Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically to a finned tube shell-and-tube condenser. Background Technology

[0002] A condenser is a component of a refrigeration system and a type of heat exchanger. It transfers heat from the tubes to the air near the tubes in a rapid manner, converting gas or vapor into liquid. Shell-and-tube condensers are a type of water-cooled condenser.

[0003] Existing tubular condensers use multiple rows of heat exchange tubes arranged in multiple chambers, with the liquid guide plate tilted relative to the horizontal direction. At least at the lower end of the liquid guide plate, there is a liquid flow channel communicating with the outlet; and a gas flow channel is provided to allow refrigerant gas to flow into multiple chambers, thereby improving heat exchange efficiency.

[0004] However, most tubular condensers on the market still have some shortcomings in use: existing tubular condensers usually directly introduce steam into the condenser, the steam is unevenly distributed in the condenser, and the steam is difficult to fully contact the heat exchange tubes at different positions to exchange heat, thus having certain defects in use. Utility Model Content

[0005] The purpose of this utility model is to provide a finned tube shell-and-tube condenser, in which the first and second vent pipes are distributed along the axial and circumferential directions of the condenser shell, respectively, so that steam can be evenly introduced into the interior of the condenser shell, thereby enabling the steam to fully contact the heat exchange tubes at different positions for uniform heat exchange.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a finned tube shell-and-tube condenser, comprising a condenser cylinder, wherein a heat exchange tube is fixedly installed inside the condenser cylinder, and end face support plates are fixedly installed at both ends of the heat exchange tube; a first water storage cylinder is fixedly connected to one end of the condenser cylinder via a flange structure, and a second water storage cylinder is fixedly connected to the other end of the condenser cylinder via a flange structure; an inlet flange pipe and an outlet flange pipe are fixedly connected to the end face of the second water storage cylinder away from the condenser cylinder; a steam dispersion unit is fixedly installed on one outer surface of the condenser cylinder, and the steam dispersion unit includes a first vent pipe fixedly connected to the outer surface of the condenser cylinder.

[0007] As a preferred embodiment of this utility model, heat exchange fins are fixedly arranged inside the condenser cylinder, and the heat exchange fins are staggered between the individual heat exchange tubes.

[0008] As a preferred embodiment of this utility model, a drain flange pipe is fixedly connected to the outer end face of the condenser cylinder, and the steam dispersion unit is arranged on the outside of the condenser cylinder in a corresponding manner to the drain flange pipe.

[0009] As a preferred embodiment of this utility model, the heat exchange tubes are evenly distributed inside the condenser cylinder, and the end support plate has a through hole structure that cooperates with the heat exchange tubes. The heat exchange tubes are connected to the first water storage cylinder and the second water storage cylinder through the through hole structure.

[0010] As a preferred embodiment of this utility model, a partition plate is fixedly installed inside the second water storage cylinder, and the outlet flange pipe and the inlet flange pipe are respectively installed on the upper and lower sides of the partition plate.

[0011] As a preferred embodiment of the present invention, the steam dispersion unit further includes a second vent pipe fixedly disposed on the outer surface of the condenser cylinder, and the second vent pipe is disposed along the axial direction of the condenser cylinder.

[0012] As a preferred embodiment of this utility model, the first ventilation pipe is distributed at equal intervals along the axial direction of the condenser cylinder on the outside of the second ventilation pipe, and one end of the second ventilation pipe is fixedly connected to an air intake pipe that serves as an air intake.

[0013] As a preferred embodiment of the present invention, the steam dispersion unit further includes a connecting pipe fixedly connected to the outer end face of the condenser cylinder. The connecting pipe is evenly distributed around the circumference of the condenser cylinder inside the first ventilation pipe, and the first ventilation pipe is connected to the interior of the condenser cylinder through the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The first and second ventilation pipes are distributed along the axial and circumferential directions of the condenser shell, respectively, so that steam can be evenly introduced into the interior of the condenser shell, thereby enabling the steam to fully contact the heat exchange tubes at different positions for uniform heat exchange.

[0016] 2. The first vent pipe is evenly distributed along the axial direction of the condenser shell to the outside of the second vent pipe, and the connecting pipe is evenly distributed along the circumference of the condenser shell inside the first vent pipe. Steam is introduced into the steam dispersion unit through the inlet pipe. The steam flows along the axial direction of the condenser shell through the second vent pipe, and after being dispersed through the first vent pipe, it flows into the interior of the condenser shell through the connecting pipe. This achieves the effect of evenly introducing steam into the condenser shell. By increasing the uniformity of steam distribution in the condenser shell, the steam can fully contact the heat exchange tubes, thereby enabling the steam to fully exchange heat with the heat exchange tubes and improving the condensation efficiency.

[0017] 3. Heat exchange fins are fixedly installed inside the condenser shell, and the heat exchange fins are staggered between the individual heat exchange tubes. The heat exchange fins increase the contact area between the heat exchange tubes and the steam inside the condenser shell, thereby improving the heat exchange efficiency. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a finned tube shell-and-tube condenser, including a condenser body 1. A heat exchange tube 2 is fixedly installed inside the condenser body 1, and end face support plates 3 are fixedly installed at both ends of the heat exchange tube 2. One end of the condenser body 1 is fixedly connected to a first water storage tank 4 via a flange structure, and the other end of the condenser body 1 is fixedly connected to a second water storage tank 5 via a flange structure. Figure 1 and Figure 2As shown, the heat exchange tubes 2 are evenly distributed inside the condenser cylinder 1, and the end support plate 3 has through holes that cooperate with the heat exchange tubes 2. The heat exchange tubes 2 are interconnected with the first water storage cylinder 4 and the second water storage cylinder 5 through these through holes, allowing cooling water to flow evenly through the interior of the condenser cylinder 1. Figure 2 and Figure 3 As shown, the second water storage tank 5 is fixedly connected to an inlet flange pipe 7 and an outlet flange pipe 8 on the end face away from the condenser tank 1. A partition plate 6 is fixedly installed inside the second water storage tank 5, and the outlet flange pipe 8 and the inlet flange pipe 7 are respectively located on the upper and lower sides of the partition plate 6. Cooling water is input into the second water storage tank 5 through the inlet flange pipe 7. After the cooling water flows into the first water storage tank 4 through the heat exchange pipe 2, it flows back into the second water storage tank 5 through the heat exchange pipe 2 and finally is discharged through the outlet flange pipe 8, which plays the role of cooling the steam inside the condenser tank 1.

[0026] Specific examples Figure 4 and Figure 5 As shown, heat exchange fins 11 are fixedly installed inside the condenser shell 1, and the heat exchange fins 11 are staggered between the individual heat exchange tubes 2. The heat exchange fins 11 increase the contact area between the heat exchange tubes 2 and the steam inside the condenser shell 1, thereby improving the heat exchange efficiency. A drain flange pipe 12 is fixedly connected to the outer end face of the condenser shell 1. The steam dispersion unit 900 and the drain flange pipe 12 are respectively arranged on the outside of the condenser shell 1. The liquid condensed by the finned tube shell condenser is discharged through the drain flange pipe 12.

[0027] Specific examples Figure 1 and Figure 4As shown, a steam dispersion unit 900 is fixedly installed on one outer surface of the condenser cylinder 1. The steam dispersion unit 900 includes a first vent pipe 901 fixedly connected to the outer surface of the condenser cylinder 1, and a second vent pipe 902 fixedly installed on the outer surface of the condenser cylinder 1. The second vent pipe 902 is arranged along the axial direction of the condenser cylinder 1. The first vent pipes 901 are evenly distributed along the axial direction of the condenser cylinder 1 outside the second vent pipe 902. One end of the second vent pipe 902 is fixedly connected to an air inlet pipe 10, which serves as an air inlet. Steam to be condensed is introduced into the steam dispersion unit 900 through the air inlet pipe 10. The steam dispersion unit 900 also includes a connecting pipe 903 fixedly connected to the outer end face of the condenser cylinder 1. The connecting pipe 903 is evenly distributed along the circumference of the condenser cylinder 1 inside the first ventilation pipe 901, and the first ventilation pipe 901 is connected to the inside of the condenser cylinder 1 through the connecting pipe 903. Steam flows along the axial direction of the condenser cylinder 1 through the second ventilation pipe 902, and after being dispersed through the first ventilation pipe 901, it flows into the inside of the condenser cylinder 1 through the connecting pipe 903. This serves to make the steam evenly introduced into the condenser cylinder 1, improve the uniformity of the steam in the condenser cylinder 1, and enable the steam to fully exchange heat with the cooling water in the heat exchange tube 2, thereby improving the condensation efficiency.

[0028] The working principle of this utility model:

[0029] When using this finned tube shell-and-tube condenser, steam is first introduced into the steam dispersion unit 900 through the inlet pipe 10, specifically as follows: Figure 1 and Figure 4 As shown, since the first vent pipe 901 is evenly distributed along the axial direction of the condenser cylinder 1 on the outside of the second vent pipe 902, and the connecting pipe 903 is evenly distributed along the circumference of the condenser cylinder 1 inside the first vent pipe 901, steam flows along the axial direction of the condenser cylinder 1 through the second vent pipe 902, and after being dispersed through the first vent pipe 901, it flows into the interior of the condenser cylinder 1 through the connecting pipe 903. This serves to ensure that steam is evenly introduced into the condenser cylinder 1, improve the uniformity of steam in the condenser cylinder 1, and ensure that the steam is in full contact with the heat exchange tube 2, so that the steam and the cooling water in the heat exchange tube 2 can exchange heat fully, thereby improving the condensation efficiency.

[0030] The heat exchange fins 11 are staggered between the individual heat exchange tubes 2 to increase the contact area with steam and improve the heat exchange efficiency. The condensed liquid is discharged from the condenser shell 1 through the drain flange pipe 12.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
