Description
Technical Field
the invention relates to the technical field of pipeline cleaning, in particular to an integrated multi-stage complex pipeline water circulation cleaning system and a method thereof, which can be applied to pipeline cleaning in the fields of radar cooling liquid pipeline circulation systems, chemical engineering, boilers and the like.
Background
taking a certain radar cooling liquid circulation system as an example, dust, ions or other impurities inevitably exist in the large radar cooling liquid pipeline circulation system in the processes of production, manufacturing, assembly, hydrostatic test, location installation and the like, and the cooling liquid used by the radar system has very strict requirements on the cleanliness of the pipeline system and does not allow any ions or impurities, especially chloride ions to exist, because in the chloride ion environment, the 316L stainless steel has the defects of pitting corrosion, crevice corrosion and the like, therefore, the 316L stainless steel pipeline system needs to be cleaned according to certain requirements. Common cleaning methods for 316L stainless steel pipelines are as follows: chemical cleaning (acid cleaning or alkali cleaning), high-pressure water cleaning, ultrasonic cleaning and the like. However, this conventional cleaning method has the following drawbacks:
(1) The chemical cleaning method comprises the following steps: the method can well remove the floating rust, oxides, calcifications, oil stains and inorganic salts on the inner wall of the pipeline, but the residual effusion has the possibility of corroding the inner wall of the pipeline while cleaning the inner wall of a complex pipeline system;
(2) a high-pressure water cleaning method: the method can hardly complete the cleaning of the inner wall of the bend of the pipeline;
(3) an ultrasonic cleaning method: the method needs to put the pipe fitting into a cleaning tank, the size of the cleaning workpiece is limited, and the method is only suitable for cleaning the pipeline with small pipe diameter and small length.
In summary, in the large radar cooling liquid pipeline circulating system, the pipeline system is focused on protecting the pipeline during the production and manufacturing process, and there is no adhesion of impurities such as dirt and calcification, so that direct washing with water is also a good cleaning method, but this method not only wastes water resources, but also has the possibility that the highest point of each pipeline branch in the pipeline system cannot be cleaned, and therefore, it is urgently needed to provide a novel cleaning system and method for removing dust, ions or other impurities in a multi-stage and complex pipeline system.
