AI Technical Summary
The solvent discharged from the hydrogen peroxide extraction tower carries impurities such as catalyst powder, reaction byproducts, and solid particles. Direct reuse of these impurities would lead to a decline in the performance of the working fluid and increased equipment wear. Existing solvent recovery devices are prone to clogging and are cumbersome to operate, affecting continuous production.
A solvent recovery device with a buoyancy airbag and a lifting plate was designed. The buoyancy airbag drives the suction head to rise and fall with the liquid level. Combined with movable scrapers and push plates to clean the filter screen, the device achieves automated filtration and purification of solvent, avoiding the intake of impurities and clogging.
It improves the quality and reuse rate of solvent recovery, reduces production costs, realizes the automation and efficiency of solvent recovery, and reduces equipment maintenance time.
