Abstract

The invention relates to wastewater treatment devices and improves the quality of water purification and reduces the consumption of reagents used in the water treatment process by installing electrodes 5 without isolating them from the housing 1, which is split into two parts and simultaneously performs the functions of conductors. power supply from the direct current filter to the electrodes located around the circumference and mounted on each section of the magnetic circuit. Sectioning of the body of the magnetic circuit is provided by installing insulating current-non-conducting strips 2 of ferritic magnetic material that must be magnetized and their polarity matched with the polarity of the magnetizing coil 4 so that the magnetic flux and electric current flow through the electrodes and for uniform fluid supply in the bottom Part of the device is located distribution system 6. 2 Il.

Description

around the circumference and installed on each section of the magnetic circuit. The sectioning of the body of the magnetic circuit is provided by installing insulating current-conducting strips 2 of the ferritic magnetic material, which must be magnetized and their polarity matched with the polarity of the magnetizing coil 4; so that the magnetic flux and electric current pass through the electrodes, and for an even supply of liquid in the lower part of the device there is a distribution system of 6, 2 sludge.

The invention relates to devices that provide an intensification of the process for the preparation of aqueous solutions, intended for the purification of natural and waste waters of chemical, metallurgical, machine-building, municipal enterprises and other industries.

The purpose of the invention is to improve the quality of water purification and reduce the consumption of reagents used in the process of water treatment.

Figure 1 shows the device, a longitudinal section; figure 2 - section aa in figure 1.

The device contains a prefabricated housing 1 of the magnetic circuit, made of a magnet of soft steel. The housing is divided into two parts by non-conducting ferritic magnetic pads 2, inside is located a cylinder 3 of insulating non-magnetic material, on which the magnetizing coil A of the electromagnetic systems, electrodes 5, mounted circumferentially on the lower and upper magnetowires with alternating polarity. The optimum number of electrodes and their design dimensions depend on the performance of the device and the required concentration of saturation of the solution, which is determined by appropriate calculations. The device is equipped with a distribution system 6 of equal fluid supply and a discharge pipe 7, arranged in such a way that it is between the case and the lower electro. There is a space for collecting hydrogen, it is discharged through pipe 8 outside the room through a dielectric plug. Terminals 9 are connected to the lower and upper sections of the magnetic circuit to supply direct current to the electrodes. The magnetic core is fastened with bolts 10 with dielectric

gaskets. A terminal box for the magnetizing coil is installed on the body of the magnetic conductors, which serves to connect the wires from the DC torrent.

The device works as follows.

The processed solution enters the device through the distribution system 6 of the uniform liquid supply, passes between the electrodes-5, where it is subjected to the simultaneous influence of the magnetic field created by the electromagnetic coil 4 and the direct current passing between the electrodes. Owing to electrolysis and the presence of a magnetic field, the treated solution is intensely pressed by iron hydroxide and enlarged floccules are formed, which play the main role in the flocculation of contaminated fluids. The waste liquid is discharged through the pipe 7. During electrolysis, the formed hydrogen is discharged through the pipe 8.

At full consumption of the material of the electrodes, they should be replaced with new ones. For this purpose, it suffices to release the device from the liquid and replace them 1.
