Double kettle continuous polymerization reaction deviceHigh pressure reaction vessels can be connected in series or in parallel. It is an efficient continuous production system designed with a series reaction kettle, whose core function is to optimize the polymer synthesis process through a multi-stage reaction process.

Structure composition and design characteristics of double kettle continuous polymerization reaction deviceDouble kettle series connection architecture, the device consists of two Senlang fully automatic reaction kettles, which achieve continuous material transfer through pipelines and pumping systems. The first reactor is usually used for monomer pre polymerization or primary polymerization, while the second reactor completes deep polymerization and product adjustment. Each kettle body is made of high temperature resistant and corrosion-resistant materials (such as 316L stainless steel), with a design pressure of up to 100 bar and a temperature control range of 50-250 ℃. The mixing system adopts a double-layer propulsion structure, and the mixing method of flipping up the lower layer and pressing down the upper layer can improve the uniformity of the reaction. The fully automatic continuous flow control unit is equipped with a precision metering pump to achieve continuous feeding of raw materials, and is connected to the vacuum machine through a vacuum tube to eliminate oxygen in real time to prevent polymer oxidation. The material transfer between the kettles adopts sealed conveying to avoid external environmental interference and ensure the stability of the reaction system. Key control system temperature control and pressure management dual display dual control temperature control system: the main control module monitors the temperature of the materials inside the kettle, and the auxiliary control module adjusts the temperature of the heating furnace with an accuracy of ± 1 ℃. Real time monitoring of pressure sensors, automatic triggering of safety interlock and cutting off heating when overpressure occurs. The 7-inch true color touch screen with automated operation interface supports modular parameter settings, and has functions of data acquisition, curve generation, and Excel export. Remote control is achieved through RS485 communication interface and supports MODBUS RTU protocol. The double kettle continuous polymerization reaction device has process advantages and application areas that improve efficiency and quality compared to the single kettle intermittent reactor. Continuous production reduces batch interval time and increases production capacity by more than 30%. By eliminating bubble units (such as defoaming needle and stirring linkage design) and vacuum deoxidation technology, the defect rate of the product can be significantly reduced.
