flowing back into the sampling tube 4 with the cleaning liquid, thus improving the overall cleaning effect of the device.

[0037] Based on any of the above embodiments, refer to Figure 1 The filtration device includes a filter screen 6 vertically installed in the cleaning tank 1. The filter screen 6 is located between the return water port and the outlet water port, and the height of the filter screen 6 is higher than the liquid level of the cleaning liquid in the cleaning tank 1.

[0038] Specifically, the filter screen 6 is vertically installed between the return water inlet and the outlet water outlet to isolate the contaminants in the liquid containing impurities that enters the cleaning tank 1 through the return water inlet, preventing them from moving to the outlet water outlet with the liquid. The filter screen 6 can be a commonly used filter screen that can filter and adsorb contaminant particles on the inner wall of the sampling tube 4.

[0039] Based on any of the above embodiments, refer to Figure 1 The pump body 5 is a pneumatic diaphragm pump driven by compressed air, and a control valve is installed between the pump body 5 and the outlet.

[0040] Specifically, pump body 5 can be driven by a diaphragm pump using compressed air at approximately 6 bar. This compressed air draws liquid into the sampling tube 4 and cleans it. After cleaning the sampling tube 4, some cleaning fluid remains on its inner wall. This fluid adheres to the inner wall and is difficult to remove. Using a pneumatic diaphragm pump driven by compressed air, after repeatedly rinsing and cleaning the sampling tube 4, the control valve disconnects the liquid supply from the cleaning tank 1 to pump body 5. Thus, when pump body 5 continues to operate, since it cannot draw in liquid, the compressed air generated by pump body 5 is directly introduced into the sampling tube 4, drying the residual liquid on the inner wall of the sampling tube 4 and further improving the cleaning effect of the device.

[0041] It should be noted that the cleaning of sampling pipe 4 is generally located in the equipment room on the second floor. Using a pneumatic pump as the power pump for cleaning the pipeline reduces the limitations of using an electric pump in terms of power supply location, and allows for on-site air intake, which is more convenient. Furthermore, the pneumatic pump has a silencer, resulting in less environmental noise pollution during operation.

[0042] Based on any of the above embodiments, refer to Figure 1 The cleaning tank 1 is equipped with a drain structure, which is used to discharge the used cleaning solution in the cleaning tank 1 to the outside of the cleaning tank 1.

[0043] Specifically, after the device repeatedly rinses the sampling tube 4, there are a lot of contaminants inside the cleaning box 1, so it needs to be replaced every certain period of time. Adding a drainage structure can effectively drain the liquid mixed with contaminants from the cleaning box 1, preparing for the next cleaning of the sampling tube 4.

[0044] Based on any of the above embodiments, refer to Figure 1 The sewage discharge structure includes a sewage outlet 7 at the bottom of the cleaning tank 1. The ground of the cleaning tank 1 is inclined toward the sewage outlet 7 so that the cleaning liquid in the cleaning tank 1 is discharged along the sewage outlet 7.

[0045] Specifically, the sewage outlet 7 can be opened in the middle of the bottom of the cleaning tank 1, and the four sides of the bottom of the cleaning tank 1 are inclined downward towards the sewage outlet. Thus, after the sewage outlet 7 is opened, the liquid in the cleaning tank 1 flows towards the sewage outlet 7, facilitating the complete discharge of the liquid in the cleaning tank 1.

[0046] Based on any of the above embodiments, a moving component is provided on the cleaning tank 1 to enable the cleaning tank 1 to change its position through the moving component.

[0047] Specifically, the provision of the moving component facilitates the staff to move the cleaning tank 1, thus facilitating the operation and maintenance of the operator.

[0048] Furthermore, the moving component includes a plurality of steering wheels fixedly arranged at the bottom of the cleaning tank 1. The steering wheels can achieve precise control of the movement of the cleaning tank 1 and can move in multiple directions, further enhancing the overall convenience of the device.

[0049] A sampling tube cleaning system for an emission analyzer provided by the present utility model includes the above-mentioned emission analyzer sampling tube cleaning device and the sampling tube 4, and further includes a water supply module, a cleaning agent supply module, a cleanliness detection module, and a control panel. The water supply module is connected to the cleaning tank 1 and is used to supply soft water to the cleaning tank 1. The cleaning agent supply module is connected to the cleaning tank 1 and is used to supply cleaning agent to the cleaning tank 1. The cleanliness detection module is connected to the second communication pipeline 3 and is used to detect the cleanliness of the return water in the second communication pipeline 3. The control panel is used to control the cleaning device, the water supply module, the cleaning agent supply module, and the cleanliness detection module.

[0050] Specifically, the water supply module and the cleaning agent supply module are used in cooperation to supply water and cleaning agent to the cleaning tank 1 in the cleaning device. The cleanliness detection module monitors the cleanliness of the return water in the second communication pipeline 3 in real time. When the cleanliness meets the requirements, the cleaning device can be controlled to stop, further enhancing the cleaning effect of the system and the visualization of the cleaning effect. The control panel realizes the interlocking control between multiple modules in the system.

[0051] Optionally, the water supply module and the cleaning agent supply module can be integrated into one. The integrated new module can preferentially mix water and cleaning agent and then supply them to the cleaning tank 1 after mixing.

[0052] The aforementioned sampling tube cleaning system for the emission analyzer integrates a water supply module, a cleaning agent supply module, a cleanliness detection module, and a control panel. Through efficient coordination, it achieves precise and comprehensive cleaning of sampling tube 4. The system not only intelligently controls the cleaning process, monitoring the cleanliness of the return water in real time and automatically stopping when the requirements are met, thereby improving the visualization of cleaning results and the effective utilization of resources, but also offers multiple advantages such as energy saving and environmental protection, improved analytical accuracy, and ease of maintenance, providing strong technical support for environmental protection and pollution control.

[0053] Based on any of the above embodiments, the emission analyzer sampling tube cleaning system also includes a waste liquid treatment module, which is used to recycle and treat the waste liquid in the cleaning tank 1.

[0054] Specifically, after the cleaning device repeatedly rinses the sampling tube 4, there are a lot of contaminants inside the cleaning tank 1, so it needs to be replaced every certain period of time. The addition of a waste liquid treatment module can effectively recycle and treat the liquid mixed with contaminants in the cleaning tank 1, in preparation for the next cleaning of the sampling tube 4.

[0055] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0056] The above provides a detailed description of the sampling tube cleaning device and system for an emission analyzer provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
