Description
Technical field
The utility model is related to used oil reclaimer field, specifically, is related to a kind of vacuum distillation apparatus liquid ring vacuum
Pump prime fluid collection device.
Background technology
In domestic and international vacuum distillation apparatus, decompression column overhead pumped vacuum systems typically has three kinds：Vapor pumped vacuum systems,
Liquid ring vacuum pumping system, dry type air-cooled roots vacuum pump system.What wherein application was most is liquid ring vacuum pumping system, generally water
Ring and oil ring, wherein oil ring vacuum pump are higher than water ring vacuum pump due to suction, so being applied in vacuum distillation apparatus
It is the most extensive.
Oil ring vacuum pump operation principle is：Equipped with appropriate oil as working solution in the pump housing, when impeller revolves clockwise
When turning, oil throws to surrounding by impeller, under the action of the centrifugal force, forms the closed circular oil ring of an equal thickness.In the bottom of oil ring
Surface is firm tangent with impeller wheel, and upper inside surface is contacted with blade tip.Now impeller wheel is firm forms a crescent with oil ring
Space, the space is divided into several small chambers equal with lobe numbers by impeller again.When with 0 ° of the bottom of impeller for starting point, impeller
Before rotation at 180 °, the volume of small chamber changes from small to big, and is communicated with the air entry on end face, and now gas is inhaled into, and works as suction
Depressed beam, small chamber then with air entry completely cut off, impeller continue rotate, from large to small, gas is compressed the volume of small chamber, when small chamber with
When exhaust outlet is communicated, gas is just discharged outside pump.Because impeller relative to rotation oil ring is eccentric, oil space between the blades
It is interior to move back and forth, the effect aspirated and compressed is produced to pumped medium.In expiratory phase, oil ring, which is gradually distance from, takes turns firm, will pump
Medium is sucked from air entry vertically, in exhaust phase, and oil ring, which is gradually approached, takes turns firm, and pumped medium is arranged from exhaust outlet vertically
Go out, continuously pumping liquid, just reach the purpose vacuumized.
But during waste oil regeneration utilization, when oil ring vacuum pump is operated, it can usually run into problems with：
Vacuum distillation column overhead is influenceed in gas phase extraction by oil property, and tower top has micro moisture and light
Component organic matter enters in the recycle oil of oil ring vacuum pump, after operation a period of time, and emulsification will occur for oil product and viscosity declines
Situation, cause vacuum to decline, do not reach the requirement normally produced.
Utility model content
To solve the above problems, the utility model, which provides a kind of vacuum distillation apparatus liquid-ring vacuum pump prime liquid, collects dress
Put, the problem of to solve in oil ring vacuum pump running oil emulsion and be rotten.
The utility model is arranged on vacuum distillation apparatus tower top outlet and gone on the pipeline of vavuum pump, including two in sequential series
Liquid point flow container, be provided with zeolite fixed-bed reactor and liquid shield in liquid point flow container.
Liquefied liquid phase ingredient buffering falls into liquid point flow container bottom, liquid shield in gas phase in liquid point flow container
The effect composition that is to prevent to liquefy enter in the recycle oil of vacuum pump set.The gaseous component entered in liquid point flow container,
Vapor and light component organic matter are adsorbed in the presence of zeolite fixed-bed reactor, prevent it from entering following for follow-up vacuum pump set
In ring oil.The effect of prime and rear class two-stage liquid point flow container is set to be effective removal, absorption liquefaction component and light component
Organic matter, every grade of liquid point flow container can absorb in gaseous component 90% liquefaction component and light component organic matter, can make true
The service life of empty pump oil extended more than one month, without changing recycle oil within the period.
Further, the zeolite fixed-bed reactor includes propping bar and pressure grid fixed up and down, and propping bar is located under pressure grid
It is molecular sieve in the middle of side, propping bar and pressure grid.The molecular sieve is preferably spherical silicate or alumionsilicate crystalline, molecular sieve
Spherical granularity is preferably 3-5mm.
Further, the liquid shield is arranged on the downside of zeolite fixed-bed reactor.
Further, vacuum distillation apparatus liquid-ring vacuum pump prime fluid collection device also includes condenser and surge tank,
After the condensed device condensation of oil gas of vacuum distillation apparatus tower top outlet discharge, gas phase enters liquid point flow container, and liquid phase enters buffering
Tank.
Further, liquid point flow container is provided with gas phase entrance, gaseous phase outlet and liquid-phase outlet, prime liquid point flow container
Gas phase entrance is connected to vacuum distillation apparatus tower top outlet, and gaseous phase outlet is communicated to the gas phase entrance of rear class liquid point flow container, after
The gaseous phase outlet of level liquid point flow container is communicated to vavuum pump, and the liquid-phase outlet of liquid point flow container bottom passes through pipeline communication to buffering
Tank.
Compared with prior art, the beneficial effects of the utility model are：The utility model can realize vacuum distillation apparatus
Tower top outlet material gas-liquid separation, macromolecular liquid is entered in surge tank, meanwhile, it is capable to by the vapor in gas phase composition and
Light component organic principle is adsorbed, and then ensure that recycle oil in the purity of vacuum pump assembly recycle oil, extension vacuum pump assembly
In service life, vacuum pump assembly recycle oil can more former use time extend one month, improve vacuum, it is ensured that decompression
The stable operation of distilling apparatus.
