The working process is as follows: (1) firstly, closing each valve, opening a feed valve 21 and a liquid inlet valve 112, and respectively putting sulfur hexafluoride adsorbent to be cleaned and liquid cleaning agent into the reaction cavity I11; then, the feed valve 21 and the liquid inlet valve 112 are closed (2), the electromagnetic oscillator is opened to drive the ultrasonic transducer array 33 located in the reaction chamber i 11 to emit ultrasonic waves to the inside of the reaction chamber i 11, so as to clean the sulfur hexafluoride adsorbent; (3) after the sulfur hexafluoride adsorbent is fully cleaned, closing the electromagnetic oscillator, opening the communication valve 113, discharging the waste liquid into the reaction chamber II, closing the communication valve 113, and then opening the electromagnetic oscillator to drive the ultrasonic transducer array 33 positioned in the reaction chamber II to emit ultrasonic waves into the reaction chamber II, so that the waste liquid is subjected to harmless treatment; (4) after the waste liquid is sufficiently harmlessly treated, the electromagnetic oscillator is closed, the liquid discharge valve 121 is opened, and the harmlessly treated waste liquid is discharged from the liquid discharge port.
The specific principle of cleaning the sulfur hexafluoride adsorbent in the inner cavity of the reaction cavity I11 is as follows: (1) the ultrasonic transducer array 3 generates ultrasonic waves to generate an ultrasonic cavitation effect. The ultrasonic cavitation vibration frequency is in the order of ten thousand times per second, in the water body of the reactor, the ultrasonic wave with certain intensity can make the micro bubble (cavitation nucleus) in the liquid violently oscillate under the action of the sound field, when the sound pressure reaches a certain value, the bubble rapidly expands, contracts and then is suddenly closed, when the bubble is closed, the shock wave is generated, a local high-temperature high-pressure area is formed, namely a hot spot is formed, the temperature can reach 4000K, and meanwhile, the pulse pressure of about 100MPa is generated. FromAnd strong mechanical stirring effect which can break through the limitation of laminar boundary layer can be formed between the interfaces, so that the vibration energy of adsorbate molecules is increased, and the generated internal and external pressure gradient force of the adsorbent can easily remove impurity adsorbates adsorbed in the molecular sieve, so that the impurity adsorbates are separated from the adsorbent, and the adsorbent can recover better adsorption performance. (2) The high-temperature and high-pressure environment generated by the ultrasonic cavitation effect and the microjet with the speed of about 110m/S and strong impact force can ensure that the fluorine-sulfur compound S2F10Is heated to decompose part of decomposition products, and the cleaning agent-water should avoid high concentration of calcium and magnesium ions to avoid MgF2With CaF2The large amount of precipitation; on the other hand, the vibration of medium elements caused by the ultrasonic cavitation effect accelerates the displacement speed and the molecular collision speed, and simultaneously applies larger impact force to mass points, so that chemical bond breakage occurs in the cavitation nucleus for sulfur-based functional group chemical bonds of sulfide in impurities.
Wherein, the chemical reaction is as follows:
SF4+H2O→SOF2+2HF
SOF2+H2O→SO2+2HF
SO2+H2O→H2SO3
the specific principle of carrying out innocent treatment on the waste liquid for cleaning the sulfur hexafluoride adsorbent in the inner cavity of the reaction cavity II 12 is as follows: (1) the ultrasonic transducer array generates ultrasonic waves to generate an ultrasonic cavitation effect. The ultrasonic cavitation effect pyrolysis and the free radical reaction are carried out in the treatment process. The energy generated by collapse of the cavitation bubbles causes the water vapor to undergo fission and chain reaction at high temperature and high pressure, and a hydroxyl radical (. OH) strong oxidant with high chemical activity is formed in the water. In addition, air (N) dissolved in the solution2And O2) Free radical cleavage reaction to produce.N2And O2A free radical. Wherein, the free radical containsThe paired electrons are extremely unstable, and thus the superoxide radical reacts with hydrogen ions in the solution to generate hydrogen peroxide, consuming hydrogen ions (H) in the water+) The process is a chain reaction, and the generated oxygen can generate free radicals again due to the ultrasonic cavitation effect and react again; and because of the strong oxidizing property of the hydrogen peroxide, low-valent sulfur ions in the solution can be oxidized into high-valent sulfur ions, thereby forming hydroxyl ions (OH)-) And carrying out acid-base neutralization reaction with hydrogen ions in the solution, and gradually increasing the pH value of the aqueous solution through the two steps. (2) On the other hand, since the free radical, particularly the hydroxyl radical (. OH), has strong oxidizing property, it will take electrons from the neighboring molecules and stabilize itself, and the low-valent impurity ions will lose electrons and initiate redox reaction to generate high-valent sulfide ions, so that SF will be oxidized and reduced2、SF4The low-valence fluoride does not exist any more, so that low-valence impurity ions in the aqueous solution react, and some functional groups and organic molecules are broken, such as sulfur-oxygen functional groups, carbon tetrafluoride and the like, to promote the decomposition of toxic substances. (3) During the ultrasonic degradation process, a complex series of intermediate compounds, such as CF, are produced4CF is generated in the degradation process3、CF2CF, etc., but under the condition of proper degradation condition and enough long reaction time, the final products of ultrasonic degradation are C and F-Toxic fluorides, being thermodynamically stable simple or mineralized substances, can also be degraded.
Wherein, the chemical reaction is as follows:
2·O2+2H+→H2O2+O2↑
2H2O2+S2+→2·OH+2OH-+S4+
H++OH-→H2O
in actual operation, the device can be used for cleaning the sulfur hexafluoride adsorbent for multiple times so as to reach the recovery standard.
