Embodiment Construction

[0018] Such as figure 1 As shown, the equipment for directly extracting heavy water by using solar energy is: N+1 containers made of materials with high-efficiency absorption of sunlight, a water vapor collector and a heavy water collector; two conduit stages are passed between the containers. Connected, one conduit is a water conduit, used for water conduction between containers, and one conduit is a water vapor conduit, used to introduce N+1-level water vapor into N-level water; said The water vapor collector is connected to the first-level container and is used to collect the water vapor in the first-level container; the heavy water collector is connected to the N+1-level container and is used to collect the heavy water in the N+1-level container . In order to speed up the conversion efficiency, on the one hand, a waterproof electric fan can be installed in the water vapor conduit to quickly extract the water vapor in the N+1th container into the Nth water; on the other h...

Abstract

The invention relates to a method and equipment for producing heavy water by utilizing solar energy. The equipment consists of (N+1) containers which efficiently absorb sunlight, a steam collector and a heavy water collector. The method comprises the following steps that (N+1) level of distillation on natural water is carried out by using solar energy, wherein common water of the Nth level flows into the (N+1)th level, and steam formed by radiation and evaporation of sunlight of water in the (N+1)th level is guided to water of the Nth level; steam is collected in the first level, light water is condensed, and water in the (N+1)th level is collected to obtain high purity heavy water. The method and the device provided by the invention have the advantages that the equipment of extracting heavy water has the characteristics of simple structure, convenient construction and low cost; as heavy water is extracted by directly using solar energy, emission of carbon dioxide is reduced while the cost is saved.

Description

technical field [0001] The invention relates to a method and equipment for extracting heavy water, in particular to a method and equipment for directly extracting heavy water by using solar energy. Background technique [0002] There are currently two basic types of nuclear power plants around the world, one using heavy water reactors and the other using light water (ordinary water) reactors. Both types have their advantages and disadvantages. , because light water can absorb neutrons, it is necessary to use enriched uranium in nuclear reactors. The use of enriched uranium has the defects of low safety and high cost; and because heavy water does not absorb neutrons, it is the best moderator, so heavy water nuclear reactors can Using natural non-enriched uranium has low cost and relatively high safety, but the disadvantage is that heavy water is expensive. So adding up, the cost of light water nuclear power plants and heavy water nuclear power plants is about the same. [...
