Abstract
The utility model relates to an oil liquid decontaminating device, which solves the problem of enhancing decontaminating performance. An aviation fuel filter which is composed of a cylinder, a end cover, and a drain opening, wherein, a coalescence filter core and a separating filter core are arranged in the cylinder, and the cylinder and the end cover are in a flange combination. The utility model is characterized in that the filter area ratio of the coalescence filter core to the separating filter core is (2.5-3): 1. The utility model can be used for decontaminating aviation fuel.
Description
The utility model relates to fuel oil purification plant.
The Aviation Fuel filter separator has vertical and horizontal two kinds of structures, and they all are used for carrying out the filtration and the dehydration of Aviation Fuel, guarantees the cleannes of Aviation Fuel.The inner barrel of filter separator is equipped with coalescent filter core and separates filter core, and coalescent filter core and the filter area of separating filter core are than being one of key factor that influences its service behaviour.Ratio is excessive, influences the utilization rate of coalescent filter core, and ratio is too small, and influence separates the utilization rate of filter core, and all can influence oil filtration and dehydrating effect under two kinds of situations.In the traditional structure form, coalescent filter core is not optimized than having with the filter area of separating filter core, so matching performance is not good enough.In addition, the problem that discharges water of filter separator fails to solve preferably always.In vertical filter separator, coalescent filter core pedestal also is one of key factor that influences its service behaviour with the relative position that separates between the filter core pedestal.It not only influences the security that oil-out is not brought water into, and the more important thing is and influence the fluidised form of fluid in filter separator, be related to coalescent filter core and separate filter core and whether can make full use of, filter with coalescent whether abundant the problem of fluid flow resistance height.Secondly, separating the through-hole diameter on the filter core center tube wall and distributing also influences the quality of its service behaviour, and it is related to the uniformity that fuel flow rate distributes, and influence is filtered and dehydrating effect.In the traditional structure form, coalescent filter core pedestal and the relative position that separates between the filter core pedestal separate the through-hole diameter on the filter core center tube wall and distribute all existing very big shortcoming.Moreover the end cap of vertical filter separator and cylindrical shell are by flange, screw-nut structural nexus (as shown in Figure 1) together.Generally, the weight of end cap has tens kilograms, and nut has more than 20.When renew cartridge dismounting end cap more, each nut must be backed out from screw, and screw is extracted out from flange hole, manually end cap is moved from cylindrical shell then.Behind the intact filter core to be replaced, said process carries out once again conversely.Whole dismounting process is not only time-consuming but also require great effort.
The purpose of this utility model provides a kind of better performances, easy to operate Aviation Fuel filter separator.
The purpose of this utility model is achieved in that the Aviation Fuel filter separator, it comprises cylindrical shell, end cap, sewage draining exit, coalescent filter core is housed in the cylindrical shell and separates filter core, cylindrical shell is that flange combines with end cap, it is characterized in that: coalescent filter core is (2.5～3) with the filter area ratio that separates filter core: 1.
Above-mentioned design, through test, coalescent filter core reaches best with matching performance between the filter area of separating filter core, has improved the service behaviour of filter separator greatly.
Below by drawings and Examples the utility model is described further again.
Fig. 1 is existing vertical Aviation Fuel filter separator structural representation;
Fig. 2 is the vertical Aviation Fuel filter separator structural representation in the utility model.
As shown in Figure 1: existing vertical Aviation Fuel filter separator, cylindrical shell 4 tops are end cap 5, its flange connects with screw 6, nut 7, coalescent filter core pedestal 2, separation filter core pedestal 9, coalescent filter core 3 is arranged in the cylindrical shell 4 and separate filter core 8, and sewage draining exit 1 is arranged at cylindrical shell 4 bottoms.
As shown in Figure 2: the vertical Aviation Fuel filter separator in the utility model comprises cylindrical shell 14, end cap 16, sewage draining exit 11, coalescent filter core 13, separates filter core 21, coalescent filter core pedestal 12, separates filter core pedestal 22 and connect seal, cylindrical shell 14 combines for flange with end cap 16, wherein, coalescent filter core 13 is (2.5～3) with separating filter core 21 filter areas ratio: 1.For horizontal Aviation Fuel filter separator, its coalescent filter core also is (2.5～3) with separating filter element filtering area ratio: 1.
Wherein, filter separator is vertical, and the pedestal that separates filter core 21 is higher than the pedestal of coalescent filter core 13, and the difference in height F of the two is (15～30) % of coalescent filter core 13 length.Because in filter separator, the pedestal that separates filter core is higher than the pedestal of coalescent filter core, difference in height between the two is coalescent filter core length (15～30) %, it has improved the uniformity of filter core length direction, has reduced the flow resistance of fluid, the service life of having improved filter core.
Wherein, filter separator is vertical, and the through-hole diameter that separates on filter core 21 center tube wall increases from bottom to top gradually, and via area also increases from bottom to top gradually, so that coalescent filter core improves and filters and dehydrating effect with to separate the velocity flow profile of cartridge surface by fuel oil even.
Wherein, filter separator is vertical, and cylindrical shell 14 bottoms are provided with liquid level display unit 23.The bottom of horizontal Aviation Fuel filter separator also is provided with the liquid level display unit.Because filter separator need often discharge water, but when discharge water and the length of discharge time is difficult to control.The utility model has been installed liquid level display unit 23 in filter separator cylindrical shell 14 bottoms, operating personnel are easy to judge the height of water level, both avoided water level too high and oil-out be there are flowing out, avoided discharge time long and fluid is emitted from the dewatering outlet again, make the work of discharging water promptly and accurately, avoided blindness.
Wherein, filter separator is vertical, and cylindrical shell 14 is provided with eyelet bolt 15 with the binding site of end cap 16, and by eyelet bolt 15 cylindrical shell 14 and end cap 16 is connected together.Cylindrical shell 14 is provided with lifting subassembly with a side of end cap 16, and this lifting subassembly is made up of crank 18, rotating disk 20, connecting rod 19 and push rod 17.
Shell flange and end cap flange connect together by the movable joint nut.More during renew cartridge dismounting end cap, only need each nut is backed out several circles (need not nut is backed out from bolt) from the movable joint nut, the movable joint nut just can screw out from the flange hole of opening.Then, rotate the crank of lifting subassembly, with the push rod jack-up that makes progress, push rod promotes end cap again with end cap jack-up, makes it to rotate around ejector rob axis by the connecting rod on the rotating disk.Like this, being about to end cap removes.Behind the intact filter core to be replaced, said process carries out once conversely.Whole dismounting process not only saves time but also laborsaving, has alleviated labour intensity greatly, has shortened the dismounting time, has improved efficiency.
