Description

I The invention relates to techniques for high jjcnx voltages, in particular to generators for producing electro-aerosol sols, and can be used to produce charged aerosol in agriculture, medicine, and electronic-ion technology. of the invention is | 1 simplifying the design and reducing the size of the generator, i The drawing shows the proposed (generator of a charged aerosol, cut. | The device contains a grounded box jnyc with a nozzle 1 and an annular gap 2, obazhaet cavity for communication nozzle 1s source a corona electrode 4 is made on the ego axis, made of a porous material and constructed with the output of a high voltage source 5. In the case of the holder 3 there is a central axial cavity 6 for supplying

 steam and cavity 7 to communicate with a fluid supply source. In the corona electrode 4, an inner central cavity 8. is made which, by

the nozzle 9 communicates with the cavity 7 of the holder 3 to communicate with the fluid supply source.

The charged aerosol generator operates as follows. The high voltage from source 5 is applied to the high-voltage electrode 4, on which a corona discharge occurs. A large number of ions are produced. Steam passes through the charge gap 10.

. ions are carried away by their flux into the outer zone of the generator, where condensation occurs on them, and a charged aerosol is formed. When the humidity of the surrounding air is high enough, the liquid inside the cavity 8 in the corona electroi

de 4 is not served. With a decrease in air humidity in the outer zone of the generator, fluid begins to float from cavity 7 through pipe 9 to cavity 8. It should be noted that the liquid is supplied under pressure. Due to this, it passes through the pores of the material and enters the surface of the corona electrode, is carried away by the steam flow and enters the charge gap 10. The discharge of liquid into the charge zone 10 leads to the fact that the discharged aerosol does not have time to evaporate during its transportation from the generator to the target. With a further decrease in ambient humidity, the amount of liquid supplied into the corona electrode increases. This ensures the stability and efficiency of the charged aerosol generator.

The effect of stable ™ and generator efficiency is achieved without using
