Abstract

The invention relates to a rectification device for improving recovery rate. The device comprises a rectification tower, a reboiler and a pipe bundle condenser. The pipe bundle condenser is provided with a gas inlet, a venting port, a cooling water inlet, a cooling water outlet and a condensate liquid outlet. The gas inlet is connected to a gas phase pipe port. A gas guide cylinder is disposed at the upper part in the rectification tower close to the gas phase pipe port, and a smooth rotary shaft and a plurality of guide vanes are disposed in the guide cylinder, the guide cylinder is a vertically placed circular cylinder with a smooth and flat internal wall surface, and the diameter of the circular cylinder is 5-30cm larger than that of the gas inlet. The plurality of guide vanes are fixed on the rotary shaft. The rectification tower, the gas guide cylinder pipe bundle condenser's material pipe side inner walls, the smooth rotary shaft and the guide vanes are all coated with a layer of corrosion resistant and smooth coating. The rectification device provided by the invention can realize smooth access of gas into the pipe bundle condenser so as to accelerate material circulation, and also the defect that incomplete recovery of raw materials on the inner walls of each apparatus causes waste can be overcome.

Description

technical field [0001] The invention relates to a rectification device with improved precision, which belongs to the field of chemical processing equipment. Background technique [0002] In the existing rectification tower, steaming is used to make the raw material carry out the rectification process in the tower. In actual production, it is impossible to maintain the temperature in the rectification tower and ensure that the raw material completely enters the cooling pipe for rectification. Therefore, because The raw materials that have cooled down and returned to liquid state will be recovered through the residue pipe to continue rectification, but the raw materials adhered to the inner wall of the rectification tower cannot be fully recovered, resulting in waste; at the same time, the product recovery rate of the traditional rectification tower is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rectific...
