Electrostatic demisting method for tail gas of phosphoric acid production

摘要: The invention discloses an electrostatic demisting method for tail gas of phosphoric acid production. comprises the following steps of: delivering to a bottom air chamber equipment by adopting positive pressure draught fan or negative fan, after is cooled temperature less than equal 50 DEG C; making pass through high voltage static field generated 30 70kV high-voltage constant current DC power supply and ionizing gas; molecules form ions, quickly absorbing anode tube deposition so as neutral molecular drops; drops flow downward diluted tank along obtain reclaimed acid; releasing purified from port top. content production reduced be lower 1PPM more 50PPM demisting, reclamation rate improved 0.50 percent. solves problem environmental pollution in production, effectively protects environment factories surroundings, improves economic social benefit.
