Abstract

PURPOSE:To carry out the conversion of a fluid position in a flow passage, by reversing a stream flowed through a pipeline to a tubular center in such a manner that the cross area thereof is held to an almost circular ring like form and the flow direction thereof is reversed. CONSTITUTION:Among tstreams of a fluid prior to a reversion, the fluid 6 flowed in the vicinity of a peripheral wall 33 is flowed in the vicinity of the bottom part 33 of a first member in a flow direction reversing part E to be reversed in a U-turn shape by mutual action with a fluid similarily reversed at the symmetric position and converted to a steam 6' in the vicinity of the center of the opening part 36 of a second member. On the other hand, a fluid 9 prior to a reversion is flowed in the vicinity of the flange 37 of the opening part 36 of the second member in the reversing part E so as to be abruptly reversed and subsequently converted to a steam 9' in the vicinity of the tubular wall of the tubular second member 35. As described above, a fluid in the center and the periphery of a pipeline is subjected to position conversion in good efficiency without generating pressure loss by a simple appratus.

る。In many industrial fields, fluids are conveyed using acoustic channels, and in the process, processing such as mixing and heating is carried out.
In the case where it is not necessary, the fluid is flowing in a non-turbulent state. However, in such a case, the fluid near the flow channel wall is generally difficult to mix with fluid in other parts.When subjected to treatment such as heating through the flow channel, in addition to being difficult to mix, Because the flow rate is slow, only the fluid near the channel wall is in contact with the heating wall for a long time, and is subject to excessive heating and deterioration.
-') % In severe cases, it can cause irritation. Such a case will be explained with reference to FIG. 1, which shows a conventional film forming process in which a film sheet is manufactured by melting a polymer. #! In Figure 1, the polyethylene terephthalate melt produced from the extruder lt is as follows:
The residence time in the filter device J is several minutes, whereas in some filter devices 1li3
Heated walls! The fluid portion 6 flowing close to the filter stays in the filter device for a long time due to the slow flow rate, etc.
For example, it takes several tens of minutes to get from the entrance section 7 to the exit section lK.

障欠歌を引起す。Therefore, depending on the temperature conditions, the polyethylene terephthalate in the fluid portion flowing near the heating wall may undergo thermal decomposition, generating low polymers that become impurities for the film sheet containing oligomers and monomers. One of the worst things about the city is that after leaving the filter unit 'RJ', the pipes are dropped and die! , and is cast from a die onto a casting metal drum (not shown), etc. However, the above-mentioned flow 6 is usually still on the pipe wall of pipe l-. Passing by, more Dai l! The inside also flows near the inner wall, and when it is cast to form the film sheet λQ, it forms the front and back surface portions of film sheet -O -7°-22, but the flow near the pipe wall is slow and Since the die and die are also heated, they receive excessive heat compared to other flow parts, which further promotes thermal decomposition. Monomer here,
Precipitation of oligomers, etc., adhesion of these precipitates to the metal drum for casting and other film sheet contact surfaces, recontamination and damage to the film sheet surface due to contamination, and p sublimation from the film sheet surface part in a high temperature atmosphere. Then, the recrystallized product of the secondary polymer may fall onto the film sheet, causing malfunctions in the tanks that reduce the quality of the film sheet as a product.

発し友。As a result of intensive research, the present inventors have found that the fluid near the wall of the channel and the fluid in the center of the channel are not mixed,
I discovered that all the problems mentioned above can be efficiently solved by swapping their positions with each other,
Such a position change by replacing the phase tiles of the fluid shapes the pipe flow, and then the pipe flow has a T-section that is approximately annular, and the flow direction is approximately opposite to the flow direction. All of the approximately circular flow is surrounded by the fluid of the approximately circular flow, and the fluid follows a reverse path, and the streamlines of the fluid are not significantly intersected in the entire path of the flow. What is achieved by the fi body reversal method, in which the sexual characteristic of A fluid inversion characterized in that the first member has a tubular shape that penetrates a part of the peripheral wall of the first member and ends at an opening facing the bottom surface of the first member.

ことができる。Regarding the fluid reversal method according to the present invention, which has been described above, it is common practice 1.
A fluid reversal device is installed and used at the position shown in section A in the figure. The pipe wall portion of the sea bream pipe that flows into the -IIi section A contains monomers and oligomers of low concentration produced by thermal decomposition as described above. Melt free of thermal decomposition products flows in the center of the pipe. These 411-component fluids pass through the t-A section of the apparatus according to the present invention Kt5, and after the A section, melt without pyrolysis products flows near the pipe wall of the conduit and near the inner wall of the conduit that follows. In the central part of the pipe and the subsequent part of the fluid flow path in the manifold part inside the gou, a melt containing low polymerized we, such as hexamers and oligomers, flows. If these melts are spilled onto a casting support such as a metal drum or belt for casting and form a film sheet, thermal decomposition products will be present on the front and back sides of the melt. Is the film sheet structured such that the film sheet has a structure in which the polymer containing heat components such as monomers and oligomers is located in the center of the thickness direction of the film sheet, and the normal polymer wraps around the part containing impurities? In particular, when the surface quality is required to be free from defects, such as for example in photographic films, a sufficiently satisfactory quality can be obtained. Furthermore, although the inside of the film sheet contains some monomers and oligomers, the surface portion has a completely positive surface property, so sublimation of the monomers and oligomers also occurs. It is also possible to prevent malfunctions such as objects attached to the seat surface.
