Description

An anti-clogging buried pipe

technical field

The utility model relates to the technical field of buried pipes, in particular to an anti-blocking buried pipe.

Background technique

At present, the ground source heat pump technology that uses natural energy such as water as the winter heat source, and then the heat pump unit supplies heat to the building has been widely promoted in the north. The working principle of the ground source heat pump technology is to use the water in the buried pipe The heat in the soil is obtained, and the water in the buried pipe is continuously recycled.

The above-mentioned existing technical solutions have the following defects: the water in the buried pipe is high-temperature water, and at high temperature, calcium sulfate containing slightly soluble in water will be precipitated due to the evaporation of water, and the carbonate in the water will combine with calcium and magnesium. The plasma is combined to generate calcium carbonate and magnesium carbonate that are insoluble in water, that is, water alkali. With the continuous evaporation and concentration of water, the alkali content of water increases continuously, and scale is formed after reaching saturation. If the scale is not cleaned for a long time after it is generated, it will easily stick to the inner wall of the pipe, greatly reducing the heat transfer effect of the pipe, affecting the heat transfer efficiency of the buried pipe, and even causing the blockage of the pipe, resulting in a pipe burst accident.
