, Description:TECHNICAL FIELD
[0001] The present disclosure relates to the field of fluid mixers used for mixing various fluids. The present disclosure more particularly relates to PTFE Lined Reducing Tee.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Reactive multicomponent compounds are used in diverse ways as, e.g., two-component glues, two-component mortar masses for securing structural components, anchor rods and the like in solid constructional grounds such as brickwork, concrete or similar hard bases, or for forming fire-protection foams or constructional foams used for filling of breakthroughs, lead throughs, and openings in walls, ceilings, and floors of buildings or for forming of windows or doors of buildings. Such multi-components compounds, in particular, those used on a building site, are usually available in multi-chamber containers or vessels in which components that react with each other, are stored separate from each other, without a possibility of a reaction there between. During use, the different components are fed from the separate containers, e.g., by being squeezed-out with an ejector device, and are mixed with each other. Thereafter, the mixture is introduced into the use region, e.g., a dowel bore.
[0004] For mixing different components of compounds, usually static mixers are used in which there is arranged, in a jacket, a mixing element that provides for a homogeneous intermixing of components of a mixture by using the flow energy of the components of a multi-component compound which are fed into the static mixer under pressure. Here, mixing devices are used that have either a movable container or a movable mixing tool and in which intermixing of the mixture takes place as a result of the effect of the movement energy of the mixture that continuously flows through the static mixer, with the mixing element or elements, which are located in the flow path, effecting an intensive intermixing of the mixture. As mixing elements, manifolds, expansion elements, injectors, counterflow conduits, swirling elements, guide plates, inserts of different types, which provide for an intensive intermixing due to their shape, are used.
[0005] Both the jacket and the mixing elements of such static mixers can be formed of different materials, e.g., metal, glass and, in particular, plastic materials. In particular, removable mixing elements of different shapes, which are used for intermixing and feeding of the multi-component compounds in form of mortar mass, constructional foam, etc., are formed of a plastic material.
[0006] Static mixers have become standard equipment in the process industry. They are used in continuous processes as an alternative to conventional agitation since similar and sometimes better performance can be achieved with lower cost. Motionless mixers typically exhibit lower energy consumption and reduced maintenance requirements because they do not include moving parts. They require smaller space, lower equipment cost, and no power except pumping. They can provide homogenization of feed streams with a minimum residence time and can be manufactured from most materials of construction so as to meet various standards and to adapt with harsh working conditions.
[0007] Static mixers now find very wide use in mixing liquid to liquid, liquid to gas or even gas to gas. As explained above their main advantage is that they use no moving parts but instead use the energy of the flow stream to create mixing between two or more fluids. They are now manufactured in a wide range of range of materials, including stainless steel, other Exotic metals PTFE and FRP the latter two typically being used as lining materials in the process fluid stream pipeline or the mixing fluid stream pipeline.
[0008] Before the mixing elements portion of a static mixer the mixing fluid is introduced to the process fluid in an inlet manifold. Both the process fluid as well as the mixing fluid is normally under pressure and the mixing fluid is introduced in the process fluid by using an inlet manifold of a tee profile, generally of a reducing tee profile. The mixing fluid from the branch side of the tee falls directly in the stream of the process fluid that is being fed from the main side of the tee and impinges on the walls of the pipeline carrying the main fluid. Such intermixing generates high amounts of heat due to exothermic reactions, which can damage the wall round the tee point. Such heat generated is close to the process fluid pipeline where the mixing fluid impinges. Hence the wall of the process fluid pipeline or the PTFE liner therein gets damaged very quickly.
[0009] There is a need in the art for a device that reduces damage to the area around tee point due to heat generated due to exothermic reaction, thereby increasing the longevity of the tee point and PTFE liner of the process fluid pipeline or the process fluid pipeline itself.

DETAILED DESCRIPTION OF THE INVENTION
[0026] The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.
[0027] Each of the appended claims defines a separate invention, which for infringement purposes is recognized as including equivalents to the various elements or limitations specified in the claims. Depending on the context, all references below to the "invention" may in some cases refer to certain specific embodiments only. In other cases it will be recognized that references to the "invention" will refer to subject matter recited in one or more, but not necessarily all, of the claims.
[0028] Various terms as used herein are shown below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.
[0029] The term ‘exothermic reaction’ in the instant disclosure means a chemical reaction that releases energy by light or heat.
[0030] The present invention relates to the field of fluid mixers used for mixing various fluids. In particular it relates to a device to reduce heat generation due to exothermic reaction close to the walls of the main inlet pipe of a fluid mixer. An embodiment of the present disclosure provides a PTFE lined reducer tee having inbuilt elbow liner. The PTFE lined reducer tee includes a main inlet pipe to supply a first fluid (also interchangeably referred as process fluid), and a feed line ( also interchangeably referred as feed pipe ) having an elbow profile opening inside the main line to supply a second fluid (also interchangeably referred as mixing fluid )that mixes with the first fluid. As one may appreciate, by providing elbow profile to the feed line, damage caused to the main inlet pipe due to exothermic reaction near the walls of the main inlet pipe gets minimized as the heat generated by the exothermic reaction gets distributed.
[0031] In another aspect, the fluid mixer can include at least one mixing element and an inlet manifold configured to carry the mixing fluid and the process fluid to the at least one mixing element, wherein the inlet manifold can be configured with a feed pipe operatively coupled to an elbow opening inside the main inlet pipe , said elbow configured to disperse the mixing fluid away from the walls of main inlet pipe of the inlet manifold thereby reducing the heat generated due to exothermic reaction close to the said walls. In an aspect mixing element can be static.
[0032] In yet another aspect, the elbow can be configured to allow smooth mixing of the mixing fluid with the process fluid of the fluid mixer. In an aspect, the inlet manifold can have a reducer tee profile.
[0033] In yet another aspect, the elbow, main body of the inlet manifold and the pipe on the feed side of the inlet manifold or any combination of these can be PTFE lined.
[0034] While the invention has been disclosed hereunder using an example of a static mixer, it can apply for any kind of mixer wherein an inlet manifold is being used.
[0035] FIG. 1 illustrates an inlet manifold of a PTFE lined fluid mixer as presently manufactured. The inlet manifold has a reducer tee shaped profile with a process fluid main inlet on the main side of the tee and a mixing fluid inlet on the branch side of the tee. As illustrated, the main side of the tee comprises a main inlet pipe 102, also referred interchangeably as main line that has a PTFE lining 104, and branch side of the tee comprises a feed pipe 106, also referred interchangeably as feed line, with PTFE lining 108.
[0036] As shown, when a mixing fluid stream 110, carrying second fluid, is fed into feed pipe 106 it directly falls on the walls of the main inlet pipe 102 near the tee point on zone illustrated as A, while at the same time mixing with a process fluid stream 112, carrying first fluid, before being carried away to a mixing element further downstream for proper mixing. This mixing of the two fluids in the inlet manifold generates strong heat due to exothermic reaction that can damage the area around tee point or A, due to concentrated heat close to area illustrated as Zone A, as large amount of the mixing fluid reaches there and reacts with the process fluid before being dispersed. Hence the PTFE lining 104 at Zone A of main inlet pipe 102 or the main inlet pipe 102 itself can be damaged in a very short while
[0037] FIG. 2 is an exemplary representation of an improved inlet manifold of a fluid mixer employing a feed pipe having elbow profile designed in accordance with an embodiment of the present disclosure. In an aspect, the invention of the present disclosure relates to a PTFE Lined Reducer Tee with inbuilt special elbow liner.
[0038] In an aspect the inlet manifold of the proposed disclosure can be of a reducer tee profile with a process fluid main inlet on the main side of the tee and a mixing fluid inlet on the feed side of the tee. In another aspect, the main side of the tee can comprise a main inlet pipe 102 that can have a PTFE lining 104. In this fashion the inlet manifold can have a PTFE lined body. In an aspect, the branch side of the tee can comprise a feed pipe 202 with a PTFE lining 204 operatively coupled to a PTFE lined elbow 206 opening inside the main inlet pipe 102. In another aspect, the feed pipe 202 can be open inside the main inlet pipe 102 using the PTFE lined elbow 206 as illustrated. The elbow 206 helps to avoid damage around the zone A, due to exothermic reaction, as produced heat gets distributed.
[0039] In yet another aspect, PTFE lined elbow 206 can be configured to direct the stream of mixing fluid alongside that of the process fluid and away from the walls of the main inlet pipe 102. The PTFE line elbow 206 of the feed pipe 202 can be configured to have an opening the inside the main inlet pipe 102 so as to discharge the mixing fluid in the same direction as that of the process fluid and away from the wall of the main inlet pipe 102.
[0040] Fig. 3 illustrates how the device of the present disclosure avoids heat generation close to zone A.As illustrated, the mixing fluid stream 110 can be made to flow from the feed side of the tee using PTFE lined feed pipe 202 having PTFE lined elbow 206 in a direction aligned with that of process fluid stream 112 and away from the PTFE lined walls of the main inlet pipe 102.
[0041] In this fashion, exothermic reaction close to zone A can be reduced and so heat generation close to the walls of the main inlet pipe 102 of the fluid mixer can be reduced.
[0042] In another aspect, using PTFE lined elbow 206, the mixing fluid stream 110 can be aligned with the direction of process fluid stream 112 and so the mixing fluid can be introduced smoothly into the main fluid.
[0043] In another embodiment of the disclosure, the component or the parts of the present disclosure can be coated, painted or coloured with a suitable chemical to retain or improve its properties, or to improve the aesthetics or appearance.
[0044] In an embodiment of the disclosure, the components of the present disclosure can be connected or arranged by using any suitable method and may include without limitation use of one or more of welding, adhesives, riveting, fastening devices such as but not limited to screw, nut, bolt, hook, clamp, clip, buckle, nail, pin, ring.
