Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically a two-stage plate condenser for low-pressure steam. Background Technology

[0002] In industrial applications, low-pressure steam condensation is frequently encountered, such as secondary steam condensation during material depressurization evaporation and condensation of negative-pressure exhaust steam. Negative-pressure steam condensation is characterized by low temperature, large specific volume, and small condensation load. When using conventional plate condensers, the cooling water volume determined based on the condensation heat load is insufficient to guarantee the inter-plate flow velocity on the cooling water side, and its value is often far lower than the normal inter-plate water velocity requirement.

[0003] In existing technology, a connecting pipe is used to connect the water outlet pipe at the top of the plate to the water inlet pipe at the bottom. This allows steam to quickly come into contact with the cooling water after entering the plate, thus condensing into water droplets for heat dissipation.

[0004] However, in actual use, since plate condensers are assembled from multiple plates, they can dissipate heat better. But since the condensing device is made of multiple welded plates, placing it directly on the ground or workbench will reduce its heat dissipation area, thus affecting the condenser's heat dissipation effect.

This solves the problem that, in practical use, while plate condensers are assembled from multiple plates, which improves heat dissipation, placing the condensing device directly on the ground or workbench reduces its heat dissipation area, thus affecting the condenser's heat dissipation effect.

[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] In practical use, plate condensers are assembled from multiple plates, which improves their heat dissipation. However, since the condensing unit is made up of multiple welded plates, placing it directly on the ground or workbench will reduce its heat dissipation area, thus affecting the condenser's heat dissipation effect.

[0023] In view of this, the present invention provides a two-stage plate condenser for low-pressure steam, which solves the problem that in actual use, since the plate condenser is assembled from multiple plates, which can improve its heat dissipation effect, the condensing device is welded from multiple plates and placed directly on the ground or workbench, which will reduce its heat dissipation area and thus affect the heat dissipation effect of the condenser.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0025] Example 1: By Figure 1-5 It is known that a two-stage low-pressure steam plate condenser includes plates 1, with an inlet pipe 5 opened on one side of the outer wall of the plates 1. The two-stage low-pressure steam plate condenser also includes a support device 2, a connecting device 3, and a fixing device 4. The support device 2 is installed at the bottom of the plates 1; the connecting device 3 is installed on the outer wall of the plates 1; and the fixing device 4 is located above the support device 2 and installed on the outer wall of the plates 1. The support device 2 supports the plates 1, the connecting device 3 enables the condensate in the plates 1 to be circulated, and the fixing device 4 fixes multiple plates 1 together.

[0026] In the specific implementation process, it is worth noting that an air inlet pipe 5 is connected to the outer wall of the plate 1, through which steam is transported into the plate 1. The plates 1 are fixed together by welding, and a fixing device 4 is used to fix the plates 1 to prevent multiple plates 1 from loosening due to long-term placement. A support device 2 is used to support the plates 1 to prevent the plates 1 from being too close to the ground, which would reduce their heat dissipation effect.

[0027] Furthermore, the support device 2 includes a base 21, a mounting plate 22, a protective pad 23, a support plate 24, and a clamping structure 25. The base 21 is located below the plate 1. Two sets of mounting plates 22 are provided, respectively located on both sides of the plate 1, and their bottoms are fixedly connected to the top of the base 21. The protective pad 23 is fixedly connected to the side of the mounting plate 22 near the plate 1 and abuts against the outer wall of the plate 1. The support plate 24 abuts against the bottom of the plate 1 and is fixedly connected to the outer wall of the mounting plate 22. The clamping structure 25 is installed on the outer wall of the mounting plate 22. Through the cooperation of the base 21 and the mounting plate 22, the protective pad 23 and the support plate 24 support and fix the plate 1, and the clamping structure 25 can clamp the plate 1.

[0028] In the specific implementation process, it is worth noting that the protective pad 23 is used to separate the mounting plate 22 and the plate 1 to avoid excessive pressure on the plate 1 caused by the mounting plate 22, which could damage the plate 1. Moreover, the protective pad 23 is made of rubber and has a certain degree of extensibility, which allows the plate 1 to have close contact with the mounting plate 22. Furthermore, the support plate 24 is used to increase the distance between the plate 1 and the base 21. In this way, the heat dissipation area of ​​the plate 1 does not change, and it can also accelerate the heat dissipation of the plate 1 under the action of air flow.

[0029] Furthermore, the clamping structure 25 includes a baffle 251 and a locking block 252. The baffle 251 is provided in two sets, which abut against the outer wall of the plate 1 at the front and back respectively. The locking block 252 is fixedly connected to the outer wall of the mounting plate 22, and its inner wall is sleeved on the outer wall of the baffle 251. The plate 1 is fixed in the middle of the support device 2 through the cooperation of the baffle 251 and the locking block 252.

[0030] In the specific implementation process, it is worth noting that baffles 251 are placed at the front and back of plate 1, and locking blocks 252 are attached to both ends of baffles 251. The locking blocks 252 are used to fix the baffles 251 to the outer wall of the mounting plate 22, so that plate 1 is stable when it is placed.

[0031] Specifically, when using this two-stage low-pressure steam plate condenser, when placing plate 1, plate 1 is placed on top of support plate 24, and both sides of plate 1 are pressed against the outer wall of protective pad 23. After placement, baffle 251 is inserted into the clip 252 on the outer wall of mounting plate 22 to fix baffle 251 to the front and back of plate 1. This makes the placement of plate 1 more stable, and the heat dissipation area of ​​the condensing device under support will not change. The condensate in the condensing device is circulated through the connecting device 3, and the fixing device 4 ensures that the plates 1 are stable during long-term placement and will not be damaged.

[0032] Example 2: From Figure 1-5It is understood that the connecting device 3 includes an inlet pipe 31, an outlet pipe 32, a connecting pipe 33, a fixing shell 34, and a sealing gasket 35. Two sets of inlet pipes 31 are provided, respectively located on the lower sides of the outer wall of the plate 1; two sets of outlet pipes 32 are provided, respectively located on the upper sides of the outer wall of the plate 1; the connecting pipe 33 connects the inlet pipe 31 located on one side below and the outlet pipe 32 located on the other side above; the fixing shell 34 is fitted onto the outer wall of the connecting pipe 33, and its inner wall is threaded to the outer walls of the inlet pipe 31 and the outlet pipe 32; two sets of sealing gaskets 35 are provided, respectively fitted onto the outer walls of the inlet pipe 31 and the outlet pipe 32, and their outer walls abut against the inner wall of the fixing shell 34; wherein, through the cooperation of the fixing shell 34 and the connecting pipe 33, the inlet pipe 31 and the outlet pipe 32 are connected together, and the sealing gasket 35 can seal the gaps inside the fixing shell 34;

[0033] In the specific implementation process, it is worth noting that there are two sets of water outlet pipe 32 and water inlet pipe 31. Each set of water outlet pipe 32 and water inlet pipe 31 is connected together by connecting pipe 33. When the steam entering the condenser condenses into water, it will flow back to plate 1 through connecting pipe 33, so that the condensate comes into contact with the steam and is recycled. When installing connecting pipe 33, sealing gasket 35 is put on the outer wall of water inlet pipe 31 and water outlet pipe 32, and the fixing shell 34 on the outer wall of connecting pipe 33 is rotated so that the inner wall of fixing shell 34 is pressed against the outer wall of sealing gasket 35, thereby making the fixing shell 34 more tightly connected to water inlet pipe 31 and water outlet pipe 32.

[0034] Furthermore, the fixing device 4 includes an extrusion plate 41, a limiting block 42, a connecting rod 43, an insert block 44, and a clamping structure 45. Two extrusion plates 41 are provided, which are respectively pressed against the two sides of the outer wall of the plate 1; the limiting block 42 is fixedly connected to the outer wall of the extrusion plate 41; the connecting rod 43 is installed between the limiting blocks 42; two insert blocks 44 are provided, which are respectively fixedly connected to the two ends of the connecting rod 43 and respectively inserted into the outer wall of the two limiting blocks 42; the clamping structure 45 is installed on the outer wall of the insert block 44; wherein, through the cooperation of the insert block 44 and the connecting rod 43, the limiting block 42 and the extrusion plate 41 are installed on the outer wall of the plate 1, and the clamping structure 45 can clamp the limiting block 42 and the insert block 44.

[0035] In the specific implementation process, it is worth noting that the outer wall of the limiting block 42 is provided with an insertion hole that can fit with the surface of the insertion block 44. This makes the connection between the connecting rod 43 and the insertion block 44 more stable, and the cooperation between the connecting rod 43 and the pressing plate 41 makes the multiple plates 1 more stable.

[0036] Furthermore, the clamping structure 45 includes a locking pin 451 and a bolt 452. The locking pin 451 is fixedly connected to the outer wall of the insert block 44 and inserted into the outer wall of the limiting block 42; the bolt 452 is threadedly connected to the inner wall of the locking pin 451; wherein, through the cooperation of the locking pin 451 and the bolt 452, the insert block 44 is fixed to the outer wall of the limiting block 42.

[0037] In the specific implementation process, it is worth noting that a threaded groove is provided on the inner wall of the locking pin 451, and the inner wall of the threaded groove is open, with the opening narrowing from the outside to the inside. In this way, after the bolt 452 is inserted into the inside of the locking pin 451, the outer wall of the locking pin 451 will be pressed against the inner wall of the limiting block 42, so that the connecting rod 43 can be fixed on the outer wall of the limiting block 42, and the pressing plate 41 can fix the plate 1.

[0038] Specifically, based on the above embodiments, the plate 1 is installed on the top support of the support device 2, the extrusion plate 41 is placed on the outer wall of the plate 1, the insert block 44 on the outer wall of the connecting rod 43 is inserted into the outer wall of the limiting block 42, and the bolt 452 is inserted into the inner wall of the locking pin 451, connecting the connecting rod 43 and the extrusion plate 41 together, so that the multiple plates 1 are stable after connection.
