The inventiondiscloses a falling film evaporator for manufacturing textile polyester finishing agent, which comprises a housing, an upper head, and a lower head; the housing is connected to the upper head and the lower head; the upper head is provided with a vacuum tube; the lower head is provided with a concentrated solution discharge tube; a top of an inner cavity of the housing is provided with an inlet tube, and a discharge end of the inlet tube is provided with a plurality of nozzles; an upper end of the inner cavity of the housing is provided with a liquid distribution plate under the nozzles, and the liquid distribution plate is provided with a plurality of falling film evaporation tubes; a steam washing tube is provided over the liquid distribution plate; an outer wall of the housing is provided with a steam tube, a lower part of the outer wall of the housing is provided with a steam dewatering tube. According to the evaporator provided by the invention, by means of preservative treatment on the inner wall of the falling film evaporation tubes by coating epoxy resin, the service life of the device is prolonged. Meanwhile, special designs are made for various falling film evaporation tubes, so that fluid materials evenly flow into each of the falling film evaporation tubes to avoid a phenomenon of dry blowing, and the falling film evaporation efficiency is increased.
Description
technical field [0001] The invention belongs to chemical equipment, in particular to a falling film evaporator for producing textile polyester finishing agents. Background technique [0002] Textile finishing agents are used to endow textiles with excellent properties such as use, safety, and appearance in order to meet certain special requirements for textiles. It is a kind of functional finishing agent developed by the development of multidisciplinary technology such as ecology and ecology. Because the functional finishing of textiles is aimed at some specific properties of textiles, it has strong purpose, good effect and high added value of products. After functional finishing, textiles have clear purpose and scope of use, and are also popular among consumers. [0003] The falling film evaporator is to add the feed liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into each heat exchange tube through the liqui...
