Abstract
Description
Technical Field
[0001] This utility model relates to the field of tubular reactor technology, and in particular to a heat exchange device for the outlet of a tubular reactor. Background Technology
[0002] Tubular reactors are commonly used in continuous reaction processes, particularly suitable for gas, liquid, or two-phase reactions. To better control the temperature changes of the materials in the reactor and ensure the stability of the reaction process and the controllability of the reaction rate, a heat exchange device is usually installed at the outlet. There are many types of heat exchange devices, and plate heat exchangers are one of the most frequently used.
[0003] When a plate heat exchanger is used in conjunction with the outlet of a tubular reactor, the outlet of the tubular reactor is connected to the inlet of the plate reactor. This allows the hot and cold fluids to enter the heat exchanger from different inlets. The two fluids at different temperatures exchange heat through a heat transfer medium (i.e., metal plates), achieving the effect of material temperature control. However, in actual use, it has been found that the heat exchange plates of the plate heat exchanger are thin and exposed, lacking corresponding protective measures. This leads to a risk of contact and collision with other objects in the processing and use environment, resulting in damage to the heat exchange plates and fluid leakage, posing a certain safety hazard. Utility Model Content
[0004] The technical problem this invention aims to solve is that after connecting a large number of cables to the surface of the display screen, these cables are prone to getting tangled with the bracket, which in turn affects the subsequent angle adjustment of the bracket.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a heat exchange device for the outlet of a tubular reactor, including a plate heat exchanger. Several uniformly distributed heat exchange plates are installed on the inner wall of the mounting frame of the plate heat exchanger. Two inlets and outlets are provided on one side surface of the mounting frame. A safety device is provided on the surface of the plate heat exchanger at the position of the heat exchange plates. The safety device uses a protective plate to shield and protect the heat exchange plates in use.
[0006] The effect achieved by the above components is as follows: when protecting the heat exchange plates on the plate heat exchanger, firstly, the inlet and outlet of the plate heat exchanger are sequentially and orderly connected to the pipelines of the tubular reactor, and finally, the safety device is assembled on the mounting frame to protect the heat exchange plates.
[0007] Preferably, the safety device includes a mounting plate assembled on a mounting frame. Several evenly distributed screws are fixedly connected to both sides of the surface of the mounting plate. A protective plate is installed on the screws on the same side of the mounting plate, and a nut is threaded onto the arc surface of the screw. Fixed frames are installed on the protective plates on both sides of the surface of the mounting plate. The fixed frames on both sides of the plate heat exchanger are connected and fixed by connecting plates.
[0008] The effect achieved by the above components is that when the plate heat exchanger is installed at the outlet of the tubular reactor, it can provide a certain degree of protection for the heat exchange plate, making it less likely to come into contact with or collide with external objects in the working environment, thus preventing damage to the heat exchange plate, fluid leakage, and reducing safety hazards during use.
[0009] Preferably, the safety device further includes an operating block mounted on the surface of the nut, wherein the operating block assists in the use of the nut.
[0010] The effect achieved by the above components is that the operation block makes it easier to rotate the bolt during use, thereby making the disassembly and assembly of the safety device more convenient.
[0011] Preferably, the safety device further includes a reinforcing plate mounted on the surface of the screw on one side of the fixed frame, wherein the reinforcing plate enhances the installation effect of the nut.
[0012] The effect achieved by the above components is that, by setting up the reinforcing plate, when the nut is installed on the screw, it can be pressed against the reinforcing plate surface that penetrates through the screw surface, making the nut more stable and fit better, and less prone to rotation and loosening.
[0013] Preferably, the safety device further includes a reinforcing pad installed on the inner wall of the protective plate, wherein the reinforcing pad enhances the effectiveness of the protective plate.
[0014] The effect achieved by the above components is that, through the setting of the rubber reinforcing pad, the impact force can be reduced when the protective plate comes into contact with the heat exchange plate, thereby better protecting the heat exchange plate.
[0015] Preferably, the surface of the mounting frame is provided with a protective device at the inlet and outlet positions. The protective device includes a protective cover, which covers the surface of the inlet and outlet. The protective cover has slots on both sides of its surface, and the inner wall of the slots is installed on a plate, which is connected to the surface of the mounting frame.
[0016] The effect achieved by the above components is that during maintenance and relocation of the plate heat exchanger, foreign objects are less likely to enter the inlet and outlet, thus ensuring stable fluid flow and enabling the plate heat exchanger to operate normally.
[0017] Preferably, the protective device further includes a connecting rope installed on the surface of the protective cover, wherein the other end of the connecting rope is connected to the surface of the mounting frame.
[0018] The effect achieved by the above components is that the connecting rope makes the protective cover easier to remove during use, thereby improving the ease of use of the protective device when protecting the inlet and outlet of the independent plate heat exchanger.
[0019] Preferably, the protective device further includes a reinforcing sleeve installed on the inner wall of the protective cover, wherein the reinforcing sleeve assists in the installation and fixation of the protective cover.
[0020] The effect achieved by the above components is that when the protective cover is covered on the surface of the inlet and outlet by the sponge material reinforcement sleeve, the reinforcement sleeve fixedly connected to the inner wall of the reinforcement sleeve will make stable contact with the pipes on the inlet and outlet, making the protective cover more stable and less likely to fall off.
[0021] The beneficial effects of this utility model are:
[0022] When the plate heat exchanger of this utility model is installed at the outlet of a tubular reactor, it can provide a certain degree of protection for the heat exchange plate, making it less likely to come into contact with or collide with external objects in the working environment, thus preventing damage to the heat exchange plate and fluid leakage, thereby reducing safety hazards during use.

[0031] Figure 1 and Figure 2 The heat exchange device at the outlet of a tubular reactor shown includes a plate heat exchanger 1. Several evenly distributed heat exchange plates 7 are installed on the inner wall of the mounting frame 6 of the plate heat exchanger 1. Two inlets 4 and outlets 5 are provided on one side surface of the mounting frame 6. A safety device 2 is provided on the surface of the plate heat exchanger 1 at the position of the heat exchange plates 7. The safety device 2 protects the heat exchange plates 7 in the use state by means of a protective plate 23. A protective device 3 is provided on the surface of the mounting frame 6 at the positions of the inlets 4 and outlets 5.
[0032] Figure 1 and Figure 2 The safety device 2 shown includes a mounting plate 21 mounted on a mounting frame 6. Several evenly distributed screws 22 are fixedly connected to both sides of the surface of the mounting plate 21. A protective plate 23 is mounted on the screws 22 on the same side of the mounting plate 21, and nuts 24 are threaded onto the arc surfaces of the screws 22. Fixing frames 25 are mounted on the protective plates 23 on both sides of the mounting plate 21. The fixing frames 25 on both sides of the plate heat exchanger 1 are connected and fixed via connecting plates 26. When protecting the heat exchange plates 7 on the plate heat exchanger 1, firstly, the inlet and outlet 5 of the plate heat exchanger 1 are sequentially connected to the pipelines of the tubular reactor. Then… Two protective plates 23 are respectively installed through the screws 22 on both sides of the mounting plate 21. Then, nuts 24 are installed on the screws 22 until the nuts 24 come into contact with and press against the surface of the protective plates 23. At the same time, the two sides of the connecting plate 26 are respectively inserted into the inner wall of the fixing frame 25 fixedly connected to the surface of the protective plate 23. At this time, the protective plates 23 will shield and cover the heat exchange plates 7 assembled on the mounting frame 6. When the plate heat exchanger 1 is installed at the outlet of the tubular reactor, it can provide a certain protection for the heat exchange plates 7, making it less likely to come into contact with or collide with external objects in the working environment, which could lead to damage to the heat exchange plates 7, fluid leakage, and reduced safety hazards.
[0033] Figure 1 and Figure 2 The safety device 2 shown also includes an operating block 27 installed on the surface of the nut 24. The operating block 27 assists in the use of the nut 24. The setting of the operating block 27 makes it easier to rotate the bolt during use, thereby making the disassembly and assembly of the safety device 2 more convenient. The safety device 2 also includes a reinforcing plate 28 mounted on the surface of the screw 22 on one side of the fixed frame 25. The reinforcing plate 28 enhances the installation effect of the nut 24. With the setting of the reinforcing plate 28, when the nut 24 is installed on the screw 22, it can be pressed against the surface of the reinforcing plate 28 that penetrates through the screw 22, making the nut 24 more stable and fit, and less prone to rotation and loosening. The safety device 2 also includes a reinforcing pad 29 installed on the inner wall of the protective plate 23. The reinforcing pad 29 enhances the use effect of the protective plate 23. With the setting of the rubber reinforcing pad 29, when the protective plate 23 is impacted and comes into contact with the heat exchange plate 7, the impact force can be reduced, thereby better protecting the heat exchange plate 7.
[0034] Figure 1 and Figure 2 The protective device 3 shown includes a protective cover 31, which covers the surfaces of the inlet 4 and outlet 5. The protective cover 31 has slots 32 on both sides of its surface. The inner walls of the slots 32 are fitted with insert plates 33, which are connected to the surface of the mounting frame 6. When the plate heat exchanger 1 is being transferred, transported, or repaired, the protective cover 31 is first placed over the pipes at the inlet 4 and outlet 5. At this time, the slots 32 on both sides of the protective cover 31 will insert and engage with the insert plates 33 connected to the surface of the mounting frame 6, thus fixing the position of the protective cover 31. During this time, foreign objects are less likely to enter the inlet 4 and outlet 5 of the plate heat exchanger 1 during repair and transfer, ensuring stable fluid flow and allowing the plate heat exchanger 1 to operate normally.
[0035] Figure 1 and Figure 2 The protective device 3 shown also includes a connecting rope 35 installed on the surface of the protective cover 31, wherein the other end of the connecting rope 35 is connected to the surface of the mounting frame 6. The setting of the connecting rope 35 makes the protective cover 31 easier to take out during use, thereby improving the ease of use of the protective device 3 when protecting the inlet 4 and outlet 5 of the independent plate heat exchanger 1. The protective device 3 also includes a reinforcing sleeve 34 installed on the inner wall of the protective cover. The reinforcing sleeve 34 assists in the installation and fixation of the protective cover 31. When the protective cover 31 is covered on the surface of the inlet 4 and outlet 5 by the reinforcing sleeve 34 made of sponge material, the reinforcing sleeve 34 fixedly connected to the inner wall of the reinforcing sleeve 34 will make stable contact with the pipes on the inlet 4 and outlet 5, making the protective cover 31 more stable and less likely to fall off.
[0036] Working principle: When protecting the heat exchange plates 7 on the plate heat exchanger 1, firstly, the inlet and outlet 5 of the plate heat exchanger 1 are sequentially and orderly connected to the pipelines of the tubular reactor. Then, two protective plates 23 are installed through the screws 22 on both sides of the mounting plate 21. Then, nuts 24 are installed on the screws 22 until the nuts 24 are pressed against the surface of the protective plates 23. At the same time, the two sides of the connecting plate 26 are respectively inserted into the inner wall of the fixing frame 25 fixedly connected to the surface of the protective plates 23. At this time, the protective plates 23 will shield and cover the heat exchange plates 7 assembled on the mounting frame 6. When the plate heat exchanger 1 is installed at the outlet of the tubular reactor, it can provide a certain degree of protection for the heat exchange plates 7, making it less likely to come into contact with or collide with external objects in the working environment, thus preventing damage to the heat exchange plates 7, fluid leakage, and reducing safety hazards.
[0037] When the plate heat exchanger 1 is transferred, transported, or inspected and maintained, the protective cover 31 is first placed over the pipes at the inlet 4 and outlet 5. At this time, the slots 32 on both sides of the surface of the protective cover 31 will be inserted and engaged with the connecting plates 33 on the surface of the mounting frame 6, thereby fixing the position of the protective cover 31. At this time, during the inspection and transfer of the plate heat exchanger 1, it is not easy for foreign objects to enter the inlet 4 and outlet 5, thus ensuring the stable flow of fluid and enabling the plate heat exchanger 1 to operate normally.
