Flow governor and limiter disc assembly in an extraction column
A flow limiter system is provided for extracting compounds from raw materials with an extraction column. The flow limiter system may include a flow governor assembly which contains and buffers a flow of pressurized solvent entering the base of the extraction column to prevent the flow of pressurized solvent from drilling into the raw materials packed within the extraction column. The flow governor assembly may further include a first disc with a first set of perforations to direct the surge of solvent through the first disc to transform the turbulent surge of solvent into a column of non-turbulent solvent with a flat surface layer that rises up the extraction column evenly and collectively. Additionally, the flow limiter system may also include a limiter disc including a second set of perforations to allow the extracted effluent to flow through the set of perforations and exit the extraction column.
1. A flow governor assembly comprising:
a first disc that contains and buffers a flow of pressurized solvent entering a base of an extraction column to prevent the flow of pressurized solvent that is turbulent from drilling into the raw materials packed within the extraction column;
wherein the first disc comprises a first set of perforations allowing portions of the solvent to pass through the first disc causing the flow of solvent to be reconstructed into a non-turbulent surge-free well of solvent with a flat surface layer that evenly and collectively rises up the extraction column;
a second disc with a set of perforations configured to receive the flow of pressurized solvent passing through the first disc to further ensure the breaking up of the turbulent flow of pressurized solvent; and
a third disc comprising a second set of perforations configured to receive the flow of pressurized solvent from the second disc to ensure that the flow of pressurized solvent passing through the second set of perforations results in the formation of a non-turbulent surge-free well of solvent with a flat, evenly dispersed surface layer.
2. The flow governor assembly of claim 1 , wherein the first set of perforations is arranged in a symmetrical pattern.
3. The flow governor assembly of claim 1 , wherein the first set of perforations is configured to have more perforations concentrated towards a middle of the first disc to ensure centering of hydraulic force and pressure within the extraction column as more flow of pressurized solvent passes through the middle of the first disc.
4. The flow governor assembly of claim 1 , wherein the set of perforations is arranged in a symmetrical pattern with more perforations concentrated towards a middle of the second disc to ensure centering of hydraulic force and pressure within the extraction column as more flow of pressurized solvent passes through the middle of the second disc.
5. The flow governor assembly of claim 1 , wherein the second set of perforations is arranged in a symmetrical pattern with more perforations concentrated towards a middle of the third disc to ensure centering of hydraulic force and pressure within the extraction column as more flow of pressurized solvent passes through the middle of the third disc.
6. The flow governor assembly of claim 1 , wherein the flow governor assembly is placed next to a connector inlet at the base of the extraction column, such that the incoming flow of solvent meets the flow governor assembly as the flow of solvent first enters the base of the extraction column.
7. A flow governor assembly comprising:
a first disc that contains and buffers a flow of pressurized solvent entering a base of an extraction column to prevent the flow of pressurized solvent that is turbulent from drilling into the raw materials packed within the extraction column;
wherein the first disc comprises a first set of perforations allowing portions of the solvent to pass through the first disc causing the flow of solvent to be reconstructed into a non-turbulent surge-free well of solvent with a flat surface layer that evenly and collectively rises up the extraction column;
wherein the first disc further comprises an misalignment marker to ensure misalignment of the perforations with a second disc and a third disc, such that the second disc and the third disc each have corresponding misalignment markers to be misaligned with the first disc to ensure the formation of a non-turbulent surge of solvent with a flat, evenly dispersed surface layer.
8. A system comprising:
a flow governor assembly that contains and buffers a flow of pressurized solvent entering a base of an extraction column to prevent the flow of pressurized solvent that is turbulent from drilling into the raw materials packed within the extraction column;
wherein the flow governor assembly comprises at least a first disc with a first set of perforations to direct the surge of solvent through the first disc and transform the turbulent surge of solvent into a column of non-turbulent solvent with a flat surface layer that rises up the extraction column evenly and collectively;
wherein the flow governor assembly further comprises a second disc and a third disc aligned with the first disc, wherein the second and third discs comprise perforations, such that the second disc and third disc further break up the incoming flow of pressurized solvent to form the flow of non-turbulent solvent with a flat, even surface layer; and
a limiter disc comprising a set of perforations to allow an extracted effluent from raw materials to flow through the second set of perforations and exit the extraction column.
9. The system of claim 8 , wherein a number and size of the perforations are manipulated such that a rate of the pressurized solvent entering the base of the extraction column and into the flow governor assembly is twice the rate of extracted effluent passing through the limiter disc and exiting the extraction column resulting in a formation of a pressure differential.
10. The system of claim 9 , wherein the pressure differential within the extraction column causes the flow of pressurized solvent not directed through the second set of perforations of the limiter disc to be redirected back down towards a base of the extraction column causing the raw materials with areas of low energy to be recharged to ensure all the raw materials are extracted.
11. The system of claim 9 , wherein the rate of pressurized solvent flowing through the flow governor assembly and the rate of the extracted effluent passing through the limiter disc is at a differential flow ratio of at least one of 2:1, 3:1, 4:1, 5:1, or 6:1 flow ratio.
12. The system of claim 8 , wherein the first disc, second disc, and third disc are each equally spaced between 1-2 mm from one another to help ensure the flowing of solvent through each disc.
13. The system of claim 8 , wherein forming the column of non-turbulent solvent with the flat surface layer that rises up through the extraction column evenly and collectively results in an efficient upward hydraulic compression of the raw materials, and further aids in closing off interstitial spaces and low resistance migration travel ways within the raw materials.
