Abstract
This invention is a combination spray nozzle and throttle valve referred to as a nozzle valve. Its primary use is to characterize the spray pattern and vary the flow rate of the spray in a reversed jet installation where rate of flow in the spray must be varied to meet process requirements. Energy for contacting liquid and gas phases in a reversed jet installation comes from the kinetic energy of the jet spray. The improvement a nozzle valve provides is that the kinetic energy of the spray from the nozzle valve is substantially equal to the potential energy of its supply liquid at all flow rates. A number of spray characterizations are available to match the nozzle valve to a particular reversed jet installation. By these improvements the energy to the contact zone of a reversed jet system can be maintained at a constant maximum value on a unit mass flow basis over a wide range of spray flow rates.
