A kind of continuous pleating equipment and scr plate type catalyst

Abstract

The present invention proposes a continuous crimping device, including a profiling roller, the profiling roller includes a circular arc portion and a profiling portion connected to the circular arc portion, the profiling portion includes a first tooth peak, a second A tooth valley, a second tooth peak, and a second tooth valley, the radius ratios of the arc portion, the first tooth peak, the first tooth valley, the second tooth peak, and the second tooth valley 60:1.5:2.5:2:2. Beneficial effects of the present invention: the first tooth peak, the first tooth valley, the second tooth peak and the second tooth valley are used as the top to reduce the bending radius and offset the position of the center of the circle, effectively solving the problem of the SCR plate catalyst between the first profiling roller and the second tooth valley The deformation "rebound" after the pressing roll leaves, reduces 80% of the springback after pressing, and improves the accuracy of the waveform spacing of the SCR plate catalyst from ±2mm to ±0.5mm, greatly reducing production residues compared with the existing technology The material and production efficiency are improved, and the SCR plate catalyst with the best comprehensive parameters is obtained.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a continuous pleating device and an SCR plate catalyst. Background technique [0002] On July 29, 2011, the Ministry of Environmental Protection officially released the "Emission Standards of Air Pollutants for Thermal Power Plants", which strictly stipulates the emission limits of nitrogen oxides from thermal power plants. Among the various existing denitrification technologies, the ammonia selective catalytic reduction (SCR) method is currently the main denitrification technology for coal-fired power plants due to its high denitrification efficiency, good selectivity, and mature technology. [0003] Catalyst is the key part of SCR denitrification system. At present, SCR denitrification catalyst mainly has three types: honeycomb type, flat plate type and corrugated plate type. The main components of the three types of catalysts are the same as the catalytic reac...

AI Technical Summary

Problems solved by technology

The existing profiling device is stamped and formed by multiple molds, and the resulting corrugated plate is intermittent. The corrugated size accuracy is low, the profiling speed is slow, and the corrugated springback is large, and the size is not easy to control.

At the same time, the existing pressing device hardly considers the impact of the shape formed by the stamping of the flat SCR denitration catalyst on the specific surface area, mechanical strength, production residue and production efficiency.
