Method and device for using magnetic mirror theory to conduct sea water desalinization

Abstract

Provided are a method and a device for using a magnetic mirror theory to conduct sea water desalinization. The method and the device overcome the defect that a similar technique is not obvious on function effect for removing salt ions and has no practical application significance. The technical scheme is that the method and the device are characterized in that a non-uniform magnetic field which is distributed according to magnetic field intensity and provided with a top strong magnetic field and a bottom weak magnetic field is arranged at the position of seawater to be desalted, a vertically distributed rotation hollow cylinder is arranged in the magnetic field, a lower end port of the hollow cylinder serves as a water inlet below water face of the seawater to be desalted, a water outlet is arranged on the upper portion of the hollow cylinder, the hollow cylinder rotates to enable seawater in the cylinder to rotate through driving the inner wall of the hollow cylinder, the seawater close to the inner wall of the hollow cylinder rises along the inner wall of the hollow cylinder, then the seawater flows out from the water outlet on the upper portion of the hollow cylinder, the water level of the seawater in the cylinder is arc with low middle and high periphery, and collected water flowing out from the water outlet of the hollow cylinder is desalination water. The device is formed by a frame which is correspondingly installed, a non-uniform magnetic field generation device, the hollow cylinder, a bearing, a motor, a transmission mechanism and the like.

Description

technical field [0001] The invention relates to a seawater desalination method and equipment thereof, in particular to a method and a device for separating fresh water from seawater by means of magnetic separation. Background technique [0002] As we all know, sea water accounts for 97.3% of the total water reserves on the earth, and fresh water only accounts for 2.7%. Since seawater contains , , The brackish water with various salt ions cannot be directly used by human beings. Two-thirds of the fresh water is in glaciers and snowfields, and it cannot be directly used by humans. The total amount of rivers, rivers, lakes, lakes, ponds and groundwater available to humans only accounts for a very small proportion of the total water on the earth. In the fresh water distribution of human activities, agricultural irrigation accounts for 67%, industrial production accounts for 23%, and municipal civil use accounts for 10%. Since the beginning of this century, with the rapid...
