Abstract
The utility model discloses a solvent recovery vacuum drying system, which comprises a vacuum pump (1), wherein the vacuum pump (1) is connected with a liquid storage tank (3); the bottom of the liquid storage tank (3) is provided with a valve (5); the liquid storage tank (3) is connected with the outlet of a condenser (4); the inlet of the condenser (4) is provided with the valve (5); the inlet of the condenser (4) is connected with a vent of a vacuum dryer (6); the inlet of the vacuum dryer (6) is connected with a hot water tank (9); the liquid outlet of the vacuum dryer (6) is sequentially connected with the valve (5), a hot water tank electromagnetic valve bank (7), a suction pump (8) and a hot water tank (9); and the devices are connected through pipelines (2). The solvent recovery vacuum drying system has the advantages that a solvent is recovered and hot water is recycled.
Description
Technical field
The utility model relates to a kind of dehumidification system, is specifically related to a kind of solvent recuperation vacuum drying system.
Background technology
At present, conventional vacuum drying system all is that vacuum drier is joined vacuum pump and come work, and the solvent that vacuum pump extracts directly emits, owing to also contain some chemical substances usually in the solvent, directly discharges not only contaminate environment, has also caused waste.Feeding the hot water or the steam of vacuum drier, after temperature descends, also is directly to discharge through the water port of vacuum drier, does not realize the device of recycle, has wasted water resources.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of prior art, and a kind of solvent recuperation vacuum drying system is provided, and it has can reclaim the solvent that extracts, and can realize adding the advantage that hot water circulation is used.
The purpose of the utility model realizes through following technical scheme:
A kind of solvent recuperation vacuum drying system comprises vacuum pump, and vacuum pump is connected with container for storing liquid; The container for storing liquid bottom is provided with valve, and container for storing liquid is connected with the outlet of condensing surface, and the ingress of condensing surface is provided with valve; The import of condensing surface is connected with the venting port of vacuum drier; The import of vacuum drier is connected with hot well tank, and the leakage fluid dram of vacuum drier and valve, hot well tank SV group, lift pump, hot well tank are linked in sequence, and pass through pipe connection between each equipment.
Said vacuum drier is the hot-water type vacuum drier.
Can find out that through top narration the advantage of the utility model is; The solvent vapo(u)r that extracts is stored in the container for storing liquid after cooling off through condensing surface, has realized the recovery of solvent; It is logical to get back to hot well tank through lift pump after hot water in the vacuum drier is discharged, and has realized the recycle of hot water.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure, 1-vacuum pump, 2-pipeline, 3-container for storing liquid, 4-condensing surface, 5-valve, 6-vacuum drier, 7-hot well tank SV group, 8-lift pump, 9-hot well tank.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further, the protection domain of the utility model is not limited to the following stated.
As shown in Figure 1, a kind of solvent recuperation vacuum drying system comprises vacuum pump 1; Vacuum pump 1 is connected with container for storing liquid 3; Container for storing liquid 3 bottoms are provided with valve 5, and container for storing liquid 3 is connected with the outlet of condensing surface 4, and the ingress of condensing surface 4 is provided with valve 5; The import of condensing surface 4 is connected with the venting port of vacuum drier 6; The import of vacuum drier 6 is connected with hot well tank 9, and the leakage fluid dram of vacuum drier 6 and valve 5, hot well tank SV group 7, lift pump 8, hot well tank 9 are linked in sequence, and connects through pipeline 2 between each equipment.Vacuum drier 6 is the hot-water type vacuum drier.
The working process of the utility model is following:
Hot water in the hot well tank 9 gets in the vacuum drier 6 through pipeline 2; Temperature raises in the vacuum drier 6; The solvent that needs to contain in the drying objects gasifies, and the solvent of 1 pair of gasification of vacuum pump extracts, and cooling becomes liquid during solvent process condensing surface 4; Get in the container for storing liquid 3, realized the recovery of solvent; After hot water temperature in the vacuum drier 6 reduced, hot well tank SV group 7 was opened, and lift pump 8 work are drawn back the hot well tank heating with the hot water after the temperature reduction, have realized the recycle of hot water.
Claims (2)
1. a solvent recuperation vacuum drying system is characterized in that, comprises vacuum pump (1); Vacuum pump (1) is connected with container for storing liquid (3); Container for storing liquid (3) bottom is provided with valve (5), and container for storing liquid (3) is connected with the outlet of condensing surface (4), and the ingress of condensing surface (4) is provided with valve (5); The import of condensing surface (4) is connected with the venting port of vacuum drier (6); The import of vacuum drier (6) is connected with hot well tank (9), and the leakage fluid dram of vacuum drier (6) and valve (5), hot well tank SV group (7), lift pump (8), hot well tank (9) are linked in sequence, and connects through pipeline (2) between each equipment.
