[0002] When the workshop machine equipment is running, the existing waste gas treatment washing tower equipment in the periphery needs to maintain continuous operation and treatment. However, during the operation, when the pressure difference before and after the washing tower reaches a certain pressure difference (due to the high pressure difference of the washing tower, the negative pressure at the workshop machine end is too small, which causes the tower body and the end PP pipe to be easily sucked and collapsed, causing a shutdown accident), it is necessary to stop and check the blockage of the washing tower packing. The current existing cleaning methods are mainly: 1. Stop the equipment to check the internal packing and wash the packing; 2. Check the degree of crystallization and replace the packing; 3. Add a spare washing tower and switch it regularly for maintenance, but these three methods have several problems:

[0003] 1. The cost of equipment downtime is high, which seriously affects the normal production of the workshop;

[0024] The treatment layer 8 filters the pickling mist. The treatment layer 8 is arranged above the two first water pipes 7. It should be noted that after the treatment layer 8 filters the pickling mist, the impurities in the mist will accumulate and crystallize in the treatment layer 8. That is, these crystals cause the pressure difference of the washing tower 1 to be too high, and they need to be cleaned.

[0025] It also includes an installation mechanism, which includes a fixed frame 13 fixedly connected to the inner wall of the washing tower 1, the inner wall of the fixed frame 13 is provided with a first annular groove 14, the inner wall of the first annular groove 14 is slidably connected with an annular frame 15, the upper end of the annular frame 15 is elastically connected to the top of the first annular groove 14 through a plurality of springs 16, the upper end of the annular frame 15 is provided with a second annular groove 17, the side wall of the treatment layer 8 is connected to the bottom of the second annular groove 17 through a plurality of screws 18, so as to facilitate the installation and disassembly of the treatment layer 8.

The operation is fast and convenient, and the use and maintenance costs are very low. The equipment does not need to be shut down, and the treatment layer 8 can be used repeatedly, saving costs. In addition, the crystals will flow out through the drain pipe 4 and be collected thoroughly, effectively avoiding the pollution of the environment by the unorganized diffusion of the crystals, and ensuring that the discharge treatment meets the national standards;

[0033] At the same time, the motor 19 is started to rotate, and then the cross bar 20 drives the two cams 21 to rotate. The two cams 21 will intermittently hit the bottom of the annular frame 15, causing the annular frame 15 to vibrate, vibrating the crystals on the treatment layer 8 and accelerating their falling.
