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 8):
A method according to  claim 1 , characterized in that said gas-solid reaction column comprises:\n a column body ( 4 ); a lower portion of said column body ( 4 ) includes a gas inlet ( 1 ); a middle of the column body ( 4 ) includes a solid particle port ( 3 ); a gas flow distributor ( 2 ) is disposed in the column body ( 4 ) above the gas inlet ( 1 ); an upper portion of the column body ( 4 ) includes a connecting pipe ( 5 ) communicated with a gas-solid separator ( 7 ); the upper portion of the gas-solid separator ( 7 ) includes a gas outlet ( 6 ); a lower portion of the gas-solid separator ( 7 ) includes a solid particle discharge port ( 9 ) and a solid particle return port ( 8 ); the solid particle return port ( 8 ) communicates with the column body ( 4 ); and the column body ( 4 ) includes an inspection port ( 10 ) and a bottom solid particle discharge port ( 11 ).
