Description

Fluoroplastic pall ring for packed tower Technical Field The utility model relates to the technical field of chemical equipment, in particular to a fluoroplastic pall ring for a packed tower. Background In many technological processes of chemical production, such as rectification, absorption, desorption and the like, a packing tower is an extremely important gas-liquid mass transfer device, and the working principle of the packing tower is that a sufficient contact area is provided for gas-liquid two phases through packing filled in the tower, so that substances are transferred and separated, in the actual operation process of the packing tower, in particular in the case of high gas speed, high liquid speed or solid particle flushing, fluoroplastic pall rings are easy to deform and damage, the deformed pall rings can change the flow paths and distribution states of the gas-liquid, the mass transfer efficiency is reduced, channels in the tower can be blocked by broken pall ring fragments, the pressure drop is increased, even the normal operation of the packing tower can be influenced in severe cases, and the shutdown maintenance and the packing replacement are needed, so that the production cost and the production period are increased. Disclosure of utility model The utility model mainly aims to provide a fluoroplastic pall ring for a packed tower, which can effectively solve the problems in the background technology. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The fluoroplastic pall ring for the packed tower comprises a lower ring body, wherein the inner side of the lower ring body is fixedly connected with a connecting device, the middle part of the upper end of the connecting device is clamped with a butting device, the outer side of the butting device is fixedly connected with an upper ring body, and a fixing ring is jointly and movably connected between the upper end of the connecting device and the lower end of the butting device; The connecting device comprises a first inner rib plate, a clamping groove is formed in the middle of the upper end of the first inner rib plate, and the first inner rib plate is fixedly connected to the inner side of the lower ring body. Preferably, the butt joint device comprises a second inner rib plate, the middle part of the lower end of the second inner rib plate is fixedly connected with a clamping column, and the second inner rib plate is fixedly connected with the inner side of the upper ring body.
