Description

</ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; More particularly, the present invention relates to a mass transfer or energy transfer module that is comprised of a mass transfer or energy transfer, a reusable bowl, a reusable manifold, and a The mass transfer or energy transfer g, the material is re-used with the bowl and the manifold is connected to the reusable attachment means. Xin [Prior Art] Various modules are used to achieve mass transfer or energy transfer between the two fluids. The representative module includes a degasser wherein one fluid comprises a liquid containing a gas and the other fluid is a gas at sub-atmospheric pressure, wherein the two-stream system is separated by a gas permeable membrane. The other module is a gasification a wherein one of the fluids is a gas at superatmospheric pressure and the second fluid is a liquid in which the gas is soluble, wherein the fluid system is separated by a gas permeable membrane. The third module is a heat exchanger wherein the hot fluid and the cold flow system are separated by a non-permeable, thermally conductive material. The mass transfer or energy transfer module can include a manifold, a bowl for containing a fluid, and a bowl for containing a second fluid. Therefore, when the mass transfer or energy transfer module is constructed, the bowl and the bowl are respectively fixed to and sealed to the occupant, and in addition, the transfer or energy transfer is removed from the head. The bowl is hidden with the bowl. This separate removal requires that the bowl be moved - generally greater than the entire length of S, thereby exposing the file to allow it to be removed. Thereafter, the exposed 101730.doc 1273917 e is removed by hand or by hand. Since the bowl must be moved to the length of the bowl, the space in which the bowl and the bowl are positioned internally must accommodate this removal step. It has been proposed in U.S. Patent No. 5,114,572 to provide a filter assembly that cooperates with a bowl to produce a filter bowl-bowl configuration that can be removed from the manifold as a single unit. This filter assembly is not used for mass transfer or energy transfer between two fluids. It is used to filter fluids. The filter tether is connected to the bayonet by a bayonet connection in the recess in the inner surface of the bowl

Bowl. The bayonet connections, such as are integrally formed with the crucible by molding into a single unit. When configured as such, it can only be used with a bowl configured to receive a bayonet. This is undesirable because it prevents such a configuration from being used with currently produced bowls that are configured to not accept the crucible. In this way, the market for the E thus configured is severely reduced. In addition, the bayonet connection is positioned below the top surface of the top surface such that it fits within the bowl and is also positioned in the recess below the top surface of the crucible. When the bayonet is so positioned, the positioning in the recess is made more difficult due to reduced visibility. Therefore, there is a need to provide - mass transfer or energy transfer media or hiding in a plurality of bowls for different configurations. In addition, it is desirable to provide this E which includes - a connecting member between the weir and the body, the bowl having a member that is immovable relative to (iv) during mass transfer or energy transfer using the two fluids. In addition, it is desirable to provide "with a clearly visible connecting member that facilitates the attachment of the E to the bowl. It will facilitate the insertion of the filter cartridge into the bowl transfer or energy transfer module and will reduce the installation quality. 101730.doc 1273917 SUMMARY OF THE INVENTION According to the present invention, there is provided a 4 il ffi ^ ha mass transfer or energy transfer module using a two fluid comprising a manifold, and - mass transfer or energy transfer g and bowl combination 'where the crucible is locked with the bowl as a single

Piece) is installed and removed from the manifold. The f-transfer or energy transfer (F) includes at least a fluid passage for fluid communication between the manifold and the interior of the g. The outer surface of the fluid passage includes two flat surfaces that are tight with the key

The dense fit flattens the parallel surface such that the key is slidably fitted to the fluid passage. In the first embodiment, the 'key has a bayonet, and the bayonet fits

The slot in the bowl is used to achieve a connection to the bowl. In a second embodiment, the key is provided with a hook-like member that snaps over the open lip of the bowl to thereby achieve a connection to the bowl. The key can be removed from E such that (d) can be used with conventional bowls that are not fixed for use or with the bowls used in the mass transfer or energy transfer modules of the present invention. The (4) key to the bowl and the bayonet or key and hook element allow the g and bowl to be removed from the manifold as a monomer. [Embodiment] The outside of the ''匣 or the inside of the E is introduced into the degree via the manifold. The fluid in the bowl can be removed from the bowl via the manifold or directly from the bowl. In any aspect, the invention provides a mass transfer or energy transfer port and a mass transfer or energy transfer module formed by a manifold, the S and a bowl. Manifold 2 provides fluid passage for the first fluid feed into the crucible, optional first fluid removal from the crucible, and second fluid feed and second fluid removal from the bowl. Fluid removal from the E or bowl is achieved via the deviation f. The fluid feed can provide a seal from the 101730.doc 1273917 to prevent the first fluid from mixing with the second fluid without energy or mass passing through the crucible. The mass transfer or energy transfer and bowl are constructed such that they are sealed by a manifold or from contact with the manifold to form a single member. The two end caps are used to seal £, at least one of which has a fluid passage. The first-class body passage has two opposing substantially parallel flat 1 surfaces on the outer surface of the crucible. The cymbal has a button that is slidably fitted to the two flat surface φ faces to be positioned around the fluid passage of the cymbal. The fluid channel can be used as an inlet or outlet for the crucible. The key is configured to lock the file to the bowl. In one embodiment, the bowl and the tether are joined together by a barb on the key that fits into the slot on the inner surface of the bowl. In a second embodiment, the key is joined to the bowl by snap fit onto the open top lip of the bowl. The flat surface on the fluid passage prevents the key from rotating relative to the weir. After the mass transfer or energy transfer module is used, the bowl and crucible are removed from the manifold as a single piece construction rather than as two separate pieces. Because the bowl and the enamel are removed, there is no need to remove from the bowl. Therefore, it is desirable to provide a space that is substantially equal to the sum of the lengths of the bowl and the bowl to remove the flaws. It is only necessary to provide a space that is substantially as long as the length of the bowl. This allows us to install the flaws of the present invention in a smaller space than the space required for the uranium module. In addition, since the tether is removed with the bowl, it is not required to be manipulated by hand or by hand tools. In this way, the likelihood of contacting the fluid within the article with the worker is substantially reduced. The bowl may optionally contain a discharge port for removing fluid from the bowl. Referring to Figure 1, a mass transfer module 10 includes a manifold 12, a bowl 14 having a port 107730.doc 1273917, and a mass transfer port 16. The mass transfer port 16 can be a film such as a gas permeable folded film 23. This mass transfer enthalpy can be used as a degasser for liquids or as a gas contactor for achieving dissolution of a gas in a liquid. Suitable films are made of poly(tetrafluoroethylene-co-perfluoro(alkylvinylether)) (PFA) or poly(tetrafluoroethylene-co-hexafluoropropylene) as disclosed in U.S. Patent No. 4,990,294. (tetrafluoroethylene-co-hexafluoropropylene) (FEP) formation &quot;Hai patent is incorporated herein by reference. These films can be used to liberate gas from liquids, "degassing" or to add gaseous substances to liquids. For example, ozone is added to very pure water used to clean semiconductor wafers. Threaded ring 18 is positioned in the bowl. The outer surface 2 of the body 14 is plied and retained thereon by beads 22 extending around the circumference of the bowl 14 and the lip 24. By controlling the size and flexibility of the bead 22 The ring 18 can be slid over the beads 22 to clamp the % 18, or the beads 22 can be formed on the bowl μ after the ring 18 is positioned as shown. The ring 18 is generally fixed relative to the bowl 14 Its position, that is, it cannot move any substantial distance along the length of the bowl. When the thread is "pushed" with 28, the ring 18 carries or drives the E 16 in firm contact with the manifold 12 to achieve the use of the 〇-shaped ring Seal of ^13. Conversely, when the ring 18 is rotated to drive the threads 26 and 28 apart, the carrier or drive raft 16 is completely separated from the manifold 12. The sealing of the bowl 14 to the adjoining manifold 12 is achieved by the 0-ring i 7a. The moving bowl is vertically contacted with the manifold 12 without rotating the bowl 14. The rim 6 is attached to the bowl 14 by a flange 101730.doc 1273917 15 that is in close engagement with the slot 32 in the collar 34 of the key 3. Screw the collar % into the bowl μ by screw (4). The collar 34 extends around the entire inner circumference of the bowl 14. Alternatively, the bowl and the collar may be formed, for example, by molding a single body in the shape of a bowl 14 and a collar. The key 30 is fitted to the outer surface of the fluid passage positioned on the 16 The two flat surfaces are 38 and 4 on the top. Fluid passage 42 includes sealed jaw rings 11 and 13. Since the flange 15 does not extend around the entire circumference of the key 3〇, the fluid can cause the key 3〇 to flow into the manifold 12 through the bypass. When the module 10 is used as a degasser, a vacuum is drawn at the inlet 44, and the liquid to be degassed is introduced via the inlet 9 and the liquid is removed via the passage 8 and the outlet 46. When the mold set 10 is used to introduce a gas into the liquid, the super-atmospheric gas enters the inlet 44 and the liquid enters the inlet 9 and is removed via the outlet 46. The structure of the key 30 will be more fully described with reference to FIG. The structure of the collar will be more fully described with reference to FIG. Referring to Figure 2, the module π includes a manifold 19, a weir 21 and a bowl 25. The g2i is attached to the bowl 25 by a flange 27 on the bowl 25 having the key 3 of the slot 29. The key 31 fits around the fluid passage 33 to provide a strong connection between the key 31 and the fluid passage 33 while avoiding significant blockage of the passage 33. The passage 33 is connected to the inlet 35. The passage 33 is connected to an inner cavity of a plurality of hollow fibers 37 made of a non-porous thermally conductive material such as stainless steel. The first fluid can be introduced into the hollow fiber 37 via the inlet 33 via the inlet 35 and then the weir 21 can be withdrawn via the outlet 39. The second fluid can be introduced via the inlet 41 onto the outer surface of the hollow fiber 377 and then via the outlet 43. The module 7 of Figure 2 can be used to achieve heat exchange between the two fluids. The threads 26 and the lip 24 act to interact with a rotatable ring (Fig. 1), mutual 101730.doc -10- 1273917, in the same manner as described above for Fig. 1. An optional exhaust can be provided Port 44. Referring to Figure 3, the collar 34 includes two slits 41 and two vertical extensions 43. Each of the vertical extensions 43 includes a slot 32 (one of which is not shown). The slot 32 is fitted with The angle of the accommodating flange 15 (Fig....opposed by the slot 32 depends on the flexibility of the material used to make the key 30 and the collar 34. The key 30 and the collar 34 are relatively flexible perfluorine ( When the alkyl vinyl sulphide (pFA) dimer is formed, the slot 32 is at an angle of at least about 15 degrees, preferably between about 3 degrees and about 45 degrees. When the key 30 and the collar 34 When made of a relatively hard material such as high density polypropylene, the angles may be approximately - half for the angle of the pFA. This angular dimension of the exemplary materials provides between the flange Μ and the slot 32. The desired contact surface is such that the key 30 does not separate from the ferrule 34 during use of the module 1. The collar 34 may optionally include a detent 45, such locators The optional vertical extension/sleeve 34 on the outer surface of the mating and receiving flange 15 also includes optional vertical slots 17 that allow fluid to escape between the collar 34 and the manifold 12. 4. The bowl and collar construction of the present invention is shown. The collar % is screwed into the bowl. The collar and bowl 14 can be molded into a single body. The bowl 14 includes a support lock ring 18 (Fig. 1} a plurality of baffles 5 〇. The bowl μ includes an inlet 1 7 〇 In one aspect of the invention, the key has an outer surface configuration, and the outer surface is configured with a collar attached to the bowl The inner surface is configured to be tightly fitted so that the attached raft is centered within the bowl. When the key is rotated into the collar, the ridge is placed in the center of the bowl to allow the key to be flat with the collar. / month with σ. The outer surface configuration of the key includes a small groove. Although the surface is equipped with 101730.doc 1273917 is not required by the present invention, if there is no additional surface configuration, the key will slide from the side within the collar To the other side, thereby increasing the difficulty of the key engaging the collar. Referring to Figures 5 and 6, it is shown An alternative configuration for joining the crucible to the bowl. The key 60 is provided with two prongs 62 that are slidably coupled to fluid passages in contact with the two planar surfaces 64. 42. The two planar surfaces are substantially parallel to each other in the same manner as described above for Figure 1. As shown in Figure 6, the hooked prongs 66 fit over the lip 68 of the bowl 14. The key 60 is also provided with a lever 67 that is pivoted such that the hand force on the lever 67 allows the prong 66 to move into contact with the bowl 14 or from contact with the bowl 14. Although two The opposing attachment elements (flanges or prongs) are used to describe the keys of the present invention, but it will be appreciated that the keys can be provided with more than two attachment elements. In order to maintain the axial alignment of the crucible with the bowl, at least two attachment elements are required. Since the key of the present invention can be removed from the crucible, the crucible of the present invention can be utilized with the bowl of the present invention described above, or with a bowl of conventional size. The removable button allows the insertion without the key to be inserted into a conventional bowl without a slot on its inner surface, otherwise the flange on the key will cause the entire footprint of the key and the key to be larger than that of the conventional bowl. diameter. In this way, it is again allowed to reduce the amount of sputum required to accommodate the conventional bowl and the bowl of the present invention. In use, the lever 67 of Figure 5 is subjected to hand pressure whereby the R head 66 is moved away from the prong 62. The crucible 16 falls into the bowl 14 and releases the hand pressure on the lever 7 and thereby secures the prong 6 6 to the top of the bowl. 101730.doc -12- 1273917 edge 6 8 to key 6 0 Fixed to the bowl 14. The embodiment of Fig. 2 is inserted into the collar of Fig. 3 by first aligning the flange 15 with the knife edge 41. The key 3G is then rotated such that the flange 15 fits into the slot 32, thereby securing the cymbal 16 to the collar 34. Referring to Figures 7 and 8, the key 70 includes a recess 72 that fits snugly against the surface 78 of the collar. Although the key 7 includes the boss 82, it is not necessary for the function of the recess 72. The use of the bosses is described below. Referring to Figures 9, 10 &amp; U, the collar 84 includes two opposing slots % and 88 that are raised when the key 90 is rotated into position in the collar 84. Fitted in the slots. The slots are caused to expand away from each other by bringing the bosses 82 into contact with the inner surface of the collar 84. The distance between the outer surfaces of the bosses 82 is slightly greater than the distance between the opposite inner surfaces of the collars 84. The slots 86 and 88 extend through the thickness of the collar 84. The slots 86 and 88 are mated with the raised portions 82 on the key 90 to provide an improved fit between the collar 84 and the key 90. When the key is rotated to the proper position until the raised portion 82 fits into the open slots 86 and 88, the raised portion 82 is configured to cause the mating slots 86 and 88 on the collar 84 to expand outwardly. Upon mating, the slots 86 and 88 contract toward each other and thus overlap the boss 82, thereby making it more difficult for the key 9 to be detached from the collar 84 during use.
