Description

Technical Field

[0001] This utility model relates to the technical field of epoxy purification equipment, and more specifically, to a cleaning tower for epoxy purification. Background Technology

[0002] Existing cleaning towers have several shortcomings in the epoxy purification process. Traditional cleaning towers have relatively simple internal structures, and the cleaning effect of the spray device is poor, resulting in incomplete removal of impurities from the epoxy and affecting the purification quality. At the same time, the gas-liquid separation effect is also unsatisfactory, and liquid entrainment is prone to occur, reducing the purity of the epoxy. Moreover, existing cleaning towers are mostly fixed packing layers, which are extremely inconvenient to operate when the packing needs to be replaced or cleaned, consuming a lot of time and manpower. Utility Model Content

[0003] This application provides a cleaning tower for epoxy purification, which solves the problems of traditional cleaning towers having a simple internal structure and poor cleaning effect of the spray device, resulting in incomplete removal of impurities in the epoxy and affecting the purification quality; at the same time, the gas-liquid separation effect is also not ideal, and liquid entrainment is prone to occur, reducing the purity of the epoxy; and existing cleaning towers are mostly fixed packing layers, which are extremely inconvenient to operate and consume a lot of time and manpower when the packing needs to be replaced or cleaned.

[0004] This application provides a cleaning tower for epoxy purification, including a tower body, an air inlet pipe at the top of the tower body, a liquid outlet pipe at the bottom of the tower body, a spraying device inside the tower body, the spraying device including an annular spray pipe and a nozzle, the nozzle spraying outlet facing the center of the tower body, a water inlet pipe installed on the annular spray pipe, a baffle plate below the spraying device, a packing layer below the baffle plate, the packing layer being installed inside the tower body via a lifting mechanism, the lifting mechanism being fixedly installed on a fixed platform, folding curtains being installed above and below the connection between the packing layer and the lifting mechanism on the tower body, and a cyclone separator below the packing layer, the cyclone separator being positioned above the air outlet pipe at the bottom of the tower body.

[0005] Preferably, the nozzles are evenly distributed on the annular spray pipe.

[0006] Preferably, the baffle plate is made of corrosion-resistant polypropylene.

[0007] Preferably, the surface of the guide vanes of the cyclone separator is provided with a hydrophobic coating.

[0008] Preferably, the lifting mechanism includes a motor, a lead screw, a limit rod, a lifting bracket, and a fixing rod. The motor is connected to the lead screw via a reducer, the lifting bracket is mounted on the lead screw and the limit rod, and the lifting bracket is connected to the packing layer via the fixing rod.

[0009] Preferably, the tower body is provided with inspection ports on the top and sides.

[0010] Preferably, the folding curtain is made of a corrosion-resistant and rust-resistant material.

[0011] As can be seen from the above technical solution, this application provides a cleaning tower for epoxy purification. In use, epoxy gas enters from the inlet pipe at the top of the tower and comes into contact with the liquid sprayed by the spray device. The liquid and epoxy gas fully collide and mix, initially washing away impurities. After spraying, the gas-liquid mixture continues to flow downward to the baffle plate. The wavy baffle plate causes the mixture to bend repeatedly. Some liquid collides with the baffle plate due to inertia and separates. The mixture passes through a liftable packing layer. The porous ceramic Pall ring packing provides a huge contact surface area for the gas and liquid, allowing the impurities in the epoxy gas to be fully absorbed by the liquid. The height and filling amount of the packing layer can be adjusted according to actual needs through the lifting mechanism to achieve the best purification effect. The mixture after passing through the packing layer enters the cyclone separator. The inclined guide vanes cause the mixture to rotate and generate centrifugal force. The remaining liquid is thrown against the tower wall and flows to the liquid outlet pipe for discharge. The purified epoxy gas is discharged from the gas outlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The spray device design of this utility model has multiple nozzles evenly distributed on the annular spray pipe at a 60-degree angle, which improves the gas-liquid contact area and cleaning effect, and can more effectively remove impurities in epoxy.

[0014] 2. This utility model features a baffle plate for initial separation, and a cyclone separator that uses centrifugal force for complete separation, effectively avoiding liquid entrainment and ensuring the high purity of the epoxy gas.

[0015] 3. The design of the adjustable packing layer in this utility model facilitates the replacement and cleaning of the packing, improves the flexibility and convenience of operation, and allows the packing layer to be adjusted as needed to adapt to different epoxy purification process requirements.

[0016] In summary, the multiple nozzles of the epoxy purification cleaning tower are evenly distributed at a 60-degree angle on the annular spray pipe, which increases the gas-liquid contact area and cleaning effect, and can more effectively remove impurities from the epoxy. The baffle plate is set for initial separation, and the cyclone separator uses centrifugal force to completely separate the components, effectively avoiding liquid entrainment and ensuring the high purity of the epoxy gas.

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] See Figure 1-7This application discloses a cleaning tower for epoxy purification. To address the problems of traditional cleaning towers having simple internal structures, poor cleaning effects from spray devices, resulting in incomplete removal of impurities from epoxy and affecting purification quality; simultaneously, the gas-liquid separation effect is also unsatisfactory, easily leading to liquid entrainment and reducing epoxy purity; furthermore, existing cleaning towers mostly use fixed packing layers, making replacement or cleaning extremely inconvenient and time-consuming. The proposed cleaning tower for epoxy purification features multiple nozzles evenly distributed at a 60-degree angle on an annular spray pipe, increasing the gas-liquid contact area and cleaning effect, more effectively removing impurities from epoxy. A baffle plate is used for initial separation, and a cyclone separator utilizes centrifugal force for complete separation, effectively avoiding liquid entrainment and ensuring high epoxy gas purity.

[0029] Specifically, a cleaning tower for epoxy purification includes a tower body 1. An inlet pipe 2 is provided at the top of the tower body 1, through which epoxy gas enters the tower. A liquid outlet pipe 14 is provided at the bottom of the tower body 1. A spraying device 3 is provided inside the tower body 1, comprising an annular spray pipe 301 and nozzles 302. The epoxy gas entering the tower comes into contact with the liquid sprayed from the spraying device 3, and the liquid and epoxy gas fully collide and mix, initially washing away impurities. The nozzles 302 are evenly distributed on the annular spray pipe 301, with the nozzles facing the center of the tower body 1. A water inlet pipe 9 is installed on the annular spray pipe 301. Multiple nozzles 302 are detachably and evenly distributed on the annular spray pipe 301 at a 60-degree angle, increasing the gas-liquid contact area and cleaning effect, and more effectively removing impurities from the epoxy. A baffle plate 5 is provided below the spraying device 3, and the baffle plate 5 is made of corrosion-resistant material. The corrosive polypropylene ensures good gas-liquid separation and adapts to the corrosive environment in the epoxy purification process, extending equipment life and reducing maintenance costs. After spraying, the gas-liquid mixture continues to flow downwards to the baffle plate 5. The wavy baffle plate 5 causes the mixture to be repeatedly deflected. Some liquid collides with the baffle plate 5 due to inertia and separates. A packing layer 6 is provided below the baffle plate 5. The packing layer 6 is detachable and has a liftable design, which facilitates the replacement and cleaning of the packing and improves the flexibility and convenience of operation. At the same time, the packing layer 6 can be adjusted as needed to adapt to different epoxy purification process requirements. The packing layer 6 is installed in the tower body 1 through the lifting mechanism 8. The separated mixture passes through the liftable packing layer 6. The porous ceramic Pall ring packing provides a huge contact surface area for gas and liquid, so that impurities in the epoxy gas are fully absorbed by the liquid.

[0030] The lifting mechanism 8 is fixedly installed on the fixed platform 15. The lifting mechanism 8 includes a motor 801, a lead screw 802, a limit rod 803, a lifting bracket 804, and a fixing rod 805. The motor 801 is connected to the lead screw 802 through a reducer. The lifting bracket 804 is installed on the lead screw 802 and the limit rod 803. The lifting bracket 804 is connected to the packing layer 6 through the fixing rod 805. The height and filling amount of the packing layer 6 can be adjusted according to actual needs through the lifting mechanism 8 to achieve the best purification effect. The connection between the packing layer 6 and the lifting mechanism 8 on the tower body 1 is... Folding curtains 7 are installed at the top and bottom of the joint. The folding curtains 7 are made of corrosion-resistant and rust-proof material. A hydrocyclone separator 10 is installed below the packing layer 6. The hydrocyclone separator 10 uses centrifugal force to completely separate the components, effectively avoiding liquid entrainment and ensuring the high purity of the epoxy gas. The hydrocyclone separator 10 is located above the gas outlet pipe 13 at the bottom of the tower body 1. The mixture passing through the packing layer 6 enters the hydrocyclone separator 10. The inclined guide vanes 11 cause the mixture to rotate, generating centrifugal force. The remaining liquid is thrown against the tower wall and flows to the liquid outlet pipe 14 for discharge. The purified epoxy gas is discharged from the gas outlet pipe 13. The surface of the guide vanes 11 of the hydrocyclone separator 10 is covered with a hydrophobic coating 12, which can accelerate the sliding speed of the liquid on the vane surface, prevent the liquid from accumulating on the vane surface, and improve the hydrocyclone separation effect and efficiency. At the same time, the hydrophobic coating 12 can also reduce the adhesion of liquid to the vanes and reduce the maintenance frequency of the equipment. The top and sides of the tower body 1 are equipped with inspection ports 4, which are used when the packing layer 6, nozzles 302, etc. need to be replaced or cleaned.

[0031] As can be seen from the above technical solution, when using an epoxy purification cleaning tower, epoxy gas enters from the inlet pipe 2 at the top of the tower body 1 and comes into contact with the liquid sprayed by the spray device 3. The liquid and epoxy gas fully collide and mix, initially washing away the impurities. After spraying, the gas-liquid mixture continues to flow downward to the baffle plate 5. The wavy baffle plate 5 causes the mixture to be repeatedly deflected. Some liquid collides with the baffle plate 5 due to inertia and separates. The separated mixture passes through the liftable packing layer 6. The porous ceramic Pall ring packing provides a huge contact surface area for the gas and liquid, allowing the impurities in the epoxy gas to be fully absorbed by the liquid. The height and filling amount of the packing layer 6 can be adjusted according to actual needs through the lifting mechanism 8 to achieve the best purification effect. The mixture passing through the packing layer 6 enters the cyclone separator 10. The inclined guide vanes 11 cause the mixture to rotate and generate centrifugal force. The remaining liquid is thrown against the tower wall and flows to the liquid outlet pipe 14 for discharge. The purified epoxy gas is discharged from the gas outlet pipe 13.
