Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, specifically to a steam-water separator. Background Technology

[0002] The papermaking process generates a large amount of water vapor, which diffuses into the workshop, accumulating and reducing visibility. This results in high temperatures and a sauna-like environment for workers, impacting their efficiency and posing safety hazards. To avoid disrupting normal operations, a fan uses negative pressure to draw the mist from the suction port and send it to a vapor-water separator. This separator removes the moisture from the mist, releasing clean air and preventing environmental pollution. However, existing vapor-water separators suffer from incomplete moisture separation and low efficiency. To increase efficiency, current separators have long internal airflow channels and large volumes. Therefore, to overcome these shortcomings, improvements to the existing technology are necessary. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a high-efficiency steam-water separator with high steam-water separation efficiency and clean water separation.

[0004] This utility model is achieved through the following technical solution: a steam-water separator, including a housing, an air inlet on the side of the housing, an exhaust port on the top of the housing, and a baffle separation mechanism, a centrifugal separation mechanism and an impact separation mechanism respectively arranged from top to bottom inside the housing. The air inlet end of the baffle separation mechanism is connected to the housing, the exhaust end of the baffle separation mechanism is connected to the exhaust port, the air inlet end of the centrifugal separation mechanism is connected to the air inlet, and the exhaust end of the centrifugal separation mechanism is located above the impact separation mechanism and is opposite to the impact separation mechanism.

[0005] Furthermore, the impact separation mechanism includes a support column and an adhesive plate covering the support column, and the adhesive plate has a drainage hole.

[0006] Furthermore, the diameter of the drain hole is less than 30 mm.

[0007] Furthermore, the centrifugal separation mechanism includes an air intake channel, and the air intake channel is provided with a plurality of guide plates along the airflow direction, the plurality of guide plates dividing the inner cavity of the air intake channel into a plurality of guide channels.

[0008] Furthermore, the air intake channel is an arc-shaped channel, and the inner diameter of the guide channel on the side with a larger radius of curvature gradually decreases to the inner diameter of the guide channel on the side with a smaller radius of curvature.

[0009] Furthermore, the air intake channel is a curved channel.

[0010] Furthermore, the flow separation mechanism includes a flow separation layer and a baffle layer arranged from bottom to top. The air inlet of the flow separation mechanism is connected to the housing, and the air outlet of the flow separation mechanism is connected to the exhaust port.

[0011] Furthermore, the baffle layer is provided with several layers of baffles, and each layer of the baffles is provided with several exhaust holes, and the baffle layer includes several layers of baffle mesh plates.

[0012] Furthermore, the exhaust holes of the two adjacent layers of baffles are staggered.

[0013] Furthermore, a drain port is provided at the lower end of the housing, and a drain pipe is provided at the drain end of the drain port, with an automatic drain device connected to the drain pipe.

[0014] Compared to existing technologies, this invention utilizes a centrifugal separation mechanism. When the mist passes through the arc-shaped channel, centrifugal force is generated, causing water to adhere primarily to the large arc-shaped wall of the curved channel and accumulate into water droplets. The multiple curved channels increase the contact time and area between the mist and the curved air intake channel, increasing centrifugal force and making the water separation effect more pronounced. The mist continues to enter the housing and impacts the separation mechanism, causing water vapor to adhere and accumulate into droplets before falling. The mist then continues to flow upwards into the deflector separation mechanism, where water vapor adheres and accumulates into droplets before falling. Finally, the three water vapor separation mechanisms separate the water from the mist, and the resulting clean air is discharged from the exhaust port. This invention allows for a longer contact time and a larger adhesion area for the airflow within the housing, thereby improving the steam-water separation efficiency. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 and Figure 2 The present invention discloses a steam-water separator, comprising a housing 1, an air inlet 2 on the side of the housing 1, and an exhaust outlet 3 on the top of the housing 1. Inside the housing 1, from top to bottom, there are a baffle separation mechanism 4, a centrifugal separation mechanism 5, and an impact separation mechanism 6. The air inlet end of the baffle separation mechanism 4 is connected to the housing 1, and the exhaust end of the baffle separation mechanism 4 is connected to the exhaust outlet 3. The air inlet end of the centrifugal separation mechanism 5 is connected to the air inlet 2, and the exhaust end of the centrifugal separation mechanism 5 is located above the impact separation mechanism 6 and is opposite to the impact separation mechanism 6.

[0021] The impact separation mechanism 6 includes a support column 9 and an adhesion plate 7 covering the support column 9. The adhesion plate 7 has a drain hole 8. Water vapor is sprayed directly onto the adhesion plate 7, and the water adheres to its surface. The drain hole 8 has a diameter of less than 30 mm. The mist enters through the air inlet channel 10 and flows downwards, contacting the adhesion plate 7. Some of the mist rises and contacts the baffle plate 15 and the baffle 13, increasing the contact area and condensation time, thus improving the vapor-water separation efficiency. Finally, it is discharged from the exhaust port 3. The liquid is adhered and separated on the adhesion plate 7, flowing downwards from the drain hole 8 to the bottom of the housing 1. It adheres to the bottom of the baffle plate 15 and the baffle 13, accumulating into water droplets that drip downwards to the bottom of the housing 1, and finally being discharged from the drain port 16.

[0022] The centrifugal separation mechanism 5 includes an air inlet channel 10. Inside the air inlet channel 10, several guide plates 11 are arranged along the airflow direction, dividing the inner cavity of the air inlet channel 10 into several guide channels 12. When the mist passes through the arc-shaped channels 12, centrifugal force is generated, causing water to adhere to the large arc-shaped walls and accumulate into water droplets. The arc-shaped channels increase the contact time and contact area between the mist and the air inlet channel, enhancing the centrifugal force water separation effect. The separated liquid flows into the bottom of the housing 1 and is discharged from the drain port 16. The guide channels 12 facilitate the uniform entry of mist into the housing 1, resulting in more uniform contact with the adhesion plates 7 and improving the vapor-water separation effect.

[0023] The intake end of the intake channel 10 is connected to the intake port 2, and the exhaust end of the intake channel 10 is located above and opposite to the impact separation mechanism 6. The gas discharged from the intake channel 10 is directly sprayed onto the adhesion plate 7, and the moisture in the mist adheres to the adhesion plate 7, thus achieving vapor-water separation.

[0024] The air intake channel 10 is an arc-shaped pipe. The inner diameter of the guide channel 12 on the side with a larger radius of curvature gradually decreases from the side with a smaller radius of curvature to the side with a smaller radius of curvature. The smaller the inner diameter of the guide channel 12, the greater the wind speed. The larger the radius of the guide channel 12 along the radial direction away from the center of the rotating shaft, the greater the centrifugal force. Conversely, the larger the inner diameter of the guide channel 12, the lower the wind speed. The smaller the radius of the guide channel 12 along the radial direction away from the center of the rotating shaft, the smaller the centrifugal force. Because the radius of the guide channel 12 within the air intake channel 10 gradually decreases from the outside to the inside, the wind speed gradually decreases. To make the mist more uniform, the inner diameter of the guide channel 12 gradually decreases from the outside to the inside, improving the uniformity of wind speed. In one specific embodiment, the air intake channel 10 is a curved pipe. After the mist enters the air intake channel 10, it is thrown against the inner wall of the guide channel 12 with a larger arc length due to centrifugal force. Water droplets drip down along the inner wall of the guide channel 12, thus achieving vapor-water separation. Accordingly, the guide channel 12 is a curved guide channel, and the guide plate 11 is a curved guide plate.

[0025] Through the centrifugal separation mechanism 5, under the action of centrifugal force, most of the water vapor adheres tightly to the outer circumferential surface of the inner cavity of the multi-layer guide channel 12, while water vapor with a higher quality than air adheres to the circumferential surface under the action of centrifugal force, thus achieving the effect of water vapor separation.

[0026] The flow separation mechanism 4 includes a baffle layer and a flow deflector layer arranged from bottom to top. The air inlet of the flow separation mechanism 4 is connected to the housing 1, and the exhaust end of the flow separation mechanism 4 is connected to the exhaust port 3. The outer diameter of the adhesion plate 7 is larger than the outer diameter of the exhaust end of the air inlet channel 10 to ensure that the mist is in full contact with the adhesion plate 7 and improve the water vapor separation effect.

[0027] The baffle layer has several layers of baffles 13, each with several exhaust holes 14. The baffle layer includes several layers of baffle mesh plates 15. The exhaust holes 14 of adjacent baffle layers 13 are staggered, causing the mist to move upwards through the baffles, increasing the contact area and contact time between the mist and the baffles, thus improving the separation flow rate and separation efficiency. Of course, if the water content in the mist is low, the baffle separation mechanism 4 can have only one layer of baffles 13; if the water content in the mist is high, the baffle separation mechanism 4 can have two or more layers of baffles 13. The baffle layer includes two layers of baffle mesh plates 15. After the mist is drawn into the adhesion plate 7 inside the housing 1, the airflow enters the baffle mesh plate 15 upwards. Some of the mist contacts and adheres to the bottom of the baffle 13, accumulating to form water droplets. After further vapor-water separation, the mist is discharged through the exhaust holes 14, and the clean air after demisting is discharged. The mist undergoes multiple demisting processes along the baffle mesh plate and the baffle orifice plate, with water continuously adhering to the surface of the baffle plates, resulting in good separation effect.

[0028] The lower end of the housing 1 is provided with a drain port 16, from which the separated liquid is discharged. The drain end of the drain port 16 is provided with a drain pipe, and an automatic drain device is connected to the drain pipe to prevent mist from being discharged from the drain port 16.

[0029] The bottom of the housing 1 is provided with support feet 17. The side of the housing 1 is also provided with a maintenance opening 18.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
