Description

[0001] SEPERATOR FOR COG PIPE LINE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separator for COG transfer piping, and more particularly, to a separator for COG transfer piping, which is installed in a supply pipe to which coke oven gas generated during the course of producing coke by carburizing coal in a coke oven, And separating and removing impurities from the coke oven gas using centrifugal force.

Unless otherwise indicated herein, the contents set forth in this section are not prior art to the claims of this application and are not to be construed as prior art to be included in this section.

Generally, a coke oven gas (hereinafter, referred to as COG) is generated in the process of producing coke by the carbonization process using coal. This COG is recovered as a by-product and transported through the coke oven gas transfer piping to be used as a heat source in the unit process of the steelworks.

At this time, COG contains a large amount of contaminants (hereinafter referred to as 'impurities') such as tar, water, naphthalene, hydrogen sulfide, ammonia and benzene, toluene and xylene.

Since COG contains impurities, it is not suitable to be used immediately as a heat source because it has poor heat supply ability. In particular, it causes corrosion on the pipeline or acts as a cause of the clogging phenomenon and causes various problems in the piping.

As shown in FIG. 1, impurities are removed from the mixed gas by using the centrifugal force generated by the swirling flow of the fluid, as shown in FIG. 1, and various impurity separating devices for purifying COG are installed in the piping to which the COG is delivered. (Hereinafter referred to as a "cyclone separator") is one of them.

1 shows a structure of a separator using a conventional cyclone principle. The cyclone separator 1 shown in Fig. 1 has a main body 2 which is usually constituted by an upper cylindrical portion and a lower conical portion, , A gas discharge pipe (4) for partially discharging gas into the upper cylindrical portion to discharge the gas to the outside, and a gas inlet (4) communicating with the side surface of the upper cylindrical portion to circulate the mixed gas in which the impurities are mixed, And a pipe (5).

In the conventional cyclone separator, the mixed gas is introduced into the main body through the gas inlet pipe, and the introduced mixed gas is guided to the inner surface of the main body by the gas discharge pipe and is lowered while turning. Therefore, the residual impurities are pushed outwardly, that is, to the inner surface of the body by the centrifugal force while rotating, thereby separating the impurities from the gas. The gas separated from the impurities by the above-mentioned means is re-raised through the center of the swivel and discharged through the gas discharge pipe, and the separated impurities are descended along the inner surface of the main body and discharged through the discharge port.

Although the cyclone separator has a simple structure, the cyclone separator effectively separates the impurities from the mixed gas. However, there is a problem that the descending pivot shaft of the mixed gas partially overlaps the path of the impurities to decrease the turning force and increase the pressure loss. In addition, there is a need for a device capable of removing impurities more efficiently since the impurities which descend are re-raised and mixed with the purified gas to be discharged to the discharge port.

As a prior art related to an impurity separating apparatus for purifying COG in a piping to which COG is transferred, Korean Patent Registration No. 10-0384448 (May 2003, 2003) entitled "a process for producing an emulsion- And a prior art related to the cyclone separator is disclosed in Korean Patent Registration No. 10-1524469 (Feb. 26, 2015) entitled " Hydrogen separation device for COG gas ".

7, a separator 100 for a COG transfer pipe according to an embodiment of the present disclosure includes a coke oven (not shown) generated during the course of producing coke by coal- The apparatus 10 for purifying COG by removing impurities is connected to a supply pipe 12 through which COG flows and a secondary separator 14 for generating charges and droplets by high voltage so that impurities are separated from the COG, The separator 100 for primary separation includes a supply pipe 12, a housing 110, an impurity outlet 120, a vortex forming fan 130, a first steam nozzle 140, a steam guide 150, A first steam nozzle 160, and a second steam nozzle 170.

The supply pipe 12 communicates with a coke oven (not shown), and a heated coke oven gas (COKE OVEN GAS, COG) flows. Here, the supply pipe 12 is a normal transfer pipe interconnecting the respective processes for flowing COG, including a bypass pipe in the apparatus 10 for cleaning the COG as shown in FIG. 7, The same reference numerals are used.

2 to 5, the housing 110 includes an inlet 111 communicating with the supply pipe 12, an outlet 112 through which the COG is discharged, a steam reflector 113 formed adjacent to the outlet 112, .

As shown in FIG. 3, the housing 110 induces the COG to move while swirling through the vortex formed therein, thereby separating the impurities from the COG by the centrifugal force by the swirling force, and causing the COG to collide with the inner surface, .

As shown in FIGS. 4 and 5, the housing 110 has an inner circumferential surface that increases in volume toward the steam reflecting portion 113. That is, the housing 110 is provided with a substantially conical shape of a neck-sized rear bulb having a discharge opening 112 in front of the inlet 111 and a rear bulge having a larger diameter, and a rear portion provided with a discharge opening 112 is provided in a dome shape .

The housing 110 is provided in the shape of a cone back light having a hemispherical shape rear side as described above, so that COGs that are turned and moved along the inner surface of the housing 110 are prevented from overlapping the movement paths from the front to the rear and backward . In other words, when the COG moves from the front to the rear due to the change in the diameter of the housing 110, the housing 110 is swiveled close to the inside of the housing 110 and moved along the curved inner surface, . This makes it possible to provide a moving path for smoothly turning directions while maintaining the turning force as much as possible, thereby reducing the pressure loss due to the lowering of the turning force, thereby enabling efficient separation.

The inlet port 111 and the outlet port 112 are formed in a hollow rod shape and are connected to the front and rear sides of the housing 110 so that the center axes thereof are aligned with each other to be connected to the supply pipe 12 through flange- And the secondary separator 14, respectively. At this time, it is preferable that the discharge port 112 of the present disclosure has the front side end positioned inside the housing 110.

The steam reflection part 113 is positioned on the inner peripheral surface of the dome-shaped housing 110 having the discharge port 112. The steam reflecting portion 113 is formed to have a curved portion on the inner circumferential surface of the housing 110 through the shape of the dome-shaped housing 110. The steam injected through the second spraying nozzle 170, which will be described later, So that impurities existing on the rear side inside the housing 110 are adsorbed on the steam and fall down in the downward direction before and after the injection.

The impurity outlet 112 discharges impurities separated from the COG passing through the housing 110. The impurity outlet 112 is formed on the lower outer circumferential surface of the dome-shaped housing 110 toward the lower side in the tangential direction perpendicular to the outlet 112. The impurity outlet 112 is connected to the housing 110 and extends from the lower end corresponding to the largest diameter of the housing 110 to the lower end of the outlet 112, All are formed to communicate with each other. The end side located at the largest diameter of the housing 110 is formed in a gentle curved funnel shape whose diameter decreases from the top to the bottom. This makes it easy for the impurities adsorbed on the steam to flow down on the inner surface of the housing 110 and on the inner surface of the gentle curve of the impurity outlet 112, thereby enabling quick and smooth discharge.

6 is a perspective view of the vortex forming fan and the steam guide shown in Fig.

Referring to FIGS. 5 and 6, the vortex forming fan 130 is rotatably installed in the housing 110 adjacent to the inlet 111. The vortex forming fan 130 forms a vortex that causes the COG introduced into the inlet 111 to move toward the rear of the housing 110 in the direction of the outlet 112 while turning along the inner surface of the housing 110. 6, the vortex-forming fan 130 includes a plate 131 coupled to the inner surface of the housing 110 and an outer periphery thereof. The vortex-forming fan 130 is rotatably coupled to the front surface of the plate 131, And a rotating body 132 provided with a plurality of blades 1321 protruding and spaced apart from each other. A plurality of blades 1321 and a plurality of vanes 1321 are formed in the rotating body 132 so as to be alternated with a plurality of vanes 1321 formed at the edges of the vanes 1321 formed between the blades 1321, A cutout groove 1311 is formed along the corresponding edge of the cutout 1322. The plurality of vanes 1221 provided in the rotating body 122 are inclined at a predetermined angle in the circumferential direction of the rotating body 122 and are connected to the vortex forming fan 130 through the discharge pressure of the COG supplied from the supply pipe 12. [ So that a vortex that causes the COG to turn is formed. Here, the vortex forming fan 130 is a kind of sirocco fan structure that blows fluid by a plurality of vanes 1221, so that a vortex forming fan 120 having various structures and shapes can be used.

The first steam nozzle 140 is installed between the inlet 111 and the vortex forming fan 130 and injects steam supplied from the outside toward the vortex forming fan 130. The first steam nozzle 140 causes steam to be injected into the COG to be passed through the vortex forming fan 130 so that impurities are adsorbed on the front side of the inside of the housing 110 to be dropped downward.

The steam guide unit 150 is formed between the vortex forming fan 130 and the first steam nozzle 140 to guide the steam to the vortex forming fan 130 in a streamlined flow. The steam guiding part 150 is formed into a conical shape having a smaller cross section toward the inlet 111 and protrudes from the front surface of the plate 131. The COG introduced through the inlet port 111 and the steam injected from the first steam nozzle 140 are guided along the conical outer circumferential surface to thereby pass through the plurality of blades 1321 and the through holes 1322 and the incision grooves 1311 So that the COG is smoothly moved backward with a swinging force expanding toward the inner surface of the housing 110.

The collecting port 160 is formed in an umbrella shape inclined at a predetermined inclination toward the rear along the edge at the end of the discharge port 112 disposed inside the housing 110. When the steam injected through the second steam nozzle 170 is tinted back into the housing 110 by the steam reflection part 113, the trap 160 is not moved to the front of the discharge port 112, 113) for a long period of time. Further, the trap 160 is formed in an umbrella shape having an inclined surface, and the edge is adjacent to the inner circumference having the largest diameter of the housing 110, so that the COG moving space is narrowed so that the turning force of the COG is not lowered.

The second steam nozzle 170 is installed between the trap 160 and the steam reflection part 113 and injects steam to the COG which is to be refluxed. That is, the second steam nozzle 170 distributes the steam evenly throughout the housing 110 together with the first steam nozzle 140, thereby providing an environment in which the steam can be adsorbed to the steam at any position during the movement of the impurities do. The second steam nozzle 170 is positioned adjacent to the trap 160 to spray steam toward the steam reflection part 113. This allows steam to be most efficiently sprayed to the curved portion of the steam reflecting portion 113, thereby sufficiently securing a space between the steam reflecting portion 113 and the catching hole 160, so that the time during which the impurities come into contact with the steam is increased, Thereby increasing the treatment efficiency.

The separator 100 for a COG transfer pipe of the present disclosure having the above-described configuration is constructed so that the COG introduced into the inlet port 1 and the first and second steam nozzles 140 and 140, So that the impurities can be continuously discharged through the discharge port 112. That is, the housing 110 is pressurized by the COG and the steam injected at the set temperature and pressure, thereby increasing the pressure inside the housing 110. Accordingly, when the internal pressure of the housing 110 reaches or exceeds the permissible set pressure, The COG purified by the car is discharged to the outside of the housing 110 through the discharge port 112. [ Therefore, the separator 10 for a COG transfer pipe of the present disclosure does not need a device such as a drive motor for rotating the vortex forming fan 130, or a pump or the like for feeding the purified COG to the discharge port 112 And performs the role of the impurity separation function continuously. Therefore, there is an advantage that it is easy to deform the size and the shape according to the target gas to be processed, and can be freely installed at the inlet and the outlet of the supply pipe 12 or at a specific place to be installed. The separator 100 for COG transfer piping of the present disclosure mainly removes particulate matter such as tar and moisture, and has a removal efficiency of 5 to 10 MICRONS particles of 80% or more.

In the separator 100 for COG transfer piping as described above, the pivot axis of the COG does not overlap with the path of the impurities, so that the pressure loss due to the lowering of the turning force does not occur. In addition, the impurity separation is continuously performed without forming a vortex for generating a swirling force in the COG and a separate device for discharging the COG, and the impurities separated from the COG are efficiently removed and adsorbed to the purified COG and not discharged. Further, it is desirable to provide a separator for a COG transfer pipe in which the structure is simple and free installation is possible, and the ease of use is increased.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It is not limited to the embodiment.
