Method for improving abrasion resistance of windward end of honeycomb type denitration catalyst unit

The invention discloses a method for improving the abrasion resistance of the windward end of a honeycomb type denitration catalyst unit, and relates to the technical field of denitration catalysts, and the method specifically comprises the following steps: preparing a calcium sulfate/magnesium sulfate mixed solution, heating to a certain temperature, and keeping the temperature; heating the concrete sealing curing agent to a certain temperature and keeping the temperature; vertically inserting the calcined honeycomb type SCR denitration catalyst monomer into the component A mixed solution and the component B mixed solution in sequence, dipping for a certain time, taking out, and airing; and drying in a hot-blast stove after dipping. According to the invention, the concrete sealing curing agent and the calcium sulfate/magnesium sulfate mixed solution react to form a nano-scale calcium-magnesium compound to fill the pore channels at the windward end of the honeycomb type SCR denitration catalyst, so that the a
