Description
Technical Field
The utility model relates to a enrichment facility of traditional chinese medicine trade, in particular to low temperature countercurrent concentrator.
Background
At present, in the domestic traditional Chinese medicine equipment manufacturing industry, a designed traditional Chinese medicine concentrator adopts a combination form of single-effect and double-effect cooling water cooling and steam heating concentration, the water consumption of cooling water of the concentrator is large, materials cannot be preheated (or need steam heating for preheating), the steam consumption is large, the temperature difference of the materials is large when the materials at normal temperature or low temperature are concentrated, the process of instantaneously reducing evaporation capacity and vacuum degree exists in the feeding process, the energy consumption of the concentrating equipment is large, the operation is unstable, and the problem puzzling pharmaceutical enterprises is solved.
Disclosure of Invention
In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a low temperature countercurrent concentrator with low energy consumption and stable operation.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to accomplish:
the low-temperature countercurrent concentrator is characterized in that: including the second grade condenser, the second grade condenser is equipped with export intercommunication cooler, the cooler is located in the one-level condenser, the cooler is equipped with export intercommunication feeding governing valve, the feeding governing valve is equipped with export intercommunication evaporimeter, the evaporimeter is equipped with the exit of importing and exporting the intercommunication heater, the top of evaporimeter is equipped with gas phase outlet intercommunication demister, demister is equipped with export and even ventilates the liquid separator, gas-liquid separator is equipped with export intercommunication one-level condenser, the one-level condenser is equipped with export intercommunication second grade condenser, the bottom of one-level, second grade condenser is equipped with the fluid collection tank.
The cooler is a coil cooler.
The heater and the primary condenser adopt tube type heat exchangers.
The low-temperature countercurrent concentrator adopting the technical scheme comprises a heater, an evaporator, a gas-liquid separator, a primary condenser, a cooler, a secondary condenser, a valve and the like, wherein the heater adopts a tube type heat exchanger, the diameter of a heat exchange tube is DN32, the tube diameter wall is 45, the structure of an upper tube plate and a lower tube plate is adopted, the flow velocity of a concentrated solution in the tube is more than or equal to 3m/s, an inner mirror tube is purchased in the tube, so that materials are not easy to stick to the wall, the concentrated solution entering the evaporator by the heater enters in a tangential cyclone micro-ascending manner, so that gas-liquid centrifugal separation can be well carried out on the wall surface of the evaporator, and gas can continuously and rotatably ascend against the wall surface of the evaporator under the influence of the upper vacuumizing force, and a liquid phase can continuously descend under the action; the secondary steam rises and enters a primary condenser after foam removal and gas-liquid separation, for low-temperature materials, the primary condenser is cooled by cooling water, the primary condenser adopts a tube type heat exchanger and adopts a double-tube-layer structure, the tube layer is communicated with the cooling water, the shell layer is communicated with the secondary steam, the secondary steam is cooled by a coil type cooler after the primary condensed material, the cooler is internally communicated with the low-temperature material, the outer layer of the coil is communicated with secondary steam condensate, uncooled steam of the primary condenser enters a shell of a secondary condenser for cooling, the tube layer of the secondary condenser is communicated with the low-temperature material, the material of the low-temperature material enters the coil type cooler through the secondary condenser and then enters an evaporator, the low-temperature material is gradually heated by the waste heat of the secondary steam, so that the heat absorption of the secondary steam is realized, and the heat of the secondary steam can be collected at, meanwhile, the air suction quantity of the whole vacuum pump after the vacuum degree is improved.
