Description

Technical Field

[0001] The utility model relates to the technical field of economizers, in particular to a high-efficiency economizer structure. Background Art

[0002] The economizer usually includes a frame, in which a number of parallel pipes are welded, and a number of elbows are welded on the frame to connect the pipes. The parallel pipes extend out of the frame to connect the header. There are too many welded parts, and the economizer installation efficiency is low. At the same time, the fluid will lose more heat when it is collected or dispersed through the external pipes and headers, resulting in a decrease in heat exchange efficiency.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0025] Example:

[0026] This embodiment discloses a high-efficiency economizer structure.

[0027] Figure 1 This is an axonometric diagram of a high-efficiency economizer structure of the utility model. Figure 1 As shown, the economizer structure includes a frame 1, a first shell 2 and a second shell 3.

[0028] The frame 1 includes a tube 11, and the tube 11 is connected to the frame 1. Exemplarily, the frame 1 has a vertical through hole 12, and high-temperature flue gas flows through the through hole 12. The tube 11 is horizontally arranged in the frame 1. Figure 2 This is a side view of the frame structure of a high-efficiency economizer structure of the utility model. Figure 2 As shown, preferably, the tubes 11 are staggered in the through holes 12. Since the arrangement of the first shell 2 and the second shell 3 frees the tubes 11 from restrictions on their positions, the tubes 11 can be staggered, and when smoke passes through the frame 1, turbulence is generated when the smoke passes through the staggered tubes 11, thereby improving the heat exchange efficiency with the tubes 11.

[0029] Figure 3 This is a cross-sectional view of a high-efficiency economizer structure of the utility model. Figure 3As shown, the first shell 2 is a hollow structure, which is arranged on the first side of the frame 1, and includes a first chamber 21, a second chamber 22, a water inlet pipe 23 and a water outlet pipe 24. The first chamber 21 is opened at the lower end of the first shell 2, and is connected to the first end of a part of the tube body 11. The second chamber 22 is opened at the upper end of the first shell 2, and is connected to the first end of another part of the tube body 11, and the second chamber 22 is not connected to the first chamber 21. The water inlet pipe 23 is connected to the first chamber 21, and the water outlet pipe 24 is connected to the second chamber 22. Exemplarily, a partition 25 is arranged in the first shell 2, and the first chamber 21 and the second chamber 22 are separated from the first shell 2 by the partition 25. Figure 4 This is an axonometric view of a high-efficiency economizer structure of the utility model, in which the first shell is composed of two shells. Figure 4 As shown, in other embodiments of the present invention, the first shell portion 2 may also be two independent shells 26 , which are welded to the first side of the frame 1 , and the first chamber 21 and the second chamber 22 are respectively defined in the two shells 26 .

[0030] like Figure 3 As shown, the second shell 3 is a hollow structure, which is arranged on the second side of the frame 1 and communicates with the second end of the tube 11. Exemplarily, a third chamber 31 is provided in the second shell 3. The first shell 2 and the second shell 3 are connected to the frame 1 by welding.

[0031] like Figure 1 and Figure 3 As shown, the water inlet pipe 23 is arranged at the lower end of the side of the first shell part 2, and the water outlet pipe 24 is arranged at the upper end of the side of the first shell part 2, so that when the fluid enters, it can fill all the pipes under the action of gravity.

[0032] In this embodiment, a first shell 2 and a second shell 3 are arranged on both sides of the frame 1, and the first shell 2 and the second shell 3 are directly connected to the tube body 11, so that the fluid can be directly collected or dispersed, reducing the setting of extended pipes and elbows, and improving the installation efficiency of the economizer. In the process of collection and dispersion, the fluid is always in contact with the frame 1 for heat exchange, which reduces heat loss and improves heat exchange efficiency.

[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
