Embodiment 1

[0023] Example 1 The rust prevention and rust removal method of the water pipeline is to insert an outer pipe body on the water pipeline as a cathode, the two ends of the outer pipe body are connected to the water pipeline through flanges, and a water contact is set in the outer pipe body. The metal inner core is used as an anode, and the water flow in the water pipeline fully contacts with the metal inner core set in the outer tube body. The potential difference between the anode and the cathode reduces the binding force between the rust in the water pipeline and the inner wall of the pipeline, and sacrifices the anode to soften the water quality, so as to realize the function of rust prevention and pipeline protection. The outer pipe body is made of copper alloy, and the metal inner core set in the outer pipe body is made of magnesium alloy, and the two ends of the outer pipe body are connected with the water pipeline through flanges.

Abstract

The invention provides a method for preventing and removing rust of a water pipeline. The invention is characterized in that the method comprises the following steps: the water pipeline is connected with an external pipe body as a cathode; a metal inner core contacting with water flow is arranged in the external pipe body as an anode; bonding force between the rust in the water pipeline and the inner wall of the pipeline can be reduced by potential difference between the anode and the cathode, and the anode is sacrificed to realize the functions of rust prevention and pipeline protection. The invention also provides a device for preventing and removing rust by the method. The method for removing rust in the water pipeline and the device thereof can remove the rust by the physical power of the water flow, by ion flow generated between the external pipe body and the metal inner core and by the soft action of the metal inner core to water, can not only have excellent rust removing effect, but also have the advantages of long service life, economy and practicality, energy conservation and environmental protection, have the function of softening water quality, and are suitable for rust removing operation for water pipelines with different temperatures and diameters.

Description

technical field [0001] The invention belongs to the technical field of rust removal and antirust technology and devices for water pipelines, and in particular relates to a rust prevention and rust removal for water pipelines that utilizes the potential difference between cathodes and anodes to realize rust prevention and rust removal for water pipelines The method and the rust prevention and rust removal device adopting the rust prevention and rust removal method. Background technique [0002] Scaling and rusting of water pipelines are currently difficult problems encountered in water treatment. In order to eliminate scale and rust in water pipelines, physical and chemical methods are generally used. Common physical methods include mechanical cleaning and pipeline lining. For example, high-pressure jet method and mechanical scraping method are used to mechanically clean the rust on the inner wall of the water pipeline. This method can only be applied to the non-operating sta...
