Devices, systems and methods for mixing and/or introducing agrochemicals

A mixer system for effectively combining gaseous agrochemical such as a fumigant and a water source for use in irrigation infrastructure, comprising:

• a flow pathway adapted to interconnect a water source at a water receiving end and irrigation infrastructure at a delivery end thereof, the receiving end of the mixer system adapted to receive a flow of incoming water from the water source in a waterflow pathway;
• a mixing chamber in the waterflow pathway downstream from the water receiving end, the mixing chamber having:
• an inlet for receiving flow of water from the waterflow pathway;
• an at least one delivery point for receiving the gaseous agrochemical into the mixing chamber to interact with the water from the water source;
• an outlet for egress of the agrochemical and water mixture;
• a flow restriction component at or proximal the outlet of the mixing chamber for restricting outflow of the water-agrochemical mixture at the outlet of the mixing chamber, and
• an agrochemical injector defining an agrochemical pathway, the ably cooperative with the at least one delivery point for injecting a gaseous injector agrochemical into the mixing chamber under pressure;
• wherein the flow restriction component is adapted to generate backpressure and turbulence in the water and gaseous agrochemical combination in the mixing chamber, and thereby initiate a distribution of fine bubbles of the gaseous agrochemical in water in the mixing chamber;
• and wherein the distribution of fine bubbles improves mixing of the gaseous agrochemical and irrigation water and flows, effective for consistent distribution of agrochemical applied to a crop by the irrigation infrastructure, and
• wherein the injector includes:
• an injector input for receiving the agrochemical;
• a connection component for sealably securing the injector to the mixing chamber at the delivery point;
• an injector output for introducing the agrochemical into the mixing chamber, the injector output including a sintered diffuser for introducing the agrochemical into the liquid flowing within the mixing chamber, wherein in operation the sintered diffuser extends sufficiently within the mixing chamber to be substantially submerged in the water as it flows in the mixing chamber, and wherein the sintered diffuser bas a media grading of about 1 μm to about 80 μm in diameter to enable production of agrochemical bubbles in the liquid having a diameter of about the same dimension;
• and
• a body through which the agrochemical can travel, the body located between the injector input and the injector output.
