Embodiment 1
[0036] (1) In the initial step, after the normal production of the monomer synthesis unit, the pulp residue is manually discharged twice, and the automatic program automatically records the discharge time interval and the solid content of the pulp residue discharged from the sending tank;
[0037] (2) Waiting step, after the slurry conveying is completed, the solid content automatic discharge slurry program is put into use, and the target value of the solid content of the slurry discharge is 50%, and the initial discharge interval is 5 hours. Calculate the time interval for discharging pulp and slag this time, and when the timing interval is reached, start the pulp and slag filling step;
[0038] (3) Filling steps: detect that V2, V3, V4, and V5 are in the closed state; open V4, wait for 60s, and start the time interval timing for the next discharge of pulp and slag at the same time; open V2, and the material in the evaporation system is transported to the delivery system. Whe...
Embodiment 2
[0046] Other steps are consistent with embodiment 1, the difference is that the solid content target setting value is 45%. Table 2 is the 45% automatic discharge slurry slag statistics table of embodiment 2 solid content target setting value:

Embodiment 3
[0050] The other steps are the same as in Example 1, except that the solid content target setting value is 55%, and the sending pressure value set in the automatic program sending step is optimized to 4.2 bar. Table 3 is the 55% automatic discharge slurry slag statistics table for embodiment 3 solid content target setting value:
