摘要:
The invention relates to a wet electrostatic ionising step in an electrostatic deposition device for the purification of an aerosol of a gas from the finely-dispersed particles carried along therewith, comprising a plate connected to an earth potential or a relative counter-potential, arranged over the open cross-section of a flow channel section and a number of similar openings for the throughflow of the gas for purification. A high-voltage grid, arranged downstream in the gas flow with electrical insulation over the open cross-section is connected to a high voltage source via a duct in the wall of the channel section. A number of rod-like high voltage electrodes corresponding to the openings are fixed with the free end thereof to the high-voltage grid and all extend with the free end thereof through an opening/nozzle of the plate. A disc of electrically conducting material sits on each free end, parallel to the plate without contacting the same.
摘要:
The invention relates to an aerosol separator for separating dust aerosol and droplet aerosol, comprising a channel section which has a vertical or steeply inclined axis and contains the aerosol separator, into which waste gas flows from below. Said aerosol separator has at least one end spraying region covering the cross-section of the channel. In said end-spraying region, the through-flowing crude gas or waste gas is subjected to a mist of droplets of a volatile liquid and is guided into the supersaturated wet region. A bundle of tightly packed, similar, straight tubes of process-suitable or process-inert material, extending over the cross-section of the channel, is connected in the direction of flow. The liquid droplets fall on the inside and outside of the tubes of said bundle and flow off in the counter-flow on the outwardly concave surface of the tube bundle, on which they flow off towards the channel wall in a groove surrounding the inner wall of the channel, and are recovered via an outflow opening as a collected liquid containing impurities.
