Description
Technical Field
The utility model belongs to the technical field of catalyst transportation, and particularly relates to an SCR catalyst damping device and a transportation device.
Background
At present, most of domestic thermal power plants are provided with SCR denitration devices, and SCR catalysts play an important role in the SCR denitration devices. The SCR catalyst is mainly divided into a honeycomb type and a plate type, and a single catalyst module is adopted in the transportation process. The catalyst module of the honeycomb catalyst is formed by assembling 72 catalyst unit bodies and then arranging the assembled catalyst unit bodies in an iron frame, wherein the catalyst unit bodies are mainly fixed in the iron frame by two methods: firstly, sealing cotton is stuffed in the gaps between the unit bodies, so that the friction force between the unit bodies and the inner wall of the iron frame is increased; secondly, there are a lot of fins bottom the chase, is used for supporting the unit body. Each catalyst module of the plate catalyst is composed of two layers or three layers of boxes, and each box is filled with dozens of plate catalysts.
The transportation process of the new catalyst leaving factory and the transportation process of the catalyst in service returning to the power plant after regeneration in the regeneration factory are both carried by truck and road. However, trucking can have some problems: rough road surface easily causes the SCR catalyst to jolt violently; the catalyst is shaken leftwards and rightwards, displaced and the like due to sudden braking or sharp turning of the truck. The mechanical strength of the new catalyst is high, and the situation has little influence on the new catalyst, but for the regenerated catalyst, the mechanical strength of the regenerated catalyst is reduced after the regenerated catalyst is operated in an SCR denitration reactor for several years, the physical and chemical properties of the regenerated catalyst can only be recovered, and the mechanical strength cannot be improved, so that the regenerated catalyst is greatly influenced by the jolt of long-distance transportation, and the phenomenon that individual catalyst unit bodies in a honeycomb catalyst module sink, or the phenomenon that a part of the unit bodies in the honeycomb catalyst module are damaged, or the phenomenon that a catalyst on a plate type catalyst is peeled from a base material can be caused.
However, at present, no damping method specially used for SCR catalyst transportation exists, and the damping method is the same as that used for other cargo transportation, and battens, padding cotton and the like are placed at the bottom of a catalyst module to reduce the influence of bumping on a catalyst in the road. Therefore, in order to meet the current situation, the SCR catalyst damping device and the transportation device which are simple, efficient, safe and reliable to operate are urgently needed to be developed so as to meet the actual use requirements.
