The invention discloses a waste
flue gas denitration
catalyst regeneration method, and belongs to the field of
air pollution control. The method comprises the following steps: (1) removing dust through vacuum adsorption; (2) spray-cleaning and cleaning using a high-pressure spray gun; (3) washing with deionized water after ultrasonic cleaning; (4) draining off after acid
pickling; (5) soaking with an activation solution, wherein the activation solution is an
aqueous solution of a precursor of V2O5-WO3 or V2O5-MoO3, the weight percentage of
metal oxides in the V2O5-WO3 activation solution is as follows: 0.8-5.0% of V2O5, 0.3-1.0% WO3 and the balance of water, the weight percentage of
metal oxides in the V2O5-MoO3 activation solution is as follows: 0.8-5.0% of V2O5, 0.15-1.0% of MoO3 and the balance of water; (6)
drying and calcining. The invention also discloses waste
flue gas denitration
catalyst regeneration equipment which includes a tracked conveying device, a spray cleaning device, an ultrasonic cleaning tank, a deionized water cleaning device, a
pickling tank, a drain basket, an activation tank, a rail transport device, a
tunnel kiln and a tunnel calciner, which are sequentially arranged.
