This application claims benefit to provisional patent application serial no. 63/357,776, filed 1 July 2022, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a sediment and air separation device; and more particularly relates to a residential sediment and air separation device.

2. Brief Description of Related Art

Small coalescing removal separators are devices typically installed on residential hydronic HVAC systems to remove entrained gases (such as air) and solid particles (such as dirt and iron oxide) from the fluid flowing through the system. Gasses trapped in a hydronic system lead to potentially harmful corrosion. Solid particulates collect into sediment that can foul moving components in pumps or valves, damage sensors in the system, and clog heat exchangers and boilers, reducing system efficiency. Magnetic or ferrimagnetic particles can get trapped in pumps with electronically commutated motors, where magnets present will collect these particles that foul the moving components, reduce the pump’s efficiency and potentially damage the pump.

Residential coalescing removal separators work by passing the HVAC system fluid into a chamber, through a coalescent media, and back out to the system. The action of passing the fluid through the coalescent media enables the entrained gasses and particles to be removed from the system. The coalescent media disrupts the fluid flow and slows the fluid velocity, which allows gas bubbles to come out of solution and, through their natural buoyancy, float to the top of the main separator chamber to be vented out of the system. Likewise, the reduction in fluid velocity allows solids in the fluid, which are heavier than the system fluid to come out of solution and drop to the bottom of the chamber to be later removed through a blow-down action. A blow down action involves opening a valve or drain at the bottom of a removal separator chamber to atmosphere, utilizing the difference between atmospheric pressure and the system pressure inside the chamber to force out the solid contaminants that have come out of solution as they passed through the coalescent media. The coalescent media also provides a surface for dissolved gasses and solids to collect, or coalesce, around. As more dissolved gas or solids pass through the coalescent media, the molecules will continue to coalesce until they are either buoyant enough to float to the top or heavy enough to drop to the bottom.

A magnetic separation option may be needed for the separator to effectively remove sediment that contains mostly black iron oxide, also known as magnetite, or other ferromagnetic particles that are suspended in the water.

Shortcomings of the Above Mentioned Known Devices:

A number of problems with current residential hydronic separators exist. The coalescent media found in current residential separators can significantly increase the pressure drop of the unit, which can negatively impact the overall system efficiency. Another problem is that current residential separators may not effectively remove gasses or solids due to their designs. Current residential hydronic separators with a magnetic separation option offer their own unique sets of challenges. Most magnetic separation offerings do not do an effective enough job of removing magnetite or other ferromagnetic particles from hydronic system fluids. Residential separators with a magnetic separation option do not offer any visual indicator for the homeowner or regular maintenance person to know when the system needs to be serviced to remove any sediment or magnetite that had been collected in the separator.

SUMMARY OF THE INVENTION

The invention described here is a residential hydronic separator that improves the pressure drop characteristics across the separator while improving the ability of the device to more effectively remove gasses and solids, including ferromagnetic particles, from the system fluid.

This separator utilizes a coalescent medium consists of vertically assembled stainless steel perforated sheets, arranged such that they fill a large portion of the volume of the separator chamber. The sheets are assembled to each other to form a diamond shape. Alternately, the medium may be assembled from perforated corrugated stainless steel sheet, where the crests of the corrugation may be joined together to form the diamond shape described earlier. The coalescent medium may also be assembled from a single sheet where the ends are joined to form the diamond shape. The stainless steel perforated and/or corrugated sheets have an open area of 58% or greater, which facilitate the improved pressure drop characteristics. The open area of the diamond shape is conducive to the insertion of a magnetic insert inside a well assembly, which would be used to capture the magnetite or other ferromagnetic particles which may pass through the separator entrained in the system fluid.

The fluid flows into the separator through an inlet nozzle, into the separator chamber and through the coalescent sheet media, making contact with the face of the perforated stainless steel material to slow down the fluid velocity, enabling the entrained gasses and solids to come out of solution and either rise or sink, respectively, based on their buoyancy. The perforations of the coalescent sheet media provide multiple surfaces for dissolved gasses and solids to coalesce around.

The vertical diamond shape of the coalescent sheet media serves two purposes. First, the angled edges direct the fluid to pass through the coalescent sheet media where the greatest surface area contact could occur. Likewise, as the fluid has completed its pass through the coalescing sheet media, the reverse angled edges direct the fluid to the outlet, or discharge nozzle, to leave the separator, and allow the pressure drop to recover. These motions help reduce the overall pressure drop of the coalescing separator, compared to other different designs.

Second, the vertical alignment of the coalescent sheet media is rigid and resists the compressive forces that the coalescing sheet media would be subject to over the course of its operational lifetime. It is also resistant to any rotation.

The corrugated coalescing separator media is retained within the separator chamber by the chamber head at the top and a support ledge at the bottom of the chamber. This provides sufficient open area to permit gas bubbles to rise to the top of the separator and solids to fall to the bottom, while also providing ample space in the center for a magnetic separation insert. The magnetic separation insert consisting of a non-magnetic sleeve, preferably stainless steel, which surrounds an alternating stack of magnets and carbon steel spacers. The magnets are arranged with like poles towards each other. This has the effect of increasing the size of the magnetic field generated by the magnets and also increasing the magnetic flux, or number of magnetic fields generated by the magnet arrangement. As system fluid passes through the separation chamber, entrained ferromagnetic particles, such as magnetite, become attracted to the magnetic field generated by the magnets in the insert and collect there. Likewise, any other ferritic solids (like iron oxide or pure iron or steel particles) that have come out of solution via coalescing action would be attracted to the magnetic fields produced by the insert. The ferromagnetic and ferritic particles that collect on the magnetic separation insert further increase the size of the magnetic fields involved and increases the collection capability. The stack of magnets and spacers can be removed from the inside of the magnetic separation insert, which will allow the ferromagnetic particles attached to the insert and to each other to fall to the bottom of the residential separator. Opening a blowdown valve at the bottom of the separator to drain it will allow the system fluid to flush out these particles, along with any other sediment or debris that was collected inside the separator chamber.

A visual indicator to notify the system operator that maintenance needs to be performed is accomplished through a sensor outside of the separator chamber. The sensor detects the magnetic flux, or increase in magnetic field activity, that increases as more ferromagnetic particles collect on the magnetic insert sleeve. The sensor, either a Hall Effect sensor, reed switch, or other type of magnetic flux sensing, detects the increased size of the magnetic field as the amount of ferromagnetic and ferritic particles that collect on the magnetic separation insert increases. When the sensor detects the desired threshold amount of magnetic field or flux, a light on the separator will either light up, begin to blink or change colors, indicating that maintenance is necessary on the separator or system. Upon magnet removal and system blowdown or flushing, the subsequent reduction in magnetic field will cause the light to turn off.

Figures 9A and 9B show the vertically aligned corrugated perforated sheets 22 in the form of vertically aligned corrugated perforated sheets that may have peaks 22d, crests 22e and surfaces 22f inbetween, and may be assembled to each other where a peak 22d of one corrugation is assembled to a crest 22e of another corrugation. Alternatively, the series of vertically aligned corrugated perforated sheets 22 having the peaks 22d and crests 22e may be assembled to each other peak-to-peak and crest-to- crest. In other words, the scope of the invention is not intended to be limited to any particular alignment of peaks and crests of the vertically aligned corrugated perforated sheets 22. In Figures 9A and 9B, each vertically aligned corrugated perforated sheet 22 has three (3) peaks 22d, four (4) crests 22e and six (6) surfaces 22f inbetween. (The terms "peaks" and "crests" may be used interchangeably within the spirit of the invention.)

The Vertically Aligned Perforated Sheets

The series of vertically aligned corrugated perforated sheets 22 may have multiple openings or perforations 22b that provide multiple surfaces for dissolved gasses and solids or particles to coalesce around. By way of example, and consistent with that shown in Figures 9A, 9B, the multiple openings or perforations 22b may be circular openings or perforations and the multiple surfaces may be circular or cylindrical surfaces, e.g., so as to be uniformly configured on the vertically aligned corrugated perforated sheets 32. However, the scope of the invention is intended to include, and embodiments are envisioned that include, the multiple openings or perforations 22b and the multiple surfaces having different types or kinds of shapes and surfaces within the spirit of the underlying invention, e.g., including a triangular shape and surface, a rectangular shape and surface, a square shape and surface, a hexagon shape and surface, etc. In other words, the scope of the invention is not intended to be limited to the shape of the opening or perforation 22b and its associated surface. For example, in one type of application the multiple openings or perforations 34 may have one shape and surface, while in another another application, the multiple openings or perforations 22b may have another shape and surface, as one skilled in the art would appreciate.

Moreover, and by way of further example, and consistent with that shown in Figures 9A, 9B, the multiple openings or perforations 22b may be configured or dimensioned having the same size, e.g., so as to be uniformly distributed on the vertically aligned corrugated perforated sheets 22. However, the scope of the invention is intended to include, and embodiments are envisioned that include, the multiple openings or perforations 22b having different sizes within the spirit of the underlying invention. Moreover, the scope of the invention is not intended to be limited to the size of the multiple openings or perforations 22b, e.g., which may be configured or dimensioned with a particular size based upon a particular application as one skilled in the would appreciate. For example, in one type of application the multiple openings or perforations 22b may have one size or dimension, while in another another application, the multiple openings or perforations 22b may have another and different size or dimension.

Moreover still, and by way of still further example, and consistent with that shown in Figures 9A, 9B, the multiple openings or perforations 22b may be configured, dimensioned or spaced in relation to one another having the same distance inbetween, e.g., so as to be uniformly distributed on the vertically aligned corrugated perforated sheets 22. However, the scope of the invention is intended to include, and embodiments are envisioned that include, the multiple openings or perforations 22b having different distances inbetween within the spirit of the underlying invention. Moreover, the scope of the invention is not intended to be limited to any particular distances inbetween the multiple openings or perforations 22b, e.g., which may be configured or dimensioned with a particular distance inbetween based upon a particular application as one skilled in the would appreciate. For example, in one type of application the multiple openings or perforations 22b may have one distance inbetween, while in another application, the multiple openings or perforations 22b may have another and and different distance inbetween.

The series of vertically aligned corrugated perforated sheets 22 may have angled corrugations that direct the fluid to pass through the coalescing media 20 where greatest surface contact occurs. By way of example, and consistent with that shown in Figures 9A and 9B, the vertically aligned corrugated perforated sheets 22 have angled corrugations with a 90° angle (i.e. right angle). As the fluid has completed its pass through the coalescing media 20, the angled corrugations may direct the fluid to the separator output 0 to leave the coalescing removal separator 10 and allow a pressure drop to recover. However, the scope of the invention is intended to include, and embodiments are envisioned that include, the angled corrugations having a different angle within the spirit of the underlying invention. For example, the scope of the invention is intended to include, and embodiments are envisioned that include, the angled corrugations being more or less than 90°, e.g., so as to be configured or dimensioned with a particular angled corrugation based upon a particular application as one skilled in the would appreciate. For example, in one type of application the angled corrugation may have one angle, while in another another application, the angled corrugation may have another and different angle.
