[0002] The regular flow packed tower is an internationally leading device with high efficiency in desulfurization and dust removal in the current desulfurization process. After nearly 10 years and more than 300 engineering application cases, the regular flow packed tower has been proven to have unparalleled advantages over other tower types in terms of efficient mass transfer and reliable operation. It is widely used in gas purification, coal gas dust removal, flue gas cooling, gas-liquid separation and various harmful gas purification. The regular flow packed tower includes multiple regular flow beds. The flue gas enters the regular flow bed through the diversion system. The dust and SO2 and other pollutants in the flue gas are captured by the liquid film on the surface of the packing balls in the regular flow bed, thereby achieving the purification effect of the flue gas.

[0003] The existing grids used in the fluidized bed need to ensure that the gas can pass through effectively, and the side that is in direct contact with the gas will produce greater corrosion under the influence of flue gas for a long time. Therefore, the grid needs to be replaced or maintained regularly. The existing grids are fixed in the packing tower. Construction personnel need to dismantle and replace the entire grid when entering the tower, which is cumbersome and not conducive to the replacement and maintenance of the supporting grid by maintenance personnel. Summary of the invention

[0008] The bottom of the upper support ring is rotatably connected to a lower support ring, and the bottom end of the lower support ring is fixedly connected to several fixing plates for connecting and fixing the device as a whole, and several fixing plates are provided with fixing holes connected to the tower body.

[0009] Wherein, the bottom of the outer protective grille and the bottom of the inner protective grille are respectively provided with connecting grooves matching the outer grille rods and the inner grille rods, and the outer grille rods and the inner grille rods are slidingly connected with the outer protective grille and the inner protective grille through the connecting grooves.

[0010] The beneficial effect of the utility model is that the extension rod, the support frame and the fixing hole form a component that can ensure the bearing capacity of the outer support ring body and the inner support ring body, and at the same time cooperate with the outer grille rod, the inner grille rod, the outer protective grille and the inner protective grille to directly replace the corroded part, so that the device can directly replace the outer protective grille and the inner protective grille quickly, avoiding the need to separate the device as a whole, thereby improving the maintenance efficiency of the device.
