Preparation method of denitration catalyst plate, catalyst paste and denitration catalyst plate

Abstract

The invention relates to the technical field of flue gas denitration, and provides a preparation method of a denitration catalyst plate, a catalyst paste and a denitration catalyst plate. The denitration catalyst plate is prepared according to the preparation method, and the preparation method includes placing the catalyst paste and a steel mesh with a first thickness at the entrance of the coating roller gap, and the first thickness is 0.3 mm to 0.5 mm. mm; the coating roller brings the catalyst paste into the steel mesh, and rolls the steel mesh with a preset coating pressure to obtain a denitration catalyst plate with a second thickness, and the second thickness is 0.4 mm ~ 0.6mm. The feature of the present invention is that the catalyst paste can effectively overcome the problem of insufficient adhesion of the paste after the steel mesh becomes thinner, and the preparation method can prepare a denitration catalyst plate with a smaller thickness, without reducing the denitration efficiency , reduce the amount of catalyst paste, and reduce production costs.

Description

technical field [0001] The invention relates to the technical field of flue gas denitration, in particular to a preparation method of a denitration catalyst plate, a catalyst paste and a denitration catalyst plate. Background technique [0002] With the development of modern industrial production and the improvement of living standards, air pollution has become a matter of great concern to people. Flue gas denitrification refers to reducing the generated nitrogen oxides to nitrogen, thereby removing nitrogen oxides in the flue gas, so it can reduce the emission of nitrogen oxides in the flue gas and protect the atmospheric environment. [0003] At present, the most mature flue gas denitrification technology is the SCR (Selective Catalytic Reduction) method, and the catalyst, as the core part of the SCR technology, determines the denitrification efficiency and economy of the SCR system, and its construction cost occupies a large part of the flue gas denitrification project co...

Problems solved by technology

However, in the process of use, not all the coated catalyst pastes play a catalytic role, that is, only a part of the catalyst paste close to the surface can play an effective catalytic role, and most of the catalyst pastes only play the role of filling the skeleton. , which results in a low utilization rate of the catalyst paste, which makes the production cost of the denitrification catalyst higher

However, when a thinner steel mesh is used as the skeleton to make the denitration catalyst plate, the current preparation method of the denitration catalyst plate has the problem of insufficient adhesion of the catalyst paste
