Description

  The present invention has an internal structure partitioned into a large number of flow paths, and includes a liquid distributor disposed at an upper portion and a liquid collector disposed at a lower portion, and mass transfer, heat exchange or mixing between a gas and a liquid. The present invention relates to a gas-liquid contact mechanism in a device that performs the above.

Conventionally, a regular filler as shown in a partial sectional view in FIG. 11 is known as a regular filler in this type of apparatus. This regular packed body a is formed of a porous thin plate that is formed into a plurality of corrugated shapes and alternately stacked at a predetermined interval below a liquid distributor disposed at the upper part of a packed packed column constituting the apparatus. The sheets b are arranged parallel to each other so as to extend in the diagonal direction of the corrugation, and are arranged in multiple layers so as to be inverted in the reverse direction and extended in the diagonal direction at the position contacting the inner wall of the packed tower. It will be. The liquid that freely falls as droplets from the liquid distributor flows down along these thin sheet sheets b, and wets the surface of the sheet b. On the other hand, the gas enters and rises from the gas inlet at the bottom of the tower, passes through the regular packing a, and exits from the gas outlet at the top of the tower. While the gas passes through the regular packing a, gas-liquid contact is performed, and desired mass transfer, heat exchange, or mixing is performed.

  The problem with the conventional ordered packed body is that, firstly, a part of the sheet b constituting the ordered packed body a contacts the inner wall c of the packed tower at its bent edge. The liquid flowing down through these sheets b moves to the inner wall c, and a large portion of the liquid flows back along the inner wall c as a wall flow without returning to the sheet b. On the other hand, the gas rising in the packed tower has a parabolic flow velocity distribution in the radial direction of the cross section, the flow velocity at the center is the fastest, and when approaching the wall surface, the flow velocity approaches zero due to viscosity. Therefore, the rising gas tends to flow through the center of the tower, and almost no gas flows through the wall surface. Due to this gas drift, the wall flow of the liquid is less in contact with the gas than the liquid flowing in the center, resulting in non-uniformity in the reaction to be achieved as a result of non-uniform gas-liquid contact.

  The second problem of the conventional regular packing body is that in this regular packing body a, the sheet b is arranged obliquely, so that the pressure loss is high, the energy consumption is correspondingly high, and the efficiency is low. is there.

  The third problem of the above-mentioned conventional regular packing is that the upper limit of the gas load is kept relatively low because the device cannot be operated soundly when the gas load is increased.

  That is, when the flow rate of the liquid supplied from the liquid distributor at the top of the tower is increased, the descending liquid gets wet while spreading the surface of the packing, but when the liquid volume is further increased, the liquid film becomes thicker and partially Leaves the liquid film as droplets. Therefore, if the flow rate of the gas added from the lower part of the tower is increased while the liquid is flowing from the top, the liquid film surface is easily disturbed by the high gas flow velocity and becomes droplets, which are blown upward by the gas. As a result, a certain component is concentrated and the descending liquid is caused to flow backward, and the reaction efficiency is deteriorated. The phenomenon that the gas blows off the droplets is often seen until the liquid falls from the liquid distributor at the top of the tower to the top of the regular packing or in the vicinity of the liquid collector provided at the bottom of the tower. For example, it behaves like raindrops from rain gutters blown in all directions by strong winds during typhoons. The liquid distributor is for supplying the liquid uniformly to the regular packed body in the cross-sectional direction of the tower, and the above behavior that blows off the droplets lowers the performance of the packed tower, and therefore must be prevented as much as possible. On the other hand, the liquid collector must collect the separated liquid without blowing it upward as droplets. The above-mentioned conventional apparatus is an effective countermeasure against the scattering and blowing up of liquid droplets in the space between the liquid distributor and the regular packing body and between the regular packing body and the liquid collector due to the increase in the gas flow rate. Does not have

  Regarding the third problem, a liquid distribution / collection mechanism described in Patent Document 1 has been proposed to solve this problem. In this mechanism, as shown in FIG. 12, a liquid distribution rope h formed by twisting a plurality of strand portions m to a nosul g of a liquid distribution pipe f attached to a liquid distributor e of a packed tower d is connected. The liquid distribution rope h is connected to the regular filler i. The liquid is distributed from the liquid distribution pipe f to the regular packing body i through the liquid distribution rope h and the strand part m branched in two, and the liquid which has completed the gas-liquid contact is formed by twisting a plurality of strand parts n. The liquid collecting mechanism k including the liquid collecting rope j is transferred to the liquid outlet l. Therefore, in this apparatus, the liquid is expected to be reliably transferred to the regular packing body and taken out from the regular packing body without being blown upward even at a high gas velocity.

  This liquid distribution / aggregation mechanism seems to be an ideal liquid distribution method that solves the third problem in theory, but as a result of the experiment, the two strand portions m constituting the liquid distribution rope h are Even if it is composed of the same number of wires, each wire flows first due to a slight difference in twist angle between the wires or a difference in the compatibility of the liquid based on the difference in the surface roughness of each wire. The flow of liquid is not uniform for each wire, and the wire that flows most easily has a liquid path ahead of the other wires, and the subsequent liquid follows and does not flow along the other wires through this liquid path. Since there is a tendency, the liquid flowing from the liquid distributor to the liquid distribution rope h does not necessarily flow evenly to the two strand portions m branched from the liquid distributor, and as a result, the liquid flowing to the regular packing i also becomes non-uniform and complete. Inability to make proper gas-liquid contact It was found.

  As an apparatus for solving the above-mentioned problems, Patent Document 2 is a regular packing body that constitutes an internal structure, and is composed of a plurality of packing body constituent elements. Each packing body constituent element includes an inner wall of the apparatus and an adjacent packing body.

According to this device, each filler component extends vertically in parallel to each other in a non-contact manner with the inner wall of the device and adjacent filler components, so that it flows down from the liquid distributor to each filler component. The liquid moves to the inner wall of the apparatus and does not flow into the wall, and moves to the adjacent packing component and flows to the liquid collector without causing a non-uniform liquid flow. As a result, the amount of liquid flowing through each filler component is uniform, and uniform gas-liquid contact is achieved. In addition, since each filler component extends in the vertical direction in the apparatus, pressure loss can be minimized. Furthermore, since the liquid distributor and the regular packing are directly connected by an adapter, and the regular packing and the liquid collector are also directly connected by the collector, the liquid distributor is regularly connected to the regular packing by the increase in the gas flow rate. It is possible to prevent the droplets from being scattered and blown up in the space between the filler and the liquid collector.

FIG. 1 is a schematic longitudinal sectional view showing an entire apparatus in which the gas-liquid contact mechanism is used. FIG. It is a perspective view which shows the wire-shaped filler component of a contact mechanism.

  In FIG. 1, a packed tower 10 that accommodates a regular packed body that makes gas-liquid contact for mass transfer between gas and liquid is a cylindrical tower that is long in the vertical direction. A plurality of tubular liquid distributors 2 extending in the vertical direction for distributing the liquid to the regular packing body below are arranged. Liquid is supplied to the liquid distributor 2 via the liquid supply pipe 11. A plurality of tubular liquid collectors 3 for collecting the liquid that has completed gas-liquid contact are disposed in the lower portion of the packed tower 10.

A plurality of wire-like collectors 7 formed integrally with each filler component 6 are disposed.

  The ordered packing 5 has a cross-section in which a number of vertically extending wire-shaped packing elements 6 are maintained at a predetermined distance from each other, that is, adjacent packing elements 6 are parallel to each other in a non-contact state. Are arranged so as to form rows and columns. Each packing component 6 is arranged so as to maintain a non-contact state with the inner wall of the column 10.

  In this embodiment, each wire-like adapter 4 that connects the liquid distributor 2 and the regular filler 5 and supplies the liquid from the liquid distributor 2 to the regular filler 5 has a one-to-one correspondence with any of the filler components 6. It is formed integrally with the relationship. Each adapter 4 is directly connected to the tubular liquid distributor 2 without branching from other adapters and without branching other adapters. Therefore, a plurality of adapters 4 integrated with each of the plurality of filler components 6 constituting the aggregate are inserted and held in a bundled form inside the lower end portion of the tubular liquid distributor 2. . Each adapter 4 is inserted in a state where a certain gap is formed between adjacent adapters, and the liquid is gently bundled so that the liquid flows down from the entire circumference of each adapter 4 along the adapter 4.

In addition, the form of the wire is not particularly limited, such as a wire, a twisted yarn, a monofilament, and a wire, but a twisted or twisted wire material such as a wire made by twisting a plurality of thin steel wires is a liquid. It is preferable because the movement of the liquid is promoted by flowing through a space between a plurality of yarns or wires constituting the twisted yarn by capillary action. In this embodiment, as a preferred example, a wire obtained by twisting two steel wires made by twisting four steel wires each having a diameter of 0.25 mm is composed of one filler component 6, adapter 4, and collector 7. Can be used as

FIG. 2 is a perspective view showing a filler component 6 composed of three wires as an embodiment of each wire-like filler component 6 forming the regular filler 5.
Each filler component 6 has a structure in which three wire wires are alternately repeated in a ring shape portion and a termination portion. That is, as shown in the enlarged view of FIG. 3, the two outer wires 6a and 6b of each of the filler components 6 are bent into arcs projecting outward to form a ring. The wire 6c extends linearly in the vertical direction. A ring-shaped portion 15 is formed by these three wires 6a, 6b and 6c.

  Directly below the ring-shaped portion 15, outer wires 6 a and 6 b are twisted around the central wire 6 c to form a collecting portion 17.

  The outer wires 6a and 6b twisted at the concentrating portion 17 are opened directly under the concentrating portion 17 and bent into an arc shape, so that the ring-shaped portion 15 is formed again.

To do.

FIG. 4 is an enlarged view similar to FIG. 3 showing a filler component 6 composed of two wires as another embodiment of each wire-like filler component 6 forming the regular filler 5.
Each filling body component 6 has a structure in which two wires repeat alternately in a ring shape portion and a termination portion. That is, as shown in FIG. 4, the two outer wires 6a and 6b of each filler component 6 are bent into arcs projecting outward to form a ring. In this embodiment, one central wire 6 is not used. A ring-shaped portion 15 is formed by these two wires 6a and 6b.

  Outer wires 6 a and 6 b are twisted immediately below the ring-shaped portion 15 to form a collecting portion 17.

  The outer wires 6a and 6b twisted at the concentrating portion 17 are opened directly under the concentrating portion 17 and bent into an arc shape, so that the ring-shaped portion 15 is formed again.

  Thus, each filler component 6 can have a structure in which the ring-shaped portions 15 and the concentrating portions 17 are continuously and alternately formed in the vertical direction.

Next, the operation of the gas-liquid contact mechanism using the filler component 6 made of the above two wires will be described.
According to the above embodiment, each filling body component 6 constituting the gas-liquid contact mechanism includes the two wires 6a and 6b, and the two wires are alternately formed by the ring-shaped portions 15 and the collecting portions 17 respectively. Since it has a repetitive structure, the liquid flowing down through this becomes a thin liquid film covering the circular space in the ring in the link-shaped portion 15, the surface area of the liquid is maximized, and the gas rising from below is most effective. Contact will be made. Next, the liquid forming the liquid film flows down from the ring-shaped part 15 of the wire to the concentrating part 17 directly below, collects the liquid here, and further flows down to the ring-shaped part 15 immediately below to cover the inner space of the ring again. A liquid film is formed, and thereafter this operation and shape change are repeated alternately. In this way, the liquid film is renewed continuously and the maximum gas-liquid contact effect is achieved.

  Further, since the streak-like wire has no branching in the middle, there is little pressure loss. Also, the high performance results in very low pressure loss for performance.

  Further, according to the embodiment using the filling body component 6 composed of the above-described three-strand wires, there are the same effects as the embodiment using the two-strand wires, and the outer two-strand wires forming the ring Since a straight third wire is arranged in the middle of the wire, this third wire reinforces the ring and functions to prevent the damage of the circular liquid film, thereby achieving more efficient gas-liquid contact.

Next, a method of manufacturing the filler component 6 using the above three wires will be described with reference to FIGS.
FIG. 5 is a plan view schematically showing an apparatus used in this manufacturing method. In the gear unit 27 shown in FIG. 5, the same number of spur gears 23 as the number of the packing body components 6 to be manufactured simultaneously as regular packing bodies are disposed between a pair of parallel racks 20 and 21. . Of the spur gears 23, the spur gears adjacent to the racks 20, 21 mesh with the teeth of the racks 20, 21, and the spur gears 23 disposed between the spur gears 23 that mesh with the racks 20, 21 are adjacent to each other. Engage with gears. Therefore, when the rack 20 is moved in the direction of arrow A and the rack 21 is moved in the direction of arrow B, the spur gear 23a at the top of the figure k as viewed in the direction orthogonal to the racks 20 and 21 rotates counterclockwise, and the next stage The spur gear 23b rotates in the clockwise direction, the spur gear 23c in the next stage rotates in the counterclockwise direction, and the other spur gear 23 similarly rotates in the clockwise and counterclockwise directions opposite to the adjacent spur gear 23. Rotate to either.

  In each spur gear 23, as shown in FIGS. 6A, 7, and 8, three through holes 24 having a central axis parallel to the rotation axis of each spur gear 23 are formed in each spur gear 23. (The central through-hole penetrates the central part of the spur gear mandrel 30 as shown in FIG. 8), and each of the through-holes 24 has three wires 6a to form each filler component 6 , 6b, 6c are inserted vertically. 6 and 7, the through holes 24 are shown in only some of the spur gears 23 for convenience of illustration, but the through holes 24 are formed in all of the spur gears 23.

  In FIG. 6B, a skewer reciprocating device 26, to which a plurality of ring forming skewers 25 are fixed, is provided on one side of the gear device 27 so as to be reciprocally movable in the direction of arrow CD. The skewers 25 are provided in the same number as that inserted between the three wires inserted into the through holes 24 of all the spur gears 23, but only four skewers are shown for the sake of simplicity. Has been. 6 and 7, the racks 20 and 21 of the gear unit 27 are not shown.

  In order to manufacture the packing body component 6 using the gear device 27, first, the three wires 6a, 6b, and 6c inserted through the three through holes 24 of the spur gears 23 are at the lowest in the vertical direction. Each spur gear 23 is rotated a predetermined number of times (at least one and a half revolutions) at a portion where the concentrating portion 17 is to be formed, and the concentrating portion 17 is twisted by twisting the three wires 6a, 6b and 6c below the spur gear 23. Form.

  Next, the three wires are moved downward by a predetermined dimension, and the skewer reciprocating device 26 is moved in the direction of arrow C in FIG. 6 at the portion where the ring-shaped portion 15 is to be formed in the three wires. As shown in FIG. 8, a ring-forming skewer 25 is inserted below the spur gear 23 so as to be positioned between the three wires 6a, 6b, 6c. The concentrated portion 17 is formed by twisting three wires below the spur gear 23 and above the skewer 25 by rotating a number of times.

  Next, the skewer reciprocating device 26 is retracted in the direction of arrow D and pulled out from the three wires to form the ring-shaped portion 15, and then the three wires are moved downward by a predetermined dimension. By repeating the rotation of 23, the pulling out of the skewer 25, and the downward movement of the wire, the ring-shaped portions 15 and the collecting portions 17 are alternately and repeatedly formed as many times as necessary, thereby producing a large number of filler components 6 simultaneously. be able to.

  According to the manufacturing method described above, the concentrating portion 17 is formed by twisting three wires, but the filler component may be manufactured not only by the above method but also by other methods. In addition to the method of twisting the wire, the concentrating portion may be assembled and fixed by other methods such as welding and clamping.

Next, a method for manufacturing the filling body component 6 using the two wires will be described with reference to FIGS.
9 and 10 are plan views schematically showing an apparatus used in this manufacturing method. 9 and 10, the same components as those in FIGS. 5 to 8 are denoted by the same reference numerals, and the description thereof is omitted.

  In this method, in order to form a ring, the skewer reciprocating device 26 is moved so that one skewer 25 is inserted between two wires and pulled out. Other operations are the same as the manufacturing method of a three-strand wire except for the manufacturing method.

Examples of the present invention will be described below.
The amount of gas-liquid contact treatment in the tower where the gas-liquid contact mechanism is installed is proportional to the speed in the tower (F factor, n / sec). For example, if the cross-sectional area of the tower is 2m ^2, and processing amount F Fuakuta is 2m / sec becomes 4m 3 ^/ sec, the processing amount F Fuakuta is 5 m / sec becomes 10 m 3 ^/ sec. The performance of the gas-liquid contact mechanism is expressed by the number of theoretical plates per unit height (NTS / m).

  As one embodiment of the present invention, a regular packing body of the embodiment shown in FIG. 2 is prepared as a single packing body component using three wires composed of six steel wires having a diameter of 0.4 mm. The inner diameter of each ring-shaped portion 15 was 3 mm, and the pitch between the two ring-shaped portions was 16.5 mm. As a comparative example, a regular filler was prepared by using a filler component made of the same wire and not forming a ring. The performance of the examples and comparative examples is shown in Table 1 below.

  From the above results, it can be seen that the performance of the gas-liquid contact device is significantly superior to the packing element having the ring compared to the packing element having no link.

  In addition, as a result of experiments, it has been found that the performance of the same-height filling member provided with a plurality of rings is better than that having a larger number of rings.
