S1, the water source is replenished. The liquid level of the water tank 11 is set by the PLC controller 10. When the liquid level gauge 12 detects that the liquid level of the water tank 11 is lower than the set liquid level, the PLC controller 10 opens the first angle valve 13 to replenish water to the water tank 11. Among them, the filter 14 is used to filter the water input into the water tank 11.

Enter the water tank 11 to heat the water, and close the second angle valve 22 after a delay of 10 seconds after reaching the set temperature;

S3, the front chamber adds water flow calculation, the inlet moisture meter 8 detects the moisture data of the leaf silk at the inlet 71, sends the detected data to the PLC controller 10, and the PLC controller 10 is also used to obtain the flow data of the leaf silk at the inlet 71, The PLC controller 10 calculates the flow rate and moisture of the silk when the silk reaches the inlet 71, the middle and the outlet 72 of the super moisturizing drum 7 according to the moisture data and flow data of the silk, and obtains the inlet 71 of the super moisturizing cylinder 7 according to the calculation. The flow rate of adding water to the leaf silk;

It should be noted that the PLC controller 10 obtains the flow data of the leaf silk at the inlet 71 and obtains the flow data of the leaf silk at the entrance 71 by connecting with the electronic scale set on the super reconditioning machine.

S4, water is added to the front chamber, and according to the water flow rate obtained in step S3, the PLC controller 10 opens the third angle valve 35, and the PLC controller 10 controls the first variable frequency gear pump 31 to deliver the water inside the water tank 11 to the first dual medium nozzle 34 , after the steam and water in the steam pipeline 5 are mixed and atomized, water is added to the blade silk at the inlet 71 of the super moisture conditioning drum 7, and the first variable frequency gear pump 31 is controlled by collecting flow data through the first electromagnetic flowmeter 33;

S5, the back chamber adds water flow calculation, the outlet moisture meter 9 detects the moisture data of the leaf silk at the outlet 72, sends the detected data to the PLC controller 10, and the PLC controller 10 calculates the outlet of the super moisturizing drum 7 according to the moisture data of the leaf silk 72 leaf silk adding water flow;

To prevent the frequency of the first variable frequency gear pump 31 and the second variable frequency gear pump 41 from jumping frequently, the "dead zone" parameter is set greater than "0.2" ;

The calculation process of adding water flow is as follows:

According to the same weight of the incoming and outgoing leaf silk (dry material) of the super moisturizing drum 7, the following formula is obtained:

①Flow rate of leaf silk (dry material) = flow rate of leaf silk at the entrance * (1-water content of leaf silk at the entrance);

②Flow rate of leaf silk (dry material) + theoretical amount of water added = flow rate of leaf silk at outlet = leaf silk (dry material)/(1-water content of leaf silk at outlet);

Find:

③Theoretical amount of water added at the inlet = flow rate of the leaf silk at the entrance * (1-the moisture of the leaf silk at the entrance) [1/(1-the moisture of the leaf silk at the exit)-1];

It should be noted that, in the above ② and ③, the moisture content of the leaf silk at the outlet is the moisture content of the leaf silk at the exit set in the process requirements.

In order to reduce the phenomenon of wet mass or "surface wetness" of materials caused by adding water to the rear chamber, the actual amount of water added in the front chamber = the theoretical amount of water added * K, where the upper and lower limits of the K value are set to 0.8-0.9, which is used to ensure large flow of water in the front chamber. Compensation for water addition in the chamber, the output y(t) is the actual water addition flow;

By stacking the delay time, the flow rate and moisture of the leaf silk when the leaf silk reaches the inlet 71, the middle and the outlet 72 of the super moisturizing drum 7 are calculated respectively;

The actuators for adding water in the back chamber are the same as those for adding water in the front chamber. They are all variable frequency gear pumps. The input R(t) is the moisture content of the leaf silk at the outlet set in the process requirements, and the output Y(t) is the moisture at the outlet 72 of the super moisturizing drum 7. detection value.

The whole process of adding water is mainly to add water to the front chamber, supplemented by adding water to the rear chamber, which is used to supplement the front chamber after adding water.

The specific working principle is that by obtaining the moisture data of the leaf silk at the inlet 71 and the outlet 72 of the super moisturizing drum 7, and also obtaining the flow data of the leaf silk at the inlet 71 of the super moisturizing drum 7, it is calculated that the leaf silk reaches the super moisturizing drum 7. At the inlet 71, the middle and the outlet 72, the flow rate of the leaf silk and the moisture content of the leaf silk are calculated, and the flow rate of adding water to the leaf silk at the inlet 71 of the super moisturizing drum 7 is calculated. At 72:00, according to the moisture data of the leaf silk at the outlet 72 combined with the process requirements parameters, the flow rate of the leaf silk added water is calculated, and the water is replenished at the outlet 72, which solves the problem of the existing super moisture regainer. Large hysteresis, the moisture at the outlet 72 fluctuates greatly and is unstable, which seriously affects the control of the moisture at the outlet of the dryer.

s3, calculating the water flow rate of the front chamber, detecting the moisture data of the cut tobacco at the inlet by the inlet moisture meter, sending the detected data to the PLC, obtaining the flow data of the cut tobacco at the inlet by the PLC, calculating the cut tobacco flow rate and the cut tobacco moisture when the cut tobacco reaches the inlet, the middle part and the outlet of the super dampening roller by the PLC according to the moisture data and the flow data of the cut tobacco, and obtaining the water flow rate of the cut tobacco at the inlet of the super dampening roller according to the calculation;

s4, adding water into the front chamber, opening a third angle valve by the PLC according to the water adding flow obtained in the step S3, controlling a first variable frequency gear pump to convey water in the water tank to a first dual-medium nozzle by the PLC, mixing and atomizing steam and water in a steam pipeline, adding water into cut tobacco at the inlet of the super dampening roller, and simultaneously collecting flow data through a first electromagnetic flowmeter to control the first variable frequency gear pump;

s5, calculating the water flow in the back room, detecting the water data of the cut tobacco at the outlet by the outlet moisture meter, sending the detected data to the PLC, and calculating the water flow of the cut tobacco at the outlet of the super dampening roller by the PLC according to the water data of the cut tobacco;

and S6, adding water into the rear chamber, opening a fourth angle valve by the PLC according to the water adding flow obtained in the step S5, controlling a second variable frequency gear pump to convey water in the water tank to a second dual-medium nozzle by the PLC, mixing and atomizing steam and water in the steam pipeline, adding water into the cut tobacco at the inlet of the super dampening roller, and simultaneously collecting flow data through a second electromagnetic flowmeter to control the second variable frequency gear pump.
