Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb catalyst processing equipment, and more specifically to a cutting and blanking device for honeycomb catalyst wet blanks. Background Art

[0002] In the SCR flue gas denitrification system of a power plant, the catalyst is the most important part. In the SCR denitrification reaction, the catalyst is a substance that prompts the reducing agent to selectively react chemically with nitrogen oxides in the flue gas at a certain temperature. Currently, there are three types of the most widely used denitrification catalysts: honeycomb, plate and corrugated plate. The honeycomb type has become the most important catalyst type due to its high denitrification efficiency, large specific surface area, strong anti-poisoning performance and low cost of use. After the honeycomb catalyst is extruded by the extruder, its humidity is relatively high and it needs to be cut and dried.

[0003] In the prior art, after the honeycomb catalyst is cut into sections, the staff generally transports the honeycomb catalyst to a transfer vehicle, and then moves the transfer vehicle to a drying room for drying. However, there are some problems in its use. The honeycomb catalyst has a high humidity and is therefore heavy. If the staff transports it, not only is the labor intensity high, but the work efficiency is also low, and it is also easy for the honeycomb catalyst to form a plate.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content
