Abstract:
A method and apparatus for removing nitrogen oxides from gas streams, includes introducing a to-be treated gas stream into a gas-solid reaction column, and introducing ferric chloride solid particles into the gas-solid reaction tower at the same time. The nitrogen oxides in the gas streams undergo gas-solid chemical adsorption reaction with the ferric chloride solid particles to form solid products and are removed, and thereby purifying the gas.

Claim (Index 12):
A gas-solid reaction column for removing nitrogen oxides from a gas stream comprising:\n a column body ( 4 ); a lower portion of said column body ( 4 ) including a gas inlet ( 1 ); an upper portion of said column body ( 4 ) including a gas outlet ( 6 ) and a solid particle inlet ( 3 ); a bottom of said column body ( 4 ) includes a solid particle discharge port ( 9 ); said gas inlet ( 1 ) is communicated with the gas outlet ( 6 ) through a gas-solid reaction zone ( 12 ); and, the solid particle inlet ( 3 ) is communicated with the solid particle discharge port ( 9 ) through the gas-solid reaction zone ( 12 ) and through the solid particle recovery zone ( 13 ).
