Abstract

A fluid suspension tube comprises at least one intake tube section (101) comprising a throttle (102) for accelerating a fluid flow received at the intake tube section, a fluid suspension chamber (103) connected to the intake tube section, and an outtake tube section (104) connected to the fluid suspension chamber and for conducting the fluid flow out from the fluid suspension chamber. A transitional region (105) from the intake tube section to the fluid suspension chamber forms an enlargement of a cross-sectional flow area for slowing down the accelerated fluid flow. Kinetic energy of the accelerated fluid flow is advantageous for achieving desired reactions between ingredients of the fluid flow as well as for reduction of retention time. In the fluid suspension chamber, the kinetic energy is at least partially converted to pressure without additional energy consumption.

Description

A fluid suspension tube Field of the disclosure The disclosure relates to a fluid suspension tube for fluid treatment applications such as for example but not necessarily: launch of immediate chemical reactions, reduction of retention time, chemistry control by hermetic treatment, energy conversion from kinetic to pressure based, mixing, dissolving, chemical and ionic bond breaking by cavitation, pretreatment for mechanical and/or chemical separation, and pretreatment for flotation and/or filtering.
Background Treatment forced by kinetic energy is a feasible and widely used method to achieve desired and demanded chemical reactions in fluids such as for example water, waste water, air, or their blend.
Particularly, the kinetic energy can be applied in mixing, dissolving, cavitation, pretreatment for mechanical and/or chemical separation, and pretreatment for flotation and/or filtering.
Kinetic energy for treatment of the kind mentioned above can be created by converting pressure of fluid to the kinetic energy.
In conjunction with many kinetic fluid treatments of the kind mentioned above, a retention time that is needed for desirable chemical reactions is relatively long, from minutes to hours.
After the treatment, the kinetic energy of the fluid is often demanded to be converted at least partially back to > pressure.
The kinetic energy could be easily and beneficially converted to N mechanical and/or electrical power, but typically this is not a desired operation in & case of fluid treatments.
The kinetic energy can be converted to pressure by a pump, N but this causes additional capital, maintenance, and energy costs.
Furthermore, this E 25 might be even impossible when the treated fluid contains a significant portion of gas.
N When designing a device or a system for kinetic fluid treatment of the kind = mentioned above, typical design targets are, among others, energy efficiency in N accelerating the fluid to increase the kinetic energy of the fluid, advantageous conditions for the desired reactions in the fluid, and energy efficiency in converting the kinetic energy of the accelerated fluid to pressure after the treatment.
Furthermore, a retention time that is needed for the desirable reactions is advantageously short to achieve an effective treatment process. In view of the above-mentioned design targets, there is still a need for new designs of devices and systems for kinetic fluid treatments of the kind mentioned above. Summary The following presents a simplified summary in order to provide a basic understanding of some embodiments of the invention. The summary is not an extensive overview of the invention. It is neither intended to identify key or critical elements of the invention nor to delineate the scope of the invention. The following summary merely presents some concepts of the invention in a simplified form as a prelude to a more detailed description of exemplifying embodiments of the invention. In this document, the word “geometric” when used as a prefix means a geometric concept that is not necessarily a part of any physical object. The geometric concept can be for example a geometric point, a straight or curved geometric line, a geometric plane, a non-planar geometric surface, a geometric space, or any other geometric entity that is zero, one, two, or three dimensional. In accordance with the invention, there is provided a new fluid suspension tube for fluid treatment applications such as for example but not necessarily: launch of immediate chemical reactions, reduction of retention time, chemistry control by hermetic treatment, energy conversion from kinetic to pressure based, mixing, > dissolving, chemical and ionic bond breaking cavitation, pretreatment for N mechanical and/or chemical separation, and pretreatment for flotation and/or & filtering.
N E A fluid suspension tube according to the invention comprises: = 25 - at least one intake tube section comprising a throttle or a nozzle for 3 accelerating a fluid flow received at the intake tube section,
O
N - a fluid suspension chamber connected to the intake tube section, a transitional region from the intake tube section to the fluid suspension chamber forming an enlargement of a cross-sectional flow area for slowing down the accelerated fluid flow, and - an outtake tube section connected to the fluid suspension chamber and for conducting the fluid flow out from the fluid suspension chamber.
In a process taking place in the above-described fluid suspension tube, accelerated fluid portions hit earlier arrived fluid portions slowed down in the fluid suspension chamber. Therefore, conditions suitable for kinetic fluid treatment are created and the kinetic energy of the accelerated fluid can be used for desired reactions and for reduction of a retention time. In the slowdown process, the kinetic energy of the accelerated fluid is at least partially converted back to pressure of the fluid in an energy efficient way. Therefore, energy consumption and losses can be small in the above-described fluid suspension tube. Furthermore, kinetic energy of liquid and gas mixtures can be converted to pressure without problems that are typically present when using a pump for increasing pressure.

In the above-mentioned transitional region 105, accelerated fluid portions hit earlier arrived fluid portions slowed down in the fluid 5 suspension chamber 103. Therefore, conditions suitable for kinetic fluid treatment are created and the kinetic energy of the accelerated fluid can be used for desired reactions and for reduction of a retention time. In the slowdown process, the kinetic energy of the accelerated fluid is at least partially converted back to pressure of the fluid in an energy efficient way. Therefore, energy consumption and losses can be — small. The fluid suspension tube can be made of e.g. metal or plastic. The metal can be e.g. stainless steel.
In the exemplifying fluid suspension tube illustrated in figure 1, the intake tube section 101 is configured to conduct the fluid flow into the fluid suspension chamber in a same direction in which the outtake tube section 104 is configured to conduct — the fluid out from the fluid suspension chamber. In figure 1, the direction in which the intake tube section 101 and the outtake tube section 104 are configured to conduct the fluid is the positive z-direction of the coordinate system 199. In this exemplifying fluid suspension tube, the cross-sectional flow area of the outtake tube section 104 is same as the cross-sectional flow area of the suspension chamber
103. lt is also possible that the cross-sectional flow area of the outtake tube section is smaller than the cross-sectional flow area of the suspension chamber.

The intake tube section 201 = and the fluid suspension chamber 203 are shaped so that a transitional region from 3 the intake tube section 201 to the fluid suspension chamber 203 forms an N 30 enlargement of a cross-sectional flow area for slowing down the accelerated fluid flow. The fluid suspension tube comprises an outtake tube section 204 that is connected to the fluid suspension chamber 203 and conducts the fluid flow out from the fluid suspension chamber 203. In the exemplifying fluid suspension tube illustrated in figure 2, the intake tube section 201 is configured direct the fluid flow towards a wall 206 of the fluid suspension chamber to slow down the fluid flow.

It is however also possible to connect the intake g 25 — tube sections in different ways to the fluid suspension chamber 403. For example, N in a fluid suspension tube according to another exemplifying and non-limiting E embodiment, first intake tube sections are parallel with the z-axis of a coordinate — system 499 whereas second intake tube sections are parallel with the x-axis of the 3 coordinate system 499.
