Description
Technical Field
The invention relates to the technical field of VOCs treatment, in particular to an aerosol trap.
Background
Aerosols are colloidal dispersions, also known as gas dispersions, of small particles of a solid or liquid dispersed and suspended in a gaseous medium. The dispersion phase is solid or liquid small particles with the size of 0.001-100 microns, and the dispersion medium is gas. Clouds, fog, dust in the sky, smoke from unburned fuel in industrial and transport boilers and engines of all kinds, solid dust from mining, quarry grinding and grain processing, artificial masking and toxic fumes are examples of aerosols. Haze is a phenomenon that a large number of extremely fine dry dust particles and the like float uniformly in the air, so that the air with horizontal visibility of less than 10 kilometers is generally turbid, wherein the dry dust particles refer to dry aerosol particles. Generally, when the visibility is 1-10 km, the influence of dry aerosol (namely, the influence of haze) and the contribution of water drops (namely, the contribution of light fog) are possible, and the visibility is not easy to distinguish, so the visibility is called as a 'haze' phenomenon. Since no aerosol particles are present in the actual atmosphere as condensation nuclei (or ice nuclei) of the cloud and no mist can be formed, the back of both the mist and the haze is associated with the aerosol particles.
The aerosol catcher can remove more than 98% of various VOCs components in an exhaust gas source (VOCs source generated by related industries), thereby greatly reducing the amount discharged into the atmosphere. Its main part work part comprises corona polar array and two parts of sediment polar array, forms the high voltage direct current electric field between two big polar arrays through power supply conversion, when VOCs or other if: waste gases such as dust, white smoke steam, odor, dioxin, sulfide and the like generate a series of physical and chemical reactions when passing through an interelectrode electric field, the molecular structures of the gases are damaged, new charged particles are formed, the charged particles are adsorbed on the surface of a precipitation electrode under the action of a high-voltage direct-current electric field, meanwhile, partial particles can be recombined to generate new micromolecule gaseous substances for safe discharge, and partial newly generated liquid substances can flow to the bottom of equipment along the precipitation electrode under the action of gravity and are discharged through a drain outlet.
