Under the action of the axial thrust of the first spring, the solution starts to flow along the axial direction of the first spring, the convection of the solution is enhanced, effective components in the solution can be uniformly distributed, the insufficient concentration of local agents is avoided, and the insufficient denitration condition is avoided. The valve on the rubber ball is matched with the ejection column, so that the elastic force of the outward ejection of the sliding plate is in a reasonable interval, the abrasion of the contact part of the rubber ball and the sliding plate due to excessive pressure is avoided, the service life of the equipment is prolonged, and the vibration in the operation of the equipment is reduced. Therefore, the industrial waste gas denitration system is useful in the technical field of industrial waste gas treatment devices.
