Description

Technical Field

[0001] The invention belongs to the technical field of distillation preparation, in particular to a distillation device for preparing trixylene phosphate. Background Art

[0002] Trixylene phosphate is a chemical substance widely used in rubber and plastic conveyor belts and other fields. In its production process, distillation is a key separation step used to purify and refine the reaction products. The design of the preparation distillation unit needs to take into account factors such as the characteristics of the raw materials, reaction conditions, product purity requirements, and energy efficiency.

[0003] In the current prior art, when preparing distillation of trixylene phosphate, the raw liquid is subjected to a high-temperature reaction, and the trixylene phosphate is heated and distilled, and precipitated reactants appear in the raw liquid. If these precipitated reactants are not treated, they will precipitate at the bottom of the distillation device during the distillation process and cause crystallization into blocks, which is inconvenient for the subsequent distillation device to perform distillation operations.

[0004] To this end, the present invention provides a distillation device for preparing trixylene phosphate. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: a distillation device for preparing trixylene phosphate described in the present invention comprises a bottom plate, a slag removal box is fixedly installed on the top of the bottom plate, a tank body is fixedly installed on the top of the slag removal box, a liquid inlet pipe port is fixedly installed on the top of the tank body, a liquid storage box is fixedly installed on the bottom of the slag removal box, a distillation cylinder is arranged inside the tank body, the distillation cylinder is placed just above the liquid storage box, one end of the liquid inlet pipe port is fixedly connected to the top of the distillation cylinder, an anti-sinking component is arranged inside the distillation cylinder, the anti-sinking component is used to prevent the reaction precipitate generated by the raw liquid placed in the distillation cylinder during distillation from precipitating at the bottom of the distillation device to cause crystallization and block formation, and a filter residue component is arranged inside the slag removal box, the filter residue component is used to filter out the reaction precipitate in the raw liquid after distillation; The method is to pass a raw liquid containing trixylene phosphate into a distillation cylinder from a liquid inlet pipe, heat the distillation cylinder for distillation, and distill out the trixylene phosphate in the raw liquid. During distillation, an anti-settling component in the distillation cylinder stirs and shakes the raw liquid to prevent reaction precipitates generated by the raw liquid placed in the distillation cylinder during distillation from settling at the bottom of the distillation device to form crystals and blocks, thereby preventing agglomeration. At the same time, stirring the raw liquid can speed up the distillation speed, which is more conducive to the preparation of trixylene phosphate. When the raw liquid is distilled, a filter residue component in a slag removal box filters out the reaction precipitates in the raw liquid after distillation, thereby filtering the precipitates and preventing the raw liquid from containing reaction precipitates that are not conducive to the subsequent preparation of the raw liquid.

[0007] Preferably, the anti-settling component includes a shaft rod, which is placed inside a distillation cylinder. A motor is fixedly installed at the bottom of the distillation cylinder, one end of the shaft rod is fixedly connected to the output end of the motor, and a stirring plate is fixedly installed on the outer wall of the shaft rod. When the raw liquid is distilled in the distillation cylinder, the motor drives the stirring plate to rotate through the shaft rod, and the stirring plate stirs the raw liquid. On the one hand, the distillation speed of the raw liquid can be accelerated, and on the other hand, the precipitate generated by the distillation of the raw liquid will not adhere to the inner wall of the distillation cylinder, thereby avoiding the crystallization of the precipitate on the inner wall of the distillation cylinder.

When the shaft rod rotates, the rotation of the shaft rod drives the circular plate to squeeze the return spring to move at the bottom of the distillation cylinder, and the elastic force of the return spring causes the circular plate to shake at the bottom of the distillation cylinder. When the circular plate shakes, the raw liquid on the top of the circular plate will shake, preventing the reaction precipitate in the raw liquid from falling on the top of the circular plate and forming an adsorption relationship with the circular plate, causing the reaction precipitate to crystallize on the top of the circular plate, thereby vibrating the raw liquid. Vibrating the raw liquid can also speed up the heat transfer speed in the raw liquid, thereby speeding up the distillation speed.

A plurality of liquid outlets are provided at the bottom of the distillation cylinder. When the distillation of the raw liquid is completed, the liquid blocking ring block in the limiting flow ring box is driven to slide upward from the bottom of the distillation cylinder. When the liquid blocking ring block moves to a certain position, the liquid outlet at the bottom of the distillation cylinder is exposed, and the raw liquid placed in the distillation cylinder will flow out from the liquid outlet into the limiting flow ring box, and finally flow into the liquid storage tank through the setting of the path. The setting of the liquid blocking ring block can play a role in blocking the flow of the raw liquid.

[0011] Preferably, telescopic cylinders are symmetrically fixedly installed on the bottom of the inner wall of the tank body, ring plates are fixedly installed on the tops of the two telescopic cylinders, and multiple lifting rods are fixedly installed on the top of the liquid-blocking ring block, one ends of the multiple lifting rods are fixedly connected to the top of the ring plate. When the liquid-blocking ring block is moved, the ring plate is pushed up by the telescopic cylinder, and when the ring plate moves up, the liquid-blocking ring block is driven to move upward from the bottom of the distillation cylinder through the lifting rods, so that the liquid outlet at the bottom of the distillation cylinder is opened, and the original liquid in the distillation cylinder will flow out of the distillation cylinder, thereby controlling the movement of the liquid-blocking ring block.

[0012] Preferably, a limit ring is fixedly installed on the bottom of the tank body, and a clamping frame is symmetrically installed on the bottom of the ring plate, and a filtrate plate is fixedly installed between the two clamping frames. When the telescopic cylinder drives the ring plate to move up, the telescopic cylinder drives the two clamping frames to move up through the ring plate, and the filtrate plate placed between the two clamping frames will be driven to move upward. When the ring plate drives the liquid blocking ring block to move to a certain position, the ring plate drives the filtrate plate to be placed on the bottom of the limit ring through the clamping frame, and fits with the bottom inner wall of the limit ring. The raw liquid flows out from the liquid outlet and passes through the filtrate plate. The reaction precipitate of the raw liquid will be filtered by the filtrate plate and placed on the top of the filtrate plate, thereby filtering the precipitate.

[0013] Preferably, the filter residue assembly includes a rotating cylinder, the output shaft of the rotating cylinder is fixedly installed with a screw shaft, the outer wall of the screw shaft is slidably connected with a shifting rod block, the inner wall of the shifting rod block is fixedly installed with a slag pushing rod, the slag pushing rod is slidably connected to the top of the filtrate plate, when the raw liquid completely enters the liquid storage box through the filtrate plate, the telescopic cylinder drives the liquid blocking ring block and the filtrate plate to reset, and then new raw liquid is introduced through the liquid inlet pipe to continue the distillation operation, at the same time, the rotating cylinder drives the screw shaft to rotate, thereby driving the slag pushing rod to move through the shifting rod block, and when the slag pushing rod moves, the slag pushing rod pushes the filter residue placed on the filtrate plate, pushes it out of the top of the filtrate plate, to prevent excessive filter residue on the filtrate plate from accumulating and affecting the subsequent filtration effect.

[0014] Preferably, a partition is symmetrically fixedly installed on the outer wall of the limiting ring. Through the setting of the partition, the partition divides the slag removal box into two parts, one part for operation and the other part for slag storage.

[0015] Preferably, a liquid receiving plate is fixedly installed on the outer wall of the distillation cylinder, a plurality of distillation ports are opened on the top of the distillation cylinder, and an arc flow plate is fixedly installed on the top of the inner wall of the tank body, so that trixylene phosphate flows out from the distillation port on the top of the distillation cylinder in gaseous form, and then the gas is placed under the arc flow plate through the floating of the trixylene phosphate gas. Through the arc-shaped setting of the arc flow plate, when the trixylene phosphate gas accumulates on the arc flow plate to a certain extent, the gas becomes liquid and flows along the arc surface of the arc flow plate to the top of the liquid receiving plate for collection, thereby collecting the trixylene phosphate.

[0016] The beneficial effects of the present invention are as follows: 1. The distillation device for preparing trixylene phosphate described in the present invention uses a motor to drive a stirring plate to stir the stock solution, which can accelerate the distillation speed of the stock solution on the one hand, and prevent the precipitate generated by the distillation of the stock solution from adhering to the inner wall of the distillation cylinder on the other hand. At the same time, the stirring plate squeezes the circular plate downward, and the elastic force of the reset spring causes the circular plate to vibrate at the bottom of the distillation cylinder, preventing the reaction precipitate in the stock solution from falling on the top of the circular plate and forming an adsorption relationship with the circular plate, resulting in the reaction precipitate crystallizing on the top of the circular plate. The heat transfer speed in the stock solution can also be accelerated by vibrating the stock solution, thereby accelerating the distillation speed.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 8 As shown, a distillation device for preparing trixylene phosphate according to an embodiment of the present invention comprises a bottom plate 29, a slag removal box 2 is fixedly installed on the top of the bottom plate 29, a tank body 1 is fixedly installed on the top of the slag removal box 2, a liquid inlet pipe port 4 is fixedly installed on the top of the tank body 1, a liquid storage box 3 is fixedly installed on the bottom of the slag removal box 2, a distillation cylinder 7 is arranged inside the tank body 1, the distillation cylinder 7 is placed just above the liquid storage box 3, one end of the liquid inlet pipe port 4 is fixedly connected to the top of the distillation cylinder 7, an anti-settling component is arranged inside the distillation cylinder 7, the anti-settling component is used to prevent the reaction precipitate generated by the raw liquid placed in the distillation cylinder 7 during distillation from settling at the bottom of the distillation device to cause crystallization and block formation, and a filter residue component is arranged inside the slag removal box 2, the filter residue component is used to filter out the reaction precipitate in the raw liquid after distillation; In the current prior art, when preparing and distilling trixylene phosphate, the stock solution is subjected to a high-temperature reaction, and the trixylene phosphate is heated and distilled, and precipitated reactants appear in the stock solution. If these precipitated reactants are not treated, they will precipitate at the bottom of the distillation device during the distillation process, causing crystallization and agglomeration, which is inconvenient for the subsequent distillation device to perform distillation operations; The raw liquid containing trixylene phosphate is introduced into the distillation cylinder 7 from the liquid inlet port 4, and the distillation cylinder 7 is heated to distill the trixylene phosphate in the raw liquid. During distillation, the anti-settling component in the distillation cylinder 7 stirs and shakes the raw liquid to prevent the reaction precipitate generated by the raw liquid placed in the distillation cylinder 7 from settling at the bottom of the distillation device to form crystal blocks, thereby playing an anti-caking role. At the same time, the distillation speed can be accelerated by stirring the raw liquid, which is more conducive to the preparation of trixylene phosphate. When the raw liquid is distilled, the filter residue component in the slag removal box 2 will distill the residue. The reaction precipitate in the subsequent raw liquid is filtered out, which plays the role of filtering the precipitate, preventing the raw liquid from containing the reaction precipitate, which is not conducive to the subsequent preparation of the raw liquid. The filter residue component and the anti-precipitation component cooperate with each other to solve the problem in the current prior art that when preparing and distilling trixylene phosphate, the raw liquid is subjected to a high-temperature reaction, and the trixylene phosphate is heated and distilled, and precipitated reactants appear in the raw liquid. If these precipitated reactants are not processed, they will precipitate at the bottom of the distillation device during the distillation process to cause crystallization and block formation, which is not convenient for the subsequent distillation device to perform distillation operations.

[0024] like Figures 3 to 6 As shown, the anti-sinking assembly includes a shaft 11, which is placed inside the distillation cylinder 7, a motor 20 is fixedly installed at the bottom of the distillation cylinder 7, one end of the shaft 11 is fixedly connected to the output end of the motor 20, and a stirring plate 10 is fixedly installed on the outer wall of the shaft 11; When the raw liquid is distilled in the distillation cylinder 7, the motor 20 drives the stirring plate 10 to rotate through the shaft 11. The stirring plate 10 stirs the raw liquid. On the one hand, it can speed up the distillation speed of the raw liquid. On the other hand, it can prevent the precipitate produced by the distillation of the raw liquid from adhering to the inner wall of the distillation cylinder 7, and avoid the crystallization of the precipitate on the inner wall of the distillation cylinder 7. It should be noted here that the outer side of the stirring plate 10 rotates and scrapes with the inner wall of the distillation cylinder 7, and the outer side of the stirring plate 10 is shaped like a side knife.

[0025] like Figure 6 to Figure 7 As shown, a circular plate 23 is provided at the bottom of the distillation cylinder 7, a plurality of slide bars 24 are fixedly installed at the bottom of the circular plate 23, a plurality of return springs 25 are provided between the circular plate 23 and the distillation cylinder 7, the plurality of return springs 25 are respectively placed outside the plurality of slide bars 24, and the outer walls of the plurality of slide bars 24 are all slidably connected with the inner wall of the distillation cylinder 7; When the shaft 11 rotates, the rotation of the shaft 11 drives the circular plate 23 to squeeze the reset spring 25 and move at the bottom of the distillation cylinder 7. The elastic force of the reset spring 25 causes the circular plate 23 to shake at the bottom of the distillation cylinder 7. When the circular plate 23 shakes, the raw liquid on the top of the circular plate 23 will shake, preventing the reaction precipitate in the raw liquid from falling on the top of the circular plate 23 and being adsorbed by the circular plate 23, causing the reaction precipitate to crystallize on the top of the circular plate 23, thereby vibrating the raw liquid. By vibrating the raw liquid, the heat transfer speed in the raw liquid can also be accelerated, thereby accelerating the distillation speed.

[0026] like Figure 6 to Figure 7 As shown, three protrusions 21 are fixedly mounted on the top of the circular plate 23, and the bottom of the stirring plate 10 is slidably connected to the top of the three protrusions 21; When the shaft 11 rotates, the bottom of the shaft 11 squeezes the protrusion 21 on the circular plate 23 to rotate. When the protrusion 21 is pressed downward, it pushes the circular plate 23 to squeeze the return spring 25, thereby achieving the vibration of the circular plate 23, playing the role of squeezing vibration. It should be noted here that the bottom of the stirring plate 10 should scrape the top of the protrusion 21.

[0027] like Figure 3 to Figure 4 As shown, a flow limiting ring box 19 is fixedly installed in the middle of the tank body 1, and the flow limiting ring box 19 is placed outside the distillation cylinder 7. A liquid blocking ring block 18 is arranged inside the distillation cylinder 7. The inner side of the liquid blocking ring block 18 is slidably connected to the outer wall of the distillation cylinder 7, and the outer side of the liquid blocking ring block 18 is slidably connected to the inner wall of the flow limiting ring box 19. A plurality of liquid outlets 22 are provided at the bottom of the distillation cylinder 7. When the distillation of the raw liquid is completed, the liquid blocking ring block 18 in the flow limiting ring box 19 is driven to slide upward from the bottom of the distillation cylinder 7. When the liquid blocking ring block 18 moves to a certain position, the liquid outlet 22 at the bottom of the distillation cylinder 7 is exposed, and the raw liquid placed in the distillation cylinder 7 will flow out from the liquid outlet 22 into the flow limiting ring box 19, and finally flow into the liquid storage tank 3 through the setting of the path. The setting of the liquid blocking ring block 18 plays a role in blocking the flow of the raw liquid.

[0028] like Figure 3 to Figure 4 As shown, telescopic cylinders 15 are symmetrically fixedly installed on the bottom of the inner wall of the tank body 1, and ring plates 16 are fixedly installed on the tops of the two telescopic cylinders 15. A plurality of lifting rods 17 are fixedly installed on the top of the liquid blocking ring block 18, and one end of the plurality of lifting rods 17 is fixedly connected to the top of the ring plate 16; When the liquid blocking ring block 18 is moved, the ring plate 16 is pushed upward by the telescopic cylinder 15. When the ring plate 16 moves upward, the liquid blocking ring block 18 is driven to move upward from the bottom of the distillation cylinder 7 through the lifting rod 17, so that the liquid outlet 22 at the bottom of the distillation cylinder 7 is opened, and the original liquid in the distillation cylinder 7 will flow out of the distillation cylinder 7, which plays a role in controlling the movement of the liquid blocking ring block 18.

[0029] like Figures 4 to 5As shown, a limit ring 14 is fixedly installed at the bottom of the tank body 1, and a plywood frame 13 is symmetrically installed at the bottom of the ring plate 16, and a filtrate plate 12 is fixedly installed between the two plywood frames 13; When the telescopic cylinder 15 drives the ring plate 16 to move upward, the telescopic cylinder 15 drives the two clamping frames 13 to move upward through the ring plate 16, and the filtrate plate 12 placed between the two clamping frames 13 will be driven to move upward. When the ring plate 16 drives the liquid blocking ring block 18 to move to a certain position, the ring plate 16 drives the filtrate plate 12 to be placed at the bottom of the limit ring 14 through the clamping frame 13, and fits with the bottom inner wall of the limit ring 14. The raw liquid flows out from the liquid outlet 22 and passes through the filtrate plate 12. The reaction precipitate of the raw liquid will be filtered by the filtrate plate 12 and placed on the top of the filtrate plate 12, thereby filtering the precipitate.

[0030] like Figures 7 and 8 As shown, the filter residue assembly includes a rotary cylinder 26, the output shaft of the rotary cylinder 26 is fixedly mounted with a screw shaft 8, the outer wall of the screw shaft 8 is slidably connected with a shifting rod block 28, the inner wall of the shifting rod block 28 is fixedly mounted with a slag pusher 27, and the slag pusher 27 is slidably connected to the top of the filtrate plate 12; When the raw liquid completely enters the liquid storage box 3 through the filtrate plate 12, the telescopic cylinder 15 drives the liquid blocking ring block 18 and the filtrate plate 12 to reset, and then new raw liquid is introduced through the liquid inlet pipe 4 to continue the distillation operation. At the same time, the rotating cylinder 26 drives the screw shaft 8 to rotate, thereby driving the slag pushing rod 27 to move through the moving rod block 28. When the slag pushing rod 27 moves, the slag pushing rod 27 pushes the filter residue on the filtrate plate 12 and pushes it out of the top of the filtrate plate 12 to prevent excessive accumulation of filter residue on the filtrate plate 12, affecting the subsequent filtering effect. It should be noted here that the outer shape of the slag pushing rod 27 is designed as a semi-arc push plate. Through this outer shape design, the filter residue will be gathered together when it is pushed for easy collection. The design length of the slag pushing rod 27 and the screw shaft 8 should be greater than the diameter length of the filtrate plate 12.

[0031] like Figure 1 to Figure 2 As shown, a partition plate 30 is symmetrically fixedly mounted on the outer wall of the limiting ring 14; During operation, the partition 30 is arranged to separate the slag removal box 2 into two parts, one for operation and the other for slag storage. The filter residue pushed by the slag pushing rod 27 will be pushed into the slag storage part for collection.

[0032] like Figures 2 to 3 As shown, a liquid placing plate 6 is fixedly installed on the outer wall of the distillation cylinder 7, a plurality of distillation ports 9 are opened on the top of the distillation cylinder 7, and an arc flow plate 5 is fixedly installed on the top of the inner wall of the tank body 1; During distillation, trixylene phosphate flows out from the distillation port 9 at the top of the distillation cylinder 7 in the form of gas, and then the gas is placed under the arc flow plate 5 due to the floating of the trixylene phosphate gas. Through the arc-shaped setting of the arc flow plate 5, when the trixylene phosphate gas accumulates on the arc flow plate 5 to a certain extent, the gas becomes liquid and flows along the arc surface of the arc flow plate 5 to the top of the liquid placing plate 6 for collection, thereby collecting the trixylene phosphate.

[0033] Working principle: a stock solution containing trixylene phosphate is passed into a distillation cylinder 7 from a liquid inlet port 4, and the distillation cylinder 7 is heated to distill the trixylene phosphate in the stock solution. During distillation, an anti-settling component in the distillation cylinder 7 stirs and shakes the stock solution to prevent the reaction precipitate generated by the stock solution placed in the distillation cylinder 7 from settling at the bottom of the distillation device to form crystal blocks during distillation, thereby playing an anti-caking role. At the same time, the distillation speed can be accelerated by stirring the stock solution, which is more conducive to the preparation of trixylene phosphate. When the distillation of the stock solution is completed, the filter residue component in the slag removal box 2 filters out the reaction precipitate in the distilled stock solution, thereby playing a role of filtering the precipitate, thereby preventing the stock solution from containing the reaction precipitate, which is not conducive to the subsequent preparation of the stock solution. When the stock solution is distilled in the distillation cylinder 7, the motor 20 drives the stirring plate 10 to rotate through the shaft 11, and the stirring plate 10 stirs the stock solution, which can accelerate the distillation speed of the stock solution on the one hand, and prevent the precipitate generated by the distillation of the stock solution from adhering to the inner wall of the distillation cylinder 7 on the other hand, and avoid the precipitate from crystallizing on the inner wall of the distillation cylinder 7; When the shaft 11 rotates, the rotation of the shaft 11 drives the circular plate 23 to squeeze the reset spring 25 and move at the bottom of the distillation cylinder 7. The elastic force of the reset spring 25 causes the circular plate 23 to shake at the bottom of the distillation cylinder 7. When the circular plate 23 shakes, the raw liquid on the top of the circular plate 23 will shake, preventing the reaction precipitate in the raw liquid from falling on the top of the circular plate 23 and forming an adsorption relationship with the circular plate 23, causing the reaction precipitate to crystallize on the top of the circular plate 23, thereby vibrating the raw liquid. Vibrating the raw liquid can also speed up the heat transfer speed in the raw liquid, thereby speeding up the distillation speed. When the shaft 11 rotates, the bottom of the shaft 11 squeezes the protrusion 21 on the circular plate 23 to rotate, and when the protrusion 21 is pressed downward, it pushes the circular plate 23 to squeeze the return spring 25, thereby achieving the vibration of the circular plate 23, playing the role of squeezing vibration; When the distillation of the raw liquid is completed, the liquid blocking ring block 18 in the flow limiting ring box 19 is driven to slide upward from the bottom of the distillation cylinder 7. When the liquid blocking ring block 18 moves to a certain position, the liquid outlet 22 at the bottom of the distillation cylinder 7 is exposed, and the raw liquid placed in the distillation cylinder 7 will flow out from the liquid outlet 22 into the flow limiting ring box 19, and finally flow into the liquid storage box 3 through the setting of the path. The setting of the liquid blocking ring block 18 plays a role in blocking the flow of the raw liquid. When the liquid blocking ring block 18 is moved, the ring plate 16 is pushed upward by the telescopic cylinder 15. When the ring plate 16 is moved upward, the lifting rod 17 drives the liquid blocking ring block 18 to move upward from the bottom of the distillation cylinder 7, so that the liquid outlet 22 at the bottom of the distillation cylinder 7 is opened, and the original liquid in the distillation cylinder 7 will flow out of the distillation cylinder 7, which plays a role in controlling the movement of the liquid blocking ring block 18; When the telescopic cylinder 15 drives the ring plate 16 to move upward, the telescopic cylinder 15 drives the two clamping frames 13 to move upward through the ring plate 16, and the filtrate plate 12 placed between the two clamping frames 13 will be driven to move upward. When the ring plate 16 drives the liquid blocking ring block 18 to move to a certain position, the ring plate 16 drives the filtrate plate 12 to be placed at the bottom of the limit ring 14 through the clamping frame 13, and fits with the bottom inner wall of the limit ring 14. The raw liquid flows out from the liquid outlet 22 and passes through the filtrate plate 12. The reaction precipitate of the raw liquid will be filtered by the filtrate plate 12 and placed on the top of the filtrate plate 12, playing the role of filtering the precipitate. When the stock liquid completely enters the liquid storage box 3 through the filtrate plate 12, the telescopic cylinder 15 drives the liquid blocking ring block 18 and the filtrate plate 12 to reset, and then new stock liquid is introduced through the liquid inlet pipe 4 to continue the distillation operation. At the same time, the rotating cylinder 26 drives the screw shaft 8 to rotate, thereby driving the slag pushing rod 27 to move through the moving rod block 28. When the slag pushing rod 27 moves, the slag pushing rod 27 pushes the filter residue on the filtrate plate 12 and pushes it out of the top of the filtrate plate 12 to prevent the filter residue on the filtrate plate 12 from being excessively accumulated and affecting the subsequent filtering effect. During operation, the partition 30 is arranged to separate the slag removal box 2 into two parts, one for operation and the other for slag storage. The filter residue pushed by the slag pushing rod 27 will be pushed into the slag storage part for collection. During distillation, trixylene phosphate flows out from the distillation port 9 at the top of the distillation cylinder 7 in the form of gas, and then the gas is placed under the arc flow plate 5 due to the floating of the trixylene phosphate gas. Through the arc-shaped setting of the arc flow plate 5, when the trixylene phosphate gas accumulates on the arc flow plate 5 to a certain extent, the gas becomes liquid and flows along the arc surface of the arc flow plate 5 to the top of the liquid placing plate 6 for collection, thereby collecting the trixylene phosphate.
