Straight pipe heat exchange type efficient polymerization reactor

Abstract

The invention discloses a straight pipe heat exchange type efficient polymerization reactor, which comprises a reactor body (1). The straight pipe heat exchange type efficient polymerization reactor has the characteristics that the central axis of the reactor body (1) is provided with a stirring shaft (2); the stirring shaft (2) is provided with a stirring blade (5); a material inlet (6) is installed on the position on the reactor body (1), which is opposite to the stirring blade (5); one end of the material inlet (6) is connected with a raw material conveying pipe; the other end of the material inlet (6) is connected with a spray nozzle (7); in the reactor body (1), a plurality of straight pipe type heat exchange pipe bundle groups (8) are arranged around the stirring shaft (2); each straight pipe type heat exchange pipe bundle group (8) comprises a plurality of straight pipe heat exchange pipes (9);a gap for a medium to be subjected to heat exchange in the spray nozzle (7) is left between the straight pipe heat exchange pipes (9) of each straight pipe type heat exchange pipe bundle group (8); the medium to be subjected to heat exchange passes through the gap to impact the straight pipe heat exchange pipes (9), and turbulence is formed in each straight pipe type heat exchange pipe bundle group (8) to quicken heat exchange; the adjacent straight pipe type heat exchange pipe bundle groups (8) are connected by a baffle (10) in the reactor; and the lower part of the reactor body (1) is provided with a material outlet (11). The straight pipe heat exchange type efficient polymerization reactor has the advantages of high efficacy and good heat exchange effect.

Description

technical field [0001] The invention relates to a reactor, in particular to a heat-exchange reactor, in particular to a straight-tube heat-exchange high-efficiency polymerization reactor. Background technique [0002] At present, since the stirring device needs to be installed in the polymerization reactor, there are mainly two ways of commonly used heat exchange devices, one is to install a heat exchange coil in the reactor, and the other is to install a heat exchange jacket outside the reactor. The problem with the coil heat exchange device is that during the stirring process, a vortex matching the coil spiral will be generated in the reactor, resulting in poor dispersion of raw materials, while the jacket heat exchange device has the problem of large volume and poor heat exchange effect. Therefore, it is urgent to design a reactor specially designed for polymerization with small volume and good heat exchange effect. Contents of the invention [0003] The object of ...
