Abstract
A method and device for removing, deodorizing and purifying odor, smoke and harmful substances from exhaust gas or flue gas employs a water solution containing hypohalogen acid such as hypochlorous acid soda, an alkaline electrolyte such as potassium hydroxide or sodium hydroxide and a saline electrolyte such as sodium chloride, potassium chloride, sodium bromide or potassium bromide which is electrolyzed to produce an electrolytic water solution which is fed to a deodorizing tower and brought into contact with exhaust gas or flue gas to remove odor, smoke and harmful substances in the exhaust gas or flue gas.
Claims15
A method for deodorization and purifying exhaust gas or flue gas, comprising the steps of:
- electrolyzing an electrolytic water solution that is a mixture of an alkaline electrolyte group and a neutral salt electrolyte group in an electrolytic reactor;
- and
- bringing the electrolyzed electrolytic water solution into contact with the exhaust gas or flue gas.
A deodorization and purification device for exhaust gas or flue gas, comprising:
- an electrolytic reactor for electrolyzing an electrolytic water solution that is a mixture of an alkaline electrolyte group and a neutral salt electrolyte group;
- an absorber;
- a water circulation path;
- a circulation pump for feeding electrolyzed electrolytic water solution generated in the electrolytic reactor to the absorber via the water circulation path;
- and
- a shower spray for introducing a shower of electrolyzed electrolytic water solution to the absorber.
The device as claimed in claim, wherein the electrolytic reactor includes an anode formed of an electrically conductive metal with an electrically conductive ceramic or a vapor deposited or thermal sprayed film of an electrically conductive ceramic, or a vapor deposited or thermal sprayed film of diamond formed on a surface of the electrically conductive metal, and a cathode formed of an electrically conductive metal.
