Description

Apparatus for separating fluid

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid separation apparatus, and more particularly, to a fluid separation apparatus for separating a specific fluid in a mixed fluid in which a plurality of fluids are mixed.

Global warming, which is currently the subject of global interest, plays a major role in the greenhouse effect by carbon dioxide and methane gas. This warming not only disturbs the ecosystem but also has a great influence on the social life of the human being, so efforts to reduce the release of greenhouse gases into the atmosphere have been made in various ways.

Carbon dioxide has recently become one of the most noteworthy greenhouse gases. Carbon dioxide can be produced in sewage treatment plants, wastewater treatment plants, landfills, and the like in a large amount in a thermal power plant or a steel mill, in addition to being generated at the time of waste combustion. Therefore, a technique for separating and removing only carbon dioxide from waste gas is being studied. In addition to carbon dioxide, the interest in hydrogen fuel has been amplified, and the technology of separating hydrogen gas has also attracted much attention. In addition, since purely separated oxygen and nitrogen can be utilized in various fields, research on the separation method is continuing. In the future, as technologies for the utilization of specific gases or liquids develop, it is expected that separation techniques for a wider range of fluids will be required.

Separation of specific fluids is difficult to apply in industry simply by establishing separation theory. For example, the carbon dioxide separation technology has been proposed for a long time, such as absorption method, adsorption method, seawater cooling method, or membrane separation method. However, for practical reasons such as the necessity of enormous energy, side effects, It is very minimal.

However, since the membrane separation method uses relatively low energy compared to other methods, there is an evaluation that it is suitable for commercialization. The direction that has been studied so far in the membrane separation method is mainly to improve the separation efficiency of the membrane. The primary goal is to develop a small size (e.g., 1 inch X 1 inch) separator that can exhibit a separation efficiency of greater than 90% in the laboratory. Large-scale and commercialization are considered as next tasks.

In order to achieve a separation efficiency of more than 90% in the laboratory, many researchers have attempted to make the membrane thinner and to set the pressure difference between the inside and outside of the membrane higher. However, the thinner the thickness and the higher the pressure, the weaker the durability of the separator. Therefore, some researchers are also studying the materials of durable membranes even under these conditions.

However, even if a high-efficiency membrane is developed at the laboratory level as described above, commercialization thereof is a separate problem. First, it is very difficult to produce a thin film membrane in large quantities, and since expensive raw materials must be used, the production cost is greatly increased. Further, in order to apply a thin film membrane to a large-sized equipment, a large number of separators must be assembled, thereby increasing assembly time and assembly cost. Also, the use of high pressure for high efficiency increases the processing cost. Although it is theoretically possible to separate it, if production and processing costs are excessive, realistic commercialization is impossible.

 Therefore, it is necessary to develop a fluid separation technology applicable to a commercial scale, which has a low processing cost and a cost-effective separation efficiency.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fluid separation apparatus with improved separation efficiency.

The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings for explaining a fluid separator according to embodiments of the present invention.

1 is a view schematically showing a fluid separation apparatus according to a first embodiment of the present invention.

1, a fluid separation apparatus 1 according to an embodiment of the present invention includes a chamber 10 having a mixed fluid inlet 11, remaining fluid outlets 12a and 12b, and a separated fluid outlet 13, .

The mixed fluid inlet 11 forms a part of the first flow path F1 through which the mixed fluid flowing into the chamber 10 advances.

The fluid can be a gas or a liquid. The mixed fluid includes a plurality of different fluids. For example, the mixed fluid may be a thermal power plant or a plant exhaust gas, an automobile exhaust gas, a by-product gas, a waste landfill gas, a waste water, or the like.

The plural kinds of gases may be mixed completely uniformly, but not limited thereto. For example, only a first fluid may be present in a specific region and only a second fluid may be present in another specific region within a space containing a mixed fluid containing the first fluid and the second fluid. Also, the content of the first fluid at a particular site may be greater than the content of the first fluid at another particular site.

Separating a particular fluid from the mixed fluid involves not only completely separating the particular fluid from the mixed fluid, but also outputting (creating) a fluid mixture of increased specific fluid content from the input (provided) mixed fluid.

In the case where the input fluid mixture contains nitrogen and carbon dioxide and the content ratio thereof is 3: 1, the output fluid mixture is 100% carbon dioxide, or the output fluid mixture has a nitrogen to carbon dioxide content ratio of 3: 1 In the small case, it is interpreted that the carbon dioxide was separated.

If the output fluid is 100% nitrogen or the nitrogen and carbon dioxide content ratio of the output fluid mixture is greater than 3: 1, it is interpreted that the nitrogen is separated.

In addition, the higher the specific fluid content is, the higher the efficiency of the specific fluid separation.

Examples of the fluid to be separated may be other than the above-mentioned carbon dioxide or nitrogen. (N-C4H10), carbon disulfide (CS2), carbon monoxide, ethane, ethylene, helium, hexane (n-C6H14), hydrogen, hydrogen sulphide, methane, methanol, nitrogen monoxide , Nitrogen dioxide, nitrous oxide (N 2 O), octane, oxygen, pentane, propane, sulfur dioxide, toluene, water vapor, and the like.

Hereinafter, for convenience of explanation, a fluid separator according to an embodiment of the present invention will be described focusing on an example in which carbon dioxide is separated from a mixed gas composed of a plurality of kinds of gases including carbon dioxide. Accordingly, the 'gas' and the 'fluid' can be used in combination, and the 'fluid to be separated' and the 'carbon dioxide' can be used in combination. However, this is only for the specific description of the fluid separation apparatus according to the present embodiment, The present invention is not limited to the apparatus for separating carbon dioxide from the mixed gas.

The first flow path F1 may be connected to a tank (not shown) in which the mixed gas is stored and a pump (not shown) to allow the mixed gas to flow toward the mixed fluid inlet 11.

The chamber 10 is provided with a fluid separation unit 100 (see FIG. 2) for separating carbon dioxide from the mixed gas introduced into the chamber 10 through the mixed fluid inlet 11. The fluid separation unit (100) separates at least a portion of the carbon dioxide contained in the mixed gas in the chamber (10) from the mixed gas. In the gas separated from the mixed gas by the fluid separation unit 100, gas other than carbon dioxide may be partially included.

The separation gas separated from the mixed gas by the fluid separation unit 100 is discharged to the outside of the chamber 10 through the separation fluid outlet 13 forming part of the second flow path F3.

The remaining fluid outlets 12a and 12b form a third flow path F2 through which the residual gas inside the chamber 10 advances to the outside of the chamber 10. [ The residual gas means a gas which has not been separated by the fluid separation unit 100 from the mixed gas introduced into the chamber 10. The third flow path F2 may be connected to a tank (not shown) for collecting residual gas discharged to the outside of the chamber 10.

The fluid separating apparatus 1 according to the present embodiment can be used in a plurality of chambers 10 stacked and used so that the mixed fluid inlets 11, the remaining fluid outlets 12a and 12b, The fluid outlet 13 is preferably formed on the side surface, the front surface, or the rear surface of the chamber 10.

1, the remaining fluid outlets 12a and 12b may be formed on the front surface and the rear surface of the chamber 10, respectively. Depending on the installation environment of the chamber 10, the remaining fluid outlets 12a and 12b formed on the front surface and the rear surface of the chamber 10 may be all used or only one of them may be used. For example, when it is difficult to provide a pipe for forming the third flow path F2 to the rear surface of the chamber 10 due to the characteristics of the installation place of the chamber 10, So that the residual gas can be discharged through only the gas supply pipe 12a.

Although not shown, mixed fluid inlets 11 and / or separate fluid outlets 13 may likewise be formed on the front and back sides of the chamber 10, respectively.

1, the second flow path F3 may be connected to the pump 20 and the tank 30. As shown in FIG.

The pump 20 maintains a space communicating with the second flow path F3 and the second flow path F3 in a negative pressure atmosphere. The negative pressure atmosphere formed by the pump 20 causes the separated gas separated by the fluid separation unit 100 to be discharged out of the chamber 10 more smoothly. Further, the negative pressure atmosphere formed by the pump 20 promotes a series of processes in which carbon dioxide is separated from the mixed gas by forming a pressure difference between the mixed gas and the separated gas.

The separated gas discharged to the outside of the chamber 10 through the second flow path F3 is collected in the tank 30.

2 is a schematic view showing the internal structure of a fluid separation apparatus according to a first embodiment of the present invention.

2, a chamber 10 of the fluid separation apparatus 1 according to the first embodiment of the present invention is connected to the mixed fluid inlet 11 to form a part of the first flow path F1 And a plurality of fluid separation units (100) for separating carbon dioxide from the mixed gas introduced into the chamber (10) through the mixed fluid diffusion unit (200) And a residual fluid collecting part 300 connected to the fluid outlet 12 to form a part of the third flow path F3.

2 shows a fluid separation unit composed of four fluid separation units 100 for convenience of explanation. However, the fluid separation unit 100 is arranged in the chamber 10 according to the size of the chamber 10 and / or the size of the fluid separation unit 100 The number of the fluid separation units 100 may vary.

The space in the chamber 10 is divided into a first space connected to the second flow path F3 and a second space connected to the first flow path F1 and the third flow path F2.

The first space is composed of the inner space of the fluid separation units 100 and the second flow path F3 and the second space is the space in the chamber communicating with the mixed fluid diffusion part 200 and the remaining fluid collection part 300 .

Since the second flow path F3 is connected to the pump 20 (see FIG. 1) and receives the negative pressure from the pump 20, a negative pressure atmosphere is formed in the first space connected to the second flow path F3. In the inner space of the separation tube 110 forming a part of the first space, a negative pressure atmosphere of about 0 to 1 kgf / cm 2 compared to the atmospheric pressure can be formed.

The second space in the chamber 10 connected to the first flow path F1 and the third flow path F2 may be formed with a positive pressure atmosphere different from the first space. A compression pump (not shown) for compressing and supplying a mixed gas may be connected to the first flow path F1 to which the mixed gas is supplied to form a positive pressure atmosphere in the first space. The first space has a pressure of 0 to 4 kgf / cm < 2 > A high positive pressure atmosphere can be formed.

The mixing fluid inlet 11 and the mixed fluid diffusing portion 200 are formed in the lower portion of the chamber 10 and the remaining fluid outlets 11 and 12 are formed in the chamber 10 as shown in FIG. 12 and the remaining fluid collecting part 300 are formed on the upper part of the chamber 10.

The mixing fluid inlet 11 and the mixed fluid diffusing portion 200 are formed on the upper portion of the chamber 10 and the remaining fluid outlet 12 and the remaining fluid collecting portion 20 are formed in the upper portion of the chamber 10, (300) is formed in the lower part of the chamber (10).

On the other hand, as shown in FIG. 2, the bottom surface of the chamber 10 may be convex downward toward the center. At the center of the bottom surface, a condensate outlet 16 communicates with the inside of the chamber 10 and is formed toward the lower portion of the chamber 10.

The condensed water discharge port 16 forms a path for discharging the mixed gas in the chamber 10 and / or the condensed water generated as the residual gas is cooled out of the chamber 10.

Hereinafter, the fluid separation unit 100, the mixed fluid diffusion unit 200, and the residual fluid collection unit 300 will be described in detail.

3 is a perspective view showing a fluid separation unit according to the first embodiment of the present invention.

3, the fluid separation unit 100 according to the first embodiment of the present invention includes a plurality of separation tubes 110, a separation tube holding portion 140 for supporting the plurality of separation tubes 110, And a first separating fluid collecting unit 160 receiving the separated gas separated from the mixed gas by the plurality of separating tubes.

As shown in FIG. 3, the plurality of separation tubes 110 in the fluid separation unit 100 may be arranged in two rows. The separation tube holding parts 140 and 150 include a hanger holder 240 provided for each row in which the separation tubes 110 are arranged and a plurality of separation tube hangers 250 supported by the hanger holder 240. [

As shown in FIG. 3, each separation tube hanger 250 supports the center of the separation tube 110 to maintain the separation tube 110 in a U-shaped bend state.

The separation tube 110 is a tubular member that forms a space in the interior thereof. The separation tube 110 may be manufactured in such a manner that edges of two sheets are joined together or extruded into a tube having an inner diameter and an outer diameter.

When a polymer material such as a silicone rubber is manufactured into a tubular shape by an extrusion method, it is required to have a thickness of about 0.1 mm or more so that it can be easily manufactured. If it has a thickness of 0.4 mm or more, commercial mass production can also be done. On the other hand, as the thickness of the pipe wall of the separation tube 110 is thicker, the movement distance of the separation target fluid (carbon dioxide) becomes longer, thereby deteriorating the separation efficiency of the fluid.

However, if the thickness of the tube wall of the separation tube 110 exceeds 2 mm, fluid mobility of the separation target fluid (carbon dioxide) in the fluid separation apparatus using low energy is drastically reduced, And the fluid separation efficiency is lowered.

Therefore, it is preferable that the thickness of the separation tube 110 is selected within the range of 0.1 mm to 2 mm, or 0.4 mm to 2 mm.

Also, considering the commercial mass production, the inner diameter or outer diameter of the separation tube 110 may be made between about 60 mm and 300 mm.

If the length of the separation tube 110 is too short, the number of times of installation increases, which is disadvantageous to handling. Therefore, the length of the separation tube 110 is preferably 500 mm or more. If the length of the separation tube 110 is too long, it is difficult to discharge the separation target fluid (carbon dioxide) which has entered the separation tube 110 only by using low energy, and the concentration of the specific fluid inside the separation tube 110 can be uniformly controlled It is difficult to do. Therefore, the length of the separation tube 110 is preferably 5000 mm or less.

At both ends of the separation tube 110, an adapter tube 110 having an inner diameter and an outer diameter smaller than the inner diameter of the separation tube 110 is used for easier connection of both ends of the separation tube 110 to the first separation fluid aggregate portion 160. [ (120, 130), respectively.

The separation tube 110 is in contact with the mixed gas in the chamber 10 and selectively passes the carbon dioxide contained in the mixed gas into the inner space of the separation tube 110 to separate the carbon dioxide from the mixed gas.

This is due to the nature of the silicon which is the main component of the separation tube 110 and is based on the carbon dioxide selectivity of the silicon. In addition, the selectivity of carbon dioxide is improved in the case of the separation tube 110 produced by mixing or coating ceramics with silicon.

Since the first space (outside the separation tube 110) in the chamber 10 in which the mixed gas exists is formed in a positive pressure atmosphere and the inner space of the separation tube 110 is formed in a negative pressure atmosphere, The carbon dioxide can be smoothly permeated to the inside of the separation tube 110 from the mixed gas by the pressure difference between the inside and the outside of the separation tube 110. [

As shown in FIG. 3, the separation tube 110, which is bent so as to have a U-shape as a whole, has a larger contact area with the mixed gas than when the separation tube having the same inner diameter and outer diameter is provided in a straight line . Therefore, the carbon dioxide separation efficiency is improved.

Also. It is better to install two separate tubes. As shown in FIG. 3, since it is simpler to bend the single separation tube 110 once, it is possible to simplify the work of installing the separation tube 110 in the chamber 10.

In addition, when the separation tube is installed in a straight line, since both ends of the separation tube exist in the upper part and the lower part of the inside of the chamber 10, the connection structure between both ends of the separation tube and the second flow path F3 becomes complicated, The both ends of the separation tube 110 are located at the lower portion of the chamber 10 so that the both ends of the separation tube 110 and the second flow path F3 Can be relatively simple.

4 is a front view showing a coupling relation between the separation tube hanger and the hanger holder in Fig.

3 and 4, the separation tube hanger 150 includes a support 151 for supporting one point of the separation tube 110 and a pair of hooks 152 extending upward from both ends of the support 151, Portions 152a and 152b. The pair of hooks 152a and 152b may extend in a direction approaching each other so that the detachable tube hanger 150 has a C-shape as a whole.

3 and 4, the hanger holder 140 has a bar shape elongated in one direction, and hooks 152a and 152b of the separation tube hanger 150 are formed on both sides of the hanger holder 140, Receiving portions 141 and 142 to which the end portions of the receiving portions 141 and 142 are supported are recessed inward. The receiving portions 141 and 142 are also elongated along one direction.

The separation tube hanger 150 supports the separation tubes 110 to bend in a U-shape so that the ends of the hanger parts 152a and 152b are respectively positioned at the front ends of the receiving parts 141 and 142 of the hanger holder 140 The hanger holder 140 is inserted into the hanger holder 140 in such a manner that the hanger holder 140 slides along the receiving portions 141 and 142 toward the rear end of the hanger holder 140, Are placed in line in the hanger holder 140. [ At this time, the separation tubes 110 can be arranged such that the distance between the separation tubes 110 is equal to or less than the thickness of the separation tubes 110, or less than the diameter or width of the separation tubes 110. For example, the interval of the separation tubes 110 may be set within a range of 0.1 mm to 500 mm. When the interval of the separation tubes 110 is less than 0.1 mm, the separation tubes 110 can be brought into close contact with each other and the effective surface area of the separation tubes 110 can be reduced. If the distance between the separation tubes 110 exceeds 500 mm, the number of the separation tubes 110 installed in the chamber 10 is reduced more than necessary to reduce the efficiency of fluid separation.

FIG. 5 is a cross-sectional view of the separation tube of FIG. 3. FIG.

As shown in Fig. 5, the separation tube 110 can be closed at a point supported by the support portion 151 in the bending region B1. Since the separation tube 110 is made of silicon as a main component and has excellent ductility, a point supported by the support portion 151 due to the self weight of the separation tube 110 can be closed.

As a part of the inside of the separation tube 110 is closed, the inside of the separation tube 110 is divided into two spaces 111 and 112. Separated gas containing carbon dioxide, which has passed through the separation tubes 110 to the respective spaces 111 and 112, is moved from the occluded point to both ends of the separation tube 110.

The central portion of the separation tube 110 is closed so that the inside of the separation tube 110 is separated into two spaces 111 and 112 and the separated gas is discharged from the two spaces 111 and 112, The discharge efficiency of the exhaust gas is increased.

The separated gas moved to both ends of the separation tube 110 passes through the adhesion tubes 120 and 130 and is transferred to the first separation fluid aggregate part 160.
