Background
The tower equipment is widely applied in the production industries of chemical engineering, petrochemical industry and the like, and mainly performs unit operations such as rectification, absorption, desorption, humidification and cooling of gas and the like. The tower equipment is divided into a plate tower and a packed tower according to different internal component forms, and compared with the packed tower, the plate tower has the advantages of large processing capacity, low resistance energy consumption, superior anti-blocking performance, low manufacturing cost and the like.
The tower plate is a core component in the plate tower equipment and is a main place for fully contacting gas (steam) liquid or liquid-liquid two phases, so as to achieve the purpose of heat transfer and mass transfer between the two phases.
