Comprehensive utilization device and method for waste in PVB resin production process |
| abstract |
The invention discloses a comprehensive utilization device and a method for wastes in a PVB resin production process, wherein the process route is as follows: after the pH of the waste is regulated step by step through a waste collection tank, a feeding tank and an alkali liquor tank, the waste is heated through a feeding preheater and then conveyed to a butyraldehyde removal tower for treatment; gas evaporated from the butyraldehyde removal tower is treated by a condenser and a phase separator to obtain oil phase butyraldehyde and water phase waste, and the water phase waste returns to the butyraldehyde removal tower for continuous treatment; and (3) exchanging heat of the kettle liquid of the butyraldehyde removal tower through a feeding preheater, and then treating the kettle liquid in a concentration device, an evaporation device and a crystallization device to obtain sodium chloride solid. The method realizes the complete reuse of water resources and the complete regeneration of industrial wastes, and meets the requirements of green development and high-quality development. |
