[0002] Flue gas is a gas mixture produced during industrial production, energy combustion and other chemical reactions. It usually includes components such as carbon dioxide, oxygen, nitrogen, trace toxic gases, particulate matter and water vapor. Water-containing flue gas refers to flue gas containing a large amount of water vapor, which is common in industrial fields such as chemical industry, power generation, and smelting. Water vapor may cause a variety of problems in flue gas, including increased condensation and corrosion on the inner wall of the pipe, and affecting the uniformity of flue gas emissions. Therefore, the effective treatment of water-containing flue gas is particularly important, which not only helps the efficiency and quality of industrial production, but also reduces the impact on the environment and equipment.

[0003] The treatment of water-containing flue gas usually includes a heating step. During the heating treatment of water-containing flue gas, the heating components and their removal positions face the potential problem of corrosion. Moisture may combine with other components in the flue gas to form corrosive substances, which will have a corrosive effect on the heating components and their removal positions. Long-term accumulation may cause component damage and reduce the life of the equipment. In addition, water vapor and other components generated during the heating process may accumulate at the removal position, increasing the difficulty of cleaning and maintaining the equipment. This corrosion and accumulation phenomenon not only affects the heating efficiency, but may also cause problems such as blockage and leakage in the pipeline or equipment. Therefore, it is crucial for industrial production and environmental protection to design a heating device that can effectively treat water-containing flue gas, reduce the effects of corrosion and accumulation, and is easy to maintain.

[0030] See also Figure 1-5 As shown, the utility model provides a technical solution of a water-containing flue gas heating treatment device: a water-containing flue gas heating treatment device, comprising a pipe body 1, a plurality of heating mechanisms 2 are detachably installed inside the pipe body 1, and a plurality of side door mechanisms 3 are arranged on the side of the pipe body 1 for facilitating the removal of the heating mechanisms 2;

[0031] The heating mechanism 2 includes a first recessed portion 201, an annular outer frame 202, and a honeycomb heating plate 206. The first recessed portion 201 is provided on the inner side of the side door mechanism 3 and the tube body 1. The annular outer frame 202 is detachably mounted inside the tube body 1. A first protrusion 203 matching the shape of the first recessed portion 201 is designed on the outer side of the annular outer frame 202. A first guide portion 204 is designed at the air inlet of the annular outer frame 202. A second guide portion 205 is designed at the air outlet of the annular outer frame 202. The honeycomb heating plate 206 is provided on the outer side of the annular outer frame 202. Plate 206 is installed on the inner side of the annular outer frame 202. During operation, the water-containing flue gas will first enter the inner side of the honeycomb heating plate 206 for heating under the guidance of the first guide portion 204 of the annular outer frame 202, and then leave under the guidance of the second guide portion 205 of the annular outer frame 202, and enter the interior of the second honeycomb heating plate 206 for heating. During this process, the water-containing flue gas is in contact with the side door mechanism 3 for a short time, which greatly reduces the annular impact on the side door mechanism 3, thereby improving the durability of the entire device.

[0032] The side door mechanism 3 includes a plurality of side doors 301 and a hoop 303. The side doors 301 are rotatably connected to the upper part of the tube body 1. The first recessed portion 201 is located on the inner side of the side doors 301. A gap 302 is reserved between the side doors 301. The hoop 303 is arranged on the outer side of the tube body 1 and is located at the gap 302 between the side doors 301. When the heating mechanism 2 needs to be maintained, the hoop 303 needs to be loosened, and then the side door 301 is opened to take out the heating mechanism 2 for maintenance. After the maintenance is completed, the first protrusion 203 of the annular outer frame 202 needs to be aligned with the first recessed portion 201 of the tube body 1 and then the side door 301 is closed and the hoop 303 is tightened. At this time, the side door 301 and the first recessed portion 201 on the inner side of the tube body 1 will position the annular outer frame 202 to ensure that the position will not change during the process.

[0033] A second protrusion 4 is provided on the tube body 1, and a second recessed portion 5 matching the second protrusion 4 is provided on the side door 301. Through the cooperation of the second protrusion 4 and the second recessed portion 5, the sealing between the tube body 1 and the side door 301 can be enhanced, and the water-containing smoke can be effectively prevented from escaping from the gap during the heating process. In the specific implementation process, a high-temperature resistant sealing ring can also be provided on the outer part of the second protrusion 4 and the second recessed portion 5 to further improve the sealing effect.

[0034] The annular outer frame 202 is made of ceramic. This design can ensure that it will not deform or be damaged in a high temperature environment. In addition, the ceramic material also has good corrosion resistance, so that it is not affected by the acidity, alkalinity or other components of the flue gas during the process, which helps to extend the service life of the heating device.

[0035] The inner wall of the tube body 1 is provided with a plurality of third guide portions 6. In the specific implementation process, the third guide portion 6 can be set at the front end of the contact portion between each side door 301 and the tube body 1. This design can guide the water-containing flue gas to flow directly to the honeycomb heating plate 206, thereby reducing the residence time of the flue gas in the contact portion between the side door 301 and the tube body 1, avoiding corrosion of the contact portion between the side door 301 and the tube body 1, and extending the life of the equipment.

[0036] The outer surfaces of the tube body 1 and the side door 301 are both provided with positioning side plates 7. The positioning side plates 7 can ensure that the hoop 303 will not be displaced after being fixed, and ensure that the hoop 303 can remain in place stably during daily operation or when affected by external forces, thereby preventing the side door 301 from being accidentally opened during normal operation.

[0037] The working principle of the utility model is as follows:

[0038] During the operation of the water-containing flue gas heating treatment device of the present embodiment, the water-containing flue gas first enters the inner side of the honeycomb heating plate 206 under the guidance of the first guide portion 204 of the annular outer frame 202 for heating, and then leaves under the guidance of the second guide portion 205 of the annular outer frame 202 and enters the inner side of the second honeycomb heating plate 206 for heating. This process shortens the contact time between the water-containing flue gas and the connection between the side door 301 and the pipe body 1, thereby improving the durability of the device. When maintenance is required, the hoop 303 is loosened, and then the side door 301 is opened, and the annular outer frame 202 can be taken out for maintenance and cleaned. After maintenance, the first raised portion 205 of the annular outer frame 202 is 03 is aligned with the first recessed portion 201 of the tube body 1 and then the side door 301 is closed and the hoop 303 is tightened to achieve the reinstallation of the annular outer frame 202. At this time, the side door 301 and the first recessed portion 201 on the inner side of the tube body 1 will play a positioning role for the annular outer frame 202 to ensure the stable operation of the device. The water-containing flue gas heating treatment device can effectively guide the flow of water-containing flue gas, reduce the contact with the side door mechanism 3, reduce the risk of corrosion, and extend the life of the equipment. On the other hand, by setting the side door 301 and the hoop 303, it is convenient for technical personnel to access the inside of the tube body 1 for maintenance, and by locking the side door 301, the escape of water-containing flue gas can be prevented, thereby improving the sealing of the system.
