Abstract
The utility model discloses a liquid ring vacuum pump closed loop system, it includes liquid ring vacuum pump (1), vapour and liquid separator (2) and heat exchanger (3), the outlet of liquid ring vacuum pump (1) and the access connection of vapour and liquid separator (2), the leakage fluid dram of vapour and liquid separator (2) and the access connection of heat exchanger (3), the export of heat exchanger (3) is connected with the water supply mouth of liquid ring vacuum pump (1). It also comprises a vacuum check valve (4) and a booster pump (5). The utility model has the advantages of, can not cause the pollution to the environment, organic solvent easily retrieves.
Description
Technical field
The utility model relates to a kind of vacuum withdraw device, is specifically related to a kind of liquid-ring vacuum pump closed-loop system.
Background technique
In traditional liquid ring vacuum pumping system, the water that liquid-ring vacuum pump is discharged gets into big circulating water pool or directly drains.This drainage pattern is easy to connect, uses simply, in practical application, is adopted morely.If but contained organic solvent or toxic substance by in the medium that extracts; There is following shortcoming in the method that adopts working solution directly to discharge: liquid-ring vacuum pump is when extracting gases; Pumped gas mixes with working solution; Can contain part organic solvent or toxic substance in the water that drain opening is discharged, can pollute environment; The organic solvent that is drawn out of is difficult for reclaiming, and has caused waste.
The model utility content
The purpose of the utility model promptly is to overcome the deficiency of existing technology, provides a kind of and can not pollute environment, the liquid-ring vacuum pump closed-loop system of easily-recovered organic solvent.
The purpose of the utility model realizes through following technological scheme:
The liquid-ring vacuum pump closed-loop system; It comprises liquid-ring vacuum pump, gas-liquid separator and heat exchanger; The drain opening of liquid-ring vacuum pump is connected with the import of gas-liquid separator, and the liquid port of gas-liquid separator is connected with the import of heat exchanger, and the outlet of heat exchanger is connected with the water-supplying mouth of liquid-ring vacuum pump.
It also comprises vacuum control check valve, and vacuum control check valve is connected with the intakeport of liquid-ring vacuum pump.
It also comprises suction booster, and suction booster is arranged between the water-supplying mouth of outlet and liquid-ring vacuum pump of heat exchanger.
The advantage of the utility model is:
1. working solution gets in the liquid-ring vacuum pump after gas-liquid separation once more, has realized recycle, can not pollute environment;
2. the organic substance in the working solution is prone to reclaim;
3. be provided with vacuum control check valve, can prevent that the phenomenon of backflowing from appearring in liquid-ring vacuum pump when shutting down.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure, 1-liquid-ring vacuum pump, 2-gas-liquid separator, 3-heat exchanger, 4-vacuum control check valve, 5-suction booster.
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; The liquid-ring vacuum pump closed-loop system; It comprises liquid-ring vacuum pump 1, gas-liquid separator 2 and heat exchanger 3; The drain opening of liquid-ring vacuum pump 1 is connected with the import of gas-liquid separator 2, and the liquid port of gas-liquid separator 2 is connected with the import of heat exchanger 3, and the outlet of heat exchanger 3 is connected with the water-supplying mouth of liquid-ring vacuum pump 1.It also comprises vacuum control check valve 4, and vacuum control check valve 4 is connected with the intakeport of liquid-ring vacuum pump 1.It also comprises suction booster 5, and suction booster 5 is arranged between the water-supplying mouth of outlet and liquid-ring vacuum pump 1 of heat exchanger 3.
Gas is extracted out through liquid-ring vacuum pump 1, and gas mixes the back and gets into gas-liquid separator 2 with working solution, and the gas after the separation is discharged from the relief opening of gas-liquid separator 2, and working solution gets in the liquid-ring vacuum pump 1 after heat exchanger 3 coolings once more.
Claims (3)
1. liquid-ring vacuum pump closed-loop system; It is characterized in that: it comprises liquid-ring vacuum pump (1), gas-liquid separator (2) and heat exchanger (3); The drain opening of liquid-ring vacuum pump (1) is connected with the import of gas-liquid separator (2); The liquid port of gas-liquid separator (2) is connected with the import of heat exchanger (3), and the outlet of heat exchanger (3) is connected with the water-supplying mouth of liquid-ring vacuum pump (1).
2. liquid-ring vacuum pump closed-loop system according to claim 1 is characterized in that: it also comprises vacuum control check valve (4), and vacuum control check valve (4) is connected with the intakeport of liquid-ring vacuum pump (1).
3. liquid-ring vacuum pump closed-loop system according to claim 1 is characterized in that: it also comprises suction booster (5), and suction booster (5) is arranged between the water-supplying mouth of outlet and liquid-ring vacuum pump (1) of heat exchanger (3).
