How to install the packing in the tower?

 

The packing is divided into random tower packing and structured packing. What should be paid attention to when installing random packing? It is estimated that many people are not very clear.

 

The stacking of bulk packing is generally not affected by the ellipticity of the tower. In order to facilitate the stacking of random packing into the tower, it is generally placed in a random pile. The recommended error of the conventional random packing tower can be found in the corresponding standard. Generally, after the design is completed according to the standard, the manufacturing and parameters of the packing are also provided by the manufacturer. Sometimes the purchased random packing needs to be processed before use.

 

 There are two methods for loading random packing in the tower: wet loading and dry loading. The so-called wet loading is to fill the tower with water (or process liquid) first, and then load the packing tower packing. This method has a large and uniform bed void ratio, and at the same time can prevent the collision between fragile packings and damage to the packing ring. It is widely used for the loading of ceramic packing, glass ring packing, etc.

 

Dry loading is a method of stacking the packing directly on the support plate, which is widely used for the loading of metal packing and plastic packing. Dry loading is simpler than wet loading, but the porosity of the bed is smaller than that of wet loading.

 

 Whether dry loading or wet loading, it is most important to ensure that the packing layer has a uniform porosity. To this end, it is important to select the reverse loading method according to the specific technical requirements of the packing tower.

 

 Generally speaking, the installation of random packing is that after the packing is introduced into the tower through the inverted cone, it is first filled from the surroundings of the tower cross section to the center. After one layer is filled, the second layer is filled from the center to the surroundings, and so on. Each layer must be leveled once, and this step is especially necessary for large packed towers. When leveling, people should step on the wooden board and avoid direct contact with the packing. The quality of random packing (whether the bed gap is uniform or not) is directly related to the fluid mechanics and mass transfer separation performance of the packed tower. Therefore, it is necessary to operate according to the regulations when loading. more information in website : www.chinachemicalpacking.com    office@chemshun.com
