Improving Efficiency: Nozzle Arrangement

The following illustration shows an example of an array of (flat-spray type) nozzles. Such an arrangement produces a curtain of water. When the spray patterns of these nozzles are set in one continuous line they overlap each other, which results in uneven distribution. Therefore, it is better to offset the spray patterns (as the illustration below indicates). This avoids interference between the streams and a relatively good distribution is obtained. When the object onto which a nozzle is spraying liquid is moving continuously, washing efficiency can, on occasion, be improved by maintaining the stream at an angle of attack* of 15 degrees to the target.
