Compact spraying module, system for spraying and controlling a plurality of such modules, and method for controlling modules of such a system

A spraying and control system for the spraying of a liquid in droplet form for the treatment of a target, said spraying and control system comprising:

• a plurality of independent compact spraying modules;
• a separate common reservoir located separate from each compact spraying module;
• a piping for supply of liquid between said common reservoir and each of said independent compact spraying modules;
• and
• a control panel that remotely individually controls each compact spraying module, independently of the other compact spraying modules,
• wherein each of said compact spraying modules has:
• a spraying unit with an exhaust nozzle with an air inlet opening at one of its ends and an air outlet opening at its other end, with said exhaust nozzle surrounding, along its axis, an inner space that contains at least one spraying element creating and propelling droplets in the inner space,
• a fan that can axially generate—in the inner space of the exhaust nozzle—a stream of carrier air around said spraying element to carry toward the target the droplets that are created and propelled in said stream of carrier air in the inner space, and
• a fan drive system for driving said fan,
• wherein each of said compact spraying modules further has:
• a separate liquid supply system that is functionally connected to the piping said liquid supply system including an electric pump, combined with a flow rate sensor, that pushes back, at a controlled variable flow rate, the liquid that comes from said common reservoir, in said piping, and a connecting interface that is provided to receive the liquid that comes from the reservoir of the spraying and control system, and
• a support that keeps the electric pump steady, in proximity to the spraying unit, an electronic control and/or monitoring unit, on an electronic card, provided for the purpose of controlling and/or monitoring the operation of the fan drive system and the liquid supply system by being functionally connected to said drive system and liquid supply system, an individual communication interface for functionally connecting the compact spraying module, directly or indirectly, to the control panel, and an energy supply interface that can be connected functionally to an electrical energy source to supply energy to said compact spraying module,
• such that said control panel can independently control each of said compact modules separately, allowing for independent adjustment of the amount of treatment sprayed on said target.
