Problems solved by technology

Since the general polymer reaction monomer polymerization process is continuous feeding, accompanied by a violent exothermic reaction process, the conventional temperature adjustment method generally adopts the method of feeding steam or refrigerant into the reactor jacket to control the temperature rise and fall. This method has poor temperature control accuracy and high energy consumption. In addition, the heat and cold exchange of the jacket of the reactor is too fast, and the temperature changes too much, which affects the life of the reactor.

Abstract

The invention discloses a reactor with adjustable interior and exterior temperatures, comprising a reactor body, a reactor jacket, a stirring device and a reactor support. The reactor jacket is disposed outside the reactor body; an external heat exchange chamber is formed between the reactor jacket and the reactor body; the stirring device is disposed on a center line of the reactor body; the stirring device comprises a servo motor, a stirring shaft and stirring blades; the stirring shaft is provided with a stirring shaft through hole along its center axis; the part of the bottom of the reactor body in contact with the stirring shaft is provided with a stirring device water inlet; the part of the upper portion of the reactor body in contact with the stirring shaft is provided with a stirring device wat4er outlet; both the stirring device water inlet and the stirring device water outlet are communicated with the stirring shaft through hole; the stirring blades are of sector blade structure; the stirring blades are connected with the stirring shaft by welding. The use of the sector stirring blades enlarges heat transfer contact area, and the stirring shaft is hollowed and filled with a heat transfer medium so that the interior temperature of the reactor can be adjusted precisely.

Description

technical field [0001] The invention relates to the field of pressure vessels, in particular to an internally and externally regulated temperature reactor. Background technique [0002] At present, the synthetic method of polymer generally adopts to put several kinds of polymer reaction monomers into the reactor to carry out polymerization reaction at the same time. Polymer reaction monomers will absorb heat or exotherm during the polymerization reaction, and temperature control has a great effect on the selectivity and yield of reaction substances. During the reaction process of the polymer reaction monomer, the temperature needs to be raised to induce the reaction at the beginning, and a large amount of heat is released after entering the reaction process, and the heat needs to be removed quickly. In order to control the reaction temperature well, ensure the reaction speed and stabilize the product quality. Since the general polymer reaction monomer polymerization proces...
