Description
Technical Field

Background
The existing polyvinyl alcohol production process mainly comprises a polymerization process, an alcoholysis process and a recovery process; the alcoholysis process realizes the molding of the resin and mainly comprises the steps of alcoholysis, crushing, squeezing, drying and the like. The alcoholysis reaction is completed in a 10-20 m alcoholysis machine with a belt conveyor; when the alcoholysis machine is stopped in special conditions or normally stopped, blocky polyvinyl alcohol materials with the width of about 1 meter, the thickness of 20cm and the lengths are present in the alcoholysis machine. The bulk polyvinyl alcohol cannot be transported to the subsequent process and therefore can only be taken out of the alcoholysis machine during the maintenance process. The polyvinyl alcohol blocky material is not treated by a subsequent process, and the material contains a large amount of alcohol decomposition liquid mainly containing methanol, so that the polyvinyl alcohol blocky material can only be treated as hazardous waste. In addition, the polyvinyl alcohol material has large tubers, the hardness of the material is continuously increased along with the time, the material can cause the change of a chemical structure at the temperature of more than 120 ℃, the material contains a large amount of volatile methanol, and the material can be dissolved and adhered when meeting water, so that the common crushing machine cannot realize safe crushing.
An invention patent application entitled "a new disposal apparatus for polyvinyl alcohol powder" is disclosed in CN106621550A, which teaches a process and apparatus capable of handling polyvinyl alcohol powder, but the process and apparatus are not capable of handling bulk polyvinyl alcohol resin.
A utility model patent entitled "new four-axis shredder" is disclosed in CN207839134U, which is capable of shredding resin products such as electronic waste, but it cannot directly handle large resin containing flammable and explosive volatile components.
The existing hazardous waste disposal mode of the polyvinyl alcohol alcoholysis waste material not only can generate high disposal cost, but also can have larger safety and environmental protection risks caused by volatile matters in the storage and transfer processes. The subsequent dangerous waste disposal mode of the polyvinyl alcohol alcoholysis waste is mostly incineration disposal, which does not realize the utilization of resources but causes the consumption of resources for the whole society.
