Abstract
The invention discloses a method for treating slurry pipeline blockage. The method comprises the following steps of: 1) closing a main pipeline control valve at the inlet of a main pipeline and a feed pump control valve at the outlet of a feed pump; 2) shutting down a main pump; 3) opening a main pump control valve and opening a blow-off valve at the same time; 4) allowing fluid in a section ranging from a joint point between the outlet of the feed pump and the main pipeline to a point at which the main pipeline enters the main pump to flow towards the atmosphere; and 5) pressurizing the main pipeline by using the main pump of an upstream pump station. In the method, no tool is used, safety problem does not exist, a blocked pipeline does not need replacing and a simple and efficient treatment way is achieved.
Description
Technical field
The invention belongs to the Slurry Pipeline Transportation field, particularly relate to the processing method that a kind of slurry pipeline stops up.
Background technology
In the middle of the course of conveying of slurry pipeline, the method for operation of pipeline has multiple, wherein carries with independent conveying the most common with connecting leg.But under the situation that once independent time of delivery is relatively grown, on the slurry trunk line of main pump inlet, trunk line wearing and tearing valve FV-3015 is to this segment pipe of binding site of feeding pump outlet conduit and trunk line, just formed a hidden danger of stopping up easily, to safe operation formation grave danger of pipeline.
Summary of the invention
The processing method that the object of the present invention is to provide a kind of slurry pipeline to stop up, this mode can solve inlet trunk line blocking problem.
The processing method of a kind of oar body line clogging comprises the steps:
1) the trunk line control valve of trunk line porch and the feeding pump control valve of feeding pump outlet are closed;
2) main pump is shut down;
3) open the main pump control valve, simultaneously blowoff valve is opened;
4) make feeding pump outlet and trunk line binding site to trunk line enter main pump and put fluid in this section directly to atmosphere;
5) utilize the main pump of upstream pumping unit, trunk line is pressurizeed.
Further, after tamper is under pressure, enters main pump point with the trunk line binding site to trunk line by the feeding pump outlet and move.Stopping up material scatters in the process that moves.
The present invention has following beneficial effect:
(1) because the present invention does not use any instrument, there is not any safety problem.
(2) the present invention needn't change blocked pipeline, and pipeline cutting that also will be not blocked is come, so do not need cost substantially.
(3) processing mode is simple, efficient.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Pipeline when Fig. 1 shows slurry and normally carries by feeding pump and the state of valve, when slurry is normally carried, trunk line control valve 2 is in closed condition, feeding pump control valve 6 then is in open mode, and material is directly supplied with main pump by feeding pump control valve 6 and feeding pump outlet with trunk line binding site 4.
As shown in Figure 2; when stopping up the situation of section 3 appearance obstructions; the trunk line control valve 2 of trunk line 1 porch is opened; and the feeding pump control valve 6 of feeding pump outlet closed; main pump 8 is shut down; open main pump control valve 7 then; simultaneously blowoff valve 9 is opened; like this; feeding pump outlet and trunk line binding site 4, trunk line enter main pump point 5, main pump control valve 7, main pump 8 and just form one section path to blowoff valve 9 these segment pipes; ducted water or slurry be just directly to atmosphere, and the tamper that not have bigger pressure to hinder to stop up in the section 3 is mobile.Utilize the main pump of upstream pumping unit, inlet trunk line 1 is pressurizeed, pressure directly is added on the tamper that stops up in the section 3, after tamper is subjected to certain pressure, entering main pump point 5 with trunk line binding site 4 to trunk line by the feeding pump outlet and move, is granular material owing to stop up material, scatters in moving process, get rid of by main pump control valve 7, main pump 8 and blowoff valve 9, to realize cleaning this segment pipe.
