The control board 12 controls the second check valve 913 to keep the state for five minutes, and then controls the second check valve 913 to work again, so that the volume of the carbon powder that can flow in the nozzle 91 is restored to 1/3 that occupies the total volume, and at this time, the relationship between the real-time flow rate Qs and the standard flow rate Qb is determined again.
When the real-time flow rate Qs is less than the standard flow rate Qb and the real-time humidity Rs is greater than the maximum humidity Rz, the control board 12 controls the second check valve 913 to operate, so that the volume of the carbon powder circulating in the nozzle 91 is changed from 1/3 occupying the total volume to 1/5 occupying the total volume, until the real-time humidity Rs is less than or equal to the maximum humidity Rz, the control board 12 controls the second check valve 913 to operate, and further the volume of the carbon powder circulating in the nozzle 91 is restored to 1/3 occupying the total volume. In some embodiments of the present invention, when the real-time flow rate Qs is less than the standard flow rate Qb and the real-time humidity Rs is greater than the maximum humidity Rz, the control board 12 controls the first stop valve 912 to operate, opens the first stop valve 912 after the spray head 91 is turned off for three minutes, and then controls the second stop valve 913 to operate by the control board 12.
When the real-time flow rate Qs is greater than the standard flow rate Qb and the real-time humidity Rs is less than the maximum humidity Rz, the control board 12 controls the first check valve 912 to work, the spray head 91 is cut off, and meanwhile the alarm device gives an alarm to determine that the device is in fault.
When the real-time flow rate Qs is greater than the standard flow rate Qb and the real-time humidity Rs is greater than the maximum humidity Rz, the control board 12 controls the second check valve 913 to operate, so that the volume of the carbon powder circulating in the nozzle 91 is changed from 1/3 occupying the total volume to 1/5 occupying the total volume, until the real-time humidity Rs is less than or equal to the maximum humidity Rz, the control board 12 controls the second check valve 913 to operate, and further the volume of the carbon powder circulating in the nozzle 91 is restored to 1/3 occupying the total volume. In some embodiments of the present invention, when the real-time flow rate Qs is greater than the standard flow rate Qb and the real-time humidity Rs is greater than the maximum humidity Rz, the control board 12 controls the first stop valve 912 to operate, opens the first stop valve 912 after the spray head 91 is turned off for three minutes, and then controls the second stop valve 913 to operate at this time by the control board 12.
