Description

Technical Field

[0001] The invention relates to the technical field of triethyl phosphate material preparation, and in particular to a preparation system and process for triethyl phosphate material. Background Art

[0002] Triethyl phosphate is a colorless, transparent liquid with a slight fruity aroma. It is soluble in water and easily soluble in organic solvents such as ethanol and ethyl ether benzene. Triethyl phosphate is stable at room temperature and slowly hydrolyzes when heated. It is a high-boiling point solvent and is often used as a plasticizer for rubber and plastics. It is also used as a raw material for the preparation of pesticides and insecticides. The preparation process generally involves esterification, dealcoholization to remove hydrogen chloride, distillation separation, and hydrogen chloride absorption. Finally, these impurities are removed to obtain a triethyl phosphate product with a higher purity. The volatile gas contacts the exhaust gas through the water film formed on the filler in the spray tower, and is then absorbed and treated.

[0003] However, in actual use, the inventors found that the production of triethyl phosphate is often accompanied by the generation of some volatile harmful gases, which are collected and processed in the spray tower by combining with water. However, the absorption efficiency of the spray tower for volatile gases gradually decreases under long-term working conditions, which leads to the problem of substandard waste gas emissions during the production of triethyl phosphate.

During the process, the guide component lifts the circulating water and turns it in a spiral manner, thereby continuously entraining the waste gas to contact with the circulating water for initial absorption, and the rotation of the circulating water drives the input waste gas to rise in a spiral shape, changing the gas walking path, thereby promoting the full reaction and absorption of volatile gases; Step 2, gas absorption process, when the waste gas rises, the spray tower sprays the circulating water by top spraying, and the water mist formed by the spraying forms a water film on the adsorption element, thereby increasing the reaction area, so that the waste gas is fully contacted with the water film for absorption; Step 3, recycling process, during the absorption process, the stirring component in the mobilization component continuously stirs the upper and lower layers of adsorbents, so that the upper layer of adsorbents falls to the lower layer position, and at the same time, the adsorbents at the bottom of the lower layer are driven by the conveying component and the recycling component to return from the lower layer to the upper layer position, thereby completing the cycle; Step 4, cleaning process, during the recycling process, the adsorbent is first adjusted in position by the reuse component, and then the cleaning component is cleaned by squeezing and flushing, and then the adsorbent is separated and output and the wastewater is discharged by the output component.

This changes the cleaning method in which the traditional filler can only rely on water mist to accumulate in itself and then automatically fall by gravity, thereby improving the adsorption effect of volatile gases; (2) In the present invention, the stirring component, the conveying component and the recycling component in the transfer mechanism are arranged so that the adsorbent is arranged in two layers. During the working process, the adsorbent in the bottom layer that is in contact with the volatile gas more is continuously used in the upper layer, thereby forming a cycle of the upper and lower layers, ensuring that the adsorption capacity of the bottom adsorbent is not reduced too much, thereby improving the overall adsorption effect and ensuring that the exhaust gas meets the emission standards; (3) In the present invention, by providing a recycling component, a cleaning component and an output component in the mobilization mechanism, the bottom adsorbent is squeezed and rinsed during recycling to completely renew its own water film, and has the most effective adsorption state during output. The waste water for cleaning the adsorbent is discharged separately to prevent it from contacting the adsorbent again, thereby reducing the pressure of the overall adsorption work; (4) In the present invention, by providing a guiding component in the auxiliary mechanism, the circulating water continuously carries the waste gas to contact with itself for initial absorption, and the rotation of the circulating water drives the input waste gas to rise in a spiral shape, thereby changing the gas path and promoting the full reaction and absorption of the volatile gas.

[0016] In summary, the equipment has the advantages of good reaction waste gas absorption effect, high adsorption efficiency, and stable waste gas treatment state after long-term use, and is particularly suitable for the technical field of triethyl phosphate material preparation.

[0040] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0041] Embodiment 1 like Figures 1 to 5 As shown, a preparation system for triethyl phosphate material comprises: A reaction mechanism 1, wherein the reaction mechanism 1 comprises a plurality of adsorbents 11 disposed in a spray tower 100 and used for absorbing exhaust gas; A regulating mechanism 2, which is disposed in the spray tower 100 and is used to cooperate with the adsorbent 11 to improve the efficiency of exhaust gas absorption; An auxiliary mechanism 3, which is disposed in the spray tower 100 and is used for initially absorbing the exhaust gas; The adsorption member 11 includes a first adsorption ring 111 and a second adsorption ring 112 which are nested with each other, an elastic sheet 113 whose two ends are respectively connected to the first adsorption ring 111 and the second adsorption ring 112, a first wiper ring 114 connected to the first adsorption ring 111, a second wiper ring 115 connected to the second adsorption ring 112, and a first magnet 117 connected to the bottom of the first adsorption ring 111 via an arc sheet 116.

[0042] In this embodiment, an adsorbent 11 is provided in the reaction mechanism 1 so that the water film on the surface of the adsorbent 11 can be quickly scraped off under the action of an external force, thereby completely renewing its own water film to prevent volatile gases from remaining in itself. This changes the cleaning method in which the traditional filler itself can only rely on the accumulation of water mist in itself and then automatically falls by gravity, thereby improving the adsorption effect of volatile gases.

[0043] In detail, after the exhaust gas enters the spray tower 100, the exhaust gas reacts with the water film formed on the reaction mechanism 1 through water mist spraying, and then the exhaust gas is absorbed. Then, under the action of the mobilization mechanism 2, the reaction mechanism 1 as a whole realizes the upper and lower position circulation to ensure the adsorption effect of the reaction mechanism 1. During the process, the auxiliary mechanism 3 performs preliminary absorption and path guidance of the gas at the bottom of the spray tower 100 and scrapes off the liquid that may remain on the inner wall of the intake pipe 200.

[0044] Further, if Figures 1 to 19 As shown, the mobilization mechanism 2 includes a stirring assembly 21 arranged on the spray tower 100 and used to receive multiple adsorbents 11, a conveying assembly 22 arranged on the spray tower 100 and used to collect the adsorbents 11, a recycling assembly 23 arranged on the stirring assembly 21 and used to recycle the adsorbents 11, a cleaning assembly 24 arranged on the stirring assembly 21 and used to clean the adsorbents 11, and an output assembly 25 arranged on the cleaning assembly 24 and used to drive the adsorbents 11 to output.

[0045] In this embodiment, by providing the adjusting mechanism 2, the original situation in which the filler in the spray tower 100 can only statically absorb the exhaust gas is changed. Through the circulation of the upper and lower layers of the adsorption components 11, the overall adsorption effect of the reaction mechanism 1 is effectively guaranteed, and the adsorption components 11 can also be driven to undergo a certain degree of change during the circulation process, thereby accelerating the renewal of its own water film and preventing the residue of exhaust gas solutes.

[0046] In detail, during the operation of the spray tower 100, the stirring component 21 continuously stirs the bottom of the upper and lower layers of the adsorbent 11, so that the bottom part of the upper adsorbent 11 can complete the fall from the upper layer to the lower layer, and the adsorbent 11 on the bottom part of the lower layer is also sent to the recycling component 23 in batches under the action of the conveying component 22. Then the recycling component 23 cooperates with the cleaning component 24 to update the water film on the surface of the adsorbent 11, and finally dispersed to the upper layer by the output component 25 to complete the cycle.

[0047] Further, if Figures 2 to 3 and Figures 6 to 8 As shown, the stirring assembly 21 includes a first filter plate 212 connected to the spray tower 100 and provided with a material drop trough 211 for holding the adsorbent 11, a transmission pipe 213 connected to the first filter plate 212, a motor 215 connected to the spray tower 100 and having a driving rod 214 connected to the output end, a second filter plate 217 connected to the spray tower 100 and connected to the driving rod 214 through a bracket 216, a driving ring 218 connected to the output end of the motor 215, a first stirring rod 219 connected to the driving ring 218 and located on the surface of the first filter plate 212, and a second stirring rod 2110 connected to the transmission pipe 213 and located on the surface of the second filter plate 217.

[0048] In this embodiment, by providing a stirring component 21, the upper and lower layers of adsorbents 11 are changed from traditional static absorption to dynamic absorption. During the stirring process, due to the elastic setting of the adsorbent 11 itself, the water film of the adsorbent 11 itself is not only affected by gravity, but also includes vibration during stirring, mutual collision and impact from the upper layer to the lower layer, thereby making the renewal speed of the water film faster and improving the adsorption effect.

[0049] In detail, when the spray tower 100 is working, water mist falls on the surfaces of the first adsorption ring 111 and the second adsorption ring 112 and forms a water film for adsorbing the exhaust gas. When the exhaust gas rises from the bottom of the spray tower 100, it contacts the water film and is absorbed. During the process, the motor 215 drives the driving rod 214 to rotate through the output end, and at the same time drives the first stirring rod 219 to rotate on the first filter plate 212 through the driving ring 218. The driving rod 214 drives the second filter plate 217 to rotate through the bracket 216, so that the upper and lower layers of the adsorption components 11 are in a dynamic adsorption state.

[0050] It should be noted that the first filter plate 212, the second filter plate 217 and the bottom of the transmission pipe 213 are all provided with leakage holes which are not shown in the figure. The transmission pipe 213, the first filter plate 212 and the second stirring rod 2110 are fixedly connected to each other and to the inner wall of the spray tower 100.

[0051] Further, if Figure 1 and Figures 7 to 9 As shown, the conveying assembly 22 includes a mounting frame 221 disposed on the spray tower 100, a rotating rod 222 connected to the mounting frame 221 and having one end passing through the spray tower 100, a driving gear 223 connected to the rotating rod 222, a driving rack 224 connected to the driving ring 218 and meshing with the driving gear 223 for transmission, a first reciprocating screw rod 225 connected to the mounting frame 221, a driving plate 226 connected to the mounting frame 221 and connected to the first reciprocating screw rod 225, and two ends of the driving plate 226 connected to the mounting frame 221 and connected to the first reciprocating screw rod 225. The first reciprocating screw 225 and the belt transmission part 227 on the rotating rod 222, the conveying plate 229 that passes through the spray tower 100 and is connected to the spray tower 100 through the first telescopic part 228, the conveying port 2210 opened on the transmission pipe 213, two groups of door panels 2212 connected to the conveying port 2210 through the rotating shaft 2211, the first gear 2213 connected to the rotating shaft 2211 and two groups of first racks 2214 connected to the driving plate 226 and meshing with the first gear 2213 for transmission.

[0052] In this embodiment, by setting up the conveying component 22, the adsorption component 11 of the lower layer is conveyed to the position of the recycling component 23, thereby completing the circulation from the lower layer to the upper layer. At the same time, the first rack 2214 is set deeper than the conveying plate 229, so that after the conveying port 2210 on the transmission tube 213 is opened, the conveying plate 229 can convey the adsorption component 11 into the transmission tube 213, and when resetting, the door plate 2212 rotates outward from the inside of the transmission tube 213 and closes, which effectively prevents the excess adsorption component 11 from getting stuck at the conveying port 2210.

[0053] In detail, when the motor 215 drives the stirring assembly 21 to work, the driving rack 224 on the driving ring 218 intermittently drives the driving gear 223 to rotate, and the driving gear 223 drives the first reciprocating screw rod 225 to rotate through the rotating rod 222 and the belt transmission member 227. The driving plate 226 connected to the first reciprocating screw rod 225 first drives the first rack 2214 to move toward the top of the transmission tube 213, and then when the first rack 2214 drives the first gear 2213 to rotate, the rotating shaft 2211 drives the door plate 2212 to open inward, and then the driving plate 226 squeezes the conveying plate 229 to move, and pushes the lower bottom part of the adsorption member 11 to enter the inside of the transmission tube 213 through the conveying port 2210. When resetting, the driving plate 226 cancels the squeezing of the conveying plate 229, and the conveying plate 229 is reset under the action of the first telescopic member 228, and then the first rack 2214 drives the first gear 2213 to reverse, and the door plate 2212 is closed.

[0054] It should be noted that the number of adsorbents 11 transported to the recycling component 23 by the conveying plate 229 is determined by its own volume, but there is a possibility of mutual squeezing and accidentally entering the transmission pipe 213. Therefore, the volume of the conveying plate 229 is controlled so that the number transported each time is less than the number that the recycling component 23 can carry.

[0055] Further, if Figures 6 to 14As shown, the recycling assembly 23 includes a second reciprocating screw rod 231 sleeved on the driving rod 214, a first bottom plate 232 connected to the transmission tube 213, a first internally threaded rod 233 connected to the second reciprocating screw rod 231 and connected to the first bottom plate 232, a second bottom plate 235 connected to the transmission tube 213 and connected to the first bottom plate 232 via a first spring 234, a third bottom plate 237 connected to the transmission tube 213 and connected to the second bottom plate 235 via a second spring 236, and a third bottom plate 238 opened on the third bottom plate 239. An annular groove 238 on the plate 237, a plurality of limiting columns 2310 connected to the second base plate 235 and provided with a second magnet 239, a limiting hole 2311 opened at the bottom of the third base plate 237 and cooperating with the limiting columns 2310 to fix the position of the third base plate 237, a plurality of first intercepting blocks 2313 embedded in the spray tower 100 and connected to the spray tower 100 through a third spring 2312, and a second intercepting block 2315 embedded in the spray tower 100 and connected to the spray tower 100 through a fourth spring 2314.

[0056] In this embodiment, by setting the first interception block 2313 and the second interception block 2315 in the recycling component 23, the adsorbent 11 located on the recycling component 23 undergoes two sets of vibrations front and back. The first set of vibrations is performed multiple times in order to evenly distribute the multiple adsorbents 11, and the second set of vibrations is used to fix the position of the adsorbent 11 to facilitate subsequent cleaning and output work.

[0057] In detail, when the driving rod 214 rotates, the second reciprocating screw rod 231 connected to the driving rod 214 and the first internal threaded rod 233 connected to the first bottom plate 232 cooperate to drive the first bottom plate 232 to move upward, and the first bottom plate 232, the second bottom plate 235 and the third bottom plate 237 move upward together through the connection of the first spring 234 and the second spring 236. During the process, when the third bottom plate 237 contacts the first interception block 2313 multiple times, the third bottom plate 237 is blocked by the elastic force of the third spring 2312, and the second spring 236 shrinks accordingly. When the second spring 236 shrinks to a certain extent, the elastic force causes the third bottom plate 237 to pass over the first interception block 2313, and the second spring 236 quickly resets, thereby driving the multiple adsorption members 11 on the third bottom plate 237 to vibrate evenly in the annular groove 238. Due to the first magnet 117 set at the bottom of the adsorption member 11, the entire adsorption member 11 stands on the third bottom plate 237 like a tumbler. Then, the third bottom plate 237 continues to move and contacts and squeezes the second intercepting block 2315. This time, under the elastic force of the fourth spring 2314, the second spring 236 is fully compressed and cannot make the third bottom plate 237 pass over the second intercepting block 2315. At the same time, when the second bottom plate 235 drives the second spring 236 to be compressed, the limiting column 2310 located on the second bottom plate 235 is inserted into the limiting hole 2311 at the bottom of the first bottom plate 232. At this time, the first bottom plate 232 and the second bottom plate 235 are connected as one. As the first bottom plate 232 continues to move, the first spring 234 contracts and brings elastic force to make the third bottom plate 237 pass over the second intercepting block 2315. At the same time, when the first spring 234 is reset, the adsorbent 11 on the third bottom plate 237 vibrates evenly again. This time, since the second bottom plate 235 is combined with the first bottom plate 232, the second magnet 239 on the second bottom plate 235 cooperates with the first magnet 117 on the adsorbent 11 to keep the multiple adsorbents 11 in a vertical state and fix them in a specified position.

[0058] It should be noted that under the power of the driving rod 214, the first bottom plate 232, the second bottom plate 235 and the third bottom plate 237 all maintain their own state and move vertically upward. A certain height is left between the third bottom plate 237 and the conveying port 2210 to prevent the entering adsorption part 11 from blocking the door panel 2212.

[0059] Further, if Figures 13 to 19As shown, the cleaning assembly 24 includes a fountain 241 connected to the transmission pipe 213, a cover plate 243 connected to the fountain 241 through a fifth spring 242, a spiral track 244 connected to the cover plate 243, an externally threaded tube 245 sleeved on the first internally threaded rod 233, a second internally threaded tube 246 connected to the axis of the fountain 241 and meshing with the externally threaded tube 245 for transmission, and a guide rod 247 connected to the second internally threaded tube 246 and used to cooperate with the spiral track 244 to drive the cover plate 243 to move; The output assembly 25 includes a first gear ring 251 connected to the second internally threaded tube 246, a ratchet ring 252 connected to the bottom of the fountain 241 and meshing with the first gear ring 251, a rotating groove 253 provided on the fountain 241, a driving frame 254 connected in the rotating groove 253 and connected to the ratchet ring 252, a plurality of fixed rods 256 penetrating the driving frame 254 and connected to the driving frame 254 through second telescopic members 255, an output plate 257 connected to the fixed rods 256, a guide groove 258 provided on the annular groove 238, a drainage pipe 259 connected in the guide groove 258 and sequentially penetrating the first bottom plate 232 and the second bottom plate 235, a valve plate 2511 connected in the drainage pipe 259 and connected to the second gear 2510, and a second rack 2512 connected to the first bottom plate 232 and meshing with the second gear 2510.

[0060] In this embodiment, by providing a cleaning component 24 and an output component 25, the bottom adsorbent 11 is squeezed and rinsed when reused to completely renew its own water film, and has the most effective adsorption state when output, and the waste water for cleaning the adsorbent 11 is discharged separately to prevent it from contacting the adsorbent 11 again, thereby reducing the pressure of the overall adsorption work.

[0061] In detail, when the recycling assembly 23 moves to the nozzle position above the transmission pipe 213, the third bottom plate 237 is assembled with the plurality of output plates 257. As the recycling assembly 23 continues to move upward, the output plate 257, the fixing rod 256 and the second telescopic member 255 are contracted accordingly. At the same time, the first bottom plate 232 drives the externally threaded tube 245 sleeved on the first internally threaded rod 233 to contact the second internally threaded tube 246 connected to the axis position of the fountain 241 and meshing with the externally threaded tube 245. In the meshing state, the second internally threaded tube 246 rotates, and the second threaded tube drives the guide rod 247 to rotate. The guide rod 247 rotates to squeeze the water. The spiral track 244 is pressed, so that the cover plate 243 moves downward and drives the water in the fountain 241 to be sprayed on the lower adsorption member 11 through the air pressure. At the same time, the multiple adsorption members 11 are also driven by the third bottom plate 237 to contact and squeeze with the bottom of the fountain 241. The squeezing effect causes the first adsorption ring 111 and the second adsorption ring 112 to shrink together, and then cooperate with the first wiper ring 114 and the second wiper ring 115 to make the adsorption member 11 complete self-cleaning, and the waste water also flows into the guide groove 258 in the annular groove 238 together with the water in the upper fountain 241; then the first internal threaded pipe starts to drive the first bottom plate 23 2. The second bottom plate 235 and the third bottom plate 237 move downward, and the multiple adsorbents 11 are reset under the action of their own elastic sheets 113. The external threaded tube 245 drives the second internal threaded tube 246 to reverse, and the second internal threaded tube 246 drives the first gear ring 251 to rotate in the opposite direction, and then the first gear ring 251 drives the ratchet ring 252 to rotate, and the ratchet ring 252 drives the driving frame 254 in the rotating groove 253 to rotate, thereby driving the multiple output plates 257 to rotate. During the process, due to the action of the second telescopic member 255, the output plate 257 is always in contact with the third bottom plate 237. When the output plate 257 rotates, the multiple adsorbents 11 are The waste water is squeezed and output to the upper position. At the same time, the water on the third bottom plate 237 is also scraped off and concentrated into the guide groove 258. Since the third bottom plate 237 is spliced ​​with the second bottom plate 235, the second gear 2510 on the drain pipe 259 is meshed with the second rack 2512 on the first bottom plate 232 for transmission, so that the valve plate 2511 is opened, and the waste water is discharged downward from the drain pipe 259 and discharged through the bottom of the transmission pipe 213; when the first bottom plate 232 is reset to the bottom of the transmission pipe 213, the drain pipe 259 is first squeezed with the bottom of the transmission pipe 213, and the squeezing effect causes the second bottom plate 235 and the third bottom plate 237 to separate and reset.

[0062] It should be noted that the guide groove 258 has a certain inclination angle, so that the waste water automatically gathers to the position of the drain pipe 259, and the ends of the first wiper ring 114 and the second wiper ring 115 are set with a certain inclination angle, so that the scraped waste water will not flow to the first adsorption ring 111 and the second adsorption ring 112 again. When the guide rod 247 reverses, the squeezing of the spiral track 244 is cancelled, and the cover plate 243 is reset under the drive of the fifth spring 242; a one-way valve can also be set in the drain pipe 259 instead of the valve plate 2511; the ratchet ring 252 is not driven when the first gear ring 251 rotates forward.

[0063] Further, if Figure 2 and Figure 20 to Figure 21 As shown, the auxiliary mechanism 3 includes a guide component 31 arranged on the stirring component 21 and used to drive the circulating water at the bottom of the spray tower 100 to move for preliminary absorption of the exhaust gas, and a drying component 32 arranged in the intake pipe 200 and used to prevent the exhaust gas from staying in the intake pipe 200.

[0064] In this embodiment, by setting the guide component 31 and the drying component 32, the initial absorption of the exhaust gas and the maintenance of the intake pipe 200 are respectively completed under the premise of utilizing the power of the stirring component 21, which not only improves the adsorption effect but also ensures the cleanliness of the inside of the intake pipe 200.

[0065] In detail, driven by the power of the stirring component 21, the guiding component 31 lifts the bottom circulating water, so that the exhaust gas and the bottom circulating water are initially absorbed, and at the same time drives the drying component 32 to remove moisture from the inner wall of the intake pipe 200.

[0066] Further, if Figure 20 to Figure 21 As shown, the guide assembly 31 includes a long rod 311 connected to the driving rod 214, a vertical plate 312 connected to the long rod 311, a third reciprocating screw rod 313 connected to the driving rod 214, a third internally threaded tube 314 connected to the third reciprocating screw rod 313 and connected to the spray tower 100, a plurality of inclined plates 315 connected to the third internally threaded tube 314, and an arc-shaped plate 316 connected to the tail of the inclined plate 315.

[0067] It is worth mentioning here that by setting the guide component 31 in the auxiliary mechanism 3, the circulating water can continuously carry the exhaust gas to contact itself for initial absorption, and the rotation of the circulating water drives the input exhaust gas to rise in a spiral shape, changing the gas path, thereby promoting the full reaction and absorption of the volatile gas.

[0068] In detail, during the rotation of the driving rod 214, the third reciprocating screw rod 313 is driven to rotate, and then the third internal threaded tube 314 is driven to move up and down. Whenever it moves downward, the bottom ends of the multiple inclined plates 315 around it are inserted into the water surface, and under the rotation of the long rod 311 and the vertical plate 312, the circulating water flows into the inclined plate 315 and is discharged in the form of a waterspout through the arc plate 316, thereby entraining the exhaust gas to contact and be absorbed by the circulating water. In the process, the exhaust gas entering under the drive of the spiral effect of the water surface also shows a spiral upward trend.

[0069] Embodiment 2 like Figure 20 to Figure 21 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: Further, if Figure 20 to Figure 21 As shown, the drying component 32 includes a second gear ring 321 connected to the long rod 311, a fourth reciprocating screw 322 connected to the air intake pipe 200, a follower gear 323 connected to the fourth reciprocating screw 322 and meshing with the second gear ring 321, a cleaning ring 324 connected to the fourth reciprocating screw 322, and a drain outlet 325 opened on one side of the air intake pipe 200.

[0070] It is worth mentioning that by setting the drying component 32 to move back and forth on the inner wall of the intake pipe 200, the water mist remaining on the inner wall of the intake pipe 200 can be removed in time, thereby preventing the exhaust gas from being absorbed by the inner wall of the intake pipe 200 and always remaining on the inner wall of the intake pipe 200, preventing the solute from causing damage to the intake pipe 200.

[0071] In detail, the long rod 311 drives the second gear ring 321 to rotate, and the second gear ring 321 drives the fourth reciprocating screw 322 to rotate through the follower gear 323, thereby causing the cleaning ring 324 to reciprocate on the inner wall of the intake pipe 200, driving the water on the inner wall to be discharged downward through the drain port 325.

[0072] It should be noted that the cleaning ring 324 is connected to the air intake pipe 200 , and a water-absorbing sponge is provided on one side of the cleaning ring 324 . The water-absorbing sponge is squeezed at the end of the air intake pipe 200 to discharge its own moisture.

[0073] Embodiment 3 like Fig. 22 As shown, a preparation process for triethyl phosphate material is applied to a preparation system for triethyl phosphate material, comprising the following steps: Step 1, gas input process, when triethyl phosphate is produced by reaction, the waste gas is transported to the bottom of the spray tower 100 through the air inlet pipe 200, and then the gas moves upward under the guidance of air pressure. During the process, the guide component 31 lifts the circulating water and turns it in a spiral manner, thereby continuously entraining the waste gas to contact with the circulating water for preliminary absorption, and the input waste gas is driven to rise in a spiral shape through the rotation of the circulating water, changing the gas walking path, thereby promoting the full reaction and absorption of volatile gases; Step 2, gas absorption process, when the waste gas rises, the spray tower 100 sprays the circulating water by top spraying, and the water mist formed by the spraying forms a water film on the adsorption element 11, thereby increasing the reaction area, so that the waste gas is fully contacted with the water film for absorption; Step 3, recycling process, during the absorption process, the stirring component 21 in the moving component continuously stirs the upper and lower adsorbents 11, so that the upper adsorbent 11 falls to the lower position, and at the same time, the adsorbent 11 at the bottom of the lower layer is driven by the conveying component 22 and the recycling component 23 to return from the lower layer to the upper position, thereby completing the cycle; Step 4, cleaning process, during the recycling process, the adsorbent 11 is first adjusted in position under the action of the reuse component 23, and then the cleaning component 24 cleans it by squeezing and flushing, and then the output component 25 completes the separation output of the adsorbent 11 and the discharge of wastewater.
