Background
At present, boiler equipment in the thermal power industry, the steel industry and the cement industry are all provided with SCR catalysts in denitration devices for removing nitrogen oxides in boiler tail gas. However, in the long-time operation of the boiler, because the flue gas and smoke conditions are severe, the phenomenon of dust deposition or poisoning of the SCR catalyst occurs to a certain extent, so that the denitration performance is gradually reduced, and the operation of the whole unit may be broken down seriously. For a renewable catalyst, the denitration performance of the catalyst is recovered mainly by a catalyst regeneration technology. In the case of a non-regenerable catalyst, the denitration performance is recovered mainly by replacing the catalyst with a new one.
The catalyst regeneration is mainly to soak the catalyst in a solution for a certain time by preparing a medicament solution with a certain concentration, so as to achieve the purpose of cleaning impurities in the catalyst, but the concentration of the medicament solution is lower and lower along with the regeneration process, and when the concentration is lower than a specified range, the medicament solution needs to be supplemented in time to prevent the cleaning effect from being influenced.
