The further deliquescing of the gas is then transferred to a third collection tank, and further deliquescing of the gas is transferred through the second inertial separator and exits from the pressure vessel through an outlet.

[0074] For example, in one aspect, the method includes passing gas into the inlet of a pressure vessel in which the filter-coalescing arrangement is arranged; passing the gas through a hollow cylindrical pre-filter in an outward-to-inward flow manner; separating liquid from the gas, wherein the separated liquid is passed from the outside of the pre-filter to a first collection tank, and the dehydrated gas is passed along the hollow portion of the pre-filter and through a first inertial separator comprising a vortex generator and an axial flow separator (the axial flow separator comprising a hollow axial flow body); separating further liquid from the gas, the separated liquid being passed from the outside of the axial flow body to a second collection tank, wherein further dehydrated gas is passed along the hollow axial flow body to a hollow coalescer; separating further liquid from the gas, wherein the liquid is discharged from the outside of the coalescer and discharged along the curved plate into the second collection tank, and the gas is passed along the hollow coalescer and exited from the pressure vessel through the outlet of the pressure vessel. Aspects of the method may include passing the separated liquid along the curved plate and through a conduit, the conduit being vertically connected to guide the coalesced liquid from the coalescer to the second collection tank.

[0075] According to another aspect of the invention, a method for removing solid contaminants and separating liquid contaminants from an airflow is provided, the method comprising passing the airflow through at least one coalescing arrangement, the at least one coalescing arrangement comprising: (a) an inertial separator including (i) a vortex generator including helical blades; and (ii) an axial flow separator including a hollow cylindrical axial flow body having a first open separator end and a second open separator end, the axial flow separator being in fluid communication with the vortex generator; (b) a coalescing device including a porous coalescing medium, a first open coalescing end and a second open coalescing end, and a closed coalescing end cap in the second open coalescing end, the coalescing device being arranged adjacent to the second open separator end and in fluid communication with the axial flow separator, wherein a curved plate is arranged below the coalescing device; wherein (a) and (b) are arranged sequentially and remove solid and liquid contaminants from the airflow.

[0077] Advantageously, aspects of the present invention allow for the use of shorter filter and / or coalescer elements (weighing less than conventional filter / coalescer elements) and smaller pressure vessels without increasing the filtration area, while maintaining the required separation efficiency and flow rates based on different process conditions. Smaller vessels occupy less space and can reduce costs (e.g., cheaper filter / coalescer elements or coalescer elements; reduced energy consumption for operating and / or producing filter-coalescer units and / or producing filter-coalescer systems or coalescer systems).

[0078] In some respects, the second inertial separator and / or pre-filter can be omitted, thereby further reducing container size and further reducing costs.

[0079] Another advantage is that the filter-coalescing system and the coalescing system can be serviced, for example, by removing the pre-filter and / or filter-coalescing arrangement from the pressure vessel and inserting a replacement pre-filter and / or filter-coalescing arrangement into the pressure vessel, or by removing the coalescing arrangement from the pressure vessel and inserting a replacement coalescing arrangement into the pressure vessel.

Figure 7A and 7B Top view and side view are shown. Figure 7A A top view is shown; Figure 7B (A side view is shown). Figure 7C A front view including the first endplate 501 is shown; Figure 7D A rear view including a second end plate 502 is shown, wherein the first end plate 501 has a first surface 501A and a second surface 501B of the first end plate, the second surface 501B being adjacent to a first end of at least one pre-filter; and the second end plate 502 has a first surface 502A and a second surface 502B of the second end plate, the first surface 502A being adjacent to a second end of the coalescer.

Figure 4C and 7G ).like Figure 7G As shown, the snap-fit ​​feature 555 includes spaced parallel walls 556 extending from the central support 557 on the upper side of the second end plate, wherein the spacing between the walls is slightly greater than the width of the handle 365, and the plate 502 has a partially crescent-shaped opening 558 on either side of the central support 557.

[0099] In some respects, when assembling and / or repairing the 600 / 600A in System 2000 (see also...) Figures 8A-8B And 11A-11B, as described below; see also System 2000', as described below regarding Figures 9A-9D As described above, and System 2000A, as follows regarding Figure 12A-12F As described above), when inserting arrangement 500 / coalescing arrangement 500A (see...) Figure 12A-12F When the pre-filter 100 is disengaged (e.g., involving disconnecting and disengaging the pre-filter and eddy current generator from the axial flow separator and coalescer), the handle 365 may engage in the snap-fit ​​feature 555 / 555' to ensure proper assembly, and / or once engaged, the arrangement may be rotated to disengage the connector (if present), thereby allowing the removal of the pre-filter and keeping the coalescer in place to insert a replacement pre-filter and re-engage the connector.

[0100] As will be discussed below, in those aspects including the coalescer arrangement 500A, the handle 365 may engage in the snap-fit ​​feature 555' to ensure proper assembly, and / or once engaged, the arrangement may be rotated to disengage the coalescer arrangement, thereby allowing removal of the coalescer arrangement and subsequent insertion of a replacement coalescer arrangement.

[0101] When the arrangement 500 / 500A is inserted into the pressure vessels 1000, 1000', 1000" (typically from the inlet side), it may be desirable that the holes in the second tube sheet 1250 are smaller than the holes in the first tube sheet 1150, so that the gasket associated with the coalescer 300 can slide through more easily.

[0102] As described above, the device 600 in system 2000 (and the devices in system 2000', and the device 600A in system 2000A as described below) can be assembled and / or repaired. For example, the filter-coalescing arrangement 500 can be inserted into the pressure vessel for assembly, or the filter-coalescing arrangement 500 or the pre-filter 100 can be removed from the pressure vessel and a replacement filter-coalescing arrangement 500 or the pre-filter 100 can be inserted, wherein the pre-filter can be removed and replaced after the connector is disengaged.

During the removal and replacement of the pre-filter 100, the pre-filter is slidable along the parallel pre-filter rail 585. A generally similar procedure can also be followed to remove and replace the coalescer arrangement 500A, wherein the coalescer arrangement 500A is slidable along the coalescer rail 595' (the rail is arranged along the upper surface of the coalescer arrangement (above the upper surface)). Typically, the coalescer arrangement can be removed and replaced without the use of a coupling.

[0103] exist Figures 9A-9D In the illustrated aspect, multiple filter-coalescing arrangements are arranged in another aspect of the filter-coalescing system. The illustrated filter-coalescing arrangement 500 includes: (a) at least one pre-filter 100 comprising a hollow porous medium 150 (optionally a pleated hollow porous medium) having a first open pre-filter end 151 and a second open pre-filter end 152 (the pre-filter optionally includes a perforated metal core, typically having at least 30% of the open area (metal core not shown), and optionally also includes a baffle 111); the pre-filter further includes a closed pre-filter end cap 160 disposed in the first open pre-filter end (including an optional handle 161; see also...). Figure 2 (b) A first inertial separator 200, the first inertial separator comprising (i) an eddy current generator 210, the eddy current generator comprising helical blades 211 (see Figure 2 and 3C -3D, the vortex generator is in fluid communication with at least one pre-filter 100; and (ii) an axial flow separator 250, the axial flow separator comprising a hollow cylindrical axial flow body 255 having a first open separator end 261 and a second open separator end 262 (see...). Figure 2 See also Figure 4G-4J (c) The content regarding axial flow separators 250' and 250" in the document, the axial flow separator being in fluid communication with vortex generator 210; (d) a coalescer 300, the coalescer including a hollow porous coalescer medium 301, a first open coalescer end 311 and a second open coalescer end 312, and a closed coalescer end cap 360 in the second open coalescer end 312, the end cap including a handle 365; see also Figure 4C The coalescer is arranged adjacent to the second open separator end 262 and is in fluid communication with the axial flow separator 250.

[0104] However, regarding the coalescer 300 in arrangement 500, the aspect shown in system 2000' also includes a curved plate 350' that contacts the second end plate 502 and the second tube sheet 1250. The curved plate has a first end 351' contacting the second tube sheet and a second end 352' contacting the second end plate. The curved plate is arranged below the hollow coalescer 300 and surrounds the lower portion of the coalescer, and partially surrounds the side of the coalescer, to separate additional liquid (e.g., droplets) from the gas. This additional liquid is discharged from outside the coalescer and flows along the curved plate, being transferred through a discharge point 353' (located between the first end 351' and the second end 352') to a second collection tank (thus minimizing or preventing the coalesced liquid from re-entering the clean gas flow and isolating the gas flow from each individual coalescer while guiding the gas flow upwards). The gas is then discharged from the pressure vessel along the hollow coalescer and through the outlet of the pressure vessel. Preferably, the curved plate covers 50-75% of the side of the coalescer (see...). Figure 9E In some respects, the curved plate has a radius that varies along the length of the coalescer, and the frame has a larger radius R1 at the discharge point 353' and smaller radii R2 and R3 at ends 351' and 352', respectively (see...). Figure 9B It includes a conduit 354', which is vertically connected to guide the coalesced liquid from the coalescer to the second collection tank.

[0105] like Figure 9E As shown, near the discharge point 353' of the curved plate 350', wherein the plate surrounds the lower portion of the coalescer and the side portion of the coalescer, the gap between the plate and the lower portion of the coalescer is smaller than the gap between the plate and the side portion of the coalescer.

[0106] and Figure 7D and 7F Compared to the snap-fit ​​element 555 shown, it is used to receive such as Figure 11A The snap-fit ​​feature 555' of the handle shown (see also) Figure 15D , 15F (16A and 16B) lack a central support 557 and an opening 558, thereby providing surface area on the second plate 502 or end plate 512 for the second end 352' of the bent plate 350' to abut.

[0107] The difference between System 2000' and System 2000 is that System 2000' does not require a second inertial separator, a third liquid port, or a third collection tank.

[0108] The illustrated aspect of the filter-coalescing arrangement 500 is arranged in the filter-coalescing system 2000', shown as including a pressure vessel 1000', the pressure vessel including a pressure vessel inlet 1001, a pressure vessel outlet 1002, a first chamber 1100, a first liquid port 1101 for transferring separated liquid to a first collection tank 1102, a first tube sheet 1150, a second chamber 1200, a second liquid port 1201 for transferring separated liquid to a second collection tank 1202, a second tube sheet 1250, and a third chamber 1300; the first chamber 1100... System 2000 includes a pressure vessel inlet 1001, at least one pre-filter 100, and a first liquid port; a second chamber 1200 includes a first inertial separator 200 and a second liquid port, wherein a first tube sheet 1150 separates the first chamber 1100 from the second chamber 1200; a third chamber 1300 includes a coalescer 300, a bend plate 350', and a conduit 354' (system 2000' does not have a second inertial separator, a third liquid port, or a third collection tank) and a pressure vessel outlet 1002, wherein a second tube sheet 1250 separates the second chamber 1200 from the third chamber 1300.

[0109] As described with respect to system 2000, in the illustrated aspect of system 2000', the tube sheet has concentric orifices, thereby dividing the interior of the pressure vessel into three chambers. Gaskets located at the second-opening pre-filter end 152 and the first-opening coalescer end 311 provide a seal between the pre-filter and coalescer and the tube sheet. In some aspects, the diameter of the orifices in the second tube sheet is smaller than the diameter of the orifices in the first tube sheet.

[0110] Pressure vessel 1000' has a first end 1000A before at least one pre-filter and pressure vessel inlet, and a second end 1000B after pressure vessel outlet, wherein the first end has a hinged openable hatch 1400, and the second end is closed.

The trough; or, the hollow cylindrical axial flow body comprises an inner hollow cylindrical porous metal element and an outer hollow cylindrical metal mesh; wherein the axial flow separator is in fluid communication with the vortex generator; and (b) a coalescer, the coalescer comprising a porous coalescer medium, a first open coalescer end and a second open coalescer end, and a closed coalescer end cap in the second open coalescer end, the coalescer being arranged adjacent to the second open separator end and in fluid communication with the axial flow separator; wherein (a) and (b) are arranged in sequence.

[0112] exist Figure 12A-12FIn the aspects shown, multiple coalescer arrangements 500A are arranged in one aspect of a coalescer system 2000A. The shown coalescer arrangement 500A includes (a) an inertial separator 200A, which includes (i) an eddy current generator 210, the eddy current generator including helical blades 211; and (ii) an axial flow separator 250, the axial flow separator including a hollow cylindrical axial flow body 255 having a first open separator end 261 and a second open separator end 262, an adapter / washer 290 (providing a front portion) attached to the first open separator end 261, the adapter / washer having a front surface 290A and a rear surface 290B, the front surface 290A including a shank 267A, and the rear surface 290B attached to the flow body 255 (see [link to relevant documentation]). Figure 13 and 14A -14B; Alternatively, you can use... Figure 4G-4I (a) An axial flow separator 250' is shown, comprising a hollow cylindrical axial flow body 255'; the axial flow separator is in fluid communication with the vortex generator 210; (b) a coalescer 300, the coalescer comprising a hollow porous coalescer medium 301, a first open coalescer end 311 and a second open coalescer end 312, and a closed coalescer end cap 360 located in the second open coalescer end 312, the end cap comprising a handle 365 (see...). Figure 4C and 13 The coalescer is arranged adjacent to the second open separator end 262 and is in fluid communication with the axial flow separator 250. According to the aspects shown for the inertial separator 200A, the separator 200A typically does not include a connector. The gasket in 290 forms an hermetically sealed seal around the first tube sheet between the first and second chambers, and the gasket in adapter / gasket 355 forms an hermetically sealed seal around the second tube sheet between the second and third chambers.

[0113] Regarding the coalescer 300 in arrangement 500A, the aspect shown in system 2000A also includes a curved plate 350' that contacts end plate 512 and second tube sheet 1250. The curved plate has a first end 351' that contacts the second tube sheet and a second end 352' that contacts end plate 512. The curved plate is arranged below the hollow coalescer 300 and around the lower portion of the coalescer, and partially around the side of the coalescer, to separate additional liquid (e.g., droplets) from the gas. The additional liquid is discharged from the outside of the coalescer and flows along the curved plate, and is transferred through discharge point 353' (located between the first end 351' and the second end 352') to a third collection tank 1300 (thereby minimizing or preventing the coalesced liquid from re-entering the clean gas flow and isolating the gas flow from each individual coalescer while guiding the gas flow upward). The gas is discharged from the pressure vessel along the hollow coalescer and through the outlet of the pressure vessel. Preferably, the curved plate covers 50-75% of the side of the coalescer (see...). Figure 12E-12F In some respects, the curved plate has a radius that varies along the length of the coalescer, and the frame has a larger radius R1 at the discharge point 353' and smaller radii R2 and R3 at ends 351' and 352', respectively (see...). Figure 12B It also includes an optional conduit 354A', which is vertically connected to guide the coalesced liquid from the coalescer to a third collection tank.

[0114] like Figure 12E-12F As shown, near the discharge point 353' of the curved plate 350', wherein the plate surrounds the lower portion of the coalescer and the side portion of the coalescer, the gap between the plate and the lower portion of the coalescer is smaller than the gap between the plate and the side portion of the coalescer.

[0115] and Figure 7D and 7F Compared to the snap-fit ​​element 555 shown, it is used to receive such as Figure 15D , 15F 16A and 16B (see also 16A and 16B) Figure 11A The snap-fit ​​feature 555' of the handle shown lacks a central support 557 and an opening 558, thereby providing surface area on the second plate 502 or end plate 512 for the second end 352' of the bent plate 350' to abut.

[0116] The difference between System 2000A and System 2000' is that System 2000A includes a third liquid port and a third liquid collection tank.

[0117] The filter-coalescer arrangement 500A shown is arranged in a coalescer system 2000A, shown as including a pressure vessel 1000", the pressure vessel including a pressure vessel inlet 1001, a pressure vessel outlet 1002, a first chamber 1100, a first liquid port 1101 for transferring separated liquid to a first collection tank 1102, a first tube sheet 1150, a second chamber 1200, a second liquid port 1201 for transferring separated liquid to a second collection tank 1202, a second tube sheet 1250, and a third chamber 1300 for transferring separated liquid to a second collection tank 1202. The liquid is transferred to the third liquid port in the third collection tank 1302; the first chamber 1100 includes a pressure vessel inlet 1001 and a first liquid port; the second chamber 1200 includes an inertial separator 200A and a second liquid port, wherein the first tube sheet 1150 separates the first chamber 1100 from the second chamber 1200; the third chamber 1300 includes a coalescer 300, a bending plate 350', a third liquid port 1301, an optional conduit 354A', and a pressure vessel outlet 1002, wherein the second tube sheet 1250 separates the second chamber 1200 from the third chamber 1300.

[0118] As described with respect to systems 2000 and 2000', in the illustrated aspect of system 2000A, the tube sheet has concentric holes, thereby dividing the interior of the pressure vessel into three chambers. A gasket at the first open coalescer end 311 provides a seal at the second tube sheet. In some aspects, the diameter of the holes in the second tube sheet is smaller than the diameter of the holes in the first tube sheet.

[0119] The pressure vessel 1000" has a first end 1000A before the pressure vessel inlet and a second end 1000B after the pressure vessel outlet, wherein the first end has a hinged openable hatch 1400 and the second end is closed.

[0121] Pre-filters may include depth filters (e.g., with the densest pore structure downstream and a coarser pore structure upstream) and / or include pleated and / or corrugated media. In some aspects, pre-filters may be arranged as media packages, and in others as corrugated pleated media packages. In some aspects, pre-filters comprise cellulose or glass fibers. While pre-filters primarily remove particulate matter from the fluid flow, in some aspects they pretreat the dispersed liquid phase by coalescing a portion of the liquid.

[0122] Typically, coalescers provide a minimum efficiency of 99.97% for 0.3-micron particles. Coalescers may comprise a combination of media and / or may be arranged as media packets, in some respects as corrugated media packets and / or pleated media packets. The coalescer is covered by a coalescer sleeve, such as a nonwoven media, which guides large droplets of coalesced liquid out of the gas flow.

[0123] Typically, a second inertial separator (if present) removes large droplets (e.g., >10 micrometers) from the airflow.

[0124] Typically, the collection tanks are removable for cleaning, and each collection tank has a valve for draining the collected liquid. Preferably, each has an automatic level sensor for actuating the valve.

[0125] Some components according to embodiments of the invention may be monolithic, preferably manufactured by additive manufacturing (sometimes referred to as "additive layer manufacturing" or "3D printing"). They are typically formed by repeatedly depositing metal powder bonded together with an activatable binder (e.g., binder jetting, sometimes referred to as "powder drop"), typically followed by agglomeration of the powder, for example, by sintering. Some components can be manufactured together in substantially the same amount of time in a continuous operation by additive manufacturing. Any suitable additive manufacturing equipment can be used, and various production 3D printers are suitable and commercially available.
