Description

Technical Field

[0001] The invention belongs to the technical field of catalyst transportation, and in particular relates to an SCR catalyst damping device and a transportation device. Background Art

[0002] At present, most of the domestic thermal power plants are equipped with SCR denitration devices, and the SCR catalyst plays an important role in the SCR denitration device. SCR catalysts are mainly divided into honeycomb type and plate type, and separate catalyst modules are used in the transportation process. The catalyst module of the honeycomb catalyst is composed of 72 catalyst units assembled and then loaded into an iron frame. The catalyst unit is mainly fixed inside the iron frame by two methods: one is to insert sealing cotton into the gap between the units to increase the friction between the units and the inner wall of the iron frame; the other is that there are many ribs at the bottom of the iron frame to support the units. Each catalyst module of the plate catalyst is composed of two or three layers of boxes, and each box is loaded with dozens of plate catalysts.

[0003] The transportation process of new catalysts leaving the factory and the transportation process of in-service catalysts returning to the power plant after regeneration in the regeneration plant are both transported by trucks on roads. However, there are some problems with truck transportation: uneven roads can easily cause the SCR catalyst to shake violently; sudden braking or sharp turns of the truck can cause the catalyst to shake left and right and move. For new catalysts, their mechanical strength is high, so this situation has little effect on them. However, for regenerated catalysts, they have been running in the SCR denitration reactor for several years, and their mechanical strength has decreased. Catalyst regeneration can only restore their physical and chemical properties, and it is impossible to improve their mechanical strength. Therefore, the bumps of long-distance transportation back and forth will have a great impact on them, which may cause individual catalyst units in the honeycomb catalyst module to sink, or cause some units in the honeycomb catalyst module to be damaged, or cause the catalyst on the plate catalyst to peel off from the substrate.

[0004] However, there is no special shock-absorbing method for SCR catalyst transportation. The same shock-absorbing method as other cargo transportation is used, which is to place wood blocks and cotton pads at the bottom of the catalyst module to reduce the impact of road bumps on the catalyst. Therefore, in view of this situation, it is urgent to develop a simple, efficient, safe and reliable SCR catalyst shock-absorbing device and transportation device to meet actual use needs.

[0031] like Figure 1 The SCR catalyst damping device shown includes a base 21 and a plurality of damping units 22 arranged on the base. The plurality of damping units 22 are distributed along the front-rear direction of the base 21, and two are shown as an example.

[0032] like Figure 2 and Figure 3 As shown, the shock absorbing unit 22 includes a boss 221, a baffle 222, a first shock absorber assembly 223, a support plate 224 and a second shock absorber assembly 225. The boss 221 is fixedly arranged on the base 21, and the baffle 222 is distributed on the front side, rear side, left side and right side of the boss 221. One end of the first shock absorber assembly 223 is connected to the boss 221, and the other end of the first shock absorber assembly 223 is connected to the baffle 222. There is no direct fixed connection relationship between the baffle 222 and the base 21; the support plate 224 is located above the boss 221, and one end of the second shock absorber assembly 225 is connected to the boss 221, and the other end of the second shock absorber assembly 225 is connected to the support plate 224.

[0033] In this embodiment: the first shock absorber assembly 223 includes a first front shock absorber assembly 2231, a first rear shock absorber assembly 2232, a first left shock absorber assembly 2233 and a first right shock absorber assembly 2234, one end of the first front shock absorber assembly 2231 is connected to the front side surface of the boss 221, one end of the first rear shock absorber assembly 2232 is connected to the rear side surface of the boss 221, one end of the first left shock absorber assembly 2233 is connected to the left side surface of the boss 221, and one end of the first right shock absorber assembly 2234 is connected to the right side surface of the boss 221; the first front shock absorber assembly 2231, the first rear shock absorber assembly 2232, the first left shock absorber assembly 2233 and the first right shock absorber assembly 2234 all include multiple shock absorbers, and the multiple shock absorbers are evenly distributed, and all use hydraulic shock absorbers of the same specifications.

[0034] The second shock absorber assembly 225 includes a plurality of shock absorbers, which are evenly distributed and all adopt hydraulic shock absorbers of the same specification.

[0035] The thickness of the baffle 222 is 5-20 mm, and the thickness of the baffle 222 can be adjusted according to the size of the SCR catalyst module 3 placed on the support plate 224. The baffle 222 extends in the up-down direction to block the SCR catalyst module 3 placed on the support plate 224.

[0036] like Figure 4 As shown, the SCR catalyst module 3 is placed on the support plate 224. The SCR catalyst module 3 includes an iron frame 31 and ribs 32. The upper part of the baffle 222 is arranged in the inner cavity of the iron frame 31 and forms a gap with the inner cavity of the iron frame 31. Since there is a certain deviation in the size of the iron frame 31 of different SCR catalyst modules 3, the thickness of the baffle 222 can be adjusted to ensure that the gap between the inner cavity of the iron frame 31 and the baffle 222 is reasonable; the ribs 32 are arranged inside the iron frame 31 and are located on the support plate 224. The support plate 224 can simultaneously support the ribs 32 and the catalyst unit body inside the iron frame 31 to prevent the catalyst unit body from sinking during transportation.

Specifically, a groove or threaded hole is opened on the transport vehicle 1, and the base 21 of the damping device 2 is arranged in the groove of the transport vehicle 1 or connected to the threaded hole of the transport vehicle 1 by bolts.

[0038] Embodiment 1:

[0039] This embodiment uses two shock-absorbing units 22, the size of the base 21 is 1910*970mm, the two shock-absorbing units 22 are symmetrically distributed along the center line of the front-to-back direction of the base 21, the boss 221 is fixedly set on the base 21, the size of the boss 221 is 550*550mm*50mm, the baffle 222 is distributed on the front, rear, left and right sides of the boss 221, and the size of the baffle 222 is 650*130*20mm.

[0042] When this embodiment is used:

[0043] A groove is provided on the body of the transport vehicle 1, the base 21 of the shock absorber 2 is arranged in the groove, and the SCR catalyst module 3 is placed on the support plate 224 of the shock absorber 2. During transportation, when there is a bumpy situation, the SCR catalyst module 3 placed on the support plate 224 will bump up and down, and at this time the second shock absorber assembly 225 starts to work to offset the vibration, thereby playing a role of shock absorption; when there is a sharp turn, the SCR catalyst module 3 will contact the baffle 222, and at this time the first front shock absorber assembly 2231 or the first rear shock absorber assembly 2232 starts to work to offset the centrifugal force, thereby playing a role of shock absorption; when there is a sudden acceleration or sudden braking situation, the SCR catalyst module 3 will contact the baffle 222, and at this time the first left shock absorber assembly 2233 or the first right shock absorber assembly 2234 starts to work to offset the impact force, thereby playing a role of shock absorption.

[0044] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
