After the numerical value of the settlement amount of the data in the table I is obtained, the industrial personal computer 401 and the PLC402 automatically adjust the liquid level height of the brine tank and the spraying pressure according to the settlement amount set by a user so as to achieve the target settlement amount. After the parameters of the table are obtained, the liquid level height of the brine tank and the spraying pressure are automatically adjusted by the industrial personal computer 401 according to the settlement amount set by a user so as to achieve the target settlement amount. The table values are fixed and do not need to be adjusted when there is no change in hardware devices such as aerosol valve 11.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of practicing the invention, and that various changes in form and detail may be made therein without departing from the spirit and scope of the invention in practice.
