[0025] The input end shell 2 and the output end shell 3 are respectively sealingly sleeved and arranged at the axial two ends of the main shell 1, a gas inlet 21 is arranged on the input end shell 2, and a gas outlet 31 is arranged on the output end shell 3.

[0026] The main shell 1 is obliquely installed from one side of the input end shell 2 to one side of the output end shell 3, and the specific inclination angle a is 1.5 degrees. Here, 1.5 degrees is taken as an example, and the value can be changed according to requirements, and can be any value between 1-5 degrees. Different from the traditional integrated structure, the technical scheme adopts the main shell 1 to install the furnace tubes 4, and the input end shell 2 and the output end shell 3 are arranged at the two ends to respectively input and output gas. This structure shortens the length of the main shell 1 where the furnace tubes 4 are arranged. When installing, it is beneficial to adjust the installation angle of the main shell 1 according to requirements, the input end shell 2 and the output end shell 3 are sleeved at the two ends of the main shell 1, and then the internal refractory cast material 5 and the nails 51 are used for structural fixation. This fixing process is more conducive to adjusting the specific installation parameters of the main shell 1, the length can be flexibly adjusted, the installation and production precision requirements of the equipment are greatly reduced, and the practicability is high. The nails 51 can be selected in T, V and Y structures according to different positions and requirements, which are not described in detail here and are uniformly described as nails 51.

[0027] When installing, referring to Figure 3 (taking one side of the input end shell 2 as an example), due to the flexible installation structure of the refractory cast material 5 and the nails 51, the input end shell 2 and the output end shell 3 are coaxially installed with the main shell 1, or the input end shell 2 and the output end shell 3 are non-coaxially installed with the main shell 1; as long as the main shell 1 is at the corresponding inclination angle, it can be ensured to meet the requirements.
