Description

Technical Field

[0001] This utility model relates to the field of mixer device technology, and in particular to a mixer for saturated steam condensate and subcooled water. Background Technology

[0002] In industrial production, the mixing process of saturated steam condensate and subcooled water often faces the problem of steam hammer. Saturated steam condensate is prone to forming a gas-liquid mixture during pipeline transportation. When it is directly mixed with subcooled water, the steam bubbles in the condensate burst due to sudden cooling, causing a sharp contraction in volume and triggering severe pressure fluctuations and pipeline vibrations, known as the "steam hammer effect." This effect can lead to pipe weld tearing, displacement, and even equipment damage, potentially seriously threatening the safe operation of the system.

[0003] In existing technologies, water hammer devices and other equipment absorb vibration energy through buffer spaces, but this can only alleviate the water hammer effect during continuous mixing and cannot fundamentally solve the core problem of concentrated bubble rupture. Their buffer spaces are limited and they are not designed with special structures for the dispersion and gradual cooling of bubbles, making it difficult to eliminate the risk of water hammer when saturated steam condensate mixes with subcooled water. This may lead to insufficient pipeline operation safety and high maintenance costs. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art by providing a mixer for saturated steam condensate and subcooled water.

[0007] shell;

[0008] A first pipe and a second pipe are fixedly connected to both sides of the outer shell. The first pipe and the second pipe are symmetrically arranged. A water inlet pipe is fixedly connected to the outer shell.

[0009] A mounting plate is fixedly connected to the outer casing, and multiple sets of heat exchange tubes are fixedly connected to the mounting plate.

[0010] The outer shell is detachably connected to a distribution section, which includes a first distribution plate and a second distribution plate. The first distribution plate and the second distribution plate are fixedly connected, and both the first distribution plate and the second distribution plate are provided with distribution holes.

[0011] Preferably, the first pipe body is provided with an installation groove, and a fixing plate is slidably connected in the installation groove, the fixing plate being fixedly connected to the first distribution plate.

[0012] Furthermore, a first magnet is fixedly connected in the mounting groove, and the fixing plate is a magnetic plate, wherein the first magnet is attracted to the fixing plate.

[0013] Furthermore, the fixing plate is a trapezoidal plate.

[0014] Preferably, a first reinforcing rod is fixedly connected to the side wall of the first distribution plate, and the first reinforcing rod is connected to the side wall of the first tube.

[0015] Furthermore, a second magnet is fixedly connected inside the first tube, the first reinforcing rod is an iron rod, and the second magnet and the first reinforcing rod are attracted to each other.

[0018] 1.

Combined with the gradual cooling design of the heat exchange tubes, this allows the bubbles to burst slowly and in batches within the tubes, dispersing and releasing energy, thus avoiding the violent vibrations caused by concentrated bursting. The final mixed fluid is discharged as bubble-free subcooled water, fundamentally eliminating the steam hammer effect, significantly reducing the risk of pipe weld tearing and displacement, and ensuring safe system operation.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1:

[0027] Reference Figures 1-5 A mixer for saturated steam condensate and subcooled water, comprising:

[0028] Outer shell 1;

[0029] A first pipe body 101 and a second pipe body 102 are fixedly connected to both sides of the outer shell 1. The first pipe body 101 and the second pipe body 102 are symmetrically arranged. A water inlet pipe 2 is fixedly connected to the outer shell 1.

[0030] A mounting plate 3 is fixedly connected to the outer casing 1, and multiple sets of heat exchange tubes 301 are fixedly connected to the mounting plate 3.

[0031] The outer casing 1 is detachably connected to a distribution section, which includes a first distribution plate 4 and a second distribution plate 6. The first distribution plate 4 and the second distribution plate 6 are fixedly connected, and both the first distribution plate 4 and the second distribution plate 6 are provided with distribution holes 403.

[0032] In use, saturated steam condensate enters the outer shell 1 from the first tube 101. The large bubbles generated during the transport of the saturated steam condensate are broken into smaller bubbles by the distribution section with small holes in the first tube 101 and then distributed into the heat exchange tube 301 in the mixer. Subcooled water enters the outer shell 1 through the water inlet pipe 2 and does not come into direct contact with the saturated steam condensate containing small bubbles. The subcooled water is transported and cooled by passing through the heat exchange tube 301. Finally, after mixing with the saturated steam condensate at the end of the tube, it is discharged from the mixer from the second tube 102 in the form of subcooled water that cannot flash out bubbles.

[0033] In this application, the saturated steam condensate is gradually cooled from the tube inlet to the tube outlet, and the temperature gradually decreases. The dispersed fine steam drum gradually breaks down, which disperses and weakens the steam hammer effect, reducing the pipeline vibration to an acceptable range or even eliminating the vibration. This eliminates the risk of steam hammer caused by the mixing of saturated steam condensate and subcooled water, and achieves safe mixing and transportation.

[0034] An installation groove 5 is provided on the first tube body 101, and a fixing plate 402 is slidably connected in the installation groove 5. The fixing plate 402 is fixedly connected to the first distribution plate 4.

[0035] A first magnet 501 is fixedly connected in the mounting slot 5, and the fixing plate 402 is a magnetic plate. The first magnet 501 is attracted to the fixing plate 402.

[0036] Reference Figure 4 The first magnet 501 attracts the fixing plate 402, thereby effectively adsorbing the fixing plate 402 and thus effectively improving the installation stability of the fixing plate 402.

[0037] It should be noted that both the first magnet 501 and the second magnet 1011 are commercially available strong magnets.

[0038] By making the first distribution plate 4 detachable, it is easier to replace and maintain the distribution section, ensuring that the distribution section can stably divide the large bubbles generated in the saturated steam condensate into fine bubbles and redistribute them into the heat exchange tube 301 in the mixer.

[0039] The fixing plate 402 is a trapezoidal plate.

[0040] Reference Figure 4 By setting the fixing plate 402 as a trapezoidal plate, the stability of the fixing plate 402 in the mounting groove 5 can be effectively guaranteed, and the sliding of the fixing plate 402 during use can be reduced.

[0041] A first reinforcing rod 401 is fixedly connected to the side wall of the first distribution plate 4, and the first reinforcing rod 401 is connected to the side wall of the first tube 101.

[0042] A second magnet 1011 is fixedly connected in the first tube 101. The first reinforcing rod 401 is an iron rod. The second magnet 1011 and the first reinforcing rod 401 attract each other.

[0043] Reference Figure 4 , Figure 5 During installation, when the first magnet 501 attracts the fixing plate 402, the first reinforcing rod 401 slides directly below the second magnet 1011. At this time, the first reinforcing rod 401 and the second magnet 1011 attract each other. The attraction between the first reinforcing rod 401 and the second magnet 1011 further improves the installation stability of the first distribution plate 4.

[0044] A second reinforcing rod 601 is fixedly connected to the side wall of the second distribution plate 6, and the second reinforcing rod 601 is fixedly connected to the first distribution plate 4.

[0045] Reference Figure 4By setting multiple sets of second reinforcing rods 601 on the second distribution plate 6, the connection strength between the second distribution plate 6 and the first distribution plate 4 can be improved, thereby ensuring the stability of the second distribution plate 6 in use.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
