Abstract
The utility model discloses a reduced pressure distillation vacuum pump unit. The reduced pressure distillation vacuum pump unit is formed by a first roots pump, a second roots pump and a vertical oil-free vacuum pump which are connected in series through pipelines, wherein, a condenser is arranged in front of the vertical oil-free vacuum pump; a pipeline is connected to a vacuum pipeline in the condenser to be connected with a gas-liquid separator; a first valve is arranged on an inlet pipeline of the gas-liquid separator; a second valve is arranged at the bottom of the gas-liquid separator; and a third valve is arranged at the top of the gas-liquid separator. The pressure distillation vacuum pump unit provided by the utility model is provided with the gas-liquid separation device, so that condensable gas in the vacuum pipeline is greatly reduced, the safety operation of the vertical oil-free vacuum pump is guaranteed, the maintenance frequency is reduced, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of vacuum pump unit, especially a kind of decompression distillation vacuum pump unit with gas-liquid separation device.
Background technique
What the vacuum system major part of decompression distillation adopted is the vacuum pump unit.At present, domestic most widely used a kind of vacuum pump unit with higher vacuum is to be made of two Roots pumps and a vertical oil-free vacuum series connection of pumps.Vertical oil-free vacuum pump is air-breathing by piston, compression is discharged gas and finished the work.In the proper functioning cylinder of vertical oil-free vacuum pump should be gas, and a lot of condensable gas are arranged in the middle of the distilled gas, occurs liquid in the middle of compression process in the cylinder, will occur following two aspect problems like this:
1, in the reciprocal compression process of vertical oil-free vacuum pump, the first-class parts of piston, piston rod, cross of the vertical oil-free vacuum pump of liquid meeting impact, and cause these parts damages.
2, liquid can stop up the valve of vertical oil-free vacuum pump on the other hand, accelerates wear of piston-rings.
Generally, the vacuum pump of this described vacuum pump unit will break down behind operation 1-2 time-of-week, has had a strong impact on ordinary production.
The model utility content
In order to address the above problem, the utility model provides a kind of decompression distillation vacuum pump unit with gas-liquid separation device.
The technical solution of the utility model is: a kind of decompression distillation vacuum pump unit is in series by pipeline by first Roots pump, second Roots pump and vertical oil-free vacuum pump, a condenser is set before described vertical oil-free vacuum pump, connect a pipeline on the vacuum pipe in described condenser and link to each other, be provided with on the inlet pipe of this gas-liquid separator that first valve, bottom are provided with second valve, the top is provided with the 3rd valve with gas-liquid separator.
Further, described first valve, second valve and the 3rd valve are the pneumatic valve of fluid level controller and time relay control.
The beneficial effects of the utility model are: a kind of distillation under pressure vacuum pump unit that the utility model provides has gas-liquid separation device, it reduces the condensable gas in the vacuum pipe significantly, guarantee the safe operation of vertical oil-free vacuum pump, reduced maintenance frequency, improved working efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: first Roots pump, 1, the second Roots pump 2, condenser 3, gas-liquid separator 4, the first valves 5, the second valves 6, the three valves 7, vertical oil-free vacuum pump 8, fractionating tower 9.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of decompression distillation vacuum pump unit is in series by pipeline by first Roots pump 1, second Roots pump 2 and vertical oil-free vacuum pump 8, before described vertical oil-free vacuum pump 8, a condenser 3 is set, connect a pipeline on the vacuum pipe in described condenser 3 and link to each other, be provided with on the inlet pipe of this gas-liquid separator 4 that first valve 5, bottom are provided with second valve 6, the top is provided with the 3rd valve 7 with gas-liquid separator 4.
In order to realize the automation of gas-liquid separation control, first valve 5, second valve 6 and the 3rd valve 7 can be set to pneumatic valve by fluid level controller and time relay control.
Distilled gas in the fractionating tower 9 passes through pipeline earlier through first Roots pump 1, through second Roots pump 2, when arriving condenser 3, the condensable gas in the middle of the distilled gas is converted into liquid again, remove the distilled gas of condensable gas and discharge through vertical oil-free vacuum pump 8, condensed fluid then flows into gas-liquid separator 4.After the liquid level in the gas-liquid separator 4 reach a certain height, fluid level controller controls first valve 5 and cuts out, after first valve 5 is closed, second valve 6 controlled by the time relay and the 3rd valve 7 is opened, and begins to emit liquid, after liquid level drops to certain altitude, second valve 6 controlled by fluid level controller and the 3rd valve 7 is closed, after second valve 6 and the 3rd valve 7 were closed, the time relay was controlled first valve 5 and is opened, and gas-liquid separator 4 continues to collect condensed fluids.
