Abstract
The utility model discloses a forced circulation double-effect evaporator, which comprises a first-level heat exchanger. The first-level heat exchanger is communicated with a first-level evaporation chamber communicated with a second-level heat exchanger, the second-level heat exchanger is communicated with a second-level evaporation chamber communicated with a condenser, and a receiving tank is arranged on the bottom of the condenser. The bottoms of the first-level heat exchanger and the first-level evaporation chamber are communicated through a pipe, and a first-level forced circulation pump is arranged on the pipe. The bottoms of the second-level heat exchanger and the second-level evaporation chamber are communicated through a pipe, and a second-level heating circulation pump is arranged on the pipe. By means of the forced circulation double-effect evaporator, during an evaporation process, materials are high in flowing rate, even in heating, high in coefficient of heat transfer and free of dry-wall phenomena when heated by forced circulation, the materials can rapidly enter a heat exchange pipe through forced circulation pumps and be vibrated in a vibration device so as to vibrate a heating pipe, thereby enabling attachments on a pipe wall to fall off and preventing the materials from attaching on a wall.
Description
Technical field
The utility model relates to a kind of medication chemistry apparatus, particularly a kind of forced circulation double effect evaporator.
Background technology
Traditional concentrator mostly adopts the direct heat form of steam, and power consumption is high, and concentration time is long, and the domestic in recent years double effect evaporator that generally adopts concentrates.Double effect evaporator is a kind of concentrator based on low-temperature operation and energy consumption saving, has been widely used in the pharmaceuticals industry, and the cryogenic vacuum that is particularly useful for heat sensitive material concentrates, and is the common equipment of present medical extract concentration process.Primary steam enters the one-level heating clamber feed liquid is heated, and moisture content is evaporated rapidly under the effect of vacuum, and the indirect steam that is evaporated enters the secondary heating clamber and gives the heating of secondary feed liquid, forms second circulation.The steam that the dual evaporation chamber is evaporated enters cooler, is cooled to condensed water, flows into the drop pan place and drains, and the water in the feed liquid constantly is evaporated, and concentration is improved, up to needed proportion.But concentrating easy fouling when fouling tendency, crystallinity, high viscosity being arranged and containing the feed liquid of insoluble solid, separate out crystallization etc., cause that flowing velocity reduces in the heat exchanger, it is inhomogeneous to be heated, and causes the phenomenon of dried wall, and concentrated effect reduces greatly.
The utility model content
The technical problems to be solved in the utility model is the deficiency at technique scheme, provides to quicken the circulation of heat exchanger feed liquid, a kind of forced circulation double effect evaporator that evaporation effect is good.
For addressing the above problem the technical solution of the utility model be:
