A kind of anti-blocking filtration system of petroleum pipeline
Technical field
The present invention relates to the oil transportation field, particularly relate to a kind of anti-blocking filtration system of petroleum pipeline.
Background technology
At present, in the oil field, oil transportation fields such as pipeline initial station (output station), terminal (receiving station) and the petrochemical industry of carrying, oil refining, all need to filter with filter, filter can produce obstruction after having grown service time, the sample deficiency of being got when plugged filter can cause sampling, perhaps the sample composition is inaccurate, and the handing-over both sides are joined under fair, just condition.Therefore, need to clean filter, and it is dirty and tired manually to carry out cleaning, also needs to use a large amount of gasoline and cotton yarn simultaneously on time, has not only wasted energy but also contaminated environment.
Summary of the invention
The anti-blocking filtration system that the purpose of this invention is to provide a kind of petroleum pipeline is filtered and can not produced obstruction, does not also need manually to clean.
For achieving the above object, technical scheme of the present invention is:
A kind of anti-blocking filtration system of petroleum pipeline, link to each other with petroleum pipeline, comprise filter, the magnetic valve group, circulating line, described filter is two, described each filter comprises filter housings and filter screen, described filter screen is arranged in the filter housings, leave the space between described filter screen and the filter housings, described magnetic valve group comprises that two prescriptions are to opposite magnetic valve, described magnetic valve group is arranged between described two filters, a wherein end of described two filters is connected with the magnetic valve group by circulating line respectively, the other end of described two filters is connected with petroleum pipeline by circulating line respectively, a wherein end of described each circulating line that is connected with petroleum pipeline is connected with petroleum pipeline, filter screen is connected with space between the filter housings in the other end and the described filter, a wherein end of described each circulating line that is connected with the magnetic valve group is connected with the magnetic valve group, and the other end is connected with filter screen in the described filter; The anti-blocking filtration system of described petroleum pipeline also comprises computer controller, and described computer controller is connected with the magnetic valve group and controls the break-make of magnetic valve; The lower end of described filter also is provided with blowoff valve, and described blowoff valve is connected with filter housings.
Preferably, blowoff valve of the present invention is the manual blowdown valve.
Therefore compared with prior art, the present invention has following beneficial effect:
The present invention can wash filter in the sampling period, can not produce obstruction when filtering, and does not also need manually to clean, and has both saved the energy and don't contaminated environment.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, does not constitute to improper qualification of the present invention, in the accompanying drawings:
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the schematic diagram of the embodiment of the invention;
Fig. 3 is the structural representation of embodiment of the invention middle filtrator.
The specific embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Be the embodiment of the anti-blocking filtration system of a kind of petroleum pipeline of the present invention as shown in Figure 1 to Figure 3, link to each other with petroleum pipeline 4, comprise filter, magnetic valve group 1, circulating line 2, filter is two (filter 31 and filters 32), each filter comprises filter housings 33 and filter screen 34, filter screen 34 is arranged in the filter housings 33, leave the space between filter screen 34 and the filter housings 33, magnetic valve group 1 comprises that two prescriptions are to opposite magnetic valve (magnetic valve 11, magnetic valve 12, magnetic valve 13, magnetic valve 14), magnetic valve group 1 is arranged between filter 31 and the filter 32, a wherein end of filter 31 and filter 32 is connected with magnetic valve group 1 by circulating line 2 respectively, the other end of filter 31 and filter 32 is connected with petroleum pipeline 4 by circulating line 2 respectively, a wherein end of the circulating line 2 that each is connected with petroleum pipeline 4 is connected with petroleum pipeline 4, filter screen 34 is connected with space between the filter housings 33 in the other end and the filter, a wherein end of the circulating line 2 that each is connected with magnetic valve group 1 is connected with magnetic valve group 1, and the other end is connected with filter screen 34 in the filter; The anti-blocking filtration system of petroleum pipeline also comprises computer controller 5, and computer controller 5 is connected with magnetic valve group 1 and controls the break-make of magnetic valve; The lower end of filter also is provided with blowoff valve 6, and blowoff valve 6 is connected with filter housings 33.
Operation principle is as follows:
After connecting power supply, sampler is started working, computer controller 5 control magnetic valves 11, magnetic valve 12 energisings are opened, magnetic valve 13, magnetic valve 14 outages are closed, crude oil is by petroleum pipeline 4 (filter screen 34 outsides) in circulating line 2 enters filter 31, and crude oil will enter (filter screen 34 inboards) in the filter 32 through magnetic valve 11, magnetic valve 12 along path shown in the dotted line, return petroleum pipeline 4 then, this process is the positive flushing process of present embodiment.
Otherwise, computer controller 5 control magnetic valves 13, magnetic valve 14 energisings are opened, magnetic valve 11, magnetic valve 12 outages are closed, crude oil is by petroleum pipeline 4 (filter screen 34 outsides) in circulating line 2 enters filter 32, crude oil will be along path shown in the solid line, enter (filter screen 34 inboards) in the filter 31 through magnetic valve 13, magnetic valve 14, return petroleum pipeline 4 then.This moment, crude oil rinsed out the impurity in filter screen 34 outsides of filter 31, and return again in the petroleum pipeline 4, this process is the backwash process (signal of telecommunication in the above process provides by computer controller 5) of present embodiment, just can realize anti-blocking filtration and so forth.
In the present embodiment, blowoff valve 6 is the manual blowdown valve, and can effectively avoid too much needs the trouble of dismounting filter because of long-term work causes filter bottom ponding.
