Refer to Fig. 1, it is the structural representation of Roots's Water-ring vacuum device of the present utility model.Described device comprises the first Roots pump 1, the second Roots pump 2, safety check 3, water ring vaccum pump 4, gas-liquid separator 5, condenser 6 and knock out drum 7.
On described the first Roots pump 1, offer suction port 11, this suction port 11 can be connected with external container by pipeline.The second Roots pump 2 is connected with described the first Roots pump 1.In this embodiment, described in the volume ratio of described the second Roots pump 2, the volume of the first Roots pump 1 is little.
Described safety check 3, its one end is connected with one end of described water ring vaccum pump 4 by pipeline, and the other end is connected with knock out drum 7 by pipeline.One end of described water ring vaccum pump 4 is connected with safety check 3 by pipeline, and the other end is connected with gas-liquid separator 5 by pipeline.
Knock out drum 7, its one end is connected with described the second Roots pump 12, and the other end is connected with safety check 3.In the utility model vacuum system, a knock out drum 7 more bigger than the effective volume of gas-liquid separator 5 is installed between safety check 3 and the second Roots pump 2, even if produce suck-back phenomenon, water can only enter knock out drum 7, must not enter in other outside container via the second Roots pump 2, the first Roots pump 1 and suction port 11, and then produce unnecessary trouble and safety problem.
Refer to Fig. 2, it is the structural representation of gas-liquid separator and condenser in Fig. 1.Described gas-liquid separator 5 is connected with water ring vaccum pump 4 by pipeline.This gas-liquid separator 5 has the first inner chamber 51, offers the circulation water intake 52, circulating outlet 53 and grease outlet 54, relief opening 55 and the overflow 56 that are connected with described the first inner chamber 51 on this gas-liquid separator 5.Wherein said circulation water intake 52 is positioned at the top of gas-liquid separator 5, and this circulation water intake 52 is connected with water ring vaccum pump 4 by pipeline; Described circulating outlet 53 is positioned at the bottom of gas-liquid separator 5, this circulating outlet 53 is connected with water ring vaccum pump 4 by pipeline, described circulation water intake 52 and circulating outlet 53 form circuit cycle with water ring vaccum pump 4, and the water of the outflow in gas-liquid separator 5 can be recycled.In this embodiment, on described gas-liquid separator 5, be also provided with entering water temp meter and water-exit temperature meter (not shown), for monitoring the temperature of water of inlet and outlet gas-liquid separator 5.
Described condenser 6 is arranged in the first inner chamber 51 of described gas-liquid separator 5.Described condenser 6 have the second inner chamber 61, with cooling water intake 62, coolant outlet 63 that described the second inner chamber 61 is connected, in described the second inner chamber 61, be provided with the dunnage of condensation tube and described condensation tube.Described cooling water intake 62 is connected with external equipment by pipeline with coolant outlet 63, and from condenser 6, cooling water passes through coolant outlet 63 for external equipment.In this embodiment, the quantity of described dunnage is two, and one of them dunnage 64 is in condenser 6, and another dunnage 65 is the inwalls that extend to described gas-liquid separator 5 in self cooling condenser 6.And in this embodiment, this dunnage 64,65, as oil separating plate, is convenient to continuous separate from profit.In other embodiments, the quantity of this dunnage can be more than two.In the utility model, in order to save limited space, condenser 6 is put into gas-liquid separator 5, not only increased cooling effect, make whole Roots's Water-ring vacuum device compacter.Due to the condensation tube of condenser 6 and the synergy of condensation tube dunnage, make in vacuum distillation, part is not condensed, water-fast organic solvent is separated under the effect of the condenser 6 in gas-liquid separator 5 and dunnage thereof rapidly, and overflows from the overfall 56 on gas-liquid separator 5 tops.
Working principle of the present utility model is as follows: in vacuum distillation process, some organic solvents that are not condensed completely (as toluene, petroleum ether etc.) enter the first Roots pump 1 with incoagulable gas (as air) from suction port 11 and then enter in the second Roots pump 2 compressed further compressed.The incoagulable gas containing organic solvent after two-stage compression is inhaled into water ring vaccum pump 4 through knock out drum 7, after fully mixing, enters in gas-liquid separator 5 and condenser 6 with 10～15 DEG C of water in water ring vaccum pump 4.Incoagulable gas is discharged by relief opening 55 in gas-liquid separator 5.Organic solvent due to the effect of dunnage, is separated waterborne organic solvent in gas-liquid separator 5 and condenser 6, and the divided organic solvent coming overflows from the grease outlet 54 on gas-liquid separator 5 tops, flows into outside oil drum.Water in gas-liquid separator 5 and condenser 6, after condenser 6 is cooling, circulates by discharging to come back in water ring vaccum pump 4 in the circulating outlet 53 of gas-liquid separator 5 bottoms.
Roots's Water-ring vacuum device of the present utility model, is placed on condenser in knockout drum, makes facility compact; Before safety check, increase a knock out drum, can avoid safety check malfunctioning, suddenly have a power failure or the gas-liquid separator that causes of misoperation in water suck-back enter in other containers, guarantee safety; The dunnage of condenser is used as to oil separating plate, is convenient to continuous separate from profit, the utility model handling safety, conserve space, and reduced environmental pollution, save resource.
