Description

Technical Field

[0001] The present application relates to the technical field of organic waste gas treatment, and in particular to a centrifugal water bath device for removing high-boiling-point organic matter. Background Art

[0002] Industrial organic waste gases (VOCs) are a significant source of atmospheric pollutants. As the nation raises higher standards for air quality, VOC treatment technologies are constantly evolving. Currently, mature technologies include absorption, adsorption, condensation, combustion (including direct combustion, thermal storage, and catalytic combustion), and a combination of these methods. However, when VOCs contain high-boiling-point organic compounds, existing treatment technologies still have some technical limitations.

[0003] For example, when the condensation method is used to treat low-concentration organic waste gas containing high boiling points, the treatment efficiency is very low and the energy consumption is high; when the combustion method is used to treat low-concentration organic waste gas containing high boiling points, although the treatment efficiency can be guaranteed, the energy consumption is also high; when the adsorption method + combustion method combination process is used to treat low-concentration organic waste gas containing high boiling points, because the desorption temperature is generally between 180-220°C, it is difficult to desorb high-boiling-point organic matter, resulting in rapid failure of the adsorption medium, secondary pollution, and increased operating costs.

[0004] In view of this, we propose a centrifugal water bath device for removing high-boiling point organic matter. Summary of the Invention

[0037] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-6 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0038] The embodiment of the present application discloses a centrifugal water bath device for removing high-boiling-point organic matter.

[0039] Example 1:

[0040] Reference Figure 1 and Figure 2The centrifugal water bath device includes a housing 1, an air inlet pipe 2, and an air outlet pipe 3. The air inlet pipe 2 and the air outlet pipe 3 are respectively fixed to the upper portion of the housing 1, and the air outlet pipe 3 is connected to the interior of the housing 1. In this embodiment, the housing 1 is a stainless steel housing with a hollow interior and a square shape. The air inlet pipe 2 and the air outlet pipe 3 are located on opposite side walls of the housing 1. In other embodiments, the air inlet pipe 2 and the air outlet pipe 3 are located on the same side wall of the housing 1, or on adjacent side walls of the housing 1, that is, the directions of the air inlet pipe 2 and the air outlet pipe 3 can be adjusted according to the requirements of the on-site working conditions.

[0041] Reference Figure 2 An annular liquid storage tank 4 and a centrifugal chamber 5 are fixed in the casing 1, and an air inlet pipe 2 passes through the side wall of the casing 1. One end of the air inlet pipe 2 located in the casing 1 is fixedly connected to the top of the annular liquid storage tank 4 by bolts; that is, the air outlet of the air inlet pipe 2 is connected to the air inlet of the annular liquid storage tank 4. A water inlet pipe 6 is fixed to the side wall of the casing 1. One end of the water inlet pipe 6 passes through the side wall of the casing 1 and is connected to the inside of the annular liquid storage tank 4, and the other end is connected to a water source; that is, water can be injected into the annular liquid storage tank 4 through the water inlet pipe 6. In this embodiment, the end of the air inlet pipe 2 located in the casing 1 is in the shape of a truncated cone, and a flange is integrally formed at one end of the air inlet pipe 2 located in the casing 1. A flange is also integrally formed at the top of the annular liquid storage tank 4, and the air inlet pipe 2 and the annular liquid storage tank 4 are fixed together by the flange.

[0042] It should be noted that the annular liquid reservoir 4 is an annular, non-enclosed cavity, the inner ring of the annular liquid reservoir 4 is lower than the outer ring, and the connection between the water inlet pipe 6 and the annular liquid reservoir 4 is located on the outer ring of the annular liquid reservoir 4. In this embodiment, water is injected into the annular liquid reservoir 4 through the water inlet pipe 6. Since the inner ring of the annular liquid reservoir 4 is lower than the outer ring, water overflows from the inner ring of the annular liquid reservoir 4 to form a water curtain.

[0043] Reference Figure 2 In order to form a uniform water curtain on the inner ring of the annular liquid reservoir 4, an adjusting ring 9 is installed in the annular liquid reservoir 4. The height of the adjusting ring 9 is lower than the height of the outer ring of the annular liquid reservoir 4, and the height of the adjusting ring 9 is higher than the height of the inner ring of the annular liquid reservoir 4. In this embodiment, the adjusting ring 9 is integrally formed in the annular liquid reservoir 4, and the adjusting ring 9 and the inner ring of the annular liquid reservoir 4 are arranged concentrically. When water is injected into the annular liquid reservoir 4, the water in the annular liquid reservoir 4 will diffuse and flow outward, resulting in an uneven and complete water curtain formed in the annular liquid reservoir 4. The adjusting ring 9 buffers the impact force of the water flow flowing into the annular liquid reservoir 4 from the water inlet pipe 6, which helps to make the water curtain overflowing from the inner ring of the annular liquid reservoir 4 more uniform and complete, thereby allowing the gas containing organic matter to more fully contact the water curtain and improve the gas purification effect.

[0044] Reference Figure 2To remove organic matter and other impurities from the gas, the bottom of the annular liquid reservoir 4 is fixedly connected to the top of the centrifugal chamber 5 with bolts, so that the inner cavity of the annular liquid reservoir 4 is connected to the inner cavity of the centrifugal chamber 5. This facilitates the flow of gas from the air inlet pipe 2 into the annular liquid reservoir 4 and into the centrifugal chamber 5. A centrifugal impeller 7 is rotatably connected to the centrifugal chamber 5. A driving member 8 for driving the centrifugal impeller 7 is mounted on the casing 1. The driving member 8 adopts a waterproof motor.

[0045] Reference Figure 2 and Figure 3 To facilitate inspection and maintenance of the waterproof motor, an annular baffle 16 is welded to the interior of the housing 1, with the waterproof motor located within it. A maintenance window 17 is provided at the bottom of the housing 1, communicating with the interior of the annular baffle 16. In this embodiment, the annular baffle 16 blocks water from the housing 1, minimizing the risk of water contacting the waterproof motor and potentially damaging it. The maintenance window 17 allows the waterproof motor to be located outside the housing 1, making it easier to inspect and maintain the waterproof motor.

[0046] Reference Figure 2 and Figure 3 To reduce the rotational resistance of the centrifugal impeller 7, a mounting plate 18 on the centrifugal chamber 5 is bolted to the top of the annular baffle 16. Mounting plate 18 defines a through-hole 19 through which the output shaft of the waterproof motor passes. A sealing groove 20 is defined in the wall of through-hole 19, within which a bearing 21 is mounted. In this embodiment, mounting plate 18 facilitates securing the centrifugal chamber 5, and bearing 21 minimizes the rotational resistance of the centrifugal impeller 7 driven by the motor.

[0047] Reference Figure 2 and Figure 3 To improve the lubrication of bearing 21, an oil injection hole 22 is formed on mounting plate 18 and communicates with sealing groove 20. A sealing plug 23 is installed at the opening of oil injection hole 22. In this embodiment, sealing plug 23 is located within annular baffle 16 and is a rubber plug. Sealing oil is injected into sealing groove 20 through oil injection hole 22, facilitating a seal between mounting plate 18 and the motor's output shaft. This reduces the escape of gas from housing 1 through through-hole 19, thereby enhancing the purification of organic gases.

[0048] Reference Figure 2 and Figure 3In order to better remove high-boiling-point organic matter, a support plate 10 is fixed inside the box body 1, and a plurality of first filter holes 11 are opened on the support plate 10. In this embodiment, the outer wall of the support plate 10 is fixed to the inner wall of the box body 1 by welding, and the inner wall of the support plate 10 is fixed to the outer wall of the annular baffle plate 16 by welding, and the plurality of filter holes are evenly distributed on the support plate 10; after the organic gas contacts the water curtain or water bath, the small droplets will flow downward under the action of gravity, and pass through the first filter holes 11 of the support plate 10 and enter the bottom of the box body 1, which has the effect of separating part of the gas and water flow, so that the purified gas can flow upward to the top of the box body 1 and be discharged through the outlet pipe 3, thereby achieving the purpose of purifying the organic gas.

[0049] Reference Figure 2 and Figure 3 The bottom of the housing 1 is connected to a drain pipe 12 and an outlet pipe 13. The connection points of the drain pipe 12 and the outlet pipe 13 with the housing 1 are both located below the support plate 10. The outlet pipe 13 is located at a higher height on the housing 1 than the drain pipe 12. In this embodiment, water is discharged from the bottom of the housing 1 through the outlet pipe 13, facilitating the recirculation of purified water into the water inlet pipe 6. Sludge is discharged from the bottom of the housing 1 through the drain pipe 12, facilitating the cleaning of the sludge inside the housing 1.

[0050] Reference Figure 2 and Figure 3 The upper surface of the support plate 10 is mounted with a plurality of spiral plates 14, which are evenly distributed and fixed on the support plate 10, and are located outside the centrifugal chamber 5. The spiral plates 14 are provided with a plurality of second filter holes 15. In this embodiment, there are four spiral plates 14, each having a spiral cross-section. The bottom ends of the spiral plates 14 are fixed to the upper surface of the support plate 10 by welding. The mounting plate 18 of the centrifugal chamber 5 is provided with four channels for the water bath to flow through. The water bath falling through the four channels will respectively enter the chambers surrounded by the four spiral plates 14 and the annular baffle plate 16. After the organic gas contacts the water curtain or water bath, under the action of centrifugal force, some of the small droplets pass through the second filter holes 15 and are ejected toward the inner wall of the box body 1, thereby achieving the effect of partially separating the gas and water flow, facilitating the purified gas to be spiraled from bottom to top in the spiral plates 14 into the top of the box body 1, thereby achieving a better purification effect of the organic gas.

[0051] Reference Figure 2 and Figure 4The end surface of the annular liquid reservoir 4 facing the centrifugal chamber 5 is provided with a recessed groove 24, in which a sealing ring 25 is embedded and fixed. In this embodiment, installing the sealing ring 25 in the recessed groove 24 can reduce the sealing ring 25 from falling out from between the annular liquid reservoir 4 and the centrifugal chamber 5; at the same time, the sealing ring 25 can reduce the leakage of gas from the annular liquid reservoir 4 and the centrifugal chamber 5, thereby improving the purification effect of organic gas.

[0052] The working principle of a centrifugal water bath device for removing high-boiling-point organic matter in an embodiment of the present application is as follows: before the centrifugal water bath device is turned on, water is first introduced through the water inlet pipe 6. After the water enters the annular liquid reservoir 4, the water overflows from the inner ring of the annular liquid reservoir 4 to form a water curtain. Then, the motor is turned on, and the centrifugal impeller 7 is driven by the motor to rotate at high speed, creating a negative pressure state inside the centrifugal chamber 5. At this time, the water overflowing from the annular liquid reservoir 4 is cut into small droplets of millimeter to nanometer size by the action of the centrifugal impeller 7. The droplets are ejected toward the inner wall of the centrifugal chamber 5, where they collide with the inner wall of the centrifugal chamber 5, forming a water bath of small droplets of millimeter to nanometer size inside the centrifugal chamber 5.

[0053] The gas containing high-boiling-point organic matter enters through the air inlet pipe 2. When passing through the water curtain, a heat transfer process occurs between the gas and the liquid, and the gas is cooled to 5-10°C. At this time, the high-boiling-point organic matter exists in the form of small droplets or aerosols. After entering the centrifugal chamber 5, the high-boiling-point organic matter in the form of small droplets or aerosols fully contacts the small droplets. Under the action of centrifugal force, the mixed small droplets are ejected toward the inner wall of the centrifugal chamber 5 again and flow downward along the inner wall of the centrifugal chamber 5. The gas carries the small droplets out from the lower part of the centrifugal chamber 5 and enters the chamber surrounded by the spiral plate 14 and the annular baffle plate 16.

[0054] Under the influence of centrifugal force, some small droplets pass through the second filter holes 15 of the spiral plate 14 and are ejected toward the inner wall of the housing 1. There, they flow downward under the influence of gravity, passing through the first filter holes 11 of the support plate 10 and entering the bottom of the housing 1. Another portion of small droplets, driven by wind, pass directly through the first filter holes 11 of the support plate 10 and enter the bottom of the housing 1. The water containing high-boiling-point organic matter is discharged through the water outlet pipe 13 and, after purification, is re-circulated into the water inlet pipe 6. The purified gas spirals upward within the spiral plate 14 into the top of the housing 1 and is discharged through the gas outlet pipe 3.

[0055] It should be noted that the high-speed rotation of the centrifugal impeller 7 generates negative pressure, which provides power to the gas, eliminating the need for a separate fan. The device combines the performance of a water bath, high gravity, and centrifugal forces, resulting in a compact structure, minimal footprint, and high dust removal efficiency. It not only efficiently removes high-boiling-point organic matter, but also effectively treats dust and particulate matter. It is also highly effective in treating water-soluble organic and inorganic matter in the exhaust gas.

[0056] Example 2: Reference Figure 5 and Figure 6 This embodiment differs from the first embodiment in that a humidifying curtain 26 is installed on the inner sidewall of the housing 1, located within the outlet pipe 3. The humidifying curtain 26 comprises a frame 261 and a plurality of curtain pieces 262, each spaced apart and mounted within the frame 261. The frame 261 defines a water reservoir 27, with both ends of the curtain pieces 262 extending into the reservoir. A water pipe 28 is installed on the sidewall of the housing 1, one end of which is connected to the reservoir 27 and the other end to a water source. A cover 29, sealing the reservoir 27, is bolted to the frame 261. In this embodiment, water is injected into the reservoir 27 through the water pipe 28. The curtain pieces 262 absorb the water and remain moist, allowing them to continuously adsorb and filter the gas, thereby extending the service life of the humidifying curtain 26.

[0057] Reference Figure 5 and Figure 6 Between two adjacent curtain slats 262, a plurality of pleated curtains 30 are installed, spaced apart along the height of the curtain slats 262. Ventilation holes 31 are provided on each pleated curtain 30 in the same direction, and the vents 31 are staggered. In this embodiment, the pleated curtains 30 are fixed to the curtain slats 262 using bolts. This increases the contact area between the pleated curtains 30 and the air. The staggered distribution of the vents 31 increases the air flow path, ensuring sufficient contact between the pleated curtains 30 and the curtain slats 262, thereby enhancing the air filtering effect. The pleated curtains 30 connect the curtain slats 262 into a single unit and can be adjusted to fold and unfold between the curtain slats 262, meeting the requirements of installation in different spaces.

Unless otherwise specified, any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features. In other words, unless otherwise specified, each feature is merely an example of a series of equivalent or similar features.
