Abstract

The invention discloses an organic glass waste degradation process with high thermal efficiency, belongs to the technical field of organic glass production, and aims to solve the problems that the heat utilization rate is low and energy conservation and environmental protection are not enough when existing organic glass waste is recovered and degraded. The method comprises the following steps: (1) descaling organic glass waste, putting the organic glass waste into a storage bin, and conveying the organic glass waste into a cracking furnace through a screw conveyor; (2) uniformly distributing the organic glass waste through a material distributor; (3) annularly distributing a heating pipe in a cracking furnace, adopting heat conduction oil and molten salt as a heating medium, and heating the heating medium to 400 DEG C; (4) circulating the heating medium in the heating pipe to heat the organic glass waste for 8-10 h, and stirring through a stirrer during heating; (5) vaporizing methyl methacrylate in the organic glass waste by heating, discharging the vaporized methyl methacrylate from the cracking furnace, and condensing the vaporized methyl methacrylate through a condenser to obtain a methyl methacrylate liquid; and (6) discharging the cracked waste residue through a residue discharging device, and then collecting the waste residue. The process is suitable for organic glass waste degradation.

Description

technical field [0001] The invention belongs to the technical field of organic glass production, and in particular relates to a process for degrading organic glass waste with high thermal efficiency. Background technique [0002] Plexiglass has been widely used in life. The raw material for producing plexiglass is usually plexiglass oil. There are usually two ways to obtain plexiglass oil, one is to melt oil, and the other is to melt waste plexiglass. The method of melting waste plexiglass to obtain plexiglass oil can reduce the consumption of petroleum resources and realize the recycling of waste plexiglass, which has become an important method for the manufacture of plexiglass oil. [0003] Recycling and utilization of waste plexiglass can not only reduce oil consumption, but also realize the reuse of waste plexiglass, which is in line with the national waste resource recycling policy. The main way to recycle waste plexiglass is to use heating to melt waste plexiglass t...
