Description

The invention relates to medical and sanitary equipment and can be used to saturate the air of working areas with light negative ions in the range of required sanitary standards.

The well-known classical electro-effluent ionizer is Chizhevsky’s “chandelier” [see, for example, A. Chizhevsky Air ions and life, M., Thought, 1999, pp. 158-167] - analogue.

Chizhevsky’s chandelier contains a high-voltage source of constant negative voltage, a high-voltage cable leading to the chandelier, a prickly “umbrella” with a diameter of about 1 m of corona electrodes, suspended from the ceiling.

The disadvantages of the classic ionizer Chizhevsky include:

- the formation of a mud stain near the chandelier (ceiling, wall) about a month after its suspension;

- non-transportability, significant dimensions of the device, worsening the design of the working area;

- uneven distribution of air ions in the surrounding space, determined only by the natural turbulence of the air of the working area.

The closest analogue to the claimed device is "Aeroionizer", Patent RU No. 2135227, 1999, Cl. A61N, 1/44. The aeroionizer contains a corona electrode and a dielectric housing with a converter for supply voltage to a high voltage constant voltage integrated therein, the positive pole of which is galvanically connected to the supply network, the housing is equipped with a connector through which a corona electrode is attached to the housing and connected through a resistor to the negative pole of the high voltage , the internal volume of the housing is sealed with a dielectric compound, the corona electrode has the shape of a dandelion, about dyne the end of the base of which is equipped with a part of the connector, and to the other end is a piece of wire from needles having a corolla shape.

A disadvantage of the closest analogue should be considered a significant spatial uneven concentration of aeroions in the working area, determined only by the natural turbulence of the air in the ionized space.

The objective of the invention is to provide a more uniform concentration of aero ions in the surrounding space by swirling the magnetic field of the solenoid created by the corona current flowing through the solenoid.

The technical result is achieved by the fact that the air ionizer contains a dielectric housing with a converter for supply voltage to a high voltage constant voltage integrated therein, the positive pole of which is galvanically connected to the supply network, the internal volume of the housing is filled with a dielectric compound, the housing is equipped with a connector through which a corona is attached to the housing an electrode equipped at the end with a needle rim connected through a resistor and a connector with a negative pole of high voltage Further resistor is made variable, and between the connector and the rim has a needle solenoid configured to ions sewage flow in a direction coinciding with the axis of the solenoid.

The invention is illustrated by drawings, where:

figure 1 - electrical diagram of the ionizer;

figure 2 - Maxwell distribution of air molecules in speed;

figure 3 - swirl of a moving charge in a magnetic field;

figure 4 - spatial concentration of aeroions at a distance from the source: a) the inventive ionizer, b) the closest analogue.

The air ionizer (Fig. 1) contains a dielectric housing 1, a high-voltage power supply 2, compound filling 3 of the elements of a high-voltage power supply, a resistor 4 of the corona electrode power circuit, connector 5, a solenoid 6, a corolla of needles of the corona electrode 7.

где q - величина заряда частицы,

- вектор индукции магнитного поля [см., например, Советский энциклопедический словарь, под редакцией A.M. Прохорова, М., Советская энциклопедия, 1989 г., стр.735, Лоренца сила].The dynamics of the interaction of elements is as follows. Air molecules are in constant motion. The speed of molecules depends on internal energy, the average value of which is 3/2 kT. The entire range of molecular velocities is specified by the Maxwell distribution and is illustrated in FIG. It is known that a Lorentz force acts on a moving charged particle in a magnetic field:

where q is the particle charge,

is the vector of speed of movement,

- magnetic field induction vector [see, for example, Soviet Encyclopedic Dictionary, edited by AM Prokhorov, M., Soviet Encyclopedia, 1989, p. 735, Lorentz force].

где m - масса аэроиона кислорода воздуха. Кроме завихрения, аэроион приобретает преимущественное направление перемещения вдоль линий напряженности магнитного поля. При известных постоянных значениях величин q, m, ν аэроиона радиус завихрения R зависит только от выбора значений величины

. Напряженность магнитного поля на оси соленоида при величине тока коронирующего электрода 2-3 мкА полностью определяется конструктивными размерами соленоида: числом витков, диаметром навивки, длиной. При значениях тока коронирования 2-3 мкА полное завихрение аэроионов внутри соленоида обеспечивается при следующих конструктивных размерах: диаметр навивки 30 см, длина 15 см, толщина медного провода навивки в изоляторе 1 мм, число витков n=150. Величину индукции магнитного поля соленоида и режим коронирования регулируют переменным резистором 4.The Lorentz force does not do the work, but only bends the trajectory of the charged particle. The swirl of particle motion in a magnetic field is illustrated in FIG. The turbulence occurs along a helix, the radius of curvature of which is determined from the relation:

where m is the mass of air ion of oxygen. In addition to the turbulence, the aeroion acquires a preferred direction of movement along the lines of magnetic field strength. For known constant values of q, m, and ν of the air ion, the swirl radius R depends only on the choice of the values of

. The magnetic field strength on the axis of the solenoid with a current of the corona electrode of 2-3 μA is completely determined by the design dimensions of the solenoid: the number of turns, the diameter of the winding, the length. At values of the corona current of 2–3 μA, a complete swirl of aero ions inside the solenoid is ensured with the following structural dimensions: winding diameter 30 cm, length 15 cm, thickness of the copper winding wire in the insulator 1 mm, number of turns n = 150. The magnitude of the magnetic field induction of the solenoid and the corona mode are controlled by a variable resistor 4.

The short solenoid functionally acts as a “horn”, which makes it possible to channel the flow of aero ions in one of the preferred directions coinciding with the axis of the solenoid. Thanks to the canalization of the flow of aeroions, their higher concentration is ensured in the working area at a considerable distance from the corona electrode. The change in the spatial concentration of aeroions at a distance from the corona electrode of the claimed ionizer and the closest analogue is illustrated in Fig. 4, where (dashed line) indicates the sanitary norm for the concentration of aeroions according to SanPiN 2.24.1294-03.

As follows from the above graphs, the effectiveness of the claimed ionizer exceeds the efficiency of the closest analogue by more than two times.

All elements of the ionizer are assembled according to standard electronic circuits and on the existing elemental base.

The high-voltage voltage source (Fig. 1) contains a pulse generator power rectifier (diode D1 1N4005, capacitor C1 2.2 μF, voltage divider R1 24 kΩ, R2 470 kΩ, R3 30 kΩ), a pulse generator (thyristor Q1, SCR-TS820, dynistor Q2 (DIAC)), pulse transformer Tp1 CD-25B, capacitor C2 0.3 μF, voltage multiplier (diodes D2, D3, D4, D5 - ESJA53-20A, capacitors C3, C4, C5, C6 at 590 pF), resistance (4) in the corona electrode circuit is 20 kO m (4 W).
