Description
Technical Field
The invention relates to the technical field of liquid filtration and purification, in particular to a liquid hydrocarbon filtration separator with high energy efficiency.

The liquid hydrocarbon filtering separator can also be used for separating caustic alkali, amine and acid from various liquid hydrocarbons such as petrochemical products (gasoline, diesel oil and lubricating oil), liquefied petroleum gas and the like.
The coalescing filter element is a core functional component of the liquid hydrocarbon filtering separator, and the surface flow velocity of the coalescing filter element has very obvious influence on the coalescing effect of the coalescing filter element and the dehydration performance of the filtering separator.

It is also evident from fig. 2 and 4 that the distribution of coalescing filter elements is non-uniform along the length. The flow rate is greater near the inlet end and is less at the end farther from the inlet. I.e., the flow rate of the coalescing filter element near the inlet end in the near-mouth region L1 is greater than the optimal economic flow rate (average design flow rate), and the flow rate of the coalescing filter element far from the inlet end in the far-mouth region L2 is less than the optimal economic flow rate (average design flow rate).

Referring to fig. 5 to 8, fig. 5 is a schematic structural diagram of an embodiment of a liquid hydrocarbon filtering separator with high energy efficiency according to the present invention; FIG. 6 is a schematic view of the flow equalization tube and coalescing filter element of FIG. 5; FIG. 7 is a schematic diagram of an embodiment of the flow equalizer of FIG. 6; FIG. 8 is a flow profile of coalescing filter element fluid with a flow equalization tube installed.
In a specific embodiment, the invention provides a liquid hydrocarbon filtering separator with high energy efficiency, which comprises a coalescing filter element 3, materials to be filtered enter the coalescing filter element 3 from the end and flow out from the side wall, and a flow equalizing component is arranged in the coalescing filter element 3, so that the flow equalizing component ensures that the flow out speed of the materials to be filtered along the length direction of the coalescing filter element 3 is uniform.
The liquid hydrocarbon filtering separator comprises a barrel body 1, a liquid hydrocarbon filtering separator body and a liquid hydrocarbon filtering separator body, wherein the liquid hydrocarbon filtering separator body comprises a coalescence filter element assembly and a separation filter element assembly, the coalescence filter element assembly comprises a coalescence filter element 3, a flow equalizing component and a coalescence filter element tray 2, a feed inlet of the coalescence filter element tray 2 is communicated with an inlet pipeline, and a plurality of coalescence filter elements 3 are respectively arranged at a plurality of discharge outlets of the coalescence filter element tray 2; the separation cartridge assembly comprises a separation cartridge 5 and a separation cartridge tray 6.
The flow equalizing component is a flow equalizing pipe 4, and the flow equalizing pipe 4 is arranged in the coalescing filter element 3 and is arranged on the coalescing filter element tray 2; the surface of the flow equalizing pipe 4 is provided with a plurality of through holes 41, and the opening area of the through holes 41 is gradually increased from the inlet end of the flow equalizing pipe 4 to the tail end direction of the flow equalizing pipe 4;
When the liquid hydrocarbon filtering separator works, liquid hydrocarbon mixed with water and/or solid particles enters through an inlet pipeline of the liquid hydrocarbon filtering separator, firstly enters into the coalescing filter element 3, and filters the solid particles from the inner surface of the coalescing filter element 3 to the outer surface; then, after passing through the demulsification layer and the coalescence layer in the coalescence filter element 3, the water in the liquid hydrocarbon is coalesced, so that small liquid drops are coalesced into large liquid drops, and the large liquid drops fall off and settle from the surface of the coalescence filter element. And finally, carrying large water drops to the separation filter element, wherein the water drops are blocked by the separation filter element assembly and separated from the liquid hydrocarbon, so that the clean liquid hydrocarbon is finally obtained.
It has been found that in the prior art liquid hydrocarbons to be filtered flow from the inside to the outside of the coalescing filter cartridge 3 as they pass through the inlet conduit into the coalescing filter cartridge tray 2 and then into the coalescing filter cartridge 3, and coalesce through the coalescing filter cartridge 3. Liquid hydrocarbon enters the inside of the coalescing filter element 3 from the inlet end of the coalescing filter element 3, and continuously flows from the inside of the coalescing filter element 3 to the outside of the coalescing filter element 3 in the process of flowing towards the tail end of the coalescing filter element 3 along the axial direction of the coalescing filter element 3, so that the filtration of solid particles and the coalescence and separation of water are realized.
Conventional liquid hydrocarbon filter separators are flow engineered based on the average surface flow rate of the coalescing filter element, but in practice the flow rate distribution is non-uniform across the length of the coalescing filter element. The flow rate is greater near the inlet end and is less at the end farther from the inlet. I.e., the flow rate of the coalescing filter element near the inlet end in the near-mouth region L1 is greater than the optimal economic flow rate (average design flow rate), and the flow rate of the coalescing filter element far from the inlet end in the far-mouth region L2 is less than the optimal economic flow rate (average design flow rate). The large flow rate of the near-mouth area L1 of the coalescing filter element can reduce the coalescing effect, and the small flow rate of the far-mouth area L2 can cause the problems of waste of filtering dewatering capacity and low energy efficiency.

In the solution according to the application, a flow equalization pipe 4 is provided inside the coalescing filter element 3, the flow equalization pipe 4 being provided with a plurality of through holes 41, as shown in figures 6 and 7.

When liquid hydrocarbon flows from the inlet end of the flow equalizing pipe 4 to the tail end along the axial direction, the flow velocity of the liquid hydrocarbon gradually decreases; meanwhile, the opening area of the through hole 41 of the flow equalizing pipe 4 gradually increases in the direction from the inlet end to the tip end; the variation in the flow rate of the liquid hydrocarbon is equalized by the variation in the opening area of the through-hole 41 of the flow equalizing pipe 4.
Near the inlet end, the liquid hydrocarbon flow rate is larger, the opening area of the through hole 41 of the flow equalizing pipe 4 is smaller, and a certain limit can be made on the higher flow rate; near the tail end, the liquid hydrocarbon flow rate is smaller, the opening area of the through hole 41 of the flow equalizing pipe 4 is larger, and the limitation on the flow rate is smaller; the flow rates of the coalescing filter element 3 in the length direction tend to be the same through the flow equalizing effect of the flow equalizing pipe 4, as shown in fig. 8, so that the adverse effect on the coalescing performance caused by the overlarge flow rate of the lower part of the coalescing filter element 3 is eliminated, and the surface flow rate of the coalescing filter element is improved. And simultaneously improves the dehydration performance of the filtering separator.

The through hole 41 may be a circular hole or may be a hole of another shape. When the through hole 41 is a circular hole, the change in the opening area is achieved by the change in the aperture. In addition to the variation in the opening area of the through-holes 41, the flow velocity of the liquid hydrocarbon can be equalized by the density distribution of the through-holes 41.
In a second specific embodiment, the flow equalizing component is a flow equalizing pipe 4, a plurality of through holes 41 are formed on the surface of the flow equalizing pipe 4, and the aperture of each through hole 41 is gradually increased from the inlet end of the flow equalizing pipe 4 to the end direction of the flow equalizing pipe 4.
Specifically, in the direction from the inlet end to the end, the variation of the opening aperture of the through-hole 41 and the density of the through-hole 41 are set according to a certain rule according to the variation of the flow velocity of the liquid hydrocarbon inside the coalescing filter element 3 during use.
In a third specific embodiment, the flow equalizing component is a flow equalizing pipe 4, a plurality of through holes 41 are formed on the surface of the flow equalizing pipe 4, the opening area of the through holes 41 is gradually increased from the inlet end of the flow equalizing pipe 4 to the end direction of the flow equalizing pipe 4, and the density of the through holes 41 is increased from sparse to dense.
