Embodiment Construction

[0065] In this embodiment, the air flow flows spatially from bottom to top. The high-voltage grid 5 with attached electrodes 1 is arranged downstream of the gas flow relative to the grounded plate, that is to say above the plate 4 . The separated droplets and particles fall down on the sleeve 7 in the insert plate 4 after being electrically neutralized.

[0066] The size ratio on the sleeve 7 with a circular cross section is 0.5≤H≤3L, where L=(D s -D nd ) / 2 is the electrode gap between the disc 2 and the inner surface of the sleeve 7, D s is the inner diameter of the sleeve 7, D nd is the outer diameter of the disc 2 . The preferred height of the sleeve 7 is 0.25≦H≦1.5L. The disc 2 is positioned in the sleeve 7 at a degree of (0.25-0.75) H below the air outlet of the sleeve 7 . The disc 2 is preferably positioned at a height of 0.5H. The disk 2 has the shape of a star electrode with a plurality of corona-inducing tips. The circular sleeve can be provided with slots 10 ...

Abstract

Allocation the present invention relates to a wet-type electrostatic ionization level in an electrostatic separating device used for removing conveyed together conveying particles finely distributed in gas from aerosol and gas, wherein, ht e ionization level includes plates connected to ground potentials or related reverse potentials, and the plates are mounted on clean cross sections in flowage channel sections and are provided with a plurality of similar punched holes used for flowing through gas to be cleaned.A high voltage grid is mounted on the clean cross section in the channel section in electrical isolation mode in the downstream of the gas flow and is connected to a high voltage electric potential through a sleeve in the wall body of the channel section. Claviform high voltage electrodes of the number corresponding to that of the punched holes are fixed to the high voltage grid through one end of the high voltage electrodes and are accordingly and similarly extended into the center of the punched holes / nozzles of the plates through free end thereof, wherein, one the free end, similarly, discs made of electric conducting materials are arranged centrally in the mode that the discs are parallel to the plates but do not contact the plates.

Description

technical field [0001] The invention relates to a wet electrostatic ionization stage in an electrostatic separation device for removing from aerosols, gases, particles of the liquid or solid type which are finely distributed in gases and which are transported together. Background technique [0002] A wet electrostatic separator is a device which is installed in a channel section of a gas-conducting channel and separates finely divided solid or liquid particles from a gas / aerosol flow. Such devices are used in very wide work areas. [0003] The separation process for separating finely divided particles from a gas stream consists of the following steps: [0004] electrostatically charging the particles; [0005] Charged particles aggregate on the surface of the agglomerating electrode; [0006] The charged particles are removed from the agglomerating electrodes. [0007] The electrostatic purification of aerosols, that is, finely distributed particles in gases, is usually ...
