Problems solved by technology
[0011] Although the monomolecular film can inhibit the evaporation of the lake surface of the reservoir is better, but due to the high cost of the monomolecular film, the constraints of factors such as wind force, sand dust, wind and waves in the external environment, its popularization and application is not ideal.

Embodiment Construction
[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0063] figure 1 It is a schematic structural diagram of a system using graphite powder to prevent evaporation of a reservoir shown in an embodiment of the present application. refer to figure 1 , the system for preventing reservoir evaporation of the present application includes: reservoir 1, reservoir embankment 2, anti-adsorption layer 3, water pump 4 and flake graphite powder 5;
[0064] The flake graphite powder 5 is laid on the surface of the liquid surface of the r...

The invention provides a system by using graphite powder to prevent reservoir evaporation. The system includes the reservoir, a reservoir embankment, an anti-adsorption layer, a water pump and crystalline graphite powder; the crystalline graphite powder is laid on the liquid level surface layer of the reservoir to form a discontinuous graphite powder thin film, and thus water evaporation of the reservoir is prevented; when the system is used for preventing water evaporation of the reservoir, on one hand, the discontinuous thin film formed by the crystalline graphite powder acts the function of preventing water evaporation of the reservoir, on the other hand, the discontinuous thin film has cracks, the cracks act the function of gas exchange, oxygen in the air enters a water body, the breathing demands of aquatic animals and plants in the reservoir are met, and meanwhile, releasing of harmful gases in the water body of the reservoir is also facilitated; the system also has the functions of purifying the water body of the reservoir, reducing the leakage loss of the reservoir, and saving water, meanwhile pollution the graphite powder to the water body of the reservoir is small, and the price is low.
Description
technical field [0001] The application relates to the technical field of water conservancy engineering, in particular to a system for preventing reservoir evaporation by using graphite powder. Background technique [0002] Evaporation is one of the leading factors in the natural water cycle process and an important component of the three major elements of water balance. The arid region in Northwest my country is one of the areas with the most severe water shortage in China, with an average annual precipitation of 230 mm and an evaporation capacity of 8 to 10 times that of precipitation. [0003] Taking Xinjiang as an example, the annual average evaporation is 2463.6mm, and the annual average precipitation is only 147mm. At present, 489 reservoirs have been built in Xinjiang, with a total storage capacity of 83.78×10 8 m 3 . Studies have shown that the annual evaporation of plain reservoirs in Xinjiang is 26.1×10 8 m 3 , the lake surface evaporation loss exceeds 40% of ...
