Description

TECHNICAL FIELD

[0001] The utility model relates to a chemical technology field, concretely relates to a kind of acrylic resin reaction kettle cooling water circulating device. BACKGROUND

[0002] In the field of chemical production, the synthesis of acrylic resin is a relatively common and important production process. Acrylic resin is widely used in coatings, adhesives, inks and many other industries due to its excellent weather resistance, water resistance, adhesion and other excellent properties, and has a large market demand.

[0003] During the production of acrylic resin, the reaction kettle is one of the core equipment, and chemical reactions such as polymerization occur inside. These chemical reactions often release heat, and if the heat cannot be effectively removed in time, it will cause the temperature in the reaction kettle to be too high, which will affect the normal progress of the reaction, the quality of the product, and the service life of the reaction kettle itself, etc. For example, excessive temperature may cause the reaction rate to be out of control, resulting in uneven product molecular weight distribution and gelation, and even safety accidents may occur.

[0004] Early small acrylic resin reaction kettles tried to rely on natural heat dissipation, that is, to dissipate heat through heat exchange between the reaction kettle itself and the surrounding environment. However, this method has very low heat dissipation efficiency and is only suitable for very small reaction scales and does not require high temperature control accuracy. With the continuous expansion of industrial production scale and the increasing demand for product quality, the natural heat dissipation method has been far from meeting the actual production needs.

[0005] Some enterprises use air cooling to dissipate heat by setting up a fan outside the reaction kettle to use air flow to carry away the heat on the surface of the reaction kettle. Although air cooling has certain advantages compared to natural cooling, it still has many shortcomings. On the one hand, the specific heat capacity of air is relatively small, and its heat absorption capacity is limited, so a high-power fan is often required to achieve good heat dissipation, resulting in high energy consumption. On the other hand, air cooling is greatly affected by environmental temperature, and in high-temperature environments, the cooling effect is greatly reduced, making it difficult to ensure stable temperature control in the reaction kettle, thereby affecting the stability of acrylic resin production and the consistency of product quality.

[0006] Currently, water cooling is one of the most common methods of heat dissipation for acrylic resin reaction kettles. Typically, cooling water is circulated through the jacket or coil of the reaction kettle to absorb the heat transferred from the inside of the reaction kettle, and then the heated cooling water is discharged and replaced with new cooling water for continuous circulation and heat dissipation.

[0007] However, traditional water cooling devices have many problems:

[0008] Cooling water waste problem: many existing water cooling devices simply discharge the cooling water after absorbing heat, and then supplement new cooling water, which causes a lot of waste of water resources, increases the production cost of enterprises, and does not meet the current energy saving and environmental protection requirements.

[0009] In summary, the existing acrylic resin reaction kettle cooling method, especially the water cooling device, has many problems to be solved in practical application, and an energy-efficient cooling device that can realize cooling water recycling, precise temperature control and energy saving is urgently needed to meet the demand for high-quality and high-efficiency production of acrylic resin.
