Solar seawater desalination synergistic waste heat power generation device

Abstract

The invention provides a solar seawater desalination synergistic waste heat power generation device, and belongs to the field of seawater desalination. According to the specific technical scheme, thesolar seawater desalination synergistic waste heat power generation device comprises a seawater evaporator, a gas guide pipe and a power generation device body. The seawater evaporator is a closed cavity. The seawater evaporator is connected with the power generation device body through the gas guide pipe. A porous material which can float on seawater is arranged in the seawater evaporator. The horizontal plane of the seawater injected into the seawater evaporator is lower than a communication interface of the gas guide pipe and the seawater evaporator. The power generation device body is a vapor condensation power generation device body. Through the porous characteristic of sponge, the surface of the power generation device is modified to efficiently absorb solar energy, water molecules on a phase interface of seawater and air can efficiently collect heat, and then vapor is generated for seawater desalination.

Description

technical field [0001] The invention belongs to the field of seawater desalination, in particular to a solar seawater desalination cooperative waste heat power generation device based on the reuse of waste sponges. Background technique [0002] The average amount of water resources per person per year in my country is only 2,600 cubic meters. It is a country seriously short of water. Accompanied by the serious seawater intrusion caused by the over-exploitation of groundwater in coastal cities and mining areas, the local fresh water shortage problem is particularly prominent. This not only reduces agricultural production, but also seriously affects human health. At present, one of the effective means to solve the shortage of water resources is seawater desalination technology, but the current seawater desalination technology has the following problems: distillation method, due to high requirements for equipment and high energy consumption, cannot be put into large-scale use; ...

Problems solved by technology

At present, one of the effective means to solve the shortage of water resources is seawater desalination technology, but the current seawater desalination technology has the following problems: distillation method, due to high requirements for equipment and high energy consumption, cannot be put into large-scale use; ion exchange method , the waste liquid produced is extremely difficult to recycle, causing great environmental pollution and high energy consumption; passive evaporation technology, insufficient utilization of solar energy, thus reducing the efficiency of steam generation

A large amount of sponge waste and leftovers are treated as garbage, and the process of decomposing these sponges by nature is very long; and if the sponge waste is disposed of by burning, it will also have a bad impact on the environment
