Abstract

The invention discloses a preparation method of a denitration catalyst module frame assembly, and relates to the technical field of denitration catalysts. The preparation method comprises the following steps: roughening the surface of a steel plate, then depositing a catalyst material on the roughened surface of the frame steel plate in a coating manner, and drying and roasting to obtain the denitration catalyst module frame assembly. The invention also provides the denitration catalyst module frame assembly prepared by the preparation method, and a denitration catalyst module. According to the invention, the denitration catalyst module frame assembly prepared by the invention can be directly assembled into a honeycomb catalyst module frame through rivets or screws or in a welding manner,and the contact surfaces of catalyst monomers and the frame do not need to be filled with ceramic fiber gaskets and ceramic fiber blankets, so that the pressure difference between the two ends of themodule can be reduced, the catalyst assembly difficulty and labor cost are reduced, and the honeycomb denitration catalyst monomer utilization rate and denitration activity are improved.

Description

technical field [0001] The invention relates to the technical field of denitration catalysts, in particular to a preparation method and application of a denitration catalyst module frame assembly. Background technique [0002] SCR denitrification technology means that under the action of a catalyst, nitrogen oxides are decomposed by NH 3 Reduction to nitrogen reaction. SCR denitrification technology has been widely used in the field of coal-fired furnaces. The current situation of my country's energy structure is more coal, less oil, and less gas, so the pressure on denitrification treatment of coal-fired kilns will become increasingly severe. Relevant standards have increasingly stringent requirements for green development. The main goals of environmental governance at this stage are to strengthen air pollution control and improve environmental quality, and continue to implement total amount control of nitrogen oxides. [0003] As the core component of SCR denitration te...
