Abstract
The utility model relates to a coalescence filter core. The utility model is provided with a cylindrical inner framework and a cylindrical outer framework, wherein both ends of the framework are provided with end rings and one side of the center of the inner framework is provided with a polyester filter layer. An emulsion breaking layer is arranged between the inner framework and the outer framework. The outside of the outer framework is orderly provided with a coalescence layer and a discharge layer. The utility model has the advantage that the coalescence is layered, the micro oil droplets are gradually increased and thus the oil removal ability of the filter core is improved.
Description
Technical field
The utility model relates to a kind of coalescent filter core, and this coalescent filter core adopts international advanced special coalescence material to make, and can remove oil and hydrocarbons in the various oil-polluted waters up hill and dale.
Background technology
Chinese patent 95224596 discloses a kind of filter separator of oil plant medium, is made up of tank-like shell, coalescent filter core, end socket, blowoff valve, air bleeding valve etc.Housing is a cylindrical tank, end socket above is tightly connected, Pressure gauge and air bleeding valve are equipped with in the end socket upper end, and blowoff valve is positioned at lower housing portion, and housing central authorities are fixed with the coalescent filter core with breakdown of emulsion layer and coalescent layer that multilayer material is made, oil plant enters filter core by oil inlet pipe, solid impurity is wherein filtered by the innermost layer of filter core, and oil plant sees through filter core and flows to outside the filter body, by the oil and water displacement effect, the coalescent gradually change of small water droplet in the oil is big and at the bottom of being deposited on jar, oil plant is cleaned.This apparatus structure is simple, practical, easy to operate, has very high practical value.But the demulsification of this patent and coalescent effect are relatively poor, can't thoroughly remove oil and hydrocarbons in the oil-polluted water.Therefore, need to propose a kind of new coalescent filter core.
Summary of the invention
The purpose of this utility model is to provide a kind of coalescent filter core, and this coalescent filter core adopts multiple coalescence material, and layering is coalescent, and small oil droplet is increased gradually, can remove oil and hydrocarbons in the various oil-polluted waters up hill and dale.
The purpose of this utility model is realized by following technical proposals: a kind of coalescent filter core, a cylindric inner framework is arranged, with a cylindric outer skeleton, the skeleton two ends are provided with end ring, its main points are: described inner framework center one side is provided with the polyester filter course, be provided with the breakdown of emulsion layer between described inner framework and the outer skeleton, the outside of described outer skeleton is provided with coalescent layer, drain layer in proper order.
Compared with the prior art the utility model has following advantage:
1, coalescence material of the present utility model is a composite construction, adopts layering coalescent, thus the oil removing ability that small oil droplet is increased gradually improve filter core greatly.
2, it is fixed that coalescence material of the present utility model adopts special-purpose resin and technology, even also short circuit or fibre shedding can not occur under high flow rate and strong pressure pulsatile impact.
3, the two ends of material for core of the present utility model adopt the oil resistant water-resistant adhesive to handle, and are connected firmly, seal reliable.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples
Fig. 1 is structural representation of the present utility model (partial sectional view)
Fig. 2 is partial enlarged drawing of the present utility model (Figure 1A place enlarged drawing)
Fig. 3 is a fundamental diagram of the present utility model
The specific embodiment
Referring to Fig. 1, Fig. 2, coalescent filter core 1 of the present utility model, a cylindric inner framework 3 is arranged, with a cylindric outer skeleton 6, this skeleton adopts stainless steel material to make, it can be mesh skeleton, it also can be the skeleton of an orifice-plate type, these skeleton two ends are provided with the end ring 2 of stainless steel material, this end ring is an annular groove shape, described inner framework center one side is provided with polyester filter course 4, is provided with breakdown of emulsion layer 5 between described inner framework and the outer skeleton, and the outside of described outer skeleton is to be provided with coalescent layer 7, drain layer 8 from inside to outside in proper order.In the present embodiment, described breakdown of emulsion layer is the cylindric glass fiber paper layer of 5-20 micron for filtering accuracy, and described coalescent layer is cylindric polyester foamed material or gum sprayed cotton material, and described drain layer is cylindric polypropylene filter paper layer.Two terminations of described polyester filter course, breakdown of emulsion layer, coalescent layer, drain layer all adopt oil resistant water-resistant adhesive and end ring position bonding, can guarantee to be connected firmly, seal reliably.
Referring to Fig. 3, oil-polluted water outwards flows from coalescent filter core center, and this filter core has special micro-filtration, breakdown of emulsion and coalescent oil content multi-efficiency.Coalescent filter core by the high accuracy micro-filtration, is effectively tackled the granule foreign in the water on the one hand, especially tackles greasy filth impurity such as the tangible iron oxide of stable emulsion state, iron sulfide, helps follow-up breakdown of emulsion and coalescent function.Breakdown of emulsion and coalescent effect are by special material extremely strong affinity of oily substance and hydrophobicity to be realized on the other hand, and coalescent filter core comes out small, free oil content in the water is coalescent, and are big oil droplet in its surface condensation.Realize removing up hill and dale the oil in the oil-polluted water and the purpose of hydrocarbons.
Claims (2)
