3D printing sea water desalination chip device based on ion concentration polarization principle

Abstract

The invention relates to a 3D sea water desalination chip device based on an ion concentration polarization principle. The 3D sea water desalination chip device comprises a base adopting 3D printing and a shell adopting 3D printing, a convexly formed buffer solution channel is formed in the base, and a micro-nano membrane channel, a desalted water channel, a concentrated saline water channel and a water outlet are also formed in the base; after the shell and the base are combined, a saline water channel is formed. After a 3D printing material is adopted for combination, fit is tight, no seam is formed, and leakproofness is extremely good; the base and the shell are clamped, connected and fixed by virtue of a 3D printing surrounding edge, the fixed position is accurate, glue or a nail does not need to be used, the integrity can be guaranteed, and the device can not be destroyed by the glue or nail; the manufacturing cost is low, and the device has mass production potency and is recyclable; the device is supported by 3D printing, so that the precision of the dimensions and shape of the device is not limited by familiarity degree of skills of workers, and the obtained finished product has relatively good dimensions and precision; the ion concentration polarization principle is utilized for carrying out sea water desalination, the energy consumption is low, the desalination efficiency is high, and no harm is done to the environment.

Description

technical field [0001] The invention relates to a 3D printed seawater desalination chip device based on the ion concentration polarization principle, and belongs to the technical field of seawater desalination. Background technique [0002] As of 1990, the water production capacity of installed seawater desalination plants in the world was about 13,000,000 cubic meters per day, and by 2000, this production capacity had doubled. The problem of energy consumption has become increasingly prominent with the increase of desalinated water production capacity. It is calculated that to produce 13,000,000 cubic meters of desalinated water every day, 130 million tons of crude oil will be consumed within a year. The cost of fuel is not the main problem. The air pollution and greenhouse effect of the earth are the problems that people must be cautious about. [0003] Among the more than twenty known seawater desalination methods, the ones that are widely used and have industrializatio...

Problems solved by technology

[0004] In 2009, SungJaeKim[5] et al proposed a microfluidic seawater desalination device based on the principle of ion concentration polarization, which provided a new development direction for the development of seawater desalination, but SungJaeKim et al. only discussed ion concentration polarization The possibility of applying the principle in the direction of seawater desalination has not actually proposed a device model that can be mass-produced
