Description

Technical Field

[0001] This utility model belongs to the technical field of steam-water separators, specifically, it relates to a vertical self-circulating spray filtration three-stage steam-water separator. Background Technology

[0002] In industrial production, vacuum pump systems often require gas-liquid separators for efficient separation of the gas-liquid mixture to ensure stable equipment operation and extend service life. Traditional gas-liquid separators typically employ a two-stage separation structure: the primary separator removes large particulate impurities from the mixed gas through gravity or inertia, while the secondary separator further separates small particulate impurities and liquid components, ultimately outputting clean gas. However, current technologies generally face the dual technical bottlenecks of residual foam at the outlet and insufficient gas dryness. These problems not only lead to decreased separation efficiency but may also trigger a chain reaction, including corrosion of downstream equipment, fluctuations in process parameters, and increased environmental impact.

[0003] A Chinese patent application with application number CN202410215943.X discloses a steam-water separator, comprising: a main body including a shell, an air inlet connector, and an air outlet pipe; a first opening at the bottom of the shell; the air inlet connector being tangentially mounted on the surface of the shell; the air outlet pipe being located inside the shell and extending upwards beyond the top of the shell, forming a separation chamber between the air outlet pipe and the shell; a water storage body with a second opening at its top, detachably connected to the main body, and the water storage body sealing the area below the first opening; a connecting body including a retaining ring and a hollow supporting part; the retaining ring having a through hole; the outer wall of the retaining ring being mounted on the second opening; and the inner wall of the retaining ring being integrally formed with the bottom end of the supporting part; and a separating body including a hollow rotating part and blades disposed on the outer periphery of the rotating part; the bottom of the rotating part being rotatably mounted on the supporting part; and the top of the rotating part being sleeved on the outer periphery of the air outlet pipe. This steam-water separator achieves two-stage steam-water separation, improving separation efficiency.

[0004] However, the application only achieves two-stage gas-water separation, and does not address the issues of foaming during separation and gas drying, which affect the cleanliness of the gas after separation. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide a vertical self-circulating spray filter three-stage steam-water separator with a simple overall structure, capable of three-stage separation of steam and water, small footprint, effectively solving the problems of foam generation and gas drying during the separation process, and improving the cleanliness of the separated gas.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A vertical self-circulating spray filter three-stage air-water separator includes a tank, a motor fixedly installed at the upper end of the tank, a defoaming device driven by the motor installed inside the tank near the motor, a demister fixedly installed inside the tank above the defoaming device, a baffle assembly installed inside the tank near the bottom, and a spraying device installed outside the tank. The input end of the spraying device is connected to the bottom of the tank, and the output end of the spraying device extends to the inside of the tank near the defoaming device.

[0008] The following are further optimizations of the above technical solution by this utility model:

[0009] An air outlet is provided at the upper end of the tank near the edge, a spiral guide plate is fixedly installed in the middle of the tank, and an air inlet is provided on the side wall of the tank, located below the spiral guide plate.

[0010] Further optimization: An observation window is provided on the side wall of the tank near the air inlet, a bottom drain outlet is provided at the bottom of the tank, a side drain outlet is also provided on the side wall of the tank, and a water inlet valve is connected to the side wall of the tank below the baffle assembly.

[0011] Further optimization: The defoaming device includes a rotating shaft fixedly installed on the power output end of the motor, and a defoaming net is fixedly installed at the end of the rotating shaft away from the motor.

[0012] Further optimization: Multiple protrusions are evenly and vertically arranged on the side of the defoaming net away from the rotating shaft, and a sealing strip is fixedly installed on the outer surface of the defoaming net.

[0013] Further optimization: The spraying device includes a self-circulating water outlet valve, and the other end of the self-circulating water outlet valve is connected to a filter device through a pipeline.

[0014] Further optimization: The output end of the filtration device is connected to a filtrate pump, the other end of the filtrate pump is connected to a water pipe, the other end of the water pipe is connected to a spray pipe, and the spray pipe is located inside the tank between the defoaming net and the spiral guide plate.

First, impurities are initially separated by a spiral guide plate, then impurities in the gas are separated by a spray device, and finally foam in the water vapor is eliminated by a defoaming device to prevent water molecules from escaping the gas mixture. Then, the gas is dried by a demister to further ensure the cleanliness of the gas. Not only is the gas clean, but the spray device also uses water circulation, which largely avoids the waste of water resources, reduces the overall volume of the gas-water separator, occupies a small area, and improves application.

[0023] like Figure 1-3 As shown: A vertical self-circulating spray filter three-stage air-water separator includes a tank 1. A motor 2 is fixedly installed at the upper end of the tank 1. A defoaming device 3 driven by the motor 2 is installed inside the tank 1 near the position of the motor 2. A demister 4 is also fixedly installed inside the tank 1 above the defoaming device 3. A baffle assembly 7 is installed inside the tank 1 near the bottom. A spraying device 5 is also installed outside the tank 1. The input end of the spraying device 5 is connected to the bottom of the tank 1, and the output end of the spraying device 5 extends to the inside of the tank 1 near the position of the defoaming device 3.

[0024] In this embodiment, the tank 1 is used on the ground by setting support legs. The installation method of the support legs is well known and will not be described in detail here.

[0025] An air outlet 11 is provided at the upper end of the tank 1 near the edge, and the separated clean gas is output from the air outlet 11.

[0026] A spiral guide plate 6 is fixedly installed in the middle of the inside of the tank 1. The function of the spiral guide plate 6 is to assist the gas mixture entering the tank 1 to rotate downward along the rotation direction of the spiral guide plate 6. The gas mixture is initially separated from the liquid and impurities in the gas mixture by its own gravity and the downward rotation force.

[0027] The specific shape and installation method of the spiral guide plate 6 are well known in the prior art and will not be described in detail here.

[0028] An air inlet 16 is provided on the side wall of the tank body 1. The air inlet 16 is located below the spiral guide plate 6. This design allows the gas mixture entering from the air inlet 16 to rotate downwards along the spiral guide plate 6, which is conducive to the initial separation of gas, liquid and impurities.

[0029] An observation window 12 is provided on the side wall of the tank 1 near the air inlet 16, through which the interior of the tank 1 can be observed in real time.

[0030] The bottom of the tank 1 is provided with a bottom drain outlet 14, and a control valve is provided on the bottom drain outlet 14 (not shown in the figure). During the operation of the separator, the control valve is closed to prevent the spray water of the spray device 5 from flowing away. When the separator is finished, the sewage in the tank 1 is discharged from the bottom drain outlet 14, which is convenient to operate.

[0031] The tank body 1 is also provided with a side drain outlet 13, which is located above the baffle assembly 7.

[0032] A water inlet valve 15 is connected to the side wall of the tank body 1 below the baffle assembly 7. The water inlet valve 15 is connected to an external water source through a pipeline. The water required by the spray device 5 enters the bottom of the tank body 1 through the water inlet valve 15, which is convenient to operate.

[0033] The defoaming device 3 includes a rotating shaft 31 fixedly installed on the power output end of the motor 2.

[0034] A defoaming net 32 ​​is fixedly installed at the end of the rotating shaft 31 away from the motor 2. In this embodiment, the defoaming net 32 ​​is made of stainless steel mesh with square mesh openings. The mesh openings are set to square holes of 1.2 x 1.2 mm, which can eliminate some foam.

[0035] The defoaming net 32 ​​has a plurality of protrusions 33 evenly and vertically arranged on the side away from the rotating shaft 31. When the motor 2 is started, it drives the defoaming net 32 ​​to rotate, and then the plurality of protrusions 33 rotate. When the foam comes into contact with the rotating protrusions 33, it can be eliminated, thereby improving the efficiency of foam elimination.

[0036] A sealing strip 34 is fixedly installed on the outer surface of the defoaming net 32. The sealing strip 34 is in close contact with the inner wall of the tank 1. When the defoaming net 32 ​​rotates, the sealing strip 34 plays a sealing role to prevent the unseparated gas mixture from overflowing from the edge of the defoaming net 32.

[0037] The demister 4 is commercially available and, through its interception function, further separates impurities in the gas, making the discharged gas cleaner.

[0038] The spraying device 5 includes a self-circulating water outlet valve 51, which is connected to the bottom of the tank 1 and corresponds to the position of the water inlet valve 15.

[0039] The other end of the self-circulating water outlet valve 51 is connected to a filter device 55 via a pipeline. In this embodiment, the filter device 55 is made of multi-layer adsorption filter cotton, which can be obtained commercially. The specific filtration principle is well known and will not be described in detail here.

[0040] The output end of the filter device 55 is connected to the filtrate pump 52, the other end of the filtrate pump 52 is connected to the water pipe 53, the other end of the water pipe 53 is connected to the spray pipe 54, and the spray pipe 54 is located inside the tank 1 between the defoaming net 32 ​​and the spiral guide plate 6.

[0041] In this embodiment, both the filtrate pump 52 and the spray pipe 54 are commercially available. The filtrate pump 52 can pump the water at the bottom of the tank 1 through the filter device 55 and then pump it upwards to the spray pipe 54 to spray the gas mixture, further filtering impurities in the gas and forming a cycle, thus saving water resources.

[0042] The baffle assembly 7 includes a baffle 71 fixedly installed inside the tank 1 near the bottom. The baffle 71 is located between the side drain outlet 13 and the self-circulating water outlet valve 51. This design creates a height difference between the side drain outlet 13 and the baffle 71, and another height difference between the baffle 71 and the self-circulating water outlet valve 51.

[0043] Multiple spaced drainage spiral plates 72 are rotatably installed on the baffle 71, which can guide the water on the baffle 71 into the bottom of the tank 1.

[0044] In this embodiment, the drainage spiral plate 72 is made of multiple long strips arranged in a ring on a rotating shaft. The rotating shaft is rotatably connected in the middle of the baffle 71. When the accumulated water is driven by gravity to rotate the long strips, the water enters the bottom of the tank 1. This design can block some impurities from entering the bottom, making it convenient for the filtration device 55 to perform filtration.

[0045] In use, open the water inlet valve 15 to fill the tank 1 with water up to the baffle 71 position, open the self-circulating water outlet valve 51, turn on the filter pump 52 and motor 2, and then input the gas mixture to be separated into the tank 1 through the air inlet 16. Through the spiral guide plate 6, impurities and liquid flow downwards and fall onto the baffle 71, completing the initial separation. Under the action of the filter pump 52, the spray pipe 54 continues to spray water onto the gas mixture to further separate the impurities. The gas then rises through the rotating spikes 33 and the demister 4 for three-stage separation. The clean gas is discharged through the air outlet 11.

[0046] During this process, when the water falling onto the baffle 71 reaches a certain weight, it drives the drainage spiral plate 72 to rotate, and then the water re-enters the bottom of the tank 1. When there is too much water and impurity mixture remaining on the baffle 71, it is discharged through the side drain port 13 to further filter impurities and save water resources. Then, it is recycled under the action of the filtrate pump 52, which is energy-saving and environmentally friendly. After use, the control valve on the bottom drain port 14 is opened to discharge the water and impurity mixture.

[0047] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
