Description

The invention relates to the treatment of wastewater from mineral impurities by magnetic treatment and can be used in treatment systems of industrial and mining enterprises.

The purpose of the invention is to increase the efficiency of desalination, simplify manufacturing and reduce the size of the device.

The drawing shows a device for desalting solutions.

The device contains a magnetic system in the form of a solenoid 1 mounted on a shaft 2, which is connected to the drive 3. A cylindrical housing 4 with an inlet pipe 5 is mounted concentrically on the shaft 2 on the shaft 2. A working chamber 6 is placed inside the housing 4, mounted on the solenoid 1, the cavity which is divided into three concentric chambers 7. 8 and 9 permeable walls 10 and 11, made in the form of shells, for example, of porous titanium. The inlet pipe 5 and the outlet pipe 12 for discharging treated effluents are connected to the chamber 8. The outlet pipes 13

for discharging cleaned effluents, they are connected to chamber 8. Outlet pipes 13 for discharging sludge are connected to chambers 7 and 9. Pipes 12 and 13 are located in the lower part of the housing.

The device operates as follows.

A current is supplied to the solenoid 1 and the drive 3 is turned on. The solution to be treated (siphons) enters through the inlet pipe 5 into the concentric chamber 8. As a result of the rotation of the solenoid 1 inside the housing 4, a rotating magnetic field is created and the ions contained in the treated solution begin to act Lorentz forces that move ions toward the concentric chambers 7 and 9. The solution enters the chamber 8 under a pressure of 1 MPa. allowing the solution to leak through the permeable partitions 10 and 11. The exposure time is 15-20 minutes. As a result of the action of a rotating magnetic field, metal ions pass through permeable walls 10 and 11 to peripheral

chambers 7 and 9, respectively, with anions and cations entering different chambers. The cleaned effluents through the outlet 12 are discharged by gravity. A solution saturated with ions of one sign is discharged by gravity through one of the nozzles 13, and a solution saturated with ions of another sign. - through another pipe 13.

The placement of the magnetic system - the solenoid V is not outside, but inside the housing 4 leads to a decrease in size than before. the greater compactness of the device and simplification of the manufacture of the device are achieved. In addition, this arrangement allows an increase in the rotation speed of the solenoid, which contributes to an increase in the desalination efficiency. The location of the outlet pipes in the lower part of the housing allows you to remove the ion-enriched solution by gravity, which also increases the cleaning efficiency by reducing energy
