Method and equipment for cleaning pipeline

Abstract

The invention discloses a method for cleaning a pipeline. Ice slurry is adopted as a cleaning medium and is driven through a volumetric pump to move inside the pipeline when the pipeline is cleaned, and the ice content rate of the ice slurry is 10-50%. The invention further discloses equipment for cleaning the pipeline by the adoption of the method. The ice slurry is driven through the volumetric pump to move inside the pipeline so as to clean the pipeline and flush dirt residues, while the water solution is utilized for cleaning the pipeline, the shear force of movement of the ice slurry is utilized for removing the dirt residues in the pipeline to achieve the flushing function, cleaning and flushing are finished at a time, water consumption can be reduced, cleaning cost is lowered, water is saved, and environment is protected; the freezing point of the ice slurry is lowered through additives, the evenness of the ice slurry is improved, and compared with an existing ice making method using the ice making solution of the same concentration, the method has the advantages that the ice slurry with higher ice content rate and better evenness can be made, and the making cost of the ice slurry can be lowered.

Description

technical field [0001] The invention belongs to the technical field of pipeline cleaning, in particular to a pipeline cleaning method and equipment. Background technique [0002] At present, the pipeline cleaning methods in the food industry include chemical cleaning, high-pressure water cleaning and PIG pigging. Chemical cleaning is to temporarily transform the pipeline by adding chemical agents; high-pressure water cleaning is to promote the movement of water through high pressure; PIG pigging is to use pump power to drive PIG (pipe pig) to push forward in the pipeline. , mainly used for descaling inside the pipe. [0003] Patent document CN103075912A, on January 28, 2013, disclosed a cleaning method for floor heating pipes, which is characterized in that the first flushing removes the slime, and then soaks the pipes with cleaning solution to dissolve the rust and scale in the pipes, and finally Perform a second flush on the pipes. In this patent application, there are ...

Problems solved by technology

This patent application uses a pump to push water to move in a flexible tube, and a detachable nozzle is set at the water outlet to control the position of the liquid, so that the cleaning angle is more comprehensive, but the cleaning solution is still the traditional water

[0004] To sum up, the existing pipeline cleaning methods have the following defects: First, the existing pipeline cleaning methods generally only achieve the cleaning effect, and a flushing process is required after cleaning, which has low efficiency and large water consumption. One type of method is to use chemical additives to achieve special cleaning effects, but this type of cleaning solution will cause pollution or corrosion to the equipment, and will also cause
