Abstract

The invention discloses a sea water desalinization apparatus based on Fresnel lens and solar carburetor process, comprising a sea water delivery pipe, a Fresnel lens solar heating mechanism, a solar power generation mechanism, a carburetor venturi tube, a desalinized sea water storage tank, a blowing mechanism, a cooling pipe and a controller; the sea water delivery pipe is connected with the input end of the Fresnel lens solar heating mechanism; the output end of the Fresnel lens solar heating mechanism is connected with the minimum middle sectional area part of the carburetor venturi tube; the blowing mechanism is arranged on one side of the carburetor venturi tube, and negative pressure is generated at this side so that high-temperature sea water entering the carburetor venturi tube turns into vapor that enters the other side of the carburetor venturi tube; the other side of the carburetor venturi tube is provided with a plurality of moisture permeable membranes in spaced manner; the lower portion of the other side of the carburetor venturi tube is provided with a water outlet; the water outlet is connected with an inlet line of the desalinized sea water storage tank; the cooling pipe is wound on the outer periphery of the other side of the carburetor venturi tube. The sea water desalinization apparatus based on Fresnel lens and solar carburetor process is simple in structure, reliable to implement and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a Fresnel lens solar carburetor seawater desalination device. Background technique [0002] With the continuous increase of the earth's population and the rapid increase of environmental pollution and emissions brought about by the development of the national economy, the pressure on water resources and the water environment has increased sharply, and the global water shortage problem has become increasingly serious. Fresh water is one of the basic materials for the survival and development of human society. In terms of per capita possession, China is a poor country in terms of water resources. According to estimates, my country's per capita water consumption only ranks 108th in the world. my country has a long coastline, and some islands, coastal saline-alkaline areas, and inland brackish water areas are areas that lack fresh water. Therefore, solving the shortag...
