The present invention relates to a flare gas discharge control device, and more particularly, to a flare gas discharge control device configured to stably support and guide a plotter that is raised or lowered by the discharge pressure of flare gas by using an elastic means. will be.

In general, flare gas is a waste gas generated in an oil refinery, etc., and is a gas having volatile and flammable properties.

The flare gas is discharged to the outside through a flare gas discharge device called a flare stack.

A flare stack according to the prior art includes an open discharge port through which flare gas is discharged, and an ignition unit that burns the flare gas at the same time as the flare gas is discharged.

In the case of the flare stack according to the prior art, since it has an open outlet, when the atmospheric pressure outside the flare stack is greater than the gas pressure inside the flare stack (ie, when the internal pressure of the flare stack is lower than the atmospheric pressure), the ignition unit There is a problem in that a backfire phenomenon occurs in which the flow of the flame generated by the reverse flow into the flare stack.

This backfire phenomenon has been a problem of increasing the risk of explosion of the flare stack by abruptly increasing the pressure inside the flare stack.

In order to prevent backfire, a flare stack according to another prior art further includes a purge gas supply device for ejecting purge gas, which is an inert gas, upward from inside the flare stack. By supplying the purge gas through the purge gas supply device, the gas pressure inside the flare stack can always be maintained higher than the external atmospheric pressure to prevent backfire.

Therefore, in order to solve the above problems, the present applicant provides an up/down movable opening and closing plotter that selectively opens and closes the outlet formed at the upper end of the stack unit by the internal pressure of the stack unit. When the internal gas pressure of the unit is higher than the predetermined pressure, it is increased, and when it is less than the predetermined pressure, it is lowered to block the outlet of the stack unit.

In addition, a guide rod is mounted on the lower end of the plotter for opening and closing so that the lifting or lowering movement of the plotter can be stably performed along the longitudinal direction of the stack, and a guide bracket through which the guide rod passes is mounted on the inner surface of the stack. did

However, the flare gas discharge control device configured as described above has a problem in that the stack unit is damaged due to an impact applied to the open top of the stack unit when the floater is raised or lowered by the internal gas pressure of the stack unit. That is, there is a problem in that the stack part is damaged because the heavy floater strikes the upper end of the stack part in the process of being suddenly raised and lowered by the pressure of the flare gas.

Therefore, the present applicant has proposed the present invention in order to solve the above problems, and as a related prior art document, there is a 'flare gas emission control device' of Korean Patent Registration No. 10-1978914.

As shown in Figures 1 and 2, the flare gas discharge control device 100 according to an embodiment of the present invention, the stack unit 200 for guiding the flare gas upward; a plotter 300 seated at the upper end of the stack unit 200 and moving up and down according to the pressure of the flare gas to selectively open and close an outlet formed at the upper end of the stack unit 200; a guide rod 400 provided at a lower end of the plotter 300 and disposed inside the stack unit 200; a guide bracket 500 formed inside the stack part 200 and forming a through hole 500a through which the guide rod 400 passes; And it is provided at a part of the longitudinal direction of the guide rod 400 disposed under the guide bracket 500, and when the plotter 300 rises and opens the outlet, it is compressed, and the plotter 300 descends. and a first elastic means (S1) that is stretched to its original state when the outlet is blocked.

The stack unit 200 is a component that guides the flow direction of the flare gas so that the flare gas rises in the vertical direction. For example, the stack unit 200 may be installed vertically on the ground and may have a hollow cylindrical shape with a constant diameter or a hollow cylindrical shape with a diameter decreasing toward the top.

As described above, an outlet for discharging flare gas to the outside is formed at an upper end of the stack unit 200 . In addition, although not shown in the drawing, an ignition device for burning flare gas may be provided at an upper end of the stack unit 200 .

As shown in FIGS. 1 and 2 , the stack unit 200 configured as described above may be configured as a separable type.

That is, the stack unit 200 includes a flow pipe 210 for guiding flare gas in a vertical direction; and a discharge pipe 220 connected to the flow pipe 210 so as to be communicatively connected and forming an outlet at an upper end through which the flare gas flowing along the flow pipe 210 is discharged.

The discharge pipe 220 is detachably mounted with the upper end of the flow pipe 210, and specifically, the lower end of the discharge pipe 220 and the upper end of the flow pipe 210 may be connected to each other by coupling of flanges formed thereon.

As described above, the reason for configuring the stack unit 200 as a separate type rather than a single type is to insert the guide rod 400 into the guide bracket 500 to be described later before connecting the discharge pipe 220 to the flow pipe 210 and This is to allow the operator to easily perform the work and the work of seating the plotter 300 on the upper end of the flow pipe 210. In addition, it is preferable to configure the stack unit 200 in a detachable type so that the operator can easily perform replacement and maintenance work of the plotter 300, the guide rod 400, and the guide bracket 500.

The plotter 300 is a component that selectively opens and closes an outlet formed at an upper end of the discharge pipe 220 .

Specifically, the plotter 300 has a first operating position (see FIG. 1) blocking the outlet formed at the upper end of the discharge pipe 220 and a second operating position (Fig. 2) can be configured to move up and down between them.

Here, the second operating position is to levitate in the air by the pressure of the flare gas flowing upward from the inside of the stack unit 200 .

For example, when the pressure of the flare gas flowing inside the stack unit 200 is higher than the preset pressure, the plotter 300 receives pressurization of the flare gas as shown in FIG. 2 and can be moved to the second operating position. have. Then, as the outlet of the discharge pipe 220 is opened, the flare gas can be discharged to the outside.

Conversely, when the pressure of the flare gas flowing inside the stack unit 200 is less than the preset pressure, the plotter 300 may be moved to the first operating position as shown in FIG. 1 . Then, the outlet of the discharge pipe 220 may be blocked. At this time, the floater 300 blocks the discharge port of the discharge pipe 220 while being lowered by its own weight.

For reference, the predetermined pressure may be set greater than the sum of atmospheric pressure and pressure due to the weight of the plotter 300 .

While the plotter 300 is raised by the pressure of the flare gas, a phenomenon occurs that the floater 300 is not raised correctly in a predetermined vertical direction due to the flow distribution of the flare gas and is biased to one side or the other side. In addition, when the pressure of the flare gas is high, there is a possibility that the plotter 300 may be separated from the upper end of the stack unit 200. In this way, when the plotter 300 is biased to one side or the other side and rises, it may collide with the ignition device provided at the upper end of the stack unit 300 in the process of descending, resulting in damage to the ignition device.

Also, while the plotter 300 is descending, an instantaneous impact is generated on the upper end of the stack unit 200 or the guide bracket 500, which may damage the device.

The above problem can be prevented by the first elastic means (S1) and the second elastic means (S2) to be described later.

As shown in FIGS. 1 and 2, the first elastic means (S1) has one longitudinal end in contact with the first stopper (G1) provided at the lower end of the guide rod 400, and the other longitudinal end thereof is in contact with the guide rod. It may come into contact with the lower surface of the bracket 500.

In other words, the first elastic means (S1) passes through the through-hole (500a) of the guide bracket (500) and is provided on the guide rod (400) disposed below the guide bracket (500), and one end in the longitudinal direction thereof is It is in contact with the first stopper (G1) and the other end in the longitudinal direction is in contact with the lower surface of the guide bracket (500) so that it can be elastically compressed or stretched between the first stopper (G1) and the guide bracket (500).

As described above, the first elastic means (S1) configured as described above is compressed as shown in FIG. 2 when the plotter 300 is raised to open the outlet of the discharge pipe 220. Conversely, when the plotter 300 descends and blocks the outlet of the discharge pipe 220, it can be tensioned and returned to its original state as shown in FIG.

Therefore, the plotter 300 can be raised correctly in the vertical direction by organic coupling of the first elastic means S1, the guide rod 400, the guide bracket 500, and the first stopper G1, and in particular, the flare A phenomenon in which the floater 300 is separated from the upper end of the discharge pipe 220 due to the discharge pressure of the gas can also be prevented.

In addition, it is provided at a part of the longitudinal direction of the guide rod 400 disposed above the guide bracket 500, and when the plotter 300 is lowered and the outlet of the stack unit 200 is blocked, It may further include a second elastic means (S2) that is compressed and tensioned when the plotter 300 is raised and the outlet of the stack unit 200 is opened.

As shown in FIGS. 1 and 2 , the second elastic means S2 is a guide disposed between the second stopper G2 and the guide bracket 500 provided at the upper portion of the guide bar 400 in the longitudinal direction. It may be provided on the longitudinal portion of the rod 400.

One longitudinal end of the second elastic means (S2) may be in contact with the upper surface of the guide bracket (500) and the other longitudinal end may be in contact with the second stopper (G2).

The second elastic means (S2) configured as described above can be compressed as shown in FIG. 1 when the plotter 300 descends and blocks the outlet of the discharge pipe 220. Conversely, when the floater 300 is raised and the outlet of the discharge pipe 220 is opened, it may be tensioned as shown in FIG. 2 .

Therefore, by organic coupling of the second elastic means (S2), the guide rod 400, the guide bracket 500 and the second stopper (G2). When the floater 300 is lowered by its own weight, shock transmitted to the upper end of the discharge pipe 220 and the guide bracket 500 may be alleviated.

On the other hand, as shown in FIG. 3, the guide bracket 500 is designed to prevent deformation or breakage from the pressing force generated by the first elastic means S1 or the second elastic means S2. 210) is provided at a point where the upper end of the discharge pipe and the lower end of the discharge pipe come into contact with each other, and may be raised or lowered to a predetermined height.

As shown in FIGS. 3 and 6 , the guide bracket 500 forms the through hole 500a and receives pressure from the first elastic means S1 or the second elastic means S2. main frame 510; and an auxiliary frame 520 provided at a circumference of the main frame 510 at a predetermined interval, one longitudinal end connected to the main frame and the other longitudinal end connected to the stack unit 200. can

When the plotter 300 is raised or lowered by the pressure of the flare gas, the main frame 510 is directly pressed by the first elastic means (S1) or the second elastic means (S2) that is compressed or stretched. is a component

A through-hole 500a through which the guide bar 400 passes is formed in the central portion of the main frame 510, and the through-hole 500a may have a larger diameter than the outer diameter of the guide bar 400. Accordingly, when the guide rod 400 is raised or lowered, the guide rod 400 may not come into contact with the inner circumferential surface of the main frame 510 defining the through hole 500a.

A plurality of auxiliary frames 520 may be provided along the circumferential surface of the main frame 510 and spaced apart at predetermined intervals. In one embodiment of the present invention, it is shown in the drawing that three auxiliary frames 520 are provided in the main frame 510, but it is not limited thereto, and the number of at least two or three or more is shown in the main frame 510. may be provided.

In the auxiliary frame 520, a plurality of holes 500b through which flare gas can pass are formed. Therefore, interference of the flow of the flare gas with the auxiliary frame 520 can be minimized.

As shown in FIG. 3, the other end of the auxiliary frame 520 in the longitudinal direction is inserted into the grooves formed at the upper end of the flow pipe 210 and the lower end of the discharge pipe 220, respectively, and the second end provided in the groove of the discharge pipe 220. Pressurization can be received by the third elastic member (S3) or the fourth elastic means (S4) provided in the groove of the flow pipe (210).

The third elastic means (S3) provided in the discharge pipe 220 elastically presses the upper surface of the other end in the longitudinal direction of the auxiliary frame 520, and the fourth elastic means (S4) provided in the flow pipe 210 is the auxiliary frame 520 It is possible to elastically press the bottom surface in the longitudinal direction of.

Therefore, when the pressure of the flare gas becomes higher than the preset pressure and the plotter 300 is raised, as shown in FIG. 4, since the guide bracket 500 is pressurized by the first elastic means S1, the auxiliary frame While the other end in the longitudinal direction of 520 is raised, the third elastic means (S3) can be pressed and compressed.

Conversely, when the pressure of the flare gas becomes less than the preset pressure and the plotter 300 descends, as shown in FIG. 5, since the guide bracket 500 is pressurized by the second elastic means S2, the auxiliary frame While the other end in the longitudinal direction of 520 is lowered, the fourth elastic means (S4) may be pressed and compressed. When a predetermined time elapses in this state, the auxiliary frame 520 is pressed by the fourth elastic means S4 by the elastic modulus of the fourth elastic means S4 and can return to its original position. That is, it can be returned to the position shown in FIG. 3 by being pressed by the fourth elastic means (S4).

The third elastic means (S3) and the fourth elastic means (S4) configured as described above perform a buffering role of mitigating the impact transmitted to the guide bracket 500 when the plotter 300 is raised or lowered.

Accordingly, it is possible to prevent the guide bracket 500 from being deformed or damaged by the first elastic member S1 or the second elastic member S2 according to the repeated upward or downward movement of the plotter 300 .

On the other hand, the upper end of the flow pipe 210 and the lower end of the discharge pipe 220 are provided with a space 530 providing a space in which the auxiliary frame 520 can be raised or lowered.

The space 530 provides a space capable of rising or falling when the guide bracket 500 is pressed by the first elastic means S1 or the second elastic means S2, and precisely, the auxiliary frame ( 520) provides a space where the other end in the longitudinal direction can be raised or lowered. For reference, the space 530 may be formed on a portion of the inner surface of the flow pipe 210 and a portion of the inner surface of the discharge pipe 210 corresponding to the other longitudinal end of the auxiliary frame 520 .

The spacer 230 formed in the discharge pipe 220 provides a space in which the guide bracket 500 can be elevated when the plotter 300 is raised, as shown in FIG. It can be communicatively connected.

The spacer 230 formed in the flow pipe 210 provides a space for the guide bracket 500 to descend when the plotter 300 descends as shown in FIG. It can be communicatively connected.

Therefore, the guide bracket 500 can be smoothly moved up or down without interfering with the inner surface of the flow pipe 210 or the discharge pipe 220 by the spacer 530 formed on the flow pipe 210 and the discharge pipe 220. have.

Meanwhile, as shown in FIGS. 3 to 6 , a blocking plate 530 may be provided at the other side of the auxiliary frame 520 in the longitudinal direction to block the flow of flare gas into the spacer 230 .

The blocking plate 530 may be provided on an upper surface and a lower surface of the other end side in the longitudinal direction of the auxiliary frame 520 , respectively.
