Embodiment Construction
[0026] The present invention is described in detail as follows with reference to accompanying drawing:
[0027] As shown in the figure, A is the first adsorption tower, and B is the second adsorption tower. 1 is an air filter, 2 is a blower, 3 is a heater, and 4 is an induced draft fan.
[0028] absorb
[0029] After the mixed gas to be treated is washed with water to remove dust and cooled, it enters the absorption tower from the bottom under the condition of normal pressure and not higher than 60°C (normal temperature to 60°C), and the hydrogen peroxide is sprayed from the top of the tower to combine with the SO in the mixed gas 2 / NO x The reaction occurs, and the generated acid liquid is discharged from the bottom of the tower into the neutralization tower, and the tail gas after absorption is discharged from the top of the tower.
[0030] neutralize
[0031] The acid liquid discharged from the absorption tower reacts with ammonia water in the neutralization tower to o...
