Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastics production, especially to a water gas separation device. BACKGROUND

[0002] In the process of strip granulation production, the strip needs to be cooled, and the most common cooling process in the cooling process of polymer material processing is to cool the strip with cooling water in a water tank. After the strip is cooled in the water tank, water will be adhered to the surface of the strip. Cutting is an essential process in polymer material processing, and too much water on the strip will not only affect the service life of the cutting equipment, but also easily cause the water content of the finished product to exceed the standard. Therefore, the water removal process of the strip in the polymer material processing process is particularly important.

[0003] At present, the water removal process of the strip is usually carried out by a negative pressure water removal device, that is, the gas-liquid mixture on the strip is sucked into the negative pressure water removal device by negative pressure, and then separated into water beads and gas under the action of a water gas separator, thereby completing the water removal operation of the strip. However, part of the separated gas still contains water, which cannot be recycled (for example, used to dry the strip), which undoubtedly leads to waste of energy. UTILITY MODEL CONTENTS

[0030] Please refer to Figures 1 to 3 The present application provides a water-gas separation device, which comprises a water-gas separation assembly 10 and a fan 40.

[0031] Specifically, the water-gas separation assembly 10 comprises a shell 11, a gas guide pipe 12 and a blade 14. The gas guide pipe 12 is arranged inside the shell 11 and along the height direction X of the shell 11. The outer periphery of the gas guide pipe 12 is provided with a partition sheet 15. The outer edge of the partition sheet 15 is connected with the inner wall of the shell 11 to divide the inside of the shell 11 into a first space 10a and a second space 10b. The upper end of the gas guide pipe 12 is communicated with the first space 10a, and the lower end is communicated with the second space 10b. The blade 14 is arranged around the pipe of the gas guide pipe 12 in the second space 10b. The shell 11 is connected with an air inlet pipe 20 and an air outlet pipe 30. The air inlet pipe 20 and the air outlet pipe 30 are arranged on opposite sides of the shell 11. The air inlet pipe 20 is communicated with the second space 10b, and the air outlet pipe 30 is communicated with the first space 10a. The air inlet end of the fan 40 is communicated with the air outlet pipe 30.

[0032] Based on the above technical features, the water-gas separation device is provided with the partition sheet 15 around the outer periphery of the gas guide pipe 12 to divide the inside of the shell 11 into the first space 10a and the second space 10b. The blade 14 is arranged around the pipe of the gas guide pipe 12 in the second space 10b. The gas-liquid mixture entering the second space 10b through the air inlet pipe 20 sequentially contacts the blade 14 during downward flow, and then condenses into water droplets on the surface of the blade 14 and falls to the bottom of the shell 11. The separated gas enters the first space 10a through the gas guide pipe 12 and flows out of the shell 11 through the air outlet pipe 30 under the action of the fan 40 and blows onto the surface of the material strip. The negative pressure water removal structure is simple in structure, high in water-gas separation efficiency and good in effect, ensures that the water content in the separated gas is very low, thereby ensuring that the separated gas can be recycled, which is beneficial to saving production cost.

[0033] Preferably, the blade 14 is made of metal material (such as stainless steel), and an ultra-hydrophobic coating (such as polytetrafluoroethylene coating) is coated on the surface of the blade 14 to ensure that the water droplets condensed on the blade 14 can flow and fall into the bottom of the shell 11. Similarly, the partition sheet 15 is made of metal material, and an ultra-hydrophobic coating is coated on the surface of the partition sheet 15 to accelerate the flow of the water droplets formed by condensation.

[0034] Based on the above knowledge, the partition sheet 15 is made of metal material, and the outer edge of the partition sheet 15 and the inside of the shell 11 can be welded to firmly connect the partition sheet 15 with the shell 11, avoiding falling off due to unstable connection during use and affecting normal water-gas separation.

[0035] Exemplarily, the negative pressure water removal structure of the application can change the length-diameter ratio of the air guide pipe and the structure of the blade according to the air inlet amount and the liquid content, thereby improving the gas-liquid separation effect and ensuring that the inner wall of the shell of the fan remains dry, which is conducive to prolonging the service life of the fan.

[0036] Exemplarily, the partition sheet and the height direction of the shell form an included angle, and the included angle is between 32°-35°, so that the partition sheet and the port of the air outlet pipe form a dead angle, which ensures that the liquid cannot be carried out by the airflow and is only blocked by the partition sheet to form water droplets; if the angle is small, the blade will be lower than the port of the air outlet pipe and cannot form a dead angle, which will cause the liquid to be carried away by the airflow; if the angle is large, the volume of the device will be large, increasing the cost.

[0037] Exemplarily, the blade around the pipe body of the air guide pipe can adopt a double helix arrangement, that is, a blade with a large contact area is helically arranged on the air guide pipe, and then another blade with a small contact area is arranged on the inner side, thereby forming a double helix design to improve the gas-liquid separation effect. In addition, the included angle between the blade and the air guide pipe is between 63°-65° to ensure better separation effect; if the included angle between the blade and the air guide pipe is too small, the gas-liquid separation effect will be affected; if the included angle between the blade and the reversing pipe is too large, the pressure loss during separation will increase, increasing energy consumption.

[0038] Exemplarily, the fan 40 is a negative pressure centrifugal fan for providing power for the entire set of equipment, for example: under the action of the negative pressure centrifugal fan, a 1500pa-2500Pa negative pressure area is formed at the inlet of the air inlet pipe 20 to use the pressure difference to suck the gas-liquid mixture on the strip into the shell 11 for separation. In addition, different types of negative pressure centrifugal fans can be selected according to different suction water vapor suction requirements.

[0039] It should be noted that when the air guide pipe 12 is installed inside the shell 11, the outer edge of the partition sheet 15 arranged on the periphery of the air guide pipe 12 needs to be tightly connected with the inner wall of the shell 11 to divide the inside of the shell 11 into the first space 10a and the second space 10b, so that the gas-liquid mixture entering the second space 10b through the air inlet pipe 20 can only flow from the air guide pipe 12 into the first space 10a, and cannot flow into the first space 10a from the gap between the partition sheet 15 and the inner wall of the shell 11. In this way, the gas-liquid mixture entering the second space 10b can sequentially contact the blade 14 during downward flow, so that water droplets are formed on the surface of the blade 14, and the separated gas flows downward to the lower end of the air guide pipe 12 and enters the inside of the air guide pipe 12, and finally flows into the first space 10a, thereby realizing water vapor separation of the gas-liquid mixture with high water vapor separation efficiency and good effect.

[0040] Please refer toFigure 3 In a possible implementation, the water-gas separation assembly further comprises a flow guide pipe 13 arranged in the second space 10b and along the height direction X of the shell 11, and the partition sheet 15 is provided with a notch 15a communicating with the flow guide pipe 13.

[0041] Exemplarily, the gas entering the first space 10a through the gas guide pipe 12 still contains a small amount of water. Since the upper end of the gas guide pipe 12 is located below the top of the shell 11, the gas entering the first space 10a blows towards the top of the shell 11, and then condenses into water droplets at the top of the shell 11 and drips onto the surface of the partition sheet 15. Therefore, in the present embodiment, the notch 15a is provided on the partition sheet 15, and the flow guide pipe 13 is arranged in the second space 10b and communicates with the notch 15a. Thus, the water droplets dripping on the partition sheet 15 can flow into the flow guide pipe 13 from the notch 15a, and then flow into the bottom of the shell 11 through the flow guide pipe 13. In this way, the separated water can be collected at the bottom of the shell 11 for subsequent reuse.

[0042] Further, the separated gas entering the first space 10a contacts the top of the shell 11, and then condenses into water droplets at the top of the shell 11 and drips onto the surface of the partition sheet 15 under the action of gravity. To accelerate the flow of water droplets on the partition sheet 15 into the flow guide pipe 13, the partition sheet 15 can be connected to the pipe of the gas guide pipe 12 in a coiled manner. Specifically, the partition sheet 15 has opposite first and second ends, and the partition sheet 15 is coiled on the pipe of the gas guide pipe 12 along the direction from the first end to the second end, with the second end close to the flow guide pipe 13 and the notch provided on the second end. In this way, the water droplets dripping on the surface of the partition sheet 15 can flow towards the notch 15a and then flow into the flow guide pipe 13, avoiding the water droplets staying on the surface of the partition sheet 15 for a long time and causing the gas to re-mix with water.

[0043] In a possible implementation, the water-gas separation assembly further comprises a flow guide plate 16, the bottom of the shell 11 is provided with a liquid outlet 100, the flow guide plate 16 is arranged in the second space 10b and close to the liquid outlet 100, a chamber 200 is formed between the flow guide plate 16 and the liquid outlet 100, and the outer side wall of the flow guide plate 16 and the inner side wall of the shell 11 have a gap for the liquid to flow into the chamber.

[0044] Exemplarily, the gas still contacts the liquid dropping to the bottom of the shell 11 in the process of flowing downward, and then the gas-liquid mixture is reformed to enter the first space 10a through the gas guide pipe 12, so that the moisture is reattached to the surface of the material strip after the collected gas blows to the surface of the material strip, resulting in that the moisture of the finished product exceeds the standard. In this embodiment, the liquid dropping to the bottom of the shell 11 is discharged through the liquid discharge port 100 arranged at the bottom of the shell 11, and the flow guide plate 16 is arranged between the gas guide pipe 12 and the liquid discharge port 100, and the gap is arranged between the outer side wall of the flow guide plate 16 and the inner side wall of the shell 11, so that the gas only contacts the surface of the flow guide plate 16 facing the gas guide pipe 12 when flowing downward, and does not directly contact the liquid in the cavity 200, thereby effectively avoiding the gas after separation from contacting the liquid to re-form the gas-liquid mixture. In addition, the water mixed in the gas is condensed to form water droplets on the surface of the flow guide plate 16 after contacting the surface of the flow guide plate 16, and then the water droplets flow into the cavity 200 from the outer side wall of the flow guide plate 16, thereby further improving the water-gas separation effect.

[0045] In a possible implementation, the gap is between 3mm and 5mm. The gap is arranged in the above range in order to avoid that the gap is too large and the water vapor escapes from the cavity 200 to mix with the gas to re-form the gas-liquid mixture.

[0046] Please refer to Figure 3 In a possible implementation, the outer side wall of the flow guide plate 16 has an inclined surface 16a inclined downward to the inner side wall of the shell 11, and the lower end of the flow guide pipe 13 is opposite to the inclined surface 16a. In this way, it is beneficial to accelerate the water droplets dropping on the flow guide plate 16 to flow into the cavity 200, and avoid that the water droplets on the flow guide plate 16 contact the gas for a long time to re-form the gas-liquid mixture.

[0047] Please refer to Figure 2 In a possible implementation, the liquid collection assembly 90 is further included, the liquid collection assembly 90 includes the liquid collecting box 91 and the liquid collecting pipe 92, one end of the liquid collecting pipe 92 is connected with the liquid discharge port 100, and the other end of the liquid collecting pipe 92 is connected with the liquid collecting box 91. In this way, the liquid discharged from the liquid discharge port 100 is collected into the liquid collecting box 91 through the liquid collecting pipe 92, so as to realize the recycling of the liquid and save the production cost.

[0048] Since the liquid collecting box 91 is communicated with the liquid discharge port 100 through the liquid collecting pipe 92, in order to make the liquid at the bottom of the shell 11 flow into the liquid collecting box 91 smoothly, the pressure in the liquid collecting box 91 and the chamber 200 needs to be balanced. For this purpose, in one possible embodiment, the liquid collecting assembly 90 further comprises a connecting pipe 94 and a pneumatic ball valve 93, one end of the connecting pipe 94 is communicated with the second space 10b, the other end of the connecting pipe 94 is connected with the liquid collecting box 91, and the pneumatic ball valve 93 is arranged on the connecting pipe 94. In this way, when the gas-liquid mixture is introduced into the shell 11, the pneumatic ball valve 93 is first controlled to be opened, so that the pressure in the liquid collecting box 91 and the chamber 200 is balanced, and then the starting ball valve is controlled to be closed.

[0049] In one possible embodiment, the air guide member 50 is further connected with the air outlet end of the fan 40, and the air guide member 50 is provided with an air guide opening 50a for guiding the separated gas to the material strip. In this way, the separated gas flows out of the shell 11 from the air outlet pipe 30 under the action of the fan and enters the air guide member 50, and then blows on the surface of the material strip from the air guide opening 50a of the air guide member 50, so that the separated gas can be recycled.

[0050] In one possible embodiment, the water suction head 60 is further connected with the end of the air inlet pipe 20 away from the shell 11 through a hose. By connecting the water suction head 60 with the end of the air inlet pipe 20 away from the shell 11, a negative pressure area can be formed near the water suction head 60 under the action of the fan 40, and when the material strip passes through the water suction head 60, the moisture on the surface of the material strip is sucked into the shell 11 for water-gas separation. In this way, a larger negative pressure area can be formed by means of the water suction head 60, so that the moisture on the surface of the material strip can be more efficiently sucked into the shell 11.

[0051] In one possible embodiment, the machine case 70 and the moving wheels 80 connected with the bottom surface of the machine case 70 are further included, the fan 40 is installed in the machine case 70, the air guide member 50 is installed on the outer surface of the machine case 70, the lower part of the shell 11 extends into the machine case 70, the upper part of the shell 11 extends out of the top of the machine case 70, and the air inlet pipe and the air outlet pipe are located outside the machine case 70. In this way, the machine case 70 can be moved at will by means of the moving wheels 80 connected with the bottom surface of the machine case 70, so as to meet the water removal of the material strip at different positions.

[0052] The working process of the utility model is as follows:

[0053] In the production process of the strip granulation, the molten material strip of the extruder head is cooled by the water tank, and then enters the cutting machine for cutting after passing through the water-gas separation device. When the material strip is cooled by the water tank, water will adhere to the surface of the material strip due to the influence of the surface tension of water. When the material strip passes through the water suction head 60, a negative pressure zone is formed near the water suction head 60 under the action of the fan 40, so that the water on the surface of the material strip and the air in the negative pressure zone are sucked into the second space 10b from the air inlet pipe 20 to form a gas-liquid mixture. Then, the gas-liquid mixture successively spirally contacts the blades 14 arranged on the air guide pipe during downward flow to change the flow speed of the gas-liquid mixture, and then condenses into water droplets on the surface of the blades 14 and falls to the bottom of the shell 11. The liquid flowing out of the liquid outlet 100 is collected into the liquid collecting box 91 by the liquid collecting pipe 92, so as to facilitate the subsequent reuse of the liquid. The separated gas enters the first space 10a through the air guide pipe 12, and is blown from the air guide piece 50 to the surface of the material strip cooled by the water tank under the action of the fan 40, realizing the recycling of the gas.

[0054] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and some modifications and improvements can be made, which belong to the protection scope of the present application.
