Embodiment 1

[0008] Embodiment 1: its composition is as figure 1 . The drum 2 of the reaction device is made of stainless steel, with a diameter of 1m and a length of 2m. The rotating speed is controlled by a speed changer, and the rotational speed of the drum 2 is 0.5 / min. Consists of 2 reactors. The feeder 1 is in the shape of a flat mouth funnel, and the length is 2m; the diameter of the support wheel 3 is 0.1m, and the length is 2m, a total of 6 pieces, and one piece is installed every 30° from the right end of the horizontal horizontal center line of the drum 2; the diameter of the guide wheel 5 is 0.2m , 2m long, installed at 15° below the left end of the horizontal horizontal centerline of the drum 2. The second reactor is located at the bottom left of the first reactor, and its horizontal vertical centerline is 0.7m away from the horizontal vertical centerline of the first reactor. 3 Install 6 support rollers 3 on the same position, and install 2 support rollers 3 every 30° upwa...

Embodiment 2

[0009] Embodiment 2: Consists of one reactor. The drum 2 is made of stainless steel, with a diameter of 2m and a length of 3m, and its rotational speed is 0.25m / min; the feeder 1 is in the shape of a funnel with a flat mouth, and the length is 3m; the supporting roller 3 has a diameter of 0.2m, a length of 3m, and 6 supporting rollers 3 Install evenly every 30° from the right end of the horizontal horizontal centerline of the drum 2; the guide wheel 5 has a diameter of 0.4m and a length of 3m, and is installed at 15° below the left end of the horizontal horizontal centerline of the drum 2.

[0010] In the present invention, because the polymer monomer and the catalyst are mixed and evenly distributed on the drum 2 with a flowing heat exchange medium for heat dissipation, the polymerization reaction is performed, the heat exchange is good, implosion can be completely prevented, continuous production is possible, and the production efficiency is high. , The polymerization produc...

Abstract

The invention provides a reaction device. It assembles a set of reactors below the filler in the container, or further it is connected with one or several reactors in series, under the lowest grade of reactor there has a transmission belt and finished product cabinet. The reactor is made up of rotation wheel, supporting wheel, scraper, guiding wheel and heat exchanging media inlet and outlet. The device has a high heat exchanging efficiency, and it is very simple.

Description

[0001] Involved areas [0002] The invention is a reaction device used for preventing implosion in bulk polymerization process. Involves the general field of chemical installations and piping systems. Background technique [0003] The bulk polymerization process is a process widely used in the synthesis of ultra-high molecular weight polymers. However, most polymerization reactions are exothermic reactions. If the heat generated by the reaction cannot be discharged in time, implosion polymerization will easily occur, which will affect the performance of the polymer. In order to prevent detonation, two methods are usually adopted. One is to use microcapsule technology, that is, to use special coating materials to make microcapsules (particle size less than 0.25cm) made of polymer monomers and catalysts into the heat exchange medium. It is a continuous phase and has a large volume, which can quickly remove the heat of reaction. But this method equipment is complicated, and i...
