Examples
example 1
[0016] The conditions of Example 1 are: power supply peak voltage 12kV, power supply discharge frequency 7.5kHz; gas flow rate 200ml / min, gas temperature: room temperature.
[0017] Example 1 processing results are shown in Table 1:
[0018] Table 1
[0019]
[0020] It can be seen from Table 1 that the removal efficiency of sulfuryl fluoride decreases with the increase of the inlet concentration. When the inlet concentration of sulfuryl fluoride is lower than 5000ppm, this method can completely remove sulfuryl fluoride gas.
example 2
[0021] Example 2, change the input voltage of the power supply, investigate the impact of injected energy density on the removal effect of sulfuryl fluoride, other conditions are as in Example 1, and the results are shown in Table 2:
[0022] Table 2
[0023] Import concentration (ppm)
[0024] It can be seen from Table 2 that the removal efficiency of sulfuryl fluoride increases with the increase of injected energy density. When the energy density is 1300J / L, the removal efficiency can reach 100%.
example 3
[0025] Example 3, change the discharge frequency, investigate the influence of the power supply frequency on the sulfuryl fluoride removal effect, other conditions are as in Example 1, and the results are as shown in Table 3:
[0026] table 3
[0027] Import concentration (ppm)
[0028] It can be seen from Table 3 that the removal efficiency of sulfuryl fluoride has an optimal value for the discharge frequency. When the discharge frequency is 8kHz, the removal efficiency can reach 100%.
