Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to an inclined plate heat exchange device. Background Art

[0002] The interlayer heat exchanger is formed by a sandwich between two adjacent plates. The cold and hot fluids are separated by a solid wall (tube or plate) and do not mix. It involves the transfer and conversion of heat. The heat exchange is carried out through the interlayer to make the fluid temperature reach the specified index of the process to meet the needs of the process conditions. The gap between the two plates is usually connected by a pipe or a sealing gasket to form a closed environment that can loosely accommodate the flow and transfer of materials. It is suitable for high temperature, high pressure, high viscosity, and easy to scale fluids.

[0003] In the process of heat exchange, the existing heat exchanger guides the fluid from top to bottom to perform multi-stage heat transfer. However, the fluid flows slowly during the downward flow and heat exchange process, and there are places where the fluid cannot flow or has poor fluidity at the side positions during the flow. Not only is it easy to have dead water areas, affecting the heat exchange effect, but also foreign matter such as impurities in the fluid is easy to settle, causing blockage of the heat exchanger. Utility Model Content

In this solution, under the action of the guide sloping plates, the fluid flows into the confluence outlet at the downward inclined end of the guide sloping plates; by processing the inclined surface of the guide sloping plates of the heat exchange plates, the fluid can be guided on the heat exchange plates, and the fluid is guided to the confluence outlet provided at the lowest inclined position, so as to prevent the poor heat exchange effect caused by the non-flow of the fluid. Such a design, on the one hand, can effectively avoid the formation of dead water areas in the heat exchanger for high-quality fluids, and can ensure the heat exchange effect. On the other hand, for poor-quality fluids, it can effectively increase the fluidity of the liquid, prevent the sedimentation and accumulation of foreign matter such as impurities in the fluid, thereby effectively preventing the heat exchanger from being blocked during the heat exchange process, and ensuring that the heat exchanger can operate stably for a long time.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims.

[0027] It should be noted that all actions to obtain signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0028] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined according to the corresponding parts' own contours. The terms used in the present disclosure, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance.

[0029] Embodiment 1:

[0030] like Figure 1 to Figure 2 As shown, the present embodiment provides an inclined plate heat exchange device, comprising a plurality of heat exchange plate groups, characterized in that: the heat exchange plate group is composed of a heat exchange plate 1, the heat exchange plate 1 is provided with a guide inclined plate 2, the heat exchange plate 1 has a confluence outlet 4, and the confluence outlet 4 is arranged at the low inclined end of the guide inclined plate 2.

[0031] The heat exchanger group includes a plurality of inclined heat exchanger plates 13, and the guide inclined plates 2 of the inclined heat exchanger plates 13 are configured as plane guide inclined plates 23, such as Figure 2 The confluence outlet 4 of the inclined heat exchange plate 13 is arranged at the side, and the confluence outlets 4 in the heat exchange plate group are arranged in a staggered manner, so that a Z-shaped material flow layer is formed between the heat exchange plate groups.

[0032] Under the inclination of the planar guide inclined plate 23, the fluid on the inclined heat exchange plate 13 can be guided to the lower end of the inclination, driving the fluid to flow faster on the inclined surface, and the converging outlets of two adjacent inclined heat exchange plates 13 in the heat exchange plate group are staggered, and the flat inclined surfaces of adjacent inclined heat exchange plates are also placed in the opposite direction, so that the converging outlets 4 are staggered to form a Z-shaped material flow layer, thereby fully utilizing the material flow layer area of ​​the heat exchange plate 1.

[0033] The inclination angle of the planar guide inclined plate 23 is set to 1-3°, and the fluid can flow toward the confluence outlet 4 on the planar guide inclined plate 23 under the action of gravity. If the inclination angle of the planar guide inclined plate 23 is too large, it will cause the fluid to flow too fast on the heat exchange plate. The fluid enters the confluence outlet 4 for discharge before it has fully contacted the heat exchange plane for heat exchange, resulting in poor heat exchange effect. In this embodiment, the inclination angle of the inclined surface 5 is set to between 1-3°, so that the fluid flow speed is controlled within a controllable range.

[0034] Embodiment 2:

[0035] like Figure 3-Figure 8 As shown, an inclined plate heat exchange device includes multiple heat exchange plate groups, characterized in that: the heat exchange plate group is composed of a heat exchange plate 1, the heat exchange plate 1 is provided with a guide inclined plate 2, the heat exchange plate 1 has a confluence outlet 4, and the confluence outlet 4 is arranged at the low inclined end of the guide inclined plate 2.

[0036] The heat exchanger group includes a plurality of diverter heat exchanger plates 11 and converging heat exchanger plates 12, and the diverter heat exchanger plates 11 and the converging heat exchanger plates 12 are alternately stacked; the converging outlets 4 of the diverter heat exchanger plates 11 are arranged around the heat exchanger plates 1, and the converging outlets 4 of the converging heat exchanger plates 12 are arranged in the middle of the heat exchanger plates 1. Figure 3 shown.

[0037] Due to the different types of heat exchanger plates 1, the guide inclined plate 2 of the diverter heat exchanger plate 11 is configured as a convex guide inclined plate 21, such as Figure 4 As shown, the guide inclined plate 2 of the converging heat exchange plate 12 is configured as a concave guide inclined plate 22, as shown in FIG. Figure 6 By making the guide inclined plate 2 of the heat exchange plate 1 convex and concave, the fluid can be guided on the heat exchange plate 1 and directed to the confluence outlet 4 set at the lowest inclined position to prevent poor heat exchange effect caused by fluid stagnation.

[0038] During the process of alternating use of the two types of heat exchanger plates, when the fluid flows into the surface of the diverter heat exchanger plate 11, the fluid flows from the convex guide ramp 21 of the diverter heat exchanger plate 11 to the confluence outlet 4 arranged around the heat exchanger plate, and the fluid after being diverted by the confluence outlet 4 around the upper heat exchanger plate falls to the surrounding positions of the lower confluence heat exchanger plate 12. The fluid that falls to the surrounding positions of the confluence heat exchanger plate 12 flows to the confluence outlet 4 arranged in the middle position of the confluence heat exchanger plate 12 under the guiding action of the concave guide ramp 22.

[0039] The guide inclined plate 2 of the diverter heat exchanger plate 11 is set as a convex guide inclined plate 21 so that the fluid on the diverter heat exchanger plate 11 is guided from the middle to the side on the guide inclined plate 2 that bulges upward in the middle position. The guide inclined plate 2 of the converging heat exchanger plate 12 is set as a concave guide inclined plate 22 so that the fluid on the converging heat exchanger plate 12 is guided from the side to the middle on the guide inclined plate 2 that is concave downward in the middle position.

[0040] like Figure 7 As shown, the concave guide inclined plate 21 is provided with four downward converging inclined surfaces, and the interior of the converging heat exchange plate 12 is a pyramidal groove structure; Figure 8 As shown, the convex guide inclined plate 21 is provided with four upward diversion inclined surfaces, and the interior of the diversion heat exchange plate 11 is a pyramid-shaped platform structure.

[0041] The heat conducting plate 1 of this embodiment is a rectangular structure, and the guide ramp 2 formed by the split heat exchange plate 11 or the converging heat exchange plate 12 is composed of four separate convex guide ramps 21 or four separate concave guide ramps 22 spliced ​​together on the side. The convex guide ramp 21 is formed by rotating upward a° with the bottom plate 3 as the reference plane and the side as the rotation center, and the concave guide ramp 22 is formed by rotating downward a° with the bottom plate 3 as the reference plane and the side as the rotation center, and the inclination angle a is 1°-3°; in this embodiment, the inclination angle a of the guide ramp is set between 1° and 3°, and the speed of the fluid flow is controlled within a controllable range, so that the speed of the fluid will not be too fast, resulting in the fluid on the upper surface of the heat exchange plate entering the converging outlet 4 for discharge before it has fully contacted with the heat exchange plane of the heat exchange plate for heat exchange, resulting in poor heat exchange effect, and the inclination angle of the guide ramp 2 is too small, and the effect of accelerating the drainage cannot be achieved under the action of fluid tension, thereby affecting the heat exchange effect.

[0042] In addition to the structure of the splitter heat exchanger 11 or the converging heat exchanger 12 of the present embodiment, the splitter heat exchanger 11 can also adopt a conical platform structure to achieve an upward convex effect, and the converging heat exchanger 12 can also adopt an integral funnel-shaped structure to achieve a downward concave effect.

[0043] The side height of the diverter heat exchanger 11 is set to h2, and the middle height of the diverter heat exchanger 11 is set to h1; the side height of the converging heat exchanger 12 is set to h1, and the middle height of the diverter heat exchanger 11 is set to h2; h1>h2, then the inside of the diverter heat exchanger 11 is convex upward, and the inside of the converging heat exchanger 12 is concave downward, such as Figure 5-Figure 6 shown.

[0044] Among them, an inclined surface is set between the side of each convex guide inclined plate 21 of the split heat exchange plate 11 and the confluence outlet 4, and the inclination angle at this place is b°; so that when the fluid flowing from the top of the split heat exchange plate 11 to the lower end is guided to the confluence outlet 4, part of the fluid is guided to the side edge position due to route deviation, resulting in retention, such as Figure 5 As shown; in this embodiment, an inclined surface is set again between the edge position of the diverter heat exchange plate 11 and the confluence outlet 4 so that an inclined surface is also formed between the edge position and the confluence outlet. The confluence outlet 4 is used as an inclined low position for drainage, so that the fluid on the diverter heat exchange plate 11 is fully drained to the confluence outlet 4, thereby improving the heat exchange effect.

[0045] Example 3

[0046] The heat exchange device also includes an upper sealing plate 6, a lower sealing plate 7 and a fastening mechanism 8. A plurality of heat exchange plates 1 are stacked between the upper sealing plate 6 and the lower sealing plate 7. The fastening mechanism 8 is arranged on the sides of the upper sealing plate 6, the lower sealing plate 7 and the plurality of heat exchange plates 1. The side edges of the interlayer formed between the upper sealing plate 6, the lower sealing plate 7 and the plurality of layers of heat exchange plates 1 are sealed by a sealing ring 9.

[0047] The upper sealing plate 6 is provided with a feed inlet 61, and the lower sealing plate 7 is provided with a discharge port 71. The heat exchanger is connected to the feed device through the feed inlet 61 provided on the upper sealing plate 6, and the feed device passes cold running water into the heat exchanger, and the cold running water enters the heat exchanger through the feed inlet 61 to start heat exchange treatment. The upper sealing plate 6 is installed on the top of the heat exchange device, and the lower sealing plate 7 is installed on the bottom of the heat exchange device.

[0048] like Figure 1 As shown, when the heat exchange device of this embodiment adopts the heat exchange plate group of embodiment 1, the number of the inlets 61 and the outlets 71 arranged on the upper sealing plate 6 and the lower sealing plate 7 is consistent with the number of the converging outlets 3 of the inclined heat exchange plate 13, the position of the inlet 61 and the converging outlet 4 of the inclined heat exchange plate 13 arranged on the uppermost layer of the heat exchange device are staggered on both sides, the upper surface of the lower sealing plate 7 is in contact with the inclined heat exchange plate 13 arranged on the lowermost layer, and the outlet 71 is aligned with the position of the converging outlet 4 of the inclined heat exchange plate 13 arranged on the lowermost layer of the heat exchange device.

[0049] The position of the discharge port 12 is aligned with the position of the confluence outlet 3 of the heat exchange plate arranged at the bottom layer of the heat exchange device. The upper surface of the bottom plate 9 abuts against the heat exchange plate arranged at the bottom layer. Support feet are arranged at the bottom of the bottom plate 9. The bottom plate serves as a bottom supporting structure to support the entire heat exchanger.

[0050] like Figure 3 As shown, when the heat exchange device of this embodiment adopts the heat exchange plate group of embodiment 3, the uppermost heat exchange plate arranged below the upper sealing plate 6 is the diversion heat exchange plate 11, and the lowermost heat exchange plate above the lower sealing plate 7 is the confluence heat exchange plate 12.

[0051] The inlet 61 of the upper sealing plate 6 is set in the middle position, and the lower layer of the upper sealing plate 6 is provided with a diversion heat exchange plate 11 so that the cold water introduced from the inlet 61 in the middle position of the upper sealing plate 6 can enter the heat exchange device and then fall to the highest inclined position of the middle position of the convex guide inclined plate 21 of the diversion heat exchange plate 11 and be diverted. The cold water flow is divided into multiple flow paths by the multiple convex guide inclined plates 21 provided on the diversion heat exchange plate 11 and guides the confluence outlet 4 at the inclined low position of the side of the heat exchange plate to realize the flow from the middle position to the surrounding sides; the cold fluid after being diverted by the confluence outlet 4 provided around the diversion heat exchange plate 11 falls to the surrounding positions of the confluence heat exchange plate 12 of the lower layer, and the confluence heat exchange plate 12 The cold fluid at the surrounding positions is merged to the confluence outlet 4 set in the middle position of the converging heat exchange plate 12 under the guiding effect of the concave guide inclined plate 22 at the highest inclination position of the surrounding sides, so as to realize the flow from the surrounding sides to the middle position; the cold flowing water flowing out of the confluence outlet 4 in the middle position of the converging heat exchange plate 12 repeats the path of the above steps until it flows into the bottom layer of the heat exchange plate 1. The bottom layer of the heat exchanger device of this embodiment adopts the converging heat exchange plate 12, and the bottom plate 3 of the bottom layer of the converging heat exchange plate 12 is in close contact with the lower sealing plate 7, and the discharge port 71 of the lower sealing plate 7 is opened in the middle position so that it is coaxial with the converging outlet of the converging heat exchange plate 12.

[0052] The fluid cavity 5 of the heat exchange plate 1 is connected through a U-shaped tube 53, the bottom end of the U-shaped tube 53 is connected to the water outlet interface 52, and the top end of the U-shaped tube 53 is connected to the water inlet interface 51. A fluid cavity 5 is formed between the guide inclined plate 2 and the bottom plate 3 of the heat exchange plate 1, and a water inlet interface 51 and a water outlet interface 52 are respectively provided on both sides of the heat exchange plate 1, and the water inlet interface 51 and the water outlet interface 52 are connected to the fluid cavity 5 inside the heat exchange plate 1. This solution adopts the method of transporting the fluid in the fluid cavity 5 from the bottom to the top of the heat exchanger. After the water inlet joint 51 of the heat exchange plate 1 set at the bottom layer is connected to the external water source joint 52, the bottom end of the U-shaped tube 53 set at the bottom layer is connected to the water outlet interface 52 of the heat exchange plate at the bottom layer, and the top end of the U-shaped tube 53 at the bottom layer is connected to the water inlet interface 51 of the heat exchange plate at the second bottom layer. After being connected in sequence, the water outlet joint 52 of the top heat exchange plate is connected to the wastewater treatment mechanism, so that the fluid cavity 5 in several heat exchange plates 1 is made into a channel for continuous upward flow through multiple U-shaped tubes 53. In addition, a reinforcing rib plate is set in the fluid cavity 5, so that the reinforcing rib plate in the fluid cavity 5 has one or more water channels between the water inlet interface and the water outlet interface, so that the fluid in the fluid cavity 5 stays for a longer time, improves the heat exchange effect of the heat exchanger, slows down the fluid velocity in the fluid cavity 5, so that the fluid in the fluid cavity 5 is fully heat exchanged with the fluid on the surface of the heat exchange plate 1, and increases the flow velocity in the fluid cavity 5, which can effectively save energy and reduce emissions.

[0053] Example 4

[0054] like Figure 1 As shown, the fastening mechanism 8 is composed of an adjusting screw 81, a locking nut 82 sleeved on the adjusting screw 81, a reinforcing plate 83 and a fixing seat 84. The reinforcing plate 83 is fixed on the outside of the fixing seat 84. The locking nut 82 and the adjusting screw 81 are movably connected by threads. The reinforcing plate 83 is respectively arranged on the upper surface of the upper sealing plate 6 and the bottom surface of the lower sealing plate 7. The adjusting screw, through the action of the locking nut, makes the reinforcing plate abut against and tighten against the upper sealing plate and the top plate, so that the fixing of the fastening mechanism is relatively stable. Compared with fixing methods such as screws or adhesion, it will not cause damage to the heat exchanger, thereby improving the efficiency of installation and disassembly.

[0055] The fastening mechanism 8 is arranged on all sides of the heat exchange device, and two or more fastening mechanisms 8 are evenly arranged on each side of the heat exchange device, so that the force of the heat exchange device after assembly is uniform, and the sealing effect and stability effect of the heat exchange device are improved. In the actual use process, when the upper sealing plate 6, a plurality of heat exchange plates 1 and the lower sealing plate 7 of the heat exchanger are installed layer by layer, since the side edges of the heat exchange plates 1 have a certain inclination angle, there is a height difference in the height of the outer periphery of the heat exchange plates 1. The upper sealing plate 6 and the lower sealing plate 7 are squeezed by the fastening mechanism 8, and the sealing ring 9 realizes a tight seal according to the fastening pressure of the fastening mechanism 8, and the sealing ring 9 realizes adaptive adjustment of the inclined surface.

[0056] After installation, the heat exchanger is rectangular or square in shape. The area of ​​each heat exchanger plate is mainly determined by the amount of material.

[0057] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
