[0002] Low naphthalene aromatic solvents are widely used in various low naphthalene content coatings, silver pastes, pharmaceuticals and other industries. They can also be used in advanced baking varnish solvents, insecticide emulsions and rubber resin solvents. As environmental protection requirements become more and more stringent, the naphthalene content in naphthalene-free high-boiling point aromatic solvents is also required to be lower and lower. Therefore, it is necessary to use crystallization equipment to process the materials to reduce the naphthalene content in the materials.

[0003] However, the existing equipment does not have a crystallization tower with an over-temperature alarm function. When the temperature inside the tower exceeds the standard temperature, it will affect the crystallization quality of the equipment, so that relevant personnel are required to monitor the real-time temperature of the equipment, which increases the labor intensity of relevant personnel. Therefore, a crystallization device for low naphthalene aromatic solvents is proposed. Utility Model Content
