Customized solvent recovery for the large-scale spraying industry (for mixed solvent recovery)
Customer background: An automotive parts spraying factory using various paints and solvents.
Requirements and pain points: Varying types of solvents: The sources of waste solvents are diverse, with unstable components, and the mixing ratio for each recovery may be different.
Pursuit of economic benefits: The requirements for the purity of the recovery are not as high as in the electronics industry, but it pays great attention to energy consumption and recovery speed, and requires a short investment return period. Simple operation: The equipment needs to be robust and durable, easy to operate and maintain, and workers can get started with simple training.
Floor space: The workshop space is limited, and the equipment needs to have a compact structure.
Customized solution: Batch distillation + Programmed temperature control: Use a single-tank batch recovery machine, through preset different temperature curve programs to adapt to different mixed solvent formulas, one machine for multiple uses, high flexibility. Energy-saving design: Equipped with a heat medium oil circulation system (heat transfer oil furnace) for indirect heating, uniform heating, avoiding local overheating and coking; at the same time, adopt efficient energy-saving insulation layers to reduce heat loss. Intelligent operation: PLC system has built-in multiple common solvent recovery recipes (Recipes), the operator only needs to select the recipe and start it with one click, the system automatically completes the entire recovery process. Compact design: Adopt vertical or modular design, reducing equipment floor space. Equipped with universal wheels, can be flexibly moved within the workshop. Basic explosion-proof: According to the customer's workshop grade, provide explosion-proof configurations that comply with the Chinese Ex d IIB T4 Gb standard, meeting safety regulations requirements. Results: Achieved unified recovery and treatment of various waste diluents, the recovered solvents can be used as low-requirement cleaning agents or diluents for reuse. Energy consumption is reduced by approximately 20% compared to standard models, the investment return period is controlled within 12-18 months. The operation interface is simple and intuitive, greatly reducing the reliance on professional operators.
