Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and in particular to a tube sheet coupling enhanced heat exchanger. Background Art

[0002] Shell and tube heat exchanger, also known as shell and tube heat exchanger, is a wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat exchange surface. The heat exchange medium enters from the inlet of the shell and comes into direct contact with the outer surface of the tube bundle, thereby achieving the purpose of heat exchange. Shell and tube heat exchanger has a simple structure, low cost, a wide range of material selection, can meet the needs of high temperature and high pressure fluids, and works reliably, accounting for about 70% of the total heat exchangers. Therefore, it occupies a dominant position in the application of chemical, petroleum energy, refrigeration and heating industries.

[0003] Among them, the invention with application number CN202280055587.9 discloses a heat exchange module, which is composed of heat exchange elements, including a heating (cooling) medium block composed of the inner surface of an outer pipe and the outer surface of an inner pipe, with an annular gap between them; a heating (cooling) medium block composed of the outer surface of an outer pipe and the inner surface of an inner pipe; a tube sheet for fixing the inlet chamber and the outlet chamber of the outer pipe; and the bottom of the inlet chamber and the outlet chamber for fixing the inlet pipe and the outlet pipe. The medium enters the annular gap vertically or coaxially and exits the heat exchange tube. The number of heat exchange elements ranges from 2 to 3000. The modules can be connected in sections of 2 to 1000 to obtain the desired heat transfer surface. The arrangement of the modules can be multi-channel.

[0062] The present invention is described in detail below with reference to the accompanying drawings.

[0063] like Figure 1-13 As shown, a tube sheet coupled enhanced heat exchanger includes a heat exchange shell 1, one end of the heat exchange shell 1 is provided with a first fluid inlet 11 for a first liquid to flow in, and the other end is provided with a first fluid outlet 12, the heat exchange shell 1 includes a first chamber 13 connected to the first fluid inlet 11 and a second chamber 14 connected to the first fluid outlet 12, and also includes a third chamber 17 located between the first chamber 13 and the second chamber 14; the first liquid enters the first chamber 13 through the first fluid inlet 11, then flows into the second chamber 14 through the third chamber 17, and finally is discharged through the first fluid outlet 12, so that the flow of the first liquid is realized.

[0064] A heat exchange tube bundle 15 is arranged between the first chamber 13 and the second chamber 14, and the number of the heat exchange tube bundles 15 is multiple. The baffle 4 is provided with multiple through holes 16 for the heat exchange tube bundles 15 to pass through. A connection structure is arranged between the baffles 4, and the connection structure includes a first connection structure and a second connection structure. The first connection structure and the second connection structure are alternately connected between two adjacent baffles 4. The first connection structure includes an expansion joint 41, and the second connection structure includes a connecting pipe 42. The baffle 4 is formed with a flow cavity 43 of a hollow structure, and the expansion joint 41 and the connecting pipe 42 are respectively inserted into the flow cavity 43 of the baffle 4. The first liquid in the first chamber 13 can be fully flowed into the flow cavity 43 in the baffle 4 through the cooperation of the first connection structure and the second connection structure, and then flow from the baffle 4 to the second chamber 14 in turn to achieve heat exchange with the third chamber 17. In this embodiment, the present invention can increase the heat transfer of the shell and tube heat exchanger by tube sheet coupling while satisfying the function of the baffle 4 to change the shell-side fluid flow path, and at the same time use the expansion joint 41 to overcome the problem of thermal expansion of the baffle 4.

[0065] Specifically, an inlet pipe 25 is connected between the flow cavity 43 of the baffle plate 4 close to the first chamber 13 and the first chamber 13 , and the first liquid in the first chamber 13 can flow into the baffle plate 4 of the third chamber 17 through the inlet pipe 25 .

[0066] Preferably, a first sealing plate 2 and a second sealing plate 21 are arranged between the first chamber 13 and the third chamber 17, a third sealing plate 31 is arranged between the second chamber 14 and the third chamber 17, and an outer ring sealing ring 22 is installed between the first sealing plate 2 and the second sealing plate 21; the first sealing plate 2 is formed with a first tube hole 23 protruding toward the second sealing plate 21, the second sealing plate 21 is provided with a second tube hole 24 for inserting the inlet pipe 25, the inlet pipe 25 is formed with a flaring structure 26, the flaring structure 26 is sleeved with an inner ring sealing ring 27, and the first tube hole 23 is inserted into the flaring structure 26 of the second tube hole 24. In this embodiment, one end of the inlet pipe 25 is first passed through the first sealing plate 2 and the second sealing plate 21 in sequence. After being installed in place, the flared structure 26 at the outer end of the inlet pipe 25 cooperates with the second tube hole 24, and then the first tube hole 23 of the first sealing plate 2 is embedded in the flared structure 26 of the inlet pipe 25 to ensure that the first tube hole 23 is sealed and connected with the second tube hole 24, and the inner ring sealing ring 27 is cooperated to seal the inlet pipe 25 to connect it to the first chamber 13.

[0067] An outlet pipe 3 is connected between the flow cavity 43 of the baffle plate 4 near the second chamber 14 and the second chamber 14. An internal thread structure 33 is provided at the outlet end of the outlet pipe 3. A third tube hole 32 coaxially aligned with the outlet pipe 3 is formed on the third sealing plate 31. The third tube hole 32 is convexly oriented toward the third chamber 17. The third tube hole 32 is formed with an external thread structure 34 that matches the internal thread structure 33 of the outlet pipe 3. In this embodiment, the second chamber 14 and the third chamber 17 are sealed by the outlet pipe 3. The sealing connection is completed by the external thread structure 34 of the third tube hole 32 and the internal thread structure 33 of the outlet pipe 3. This design aims to achieve the flexibility of the heat exchange tube group. Each heat exchange tube is independent of each other and complementary. In the later application process, if the heat exchange tube is damaged, it can be easily replaced and maintained. At the same time, the baffle plate 4 is fixed to the shell of the third chamber 17 by fastening bolts and can be freely disassembled.

[0068] A second fluid inlet 44 for the second liquid to flow into is provided at one end of the top of the third chamber 17, and a second fluid outlet 47 is provided at the other end of the bottom of the third chamber 17. The third chamber 17 is equipped with a plurality of baffles 4, two adjacent baffles 4 are arranged at intervals, and two adjacent baffles 4 are fixedly connected to each other, and the baffles 4 are formed with cutting notches 45 and circular through holes 46 for the liquid to pass through, and the cutting notches 45 of the two adjacent baffles 4 are in opposite positions; when the second liquid flows into the third chamber 17 through the second fluid inlet 44, due to the blocking effect of the baffle 4, that is, the cutting notches 45 of the two adjacent baffles 4 are in opposite positions, the second liquid flows downward, and under the blocking of the adjacent baffles 4, it flows upward to the cutting notch 45, and under the action of the fluid pressure difference on both sides of the baffle 4, the second liquid flows through the circular through hole 46 of the baffle 4, and this is repeated, and finally discharged through the second fluid outlet 47, thereby improving the influence of the flow dead zone in the shell side on the fluid heat exchange, thereby improving the heat exchange efficiency of the shell and tube heat exchanger.

[0069] The baffle 4 is formed with a circular through hole 46 for the second liquid to pass through. The circular through hole 46 is sealed and separated from the flow chamber 43. There are four circular through holes 46, which are symmetrically arranged along the center line of the baffle 4. After the second liquid enters the third chamber 17, a part of the liquid will flow straight forward through the circular through hole 46, thereby generating a pressure difference of the fluid. Under the action of the fluid pressure difference on both sides of the baffle 4, after the second liquid flows into the bottom of the baffle 4, it will flow upward to the cutting notch 45 under the action of the pressure difference and continue to flow. This improves the influence of the flow dead zone in the shell side on the heat exchange of the fluid, thereby improving the heat exchange efficiency of the shell and tube heat exchanger.

[0070] In the heat exchanger of the present invention, the first fluid flows in the heat exchange tube bundle 15 and the baffle 4, and exchanges heat between the walls with the second fluid in the heat exchange shell 1, thereby improving the heat exchange efficiency and increasing the heat exchange amount. At the same time, the heat exchange tube 15 is easy to disassemble, which is beneficial to the later maintenance and replacement.

[0071] The second fluid outlet 47 is provided with a detection device 6, which includes a cylindrical frame 61.

[0072] The cylindrical frame 61 can be adapted to the cross-sectional shape of the second fluid outlet 47, and is convenient for being inserted into the second fluid outlet 47. The top mounting ring 62 and the bottom mounting ring 64 are fixed by a connecting column 65. The top mounting ring 62 and the bottom mounting ring 64 are respectively installed with connecting sleeves 66. The two ends of the connecting column 65 are respectively inserted into the connecting sleeves 66. The top mounting ring 62 and the middle mounting ring 63 and the bottom mounting ring 64 and the middle mounting ring 63 are connected by a fixing plate 67, thereby connecting the top mounting ring 62 and the bottom mounting ring 64. This makes the structure of the cylindrical frame 61 more stable; the detection camera 73 is installed on the bottom mounting ring 64 through the detection bracket 72. When the cylindrical frame 61 is inserted, the detection camera 73 can be used to shoot and detect the inner wall of the second fluid outlet 47 to check whether there is damage or accumulation of stone scale, which is convenient for returning data.

[0073] Preferably, the top mounting ring 62 and the bottom mounting ring 64 are respectively installed with a transverse plate 68, and both ends of the transverse plate 68 are respectively fixed to the connecting sleeve 66. Two connecting columns 65 are installed in parallel between the top mounting ring 62 and the bottom mounting ring 64 for fixing, thereby further improving the structural stability of the cylindrical frame 61.

[0074] Specifically, a pair of waterproof plates 70 are arranged between the top mounting ring 62, the middle mounting ring 63 and the bottom mounting ring 64.

Before the detection device 6 is used, the power supply battery can be charged through the charging port so that the detection device can be used normally; the circuit control board 71 is installed with a signal transmission module, and the signal transmission module can transmit the image information taken by the detection camera 73 to the terminal device, thereby realizing the detection of the inner wall of the second fluid outlet 47 to check whether there is any damage or accumulation of stone scale, which is convenient for returning data.

[0075] Specifically, the cylindrical frame 61 is provided with a moving mechanism capable of crawling along the inner wall of the second fluid outlet 47, the moving mechanism includes a plurality of cylindrical rods 74 installed on the cylindrical frame 61, the cylindrical rods 74 are provided with a crawling structure 7, the crawling structure 7 includes a first swing bar 75 which is swingably installed on the cylindrical frame 61, a guide roller 76 is installed on the outer end of the first swing bar 75, a moving seat 69 is slidably installed on the cylindrical rod 74, a second swing bar 77 is connected between the moving seat 69 and the first swing bar 75, the guide roller 76 installed on the outer end of the first swing bar 75 can roll with the inner wall of the second fluid outlet 47 to realize the overall advancement of the cylindrical frame 61.

[0076] Specifically, the cylindrical rod 74 is fixed between the top mounting ring 62 and the bottom mounting ring 64, and the middle mounting ring 63 is formed with a through hole 78 for the cylindrical rod 74 to pass through. The cylindrical rod 74 is embedded with an elastic compression spring 79. The elastic force of the elastic compression spring 79 drives the moving seat 69 to move outward to drive the first swing bar 75 to swing outward. Under the drive of the elastic compression spring 79, the driving seat will move outward along the cylindrical rod 74, and the inclination angle of the second swing bar 77 will be reduced, so that the first swing bar 75 will swing outward, and the guide roller 76 installed at the outer end of the first swing bar 75 can roll with the inner wall of the second fluid outlet 47. In this embodiment, when the detection device 6 enters the second fluid outlet 47 and passes through the second fluid outlet 47 in different spaces, the elastic compression spring 79 will adaptively drive the moving seat 69 to move along the cylindrical rod 74, so that the guide roller 76 is always in contact with the inner wall of the second fluid outlet 47 under the drive of the elastic force, so as to achieve rolling fit and maintain friction contact, so as to facilitate the detection device 6 to move forward or backward.

[0077] An insertion rod is installed at the other end of the cylindrical frame 61 , and the insertion rod can be pushed or pulled so that the cylindrical frame 61 can move forward or backward along the inner wall of the second fluid outlet 47 .

[0079] In one embodiment, when the liquid in the first chamber 13 is not fully filled or the liquid height is only 1 / 2, the heat exchange liquid will only enter the heat exchange tube bundle 15 from the lower first conduit 23 to achieve heat exchange. When there is more liquid in the heat exchange tube bundle 15, the heat exchange effect will be reduced; and no liquid will pass through the higher heat exchange tube bundle 15, resulting in heat exchange waste.

At this time, a part of the liquid can be pumped into the first guide pipe 84 through the pump body 83. Under the action of the pump body 83, the guide seat 86 and the discharge pipe 87, the liquid can pass into the first conduit located above the liquid level of the first chamber 13, so that most of the heat exchange tube bundle 15 can allow the liquid to pass through, ensuring that the liquid that needs to be heat exchanged can more fully cooperate with the heat exchange tube bundle 15 to absorb or release heat, thereby improving the utilization rate, achieving a better heat exchange effect, and the liquid will not be concentrated in a certain area.

[0081] It should be noted that the suction end of the pump body 83 is connected to an suction pipe, and the heat exchange shell is provided with a suction hole.

[0083] Furthermore, the flow guide structure 8 also includes a flipping drive mechanism 99 for driving the flow guide support frame 9 to rotate. The flipping drive mechanism 99 includes a support stand 991 located outside the first chamber 13. The support stand 991 is provided with a laterally arranged rotating drive shaft 992. The rotating drive shaft 992 is sleeved with a sealing bearing 993. The flow guide support frame 9 is provided with an inner connecting sleeve 994. The inner end of the rotating drive shaft 992 is connected to the inner connecting sleeve 994. The heat exchange shell 1 is formed with a driving hole 995 connected to the first chamber 13. The sealing bearing 993 is installed in the driving hole 995. One of the support stands 991 is provided with a driving motor 996 that is transmission-connected to the rotating drive shaft 992. The driving motor 996 shell drives the rotating drive shaft 992 to rotate. A sealed bearing 993 is provided in the driving hole 995, through which the rotating driving shaft 992 can pass in a sealed manner. When the rotating driving shaft 992 rotates, the liquid in the first chamber 13 will not leak, thereby driving the guide support frame 9 to rotate and flip, and the first guide pipe 84 of the guide chamber 81 is tilted downward, and the discharge pipe 87 is upward. At this time, a part of the liquid can be pumped into the first guide pipe 84 through the pump body 83. Under the action of the pump body 83, the guide seat 86 and the discharge pipe 87, the liquid can pass into the first conduit located above the liquid level in the first chamber 13, so that most of the heat exchange tube bundle 15 can allow liquid to pass, ensuring that the liquid that needs to be heat exchanged can more fully cooperate with the heat exchange tube bundle 15 to absorb or release heat, thereby improving the utilization rate, achieving a better heat exchange effect, and the liquid will not be concentrated in a certain area.

[0084] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.
