A kind of airbag type temporary gas storage device

Abstract

The invention relates to oil gas recycle equipment, and particularly relates to a gasbag type temporary gas storage device. The temporary gas storage device is provided with a protective cover body which consists of a bottom plate, a top plate and support rods arranged at intervals, wherein a gas inlet valve and a gas outlet valve are respectively arranged on two sides of the protective cover body; a gasbag body which is used for connecting the gas inlet valve and the gas outlet valve is arranged in the protective cover body; an infrared inductor and a controller are also arranged on one side of the protective cover body; and the controller is electrically connected with the gas inlet valve, the gas outlet valve and the infrared inductor. Being simple and reasonable in design, low in manufacturing cost, capable of ensuring the purity of the stored oil gas, high in safety and convenient to assemble and operate, the gasbag type temporary gas storage device is suitable for the oil gas recycle in oil fields.

Description

Technical field: [0001] The invention relates to petroleum gas recovery and utilization equipment, in particular to an air bag type temporary gas storage device. Background technique: [0002] The crude oil in the oil field enters the oil storage tank through the collector, and a large amount of gas will be generated in the oil storage tank, which is rich in combustible gas. For these gases, the traditional treatment method is to directly discharge them into the atmosphere from the vent valve on the top of the oil storage tank or ignite them at a high place. This method not only causes a lot of waste of petroleum gas, but also produces a large amount of polluting gases such as carbon dioxide. Great damage to the atmosphere and the ozone layer. At present, the main measures taken are: introduce these gases into the oil-gas separator, and liquefy some of the gases through condensation. Imported into the gas storage tank for temporary storage, and then reused. Since the gas ...

AI Technical Summary

Problems solved by technology

Since the gas storage tank is made of steel, it is bulky, heavy and requires special equipment for transportation, and the production and installation costs are high; in addition, since the gas storage tank is filled with air before use, after the petroleum gas is introduced into the gas storage tank, the oil The purity of the gas will be greatly reduced, and it will increase the risk of explosion. Once the gas storage tank explodes, due to the material, volume, weight and other factors of the tank itself, its destructive power is extremely strong, even no less than that of a bomb.
