Description
技术领域 technical field
本实用新型属于树脂加工技术领域，具体涉及一种不饱和聚酯树脂生产装置。 The utility model belongs to the technical field of resin processing, in particular to an unsaturated polyester resin production device.
背景技术 Background technique
经过几十年的发展，以不饱和聚酯树脂为基体的玻璃钢制品已渗透到各行各业，在国民经济各个领域起着越来越重要的作用。但总的来说，国内的不饱和聚酯树脂的生产技术还远远落后于世界先进水平，具体表现在生产工艺落后、设备简陋、技术水平低等方面，因此不饱和聚酯树脂的产品质量不够稳定，性能不够理想。进入二十一世纪以来，随着国内外贸易的迅猛发展，国内不饱和聚酯树脂产品的生产技术水平落后的现象立刻显现出来。这样的严峻形势迫使国内的不饱和聚酯树脂生产企业不断改进、优化生产设施和工艺，以增加同国外同行的竞争力。反应釜是不饱和聚脂树脂缩聚反应过程中的关键设备，一般的反应釜是采用夹管加热，当釜的容积增加时，釜表面积增加的比例小于容积增加的比例，所以对于单位体积而言，有效的加热或冷却面积变小了，使得生产周期延长且难于控制,另外，反应过程生成的水受热形成水蒸气，从反应釜顶端排出，水蒸气中会夹杂较多的醇和酸，现有技术是在反应釜顶端直接连接分馏柱，分馏柱顶端依次连接竖式冷凝器和卧式冷凝器，通过分馏柱的分离，将水蒸气分离出，醇和酸回用，但是采用单一的分馏柱，其分离效果差，仍有部分的醇和酸损失，从而降低不饱和聚酯树脂的得率，且增加后续废水的处理难度。一次回收避免不了部分产品的流失，如果采用双层回收则将会大大提高树脂的取得率。 After decades of development, FRP products based on unsaturated polyester resin have penetrated into all walks of life and played an increasingly important role in various fields of the national economy. But generally speaking, the production technology of domestic unsaturated polyester resin is still far behind the world's advanced level, which is manifested in backward production technology, poor equipment, and low technical level. Therefore, the product quality of unsaturated polyester resin Not stable enough, performance is not ideal enough. Since entering the 21st century, with the rapid development of domestic and foreign trade, the phenomenon of backward production technology of domestic unsaturated polyester resin products immediately appeared. Such a severe situation forces domestic unsaturated polyester resin manufacturers to continuously improve and optimize production facilities and processes in order to increase their competitiveness with foreign counterparts. The reaction kettle is the key equipment in the polycondensation reaction process of unsaturated polyester resin. The general reaction kettle is heated by pinch tube. When the volume of the kettle increases, the ratio of the surface area of the kettle to increase is smaller than the ratio of the volume increase, so for the unit volume , the effective heating or cooling area becomes smaller, which makes the production cycle longer and difficult to control. In addition, the water generated in the reaction process is heated to form water vapor, which is discharged from the top of the reactor. The water vapor will be mixed with more alcohol and acid. The technology is to directly connect the fractionation column to the top of the reactor, and the top of the fractionation column is connected to a vertical condenser and a horizontal condenser in turn. Through the separation of the fractionation column, the water vapor is separated, and the alcohol and acid are reused, but a single fractionation column is used. Its separation effect is poor, and some alcohol and acid are still lost, thereby reducing the yield of unsaturated polyester resin and increasing the difficulty of subsequent wastewater treatment. One-time recycling cannot avoid the loss of some products. If double-layer recycling is used, the resin acquisition rate will be greatly improved.
