Description

(54) ELECTRIC AIR DIVIDER

one

The invention relates to devices for separating gaseous and liquid substances obtained by mechanical washing of ingredients.

An air oxygen generator is known, which consists of a mesh cooler that sucks in a nozzle, in which armor-type magnet cores with multi-sided conical slots are installed, and the corona electrodes are located in front of the slots along the magnetic field of system 1.

The disadvantages of such a device are its low efficiency, since in the armor-type core, the magnetic flux path is increased, resulting in increased magnetic resistance, as well as the complexity and intensity of the design due to the presence of multi-sided conical slots x

The purpose of the invention is to increase efficiency and simplify the design of the device.

This goal is achieved by the fact that in an electric air separator containing a housing, a magnetic circuit with cracks and corona electrodes, a refrigerator and a heater, the magnetic conductor is filled in the form of segments with an electric windings located along a generatrix of a conical surface.

corona electrodes 7. In the re-cooler 12, the pre-cooled rotor part is installed to a temperature of about + 10 ° C, 8, the rotor - heater 9 s is directed to the L5 branch pipe 10. There is a flange 11 in the butt of the case, and a fridge in the front part 12, the blower of separation products 13. The electric air separator operates as follows. Direct current 50-200 is passed through the windings 5, a voltage of 3–40 kV is applied and the blower 13 is turned on. Atmospheric air under pressure of 1-3 atm from the blower 13 passes through the mesh refrigerator 12 and enters the zone of intersection of the magnetic and static fields received due to the current; in the windings 5 and the voltage to the melody by the crushing electrodes 7 and the segments 4, the nitrogen of the air is ionized earlier than oxygen, since the dielectric constant of nitrogen is 1, O09 times less than oxygen. In the ionized (conducting) layer of nitrogen from the intersection with the magnetic field (cutting emf is induced, as a result of which the conductive layer of nitrogen pushes out of the zone of influence of the magnetic field, and the oxygen produced by the magnetic field is pulled into the slot 6. Thus, In addition to the supply of additional volume of air in the housing 1 from the suppressor 13, it is divided into two streams enriched in nitrogen (outer layer) and enriched in oxygen (inner layer). The outer layer is removed from the overpressure and inside the housing 1 through the opening 11 of the flange 11 through the slots 6 of the rotor 2 and heater 9, where oxygen is demagnetized, is diverted by the guide pipe 1O to the process air outlet (not shown). As the magnetic sensitivity of the air changes inversely proportional to its temperature, The customers regulate the current in the windings 5, the voltage between the discharge electrodes 7 and the segments 4, as well as the change in the speed of the air (total) flow and the O2 and Nrj separated relative to each other. An electric air separator of this design can be installed on fans for supplying combustion air to heating wells for heating ingots weighing up to 26 g. Air consumption is up to 18,000 m / h. The supply of enriched air with oxygen in a blast furnace to 10,000. The electric air separator has a high efficiency due to low Marw resistance, since the magnetic core is only the segments and the air space between them, the simplified design, the increased reliability in operation, does not require large capital expenditures, ensures obtaining almost any oxygen concentrations in the blast, has a relatively low hydraulic resistance to air movement (50-100 mm water column). Claims An electric air separator comprising a housing, a magnetic core with gaps and corona electrodes, a cooler and a heater, characterized in that, in order to improve efficiency and simplify the design of the air splitter, the magnetic circuit is formed in the form of segments with electric windings located along a conical surface.
