Carbon dioxide driven water carbonating system
A motorless water carbonation system includes a CO2 driven double piston booster pump mounted over a pressurized chamber comprising CO2 and carbonated water. A supply of CO2 enters a lower part of chamber, and is partially absorbed in water and collects at the top of the chamber where it is used to drive the pump. The pump delivers high-pressure water into the top of the chamber, passing through a Venturi mixing nozzle which draws the CO2. The CO2 and water mixture is then injected on the surface of the water, creating turbulence to promote more mixing and carbonation.
1 . A two-stage carbon dioxide (CO2) driven water carbonating method comprising the steps of:
introducing CO2 into water located in a reservoir body, a first portion of the CO2 being absorbed into the water to carbonate the water in a first carbonating stage, and a second portion of the CO2 collecting in the reservoir body above the water;
using the second portion of the CO2 to drive a boosting pump to boost pressure of the water during operation of the boosting pump; and
introducing the water from the boosting pump into the reservoir body to mix with CO2 in the reservoir body to facilitate a second carbonating stage.
2 . The method recited in claim 1 , wherein the step of introducing the water includes injecting the water into the reservoir body through a Venturi mixing valve.
3 . The method recited in claim 1 , wherein the step of introducing CO2 into the water includes introducing the CO2 via a mixing valve.
4 . The method recited in claim 1 , further comprising the step of facilitating dispensing of carbonated water from the reservoir body.
5 . The method recited in claim 1 , wherein all steps are performed independent of electricity being supplied to the boosting pump.
6 . The method recited in claim 1 , further comprising the step of receiving water at the boosting pump.
7 . The method recited in claim 1 , wherein the step of receiving water at the boosting pump includes receiving pressurized water at the boosting pump.
8 . A two-stage carbon dioxide (CO2) driven water carbonating method comprising the steps of:
facilitating a first carbonating stage by allowing CO2 to absorb into water located in a reservoir body;
receiving pressurized CO2 from the reservoir body at a boosting pump configured to boost pressure of water flowing through the pump using the pressurized CO2; and
facilitating a second carbonating stage by directing water from the boosting pump into the reservoir body to enable mixing with CO2 in the reservoir body.
9 . The method recited in claim 8 , wherein the step of facilitating a first carbonating stage includes introducing CO2 into the water.
10 . The method recited in claim 9 , wherein the step of introducing CO2 into the water includes introducing the CO2 via a mixing valve.
11 . The method recited in claim 10 , wherein the mixing valve is a stone bubbler.
12 . The method recited in claim 8 , wherein the step of facilitating a second carbonating stage includes injecting the water into the reservoir body through a Venturi mixing valve.
13 . The method recited in claim 8 , wherein the water received at the boosting pump is pressurized.
14 . The method recited in claim 8 , further comprising the step of facilitating dispensing of carbonated water from the reservoir body.
15 . A carbonating method adapted to enable carbonation of water through the use of the pump configured to operate solely based on fluid pressure and without requiring electricity, the method comprising the steps of:
directing pressurized carbon dioxide (CO2) into water located in a reservoir to induce mixing of the pressurized CO2 and the water as part of a first carbonating stage;
allowing a portion of the pressurized CO2 to gather above the water in the reservoir;
using the gathered pressurized CO2 to drive a boosting pump;
receiving water at the boosting pump;
increasing the pressure of the received water by driving the boosting pump; and
discharging the water from the boosting pump into the reservoir to mix with CO2 as part of a second carbonating stage.
16 . The method recited in claim 15 , wherein the step of directing pressurized CO2 into the water includes introducing the CO2 via a mixing valve.
17 . The method recited in claim 16 , wherein the step of introducing CO2 via a mixing valve includes introducing CO2 through a Venturi mixing valve.
18 . The method recited in claim 16 , wherein the step of introducing CO2 via a mixing valve includes introducing CO2 through a stone bubbler.
19 . The method recited in claim 15 , wherein the water received at the boosting pump is pressurized.
20 . The method recited in claim 15 , further comprising the step of facilitating dispensing of carbonated water from the reservoir.
