Problems solved by technology

There are two defects in this patent application. One is that if the concentration of the aerosol introduced is high, since the high concentration aerosol directly contacts the electrode, it is easy to pollute the electrode and affect the power dissipation effect.
The second is that the principle of this kind of dissipating device is that the charged aerosol particles will tend to the electrodes in the high electric field, and the charged particles will be captured by the electric field. The application of this device will change the composition of the aerosol, that is, change the particle size The proportion of gears, the removal of charged aerosol particles, and the passage of uncharged particles will affect the accuracy of aerosol research and limit its application range

Embodiment Construction

[0013] The main principle of the present invention is: the positive and negative high voltages are generated by the high voltage power output device of the electrostatic neutralizer, and the positive and negative high voltage electrodes are powered to make the positive and negative high voltage electrodes generate corona. When the clean air passes through the corona area of ​​high-voltage discharge, the air will take away the positive and negative ions rich in the corona area, and mix with the charged aerosol air to achieve the electrostatic balance of the charged aerosol, so that the static electricity passing through the electrostatic neutralizer The air reaches Boltzmann charge equilibrium.

[0014] The aerosol electrostatic neutralizer of the present invention, as shown in Figure 1, consists of two parts: a high-voltage power supply output device 5, a high-voltage electrode and an air circuit. 1 in the figure is the box of the neutralizer, and the high-voltage electrode 6 ...

Abstract

The present invention belongs to aerosol filter and relative equipment detecting technology field, relates to a aerosol electrostatic eliminator, comprising an electrostatic eliminating box, high voltage electrical source output device, and two high voltage electrodes, the electrostatic eliminating box is arranged with an air inlet, an air outlet and a mixed air open, the air inlet position opposites to the air outlet, the two high voltage electrodes separately are fixed at two sides of the box, the box inner is fixed with earth-plate, the output of the high voltage electric source output device connect to the two high voltage electrodes. The present invention can balance charge of the aerosol under the condition without change the ratio of particle size shift, leading charge distribution to content Boltzmann distribution.

Description

technical field [0001] The invention belongs to the technical field of detection of aerosol filters and related equipment. Background technique [0002] Static eliminators, there are related products at home and abroad at present, but they are all for static removal of clean air, that is, positive and negative ions in the air are removed in an electric field, and the purpose is to provide an air source without static electricity. However, in the field of aerosol research, when the aerosol particles under study are charged, the research results will be affected. Therefore, an instrument for electrostatic neutralization of charged aerosols is needed to reduce the charge in the aerosol to Boltz Mann balance, thus providing a stable and uniformly charged aerosol supply source. At the same time, it is also used when the aerosol required in the production process or other processes reaches electrostatic equilibrium (ie Boltzmann equilibrium). [0003] With the advancement of sci...
