Abstract

The invention discloses a rotary distribution and membrane flash evaporation specific gravity differential concentrator, and relates to a concentrator. The concentrator aims at the problem that the product quality is affected by the facts that the steam energy consumption of the existing concentrator is high, non-heat-resisting ingredients in the material liquid are easy to destroy, liquid and steam are easy to foam over in one chamber, and a great amount of electrical energy is consumed. A sealing cover is fixedly connected with an evaporating pot, a middle jacket, an outer jacket and a bottom jacket are arranged in the evaporating pot, the middle jacket is fixedly connected with the lower sealing end of the evaporating pot by a condensate water discharge pipe and two steam inlet pipes, the outer jacket is fixedly connected with the inner wall of the evaporating pot, the bottom jacket is fixedly connected with the inner wall of the bottom of the evaporating pot, the lower sealing endof the evaporating pot is communicated with a density measurement device which is communicated with a collection tank, the bottom of the collection tank is communicated with a total charging pipe by a discharging pipe, the total charging pipe is communicated with a first branch charging pipe which is communicated with a second branch charging pipe, two second steam inlets are arranged in the middle jacket, a first steam inlet is arranged in the outer jacket, and a third steam inlet is arranged in the bottom jacket. The concentrator is used for concentrating 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 ...
