Abstract
The utility model discloses an organic solvent recovery unit among wet article dry run of diphenyl sulphone (DPS), include vacuum dryer, vacuum dryer's top is equipped with wet article feed inlet, and the bottom is equipped with the export of drying article, and inside is equipped with vacuum filter, and vacuum filter passes through the connecting pipe and is connected with the air inlet of buffer tank, and the gas outlet of buffer tank is connected with the air inlet of vacuum pump, is equipped with freezing condenser between the gas outlet of vacuum pump and the air inlet of receipt jar, and the gas outlet of receiving the jar is connected with water -cooled condenser, and water -cooled condenser's top is equipped with the evacuation pipe. The utility model discloses a recovery unit freezes the condensation after the vacuum pump exhaust and water -cooling condensation two -stage is retrieved, and discharge to reach standard is guaranteed in organic solvent's thorough recovery among the wet article dry run of realization diphenyl sulphone (DPS), has effectively reduced the waste of environmental pollution and raw materials.
Description
Technical field
The utility model relates to a kind of retracting device, is specifically related to the organic solvent recovery device in a kind of diphenyl sulphone (DPS) wet product dry run.
Background technology
Diphenyl sulphone (DPS) production process is purified by carry out recrystallization to the wet product containing organic solvent, then obtain dry finished product by the mode that centrifugal solid-liquid is separated.The residual quantity of organic solvent is about 8-10%; organic solvent is removed by vacuum drying; in order to realize the recovery of organic solvent; usual meeting increases one-level water-cooled condenser before vavuum pump is bled; because before the vavuum pump later stage, negative pressure is higher, cause organic solvent boiling point to reduce, condensation is reclaimed not thorough; part organic solvent is directly discharged in air, brings serious pollution to environment.
Therefore, a kind of new technical scheme is needed to solve above-mentioned technical problem.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of retracting device that thoroughly can reclaim the organic solvent in diphenyl sulphone (DPS) wet product dry run.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Organic solvent recovery device in diphenyl sulphone (DPS) wet product dry run, comprise vacuum desiccator, surge tank, vavuum pump and receiving tank, the top of vacuum desiccator is provided with wet product charging aperture, bottom is provided with dry product outlet, inside is provided with vacuum filter, vacuum filter is connected with the air inlet of surge tank by tube connector, the gas outlet of surge tank is connected with the air inlet of vavuum pump, freezer condenser is provided with between the gas outlet of vavuum pump and the air inlet of receiving tank, the gas outlet of receiving tank is connected with water-cooled condenser, and the top of water-cooled condenser is provided with evacuated tube.
As preferably, above-mentioned vacuum desiccator is double cone rotating vacuum drier.
Compared with prior art, the utility model has the advantages that: retracting device of the present utility model after vacuum pump discharges, carry out refrigerated condensation and water-cooled condensation two-stage reclaims, realize the thorough recovery of organic solvent in diphenyl sulphone (DPS) wet product dry run, guarantee qualified discharge, effectively reduce the waste of environmental pollution and raw material.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, double cone rotating vacuum drier, 11, wet product charging aperture, 12, dry product outlet, 13, vacuum filter, 2, surge tank, 3, vavuum pump, 4, receiving tank, 5, freezer condenser, 6, water-cooled condenser, 7, tube connector, 8, evacuated tube.
Detailed description of the invention:
As shown in Figure 1, organic solvent recovery device in diphenyl sulphone (DPS) wet product dry run, comprise double cone rotating vacuum drier 1, surge tank 2, vavuum pump 3 and receiving tank 4, the top of double cone rotating vacuum drier 1 is provided with wet product charging aperture 11, bottom is provided with dry product outlet 12, inside is provided with vacuum filter 13, vacuum filter 13 is connected with the air inlet of surge tank 2 by tube connector 7, the gas outlet of surge tank 2 is connected with the air inlet of vavuum pump 3, freezer condenser 5 is provided with between the gas outlet of vavuum pump 3 and the air inlet of receiving tank 4, the gas outlet of receiving tank 4 is connected with water-cooled condenser 6, the top of water-cooled condenser 6 is provided with evacuated tube 8.
Diphenyl sulphone (DPS) wet product enters in double cone rotating vacuum drier 1 from wet product charging aperture 11 carries out drying purification, the gaseous state organic solvent produced in dry run enters in surge tank 2 from tube connector 7 after vacuum filter 13 filters, then under the effect of vavuum pump 3, enter condensation in freezer condenser 5 and water-cooled condenser 6 successively reclaim, be pressure-fired because vavuum pump 3 is vented rear pressure, the boiling point of organic solvent obviously promotes relative to negative pressure state, and then promote the condensed in two stages temperature difference, condensation recovering effect is good, the gas of discharging in evacuated tube 8 is almost pollution-free to environment, effectively reduce the pollution to environment in diphenyl sulphone (DPS) production process, diphenyl sulphone (DPS) product after dry purification exports 12 from dry product and takes out, product purity is good, meet technological requirement.
Claims (2)
1. the organic solvent recovery device in diphenyl sulphone (DPS) wet product dry run, it is characterized in that: comprise vacuum desiccator, surge tank, vavuum pump and receiving tank, the top of described vacuum desiccator is provided with wet product charging aperture, bottom is provided with dry product outlet, inside is provided with vacuum filter, described vacuum filter is connected with the air inlet of surge tank by tube connector, the gas outlet of described surge tank is connected with the air inlet of vavuum pump, freezer condenser is provided with between the gas outlet of described vavuum pump and the air inlet of receiving tank, the gas outlet of described receiving tank is connected with water-cooled condenser, the top of described water-cooled condenser is provided with evacuated tube.
