Description

Device for producing highly dispersed aerosols of sodium chloride and light negative ions of oxygen

The device relates to medical equipment and can be used to treat diseases of the respiratory system, sleep disorders, hypertension, heart failure, and also to neutralize pathogenic microbes in the air atmosphere.

A well-known climatic chamber containing a treatment chamber with an air conditioning system, a salt filter-saturator, a hopper with a salt dispenser, a vortex chamber with an internal salt lining, its own circulation circuit, a flow inducer and a ventilation pipe system $ (see, author St. I I52I478, MKH , A6IG-IO / 02).

The disadvantages of this design are:

a) a complex system of conditioning and obtaining aeroyaoli salt,

b) the complexity of servicing the operation of the apparatus system due to the need for sequential opening of the ventilation and switching on

c) the inner surface of the vortex chamber is covered with salt

blocks that can quickly collapse under the action of vibration transmitted from the fan through the piping system and air flow,

g) the fan-inducer of the flow works in the pneumatic transport mode, the possibility of the breakthrough of large particles of salt through the central outlet pipe into the treatment chamber is not excluded,

e) the dosage of salt is done periodically manually, which can lead to instability of the content of aerosols of salt in the ventilation air.

The disadvantages of this design is that during operation, salt blocks adsorb moisture and vapors of various volatiles on their surface, saturated with them, lose strength and geometric shape. This design does not allow the creation of ionized air in the required amount.

Known climatic chamber, including air conditioning with pipelines, salt bins with nets, glass balls and a silk cloth (see aut. St.) and 1532035 MKI A6IG-10/02).

The disadvantages of this design is that the fluidization will occur unevenly, mainly in the flowing mode due to the conical shape of the hopper and the large shear of the plate inclination, in addition, due to the large length of the pipeline running around the entire perimeter of the climate chamber, air pressure will be lost as removal from the air conditioner, which will worsen fluidization in a number of bins. Silk fabric in the process of fluidization will be intensively worn and destroyed. In the fluidized bed there is a separation into fractions of particles of rock salt and glass balls, because the specific gravity of salt is 2.1 g / cm3 and that of glass 2.3 is 2.9 g / cm8. As a result of fractional separation of densities in a fluidized bed, the contact between salt and glass balls deteriorates, in addition, to liquefy rock salt with a particle size of up to 10 t and glass balls with a diameter of 16-20 mm, a high velocity fluidizing agent is required (about 30 m / s), and this leads to getting into the climate chamber both coarse and fine fractions.

Glass balls colliding collapse and small particles of glass fall into the climate chamber.

Known neutralizer (ionizer) of the air-ionization type with forced blowing with compressed air of the corona system (see Croatian T, Berta I. Neutralization of static electricity M.1987 p.71-72)

The disadvantage of this design is that the shell is blown only from the inside, when working in a fluidized bed, small fractions of salt particles will settle on the outer surface of the protective shell, increasing hydraulic resistance to flows, in addition, the design itself occupies a large volume in the fluidized bed preventing intensive mixing of particles in the layer.

This design does not provide stable contact between the needles and charged particles of the fluidized bed.

The purpose of creating this utility model is to increase the efficiency of procedures by improving the operation of the apparatus and increasing the concentration of highly dispersed aerosols of sodium chloride and light negative ions of oxygen, air, as well as simplifying the design and expanding the applicability of this device by minimizing the overall dimensions of the device and operating in various rooms volume and space.

In order to solve this problem, a fluidized bed (fluidized bed) apparatus with an induction ionizer nozzle on which grounded needles are located is used. The induction ionizer nozzle is placed in the casing above the gas distribution grid and is made in the form of a double grating with square cells, in the bumps of which there are metal needles, and the gratings in the double grating are offset one relative to the other in the horizontal plane by 1/2 the size of the side of the cell in two-dimensional coordinates, and the pointed protruding part of the needles of one lattice in a double lattice is located in the cells of another

lattice of the same double lattice, while the length of the pointed protruding part of the needles is equal to the height of the cell edge, limiting it. The body and the ionizer nozzle are made of dielectric plastic.

In FigL schematically shows the described device, a vertical section, in Fig.2 is a section aa in Fig.1, in Fig.Z section B-B in Fig.2.

A device for producing highly dispersed aerosols of sodium chloride and light negative oxygen ions of air contains a housing I with a gas distribution grid 2 and an induction ionizer nozzle 3 located above it. The induction ionizer nozzle 3 is made of two 4 and 5 identical gratings with square cells. Moreover, the lattices are displaced relative to each other in the horizontal plane by 1/2 the size of the side of the cell in two-dimensional coordinates. In nodes 6 of the gratings, metal needles 7 are located, which are grounded by a common wire 8. The pointed protruding part 9 of the needles of the grating 4 is located in the cells of the grating 5, and the pointed protruding part 10 of the needles of the grating 5 are in the cells of the grating 4, and the length of the protruding part of the needles is equal to the height of the rib cell, which protects the needle from mechanical damage. The housing and the induction ionizer nozzle are made of dielectric plastic (polyethylene), which allows a more qualitative process to obtain highly dispersed aerosols of sodium chloride and light negative ions of oxygen.

To conduct the process in the fluidized (fluidized) bed, the polydisperse fraction table salt is loaded into the device body I onto the gas distribution grid 2, through which the supplied fluidizing agent (air) passes, converting the table salt to the fluidized state. Up and down air flows with particles of salt

pass through an induction ionizer-nozzle 3. As a result of intensive mixing of the particles of sodium chloride, their partial abrasion to particles of a finely dispersed aerosol no more than 10 microns in size occurs. The speed of the fluidized agent is greater than the velocity of the particles of the finely dispersed fraction, as a result of which the particles of the finely dispersed fraction are taken out of the fluidized bed. Changing the speed of the fluidizing agent allows you to adjust the concentration and size of aerosols of sodium chloride in the air leaving the device. In a fluidized state, due to intensive mixing of the bed, a volumetric electrostatic charge is created on the surface of the salt particles. When passing under the influence of ascending and descending flows in a fluidized bed through an induction ionizer nozzle between the pointed protruding parts 9 and 10 of the grounded needles 7 and electrified particles, impact ionization of air occurs under the influence of a strong electric field near the discharge electrode (needle tip), as a result ions of both signs. According to the triboelectric series, table salt in a fluidized bed acquires a positive charge. The mobility of negative ions is 1.5 times greater than the mobility of positive ones, therefore, positively charged salt particles are more quickly neutralized with the release of the highest ionization energy of the air, therefore, light negative oxygen ions and highly dispersed sodium chloride aerosols predominate in the air leaving the I body, which allows to enhance the effect of medical procedures .

The displacement of lattices 4 and 5 in a double lattice by 1/2 the size of the side of the cell allows more efficient to break and destroy air bubbles in the fluidized bed, as a result of which the fluidized bed becomes more uniform, and the location of the needles in

opposite sides of the points (in the cells of another lattice from a double lattice) allows to increase the contact between the ascending and descending flows of salt particles in the fluidized bed, which leads to an increase in the concentration of ionized air and fractional uniformity of the salt aerosol.

The location of the protruding pointed part of the needles in the cells and the limitation of their length to the height of the edges of the cell can also protect them from mechanical damage, increasing the service life.

The execution of the body and nozzle made of dielectric plastic improves the conduct of the process itself, especially in the case of the nozzle - there is no screening of the needle tip, which thereby creates maximum conditions for ionization of the air.

The described device can be manufactured while maintaining its usefulness in various sizes, which allows it to be used in both small and large volumes and areas.
