将含二苯砜的聚醚醚酮物料气流输送到反应釜R中，并及时从C1储罐向R中泵

The polyether ether ketone material containing diphenyl sulfone is transported to the reactor R in a gas flow, and acetone is pumped from the C1 storage tank to R in time, and the R stirring blade is started in time. Open the R steam inlet valve for heating, and the temperature is controlled at 40°C. Afterwards, continue to cook until the diphenyl sulfone in the solution in the kettle reaches a higher mass fraction, release all the solution in the kettle at one time, and then re-pump it into fresh acetone for extraction. After repeated treatment for many times, until the mass fraction of diphenyl sulfone in the solution meets the production requirements. <br>Due to the large number of leaching in the recycling process, more than 8 acetone mixed liquid storage tanks must be arranged in the process, and the energy consumption is relatively high. The cooking process is close to the cyclic process, but due to mass transfer factors, the efficiency of this process is lower than that of the cyclic process. The extraction process relies on material circulation in the system, which saves time, is simple in process and uses less acetone, but its disadvantage is high energy consumption. Fat extraction and improved fat extraction technology are relatively better, but the structure of the extraction kettle is special, and problems such as pipeline blockage often occur. <br>The water extraction process is also often referred to as water washing. One process is to boil with water under slow intermittent stirring, boil it to a certain extent to release the water, and then add fresh water until the water-soluble substances such as fluoride salt are washed out; the other process is to consider that the mixing will cause the material to pulverize. The mass transfer process is strengthened in the form of circulating water flow, that is, a water outlet is added at the bottom of the washing tank, and a filter device is added at the same time. Outflow, cyclically. <br>After leaching the diphenyl sulfone with acetone and washing the fluoride salt with water, the polyether ether ketone product is centrifuged to remove most of the water contained therein, and dried in a double-cone dryer vacuum to obtain a pure material. This form of drying, due to the high temperature in the system and rich in water vapor, when the temperature is lowered and the material is discharged, the water returns to the surface of the material, and the water increases during the test, and it takes a long time to meet the drying requirements.

The air flow of polyether ketone containing diphenyls is delivered to the reactor R, and acetone is pumped from the C1 tank to R in time to start the R mixing oar in time. Open the R steam inlet valve for heating and temperature control at 40 degrees C. After the time has been cooked, until the solution in the kettle of diphenyl to achieve a higher quality score, a one-time release of all the solution in the kettle, and then, re-pumped into the fresh acetone immersion. After repeated treatment, until the quality fraction of diphenyl in the solution meets the production requirements.<br>Due to the number of leaching times, more than 8 acetone mixture tanks should be arranged in the process, and the relative energy consumption is high. The cooking process is close to the recycling process, but due to mass transfer factors, the efficiency of this process is lower than that of the cycle process. The extraction process relies on the material circulation in the system, saving time, the process is simple, the amount of acetone is small, but the disadvantage is high energy consumption. Fat extraction and improvement of fat extraction process is relatively good, but the immersion kettle structure is special, but also often appear pipeline blockage and other problems.<br>The water immersion process is also often referred to as washing. A process is to stir at a slow interval under the water boiling, boiled to a certain extent to release the water, and then add fresh water, until the fluorine salt and other water-soluble substances washed; Another process is to consider stirring will make the material powdered, the use of circulating water flow form to strengthen the mass transfer process, that is, in the bottom of the washing kettle to add a water outlet, while adding a filtration device, the internal upper end of the reactor with a water distribution pipe, water through the circulation pump from the upper part of the kettle into, the lower outflow, cycle.<br>After acetone leaching diphenyls, water washed out fluorine salts, etc. , polyether ketone products by centrifugal separation to remove most of the moisture immersed in it, by the double cone dryer vacuum drying, and finally get pure material. This form of drying, due to the high temperature in the system, rich in water vapor, cooling discharge, moisture back to the surface of the material, detection of water increased larger, to meet the drying requirements take a long time.

The PEEK material containing diphenylsulfone was transported to reactor r by air flow, and acetone was pumped into reactor r from C1 storage tank in time, and R agitator was started in time. Open r steam inlet valve for heating, and control the temperature at 40 ℃. After that, it was boiled until the diphenylsulfone in the kettle solution reached a high mass fraction, and then all the kettle solutions were discharged at one time, and then fresh acetone was pumped in again for leaching. After repeated treatment for several times, the content of diphenylsulfone in the solution reached the production requirements.<br>Due to the large number of leaching times, more than 8 acetone mixed liquid tanks should be arranged in the circulation process, and the relative energy consumption is high. The cooking process is close to the circulation process, but its efficiency is lower than the circulation process due to mass transfer. The extraction process depends on the material circulation in the system, which saves time, and the process is simple with less acetone consumption, but the disadvantage is high energy consumption. Fat extraction and improved fat extraction process are relatively better, but the structure of the extraction kettle is special, and the pipeline is often blocked.<br>The water leaching process is also called water washing. One process is to boil with water under slow intermittent stirring, to a certain extent, release the water, and then add fresh water until the water-soluble substances such as fluoride salt are washed; Another process is to consider that stirring will pulverize the materials, and adopt the form of circulating water flow to strengthen the mass transfer process, that is, to add an outlet at the bottom of the washing kettle and a filter device at the same time. The upper end of the reactor is equipped with an inlet distribution pipe, and the water is pumped from the upper part of the washing kettle through the circulating pump, and then flows out from the lower part for circulation.<br>After acetone leaching diphenylsulfone and water washing out fluoride salt, the product of PEEK is centrifuged to remove most of the water, and then vacuum dried in a double cone dryer to obtain pure material. In this form of drying, due to the high temperature in the system and rich in water vapor, the moisture will return to the surface of the material when the material is cooled and discharged, and the moisture will increase greatly during the detection, so it will take a long time to reach the drying requirements.<br>
