Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a uniformly dispersed structure of a heat exchanger. Background Art

[0002] In the biopharmaceutical industry, there is often a need to heat or cool materials. Heat exchange calculations are based on the physical parameters of the materials requiring temperature control, and the calculations for heat exchangers with normal flow rates are relatively simple. However, special operating conditions may occur, such as extremely low flow rates, low thermal conductivity of materials, or large temperature differences between materials. The heat exchanger selected based on common experience may differ significantly from the actual operating conditions. Specifically, the heat exchanger may be too large, or the material flow rate may be too low to completely fill the heat exchanger tube bundle or be evenly dispersed within the tube bundle, resulting in insufficient heat exchange and a significant waste of resources. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides a heat exchanger uniform dispersion structure, which overcomes the shortcomings of the existing technology and has a reasonable design, so that the material can be evenly distributed in the heat exchanger tube bundle after entering the heat exchanger at the heat exchanger inlet end, making full use of the space inside the tube and improving the heat transfer efficiency.

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A heat exchanger uniform dispersion structure includes an interface connecting pipe that passes through from top to bottom, a blind plate fixedly installed on the upper end of the interface connecting pipe, a head fixedly connected to the bottom of the interface connecting pipe, a head joint provided below the head, a distributor connecting pipe fixedly installed in the middle of the blind plate, the lower end of the distributor connecting pipe passes through the blind plate and the interface connecting pipe and is fixedly connected to a dispersion bin, the dispersion bin is located in the inner cavity of the head, and a plurality of small holes are evenly opened on the side surface and lower surface of the dispersion bin.

[0006] Preferably, a sealing ring is provided between the lower surface of the blind plate and the mounting flange at the upper end of the interface connecting pipe.

[0007] Preferably, a quick-release connector is fixedly installed on the upper end of the distributor connecting pipe, and the quick-release connector is connected to the feed pipe.

[0008] Preferably, the side surface of the interface connection tube is connected to one end of the cleaning interface tube, and the other end of the cleaning interface tube is fixedly mounted with a cleaning pipeline joint.

[0009] The utility model provides a uniform dispersion structure for a heat exchanger. It has the following beneficial effects: the material first enters the distributor connecting pipe through the inlet end thereof, then falls along the distributor connecting pipe into the dispersion bin, and is then squeezed out from the small holes on the lower and side surfaces of the dispersion bin under the pressure of the system pipeline, thereby being uniformly dispersed into the inner cavity of the head. Subsequently, the material can be evenly distributed in the heat exchanger tube bundle after entering the heat exchanger at the inlet end, thereby making full use of the space inside the tube, increasing turbulence, and improving heat transfer efficiency, thereby effectively ensuring that sufficient heat exchange can be achieved inside each heat exchange tube.

[0015] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0016] Example 1, as Figure 1-2 As shown, a heat exchanger uniform dispersion structure includes an interface connecting pipe 1 that passes through from top to bottom, a blind plate 2 is fixedly installed on the upper end of the interface connecting pipe 1, a head 3 is fixedly connected to the bottom of the interface connecting pipe 1, a head joint 4 is provided below the head 3, a distributor connecting pipe 5 is fixedly installed in the middle of the blind plate 2, the lower end of the distributor connecting pipe 5 passes through the blind plate 2 and the interface connecting pipe 1 and is fixedly connected to a dispersion bin 6, the dispersion bin 6 is located in the inner cavity of the head 3, and a plurality of small holes 7 are evenly opened on the side surface and the lower surface of the dispersion bin 6.

[0017] Working principle:

[0018] When the temperature control condition is in progress, the head joint 4 below the head 3 is first connected to the inlet end of the heat exchanger, and then the inlet end of the distributor connecting pipe 5 is connected to the feed pipe to complete the connection of the device; thereafter, during operation, the material first enters the distributor connecting pipe 5 through the inlet end of the distributor connecting pipe 5, and then falls along the distributor connecting pipe 5 into the dispersion bin 6, and then is squeezed out from the small holes 7 on the lower surface and side surface of the dispersion bin 6 under the action of the pressure of the system pipeline, so as to be evenly dispersed into the inner cavity of the head 3, and then the material can be evenly distributed in the heat exchanger tube bundle after entering the heat exchanger at the inlet end of the heat exchanger, so that the space inside the tube can be fully utilized, the turbulence is increased, and the heat transfer efficiency is improved, thereby effectively ensuring that sufficient heat exchange can be carried out inside each heat exchange tube.

[0019] Example 2, as a further preferred embodiment of Example 1, a sealing ring 9 is fixedly mounted on the flange on the upper surface of the interface connecting pipe 1. The sealing ring 9 is pressed between the lower surface of the blind plate 2 and the mounting flange on the upper end of the interface connecting pipe 1. The provision of the sealing ring 9 ensures a sealing effect between the blind plate 2 and the interface connecting pipe 1.

[0020] In the third embodiment, as a further preferred embodiment of the first embodiment, a quick-release connector 10 is fixedly mounted on the inlet end of the distributor connecting pipe 5, and the quick-release connector 10 is connected to the feed pipe. Thus, when the inlet end of the distributor connecting pipe 5 is connected to the feed pipe, the quick-release connector 10 can be used to quickly connect the inlet end of the feed pipe to the outlet end.

[0021] In the fourth embodiment, as a further preferred embodiment of the first embodiment, the side of the interface connecting pipe 1 is connected to one end of the cleaning interface pipe 8, and the other end of the cleaning interface pipe 8 is fixedly mounted with a cleaning pipe joint 11. By providing a cleaning interface pipe 8 on the side of the interface connecting pipe 1, the cleaning pipe joint 11 of the cleaning interface pipe 8 can be connected to an external cleaning pipeline. Thus, cleaning water can be introduced from the inner cavity of the interface connecting pipe 1 into the interior of the heat exchanger through the cleaning interface pipe 8, thereby achieving the cleaning effect on the internal tube bundle of the heat exchanger.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents.
