The nitrogen drying device for the clean nitrogen system comprises a shell and a tank body, the tank body is welded to the center of the interior of the shell, partition plates are longitudinally welded to the two sides of the interior of the shell, a sliding groove is longitudinally formed in the front of the position between the partition plates and the shell, damping strips are pasted to the two sides of the inner wall of the sliding groove, and the damping strips are welded to the inner wall of the shell. A sliding block is movably connected to the center of the interior of the sliding groove. According to the nitrogen drying device for the clean nitrogen system, the movable block is inserted in the arc-shaped sliding way, the movable block is shifted along the arc-shaped sliding way, the movable block can be locked and fixed through a positioning bolt after being aligned with the movable block and a screw hole, the position of the shifting block is adjusted along the sliding groove exposed in front of the partition plate, and under the limitation of damping strips above the inner walls of the two sides, the movable block is separated from the partition plate. The problem that the first hose and the second hose are twisted or broken due to lack of support when nitrogen is conveyed is avoided, and the problem that the position of the air inlet and outlet pipe is fixed is solved.

The application provides a mixer of a U-shaped post-processing device, which optimizes the structure of the mixer, further prolongs the mixing stroke of the mixer, accelerates the rotating speed of the airflow, makes the urea and ammonia fully react, and reduces the risk of urea crystallization; an air inlet guide plate is arranged vertically at an air inlet; the airflow entering from the air inlet is divided into two airflows by the air inlet guide plate and enters the airflow channel between the inner cylinder and the outer cylinder; a channel separation plate is arranged in the airflow channel; the air inlet guide plate extends into the airflow channel; the air inlet guide plate and the channel separation plate separate the airflow channel into two parts; the inner cylinder is provided with a rotating flow fin, and a gap is left between the rotating flow fin and the outer cylinder; the inner cylinder is provided with an airflow inlet corresponding to the rotating flow fin; the inner cylinder is provided with a urea airflow inlet corresponding to the channel separation plate; and the outer cylinder is provided with a urea nozzle facing the urea airflow inlet.
