Description
Technical Field
The utility model belongs to oil storage tank equipment field specifically relates to a reduce because storage tank breathes storage tank of the built-in magnetic force air pocket of the waste gas displacement of production.
Background
The refining industry mainly comprises storage tanks such as an acid water tank, a waste oil tank, an oil product intermediate tank and the like, and waste gas generated by breathing contains volatile substances such as hydrocarbons, hydrogen sulfide, organic sulfides and the like, so that not only can serious environmental pollution be caused, but also a large amount of resources can be wasted. The process of venting and aspirating the tank is called "breathing", generally breathing due to the variation of the liquid level caused by the feeding and the discharging is called big breathing, while breathing due to the fluctuation of the pressure inside the tank caused by the variation of the diurnal temperature difference is called small breathing.
Because the generated waste gas is volatilized from the liquid stored in the tank body, a floating roof design is adopted in the design of a general storage tank, namely a floating partition plate is added above the stored liquid to cover the liquid level so as to reduce the contact area of the liquid and the gas and achieve the aim of reducing the volatilization amount. However, this technique cannot substantially solve the problem of exhaust gas emission with large and small breaths, and can reduce the exhaust gas concentration to some extent. Except that increasing the kickboard, in order to prevent that the storage tank from leading into too much oxygen and causing the potential safety hazard and oil oxidation when breathing in, the storage tank will generally be provided with the nitrogen seal, and to the jar body supplementary nitrogen gas in order to keep apart the air when the storage tank breathes in, the cost in the storage tank maintenance use is increased by a wide margin to the consumption of nitrogen gas.
Based on the breathing characteristics of the storage tank, if the atmosphere can not be mixed with the waste gas in the tank body during air suction, the maintenance and use cost of the storage tank is greatly reduced, and the oil product is prevented from being oxidized, thereby being beneficial to the stability of the property of the oil product; when the storage tank feeding was carried out the heavy respiration, the gas volume that gets into follow-up exhaust treatment device was great, pollutant concentration in the waste gas is higher, will increase exhaust treatment device's load, if the gas of exhaust does not contain waste gas or the waste gas volume of production is less when exhaling, with the cost that follow-up waste gas of greatly reduced was administered, is favorable to the steady long-term operation of exhaust treatment device.
CN201240626Y discloses an external elastic breathing gas cabin, which is arranged outside a storage tank and used for collecting waste gas discharged when the storage tank exhales, and waste gas in the gas cabin returns to the storage tank when the storage tank inhales. When the feeding of the storage tank is changed from an empty tank to a full tank, the gas quantity exhaled by the storage tank is equivalent to the nominal capacity of the storage tank, so that the volume of the elastic breathing gas bin is larger than the nominal capacity of the storage tank, the volume of the elastic breathing gas bin after being filled with waste gas is larger, and the waste gas is mainly composed of flammable and combustible components, so that the potential safety hazard is larger; the gas bin is an external gas bin, and the top of the storage tank needs to be provided with an oil measuring port, and the tank body needs to be provided with necessary storage tank accessories such as a ladder, so that the gas bin is difficult to arrange, and the gas bin, the storage tank body and the accessories are difficult to ensure that the sealing is not leaked; the external air bin is exposed in the atmosphere, and is blown by wind, exposed to the sun and drenched by rain, so that the aging speed is high, the service life is short, and the use cost is high; there is obvious defect when this gas storehouse deals with bad weather, especially during extreme weather such as storm wind, typhoon, tornado, the lifting surface area of storage tank when having increased wind by a wide margin, the part or the regional atress that lead to the gas storehouse to be connected with the storage tank easily are great, lead to storage tank local area to be damaged, because the gas in the gas storehouse is inflammable explosive gas, if there is leakage or lightning-arrest measure to set up in place in the gas storehouse when weather such as face thunderstorm, then there is great potential safety hazard.
CN202828613U discloses a diaphragm type oil storage tank, which adopts a structure with an internal air bag fixed inside the top of the tank body to isolate the contact between oil vapor and air. However, the storage tank is based on a horizontal storage tank without a floating plate, and the problem of an exhaust gas outlet in special cases is not considered; after the liquid level of the storage tank is increased to a certain degree, the air bag can float on the liquid level of an oil product, so that the air bag is aged and the service life of the air bag is shortened; and the storage tank has no antistatic design for the materials used by the built-in air bag, and has potential safety hazard in the use process.

Detailed Description
The following detailed description of the present invention, taken in conjunction with the accompanying drawings and examples, will enable those skilled in the art to more fully understand the present invention without limiting it in any way.
The utility model provides a storage tank of built-in magnetic force air pocket, include: jar body 1, kickboard 2, first breathing mouth 5, magnetic air bag 3, the inner wall of upper portion is provided with a plurality of magnetic force component 10 in the magnetic air bag 3, and between kickboard 2 and first breathing mouth 5 were arranged in to air bag 3, and 3 upper end openings of magnetic air bag are through first breathing mouth 5 and atmosphere intercommunication, and 3 lower extremes of magnetic air bag are fixed in on the kickboard 2. The top of the tank body 1 is provided with a second breathing port 7, the second breathing port 7 is connected with a pressure control system 8, and a magnetic element 10 is arranged at the middle upper part of the magnetic air bag 3.
As shown in fig. 1, after the magnetic air bag 3 is placed in the tank body 1 for the first time, compressed air is filled into the magnetic air bag 3 through the first breathing port 5, at this time, the magnetic air bag 3 is completely unfolded, the periphery and the upper part of the magnetic air bag 3 are tightly attached to the inner wall of the tank body 1, the magnetic element 10 is adsorbed on the inner wall of the tank top of the tank body 1 and/or the upper part of the tank body 1 and fixes the magnetic air bag 3, so that the magnetic air bag 3 occupies the space on the floating plate 2 in the tank body 1, and at this time, the top opening of the magnetic air bag 3 is communicated with the atmosphere. When the storage tank is subjected to heavy breathing in the operation process, when the storage tank is fed, the floating plate 2 moves upwards, the magnetic air bag 3 is gradually accumulated on the floating plate 2, and meanwhile, the gas in the magnetic air bag 3 is discharged through the breathing port 5; when the storage tank is discharged, the floating plate 2 moves downwards, the lower part of the magnetic air bag 3 is gradually stretched, and air enters from the breathing port 5.
