Description
Technical field
The utility model belongs to the vacuum separation technical field, is specifically related to a kind ofly under vacuum state, eliminates the oily-water seperating equipment of bubble by self-excited vibration.
Background technology
In insulating oil, how many water content determines the breakdown voltage height of insulating oil, and the insulation status of oil-filled transformer is the principal element that determines its safe and stable operation.In the transformer long-play, play insulation progressively aging under the effect of electric field, moisture, oxygen, temperature and mechanical force, lost efficacy finally and cause transformer life to stop.In the process of Transformer Insulation Aging, cellulose is heated, the oxidative degradation meeting produces moisture, and moisture is the catalyst of cellulose oxidation reaction, in the degraded of accelerating fibers element, self does not consume, and that is to say, when moisture dissociates out from insulation, to further promote cellulosic degraded, the degree of polymerization of insulating board is reduced, and then cause the tensile strength of insulating board to reduce.After insulating board made moist, its electric strength will descend, and dielectric dissipation factor increases, and the starting voltage of shelf depreciation and screen discharge will reduce, and made more easily development of screen discharge.
Show by research, in insulating board water content be 2% aging speed be initial water content 0.3% 6-16 doubly, in the ageing rate of insulating board and insulating board, water content roughly is directly proportional.The high-power transformer of applying in domestic power system simultaneously is oil-filled transformer, its internal transformer oil and some solid insulating materials due to be subjected to the each side factor affect meeting gradually aging, decompose, produce a small amount of gases such as hydrogen, hydrocarbon gas, carbon monoxide and carbon dioxide, and major part is dissolved in oil.When transformer inside existed latency fault or fault aggravation, in oil, amount of gas can increase accordingly.In general oil, failure gas itself can't hinder the safe operation of equipment, but gas content of oil when too high electric property to oil can have a certain impact, can produce the danger such as blast when hydrogen, when hydrocarbon gas is excessive.
Vacuum separation still for not vibrating froth breaking mainly has the following disadvantages:
1, in through knockout tower, isolating the process of water content in oil, there is a large amount of fluid to inject the vacuum separation chamber, when knockout tower flows downward; often can produce a large amount of steam bubbles; if these bubbles are vanished, portion gas just is not separated, and causes separation insufficient.
2, the existence of a large amount of steam bubbles makes from peephole and is difficult for observing real oil level, also easily produces the oil spout situation and affects ability to work and the service life of vavuum pump.
When the fluid that 3, contains a large amount of steam bubbles is flowed through gear oil pump, can increase the operation of oil pump noise, its condition of work is worsened and directly affect vacuum oil-filter and separate the effect of W/O.
In order effectively to impel Oil-gas Separation, most of vacuum separation stills are all additional vibratory equipment, can improve separating effect, but the vacuum separation still of these additional vibrator froth breakings, still Shortcomings part:
If 1 installs a plurality of electric vibrators, the vacuum separation still need to be made into openable version, and this makes device structure complicated, and bulky, the device fabrication cost is high.
2, need electric energy or other energy to drive, energy consumption is higher.
3, electric vibrator needs electric elements to control, and controls complexity, and the equipment use cost is high.
Summary of the invention
For overcoming equipment cost and the high defect of energy consumption that exists in prior art, the utility model provides a kind of self-excited vibration froth breaking separating still simple in structure, this device need not additional vibrator and electric elements, greatly reduce device fabrication cost and energy consumption cost, and the while is froth breaking fast, and Oil-gas Separation is abundant.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of self-excited vibration froth breaking vacuum separation still, comprise vacuum separation still tank body, be provided with oil-in at vacuum separation still tank body top, sidepiece is provided with vacuum pumping opening, and bottom is provided with oil-out and check-valves, and vacuum separation still tank body top is provided with the spray chamber corresponding to oil-in, the spray chamber bottom is provided with the nozzle of some Jet with downward flow directions, be provided with knockout tower below nozzle, this knockout tower bottom is connected with vacuum separation still inner tank wall elasticity by flexible connection piece, and described knockout tower is built-in with separate mesh.
Adopt the self-excited vibration froth breaking vacuum separation still of technique scheme, by spray chamber with oily even spraying on the separate mesh of knockout tower, because the shower nozzle spraying has certain pressure, order about knockout tower and produce self-excited vibration, make collision or bubble and the interior separate mesh collision of knockout tower mutually between bubble, bubble is because the effect generation of external force is broken, and gas breaks away from the encirclement of oil film, discharges by vacuum pumping opening finally.
In order to impel Oil-gas Separation, described stainless steel wire separate mesh is provided with two-layer and level is built in knockout tower, and bubble is repeatedly collided with separate mesh, accelerates bubble and breaks, and gas breaks away from oil film.
Preferably, described flexible connection piece is spring, because spring is compared the more simple actual effect of other flexible connection pieces, good vibrating effect is arranged.
The utility model volume is little, simple in structure, need not additional vibrator, utilize the driving force of oil feeding system to order about knockout tower self-excited vibration, reduced the device fabrication cost, knockout tower, without appliance components such as motors, further reduces energy consumption simultaneously, reduce use cost, this self-excited vibration froth breaking vacuum separation still froth breaking is rapid, and the dehydration degassing efficiency is high, and gas-liquid separation is abundant.
