Abstract

The invention discloses a comprehensive treatment device for aging resin, which comprises: an extraction kettle 1, a phase separator 1, a phase separator 2, and a distillation kettle 4; the extraction kettle 1 and the phase separator 1 are connected through pipelines , and a material pump one 6 is arranged in the middle; the phase separator one 2 and the phase separator two 3 are connected through pipelines, and a buffer tank 7 is arranged in the middle, and a material pump two 8 is arranged between the buffer tank 7 and the phase separator two 3 ; The top of the still 4 is connected with the still condenser 5, and the still condenser 5 is equipped with a condensate receiver 10; the bottom of the still 4 is connected with the centrifuge 9 through a pipeline. The device of the invention can realize continuous production, increase output and simplify operation. At the same time, through the design of the structure of the phase separator and the height of the outlet pipe, the separation effect of each component is improved and the recovery efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of processing by-products in the production process of epoxy resin, in particular to a comprehensive processing device for aging resin and a processing method thereof. Background technique [0002] Aging resin is a by-product of epoxy resin production due to oxidation, chemical action, etc., caused by aging and yellowing of epoxy resin during the production process of epoxy resin. For a long time, aging resin has been regarded as solid waste, which is disposed of by incineration, landfill and other methods. In recent years, with the increasing requirements of environmental protection, the cost of using the original method of processing is also getting higher and higher. The processing of aging resin has attracted the attention of various manufacturers, and various recycling technologies for aging resin have emerged. [0003] The aging resin contains 15-25% of recyclable epoxy resin, 10-15% of toluene and 40...
