Description

[0001] Gas-liquid device [0002]

The present invention relates to a gas-liquid apparatus.

Generally, a reaction device is required to obtain a product through a chemical reaction. As such a reaction apparatus, a batch type reactor in which a raw material product is added to one reactor and stirring is performed, has been used. However, in the case of using a batch reactor, sufficient reaction can not be performed for a reaction requiring a fast mass transfer rate, and a large amount of raw material product can be generated. In the case of using a catalyst, a separation process of the catalyst is essential. There is a problem of rising.

To solve this problem, a spinning disk reactor has been proposed. However, since the spinning disk is arranged horizontally, there is a problem that the retention time of the raw material reactant in the disk is short. Therefore, a cone-shaped spinning cone column (SCC) has been proposed which improves the retention time of the raw material reactant by providing a disk having a slope, that is, a cone.

In such a spinning cone column, a fin is formed in the rotating cone, as disclosed in the patent documents of the following prior art documents. Here, the fin increases the rising flow rate of the introduced gas to promote the separation of volatile components contained in the reactant, and increases the residence time of the reactant to increase the removal efficiency of volatile components. However, the spinning cone column according to the prior art increases the rotational speed of the rotating cone, increasing the rising velocity of the gas, thereby reducing the residence time of the reactant. Conversely, if the rotational speed of the rotating cone is reduced to reduce the residence time of the reactant, the rising flow rate of the gas is reduced. That is, as the rotational speed of the rotating cone changes, the rising velocity of the gas and the residence time of the reactant change inversely with each other. Therefore, there is a limitation in increasing the removal efficiency of volatile components through the change of the rotating speed of the rotating cone.

1 and 2, the gas-liquid storage device 100 according to the present embodiment includes a housing 110, a rotating shaft 120 provided inside the housing 110, The rotary cone 130 rotates about the rotary shaft 120. The rotary cone 130 extends downward from the upper end of the outer circumferential surface of the rotary cone 130. The lower end of the rotary cone 130 has a width and a fixed cone 150 fixed to the housing 110 so as to be spaced apart from the rotary cone 130 and formed in a tubular shape whose diameter decreases from the upper end to the lower end.

The housing 110 is generally formed in a tubular shape having a space for accommodating the rotary shaft 120, the rotary cone 130, the pin 140, and the fixed cone 150 therein. Here, the material of the housing 110 may be, for example, stainless steel, but is not limited thereto. The housing 110 may be provided with a first supply part 113 for supplying a reactant and a second supply part 115 for supplying a gas to the housing 110. Here, since the reactant moves downward due to gravity, the first feeder 113 for supplying the reactant may be provided at the upper end of the housing 110. At this time, the first supply part 113 may be provided with two or more reactors so as to supply two or more reactants. In addition, since the gas reacts with the reactant while moving toward the upper side opposite to the reactant, the second feeder 115 for supplying the gas may be provided at the lower end of the housing 110. The housing 110 may be provided with a discharge portion 117 for discharging the residual gas from the housing 110 and a collecting portion 119 for collecting the product from the housing 110. Here, since the residual gas is the gas after reacting with the reactant while moving to the upper side, the discharge unit 117 for discharging the residual gas may be provided at the upper end of the housing 110. Since the product is generated by reacting with the gas or by gas treatment while moving the reactant downward, the collecting unit 119 for collecting the product may be provided at the lower end of the housing 110. That is, the first supply part 113 and the discharge part 117 may be provided at the upper end of the housing 110, and the second supply part 115 and the collecting part 119 may be provided at the lower end of the housing 110 It is. However, the positions of the first supply portion 113, the second supply portion 115, the discharge portion 117, and the collecting portion 119 are illustrative and are not necessarily limited to the above-described positions. For example, in FIG. 1A, the first supply part 113 is formed on the side surface of the housing 110, and the discharge part 117 is formed on the upper surface of the housing 110. However, The first supply part 113 may be formed on the upper surface of the housing 110 and the discharge part 117 may be formed on the side surface of the housing 110 as shown in FIG.

The rotary shaft 120 rotates the rotary cone 130 and is formed along the longitudinal direction (e.g., the vertical direction) of the housing 110 in the housing 110. Here, the rotating shaft 120 may be rotated by a driving unit 125 connected to one side.

The rotary cone 130 has a lower end mounted on the rotary shaft 120. Accordingly, when the rotating shaft 120 is rotated by the driving unit 125, the rotating cone 130 can rotate based on the rotating shaft 120. Also, the rotary cone 130 is formed in a tubular shape whose diameter decreases from the upper end to the lower end. That is, the rotary cone 130 can be formed as a whole in the shape of a "V" When the reactant is injected into the rotary cone 130, the reactant is spread by the centrifugal force along the rotary cone 130 in the form of a thin film, moved to the upper end, and then transferred to the stationary cone 150. On the other hand, the rotary cone 130 may further include an extension 135 extending radially from the top (see also the enlarged view of FIG. 1A). That is, the rotary cone 130 is formed as a whole with a "V" shape, and an extension 135 extending in the outward direction may be formed at the upper end.

The fin 140 is installed on the upper portion of the rotary cone 130 to increase the rising velocity of the gas to promote the separation of the volatile components contained in the reactant and to increase the residence time of the reactant, . Specifically, the fin 140 rotates together with the rotating cone 130 to generate an air flow, which influences the rising velocity of the gas and the residence time of the reactant. Here, the pin 140 extends downward from the upper end of the outer circumference of the rotary cone 130, and the width w increases from the upper end to the lower end. For example, as shown in FIG. 3A, the ratio of the width w of the fin 140 increasing from the upper end to the lower end may correspond to the rate at which the diameter of the rotary cone 130 decreases from the upper end to the lower end have. The rim 145 of the pin 140 farthest in the radial direction from the rotating shaft 120 can extend along the inner circumferential surface 110a of the housing 110 (or perpendicular to the paper surface). It is to be understood that the rim 145 of the pin 140 and the inner circumferential surface 110a of the housing 110 are parallel to each other or that the rim 145 of the pin 140 and the paper surface are perpendicularly mathematically completely parallel or perpendicular But is meant to include a slight change in angle due to a manufacturing error occurring in the manufacturing process. 3B to 3C, the rim 145 of the fins 140 farthest from the rotation axis 120 in the radial direction is formed in the inner peripheral surface 110a of the housing 110, 5 to + 5 [deg.] (See [alpha], [beta]).

In addition, although the overall shape of the fin 140 is not particularly limited, it may be a triangular shape, and more specifically, it may be a right triangular shape as shown in FIG. 3D. At this time, the hypotenuse 147 of the right triangular shape may contact the outer circumferential surface of the rotary cone 130. The rim 145 of the pin 140 farthest from the rotation axis 120 in the radial direction may extend to the lowermost end of the pin 140. [

On the other hand, the fin 140 is not formed entirely along the outer circumferential surface of the rotary cone 130 but is formed only on the upper portion of the rotary cone 130, so that a strong airflow can be generated intensively. The pin 140 is formed only at a predetermined length or less of the entire length (L, see Fig. 3d) of the inclined outer circumferential surface of the rotary cone 130 so that the fin 140 is formed only on the upper portion of the rotary cone 130 . Here, the predetermined ratio is not necessarily limited to, for example, 50% or less.

The pin 140 may be formed inside the extended portion 135 of the rotary cone 130 (see the enlarged view of FIG. 1A). That is, the pin 140 may be disposed closer to the rotation axis 120 than the extension 135 of the rotation cone 130. This is to prevent contact of the pin 140 when the reactant (liquid) is transferred from the rotary cone 130 to the fixed cone 150.

The fixed cone 150 is fixed to the inside of the housing 110 and is formed in a tubular shape whose diameter decreases from the upper end to the lower end. That is, the fixed cone 150 can be formed as a whole in the shape of a "V" The fixed cone 150 is spaced apart from the rotary cone 130 and is formed so as to surround the outer side of the rotary cone 130 so that the fixed cone 150 can receive the reactant from the rotary cone 130 . In addition, the stationary cone 150 and the rotary cone 130 may be alternately provided in the housing 110.

4 to 5 are sectional views showing the operation of the gas-liquid supply device according to the embodiment of the present invention, and the operation of the gas-liquid supply device 100 will be described with reference to FIG.

4, the driving unit 125 is operated to rotate the rotary cone 130, and the reactant is supplied to the housing 110 through the first supplying unit 113 (A) (B) through the housing 115 to the housing 110. In this case, the reactant may be selected from the group consisting of PVC, SBR, NBR, ABS, and PBL latex, although it is not particularly limited as long as it is a polymer containing a volatile monomer. In addition, the gas may be hot steam that can supply heat to the reactants.

5, the reactant supplied to the housing 110 is transferred to the rotary cone 130, and then moved to the upper end of the rotary cone 130 by centrifugal force. Thereafter, it is separated from the rotary cone 130 and transferred to the fixed cone 150. The reactant transferred to the stationary cone 150 moves to the lower end of the stationary cone 150 along the slope of the stationary cone 150 and is then transferred from the stationary cone 150 to the rotary cone 130 again. On the other hand, the gas supplied to the housing 110 reacts with the reactant while moving upward. At this time, since the reactant is thinly spread by the centrifugal force of the rotary cone 130, the gas and the reactant can react in a wide area. Thus, when the reactant reacts with the gas, the volatile organic compound is removed from the reactant, and the residual gas containing the volatile organic compound and the gas is discharged to the discharge portion 117 (C). Further, the reactants (products) from which the volatile organic compounds have been removed are collected in the collecting unit 119 (D).

Meanwhile, during the operation described above, the fin 140 rotates together with the rotary cone 130 to increase the rising velocity of the gas to promote separation of the volatile components contained in the reactant, increase the residence time of the reactant, Min. ≪ / RTI > Additionally, the pressure inside the housing 110 can be reduced or increased to effectively effect reaction of the reactants with the gas.

FIG. 6A is a gas-liquid apparatus according to an embodiment of the present invention, and FIG. 6B is a sectional view of a gas-liquid apparatus according to a comparative example.

The fin 140 of the gas-liquid apparatus 100 according to the embodiment of the present invention shown in FIG. 6A is formed in a triangular shape as a whole and formed on the upper portion of the rotary cone 130. On the other hand, the pin 240 of the gas-liquid apparatus 200 according to the comparative example shown in FIG. 6B is formed in a rectangular shape as a whole, and is formed along the outer circumferential surface of the rotary cone 230, . However, the pin 140 according to the embodiment of the present invention and the pin 240 according to the comparative example have the same sectional area. That is, the fin 140 according to the embodiment of the present invention is formed on the upper portion of the rotary cone 130 after reducing the ratio of the length / width while maintaining the sectional area of the fin 240 according to the comparative example. Accordingly, the pin 140 according to the embodiment of the present invention intensively generates strong airflow only at the upper portion of the rotary cone 130, while the pin 240 according to the comparative example is tangent to the entire circumferential surface of the rotary cone 230 To generate airflow in the direction of the arrow. Because of this difference, the pin 140 according to the embodiment of the present invention can have a P / V (output on the fluid (gas and reactant)) / (volume of the fluid) at the same rotational speed as the pin 240 according to the comparative example )], Thereby increasing the force on the fluid (gas and reactant).

In order to prove this, numerical values measured through actual experiments are shown in Table 1 below.

Rotation speed

(W / m ³ ) Fluid
Maximum speed Fluid

The gas- 75 4.74 8.10 1.71 0.05 -0.250 0.297
The gas-liquid separator according to the embodiment of the present invention 75 4.90 8.88 1.72 0.07 -0.253 0.282

When the gas-liquid apparatus 100 according to the embodiment of the present invention and the gas-liquid apparatus 200 according to the comparative example are rotated at the same rotation speed of 75 rpm, the gas-liquid apparatus 100 according to the embodiment of the present invention, (4.74 W / m < ³ > - 4.90 W / m < ³ >). In addition, the gas-liquid apparatus 100 according to the embodiment of the present invention has an increased upward flow (-0.250 m / s to -0.253 m / s) as compared with the gas-liquid flow apparatus 200 according to the comparative example, (0.297 m / s to 0.282 m / s). As described above, if the upward flow is increased, the upward flow rate of the gas can be increased. Further, if the downward current is decreased, the residence time of the reactant (liquid) in the rotating cone 130 can be increased. This can be confirmed by the fact that the amount of the reactant is increased (0.05 m < ³ > - 0.07 m < ³ >) in the gas-liquid apparatus 100 according to the embodiment of the present invention as compared with the gas-

As a result, the gas-liquid apparatus 100 according to the embodiment of the present invention can simultaneously increase the rising velocity of the gas and the residence time of the reactant, compared with the gas-liquid apparatus 200 according to the comparative example, It can be confirmed that the removal efficiency of the volatile components contained in the reactant can be increased.

As described above, the gas-liquid apparatus 100 according to the present invention may be a gas-liquid reactor in which reactants react with a gas to remove volatile organic compounds from the reactants. However, reactants and gases do not necessarily have to undergo a chemical reaction. For example, the gas-liquid apparatus 100 according to the present invention can be used to separate materials through gas contact. Specifically, the liquid mixture can be used to separate materials (e.g., volatile substances, etc.) contained in the mixture by contacting the mixture with a gas (especially a hot gas). However, the mixture is not limited to a two-phase component mixture in which a gaseous substance is dissolved in a liquid substance, and may be a three-phase component mixture further containing a solid phase material. That is, the gas-liquid apparatus 100 according to the present invention can be used not only for separation of two-phase component materials but also for separation of three-phase component materials.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
