DETAILED DESCRIPTION

[0017] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0018] Please refer to Figures 1-4A tail gas treatment structure for asphalt modification includes a tower body 1. An air inlet 2 is provided on the lower outer side of the tower body 1. A pump box 3 is installed on the other side of the bottom of the tower body 1. A water supply pipe 4 is installed on the upper end of the pump box 3. The water supply pipe 4 extends upward and is connected to one end of the main pipe 801 of the spraying mechanism 8 inside the tower body 1 through a pipe connector 401. An exhaust port 5 is provided on the top of the tower body 1. A grid 6 is fixedly installed on the lower part of the tower body 1. An electric rotating roller 7 is installed on the upper surface of the grid 6.

[0019] The tower body 1 has a cleaning window 101 on one side of its upper part. The cleaning window 101 has a through hole for the main pipe 801 to slide tightly. The cleaning window 101 is connected to the tower body 1 by a locking piece 102 so that the spraying mechanism 8 can be removed from the cleaning window 101 for cleaning.

[0020] The main pipe 801 has multiple branch pipes 802 symmetrically connected at its lower part via rotary joints 803. Multiple spray heads 804 are installed at the bottom of each branch pipe 802 so that the main pipe 801 can move to drive the branch pipes 802 to rotate and move.

[0021] The tail end of the branch pipe 802 is rotatably connected to the slider 806 via a sliding sleeve connector 805, and the branch pipe 802 can slide within the sliding sleeve connector 805 and rotate accordingly.

[0022] The height of the slider 806 is lower than the height of the upper edge of the cleaning window 101. The top of the slider 806 is fitted with a slide rail 807, and both ends of the slide rail 807 are fixed to the inner wall of the tower body 1, so as to facilitate the sliding disassembly of the spraying mechanism 8 from the cleaning window 101.

[0023] Working principle: When maintaining and disassembling the cleaning equipment, first remove the locking plate 102 and the water pipe 4 and open the cleaning window 101. Then, drag the main pipe 801 out of the cleaning window 101. At the same time, the slider 806 moves along the slide rail 807, which in turn drives the sliding sleeve connector 805 to move. At this time, under the constraint and cooperation of each connector, the rotary joint 803 of the branch pipe 802 and the main pipe 801 rotates accordingly. The branch pipe 802 slides inside the sliding sleeve connector 805, and the sliding sleeve connector 805 also rotates accordingly. The spraying mechanism 8 rotates and retracts inward as a whole, and is finally disassembled through the cleaning window 101. When the equipment is working normally for exhaust gas treatment, the electric rotating roller 7 rotates intermittently at a slow speed, which in turn drives the packing material to move relative to each other, so as to maintain the permeable gap and optimize the contact area with the asphalt modified exhaust gas.
