Embodiment Construction

[0049] attached by figure 1 Shown: The production equipment of this polyethylene oxide product includes:

[0050] A polymerization reactor, by adding solvent, catalyst and ethylene oxide for polymerization reaction to generate a polymer; avoiding the phenomenon of partial detonation in the reaction, so that the volume of the reactor is enlarged to 6000 liters;

[0051] An integrated equipment, which integrates filtration, drying and washing, is used to solve the problems of fire prevention, explosion prevention, dust prevention and nitrogen loss in this production step;

[0052] A finished product mixing tank, so that the material can achieve a very uniform mixing degree after adding modifiers in the finished product mixing tank, ensuring the stability of product quality;

[0053] A solvent recovery tank, a still, a hexane storage tank and an unqualified hexane storage tank are used to recover and reuse the reaction solvent.

[0054] The production process of the polyethylen...

Abstract

The invention relates to production equipment for polyoxyethylene products and a preparation method thereof. The equipment comprises a polymerization reaction kettle, integrated equipment, a finished product mixing kettle, a solvent recycling tank, a distillation kettle, a hexane storage tank and an unqualified hexane storage tank. The production process of the polyoxyethylene products comprises the steps that ring opening polymerization is performed on ethylene oxidein C6 or C7 solvent through the action of a catalyst, exothermic reaction is performed at a certain temperature and under certain pressure, and the requirements of product specifications are achieved through the growth of polymeric chains; after the reaction is finished, the products are processed through the integrated equipment with the functions of filtering, drying and washing, and then packaging is performed. According to the production equipment for the polyoxyethylene products and the preparation method thereof, the partial implosion phenomenon caused by the reaction is avoided, the volume of the reaction kettle is successfully enlarged to 6000 litres, the production scale of a PEO device is enlarged, and the stability of the product quality is improved; the method solves the problems of solvent dehydrating and solvent recycling and reusing.

Description

technical field [0001] The invention belongs to the field of chemical raw material production, in particular to a production equipment for polyethylene oxide products and a preparation method thereof. Background technique [0002] Polyethylene oxide, referred to as PEO, is obtained by ring-opening polymerization of ethylene oxide (also known as ethylene oxide). It is an important water-soluble polymer material with a wide range of applications, including papermaking, electrical appliances, construction, mining, medicine, agriculture, textiles, printing, oil exploration, municipal engineering, washing and personal care products, etc. [0003] The brief description of its production principle and process is: Ethylene oxide undergoes ring-opening polymerization through the action of a catalyst in a solvent such as C6 or C7, and undergoes an exothermic reaction at a certain temperature and pressure. Through the growth of the polymer chain, the requirements of the product molecu...
