Description
Technical field
A kind of chlorine centrifugal compressor fuel tank belongs to the Equipment Control processing system and improves the field.Be applicable to the chlorine centrifugal compressor of carrying that corrosive gas medium, surrounding environment are relatively more abominable, being prone to corrosive gas in the air, to satisfy the needs that chlorine gas compressor group in the large-scale chlorine industry can keep long-period stable operation.
Background technique
Chlorine centrifugal compressor is that chlorine industry is used for a kind of visual plant to chlorination, and it is a kind of rotating vanes machinery, relies on the high speed rotating of impeller; Make gas receive centrifugal action and produce pressure; Gas is at impeller simultaneously, and the diffusion in the overcurrent element such as Diffuser flows, and gas velocity slows down gradually; Dynamic pressure converts static pressure to, the gas pressure raising of getting back.
Yet but there are many problems in the chlorine centrifugal compressor fuel tank in concrete production operation, have a strong impact on the working life of chlorine centrifugal compressor.Wherein distinct issues are in process of production the most, and the chlorine centrifugal compressor fuel tank is in negative pressure state for a long time.Chlorine centrifugal compressor fuel tank top take over to connect the mist of oil fan, and the mist of oil that produces in the chlorine centrifugal compressor fuel tank is taken away, reduces lubricant oil oil temperature rise in the equipment operation, produces a small amount of mist of oil and leaks and cause the pollution of air in the factory building.Because the chlorine centrifugal compressor fuel tank is airtight casing; Only locate to contact with ambient air in shafting oil envelope (labyrinth seal); Therefore when the mist of oil fan is taken mist of oil away; Meeting taken out the chlorine centrifugal compressor fuel tank and is negative pressure, so ambient atmos will enter into the chlorine centrifugal compressor fuel tank from the shafting oil envelope.Has only 20mm and shafting oil envelope and axle sealing gland spacing are less.When fluctuation appearred in the production system operation, the chlorine or the airborne corrosive gas that leak from the axle sealing gland can be drawn into the chlorine centrifugal compressor fuel tank through the shafting oil envelope, cause lubricant oil contaminated.Sliding bearing because of shafting oil envelope installed inside again, corrosive gas also can cause corrosion to the bearing shell piece after getting into the chlorine centrifugal compressor fuel tank.Cause damage of bearings, shaft vibration raises, the maintenance of being forced to stop production of chlorine gas compressor group.Because of the stop production to overhaul of chlorine centrifugal compressor in the unit, will force chlorine gas compressor group even whole production line stop production to overhaul in the large-scale industrial production, can not reach in the large-scale industrial production the requirement of chlorine gas compressor group leader cycle quantity-produced.
Press for the defective that the chlorine centrifugal compressor fuel tank is existed at present and carry out architecture advances, to satisfy the needs that chlorine gas compressor group in the large-scale chlorine industry can keep long-period stable operation.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, a kind of chlorine centrifugal compressor fuel tank that the chlorine gas compressor group is reached need not frequent stop production to overhaul of can long period producing continuously is provided.
The utility model solves the technological scheme that its technical problem adopted: this a kind of chlorine centrifugal compressor fuel tank; Comprise fuel tank main body, mist of oil fan, bearing shell, shafting oil envelope and axle sealing gland; It is characterized in that: the evacuation port place is provided with one and seals cover above shafting oil envelope and axle sealing gland, seals cover and is connected the inlet of mist of oil fan through pipeline, and a side of fuel tank main body is provided with external nitrogen tube; Opposite side is provided with the oil-collecting discharge pipe, is filled with nitrogen in the fuel tank main body.
The described cover that seals places the evacuation port place, top of shafting oil envelope and axle sealing gland, and leaves the gap for tabular.
Described oil-collecting discharge pipe is connected the below of shafting oil envelope and axle sealing gland, and the place is relative with evacuation port, and highly is higher than external nitrogen tube.
Negative pressure can be changed into malleation in the fuel tank main body.The bottom perforate of shafting oil envelope connects the oil-collecting discharge pipe, reclaims the oil droplet that the oil-collecting discharge pipe is discharged.Shafting oil envelope and the mist of oil that axle sealing gland place discharges can be discharged to outside the factory building through the mist of oil fan.
Working principle:
1, through external nitrogen tube nitrogen is charged in the fuel tank main body, make in the fuel tank to become malleation, stop extraneous harmful gas and get into fuel tank, reduce lubricant oil and bearing shell and polluted the problem of corrosion, improve the operation period of compressor by extraneous corrosive gas by negative pressure.
2, owing to be malleation in the bearing housing; Mist of oil can be discharged from the shafting oil envelope; Take to seal cover at the shafting oil portion of sealing up at evacuation port place, chlorine gas compressor top dress, this seals cover and is connected to the inlet of mist of oil fan through pipeline, through the mist of oil fan mist of oil that shafting oil envelope place discharges is transported to outside the factory building; Carry out environmental protection treatment, thereby solved the pollution problem of mist of oil in the factory building.
3, the bottom perforate is connected an oil-collecting discharge pipe with the axle sealing gland in the shafting oil envelope, and mist of oil is formed oil droplet from the discharge of oil-collecting discharge pipe, and the oil droplet that the oil-collecting discharge pipe is discharged reclaims.
Compared with prior art; The beneficial effect that the chlorine centrifugal compressor fuel tank of the utility model is had is: the utility model is with replenishing nitrogen in the fuel tank; Nitrogen neither changes fuel tank inner fluid performance as a kind of inert gas, can stop extraneous harmful gas simultaneously again and get into fuel tank; Reduce lubricant oil and bearing shell and polluted the problem of corrosion, the operation period of chlorine gas compressor group is significantly improved by extraneous corrosive gas.The long periods of time in order of chlorine gas compressor group is 12 months before transforming, and transforms back chlorine gas compressor group continuous operation period 36-60 month, does not need stop production to overhaul.This structure preferably resolves chlorine centrifugal compressor tank lubrication oil and is prone to the rotten problem of contaminated generation, and the oil droplet that condenses is reclaimed the waste that both can reduce resource, and this has improved the shopwork environment again.
