[0022] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for the convenience of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0023] As Figures 1-5 shown, the technical solution of the present utility model provides an SCR catalyst encapsulation module, which includes a module box 1 and an SCR catalyst module 4 encapsulated in the module box 1. The module box 1 includes an upper box body 2 and a lower box body 3, and the upper box body 2 and the lower box body 3 are detachably connected; the SCR catalyst module 4 includes a plurality of SCR catalyst carrier units 5 arranged in a rectangular array, and each SCR catalyst carrier unit 5 includes a plurality of SCR catalyst carriers connected end to end in sequence, and the holes of the plurality of SCR catalyst carriers are aligned with each other.

[0024] The catalyst is encapsulated in the SCR catalyst carrier, and the SCR catalyst carrier is provided with honeycomb-shaped holes, and the gas passes through these holes and is purified. In this solution, the SCR catalyst carriers are connected end to end in sequence to form the SCR catalyst carrier unit 5. As Figure 2 shown in this embodiment, three SCR catalyst carriers form an SCR catalyst carrier unit 5, and a total of four SCR catalyst carrier units 5 are provided. Of course, the quantity can be changed according to actual use requirements. This solution uses the SCR catalyst carrier unit 5 to stack to form a large SCR catalyst module 4 to meet the use requirements. Both the external module box 1 and the internal SCR catalyst module 4 are convenient for industrial production and installation, improving the catalyst encapsulation efficiency and accuracy; at the same time, it is also convenient for later maintenance and overhaul.

[0025] Two adjacent SCR catalyst carriers are detachably connected. One of the SCR catalyst carriers is provided with an insertion piece 6, and the adjacent SCR catalyst carrier is provided with a slot 7, and the insertion piece 6 is inserted into the slot 7. When connecting, insert the insertion piece 6 into the slot 7 of the adjacent SCR catalyst carrier to complete the connection of the two adjacent SCR catalyst carriers. At the same time, the insertion piece 6 and the slot 7 cooperate to play a limiting role, so that the holes of the connected SCR catalyst carriers are aligned with each other to ensure that the gas can pass through the holes smoothly.

[0026] In order to protect the outside of adjacent SCR catalyst carriers, a buffer member 1 is provided between the two SCR catalyst carriers, and a buffer member 2 is provided in the module box 1, so that the SCR catalyst carrier units 5 and the SCR catalyst carrier units 5, as well as the SCR catalyst carrier units 5 and the module box 1 are all softly connected, have a certain buffering effect, and the SCR catalyst carrier units 5 are not easily damaged.

[0027] The first buffer component includes a buffer gasket 8, which separates two adjacent SCR catalyst carrier units 5. The second buffer component includes a buffer gasket 9 embedded in the upper case 2 and a buffer gasket 10 embedded in the lower case 3. The buffer gaskets 9 and 10 cover the inner surfaces of the upper case 2 and the lower case 3, respectively. Furthermore, the first buffer gasket 8, the second buffer gasket 9, and the third buffer gasket 10 are all ceramic fiber gaskets with high-temperature resistance, suitable for use in high-temperature gas environments.

[0028] The upper case 2 and the lower case 3 are both configured as a "冖" type. Ribs 11 are provided on both sides of the upper case 2, and grooves 12 are provided on the upper side of the lower case 3 corresponding to the ribs 11. The ribs 11 are narrow at the top and wide at the bottom, and the two lower sides are configured as arc-shaped structures. The upper case 2 and the lower case 3 can be locked together. The ribs 11 on the upper case 2 are inserted into the grooves 12 on the lower case 3 from one side, and then moved until the upper case 2 and the lower case 3 are aligned. This allows the upper case 2 and the lower case 3 to be connected, that is, the SCR catalyst module 4 is encapsulated. The above-mentioned connection method of the upper case 2 and the lower case 3 facilitates disassembly and maintenance.

[0029] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
