Condensing device and method for diketene production

Abstract

The invention relates to the technical field of ketene dimer production, in particular to a ketene dimer production condensing device and method.The ketene dimer production condensing device comprises a condensing tower, a refrigerating machine and a plurality of condensing plates, the condensing plates are located in the condensing tower, and the condensing plates are located at different positions in the condensing tower; the adjusting pipe is arranged in the condensing tower, and a condensing medium is conveyed into the condensing plate through the adjusting pipe; when the diketene production condensing device and method are used, the diketene on the condensing plate can be ensured to be condensed at the optimal temperature by accurately controlling the conveying of the condensing medium, and the situation that the condensing temperature of the diketene is not enough after the condensing medium is heated due to heat exchange is avoided, so that the condensing speed is increased, the production efficiency is improved, and the production cost is reduced. And the uniform distribution of the temperature is beneficial to reducing the energy loss in the condensation process and improving the overall energy utilization efficiency.
