Problems solved by technology

[0003] There have been a lot of research and practice at home and abroad on the reduction methods of paint waste. However, due to the characteristics of high water content, high viscosity, difficult transportation and difficult drying of paint waste, the existing reduction methods generally have low reduction rates. , high energy consumption per unit of drying, inability to process continuously, etc., making it difficult to promote on a large scale

Abstract

The invention discloses a drying method for a waste paint residue and belongs to the technical field of reduction treatment of hazardous wastes. The drying method adopts a waste paint residue drying system, which comprises a primary filtering device, a preheating device, a dosing device, a main drying machine and an exhaust gas treatment device, wherein the waste paint residue is fed to the primary filtering device for temporary storage and pretreatment; the preheating device is communicated with the primary filtering device, the dosing device and the main drying machine respectively; and themain drying machine is communicated with the exhaust gas treatment device through a vacuum pipeline. The drying method of the invention improves the reduction rate of the waste paint residue, reducesthe energy consumption for the unit drying of the waste paint residue, and achieves the reduction treatment of continuous drying of the waste paint residue.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to the technical field of hazardous waste reduction treatment, in particular to a method for drying paint waste. Background technique [0002] A large amount of paint waste generated on modern industrial painting lines belongs to HW12 dye and paint waste in the "National Hazardous Waste List". If it is not handled properly, it will seriously pollute the environment and be a great waste of resources. At present, landfill, incineration and recycling are commonly used in China to dispose of such waste, and waste production enterprises will pay high disposal fees for this every year. Considering the national environmental protection policy and the production cost of enterprises, the reduction, harmlessness and recycling of paint waste has become an inevitable choice for waste production enterprises, especially the reduction and treatment of paint waste needs to be urge...
