Description

Multi flare tip apparatus

The present invention relates to a multi-type flare tip device, and more particularly, in order to control the pressure generated in a flare stack device installed in a petroleum drilling, oil refinery or petrochemical plant, etc., surplus gas or waste gas inside the device is ejected to the outside. It relates to a multi-type flare tip device for combustion.

In recent years, as industrialization and industrialization accelerate, the consumption of natural resources (oil, natural gas, etc.) is gradually increasing, and the stable production and supply of natural resources with limited reserves is emerging as a very important problem.

Offshore plants operate for about 3 to 40 years after they are installed at oil or gas mining sites, so the design considerations are also quite demanding. Various and high-difficulty technologies are required to secure stability against fire and explosion due to the production of petroleum products as well as climatic effects such as wind and waves and special environmental conditions at sea.

In addition, due to the recent increase in demand for petroleum resource development in the deep sea of 1,000 m or more, technology is being secured and developed in a variety of ways. There is a trend to develop offshore plants for

As a result, demand and price of offshore plants are also rising while demand for energy and resources is increasing and price soaring around the world.

In particular, offshore drilling facilities ranging from Gravity Based Structures, Fixed Platform Structures, Floating Structures, and Semisubmersible Structures are expected to continue steadily.

FPSO (Floating Production Storage and Offloading), an offshore plant designed to function as a floating oil production, storage, and offshore refining facility for transport to an onshore refinery, is a facility designed to work in the deep sea. FPSO construction is increasing in line with the development of deep-sea resources due to its free movement and high usability.

FPSOs are currently being used to produce crude oil or natural gas in oil fields. For example, LNG FPSOs are being actively developed due to the depletion of oil fields and an increase in demand for clean fuels. In deep-sea oil field development, Oil FPSO or LNG FPSO is a floating offshore refinery that can refine, store, and transport crude oil or natural gas while floating at sea.

At the topside of the FPSO, a flare system is provided to prevent accidents that may occur at the FPSO by burning waste gas generated in the process of refining drilled crude oil and gas in emergency situations.

In addition, the flare system includes a flare tip, which is a facility installed at the top of a flare stack as shown in FIG.

A flare tip can be divided into an HP tip (high pressure tip) and an LP tip (low pressure tip) according to the gas injection pressure, and a subsonic tip according to the gas injection speed at the nozzle outlet. and sonic tip.

The sonic tip can inject the surplus gas at a speed higher than the speed of sound (supersonic speed of Mach 1 or more), and has the advantage that combustion efficiency can be increased through this injection speed.

However, since the injection velocity of the surplus gas exceeds the speed of sound, there is a sharp difference in velocity between the gas injection airflow that exceeds the velocity of sound and the atmosphere near the flare tip (airflow that does not reach the speed of sound). There is a problem that incomplete combustion occurs.

In particular, since such a flared tip is necessarily accompanied by a high-temperature combustion reaction, radiant heat is generated by the flame, and various types of tip nozzles are formed.

In addition, there is an urgent need for a configuration capable of simultaneously burning a large amount of gas while eliminating the stagnation of the flare gas.

According to the present invention, the burner part ignites toward the tip nozzle part installed on the first tip arm part without having to be equal to the number of tip nozzle parts, and the tip nozzle part installed on the adjacent second tip arm part is disposed on the first tip arm part. There is an advantage of spontaneous ignition by the flame of the tip nozzle part installed in the

In addition, the windshield unit blocks strong wind or impact from the outside to protect the tip nozzle arm, smooth the flow of flare gas, and suppresses strong radiant heat from spreading to the surroundings.

In addition, there is an advantage in that the fixing unit holds the upper vertical portions of the first and second tip arm portions to prevent the shape from being distorted or spread due to an external impact or wind, and at the same time to prevent its shape from being deformed due to high heat during combustion.

In addition, since the first tip arm part and the second tip arm part arrange the tip nozzle parts adjacent to each other at 60° intervals along the circumference of the tip barrel part, the flame is concentrated to solve the incomplete combustion, and it is possible to burn more strongly with a synergistic effect. There is an advantage.

In addition, the tip nozzle part has a lantern shape, and the flare gas ejected from the tip of the tip nozzle arm part can be widely diffused into the atmosphere without being concentrated at any one point in the atmosphere when it is ejected, thereby reducing noise and incomplete combustion.

In addition, in the multi-type flare tip device 100 according to an embodiment of the present invention, the lower part of the tip barrel part 110 is a flange type, so that it can be replaced in case of damage or failure, and the lower supply pipe (F) and the bolt / nut It can be configured by fastening.

As shown in FIGS. 2 to 4 and 8, the first tip arm part 120 has a hollow elbow shape that is branched at 45° from the lower side of the tip barrel part 110 and bent vertically. of the pipe, branched from the tip barrel part 110 installed on the upper part of the lower supply pipe F for supplying the flare gas, and serves as a path through which the flare gas in the tip barrel part 110 is discharged to the outside.

That is, the first tip arm part 120 has an elbow shape that is branched at 45° and is branched from the center of the tip barrel part 110 to the side like a tree branch. It has a configuration that is easy to discharge the same flare gas to the atmosphere.

At this time, three first tip arm parts 120 are radially branched from the tip barrel part 110 by 120 degrees along the circumferential direction of the tip barrel part 110 .

As shown in FIGS. 2 to 4 and 8, the second tip arm part 130 has a hollow elbow shape that is branched at 45° from the upper side of the tip barrel part 110 and bent vertically. of the pipe, branched from the tip barrel part 110 installed on the upper part of the lower supply pipe F for supplying the flare gas, and serves as a path through which the flare gas in the tip barrel part 110 is discharged to the outside.

That is, the second tip arm part 130 has an elbow shape that is branched at 45° and branches like a tree branch from the top of the tip barrel part 110 to the side. It has a configuration that is easy to discharge the flare gas to the atmosphere.

At this time, three second tip arm parts 130 are radially branched from the tip barrel part 110 by 120 degrees along the circumferential direction of the tip barrel part 110 .

In this way, each of the first tip arm part 120 and the second tip arm part 130 alternates in the circumferential direction of the tip barrel part 110 as shown in FIGS. 3 and 7 , the tip barrel part 110 . It is uniformly branched by three radially from

This is because when the flare gas such as surplus gas or waste gas is discharged into the atmosphere and burned, the outlets (or outlets) are disposed adjacently at intervals of 60° along the circumferential direction of the tip barrel part 110, so that more than one is burned. By burning adjacent to each other, incomplete combustion is eliminated and more powerful combustion can be achieved through a synergistic effect.

In addition, each of the first and second tip arm portions 120 and 130 is three at equal intervals of 60° along the circumferential direction of the tip barrel portion 110 as shown in FIG. 3 .

As shown in FIGS. 2 to 5 and 8 , the tip nozzle arm unit 140 has a hollow cylindrical shape connected to an upper portion of any one of the first tip arm unit 120 and the second tip arm unit 130 . As a result, the support 141 is provided therein.

In addition, the tip nozzle arm unit 140 is a passage through which flare gas such as surplus gas or waste gas passes through either the first tip arm unit 120 or the second tip arm unit 130 and is ejected to the atmosphere or to the outside.

It is possible to replace the tip nozzle arm 140 by attaching and detaching it without doing so.

As shown in FIGS. 2 to 5 and 8 , the tip nozzle unit 150 has a streamlined, lantern-shaped surface and is inserted a predetermined depth into the upper part of the tip nozzle arm 140 . It is placed on the support 141 .

In addition, the tip nozzle unit 150 is not concentrated in any one point in the atmosphere when flare gas such as surplus gas or waste gas ejected from the tip of the tip nozzle arm unit 140 is diffused widely into the atmosphere to properly interact with the air. Mixing reduces noise and allows complete combustion to occur.

In addition, the tip nozzle part 150 has a surface of the tip nozzle part 150 that is in contact with the flare gas so that the flare gas flows along the surface of the tip nozzle part 150 and is diffused and dispersed into the atmosphere. It can be installed and adjusted to be spaced apart from the arm 140 at a predetermined interval.

Accordingly, the flare gas ejected between the tip nozzle arm unit 140 and the tip nozzle unit 150 flows into the tip nozzle arm unit 140 spaced apart from the tip nozzle arm unit 140 and the tip nozzle unit 150. It comes into contact with the lower end of the tip nozzle part 150 therebetween, and then flows upward along the surface of the tip nozzle part 150 .

In particular, the tip nozzle unit 150 has a streamlined lantern shape on the surface, and the flare gas ejected between the tip nozzle arm unit 140 and the tip nozzle unit 150 is fast along the surface of the tip nozzle unit 150 .

For reference, the flare gas ejected between the tip nozzle arm part 140 and the tip nozzle part 150 is the surface of the tip nozzle part 150 due to the Coanda effect (the effect of flowing a fluid along a curved surface). When the flow of the flare gas reaches the separation point (the upper end of the lantern shape) at which the flow of the flare gas loses momentum while flowing along, it no longer flows along the surface of the tip nozzle part 150 and away from the tip nozzle part 150 to the outside. It has the characteristic of spreading and a vortex is generated with the air in the atmosphere, so smooth mixing is possible.

In addition, the tip nozzle portion 150 is further provided with a gripping ring portion 151 at the upper end. This is to smoothly move the weighted tip nozzle part 150 by hanging it on the ring part 151 .

That is, the fixing unit 180 is a hub-shaped fixing member extending radially from the center like a tire wheel, and holds the upper vertical portions of the first and second tip arm units 120 and 130 to prevent external shock or damage. It prevents the shape from being distorted or opened by the wind, and at the same time, it also prevents its shape from being deformed due to high heat during combustion.

As shown in FIG. 5 , the air lock seal unit 190 is installed inside the first tip arm unit 120 and the second tip arm unit 130 , and has a hollow truncated cone shape that becomes narrower toward the upper side. restrain

That is, due to the configuration in which the air lock chamber unit 190 has a narrow outlet, such as a funnel shape, if the flare gas passing through the air lock chamber unit 190 lowers the gas ejection pressure to flow in the counterflow direction, As shown, the backflow is suppressed by being caught in the airlock seal unit 190 , and at the same time, it collides with the gas rising from the first tip arm unit 120 or the second tip arm unit 130 to prevent the reverse flow.
