Description

Technical Field

[0001] The utility model relates to the technical field of geothermal water treatment, in particular to a geothermal water sand removal device. Background Art

[0002] Geothermal resources are a kind of precious natural wealth. It can be used as a heat source, water source and mineral resource. Geothermal water with a temperature below the saturation curve is called unsaturated geothermal water, and geothermal water with corresponding temperature and pressure is called saturated geothermal water. Under saturated state, steam and water coexist, so saturated geothermal water refers to the liquid water part in the two-phase coexistence system. If the temperature remains liquid when it exceeds the saturation point, it is called superheated geothermal water, or simply superheated water. Superheated water is produced when the ambient temperature suddenly rises, or the confining pressure suddenly drops and the saturated hot water has no time to vaporize. Superheated water is very unstable and it always tends to transform into a mixture of saturated steam and water. The temperature of deep groundwater is generally between 25 degrees Celsius and 53 degrees Celsius. The water contains many trace elements that are beneficial to the human body. It is an ideal drinking water and bathing water. However, geothermal water is often mixed with mud and sand when it is mined and cannot be used directly.
