[0002] Desulfurization towers are important equipment for removing harmful gases such as sulfur dioxide from flue gas. Traditional desulfurization towers have the following three technical defects during operation: (1) Difficulty in monitoring scaling and clogging: Areas such as the packing layer and spray layer inside the tower are prone to scaling due to sulfide deposition or slurry crystallization, which leads to a decrease in mass transfer efficiency or even clogging. Traditional desulfurization towers lack direct monitoring methods and require manual inspection after shutdown, which affects production efficiency; (2) Unstable desulfurization efficiency: Parameters such as desulfurization liquid circulation volume and sulfur capacity are difficult to adjust dynamically, resulting in fluctuations in desulfurization efficiency; (3) High maintenance costs: Traditional cleaning processes require frequent shutdowns and the use of robots or high-pressure cleaning equipment, which are complex to operate and costly.
[0003] While some existing desulfurization towers are equipped with sensors or monitoring devices, these devices are costly and prone to failure in certain harsh environments. Therefore, how to install a simple and practical observation device on the desulfurization tower has become an urgent problem for those skilled in the art. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] The attached figure shows a specific embodiment of this utility model. This embodiment aims to provide a desulfurization tower with an observation port, including a tower body 1, for carrying out the overall desulfurization process. The tower body 1 is composed of several cylindrical sections, which facilitates segmented disassembly and maintenance. A high-pressure flushing system 12 is installed inside the tower body 1, and a sensor module 7 monitors the liquid film thickness in real time. If the scale exceeds 2 mm... If the threshold value is reached (mm), the high-pressure flushing system 12 is activated to flush the tower body 1. An air inlet 9 is provided on the bottom side surface of the tower body 1 to receive flue gas. A sieve plate 11 is provided inside the lower part of the tower body 1 to perform preliminary screening of the flue gas, leaving large particles. A ridge-type tray 4 is provided above the sieve plate 11. The ridge-type tray 4 reduces the risk of tower blockage and increases sulfur capacity. A spray layer 3 is provided above the ridge-type tray 4. After passing through the ridge-type tray 4 and the spray layer 3, the flue gas comes into countercurrent contact with the spray liquid, completing preliminary desulfurization. The spray layer 3 is equipped with spiral atomizing nozzles 6. The spray liquid forms uniform droplets through the spiral atomizing nozzles 6, further absorbing sulfur dioxide in the flue gas. The large-diameter nozzle design also reduces the risk of tower blockage. A demister 5 is provided above the spray layer 3, using a combination structure of swirl blades 14 and a shroud 13. After being purified by the liquid droplets, the flue gas is dehydrated by the demister 5 and discharged in compliance with standards. An exhaust port 10 is set at the top of the tower body 1 above the demister 5. The qualified flue gas is discharged from the exhaust port 10. An observation hole 2 is set below the demister 5. Observation holes 2 are set in areas prone to scaling, such as between spray layers 3, in the sieve plate 11 area, and below the demister 5. Through structural optimization and the setting of observation holes 2 and sensor module 7, it is convenient for operators to directly observe the desulfurization reaction in the tower body 1, realize the visualization and dynamic control of the working conditions in the tower body 1. A quick-opening sealing cover 8 is set on the observation hole 2. The quick-opening sealing cover 8 supports the insertion of detection probes or visual inspection without stopping the machine. A sensor module 7 is set below the observation hole 2. The sensor module 7 integrates an online pH meter, a turbidity sensor and a camera to monitor the liquid film thickness and sulfur particle deposition in real time.
[0023] To better optimize the structure and facilitate segmented disassembly and maintenance, tower body 1 is designed as a segmented structure with a total height of 45 meters, consisting of 30 sections, each 1.5 meters long, with acid-resistant mortar used to seal the joints between the sections.
[0024] To make the structure more compact and efficient, the inner layer of tower body 1 is made of granite anti-corrosion layer, and the outer layer is made of carbon steel layer.
[0025] To improve anti-clogging capabilities, the ridge-type tray 4 is designed as a perforated tray with a 15° tilt angle and 50 mm hole diameter, and is made of 316L stainless steel.
[0026] To enhance the desulfurization effect, spray layer 3 is set to four layers, with a spacing of 4 meters between each layer.
[0027] To enhance the reaction between flue gas and spray liquid for desulfurization, the spiral atomizing nozzle 6 is designed with a double spiral structure, with a nozzle diameter of 12-30 mm, and is made of 316L stainless steel.
[0028] To enhance the observation of areas prone to scaling, several observation holes 2 are provided on the tower body 1. The observation holes 2 are located in areas that are prone to scaling, such as the spray layer 3 area, the sieve plate 11 area, and the demister 5.
[0029] To facilitate observation and increase durability, a viewing window 15 is provided inside the observation hole 2. The viewing window 15 is located inside the quick-opening sealing cover 8. The diameter of the viewing window 15 is 150-300 mm. The viewing window 15 is made of double-layer tempered glass or polycarbonate material.
[0030] To improve detection results, sensor module 7 includes a pH meter, a turbidity sensor, and a high-definition camera.
[0031] To improve the dehydration effect, the demister 5 includes swirl vanes 14 and a cover 13.
[0032] The usage process and working principle of this utility model are as follows: Flue gas enters the bottom of the tower body 1 through the air inlet 9, first passes through the sieve plate 11 to remove large particles, and then passes through the ridge tray 4 and the spray layer 3, where it comes into counter-current contact with the spray liquid from bottom to top to complete the desulfurization process. After that, the purified flue gas is dehydrated by the demister 5 and discharged from the exhaust port 10. This process can be observed in real time through the observation hole 2, and the sensor module 7 is also detecting it in real time. Furthermore, when the sensor module 7 is monitoring the liquid film thickness in real time, if scaling exceeds the 2 mm threshold, the high-pressure flushing system 12 can be activated to flush the inside of the tower body 1.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
