Description

Technical Field

[0001] This utility model relates to the field of steam-water separator technology, and in particular to a cyclone-type anti-scaling steam-water separator. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. To obtain steam with high dryness, a steam-water separator is required in the steam system. Chinese patent CN219964227U discloses a cyclone-type anti-scaling steam-water separator, which mainly separates steam by designing a cyclone reversing pipe and cyclone blades. However, relying solely on single centrifugal separation by the outer spiral vortex can only remove larger droplets. Micron-sized fine mist in the steam cannot be captured and is directly discharged from the discharge pipe with the steam, resulting in a limited increase in steam dryness.

[0003] Therefore, it is necessary to provide a new cyclone-type anti-scaling steam-water separator to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cyclone-type anti-scaling steam-water separator.

[0005] The cyclone anti-scaling steam-water separator provided by this utility model includes a shell, on which an inlet pipe and an outlet pipe are installed. An installation ring is fixedly welded inside the shell, with the inlet pipe located below the installation ring and the outlet pipe located above the installation ring. The shell is equipped with a swirling component, which drives the steam to swirl inside the shell and separates the steam and water. A cofferdam component is also installed on the swirling component. The cofferdam component includes a lifting plate, on the bottom of which two symmetrically distributed guide rods are fixedly installed. Each guide rod has a threaded end. Several upper and lower diverter plates are fitted on the two guide rods and are staggered. Both the upper and lower diverter plates have multiple annularly distributed arc-shaped slots.

[0006] Preferably, the arc-shaped slots on the upper and lower distribution plates are staggered, and both the upper and lower distribution plates have a groove on their upper surfaces and a drain hole at the center of the plate.

[0007] Preferably, both the upper and lower distribution plates are equipped with two abutment cylinders, and both the upper and lower distribution plates are sleeved on two guide rods through the abutment cylinders.

[0008] Preferably, the swirl component includes a central tube, the outer wall of which is fixedly fitted with a spiral plate, and the top opening of the central tube is fixedly fitted with a conical bucket.

[0009] Preferably, a connecting ring is fixedly installed at the edge of the upper opening of the conical bucket, and the connecting ring is fixedly installed on the lower ring surface of the mounting ring by bolts.

[0010] Preferably, the outer ring wall of the spiral plate and the inner ring wall of the shell are spaced 2-10mm apart.

[0011] Preferably, a fixing frame is fixedly installed on the conical bucket by screws, and the lifting plate is fixedly installed on the fixing frame by bolts.

[0012] Preferably, the upper and lower distribution plates of the lower half of the guide rod are located inside the central connecting pipe, and the outer edges of the upper and lower distribution plates are spaced 2-10mm apart from the inner wall of the central connecting pipe.

[0013] Preferably, the feed pipe corresponds to the root of the conical hopper.

[0014] Preferably, a shell cover is fixedly installed on the shell by screws, and a conical lower shell is fixedly installed on the bottom of the shell by bolts. The bottom of the conical lower shell is provided with a liquid outlet, and a valve is installed on the liquid outlet.

[0015] Compared with related technologies, the cyclone-type anti-scaling steam-water separator provided by this utility model has the following beneficial effects: In this invention, when steam rises from the central connecting pipe and enters the distribution plate, several staggered upper and lower distribution plates are fitted on the guide rod. The arc-shaped grooves on the upper and lower distribution plates are misaligned, preventing most of the rising steam from flowing straight through. It must repeatedly change direction and deflect. Tiny droplets within the steam continuously impact the metal surface of the upper or lower distribution plates due to inertia, causing the steam mist to rapidly condense into large droplets. These droplets accumulate until, under gravity, the large droplets gathered in the upper or lower distribution plates can converge towards the center of the plate through the lower groove and drain downwards through the arc-shaped grooves or drain holes. This significantly enhances the steam separation effect and solves the problem of fine water mist escape in traditional equipment. Furthermore, the steam dryness is significantly improved when combined with the two-stage separation of the vortex component. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 12This utility model provides a cyclone-type anti-scaling steam-water separator, which includes a shell 1, a cyclone component 4, and a dam component 6. The shell 1 is equipped with an inlet pipe 2 and an outlet pipe 3. An installation ring 13 is fixedly welded inside the shell 1. The inlet pipe 2 is located below the installation ring 13, and the outlet pipe 3 is located above the installation ring 13. A shell cover 11 is fixedly installed on the shell 1 by screws. A conical lower shell 12 is fixedly installed at the bottom of the shell 1 by bolts. The bottom of the conical lower shell 12 is provided with a liquid outlet, and a valve is installed on the liquid outlet.

[0021] The shell 1 is equipped with a detachable conical lower shell 12 and a shell cover 11 at its upper and lower ends, which facilitates the installation and disassembly of the swirl component 4 and the cofferdam component 6, and also facilitates the maintenance of the swirl component 4 and the cofferdam component 6 in the future.

[0022] In the embodiments of this utility model, please refer to Figure 2 , Figure 3 and Figure 6 The shell 1 is equipped with a swirl component 4. The swirl component 4 drives the steam to generate swirl inside the shell 1 and perform steam-water separation. The swirl component 4 includes a central connecting pipe 41. A spiral plate 42 is fixedly installed on the outer wall of the central connecting pipe 41. A conical hopper 43 is fixedly installed at the top opening of the central connecting pipe 41. The feed pipe 2 corresponds to the root of the conical hopper 43. A connecting ring 431 is fixedly installed at the edge of the upper opening of the conical hopper 43. The connecting ring 431 is fixedly installed on the lower ring surface of the mounting ring 13 by bolts. Therefore, the conical hopper 43, together with the connecting ring 431 and the mounting ring 13, forms a closed structure.

[0023] After the swirling component 4 is installed inside the shell 1, the central connecting pipe 41, the spiral plate 42, and the chamber between the shell 1 form a spiral flow channel. Since the feed pipe 2 corresponds to the conical hopper 43, the steam entering through the feed pipe 2 can swirl downwards along the spiral flow channel. Centrifugal force is used to throw most of the droplets toward the inner wall of the shell 1 and they fall, completing the initial and efficient steam separation. When some steam reaches the end of the central connecting pipe 41, the water falls to the lower conical shell 12 under its own weight, while the steam floats up and enters the central connecting pipe 41 (e.g., ...). Figure 3 (As shown).

[0024] In an optional solution, to reduce the sinking of some steam, technicians can install a separator plate at the connection between the shell 1 and the conical lower shell 12 as needed, thereby deflecting the steam and causing it to float upward.

[0025] In an optional configuration, a gap of 2-10mm is left between the outer ring wall of the spiral plate 42 and the inner ring wall of the housing 1. This reduces the friction between the spiral plate 42 and the housing 1 when the swirling component 4 is installed inside the housing 1. On the other hand, it can drive the liquid thrown onto the inner wall of the housing 1 to flow downward along the gap between the outer ring wall of the spiral plate 42 and the inner ring wall of the housing 1.

[0026] In the embodiments of this utility model, please refer to Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 A dam component 6 is installed on the swirl component 4. The dam component 6 includes a lifting plate 61. A fixing frame 5 is fixedly installed on the conical bucket 43 by screws. The lifting plate 61 is fixedly installed on the fixing frame 5 by bolts. Two symmetrically distributed guide rods 62 are fixedly installed at the bottom of the lifting plate 61. Each guide rod 62 has a threaded part 63 at its end. Several upper diverter plates 64 and lower diverter plates 65 are sleeved on the two guide rods 62. The upper distribution plate 64 and the lower distribution plate 65 are staggered. Both the upper distribution plate 64 and the lower distribution plate 65 have multiple annular arc-shaped slots 6b. The arc-shaped slots 6b on the upper distribution plate 64 and the lower distribution plate 65 are staggered. The upper surface of the upper distribution plate 64 and the lower distribution plate 65 are provided with a lower groove 6c and a drain hole is provided at the center of the plate. The lower half of the guide rod 62, the upper distribution plate 64 and the lower distribution plate 65 are located inside the central connecting pipe 41.

[0027] When steam rises from the central connecting pipe 41 and enters the distribution plate, several staggered upper distribution plate 64 and lower distribution plate 65 are fitted on the guide rod 62, and the arc-shaped slots 6b on the upper distribution plate 64 and lower distribution plate 65 are misaligned. Therefore, most of the rising steam cannot pass through in a straight line when flowing upward, and must repeatedly change direction and deflect. The tiny droplets in the steam continuously collide with the metal surface of the upper distribution plate 64 or lower distribution plate 65 under the action of inertia. The mist in the steam quickly condenses into large droplets, and they accumulate more and more. Finally, under the action of gravity, the large droplets accumulated in the upper distribution plate 64 or lower distribution plate 65 can be gathered towards the center of the plate through the lower groove 6c, and discharged downward through the arc-shaped slot 6b or the drain hole. This greatly enhances the steam separation effect and solves the problem of fine water mist escape in traditional equipment. In addition, the steam dryness is significantly improved when combined with the two-stage separation of the swirl component 4.

[0028] In an optional configuration, a 2-10mm gap is left between the outer edge of the upper and lower distribution plates 64 and the inner wall of the central connecting pipe 41, making it easy to insert the upper and lower distribution plates 64 and 65 into the central connecting pipe 41.

[0029] In an optional configuration, two abutment cylinders 6a are installed on both the upper diversion plate 64 and the lower diversion plate 65, and both the upper diversion plate 64 and the lower diversion plate 65 are fitted onto the two guide rods 62 via the abutment cylinders 6a. When assembling the cofferdam component 6, after inverting the hoisting plate 61, the two abutment cylinders 6a on the upper diversion plate 64 are fitted onto the two guide rods 62, and then the two abutment cylinders 6a on the lower diversion plate 65 are fitted onto the two guide rods 62. At this point, the two abutment cylinders 6a of the lower diversion plate 65 abut against the bottom of the upper diversion plate 64. Then, the above method is repeated to install an appropriate number of upper diversion plates 64 and lower diversion plates 65. After the upper diversion plates 64 and lower diversion plates 65 are installed, nuts are installed on the threaded portion 63 and tightened to ensure that the upper diversion plates 64 and lower diversion plates 65 installed on the guide rods 62 are tightly abutted (e.g., Figure 8 (As shown); since both the upper diversion plate 64 and the lower diversion plate 65 are single-piece structures, and the cofferdam component 6 is mounted on the conical bucket 43 via the fixing frame 5, the cofferdam component 6 can be removed from the conical bucket 43 for maintenance. If a diversion plate is damaged, it can be removed and replaced. Furthermore, it can be pre-installed on the conical bucket 43 before installing the swirl component 4 into the housing 1, reducing the operation of installation inside the housing 1.

[0030] In addition, according to actual needs, a chemical atomizing nozzle, as described in the patent with publication number CN219964227U, can be added to this application. The external boiler anti-scaling agent is connected to the chemical atomizing nozzle through an external high-pressure water pump and sprayed out through the chemical atomizing nozzle. The atomized anti-scaling agent moves in a swirling motion with the steam, so that it can fully contact the inner wall of the shell 1. Through chemical reaction, it can effectively prevent and remove scale and extend the service life of the equipment.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
