Description

Technical Field

[0001] This utility model relates to the field of denitrification catalyst production and storage technology, and in particular to a honeycomb denitrification catalyst storage and transportation device. Background Technology

[0002] Nitrogen oxides (NO) X Nitrogen oxides (NOx) are among the pollutants that cause air pollution problems such as acid rain, smog, and ozone depletion. They mainly originate from thermal power plants, steel mills, glass factories, and cement kilns. Due to their stable chemical properties and poor water solubility, they are difficult to remove and are therefore a key target for pollution control. Currently, the main method for controlling NOx is selective catalytic reduction (SCR) denitrification technology, which uses ammonia to catalytically reduce NOx. X It decomposes into N2 and H2O, thereby reducing NO. X Emission concentration.

[0003] The quality of the catalyst is crucial to this technology. Honeycomb denitrification catalysts, as a type of catalyst, possess characteristics such as high efficiency, durability, applicability, and economy. On one hand, in terms of physicochemical properties, honeycomb denitrification catalysts have a large geometrical surface area, which is beneficial for increasing the contact area between flue gas and the catalyst, thereby improving catalytic efficiency. The preparation process typically involves high-temperature calcination, resulting in a low thermal conductivity coefficient, making it more resistant to high-temperature environments and exhibiting good thermal stability, chemical stability, and wear resistance. On the other hand, in terms of design efficiency, the design length of honeycomb catalysts is easy to control, and their relatively light weight meets the requirements of different operating conditions, reducing the need for support structures for the catalyst itself and the load-bearing requirements of equipment, making installation and transportation easier. Furthermore, under the same operating conditions and dosage, honeycomb catalysts have a more uniform gas flow field, longer replacement cycles, and relatively lower operating and maintenance costs. Therefore, honeycomb catalysts are widely used in thermal power and non-electric power industries.

[0004] The largest honeycomb denitrification catalyst currently manufactured has a size of 1360*150*150mm. 3 Currently, the storage and transportation devices for backup and sampling unit honeycomb catalysts are relatively simple and lack safety, mostly using cardboard boxes, plastic and metal packaging, or custom-made wooden crates. Cardboard boxes have poor load-bearing capacity, are easily deformed, and are often filled with soft foam, making the catalyst even more fragile during transportation and unable to meet testing requirements. Plastic and metal packaging is brittle, has high manufacturing costs, requires repeated transportation and reuse, and is inconvenient and costly to transport. Custom-made wooden crates have high material consumption, long customization cycles, cumbersome operation and installation, and are susceptible to moisture damage during storage due to the variable size of the honeycomb catalyst.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown:

[0033] A honeycomb denitrification catalyst storage and transportation device includes a six-sided box structure consisting of a bottom plate 1, a cover plate 2, two end plates 3 and two side plates 4.

[0034] Two end plates 3 are mounted opposite each other on the base plate 1, and two side plates 4 are mounted opposite each other on the base plate 1.

[0035] The intersecting edges of the base plate 1, cover plate 2, end plate 3 and side plate 4 are connected by L-shaped corner brackets 5, which are equipped with connecting screws.

[0036] The dimensions of L-shaped corner bracket 5 are (50+50)*50*5mm, and the screw length is not less than 5mm.

[0037] In this embodiment, the end plate 3 is a long substrate 31, and the cover plate 2 is a long substrate 31.

[0038] Side plate 4 is a short substrate 32.

[0039] The long substrate 31 has dimensions of 1130mm in length, 180mm in width, and 50mm in thickness, and the short substrate 32 has dimensions of 180mm in length, 180mm in width, and 50mm in thickness.

[0040] The box structure has a shock-absorbing layer 7 laid on the bottom plate 1. The shock-absorbing layer 7 is made of rigid damping cotton with a thickness of 10mm. The box structure also has a moisture-proof membrane 9 covering the outside of the honeycomb denitrification catalyst 8. The moisture-proof membrane 9 is made of polytetrafluoroethylene and has a thickness of 5mm.

[0041] A support 10 is installed at the bottom of the base plate 1. The lower base of the support 10 is 50mm long, the upper base is 80mm long, and the height is 40mm.

[0042] When using the catalyst, determine the specific dimensions of the housing based on the dimensions of the catalyst 8. If the length of the catalyst 8 is no more than 1000mm, then the housing dimensions are 1130*280*280mm. 3 .

[0043] The end plate 3 and side plate 4 are installed onto the bottom plate 1 using L-shaped corner brackets 5 and screws, forming a five-sided open box structure. The honeycomb denitrification catalyst 8 is wrapped with a moisture-proof film 9, and rigid shock-absorbing cotton is placed in the box. Then, the honeycomb denitrification catalyst 8 is placed into the box, and the cover plate 2 is installed onto the box using L-shaped corner brackets 5 and screws, forming a single honeycomb denitrification catalyst 8 container.

[0044] A rotating hinge 6 is installed near the side edge of the cover plate 2, and the pivot length of the rotating hinge 6 is 100mm. If there are multiple single honeycomb denitrification catalyst 8 containers, the multiple single honeycomb catalyst 8 containers are connected and fixed by the rotating hinge 6, which facilitates overall stacking and transportation management.

[0046] like Figure 3 and Figure 4 As shown, in this embodiment, the end plate 3 is composed of a long substrate 31 and a short substrate 32, and the cover plate 2 is composed of a long substrate 31 and a short substrate 32.

[0047] The long substrate 31 and the short substrate 32 are connected by a flat angle bracket 11 and a U-shaped nail 12. The flat angle bracket 11 is provided with screws for connection, and the U-shaped nail 12 is provided at the top and bottom of the joint.

[0048] like Figure 5 and Figure 6As shown, the base plate 1 is a telescopic structure. The base plate 1 includes a fixed plate 13 and a movable plate 14.

The electric push rod 16's wires, power supply equipment, and operation buttons can be installed on the outside of the box.

[0049] A guide post 17 is installed on the end face of the movable plate 14 near the fixed plate 13. A guide groove 18 corresponding to the guide post 17 is opened on the fixed plate 13. The guide post 17 extends into the guide groove 18 and is slidably connected to the guide groove 18.

[0050] A flexible moisture-proof cloth 15 is provided at the joint between the fixed plate 13 and the movable plate 14. The flexible moisture-proof cloth 15 is corrugated to ensure that the flexible moisture-proof cloth 15 maintains a stable shape after shrinking and is easy to stretch again, while preventing moisture from the bottom of the box from entering the box.

[0051] In this embodiment, the support 10 can be replaced with a self-locking caster. When the base plate 1 needs to be extended, the locking mechanism of the caster at the bottom of the moving plate 14 is opened to ensure that the moving plate 14 can move stably and reduce the extension resistance.

[0052] Additionally, a placement groove corresponding to the casters can be provided on the top surface of the cover plate 2 to facilitate the limiting of the casters at the bottom of the upper box when multiple single honeycomb denitrification catalyst 8 containers are stacked.

[0053] When using the catalyst, determine the specific dimensions of the housing based on the dimensions of the catalyst 8. If the length of the catalyst 8 is greater than 1000mm and less than or equal to 1180mm, then the housing dimensions are 1310*280*280mm. 3 .

[0054] Using flat angle brackets 11, screws, and U-shaped nails 12, the long substrate 31 and short substrate 32 are assembled into end plate 3 and cover plate 2. The electric push rod 16 is activated to extend the bottom plate 1 to a length of 1310mm. Next, L-shaped angle brackets 5 and screws are used to install the end plate 3 and side plate 4 onto the bottom plate 1, forming a five-sided uncovered box structure. A moisture-proof membrane 9 is used to wrap the honeycomb denitrification catalyst 8. Rigid shock-absorbing cotton is placed inside the box, and then the honeycomb denitrification catalyst 8 is placed inside. The cover plate 2 is then installed onto the box using L-shaped angle brackets 5 and screws, forming a single honeycomb denitrification catalyst 8 container.

[0056] like Figure 7 and Figure 8 As shown, the end plate 3 consists of a long substrate 31 and two short substrates 32, and the cover plate 2 consists of a long substrate 31 and two short substrates 32.

[0057] The long substrate 31 and the short substrate 32 are connected by a flat angle bracket 11 and a U-shaped nail 12. The two short substrates 32 are connected by a flat angle bracket 11 and a U-shaped nail 12. The flat angle bracket 11 is provided with screws for connection.

[0058] When using the catalyst, determine the specific dimensions of the housing based on the dimensions of the catalyst 8. If the length of the catalyst 8 is greater than 1180mm and less than or equal to 1360mm, then the housing dimensions are 1490*280*280mm. 3 .

[0059] Using flat angle brackets 11, screws, and U-shaped nails 12, the long substrate 31 and short substrate 32 are assembled into end plate 3 and cover plate 2. The electric push rod 16 is activated to extend the bottom plate 1 to a length of 1490mm. Next, L-shaped angle brackets 5 and screws are used to install the end plate 3 and side plate 4 onto the bottom plate 1, splicing them to form a five-sided open box structure. The honeycomb denitrification catalyst 8 is wrapped with a moisture-proof film 9, and rigid shock-absorbing cotton is inserted into the box. Then, the honeycomb denitrification catalyst 8 is placed into the box, and the cover plate 2 is installed onto the box using L-shaped angle brackets 5 and screws, forming a single honeycomb denitrification catalyst 8 container.

[0060] The dimensions of the housing of this utility model can be adjusted according to the size of the catalyst.
