Description

EXTINGUISHING AUTO ROOM FOR EXTINGUISHING PETROLEUM AND GAS WELLS FIELD OF THE INVENTION The present invention relates to a funnel-type second-generation self-extinguishing room, which is connected to an extinguishing system, especially an oil and gas extinguishing system and an extinguishing device associated with oil and gas wells.

BACKGROUND OF THE INVENTION The extinguishing process can be done in many ways. For example, large quantities of extinguishing materials are expelled to extinguish. Fire trenches can form next to the burning gas well to reach the fire point from the bottom. Large amounts of concrete can be placed over the well's nozzle, or a tall tube can be placed over the well's nozzle to raise the flames. In addition, an explosion can be used for extinction. In case of explosion, extinguishing materials can be expensive, and can damage equipment around the burning gas well and consume time. As a result, the time for extinction may last for several weeks or months. Large expensive equipment is used for a long time, and this can lead to damage to the pipes at the bottom of the wells. Large amounts of fuel (oil or gas) are wasted, and this will contaminate the environment. In addition, these have significant innces on people's lives, and environmental pollution is related to the loss of important energy resources in most countries, and therefore is considered as a great economic loss. There is also damage from the process of cleaning these materials and burning fuels, because they can establish a long-term pollution, which may require large amounts of funds. These remnants of the fire can spread to distant places through rivers or air, and this can lead to dangers for humans, animals, birds and plants. The current situation makes it clear that the method used in the fire is not efficient. Therefore, it is necessary to find an alternative method that can save time, energy and money and reduce the hazards mentioned above. A prior invention has a certified authentication under a certified industrial model No. 1 131 on February 28, 2010 from the City for Science and Technology of King Abdul-Aziz (KACST), and has been registered in the Patent Office of the Council for Gulf Cooperation under OP / B / 2007/7575 on January 7, 2007. It is noted that the irregular ejection of large quantities of burning materials can lead to high pressure in the room. extinction for some wells, which is sufficient to cause expulsion from the extinguishing room itself, and to give rise to the failure of the previous invention. To overcome this dilemma, the weight of the system increases, so that the system is more stable. The inventors also add some advantages to the system. For example, some holes are formed in the side of the extinguishing room. The holes automatically work in case the pressure increases, and automatically close in case the pressure is reduced. In this way, the operating time is reduced to a few minutes, instead of several weeks. As a result, it is possible to save time, energy and money, and save the lives of firefighters. The self-extinguishing room can reduce the risk of the gas well. In addition, the self-extinguishing room can preserve the environment by reducing the time in the fire, shorten the time in combustion, and reduce the harmful substances produced by a fire.

BRIEF DESCRIPTION OF THE INVENTION The object of the invention is to overcome the disadvantages in the state of the art by means of providing a self-extinguishing room that can reduce the danger of the gas well, can take care of the environment by reducing the combustion time, shorten the time of the fire, and can reduce the harmful substances produced by a fire.

In order to achieve the above objective, the technical solution of the invention relates to a self-extinguishing room for the extinguishing of oil and gas wells, characterized in that said self-extinguishing room comprises a housing that is filled with the extinguishing materials, a upper portion of the housing is a truncated cone while a lower portion is a cylinder body, a primary orifice is disposed on said truncated cone, the pressure balancing holes are disposed on the side face of said truncated cone, a hose is further installs on the side face of said truncated cone to eject large quantities of the extinguishing materials, a control valve is disposed on the side face of said cylinder body for the self-extinguishing materials, and a package is installed on the lower surface of said cylinder body.

A cover of the holes is articulated over said pressure balancing holes, and a recovery spring is installed between said cover of the holes and said housing.

A spring for the opening of the control valve is installed on said control valve.

A cover of the primary orifice of multiple layers is disposed over said primary orifice.

On the surface of said housing and said hose, a thermal insulating layer is provided and coated with fire resistant materials.

The present invention is a self-extinguishing room of the second generation. The present invention can be considered as the second mode of a prior invention having a certified authentication under a certified industrial model No. 1 131 on February 28, 2010 of the City for Science and Technology of King Abdul-Aziz (KACST) , and has been registered in the Patent Office of the Council for Gulf Cooperation under OP / B / 2007/7575 on January 7, 2007. Through the previous invention, we find that it can fulfill that mission. The second generation of the self-extinguishing room expels the extinguishing materials inside one or all the funnels. By mixing the extinguishing materials and the burning materials, it is possible to reduce the concentration of the burning materials. Extinguishing materials include, but are not limited to, dry carbon dioxide dust as well as other materials that can be used in a fire. The funnel can suppress the flames, and can isolate the flames of oxygen in the surrounding air. The funnel can also more efficiently save the space that is required to melt the steam from the burning materials and the extinguishing materials. The extinguishing materials are expelled in an adequate amount to reduce the concentration of the flowing materials. In addition, flowing materials and extinguishing materials are mixed at a concentration lower than the concentration that is necessary to burn these materials. During the use of the self-extinguishing room, the balance between the pressure of expulsion of the materials in combustion and the pressure of expulsion of the extinguishing materials is controlled by ventilation holes. Since the pressure balance is properly controlled, it is possible to mix the burning materials and the extinguishing materials without influencing the conditions of the room. extinction or reduce its efficiency of operation, and to obtain a more accurate result. The bottom of the funnel can be placed on the surface of the soil or water. The bottom has a diameter of approximately 3-4 meters, to inhibit the extinguishing materials or release the extinguishing materials from the hole in the upper portion. In the event that the extinguishing materials are mixed with the vapor of the burning materials (the flames), it is possible to extinguish them more efficiently. The funnel can be formed by a strong and heat resistant material, or coated with one or more layers of the heat insulating material on the inside. The funnel can be molded to have a circular, triangular, or square shape, or it can be shaped to have a pyramidal or wave shape. The bottom of the funnel can extend in parallel in a small, intermediate and large complex shape, according to the position, height, size and quantity of materials flowing from the well. The extinguishing materials are expelled from a specific tank placed on the surface of the funnel. The hose is designed to expel materials under high pressure. The exterior of the hose is protected by a heat-insulating material, and covered closely. The extinguishing materials are expelled according to the desired temperature and the susceptibility of the heat insulating materials, and they are automatically ejected when they make contact with the surface near the gas well. The funnel can be transported by helicopter or along a bridge that extends into the well, or it can be transported by a remote-controlled transportation tool. Care has been taken in the design so that the combustion substances expelled from the well should be located below the bottom of the funnel, and that the funnel should have a diameter corresponding to the flame or slightly smaller than the diameter that is effective for mixing the flame and the extinguishing materials. For these reasons, many measures have been applied in the individual hole of the funnel. After placing the funnel on the expelled substances by the combustion gas well, the embedment should be fixed as much as possible, and this is mainly achieved by the weight of the funnel. The bottom surface of the funnel is oriented towards the surface surrounding the well, to prevent the extinguishing materials from leaking out of the funnel and to prevent the surrounding air from entering the funnel. The extinguishing materials in the funnel are automatically ejected, until the flames are extinguished. Once the combustion gas well is extinguished, a cooling process begins. The cooling process is preferably carried out before and during the extinguishing process. Any suitable material in the surroundings is used to facilitate the cooling of the well, in order to prevent the flames from burning again.

The invention has the following advantages and beneficial effects. In the second mode of the self-extinguishing room for the extinction of oil and gas wells, the weight of the system is increased, so that the system is more stable. The inventors also add some advantages to the system. For example, some holes are formed in the side of the extinguishing room. The holes automatically work in case the pressure increases, and automatically close in case the pressure is reduced. In this way, the operating time is reduced to a few minutes, instead of several weeks. As a result, it is possible to save time, energy and money, and save the lives of firefighters. In this way, the self-extinguishing room can reduce the risk of the gas well. In addition, the self-extinguishing room can preserve the environment by reducing the time in the fire, shorten the time in combustion, and reduce the harmful substances produced by a fire.
