Abstract

The invention relates to a film flash evaporation proportion difference type visible 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 the concentrators are difficult to clean and the cleanliness inspection is not easy to carry out after cleaning. The concentrator is characterized in that a seal cover is fixedly connected with an evaporating tank; an evaporating steam gathering tube is communicated with a vacuuming port; middle jackets are fixedly connected with the lower seal head of the evaporating tank via a condensed water drain pipe and two steam inlet tubes; outer jackets are fixedly connected with the inner walls of the evaporating tank; bottom jackets are fixedly connected with the lower seal head of the evaporating tank; the evaporating tank is communicated with a dasymeter; the dasymeter is communicated with a gathering tank; the gathering tank is communicated with a general feed 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 connected with a distributing device; two pair of sight glassed are installed in the outer wall of the evaporating tank; and the distances between the top end of the inner surface of the upper seal head of the evaporating tank and the top end faces of inner cylinders are not less than half of the total length of the evaporating tank. 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 ...
