Abstract
The utility model relates to important equipment for filtering oil in the production line of petroleum and ethylene. The equipment comprises a barrel body (8) of a filter, an oil inlet (1) and an oil outlet (5), wherein, the oil inlet (1) and the oil outlet (5) are arranged on both sides of the barrel body. A vent hole (2) and a drain outlet (7) are respectively arranged at the upper part and the bottom end of the barrel body (8). A filtering net which is made of stainless steel is arranged in the barrel body. The utility model is characterized in that the filtering net which is made of stainless steel adopts a double-layer structure. An inner net (9) and an outer net (6) are fixedly connected into one body. A nitrogen gas opening (3) and a steam opening (4) are additionally arranged at the point of the vent hole (2) of the barrel body (8). The utility model has the advantages of enlarged effective filtering area, big flow capacity and high production efficiency. The equipment can clear contamination in the filter.
Description
Putting the sweeping type large flow filter on the utility model is the visual plant that oil filters in the oil ethylene production line.
At existing quench oil, adopt underneath type to purge mode in the fuel oil filter plant, its filter comprises filter cylinder (8), be arranged at oil-in (1), the oil-out (5) of cylindrical shell both sides, top and bottom at cylindrical shell (8) are respectively arranged with drain (2) and sewage draining exit (7), in cylindrical shell, be provided with the stainless steel screen pack, be provided with in the bottom of cylindrical shell and purge mouth.This underneath type purging mode has purging not thorough, and the impurity after being filtered is residual serious, and the cycle of repduction is short, and maintenance frequently reaches defectives such as maintenance cost height.And screen pack adopts individual layer stainless steel screen pack, and its surface roughness is big, is stopped up by impurity easily, not easy cleaning.
At above-mentioned the deficiencies in the prior art, the purpose of this utility model is that the original filter impurity of solution is residual serious, and screen pack stops up easily, and production efficiency is hanged down inferior problem.
The technical solution of the utility model is, as shown in the figure, put the sweeping type large flow filter on being somebody's turn to do and comprise filter cylinder (8), be arranged at oil-in (1), the oil-out (5) of cylindrical shell both sides, top and bottom at cylindrical shell (8) are respectively arranged with drain (2) and sewage draining exit (7), in cylindrical shell, be provided with the stainless steel screen pack, it is characterized in that: the stainless steel screen pack adopts double-decker, Intranet (9) and outer net (6) are connected to one, locate to set up nitrogen mouth (3) and steam port (4) at the drain (2) of cylindrical shell (8), to put on the realization purging mode.Described Intranet (9) and outer net (6) are welded as a whole, and the Intranet pore size filter is less than the outer net pore size filter.The shared mouth of pipe of described drain (2), nitrogen mouth (3) and steam port (4).
Accompanying drawing is a utility model overhead large flow filter structure diagram.
It is one that this filter closes three with drain 2, purging mouthful 4 (steam), nitrogen mouth 3, all places cylindrical shell top.Not only saved equipment investment but also simplified the layout of processing line pipeline, also alleviated container, increased the safety coefficient and the service life of container because the intensity that perforate brought descends.The filter screen pack adopts two-layer order identical stainless (steel) wire beyond count to make, its surface smoothness height, roughness are on impurity such as 0.4～0.8, tar are difficult for adhering to, even there is its adhesive force also to reduce greatly, be very easy to clean out through the high-pressure and high-temperature steam purging.The filtration effective area strengthens, and its flow increases, and has improved production efficiency.
Putting the sweeping type large flow filter on the utility model is to realize like this.Medium enters filter from oil-in 1, and by the filtration of screen pack 6,9, the medium after the filtration is discharged from oil-out 5.When filtering build up of dirt to a certain degree, then close gate valve and oil-out 5 back gate valves before the oil-in 1, drain 2 gate valves, nitrogen mouth 3 gate valves when needing to remove reason.Open steam port 4 gate valves, high temperature and high pressure steam enters filter so, acted on filter core and the container barrel, make dirt liquefaction deliquescing, suppressing down, break away from filter core and drum surface and sinked into container bottom, discharge through sewage draining exit 7, purge through high pressure nitrogen again, can thoroughly remove dirt in the filter.
The overhead large flow filter is according to the freely falling body principle; blowing medium enters from filter top; under crunch and high temperature action; variously be attached to the impurity liquefaction of filter core on tube wall or softening; be divided into granule or liquid; naturally fall into filter bottom, enter dirty jar of storage by sewage draining exit 7.
Claims (3)
1, puts the sweeping type large flow filter on a kind of, comprise filter cylinder (8), be arranged at oil-in (1), the oil-out (5) of cylindrical shell both sides, top and bottom at cylindrical shell (8) are respectively arranged with drain (2) and sewage draining exit (7), in cylindrical shell, be provided with the stainless steel screen pack, it is characterized in that: the stainless steel screen pack adopts double-decker, and Intranet (9) and outer net (6) are connected to one, and locate to set up nitrogen mouth (3) and steam port (4) at the drain (2) of cylindrical shell (8).
2, put the sweeping type large flow filter on according to claim 1, it is characterized in that: described Intranet (9) and outer net (6) are welded as a whole, and the Intranet pore size filter is less than the outer net pore size filter.
3, put the sweeping type large flow filter on according to claim 1, it is characterized in that: the shared mouth of pipe of described drain (2), nitrogen mouth (3) and steam port (4).
