Abstract

The invention relates to a film flash evaporation proportion difference type concentrator. The invention aims at the following problems of the current concentrators: the steam energy consumption is high; the non-heat-resistant components in the material liquid are easy to destroy; foaming over is easy to happen when the liquid and the steam are in the same chamber; and lots of power energy is consumed. The concentrator is characterized in that the bottom of a seal cover is fixedly connected with the outer wall of the upper seal head of an evaporating tank; the upper seal head of the evaporating tank is provided with a vacuuming port; the other end of an evaporating steam gathering tube is communicated with the vacuuming port; outer jackets are arranged inside the evaporating tank; the diameters of the top and bottom of the outer jackets are gradually expanded; the two ends of the outer jackets are fixedly connected with the inner walls of the evaporating tank; the lower seal head of the evaporating tank is communicated with the inlet end of a dasymeter; the outlet end of the dasymeter is communicated with a gathering tank; the bottom of the gathering tank is communicated with a general feed tube via a discharge tube; the general feed tube is communicated with one end of a first branch feed tube; the other end of the first branch feed tube is communicated with a second branch feed tube; and a first steam inlet is arranged on one outer jacket. The concentrator is used for concentrating the material liquid.

Description

technical field [0001] The present invention relates to a concentrator. Background technique [0002] The existing concentrators are divided into seven types: vacuum decompression concentrator, falling film evaporator, external circulation evaporator, double (three) effect falling film evaporator, double (three) effect external circulation evaporator, Forced circulation evaporator and scraper concentrator; the common shortcomings of the above concentrators except the scraper concentrator are: the influence of the static pressure head in the evaporator and the frictional resistance generated by the fluid flowing through the heating tube lead to a further increase in the boiling point of the solution, The consumption of steam energy is high; during the concentration process, the feed liquid is continuously heated during concentration, and the cycle heating time is long, and the heat-resistant components in the feed liquid are easily damaged; the temperature of the feed liquid ...
