Abstract

The invention relates to the field of organic glass recycling, and relates to organic glass recycling process equipment. The organic glass recycling process equipment comprises a crushing device, a cracking device, a coarse product recycling device, a coarse product purifying device and a product recycling device which are sequentially arranged; the coarse product recycling device comprises a first-stage condenser, a second-stage condenser and a deep condenser; the coarse product purifying device comprises a cleaning part, a settling part and a rectifying assembly, the rectifying assembly comprises a heating kettle, a rectifying tower, a first condenser, a second condenser and a finished product tank which are sequentially connected with the settling part, and a head fraction tank and a tail fraction tank are further connected to the second condenser by being parallel to the finished product tank. The organic glass recycling process equipment conducts efficient crushing and thorough cracking on waste organic glass, and the obtained recycled materials are high in purity and meet subsequent processing requirements.

Description

technical field [0001] The invention relates to the field of plexiglass recycling and utilization, and relates to a plexiglass recycling process equipment. Background technique [0002] The organic glass whose main component is polymethyl methacrylate is widely used in various industries. The use of waste plexiglass cracking and regeneration to obtain methyl methacrylate monomer to realize the recycling of plexiglass, in line with the policy of circular economy, has good environmental, economic and social benefits, so it has developed rapidly in my country. In the existing cracking recovery technology, the commonly used waste plexiglass cracking reaction process is a batch reaction. The waste plexiglass is directly put into a cracking kettle heated by an open flame and cracked. The materials are accumulated in the kettle and contact with the cracking kettle wall. Evenly, the cracking kettle is easy to scale and coke. When cleaning, it is necessary to open the lid of the cra...
