Abstract

A localized product injection system includes a composite boom tube having a carrier fluid passage within a tube body, and at least one injection product passage within the tube body isolated from the carrier fluid passage. A plurality of port stations are provided at locations along the tube body. Each of the port stations includes a carrier fluid outlet port and at least one injection product outlet port. A localized injection interface is coupled at a port station. The injection interface includes a carrier fluid input coupled with the carrier fluid outlet port, and at least one injection product input coupled with the at least one injection product outlet port. The injection interface includes at least one throttling element in communication with the at least one injection product input, a mixing chamber, and an injection port configured for localized coupling and injection to a product dispenser.

First claim

The claimed invention is:

wherein the composite boom tube is divided by partitions into a plurality of isolated passages;
wherein the plurality of isolated passages includes:
at least one passage configured for passage of an injection product; and
at least one passage configured for passage of a carrier fluid;

an input face on the interface body, the input face configured for coupling at a port station along a composite boom tube, the input face includes:
a carrier fluid fitting configured for coupling with a carrier fluid outlet port, the carrier fluid fitting in communication with the at least one passage configured for passage of carrier fluid, at the port station;
at least one injection product fitting configured for coupling with at least one injection product outlet port, the injection product outlet port in communication with the at least one passage configured for passage of injection product, at the port station; and
each of the carrier fluid fitting and the at least one injection product fitting are arranged on the input face complementary to the carrier outlet fluid port and the at least one injection product outlet port, respectively, to interface with the respective carrier fluid outlet port and the at least one injection product outlet port;
wherein the at least one interface clamp is configured to position and bias each of the carrier fluid fitting with the carrier outlet port and the at least one injection product fitting with the at least one injection product outlet port;

at least one throttling element arranged within the interface body and configured to deliver a flow of injection product to the at least one injection product fitting;
at least one flow measuring sensor disposed within the interface body and proximate to the at least one throttling element;
wherein the at least one flow measuring sensor measures at least one of flow rate or pressure differential of the injection product and is configured to provide an output to a control unit;

a mixing chamber in communication with each of the carrier fluid fitting and the at least one injection product fittings; and
an injection port interposed between the at least one throttling element and the mixing chamber, and in communication with the at least one throttling element and the mixing chamber, the injection port configured for localized coupling at a product dispenser and localized injection to the product dispenser.

2. The localized injection interface of claim 1 comprising an electronic control unit coupled with the at least one throttling element, the electronic control unit configured to control the at least one throttling element, the at least one flow measuring sensor and a corresponding injection product flow rate through the at least one throttling element.

3. The localized injection interface of claim 1 comprising the composite boom tube having the port station included with a plurality of port stations provided along the composite boom tube.

4. The localized injection interface of claim 1 comprising the product dispenser, the product dispenser includes a nozzle assembly coupled with the injection port.

5. The localized injection interface of claim 4 , wherein the nozzle assembly is integral to the localized injection interface.

6. The localized injection interface of claim 1 , wherein the mixing chamber includes one or more of vanes, flutes or passages configured to mix the injection product with the carrier fluid.

7. The localized injection interface of claim 1 wherein the at least one flow measuring sensor is a flow meter downstream from the throttling element; and
the flow meter is in communication with the at least one injection product fitting.

8. The localized injection interface of claim 1 comprising:
a first pressure transducer positioned upstream relative to the at least one injection product fitting; and
a second pressure transducer positioned downstream relative to the at least one injection product fitting, and between the mixing chamber and the at least one injection product fitting.

9. The localized injection interface of claim 1 , wherein the throttling element includes one or more of a control valve or pump.

10. The localized injection interface of claim 1 , wherein the at least one injection product outlet port is positioned along a perimeter segment of the composite boom tube corresponding the input face of the interface clamp.

11. The localized injection interface of claim 10 , wherein the at least one injection product outlet port is proximate to a horizontal diameter of the composite boom tube.

12. The localized injection interface of claim 1 wherein the carrier fluid outlet port is larger than the injection product outlet port; and
wherein the at least one interface clamp is configured to couple the carrier fluid outlet port with the carrier fluid fitting and guide the injection product outlet port to couple with the injection product fitting.

13. The localized injection interface of claim 1 , further including:
at least one check valve configured to prevent backflow of one or more of the injection products into the at least one injection product input.

14. The localized injection interface of claim 1 , wherein at least one of the partitions spans the composite boom tube.

15. A localized injection interface comprising:
an interface body including a mixing chamber;
wherein the interface body includes a coupling configured to close around a composite boom tube in a closed orientation, wherein the coupling positions and initiates communication between each of at least one carrier fluid fitting to a corresponding carrier fluid outlet port disposed along a perimeter of the interface body and at least one injection product fitting to at a corresponding injection product outlet port disposed along the perimeter of the interface body, and wherein the coupling biases and retains engagement between the at least one carrier fluid fitting with the corresponding carrier fluid outlet port and the at least one injection product fitting and the corresponding injection product outlet port;
