Apparatus and method for liquids and gases
Aspects of the present disclosure provide various apparatus and methods. In some embodiments, an apparatus is provided for mixing a gas with a liquid. The apparatus may include a pipe having two ends. The pipe may provide a main fluid path and may have an interior surface having a first groove. The apparatus may also include a helical vane disposed inside the pipe. The vane may have a first projecting tongue that engages the first groove. The apparatus may also include a gas injection port on the pipe adapted to inject gas into the fluid path upstream of the helical vane. In some embodiments, the helical vane may be a 3D printed component.
1. An apparatus for mixing a gas with a liquid, the apparatus comprising:
a tube having a longitudinal axis and two ends, with a first end being a liquid input end and a second end being a liquid outlet end, the tube providing a first portion of a main fluid path that extends through the apparatus;
a helical vane disposed inside the tube, dividing the first portion of the main fluid path into two fluid path regions;
a tubular structure extending from the first end of the tube and located upstream of the helical vane and aligned with the longitudinal axis of the tube, the tubular structure providing a second portion of the main fluid path and having a sidewall configured to allow gas to flow there through at a plurality of locations around a circumference of the tubular structure;
a joint pipe having an inner wall defining an inner diameter sized to receive the tubular structure and the first end of the tube, and to provide an annular space between the inner wall and the sidewall of the tubular structure;
a gas injection port associated with the joint pipe and located upstream of the helical vane, the gas injection port adapted to inject gas into the annular space, through the sidewall of the tubular structure and into the second portion of the main fluid path provided by the tubular structure; and
a ring structure located upstream of the helical vane and downstream of the gas injection port and the tubular structure, the ring structure extending around an outer wall of the tube and positioned between the inner wall of the joint pipe and the outer wall of the tube to define a downstream end of the annular space.
2. The apparatus of claim 1 , wherein the tube and the helical vane are a single three-dimensional (3D) printed component.
3. The apparatus of claim 1 , further comprising a gas supply, wherein the gas comprises oxygen.
4. The apparatus of claim 1 , further comprising a gas supply, wherein the gas comprises carbon dioxide.
5. The apparatus of claim 1 , further comprising a liquid supply, wherein the liquid comprises water.
6. The apparatus of claim 1 , wherein the helical vane is a 3D printed component.
7. The apparatus of claim 1 , further comprising a second helical vane disposed downstream from the helical vane.
8. The apparatus of claim 1 , further comprising a pipe, wherein the tube with the helical vane is disposed within the pipe.
9. The apparatus of claim 1 , wherein the tubular structure is integral with the end of the tube, and the plurality of locations around a circumference of the tubular structure are provided by holes that extend through the sidewall of the tubular structure.
10. The apparatus of claim 1 , wherein the tubular structure is a porous membrane having an inner wall in snug contact with the first end of the tube, and the plurality of locations around a circumference of the tubular structure are provided by pores that extend through the sidewall.
11. The apparatus of claim 1 , wherein the gas injection port is at least partially aligned with the sidewall of the tubular structure.
12. The apparatus of claim 1 , wherein the tube and the helical vane are unitary with each other.
13. The apparatus of claim 1 , wherein the annular space between the inner wall of the joint pipe and the sidewall of the tubular structure extends along the entirety of the tubular structure.
