[0002] During the oxy-fuel combustion process, due to the improvement of combustion efficiency, the amount of flue gas generated will also increase accordingly. Therefore, the flue gas collection water jacket needs to have good sealing performance and high temperature resistance to ensure that the flue gas does not leak into the environment.

[0003] The water jacket seal is formed by welding two water jacket sealing structures. Sealing baffles are installed around the main body part of the water jacket sealing structure by means of welding.

Detailed implementation manners

[0023] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementations disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manner.

[0025] During the oxy-fuel combustion process, due to the improvement of combustion efficiency, the amount of flue gas generated will also increase accordingly; therefore, the flue gas collection water jacket needs to have good sealing performance and high-temperature resistance to ensure that the flue gas does not leak into the environment.

[0026] The water jacket seal is formed by welding two water jacket seal structures. Sealing baffles are installed around the main body part of the water jacket seal structure by means of welding. The area of the welding structure needs to be ensured to be continuous and complete to ensure the sealing performance and strength of the overall structure.

[0027] However, the traditional water jacket seal structure requires at least four baffles to be welded, and the baffles also need to be welded and sealed; at least 8 welds are required for a set of water jacket seal structures. The welding construction requirements are relatively high, and the sealing performance and strength of the structure after welding are greatly affected by the quality of the welding structure. As the fully welded water jacket seal structure is used for a longer time, its use effect deteriorates and its service life is reduced.

[0028] To solve the above problems, refer to the attached Figure 1 - attached Figure 3, a water jacket sealing structure, including a sealing main body 100. On the upper ends of both the left and right sides of the sealing main body 100, first sealing baffles 200 are provided. On the upper ends of both the front and back sides of the sealing main body 100, second sealing baffles 300 are provided. The two first sealing baffles 200, the two second sealing baffles 300, and the sealing main body 100 enclose to form a water jacket sealing structure. Two relatively arranged water jacket sealing structures can form a chamber for fluid to pass through inside.

[0029] The two first sealing baffles 200 and the sealing main body 100 are integrally formed. Between the two second sealing baffles 300 and the sealing main body 100, they are formed by welding. Between the second sealing baffle 300 and the sealing main body 100, they are fixed through a first welding structure 320. On both sides of the second sealing baffle 300, they are respectively fixed to the two first sealing baffles 200 through second welding structures 310. Both the second welding structure 310 and the first welding structure 320 are formed by welding technology. After welding and fixing, the bottom of the water jacket sealing structure is in a relatively closed state, avoiding fluid leakage.

[0030] Through the above structural design, by bending the first sealing baffles 200 on both sides, welding and fixing are not required, reducing the length that needs to be welded and fixed. While improving the sealing performance of the overall structure, the welding difficulty is reduced, and the manufacturing efficiency of the water jacket sealing structure is greatly improved. This type of water jacket sealing structure has high strength, better effect, and longer service life during subsequent use.

[0031] Preferably, the left and right sides of the sealing main body 100 are set as long sides, and the front and back sides of the sealing main body 100 are set as short sides. Through the above-set structure, the length of the welding structure can be further reduced, the sealing effect at the first sealing baffle 200 can be ensured, the welding manufacturing difficulty is reduced, and the welding manufacturing efficiency is improved.

[0032] Furthermore, a strengthening structure 400 is installed at the adjacent position between the first sealing baffle 200 and the second sealing baffle 300. Through the strengthening structure 400, the first sealing baffle 200 and the second sealing baffle 300 can be welded and fixed, which can ensure the stability of the first sealing baffle 200 and the second sealing baffle 300 from the inside, further enhancing the strength of the overall structure, enhancing the sealing performance and service life.

[0033] Here, the first side of the strengthening structure 400 is fixedly connected to the second sealing baffle 300 through a third welding structure 411, and the second side of the strengthening structure 400 is fixedly connected to the first sealing baffle 200 through a fourth welding structure 412. The way of welding and fixing is simple and convenient, and the four strengthening structures 400 can be quickly installed at the predetermined corners, improving the processing and manufacturing efficiency.

[0034] Preferably, the third welding structure 411 is arranged on the side far from the second welding structure 310, and the fourth welding structure 412 is arranged on the side close to the second welding structure 310. Through the above structural design, while reducing the volume of the space on one side of the first sealing baffle 200, the third welding structure 411 is controlled to be located in the middle position close to the second sealing baffle 300, which can more effectively utilize the first sealing baffle 200 to fix the second sealing baffle 300, and further improve the strength and sealing effect of the overall structure.

[0035] A positioning hole 500 is opened at the upper end of the strengthening structure 400. By providing the positioning hole 500, the two water jacket sealing structures can be positioned, which is convenient for the subsequent processing and manufacturing of the water jacket seal.

[0036] Finally, it should also be noted that the sealing main body 100 and the first sealing baffle 200 here can be bent and formed by existing hydraulic equipment; for water jacket sealing structures with some special requirements, they can also be manufactured by casting.

[0037] Refer to the attached Figure 4 - attached Figure 5 , a water jacket seal, including two water jacket sealing structures with the above-mentioned positioning holes 500, and at least including two positioning pins 600. The two water jacket sealing structures are arranged oppositely, and the positioning pins 600 are located in the corresponding positioning holes 500. By arranging the positioning pins 600 between the positioning holes 500 of the two water jacket sealing structures, the two positioning holes 500 can be limited and fixed by the positioning pins 600, ensuring the accurate positioning of the two water jacket sealing structures, and ensuring the accurate and stable welding positioning of the subsequent two water jacket sealing structures.

[0038] The peripheries of adjacent two water jacket seal welds are also fixed by welding. A long welding structure 2001 and a short welding structure 3001 are welded around the water jacket seal, ensuring the stable fixation of the two water jacket sealing structures on both sides and the sealing performance of the overall structure.

[0039] Preferably, the inner wall of the positioning hole 500 is frustum-shaped, and the outer shapes of both ends of the positioning pin 600 are adapted to the inner wall of the positioning hole 500. By arranging the above structure, the positioning requirements of the two water jacket sealing structures can be reduced, and the two water jacket sealing structures can be quickly positioned to the predetermined state, further improving the manufacturing efficiency of the water jacket seal.

[0040] After the two water jacket sealing structures are limited and fixed by the positioning pins 600, they can still be repositioned by welding positioning pieces 700 on the outside. By welding a plurality of positioning pieces 700, the two water jacket sealing structures can be prevented from shaking during the circumferential welding process, ensuring the stability of the overall structure.

[0041] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
