Embodiment Construction

[0047] figure 1 shows a reactor with three reaction zones for continuous degassing of reaction products made from carboxylic acids of a multifunctional alcohol. The reactor has three hydraulic drives 1a, 1b and 1c for the three rotors of reaction zones I, II and III. The drive means for each rotor are respectively connected to the hydraulic system via a feed line 5 and a return line 6 . The hydraulic drive is characterized by a low mass, a controllably low rotational speed, an adjustable reaction using the operating parameters of the drive. The rotor of reaction zone II is fastened on a straight main shaft 25 which is supported on the left in the inner bearing of the hollow shaft of the rotor of reaction zone I and on the right in the inner bearing of the rotor of reaction zone III. The rotor of reaction zone I is fastened on a hollow shaft 26a which is supported on the left side on the end face of the reactor and on the right side on the main shaft. The rotor of reaction z...

Abstract

The invention relates to a device for continuously degasifying reaction products of a carboxylic acid or dicarboxylic acid with a multifunctional alcohol, which can be used for creating intrinsic viscosities of up to 0.9 dl / g. The product is distributed onto the reaction area located in the inlet section via slot nozzles (16) at the inlet into the reactor before running down to the bottom while required reaction surface of the product is additionally created in a proactive manner by means of a product receiving device (17). The inventive reactor is composed of several reaction zones which aredriven by separately operated rotors encompassing associated hydraulic systems, respectively, said hydraulic systems being installed outside the reactor. Measurable variables from the mode of operation of the hydraulic systems are used for controlling the reaction of the product in order to influence the obtention of predefined product parameters and qualities. The reactor is provided with one orseveral individual product outlets according to the product properties that are to be obtained.

Description

technical field [0001] The invention relates to a reactor for flowable highly viscous or pasty media. Background technique [0002] DE-OS 102 00 230 A1 describes a stirring drive for vertical and horizontal reactors, which is designed as a hydraulic motor. The arrangement of the motor is carried out directly in the reactor, wherein the product charged into the reactor serves as the hydraulic medium for the drive. The hydraulic medium is fed to the drive via pipelines, and the drive energy is generated by an external pump station. After the drive power for the stirrer has been transferred, the product is introduced as a reactant into the reactor and leads to a further reaction there. [0003] In this variant, if the drive mechanism arranged in the reactor fails or is damaged, the reaction process must be stopped and repaired by opening to the atmosphere. Furthermore, no control of the process is used in this case by using the signals from the measured values ​​of the drive...
