[0002] Packed tower is also called packed tower. It is a type of mass transfer equipment commonly used in chemical production. It is mainly composed of a cylindrical tower body and packings stacked in the tower. It is used for absorption, distillation, extraction, etc. The packed tower uses packing as the basic component for gas-liquid contact and mass transfer. The liquid flows from top to bottom in a film-like manner on the surface of the packing, and the gas flows from bottom to top in a continuous phase with the liquid, and mass and heat transfer between the gas and liquid phases are carried out. The component concentration and temperature of the two phases change continuously along the tower height. The existing chemical packed tower has the problem of complex installation.

[0003] Publication number CN218358352U is an air separation refrigeration composite chemical packing tower. Through the setting of the cleaning component, the impurities on the filter plate are cleaned. Specifically, the motor drives the threaded rod to rotate, the threaded rod drives the slider to move, the slider drives the connecting rod to move, and the connecting rod drives the cleaning brush to move, and the filter plate is cleaned. The impurities are cleaned to the place near the second manhole, and then the scraper is pulled by a long rod to discharge the accumulated impurities after cleaning through the second manhole, so as to avoid the problem of clogging of the holes inside the packing tower and improve the efficiency of the operation. However, it still has not improved in terms of installation convenience. Utility Model Content

[0041] How it works

[0042] This easy-to-install composite chemical packing tower,

[0043] During installation, the lower tower body 1 is fixed to the ground, and then the middle tower body 2 is moved to the top of the lower tower body 1 by a tower crane. After positioning, a tool or a motor is used to rotate the rotating head 33 to drive the threaded column 32 to rotate so that it is fixed to the threaded pipe 31, and the convex edge 21 and the concave annular groove 22 are matched to achieve a clamping connection, and then the external pipeline is connected for use;

[0044] A mixture of two or more materials is sent to the packed tower from the feed port. The lighter components are separated on the tower packing layer 6 according to their relative volatility. The heated steam moves upward along the tower, passes through the packing and comes into contact with the liquid material from the top of the tower. The heavy components in the upward material are condensed into liquid and flow downward along the gaps in the packing. The light components in the liquid are vaporized and enter the upper packing layer 6 with the rising steam. In the process of mass transfer, heat is also exchanged. After passing through several packing layers 6, the lighter component product is obtained at the top of the tower, and the heavier component product is obtained in the bottom of the tower.

[0045] When maintenance is required, tools or motors are used to rotate the rotating head 33 to open the gaps between the tower bodies, allowing for convenient dismantling or maintenance. At the same time, an external tower crane is required to be used to increase safety.
