Description

[0001] COOLING AIR CIRCULATION APPARATUS OF FLARE BOOM [0002]

The present invention relates to an apparatus for cooling a flare tower which is a structure for burning and discharging gas in an offshore plant. And more particularly, to a cooling device for suppressing an increase in temperature due to a flame by circulating air into a structure of a flare tower.

In general, waste gas, which is flammable and poisonous, is generated during the operation of collecting oil that is buried in the earth or the sea floor.

Therefore, any facility that incineration of flammable and toxic waste gas is replaced with toxic or non-flammable material and then released into the atmosphere is called a flare system or a flare stack.

The flare system is a chimney type incinerator, which consists of a flare tower that forms a structure, a flare tip that burns offgas, a burner, and an ignition device.

Therefore, the flare tip is always installed in the flare tip to collect the waste gas generated during the refining process and collect the waste gas, so that the flare tip is installed at a considerably high position on the ground or in the water.

However, conventionally, since the flare tip is continuously exposed to high temperature due to the combustion of waste gas and the heat is radiated to the flare tower around the flare tip, the flare tip and the thermal deformation of the flare tower adjacent to the flare tip, We had to check occasionally.

The flare tip is equipped with safety devices such as backfire prevention device to prevent back fire but it is not easy to install a device for cooling due to the characteristic of the flare tip located at the high place.

Also, in most cases, the flare tip is located at the top of the flare tower structure, so that the operator has to spend a lot of manpower and expense to check for thermal deformation or cracks from time to time, and the heat near the flare tip may put the operator at risk However, checking and repairing thermal deformation or cracks did not fundamentally contribute to extending the durability of the flare towers and flare tips.

It is an object of the present invention to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a flare tower structure which is an essential component of a flare system, To an apparatus for cooling the periphery.

According to an aspect of the present invention, there is provided an air circulation type cooling apparatus for a flare tower, comprising: a sub-post for distributing loads by connecting at least two main posts to a main post, And an air circulation cooling device which is formed at one end of the flare tower and in which air is circulated by forming a circulation cooling path in a flared tip for burning the gas and an empty inner space of the main post and the subpost.

Alternatively, the air circulation cooling apparatus includes an air circulator that injects air into one end of the circulation cooling path and discharges the circulated air to the other end.

The air circulator includes an air conditioning unit so as to control the temperature of circulated air.

Alternatively, the circulation cooling path includes at least one heat insulation pipe connected at one end to the air circulator at the inner side and opened at the other end inside the circulation cooling path.

And, the heat insulating pipe is located at one end opened to the branch of the circulation cooling path.

Alternatively, the open end of the heat insulating tube is inclined so that the discharged air induces a vortex inside the circulating cooling path.

And, the circulation cooling path includes at least one inner circumferential protruding vortex that causes the flowing air to generate a vortex.

Alternatively, the circulation cooling path may be formed to be circulated via the flared tip.

In order to solve the above problems, the air circulating type cooling apparatus of the flare tower of the present invention utilizes the flare tower structure, which is an essential component of the flare system, so that the additional cost for installation is not large, So that the temperature around the flare tip can be kept low without affecting the combustion of waste gas of the flare tip. In addition, the circulating cooling air circulates air vortically to the inside of the circulating cooling path to increase the circulation efficiency, and air having a low temperature is further supplied through the heat insulating tube until the circulation cooling path having a long length is further supplied. .

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