Abstract
The utility model relates to a vacuum extractor. The existing steam jet vacuum pump has the disadvantages of more steam consumption quantity and requirement to be arranged at a high position, and the vacuum degree of water ring vacuum pump can not satisfy the technical requirement. The steam outlet opening of the steam injector according to the utility model is communicated with the steam inlet opening of the pipe bundle condenser. The steam outlet and liquid outlet opening of the pipe bundle condenser are communicated with the steam extraction opening of the water ring vacuum pump through the pipeline. The steam extraction opening of the steam injector is connected with the technical pipeline. The steam outlet opening of the water ring vacuum pump is communicated with the steam inlet opening of the steam-liquid separator. The technical end gas is evacuated by the steam outlet opening of the steam-liquid separator. The utility model has a majority of advantages of the steam jet vacuum pump and the water ring vacuum pump. At the same time the steam consumption quantity of the whole vacuum apparatus is reduced, and the vacuum extractor can be installed at any height.
Description
Technical field
The utility model belongs to the industrial technology field, specifically relates to a kind of vacuum pumping device.
Background technique
Existing vacuum pumping device adopts steam ejection vacuum pump or water ring vaccum pump more in the industry.Steam consumption is bigger when adopting steam ejection vacuum pump, and is higher to the quality requirements of steam, needs high-order the layout simultaneously, causes the factory building cost than higher.If the employing water ring vaccum pump, then degree of vacuum can't satisfy technological requirement mostly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of steam consumption is low, degree of vacuum is high, does not need the high-order vacuum pumping device of arranging simultaneously.
The utility model comprises steam jet device, pipe bundle condenser and water ring vaccum pump.The steam-expelling port of steam jet device is communicated with the steam inlet of pipe bundle condenser, and the steam discharge liquid port of pipe bundle condenser and the extraction opening of water ring vaccum pump pass through pipeline connection.The extraction opening of steam jet device connects process pipeline, and the steam-expelling port of water ring vaccum pump is communicated with the steam inlet of vapor-liquid separator.Process tail gas is by the relief opening emptying of vapor-liquid separator.
Steam jet device, pipe bundle condenser, water ring vaccum pump and vapor-liquid separator in the utility model adopt existing matured product, and inventive point of the present utility model is to realize goal of the invention of the present utility model by the connection of above each device.
Steam ejection vacuum pump generally is made up of single or multiple steam jet ejector series connection intercondensers, and working vacuum degree scope is very wide, and rate of air sucked in required is very big, is not had strict demand to taking out medium, is not afraid of the pollution of being taken out medium.No matter taken out the temperature height of medium, no matter also have or not dust impurity and corrosivity to use.The effect of condenser mainly is to be used for coagulated steam in condensation working steam and the pumped gas, to reduce the load of bleeding of subordinate's jet pump.Condenser must be installed on the scaoffold of fluid-tight face more than 11 meters, makes condensed fluid have enough liquid-column heights to overcome pressure difference and enters water (liquid) envelope pond (case) smoothly.Steam ejection vacuum pump is owing to adopt water vapor as working medium, and is higher to the quality requirements of water vapor, final stage sparger particularly, and vapor pressure can cause the fluctuation up and down of degree of vacuum when unstable or moisture, sometimes even can not take out vacuum.Taking out the big occasion of fixed gas amount, the working steam consumption of final stage sparger is bigger.Water ring vaccum pump is mainly used in coarse vacuum and bleeds, simple in structure, easy to manufacture, reliable operation, easy to use, durability is strong, can take out corrosive gas, contain the gas and the air-water mixture of dust.This vacuum pumping device adopts steam jet device, pipe bundle condenser and water ring vaccum pump series connection form, has inherited most of advantage of steam ejection vacuum pump and water ring vaccum pump.The steam jet device makes that as the suction booster of water ring vaccum pump this vacuum device can be in the work of high vacuum occasion.Condenser reduces the load of bleeding of water ring vaccum pump with the working steam of sparger and the coagulated vapor condensation in the pumped gas.Water ring vaccum pump is extracted fixed gas, the uncooled condensed fluid that coagulates in steam and the condenser of part in the pumped gas out emptying as the final stage sparger in the fore pump replacement steam ejection vacuum pump.Water ring vaccum pump is directly extracted the condensed fluid in the condenser out, and condensed fluid does not need enough liquid-column heights and overcomes pressure difference, thereby the utility model can be installed in arbitrary height.Water ring vaccum pump replaces the final stage sparger, has significantly reduced the steam consumption of whole vacuum system, and can be used for the unstable and moisture higher occasion of vapor pressure.

Embodiment
As shown in Figure 1, a kind of vacuum pumping device comprises steam jet device 3, pipe bundle condenser 6 and water ring vaccum pump 12.The steam-expelling port 4 of steam jet device 3 is communicated with the steam inlet 5 of pipe bundle condenser 6, and the steam discharge liquid port 15 of pipe bundle condenser 6 is communicated with by pipeline 14 with the extraction opening 13 of water ring vaccum pump 12.The extraction opening 2 of steam jet device 3 connects process pipeline, and the steam-expelling port 11 of water ring vaccum pump 12 is communicated with the steam inlet 10 of vapor-liquid separator 8.Fixed gas in the process tail gas is by relief opening 7 emptyings on vapor-liquid separator 8 tops, and condensed fluid is discharged by the flow-off 9 of vapor-liquid separator 8 sidewalls.
When working steam enters with certain pressure and the flow steam inlet 1 by steam jet device 3, behind Laval nozzle, pressure descends.Enter steam jet device 3 from the process gas of process pipeline by the extraction opening 2 of steam jet device 3, the Venturi tube that working steam enters steam jet device 3 with supersonic speed injection process gas, in Venturi tube, carry out energy interchange, and mix compression, directly be discharged to pipe bundle condenser 6 with certain pressure.Cooling water is entered by the water intake 16 of pipe bundle condenser 6, is discharged by water outlet 17.In pipe bundle condenser 6, process gas and working steam and cooling water indirect heat exchange, but major part condensing body is condensed.Uncooled gas and condensed fluid are taken away by water ring vaccum pump 12 simultaneously by the steam discharge liquid port 15 of pipe bundle condenser.Uncooled gas enters vapor-liquid separator 8 after aspirating superchargings through water ring vaccum pump 12, carries out discharging after the vapor-liquid separation.
Claims (1)
1, a kind of vacuum pumping device, comprise steam jet device, pipe bundle condenser and water ring vaccum pump, the steam-expelling port that it is characterized in that the steam jet device is communicated with the steam inlet of pipe bundle condenser, the steam discharge liquid port of pipe bundle condenser and the extraction opening of water ring vaccum pump are by pipeline connection, and the steam-expelling port of water ring vaccum pump is communicated with the steam inlet of vapor-liquid separator.
