Description

Technical Field

[0001] The utility model mainly relates to the technical field of condensers, in particular to a tube-fin type condenser structure for flue gas cooling. Background Art

[0002] As a compact heat exchange device, the tube-fin condenser is widely used in the refrigeration industry. The tubes and fins of the tube-fin condenser are closely arranged. Compared with other condenser types, the tube-fin condenser occupies less floor space and has higher heat exchange efficiency.

[0003] However, when the existing fins exchange heat with cooling water, only one side of the fin can contact the cooling water, resulting in reduced heat exchange efficiency of the fins. Therefore, a new tube-fin condenser structure for flue gas cooling is needed. Utility Model Content

[0004] The technical solution of the present utility model addresses the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. It mainly provides a tube-fin type condenser structure for flue gas cooling, which is used to solve the technical problem proposed in the above background technology that only one side of the fin can contact the cooling water, resulting in reduced heat exchange efficiency of the fin.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A tube-fin condenser structure for flue gas cooling includes an outer shell, both ends of which are connected and communicated with an air inlet pipe and an exhaust pipe, the left and right sides of the annular surface of the outer shell are connected and communicated with a water inlet pipe and a drain pipe, sealing plates are installed on the left and right sides of the outer shell, the water inlet pipe and the drain pipe extend to the area between the two sealing plates, and circular holes are opened on the opposite sides of the two sealing plates, and condensing elements are installed in the circular holes.

[0007] Preferably, the condensing element includes a connecting pipe, which is installed in the circular hole. A plurality of obliquely arranged hollow fins are connected and communicated on the annular surface of the connecting pipe, and the plurality of fins on the annular surface of the connecting pipe are spirally arranged.

[0008] Preferably, the fins installed on the connecting pipes are arranged alternately with the fins installed on adjacent connecting pipes.

[0009] Preferably, a plurality of intercepting plates are installed in the shell, and a through hole larger than the diameter of the connecting pipe is opened on the side of the intercepting plate, and the connecting pipe is not provided with a fin at the through hole.

[0010] Preferably, a sealing ring is installed in the circular hole, and the sealing ring is sleeved on the annular surface of the connecting pipe.

[0011] Preferably, brackets are installed on both left and right sides of the lower surface of the shell.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By installing multiple spirally inclined fins on the annular surface of the connecting pipe, the cooling water is guided to pass through in a spiral manner, which increases the contact time between the cooling water and the fins in the shell. At the same time, when the cooling water is in spiral motion, the side of the fin facing away from the cooling water can also come into contact with the cooling water, further increasing the heat exchange efficiency.

[0014] 2. By alternately arranging the fins on the annular surfaces of two adjacent connecting tubes, the area occupied by the two connecting tubes is reduced, so that more connecting tubes and fin-composed condensation structures can be installed in the shell, thereby increasing the heat exchange efficiency of the device.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly used by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] Please refer to the attached Figure 1-3 A tube-fin condenser structure for flue gas cooling includes a shell 1, where both ends of the shell 1 are respectively connected to an air inlet pipe 4 and an exhaust pipe 5, and then the left and right sides of the annular surface of the shell 1 are respectively connected to a water inlet pipe 6 and a drain pipe 7, and sealing plates 3 are installed on both sides of the shell 1. The water inlet pipe 6 and the drain pipe 7 extend to the area between the two sealing plates 3. Circular holes are opened on the opposite sides of the two sealing plates 3, and connecting pipes 9 are installed in the circular holes.

[0025] A plurality of obliquely arranged hollow fins 8 are connected and communicated on the annular surface of the connecting pipe 9, and the plurality of fins 8 on the annular surface of the connecting pipe 9 are arranged in a spiral.

[0026] By installing multiple spirally inclined fins 8 on the annular surface of the connecting pipe 9, the cooling water is guided to pass through in a spiral manner, thereby increasing the contact time of the cooling water with the fins 8 in the shell. At the same time, when the cooling water is in spiral motion, the side of the fin 8 facing away from the cooling water can also come into contact with the cooling water, further increasing the heat exchange efficiency.

[0027] The fins 8 on the annular surfaces of two adjacent connecting tubes 9 are arranged alternately, so that the area occupied by the two connecting tubes 9 is reduced, and more condensation structures consisting of connecting tubes 9 and fins 8 can be installed in the shell, thereby increasing the heat exchange efficiency of the device.

[0028] In order to prevent the cooling water from flowing out from between the fins 8 on the connecting pipe 9 as much as possible, a plurality of intercepting plates 2 are installed in the shell 1. The side of the intercepting plate 2 has a through hole 11 larger than the connecting pipe 9, and the connecting pipe 9 is not provided with a fin 8 at the through hole 11.

[0029] In order to ensure the sealing of the connecting pipe 9 in the circular hole, a sealing ring 12 is installed in the circular hole, and the sealing ring 12 is sleeved on the annular surface of the connecting pipe 9.

[0030] In order to support the shell, brackets 10 are installed on both the left and right sides of the lower surface of the shell 1.

[0031] The specific operation process of this utility model is as follows: after the cooling water flows into between the two sealing plates 3 from the water inlet pipe 6, it is intercepted by the interception plate 2, so that the cooling water can only pass through between the multiple fins 8 at the through hole 11, so that the cooling water and the fins 8 are in contact to the greatest extent, and then pass through the through hole 11. When the cooling water passes through the through hole 11, it is separated by the multiple fins 8. Since the multiple fins 8 on the same connecting pipe 9 are arranged in an oblique spiral, the cooling water can also contact the side of the fin 8 away from the cooling water when passing between the two fins 8, thereby increasing the heat conversion efficiency between the cooling water and the fin 8.

[0032] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
