Description
Technical field
The utility model belongs to oil for electric power regeneration techniques field, is specifically related to a kind of oil for electric power regeneration filter core and Novel filter cartridge inner core thereof.
Background technology
The steam turbine oil that electric power system power plant uses, fire resistant oil, transformer oil, subsidiary engine are affected by external high temperature, oxidation, moisture etc. often can in running deteriorated going bad occurs with the wet goods oil for electric power, the oil problem that exceeds standard occurs.The oil for electric power regenerating unit is specifically designed to the deteriorated product except the middle generation of deoiling, and its core component is regenerator.In the regenerator adsorbent should be housed, in order to adsorb except the deteriorated product in deoiling.Need the adsorbent that more renews after losing efficacy owing to the deteriorated product in the adsorbent adsorbed oil reaches capacity, change for making things convenient for it, in regenerator, designed the regeneration filter core that adsorbent is housed, thus the regenerator design the most key be the design of regeneration filter core.
Existing regeneration filter core adopts ring-shaped cylinder shape radial-flow type structure.This structure makes oil immerse from the side the regeneration filter core, by adsorbent layer and after being close to the filtration material layer of adsorbent, enters into the oil-collecting oil pipe of inner core inside along the filter opening on the filter core inner core, flows out from the oil pipe bottom again.Wherein, filter core inner core filter screen is wave structure, and evenly punching press has filter opening from top to bottom, arranges and bring two problems in such hole:
First, because the upper and lower end of regeneration filter core and inner core thereof all adopts adhesive and the circular end cap of regeneration filter core to carry out bonding, corrugated inner core filter screen reduces because the particularity of its structure causes its upper and lower end and effective contact area of the circular end cap of regeneration filter core, thereby brings gluing tight, adsorbent easily flows out and leak into oil system from inner core two ends filter opening with oil stream possibility.
The second, the regeneration filter core is configured as ring-shaped cylinder shape radial-flow type structure, and it is vertical when packing regenerator into.As the adsorbent that loads in regenerate filter core urceolus and the inner core cavity is filled unreal or rely on Action of Gravity Field skewness, the bottom sorbent quantity is many, the top sorbent quantity is few situation to occur because factors such as transport, collide with causes adsorbent, the cavity top hollow between filter core urceolus and the inner core of then may occurring regenerating, oil stream by behind the urceolus filter opening without adsorbent, directly along the situation of the discharge of inner core top filter opening, the oily flow short-circuit of appearance.This directly affects oil stream and contacts the weakening adsorption effect with the effective of adsorbent.
The utility model content
For addressing the above problem, the utility model purpose is to provide a kind of oil for electric power regeneration filter core and Novel filter cartridge inner core thereof, prevents sternly not causing adsorbent to leak because filter core inner core upper and lower end is gluing and the problems such as oily flow short-circuit.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of oil for electric power Novel filter cartridge inner core has guiding gutter 1-1 vertically equably at described filter core inner core 1 outer surface, and the not perforate of part along filter core inner core 1 axial two ends to middle part direction 1/3 length, and middle 1/3 length part has filter opening 1-2 equably.
The aperture of described filter opening 1-2 is 4～6mm.
The centre-to-centre spacing of described filter opening 1-2 is 12～15mm.
A kind of oil for electric power regeneration filter core comprises the adsorbent 3 of filling in the cavity of 2 of described oil for electric power Novel filter cartridge inner core 1, the filter core urceolus 2 that is arranged on filter core inner core 1 outside, filter core inner core 1 and filter core urceolus and the filtration material layer 4 between adsorbent 3 and the filter core inner core 1.
Be compared with existing technology, the utlity model has following advantage:
1) the increase oil that keeps filter core inner core corrugated designing institute to bring flows the advantage with the adsorbent contact area.The regeneration filter core inner core filter opening process modification of arranging is adhered to the undulatory structural design of filter core inner core, to improve oil stream and adsorbent contact area, adsorption effect as purpose, does not change the design configuration of filter core inner core, helps to guarantee the regeneration effect of oil stream.After the process modification, the absorption regeneration effect of oil stream and the front indifference of improvement.
2) avoid because of gluing tight, possibility that adsorbent leaks along filter core inner core two ends filter opening.Because the filter core inner core is configured as corrugated, to compare with the circular in configuration of routine, this configuration causes effective contact area of filter core inner core and the circular end cap of filter core upper and lower end to reduce, and can bring thus gluing not tight possibility.If the whole punching press filter openings in inner core filter screen two ends then may cause inside and outside adsorbent in the cavity to leak to the situation of oil system along inner core two ends filter opening.The utility model can farthest reduce this risk, prevents the possibility that adsorbent leaks.
3) avoid oil stream without adsorbent, the direct situation of discharging, occur oily flow short-circuit from filter core inner core top filter opening.Filter core inner core filter opening is arranged and is adopted the mode of the even punching press filter opening of 1/3 length part in the middle part of inner core, can guarantee that oil stream fully contacts with adsorbent after regeneration filter core urceolus filter opening flows into, and finally flow out along filter core inner core middle part filter opening along filter core inner core guiding gutter, avoided from the source that the regeneration filter core urceolus that causes because of self gravitation, because of factors such as filling and inner core cavity upper space hollow, oil stream flow into behind the regeneration filter core urceolus directly along the discharge of filter core inner core top filter opening without adsorbent reactivation, the situation of the oily flow short-circuit of appearance.
