Background

The denitration catalyst used in the thermal power station has the problems that after the denitration catalyst is operated for a period of time, the surface area and the performance of the denitration catalyst are reduced due to the accumulation of a large amount of fly ash or other particles, the fly ash can cause the pressure drop of the whole SCR denitration system to be increased, and the device is stopped in severe cases. Therefore, denitration catalysts are usually required to be subjected to regeneration and blockage removal treatment after being used for a period of time, and wet washing (high-pressure water washing or ultrasonic vibration washing) is usually adopted for cleaning pore channel blockage substances of the catalysts at present. However, these wet scrubbing techniques are difficult to wash out the fine fly ash in the catalyst channels because the fine particles adhere tightly to the solid-liquid surface. In addition, the denitration catalyst contains a large amount of sulfate ions, and water is converted into sulfuric acid immediately after entering the catalyst, and such a strongly acidic substance causes corrosion of the substrate of the denitration catalyst and may further cause corrosion of carbon steel equipment of the denitration device.
