Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, specifically to a detachable reformer. Background Technology

[0002] Among existing heat exchangers, plate and shell heat exchangers can solve the problem of disassembly and inspection without secondary processing. However, plate and shell heat exchangers require high welding precision between the plate bundles and the shell, have a high scrap rate of plates, and require custom molds, resulting in high costs. The flow channels are narrow, and the plates are mostly corrugated, making it difficult to coat catalysts. Furthermore, the heat exchange method of autothermal reforming is not suitable for natural gas steam reforming reactions. Therefore, there is an urgent need for a reformer that is suitable for natural gas steam reforming reactions and is easy to disassemble and inspect without secondary processing.

[0046] This application provides a detachable reformer that solves the problems of existing reformers being difficult to disassemble for inspection and requiring secondary processing. It can also achieve multi-stage reforming by connecting multiple heat exchanger cores in series, thereby improving heat utilization.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] like Figures 1-4 and Figure 14 As shown, this application provides a detachable reformer, comprising:

[0049] Heat exchanger core 1, the length direction of heat exchanger core 1 is the first direction ( Figure 1 In the X direction, the heat exchanger core 1 has a first fluid inlet at one end in the first direction and a first fluid outlet at the other end in the first direction. Thus, the first fluid can enter the heat exchanger core 1 through the first fluid inlet, flow out through the first fluid outlet to the first fluid source, and then enter the heat exchanger core 1 again through the first fluid inlet, forming a circulation. The heat exchanger cores 1 can be connected in series along the first direction, and the first fluid outlet of one heat exchanger core 1 can be connected to the first fluid inlet of the adjacent heat exchanger core 1. The heat exchanger core 1 also has a second direction perpendicular to the first direction (…). Figure 1 In the Y direction), the heat exchanger core 1 is also provided with a second fluid inlet and a second fluid outlet in the second direction;

[0050] A first end cap 41 and a second end cap 42 are provided. The first end cap 41 is located at the second fluid inlet, and the second fluid inlet can be connected to the second fluid source through the first end cap 41. The second end cap 42 is located at the second fluid outlet, and the second fluid outlet can be connected to the second fluid source through the second end cap 42.

[0051] When disassembly is required, simply separate the multiple heat exchanger cores 1 connected in series and remove components such as the first end cap 41 and the second end cap 42 from the heat exchanger core 1. This solves the problem that existing reformers are not easy to disassemble for inspection and require secondary processing. By connecting multiple heat exchanger cores 1 in series, multi-stage reforming can be achieved, improving heat utilization.

[0052] In a preferred embodiment, such as Figure 5 and Figure 6 As shown, the heat exchanger core 1 also has a third direction perpendicular to the first direction and the second direction respectively. Figure 1 (in the Z direction), the heat exchanger core 1 includes a first flow channel plate 11 and a second flow channel plate 12 arranged alternately in the third direction, a partition 16 is provided between adjacent first flow channel plates 11 and second flow channel plates 12, and a core cover plate 17 is also provided at the outermost first flow channel plate 11 or second flow channel plate 12 in the third direction.

[0053] The first flow channel plate 11, together with the baffles 16 on both sides and the baffles 16 / core cover plate 17, forms a first flow channel that allows only the first fluid to pass through. The first fluid inlet is connected to the first fluid outlet through the first flow channel.

[0054] The second flow channel plate 12, together with the baffles 16 on both sides and the baffle / core cover plate 17, forms a second flow channel that allows only the second fluid to pass through. The second fluid inlet is connected to the second fluid outlet through the second flow channel.

[0055] The staggered first flow channel plate 11, second flow channel plate 12, and the partition plate 16 between adjacent first flow channel plates 11 and second flow channel plates 12, together with the core cover plate 17, constitute the heat exchanger core 1. The first flow channel formed by the first flow channel plate 11 and the partition plates 16 on both sides and the partition plate 16 / core cover plate 17 is only for the first fluid to pass through; the second flow channel formed by the second flow channel plate 12 and the partition plates 16 on both sides and the partition plate 16 / core cover plate 17 is only for the second fluid to pass through, thereby achieving heat exchange between the two fluids while isolating the first fluid and the second fluid.

[0056] In a preferred embodiment, such as Figure 7 , Figure 8 and Figure 10 As shown, the first flow channel plate 11 includes a first fin 151, and grooves extending in the first direction are evenly distributed on both sides of the third direction of the first fin 151; a side strip 14 is provided at the edge of the first fin 151 in the second direction, and the side strip 14 can fit between the partition plate 16 and the partition plate 16 / core cover plate 17 on both sides of the first flow channel plate 11.

[0057] In this embodiment, the grooves in the first fin 151 are aligned with the first direction. The first fluid can flow from one end of the groove along its length to the other end. That is, the first fluid enters the straight first flow channel formed by each groove through the first fluid inlet and then flows out from the first fluid outlet. Grooves extending along the first direction are evenly distributed on both sides of the third direction of the first fin 151. That is, the first fin 151 adopts a straight fin, which is conducive to catalyst coating (generally slurry coating followed by sintering) and is less likely to cause blockage or uneven coating.

[0058] In a preferred embodiment, such as Figure 9 and Figure 11 As shown, the second flow channel plate 12 includes a second fin 152, which includes a trapezoidal main body that is smaller at the top and larger at the bottom, and right-angled trapezoidal parts that are respectively spliced ​​on both sides of the trapezoidal main body in the first direction.

[0059] The trapezoidal main body has grooves extending in the first direction evenly distributed on both sides of the third direction, and the right trapezoidal part has grooves extending in the second direction evenly distributed on both sides of the third direction. The grooves on the trapezoidal main body and the right trapezoidal part form a U-shaped flow channel on the second fin 152.

[0060] The trapezoidal main body is provided with a side strip 14 at the edge in the second direction, and the right-angled trapezoidal part is provided with a side strip 14 at the edge in the first direction. The side strip 14 can fit between the partition 16 and the partition 16 / core cover plate 17 on both sides of the second flow channel plate 12.

[0061] In this embodiment, the second fin 152 is formed by splicing a trapezoidal main body and two right-angled trapezoidal parts. The hypotenuses of the two right-angled trapezoidal parts are respectively spliced ​​to the two hypotenuses of the trapezoidal main body, forming a roughly rectangular shape. The side strip 14 is provided on the left, lower, and right sides of the second fin 152, as well as the middle of the upper side of the second fin 152. The second flow channel plate 12 is closed to the outside through the side partitions 16 or the core cover plate 17, leaving only the second fluid inlet and second fluid outlet at the upper ends (i.e., the edges in the second direction) of the two right-angled trapezoidal parts, thereby forming a U-shaped second flow channel; specifically, as shown in the figure... Figure 9 and Figure 11 As shown, the second fluid flows through the second fluid inlet into the second flow channel, first downward, then to the right, then upward, and finally to the second fluid outlet. This achieves the purpose of setting the second fluid inlet and the second fluid outlet on the same side in the second direction, so that the heat exchanger core 1 can be placed into the cavity of the outer shell through an opening in the outer shell, and the second fluid inlet and the second fluid outlet on the same side are exposed to the outside through the opening and connected to the second fluid source.

[0062] In a preferred embodiment, such as Figures 1-3 , Figure 13 , Figure 14 As shown, the detachable reformer also includes a housing 2 and a first connecting flange 3; the housing 2 has a core placement port 23 in the second direction, and one or more heat exchanger cores 1 can be inserted into the inner cavity of the housing 2 through the core placement port 23 and fixed to the housing 2 through the first connecting flange 3;

[0063] The housing 2 is provided with a first opening 21 and a second opening 22 at both ends in the first direction. The first opening 21 at one end of the housing 2 in the first direction is connected to the adjacent first fluid inlet, and the second opening 22 at the other end of the housing 2 in the first direction is connected to the adjacent first fluid outlet. The first fluid inlet can be connected to the first fluid source through the first opening 21, and the first fluid outlet can be connected to the first fluid source through the second opening 22.

[0064] The second fluid inlet and the second fluid outlet are both located at positions corresponding to the core placement port 23.

[0065] The detachable reformer includes a heat exchanger core 1, a first end cap 41, and a second end cap 42, as well as a housing 2 and a first connecting flange 3. The first connecting flange 3 is used to fix the heat exchanger core 1 inside the housing 2. Depending on the actual situation, one or more heat exchanger cores 1 connected in series can be set, and the length of the housing 2 in the first direction is set according to the number of heat exchanger cores 1. The first connecting flange 3 can be fixed on one heat exchanger core 1, or multiple heat exchanger cores 1 can be connected in series through one first connecting flange 3, and then the heat exchanger core 1 is placed inside the housing 2 and fixedly connected to the outer periphery of the housing 2 through the first connecting flange 3. The first fluid can enter the housing 2 through the first opening 21 and flow back to the first fluid source through the first fluid inlet, the first fluid outlet, and the second opening 22. When disassembly is required, only the connecting parts such as screws connecting the first connecting flange 3 to the housing 2 need to be removed to remove the heat exchanger core 1 from the housing 2, thereby enabling catalyst coating and disassembly inspection, and enabling multi-stage reforming.

[0066] In a preferred embodiment, such as Figure 2 , Figure 3 and Figure 12 As shown, core baffles are respectively provided circumferentially at the first fluid inlet and the first fluid outlet, and a shell baffle 6 is also provided in the inner cavity of the shell 2. When the heat exchanger core 1 is provided in the inner cavity of the shell 2, the core baffles are attached to the shell baffle 6.

[0067] Since a gap inevitably exists between the heat exchanger core 1 and the inner cavity of the shell 2, core baffles 5 are respectively provided at the circumferential directions of the first fluid inlet and the first fluid outlet of the heat exchanger core 1, and shell 2 baffles are also added to the inner cavity of the shell 2. The cooperation of the core baffles and the shell baffles 6 prevents the first fluid from passing through the gap. The number of core baffles can be one; preferably, two core baffles are provided at the circumferential direction of the first fluid inlet and two core baffles are also provided at the circumferential direction of the first fluid outlet. Thus, if... Figure 12 As shown, the two core baffles can clamp the housing baffle 6 within them, thereby minimizing the passage of the first fluid through the gap.

[0068] like Figure 15As shown in the figure, this is a second embodiment of the detachable reformer of this application. The detachable reformer also includes a second connecting flange 7, a third end cap 43, and a fourth end cap 44. The second connecting flange 7 is provided at the first fluid inlet and the first fluid outlet respectively. The first fluid outlet of one heat exchanger core 1 can be connected to and communicated with the first fluid inlet of another heat exchanger core 1 through the second connecting flange 7. The second connecting flange 7 at the first fluid inlet can also be connected to the third end cap 43, and the first fluid inlet can be connected to the first fluid source through the third end cap 43. The second connecting flange 7 at the first fluid outlet can also be connected to the fourth end cap 44, and the first fluid outlet can be connected to the first fluid source through the fourth end cap 44.

[0069] In this embodiment, instead of a shell 2, second connecting flanges 7 are provided at the first fluid inlet and the first fluid outlet at both ends of the heat exchanger core 1 in the first direction. The heat exchanger core 1 is connected in series and fixed with the third end cap 43 and the fourth end cap 44 through the second connecting flanges 7. This scheme can also realize catalyst coating and disassembly inspection, and can realize multi-stage reforming.

[0070] In a preferred embodiment, such as Figure 15 As shown, the first end cap 41 and the second end cap 42 are both located on the same side of the heat exchanger core 1 in the second direction, thereby cooperating with the U-shaped second flow channel to realize the circulation of the second fluid.

[0071] like Figure 16 As shown in the figure, this is a third embodiment of the detachable reformer of this application. The detachable reformer also includes a second connecting flange 7, a third end cap 43, and a fourth end cap 44. The second connecting flange 7 is provided at the first fluid inlet and the first fluid outlet, respectively. The first fluid outlet of one heat exchanger core 1 can be connected to and communicated with the first fluid inlet of another heat exchanger core 1 through the second connecting flange 7. The first fluid inlet can be connected to the third end cap 43 through the second connecting flange 7, and the first fluid inlet can be communicated with the first fluid source through the third end cap 43. The first fluid outlet can be connected to the fourth end cap 44 through the second connecting flange 7, and the first fluid outlet can be communicated with the first fluid source through the fourth end cap 44. The first end cap 41 and the second end cap 42 are both provided on opposite sides of the heat exchanger core 1 in the second direction.

[0072] The difference between Embodiment 3 and Embodiment 2 is that the first end cap 41 and the second end cap 42 are both located on opposite sides of the heat exchanger core 1 in the second direction, that is, the first end cap 41 is located on the top and the second end cap 42 is located on the bottom. This allows for adaptive adjustment of the positions of the second fluid inlet and the second fluid outlet according to the actual space where the detachable reformer is located.

[0073] Similar to Example 1, in the three examples, such as Figure 17As shown, the second flow channel plate 12 includes a second fin 152, which includes a parallelogram portion and right-angled trapezoidal portions respectively spliced ​​on both sides of the parallelogram portion in the first direction. The parallelogram and the right-angled trapezoids on both sides are roughly spliced ​​to form a rectangle.

[0074] The parallelogram portion has grooves extending in the first direction evenly distributed on both sides of the third direction, and the right trapezoid portion has grooves extending in the second direction evenly distributed on both sides of the third direction. The grooves on the parallelogram portion and the right trapezoid portion form a Z-shaped flow channel on the second fin 152.

[0075] The parallelogram portion has a strip 14 at its edge in the second direction, and the right trapezoid portion has a strip 14 at its edge in the first direction. The strip 14 can fit between the partition 16 and the partition 16 / core cover plate 17 on both sides of the second flow channel plate 12.

[0076] Since the first end cap 41 and the second end cap 42 in Embodiment 3 are both located on opposite sides of the heat exchanger core 1 in the second direction, the second flow channel of the heat exchanger core 1 is similar to but different from that of the heat exchanger core 1 in Embodiments 1 and 2. A Z-shaped flow channel is formed on the second flow channel plate 12, so that the second fluid inlet and the second fluid outlet located on opposite sides are connected through the Z-shaped flow channel.
