Problems solved by technology
The disadvantages of using this method are: 1. The insulation of the boiler is poor, and the heating process consumes a lot of energy
2. The acrylic plates in the boiler are heated unevenly, the temperature of the peripheral acrylic plates is too high, but the central acrylic plate has not reached the cracking and evaporation temperature, which affects the cracking efficiency and recovery quality
3. The heated slag needs to be cleaned by opening the lid of the boiler. Because MMA gas is irritating, it will affect the health of operators

The invention discloses a heating system for MMA monomer production. The heating system comprises a first heating tube, a second heating tube and a second heating tube which are connected in sequence,wherein screw rods are correspondingly arranged in the first heating tube, the second heating tube and the third heating tube, and the first heating tube, the second heating tube and the third heating tube are correspondingly provided with heating devices; and a feeding port is formed in the front end of the first heating tube, a first air outlet tube is arranged on the first heating tube, secondair outlet tubes are arranged at different positions on the second heating tube, and third air outlet tubes are arranged at different positions on the third heating tube. According to the heating system, the system is closed in the whole heating process, so that no pollution gas is released, and the effects of being safe and environment-friendly are achieved; and acrylics are fully stirred and dispersed in the heating process so that the cracking efficiency can be improved, the conversion speed can be increased, and the discharge amount of residues can be reduced.
Description
technical field [0001] The invention relates to the field of MMA monomer production, in particular to a heating system for MMA monomer production. Background technique [0002] Methyl methacrylate is an organic compound, also known as MMA, referred to as methyl methyl ester. It is an important chemical raw material and a monomer for the production of transparent plastic polymethyl methacrylate (plexiglass, PMMA). Acrylic plates used to produce bathtubs will crack MMA after being heated to a certain temperature. Recycling, heating and cracking waste acrylic plates, and recovering and storing the main cracking product MMA is an effective method for recycling acrylic plates. [0003] The existing acrylic plate heating mainly uses a boiler, and the acrylic plate is placed in the boiler for heating, and the cracked gas is collected on the top of the boiler. The disadvantages of using this method are: 1. The insulation of the boiler is poor, and the heating process consumes a lo...
