Analysis of Wash Water Recycling Machine
The screen cleaning water recovery machine is an environmental protection device specifically designed to recover and purify waste screen cleaning water from industries such as printing and coating. By utilizing principles such as distillation, it purifies contaminated solvent waste into clean, reusable solvent, enabling resource recycling and reducing production costs.
Working Principle
The screen cleaning water recovery machine primarily operates on the principles of distillation separation and cooling condensation.
Heating distillation: Heat the used waste washing water to its boiling point to vaporize the organic solvents into gaseous form.
Cooling and condensation: The generated solvent vapor enters the cooling system (typically air-cooled or water-cooled) and re-liquifies into a liquid state.
Collection and reuse: The purified liquid solvent flows into a collection container and can be reused for cleaning tasks.
Residue Handling: Solid impurities such as ink and resin, along with non-volatile substances from the original waste liquid, remain in the distillation釜 as residue and are removed during cleaning.
Main Features and Advantages
High Recovery Rate: Most equipment achieves a recovery rate of approximately 95%.
Explosion-proof design: Since washing water often consists of flammable and explosive organic solvents, certified recycling machines are designed with a fully explosion-proof structure and have passed relevant explosion-proof certifications to ensure safe operation.
Multiple safety protections: The device is typically equipped with multiple safety features, including automatic shut-off at set temperature or time, over-temperature/over-pressure protection, and power failure protection.
Corrosion-resistant material: Components in contact with solvents (such as recovery tanks) are mostly made of SUS304 stainless steel, which offers excellent corrosion resistance.
Easy to operate: The equipment features a highly automated workflow, allowing regular employees to start operating after simple training.
