[0061] Example 2 A medium impact polystyrene resin production system
[0062] As a further improvement to Embodiment 1, the production system of this embodiment further includes a three-stage vacuum system.
[0063] The three-stage vacuum system includes a first-stage vacuum pump, a second-stage vacuum pump 8 and a third-stage vacuum pump 7; the third-stage vacuum pump 7 is arranged on the conveying pipeline of the devolatilizer and the circulating condenser 55; the second-stage prepolymerization reactor The top outlet pipeline of 32 is connected in parallel with the top outlet pipeline of the first-stage devolatilizer 61 through the first reflux condenser 52, and then connected with the second-stage vacuum pump 8 through the circulating condenser 55 and then connected with the first-stage vacuum pump; The outlet pipeline of the secondary devolatilizer 62 is connected to the circulating condenser 55 after passing through the second reflux condenser 54 and the third stage vacuu...
Example Embodiment
[0066] Example 3 A medium impact polystyrene resin production system
[0067] like figure 2 As shown, as a further improvement to Embodiment 1, the production system of this embodiment further includes a total heat transfer oil system.
[0068] The total heat transfer oil system includes a heat transfer oil circulation system and a heat transfer oil intelligent temperature control system. The heat-conducting oil intelligent temperature control system connects the heat-conducting oil pipeline with the inner coil and the outer jacket of the reactor to form a heat-conducting oil circulation system. Under normal circumstances, the temperature of the polymerization reactor is controlled by the heat transfer oil circulation of the inner coil and the outer jacket, and the reaction heat generated by the polymerization reaction is removed in time. Cool quickly.
[0069] The heat-conducting oil intelligent temperature control system consists of a hot-conducting oil storage tank 801 ...
