Description

Technical Field

[0001] This application relates to the field of steam-water separation, specifically to a multi-stage separation dual-cyclone steam-water separator. Background Technology

[0002] A cyclone steam-water separator is a device that uses centrifugal force to separate suspended droplets in steam. Steam and water are introduced along the tangential direction of the tank, and then the airflow is guided by internal baffles to make a downward high-speed spiral motion. The centrifugal force generated causes the heavier droplets in the steam to move towards the side wall of the tank until the droplets contact the side wall of the tank, accumulate, and flow downward to the bottom of the tank for centralized discharge. The relatively dry steam is discharged upward through the exhaust pipe.

[0003] Chinese patent document CN218901148U discloses a composite cyclone steam-water separator, specifically disclosing the shell, which has an inlet on the left and an outlet on the right. Inside the shell is a cyclone tube, and on the right side of the cyclone tube is a baffle tube connected to the outlet. Inside the cyclone tube is a fixed rod with a spiral baffle on it. A baffle plate is located on the lower side of the cyclone tube. The baffle plate has a structure with a raised center and downward slope around the edges, and water holes are provided on the baffle plate. This design solves the technical problem of insufficient steam-water separation in existing equipment.

[0004] However, the aforementioned patent only includes a shell and a corresponding steam-water separation device, resulting in poor overall separation performance. Furthermore, the separated water is not filtered quickly and effectively, increasing the difficulty of subsequent operations. Utility Model Content

The drain pipe of the first cyclone separator is connected to the housing, and the drain pipe of the second cyclone separator is connected to the housing.

[0010] Optionally, the top of the housing is provided with an opening, the filter unit is disposed inside the housing through the opening, and the bottom of the housing is provided with a hydraulic cylinder, which is used to push the filter unit out above the opening.

One end of each support column is connected to the top plate, and the other end of each support column is connected to the bottom plate. The push rod of the hydraulic cylinder is connected to the bottom of the bottom plate.

[0012] The four filter screens are arranged sequentially between the top plate and the bottom plate, forming a filter cavity with the top plate and the bottom plate, and the collecting pipe is connected to the filter cavity.

Detailed Implementation

[0025] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] like Figure 1-4As shown, the multi-stage dual-cyclone steam-water separator includes a first cyclone separator 1, a second cyclone separator 2, and a filtration mechanism. Both the first cyclone separator 1 and the second cyclone separator 2 are equipped with an inlet pipe 11, an exhaust pipe 12, and a drain pipe 13. The exhaust pipe 12 of the first cyclone separator 1 is connected to the inlet pipe 11 of the second cyclone separator 2 via a connecting pipe 3, and the height of the exhaust pipe 12 of the first cyclone separator 1 is higher than the height of the inlet pipe 11 of the second cyclone separator 2. The drain pipes 13 of both the first cyclone separator 1 and the second cyclone separator 2 are connected to the filtration mechanism. In this way, the steam and water to be separated can undergo two cyclone separations, improving the separation effect and allowing for filtration of the separated water to remove impurities and reduce the difficulty of subsequent operations. Specifically, the first cyclone separator 1 and the second cyclone separator 2 are the core components for achieving steam-water separation. The first cyclone separator 1 and the second cyclone separator 2 typically adopt a cylindrical tank shape, which is conducive to the formation of a stable rotating airflow within the steam and water. The feed pipe 11 is used to introduce the steam-water mixture into the cyclone separator. The feed pipe 11 is typically positioned tangentially to the tank body, allowing the steam and water to quickly form a rotating airflow upon entry. The exhaust pipe 12 is used to discharge relatively dry gas and is generally located at the top of the tank body. The drain pipe 13 is used to discharge the separated water and is typically located at the bottom of the tank body. The feed pipe 11, exhaust pipe 12, and drain pipe 13 are generally welded to the tank body to ensure a tight seal. The connecting pipe 3 connects the exhaust pipe 12 of the first cyclone separator 1 to the feed pipe 11 of the second cyclone separator 2. One end of the connecting pipe 3 is connected to the exhaust pipe 12 of the first cyclone separator 1, and the other end is connected to the feed pipe 11 of the second cyclone separator 2 via flanges 30. This connection method facilitates installation and disassembly and ensures a tight seal. Furthermore, to improve the secondary separation effect, a booster pump can be installed on the connecting pipe 3 to increase the material velocity entering the second cyclone separator 2.

[0027] The filtration mechanism includes a housing 4 and a filter unit 5 disposed within the housing 4. The drain pipe 13 of the first cyclone separator 1 is connected to the housing 4, and the drain pipe 13 of the second cyclone separator 2 is also connected to the housing 4. The filter unit 5 is disposed within the housing 4 and located between the two drain pipes 13. A collecting pipe 6 is provided on the filter unit 5 for discharging the filtered water. The filter unit 5 includes a top plate 51, a bottom plate 52, support columns 53, and a filter screen 54. Four support columns 53 are respectively and correspondingly disposed at the four corners of the top of the bottom plate 52. One end of each support column 53 is connected to the top plate 51, and the other end is connected to the bottom plate 52. The top plate 51 and the bottom plate 52 serve to fix the support columns 53 and the filter screen 54. The support columns 53 are fitted against the inner wall of the opening 41, providing a mounting base for the filter screen 54. Four filter screens 54 are arranged sequentially between the top plate 51 and the bottom plate 52, forming a filter cavity with the top plate 51 and the bottom plate 52, and the collecting pipe 6 is connected to the filter cavity.

[0028] Each of the two side walls of the support column 53 is provided with an mounting strip 530, and each filter screen 54 can be detachably installed on the two mounting strips 530 of the two adjacent support columns 53. The bottom plate 52 is located inside the housing 4 and can cover the opening 41 at the top of the housing 4, and the top plate 51 is located outside the housing 4 and can cover the opening 41. The top of the bottom plate 52 is also provided with a protruding plate 521, which is an integral structure with the bottom plate 52, and a stepped surface is formed between the protruding plate 521 and the bottom plate 52. The support column 53 is installed on the top of the protruding plate 521, and a sealing ring 522 is provided around the stepped surface. The protruding plate 521 can be inserted into the inside of the opening 41, and the sealing ring 522 abuts against the outside of the opening 41. This structural arrangement ensures the sealing between the filter unit 5 and the housing 4, preventing the leakage of unfiltered water.

[0029] A hydraulic cylinder 42 is provided at the bottom of the housing 4. The hydraulic cylinder 42 is used to push the filter unit 5 above the opening 41. When it is necessary to replace or clean the filter unit 5, the hydraulic cylinder 42 is activated to push the filter unit 5 out. The operation is convenient and quick. At the same time, after the hydraulic cylinder 42 pushes the filter unit 5 up, the convex plate 521 can enter into the opening 41 and block the opening 41. The bottom plate 52 covers the outside of the opening 41 and keeps the sealing ring 522 in a compressed state, thereby ensuring that the bottom plate 52 can reliably seal the opening 41. In this way, no water will leak from the opening 41 during the replacement of the filter screen 54.

[0030] The implementation principle of this embodiment is as follows: The material first enters the first cyclone separator 1 through the feed pipe 11 for initial separation. The separated water is discharged to the filtration mechanism through the drain pipe 13, while the gas still containing water is discharged through the exhaust pipe 12. The discharged gas enters the feed pipe 11 of the second cyclone separator 2 through the connecting pipe 3, where it undergoes cyclone separation again to further improve the dryness of the gas. The separated water is also discharged to the filtration mechanism through the drain pipe 13. In the filtration mechanism, after the water enters the housing 4, it is filtered by the filter unit 5, where impurities are intercepted on the filter screen 54. The filtered water is discharged through the collection pipe 6. When it is necessary to replace or clean the filter unit 5, the hydraulic cylinder 42 is activated to push the filter unit 5 out, which facilitates operation and effectively filters impurities in the water, reducing the difficulty of subsequent operations and improving the efficiency and quality of the entire production process.

[0031] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
