Summary of the invention
The purpose of this utility model is to provide a kind of organic solvent gathering-device for the board-like freeze dryer of triple heat exchanges, can thoroughly reclaim organic solution and avoid diffusing to environment.
Organic solvent gathering-device for the board-like freeze dryer of triple heat exchanges of the present utility model, is connected in condenser, and the inner chamber of condenser is settled triple heat exchanger plates, and its top of condenser is provided with mist entrance, is mounted with solvent catch tray in its underpart, described organic solvent gathering-device comprises: solvent collector, condenser draining main valve, cooling coil, compressor, condenser draw a mouthful valve, vavuum pump, collector and draw a mouthful valve, balanced valve, collector vent valve, described solvent collector is placed in the below, bottom of described condenser, described condenser draining main valve is connected with the bottom of described condenser with described solvent collector by pipeline, described cooling coil is arranged in the inner chamber of described solvent collector, and be connected in compressor by pipeline, so that compressor carries out solvent collector described in separate refrigeration, described condenser draws a mouthful valve, vavuum pump, collector draw mouthful valve be connected in series in by pipeline shown in condenser and shown between solvent collector, described balanced valve, collector vent valve is connected between described condenser and described solvent collector by pipeline, so that described condenser and described solvent collector are connected.
Described solvent collector is provided with solvent collector draining valve and row's solvent valve, and solvent collector draining valve is discharged the condensed water in solvent collector by pipeline by discharge outlet, and row's solvent valve is discharged the solvent liquid of collecting by pipeline by arranging solvent mouth.
The housing of described solvent collector and described cooling coil adopt stainless steel manufacture.
In the cavity of described solvent collector, be also provided with by the cooling coil of compressor separate refrigeration.
The utility model is to place catch tray in the bottom of condenser, connect solvent collector by condenser draining main valve, and in solvent collector, install one group of cooling coil additional, use compressor to carry out separate refrigeration, therefore can more effective collection organic solvent, avoid organic solvent to affect freeze-drying, and can make the temperature in solvent recover lower than condenser surface, solvent reclaims more thorough.。
Brief description of the drawings
Fig. 1 is the layout drawing of the organic solvent gathering-device for the board-like freeze dryer of triple heat exchanges of an embodiment of the utility model.
Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.First it should be noted that, the utility model is not limited to following detailed description of the invention, the spirit that those skilled in the art should embody from following embodiment is understood the utility model, and each technical term can be done the most wide in range understanding based on Spirit Essence of the present utility model.Identical Reference numeral represents identical part in the accompanying drawings.
As shown in Figure 1, the organic solvent gathering-device for the board-like freeze dryer of triple heat exchanges of an embodiment of the utility model, be connected in condenser 1, the inner chamber of condenser 1 is settled triple heat exchanger plate 1a, condenser 1 its top is provided with mist entrance 1b, is mounted with solvent catch tray 1c in its underpart, solvent gathering-device comprises: solvent collector 6, condenser draining main valve 5, cooling coil 6a, condenser draw mouthful valve 2, vavuum pump 3, collector and draw a mouthful valve 6d, balanced valve 4, collector vent valve 6e, solvent collector 6 is placed in the below, bottom of condenser 1, condenser draining main valve 5 is connected with the bottom of described condenser with solvent collector 6 by pipeline, cooling coil 6a is arranged in the inner chamber of described solvent collector 6, and be connected in compressor 7 by pipeline, so that compressor carries out solvent collector 6 described in separate refrigeration, described condenser draws mouthful valve 2, vavuum pump 3, collector draws mouthful valve 6d and is connected in series between condenser 1 and solvent collector 6 by pipeline, described balanced valve 4, collector vent valve 6e is connected between condenser 1 and solvent collector 6 by pipeline, so that condenser 1 and solvent collector 6 are connected.Described solvent collector is also provided with solvent collector draining valve 6b, 6c and row's solvent valve 6d, solvent collector draining valve 6b, 6c are discharged the condensed water in solvent collector 6 by pipeline by discharge outlet 8, row's solvent valve 6d discharges the solvent liquid of collecting by pipeline by arranging solvent mouth 9.
The collection process that the organic solvent gathering-device for the board-like freeze dryer of triple heat exchanges of above-described embodiment carries out organic solvent is as follows.
Open collector and draw mouthful valve 2 and condenser 1, vacuumize by vavuum pump 3, and open condenser draining main valve 5 and balanced valve 4, so that condenser 1 and solvent collector 6 are communicated;
Start compressor 7 with by cooling coil 6a refrigeration solvent collector 6, make the temperature of its temperature lower than condenser 1;
