Detailed Description

The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.

The utility model provides an oil gas recovery equipment for oil depot, oil gas recovery equipment for oil depot locates on the oil storage tank 1, including breather valve 2, breather valve 2 connects oil storage tank 1, 2 exports of breather valve are provided with connecting

pipe

3, 3 non-vertical settings of connecting pipe and its other end connect recovery tube 4, connecting pipe 3 with recovery tube 4's tie point is located the upper portion of recovery tube 4 bottom surface, 4 upper end detachable of recovery tube are provided with first recovery section 6 and second recovery section 7, first recovery section 6 is located 7 belows are retrieved to the second, be equipped with oil absorption material 8 in the first recovery section 6, be equipped with active carbon 9 in the second recovery section 7, second recovery section 9 intercommunication atmosphere.

Specifically, by providing the breather valve 2, the oil-containing gas generated in the oil storage tank 1 can be freely discharged to the outside of the tank body. The connecting pipe 3 is provided to feed the oil-containing gas discharged from the breather valve 2 into the recovery pipe 4 for recovery. At the same time, it is necessary to define the non-vertical arrangement of the connection tube 3, considering the following problems: because in this embodiment, retrieve through two recovery sections the oil in the oily gas, and set up in the first recovery section 6 of lower part be the oil absorption material 8, after oil absorption material 8 absorbed more oil, oil can condense into the liquid drop on oil absorption material 8, the part oil on the oil absorption material 8 of this moment drips and can drop, but at this in-process, some particulate matters in the oil absorption material 8 can drop, if with the vertical setting of connecting pipe 3, then probably mix in the oil that has the particulate matter drips and can directly get into in the oil storage tank 1 for the oil by the pollution in the oil storage tank 1. Therefore, the connecting pipe 3 is limited to be arranged vertically, and the probability that oil drops drop into the oil storage tank 1 can be reduced.

In some embodiments, in order to further prevent oil drops from dripping into the oil storage tank 1, the connecting pipe 3 may be inclined or horizontally disposed, and when the connecting pipe 3 is inclined, the connection between the connecting pipe 3 and the breathing valve 2 is taken as a reference, so as to be divided into two cases: when the connection pipe 3 is disposed obliquely upward, the inclination angle thereof is required to be not more than 30 °, and when the connection pipe 3 is disposed obliquely downward, there is no requirement for the inclination angle thereof. Above three kinds of mode that set up, all can effectively avoid oil to drip directly instil into 1 insides of oil storage tank.

The connection end of the connecting pipe 3 and the recovery pipe 4 is located on the upper portion of the bottom surface of the recovery pipe 4, and when oil drops on the oil absorbing material 8 drop, the oil drops drop into the bottom of the recovery pipe 4, so that the subsequent recovery of the dropped oil is facilitated.

Meanwhile, in the embodiment, the oil-containing gas is recycled by adopting a two-section recycling mode, and the two recycling sections are detachably arranged at the upper part of the recycling pipe 4. Meanwhile, for the lower first recovery section 6 (relative to the second recovery section 7), the inside of the first recovery section is filled with oil absorbing materials 8, and these oil absorbing materials 8 can be generally selected from materials with high oil absorbing speed and large oil absorbing capacity, such as oil absorbing felt, oil absorbing cotton, etc., which can rapidly absorb most of the oil molecules in the oil-containing gas; for the second recovery section 7 (relative to the first recovery section 6) located at the upper part, the inside of the second recovery section is filled with activated carbon 9, and the activated carbon 9 has a certain adsorption effect on oil products, but the adsorption amount is relatively low, but the adsorption speed is relatively high and relatively trace amount of oil can be absorbed. This is so arranged because: the oil-containing gas volatilized from the oil storage tank 1 has a high oil-containing partial pressure, and therefore, it is first necessary to absorb the oil-containing gas by using the oil absorbing material 8 having a high oil absorbing speed and a large oil absorbing amount, and after the oil absorbing material 8 absorbs the oil-containing gas, a small amount of oil molecules still exist in the remaining gas, and therefore, the absorption is performed by using the activated carbon 9 having a high absorption accuracy, so that the exhaust gas contains substantially no oil molecules.

Meanwhile, the two recycling sections are arranged to be detachable, so that the materials can be replaced conveniently: any one of the materials has an upper limit of absorption, and therefore, it is provided to be detachable, and when the absorption effect becomes poor, it can be quickly replaced.

Generally speaking, the oil drops that drop into in the recovery pipe 4 need just can utilize after handling it, but because in this embodiment, the impurity in the oil drop usually only is oil absorption material granule, can mix with a part of active carbon granule occasionally, simultaneously because oil absorption material 8 and active carbon 9 are all insoluble in oil, consequently, only need adopt simple filtration can carry out recycle with these oil drops. Therefore, an oil discharge pipe 5 is provided at the lower end of the recovery pipe 4, a strainer 11 is provided inside the oil discharge pipe 5, and the other end of the oil discharge pipe 5 extends into the oil storage tank 1. Oil drops drop into the recovery pipe 4 and then enter the oil discharge pipe 5, and are filtered by the filter screen 11 and then enter the oil storage tank 1.

However, considering that the oil-containing gas can enter the oil discharge pipe 5 through the recovery pipe 4, the function of the breather valve 2 is weakened, and the volatilization of the oil is promoted (after part of the oil is volatilized, the volatile matter is discharged, and the volatilization of the oil is accelerated by phase change), therefore, the tail end of the oil discharge pipe 5 is also provided with the U-shaped pipe section 10, the dropped oil drops can generate a liquid seal effect after entering the U-shaped pipe section 10, the oil-containing gas is prevented from entering the recovery pipe from the oil discharge pipe 5, and meanwhile, the filtered oil does not enter the oil storage tank 1.

When the device is used, the whole device is installed, a certain amount of oil is injected into the U-shaped pipe section 10 to form a liquid seal, when oil volatilized in the oil storage tank 1 is excessive, oil-containing gas is discharged through the breather valve 2 and enters the interior of the recovery pipe 4, the oil-containing gas moves upwards, a large amount of oil molecules in the oil-containing gas are absorbed by the oil absorption material 8 when passing through the first recovery section 6, the oil-containing gas continues to move upwards to the second recovery section 7, the oil molecules are basically adsorbed under the adsorption action of the activated carbon 9, and the residual gas is emptied. After the oil absorption material 8 absorbs a large amount of oil, oil molecules are condensed into oil drops on the oil absorption material 8, part of the oil drops drop to the bottom of the recovery pipe 4, the oil drops are counted into the U-shaped pipe section 10 after being filtered, the pressure on one side of the U-shaped pipe section 10 is increased, and part of the oil in the U-shaped pipe section 10 is promoted to be discharged until the pressure balance is achieved again.

Those skilled in the art will appreciate that the above-mentioned method of use is only an explanation of the present embodiment and not a limitation of the present invention, and those skilled in the art can use the apparatus of the present embodiment to perform experiments by different methods according to the actual situation.

The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
