Description
Technical field
The present invention relates to a kind of circumfluence distillation concentrator of improvement
Background technology
Low profile thermal refluxing extraction concentrator is mainly used in the industry such as medicine, spices extraction, and condensing mode adopts explosive evaporation mode, and evaporation rate is slow, and energy consumption is large, and the high-boiling time is long, and easily make effective ingredient react change, evaporant is easily in barrel coking; Many materials easily produce a large amount of foam when seething with excitement, original equipment is installed mesh mode and is tackled froth breaking at the vacuum suction mouth place of concentration tank, weak effect, the foam that can not produce boiling process in concentration tank carries out active to be eliminated, and the generation of foam simultaneously affects evaporation efficiency again.
Summary of the invention
For the deficiencies in the prior art part, the invention provides a kind of novel circumfluence distillation concentrator.Circumfluence distillation concentrator of the present invention takes full advantage of the cylindrical shell heat energy of more than liquid level, effective increase evaporating surface, have and improve thickening efficiency, guarantee concentrate uniform quality, shortening concentration time, the concentrated energy consumption of reduction, strengthen the advantage such as the defoaming capacity of concentration process, thorough solution barrel coking problem.
For achieving the above object, technical solution of the present invention is:
The circumfluence distillation concentrator improved, be at least made up of concentration tank, extractor, the pump housing and the circulation line that connects described concentration tank, extractor and the pump housing, described circulation line at least comprises pipeline I, and it is communicated with concentration tank, extractor and the pump housing; Pipeline II, it is communicated with and connects concentration tank and extractor; Pipeline III, it is communicated with the pump housing and pipeline II; Also comprise spray ring, its connecting pipeline II is fixed in concentration tank.
Described pipeline II is provided with valve, and this valve is arranged between concentration tank and pipeline III.
The described pump housing is screw pump.
Described spray ring lateral wall bottom is provided with more than one spray apertures, described spray apertures be arranged at depart from spray ring vertical center line 0-45 ° region in.
Described spray ring madial wall bottom is provided with more than one spray apertures, described spray apertures be arranged at depart from spray ring vertical center line 0-60 ° region in.
The usefulness of technique scheme is:
The feed centrifugal pump of existing equipment, on the basis of prior art circumfluence distillation concentrator, is replaced by screw pump by the present invention.Between the concentration tank and extractor of existing equipment, add a circulation line and add another circulation line between this circulation line and described screw pump.By setting up the spray ring in concentration tank, the concentrate of 2/3 flow can be made to spray to tank skin through the spray apertures of outer 0 ° to 45 ° of spray ring, flow down along tank skin, fully contact with heating surface and carry out heat exchange, forming film evaporation, increase disengagement area.The concentrate of the about 1/3 flow spray apertures of 0 ° to 60 ° in this spray ring is formed centrally random spray in concentration tank tank body, carries out froth breaking.The present invention is evaporated to master with film, and explosive evaporation is auxiliary, improves evaporation efficiency.The initial stage that the removal of foam can produce by spray froth breaking mode, is more effective froth breaking mode, decreases the foam produced in concentration tank, impact evaporation.Use screw pump can overcome centrifugal pump due to the negative pressure of suction inlet too low and produce cavitation erosion situation, guarantee that circulated sprinkling carries out.
