How should the nozzles of a spray tower be arranged? !

Is it fully covered? How to consider the gas-liquid contact time in spraying? !
It mainly depends on the size of the spraying area and the spray angle design of the nozzles
Well, yes, actually when liquid is sprayed using a nozzle, because of its conical shape, there is a considerable amount of space where the liquid does not come into contact with the gas. So how should we consider the gas-liquid contact time in such cases? !
This depends on the particle size of the liquid being sprayed, as well as the room temperature; the vaporization time needs to be calculated, and space must be reserved for vaporization
By vaporization you mean the cooling tower, right?
Consider using a plug-type nozzle, which sprays the liquid in an umbrella shape, resulting in a relatively better effect
If no distributor is used and nozzles are installed directly, full coverage must be ensured. The angle at which the nozzle sprays needs to be taken into consideration; based on this angle, the installation height of the nozzle should be calculated so that the liquid sprayed covers the entire cylinder. There are samples available for reference regarding these nozzles； As for the gas-liquid contact time you mentioned, it refers to the amount of spray liquid. This requires calculating the spray density based on the specifications of the packing, and then determining the amount of spray liquid needed based on the diameter of the tower.
