DETAILED DESCRIPTION OF THE INVENTION

(9) FIG. 1 shows apparatus generally indicated as 10 in the form of a coalescing removal separator having a separator tank 12 and a coalescing media 14 as shown in further detail in FIGS. 2-5.

(10) The separator tank 12 has a separator input I configured to receive fluid F flowing through a system (not shown) having entrained gasses G and solid particles P. The separator tank 12 has a tank wall W configured to form a volume/chamber C inside the separator tank 12 to process the fluid F. The separator tank 12 also has a separator output O configured to provide processed fluid FP that is free of at least some of the entrained gasses G and solid particles P.

(11) The coalescing media 14 is arranged in the volume/chamber C of the separator tank 12, and has at least one helically wound brush 16 with a stem S and intertwined bristles (IB) substantially filling the volume/chamber C of the separator tank 12 and being configured to enable the at least some of the entrained gasses G and solid particles P to come out of the fluid F, e.g., as coalesced gases and coalesced solid particles.

(12) The scope of the invention is not intended to be limited to the amount of the entrained gasses G and the solid particles P freed from the fluid F. For example, embodiments are envisioned, and the scope of the invention is intended to include, freeing at least some of the entrained gasses G and solid particles P from the fluid F in some applications, freeing most of the entrained gasses G and solid particles P from the fluid F in other applications, as well as freeing substantially all of the entrained gasses G and solid particles P from the fluid F in still other applications.

(13) By way of example, the coalescing media 14 may include a series of helically wound brushes 16, which is best shown in FIGS. 4-5. FIG. 2-5 show the coalescing media 14 having seven helically wound brushes 16, although the scope of the invention is not intended to be limited to any particular number of helically wound brushes 16. For instance, embodiments are envisioned, and the scope of the invention is intended to include, using more than seven helically wound brushes 16, or fewer than seven helically wound brushes 16. In FIG. 2-5, the seven helically wound brushes 16 are symmetrically arranged in three rows having a 2-3-2 format, although the scope of the invention is not intended to be limited to any particular arrangement or formatting of the helically wound brushes 16.

(14) The helically wound brushes 16 may include, or take the form of, at least one helically wound stainless steel brush, although the scope of the invention is not intended to be limited to any particular type or kind of the material, of which the helically wound brushes 16 are made. For example, embodiments are envisioned, and the scope of the invention is intended to include, using other types or kinds of materials either now known or later developed in the future.

(15) The stem S and the intertwined bristles IB are configured to contact the fluid F flowing through the coalescing media 14 to slow down the velocity of the fluid F enabling the entrained gasses G and solid particles P to come out of the fluid F, coalesce, and either rise to the top T of the separator tank 12 or fall to the bottom B of the separator tank 12. Helically wound brushes having a stem and intertwined bristles are known in the art, and the scope of the invention is not intended to be limited to any particular way in which the stem S and the intertwined bristles IB are configured. By way of example, and as one skilled in the art would appreciate, the term “intertwined” may be understood to mean “to unite by twining one with another” and the term “twine” may be understood to mean “to coil about a support.”

(16) The coalescing media 14 may include top and bottom plates P.sub.T, P.sub.B configured to couple together the series of helically wound brushes 16 for arranging, placing or mounting the coalescing media 14 inside the separator tank 12. Consistent with that shown in FIG. 1, the coalescing media 14 may arranged or placed in the separator tank 12, or may be mounted in the separator tank 12, although the scope of the invention is not intended to be limited to any particular type or kind of arrangement, placement, or mounting of the coalescing media 14 inside the separator tank 12. By way of example, and consistent with that shown in FIGS. 1 and 2, the stems S of the helically wound brushes 16 are connected to the top and bottom plates P.sub.T, P.sub.B. These connections may take the form of welding the stems S of the helically wound brushes 16 to the top and bottom plates P.sub.T, P.sub.B, or epoxying the stems S of the brushes 16 to the top and bottom plates P.sub.T, P.sub.B, although the scope of the invention is not intended to be limited to any particular type or kind of connection of the stems S of the helically wound brushes 16 to the top and bottom plates P.sub.T, P.sub.B. For example, embodiments are envisioned, and the scope of the invention is intended to include, using other types or kinds of connections either now known or later developed in the future.

(17) The top and bottom plates P.sub.T, P.sub.B may include top and bottom openings O.sub.T, O.sub.B configured or formed therein to enable the entrained gasses G and solid particles P that come out of the fluid F either to rise to the top T of the separator tank 12 or fall to the bottom B of the separator tank 12. FIGS. 2, 3A and 3B show the top and bottom plates P.sub.T, P.sub.B having twelve top and bottom openings O.sub.T, O.sub.B, although the scope of the invention is not intended to be limited to any particular number of top and bottom openings O.sub.T, O.sub.B. For example, embodiments are envisioned, and the scope of the invention is intended to include, using more than twelve top and bottom openings O.sub.T, O.sub.B, or fewer than twelve top and bottom openings O.sub.T, O.sub.B. In FIGS. 2, 3A and 3B, the twelve top and bottom openings O.sub.T, O.sub.B are symmetrically arranged in four rows having a 2-4-4-2 format, although the scope of the invention is not intended to be limited to any particular arrangement or formatting of the twelve top and bottom openings O.sub.T, O.sub.B.

(18) The apparatus 10 may include a hydronic HVAC system having the coalescing removal separator 10 arranged therein to remove the entrained gasses G and solid particles P from the fluid F flowing in the hydronic HVAC system.

(19) The separator tank 12 may include a top vent V configured to vent the entrained gasses G from the separator tank 12 and remove them from the system.

(20) The separator tank 12 may include a bottom blow-down BB configured to provide the solid particles P from the separator tank 12 and remove them from the system.
