Problems solved by technology
This kind of sediment will not only reduce the actual capacity of the storage tank, but also reduce the quality of the petrochemical oil stored in the tank. In severe cases, it will also block the oil pump, pipeline valve, discharge port, etc., causing inaccurate oil volume monitoring and difficulty in sending and receiving oil. series of questions
In order to eliminate these problems caused by sediments in petrochemical oil storage tanks, it is generally necessary to invest a lot of manpower and material resources to regularly drain and clean the storage tanks. At the same time, it needs to be left empty for a long time during the cleaning process, which will reduce the utilization rate of the oil storage tanks.
[0003] In addition, the transfer between oil storage tank groups, external input or output of oil storage tank groups requires additional pipelines and equipment. Other additional pipelines and equipment are required, which increases the cost of using the oil storage tank group and reduces the utilization rate

Embodiment Construction
[0069] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and examples:
[0070] The present invention provides a multi-functional oil tank group device, such as figure 1 As shown, the apparatus includes a plurality of oil storage tank 1, main pipeline 22, bypass line 23, an external inlet branch 25, an external outlet branch 26, and a wireless control module 33. One end of each of the outlet branches 21 of each of the oil storage tank 1 is connected to the lowest point of the storage tank 1, and the other end is connected to the outlet branch direction selection valve 6; the outlet branch 21 of each oil storage tank 1, An outlet branch gate valve 2 and an outlet branch check valve 3 are sequentially provided after the lowest point of the oil storage tank 1. One end of the main pipe circuit 22 is connected to the outlet branch direction selection valve 6, and the other end is connected to the inlet branch di...

The invention discloses a multifunctional oil storage tank group device and a multifunctional realization method, mainly comprising a plurality of oil storage tanks, a main pipeline, a side pipeline, an external inlet branch, an external outlet branch, and a wireless control module. . It can realize the cleaning, transfer, external input and output, and self-inspection functions of the oil storage tank group. While ensuring the quality of the stored oil, it can improve the utilization rate of the oil storage tank, reduce the cost of use, reduce manpower input, and realize the automation of multiple functions. . In addition, the present invention also discloses a method for obtaining the working time / oil height meter, which calculates the time required for different heights and different sediments to move from the liquid surface to the bottom of the oil storage tank through the numerical calculation fluid dynamics method, so as to obtain the working time / oil height surface. The time required for the cleaning operation of a multifunctional oil storage tank device can be obtained by interpolating the working time / oil altimeter.
Description
Technical field [0001] The present invention relates to a multifunctional oil storage tank set device and a multi-functional implementation method, which belongs to the field of oil and gas reservoirs. Background technique [0002] Potted petrochemical oils may contain a variety of impurities, such as peeling internal anti-corrosion coating, oxide particles, heavy metal salts, paraffin, bacteria metabolites, and the like. These impurities belonging to the heavy components will gradually deposit into the bottom of the storage tank during the ordinary tank, and it will accumulate a layer of mud or flocculated precipitate in the bottom of the storage tank. This precipitate not only reduces the actual capacity of the storage tank, but also reduces the quality of the canture oil, it will block the oil pump, pipe valve, bleak, etc. Series issues. In order to eliminate problems caused by precipitates from petrified oil storage tanks, it is generally necessary to invest a large amount of...
