Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a novel tubular heat exchanger. Background Technology

[0002] Tubular heat exchangers are the most typical type of indirect heat exchanger. They have a long history of industrial application and still dominate the category of all heat exchangers. Tubular heat exchangers mainly consist of a shell, tube bundle, tube sheet, and end caps. The shell is mostly circular and contains parallel tube bundles. The two ends of the tube bundles are fixed to the tube sheet. The two fluids that exchange heat in a tubular heat exchanger flow in two directions: one flows inside the tubes, and its path is called the tube side; the other flows outside the tubes, and its path is called the shell side. The wall surface of the tube bundle is the heat transfer surface.

[0003] Existing tubular heat exchangers, due to their large size, are difficult to clean over long periods of use. Improper cleaning may lead to dirt or dust on the surface of the device, causing corrosion and reducing its service life. In addition, impurities may accumulate inside the heat exchanger during prolonged use, which may reach the outlet and reduce efficiency by half, thus affecting work efficiency.

[0004] To address the aforementioned issues, the utility model patent with authorization announcement number CN214582650U discloses a novel tubular heat exchanger. This device, through optimization of the novel tubular heat exchanger body, achieves an easy-to-clean effect, preventing situations where some parts of the device are difficult to clean, and where dirt and dust on the surface may corrode the device surface and reduce its service life if it is not cleaned for a long time.

[0005] However, in actual use, when the heat exchanger body is damaged or needs cleaning, the entire device cannot be used normally, reducing its practicality and failing to meet usage requirements. Utility Model Content

[0006] The purpose of this invention is to provide a novel tubular heat exchanger to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel tubular heat exchanger includes: a heat exchange box, wherein a partition plate is installed inside the heat exchange box, dividing the interior of the heat exchange box into a rear heat exchange chamber one and a front heat exchange chamber two, and a box cover is installed on the upper end of the heat exchange box corresponding to the positions of heat exchange chamber one and heat exchange chamber two; a pair of filtration mechanisms, respectively installed in heat exchange chamber one and heat exchange chamber two, for filtering the liquid being heat exchanged; a first heat exchange mechanism, installed in heat exchange chamber one, for heating the liquid in heat exchange chamber one; and a second heat exchange mechanism, installed in heat exchange chamber two, for heating the liquid in heat exchange chamber two.

[0009] As a preferred embodiment, a liquid inlet tee is installed on the left side of the heat exchange box. The first liquid outlet pipe of the liquid inlet tee is connected to the first heat exchange chamber, and the second liquid outlet pipe of the liquid inlet tee is connected to the second heat exchange chamber. A first liquid inlet valve is installed on the first liquid outlet pipe of the liquid inlet tee, and a second liquid inlet valve is installed on the second liquid outlet pipe of the liquid inlet tee.

[0010] As a preferred embodiment, a liquid outlet tee is installed on the right side of the heat exchange box. The first liquid outlet tee is connected to the first heat exchange chamber, and the second liquid outlet tee is connected to the second heat exchange chamber. A first liquid outlet valve is installed on the first liquid outlet tee, and a second liquid outlet valve is installed on the second liquid outlet tee.

[0011] As a preferred embodiment, the filtration mechanism includes a filter frame installed in heat exchange chamber one and heat exchange chamber two, and the filter frame has a slot for inserting a filter plate.

[0012] As a preferred embodiment, the filter plate is provided with grooves.

[0013] As a preferred embodiment, both heat exchange mechanism one and heat exchange mechanism two are composed of the same heat exchange components. Each heat exchange component includes a top plate and a bottom plate. Multiple sets of guide plates one are installed on the top plate, and multiple sets of guide plates two are installed on the bottom plate. The guide plates one and two are staggered. Multiple sets of electric heating tubes are inserted between the guide plates one and two. The top plate is installed at the lower end of the corresponding box cover.

[0014] As a preferred embodiment, a sealing ring is also provided between the box cover and the heat exchange box.

[0015] Compared with existing technologies, the advantages of this invention are as follows: By setting a partition plate to divide the heat exchange box into heat exchange chamber two and heat exchange chamber one on the front and rear sides, when cleaning and maintenance are required in heat exchange chamber one, heat exchange mechanism two in heat exchange chamber two can still operate normally, and vice versa. This ensures the normal operation of the device and prevents the entire device from malfunctioning due to localized cleaning or damage to some heat exchange components, thus better meeting usage requirements. This invention has a simple structure; when cleaning is required in any heat exchange chamber or any heat exchange component is damaged, the heat exchange components in the other heat exchange chambers can still continue to operate normally, ensuring the normal use of the device and better meeting usage requirements.

Detailed Implementation

[0021] 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.

[0022] Example: Please refer to Figures 1-4A novel tubular heat exchanger includes: a heat exchange chamber 1, wherein a partition plate 14 is installed inside the heat exchange chamber 1, dividing the interior of the heat exchange chamber 1 into a rear heat exchange chamber 12 and a front heat exchange chamber 2 13; a cover 11 is installed on the upper end of the heat exchange chamber 1 at positions corresponding to heat exchange chamber 12 and heat exchange chamber 2 13, and a sealing ring 15 is provided between the cover 11 and the heat exchange chamber 1; a filter mechanism 6, consisting of a pair, is installed in heat exchange chamber 12 and heat exchange chamber 2 13 respectively, for filtering the liquid undergoing heat exchange; a heat exchange mechanism 4, installed in heat exchange chamber 12, for heating the liquid in heat exchange chamber 12; and a heat exchange mechanism 5, installed in heat exchange chamber 2 13, for heating the liquid in heat exchange chamber 2 13.

[0023] The working principle of this utility model is as follows: By setting a partition plate 14, the heat exchange box 1 is divided into heat exchange chamber 2 13 and heat exchange chamber 12 on the front and rear sides. When it is necessary to clean and maintain the heat exchange chamber 12, the heat exchange mechanism 2 5 in the heat exchange chamber 2 13 can work normally. When it is necessary to clean and maintain the heat exchange chamber 2 13, the heat exchange mechanism 1 4 in the heat exchange chamber 12 can work normally, thereby ensuring the normal operation of the device. The device will not fail to work normally due to local cleaning work or damage to some heat exchange components, thus better meeting the usage requirements.

[0024] As a further embodiment, a liquid inlet tee pipe 2 is installed on the left side of the heat exchange box 1. The first liquid outlet pipe of the liquid inlet tee pipe 2 is connected to the first heat exchange chamber 12, and the second liquid outlet pipe of the liquid inlet tee pipe 2 is connected to the second heat exchange chamber 13. A liquid inlet valve 21 is installed on the first liquid outlet pipe of the liquid inlet tee pipe 2, and a liquid inlet valve 22 is installed on the second liquid outlet pipe of the liquid inlet tee pipe 2.

[0025] A liquid outlet tee pipe 3 is installed on the right side of the heat exchange box 1. The first liquid outlet pipe of the liquid outlet tee pipe 3 is connected to the first heat exchange chamber 12, and the second liquid outlet pipe of the liquid outlet tee pipe 3 is connected to the second heat exchange chamber 13. A liquid outlet valve 31 is installed on the first liquid outlet pipe of the liquid outlet tee pipe 3, and a liquid outlet valve 32 is installed on the second liquid outlet pipe of the liquid outlet tee pipe 3.

[0026] When heat exchange chamber 12 is needed, open the inlet valve 21 on the inlet tee pipe 2 and close the inlet valve 2. At the same time, open the outlet valve 31 on the outlet tee pipe 3 and close the outlet valve 32. The heat exchange mechanism 4 in the heat exchange chamber 12 can then be used to exchange heat with the liquid.

[0027] When heat exchange chamber 213 is needed, open the inlet valve 2 on the inlet tee pipe 2 and close the inlet valve 1 21. At the same time, open the outlet valve 2 32 on the outlet tee pipe 3 and close the outlet valve 1 31. The heat exchange mechanism 2 5 in the heat exchange chamber 213 can then perform heat exchange on the liquid.

[0028] As a further embodiment, the filtration mechanism 6 includes a filter frame 61 installed in heat exchange chamber one 12 and heat exchange chamber two 13. The filter frame 61 has a slot for inserting a filter plate 62, and the filter plate 62 has a groove 63. The groove 63 facilitates the installation and removal of the filter plate 62.

[0029] By setting up the filtration mechanism 6, the liquid to be heat exchanged can be filtered, which can effectively prevent impurities from adhering to the heat exchange components and affecting subsequent use.

[0030] As a further embodiment, both the heat exchange mechanism 4 and the heat exchange mechanism 5 are composed of the same heat exchange components. The heat exchange components include a top plate 51 and a bottom plate 53. Multiple sets of guide plates 52 are installed on the top plate 51, and multiple sets of guide plates 54 are installed on the bottom plate 53. The guide plates 52 and 54 are staggered. Multiple sets of electric heating tubes 55 are inserted between the guide plates 52 and 54. The top plate 51 is installed at the lower end of the corresponding cover 11.

[0031] The working principle of the heat exchange component is as follows: by setting multiple sets of staggered flow guide plates 52 and 54, an S-shaped flow channel is formed in the heat exchange chamber 12 (heat exchange chamber 13), which prolongs the time of the heat exchange liquid in the heat exchange box 1. Then, the liquid is heated by the electric heating tube 55, thereby completing the heat exchange of the body fluid.
