Problems solved by technology

In the existing pyrolysis recovery technology, the commonly used waste and old organic glass cracking reaction process is a batch reaction. The waste and old organic glass is directly put into the pyrolysis kettle heated by an open flame for manual cracking. Evenly, the pyrolysis kettle is prone to fouling and coking. When cleaning, it is necessary to open the lid of the pyroly

[0022] Example

[0023] The waste plexiglass pellets are transported from the screw feeder 1 to the silo 2. After the silo is filled with pellets, the gas in the silo 2 is replaced, vacuumed and filled with nitrogen, so that the pressure of the silo 2 is equal to the cracking kettle The pressure in 6 is the same, add liquid molten salt to cracking kettle 6, heat cracking kettle 6 to make the molten salt temperature reach about 460℃, then open the lower flap valve of silo 2 and vibrating feeder 4, waste organic glass The pellets are transported into the cracking kettle 6 through the new heat-proof radiation feeder 5. In the cracking kettle 6, the waste organic glass particles are quickly surrounded and gasified by the high-temperature molten salt. The gas is transported to the rectification system through the gas outlet pipe 8 for recovery; In the endothermic process, the temperature of the cracking tank 6 is controlled by controlling the feed amount of the vibrating feeder 4. Wh...

Abstract

The invention belongs to the technical field of novel cracking and recycling treatment of waste organic glass and particularly relates to a process and technological equipment for continuously cracking and recycling waste organic glass. A production process is characterized by comprising the following process steps of: treating waste organic glass; performing gas displacement; heating a heat transfer medium; and performing thermal cracking treatment. In the process, organic glass is heated and cracked by changing the heating mode of the organic glass with molten salt serving as a heat transfer medium. The molten salt does not undergo any chemical reaction with organic glass particles, and 'solid-in-liquid' is formed when liquid molten salt is contacted with solid organic glass, so that the contact surface is increased, uniform contact heating of the organic glass is facilitated and quick gasification is realized; and moreover, a continuous feeding and thermal cracking process method is adopted in the thermal cracking process, so that the production efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of cracking and recycling waste organic glass, and in particular relates to a continuous cracking and recycling process of waste organic glass and its process equipment. technical background [0002] Plexiglass composed of polymethyl methacrylate is widely used in various industries. However, using waste organic glass to crack and regenerate to obtain methyl methacrylate monomer to realize the recycling of organic glass is in line with the policy of circular economy and has good environmental, economic and social benefits, so it has developed rapidly in our country. In the existing pyrolysis recovery technology, the commonly used waste and old organic glass cracking reaction process is a batch reaction. The waste and old organic glass is directly put into the pyrolysis kettle heated by an open flame to be cracked manually. Evenly, the pyrolysis kettle is prone to fouling and coking. When cleaning, it is nec...
