Example Embodiment

[0040] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] In the first aspect, an embodiment of the present invention provides a floating oil suction device in an oil storage tank, as shown in the attached figure 1 As shown, the suction device includes: a positioning plate 1, a first oil suction pipe 2, a second oil suction pipe 3, an upper floating plate 4, and a lower floating plate 5. Among them, the first oil suction pipe 2 passes through and is fixed on the positioning plate 1; the upper end of the second oil suction pipe 3 is vertically connected to one end of the first oil suction pipe 2; the upper floating plate 4 is connected to the second oil suction pipe through the liquid hole provided on the plate surface. The lower end of the oil suction pipe 3 is vertically connected; the lower ...

Abstract

The invention discloses a suction device and method for oil spill in an oil storage tank, and belongs to the field of oil and gas storage and transportation. The suction device comprises a positioningplate, a first oil suction tube, a second oil suction tube, an upper floating plate and a lower floating plate, wherein the first oil suction tube penetrates through the positioning plate and is fixed on the positioning plate; the upper end of the second oil suction tube perpendicularly communicates with one end of the first oil suction tube; the upper floating plate perpendicularly communicateswith the lower end of the second oil suction tube through a liquid hole formed in the plate surface; the lower floating plate is connected with the upper floating plate through a connector; and a gapwith adjustable length is formed between the top of the lower floating plate and the bottom of the upper floating plate. It ensures that the sucked oil is oil spill instead of a mixed solution of theoil spill and sewage. The oil suction effect can be ensured, furthermore, air in the oil storage tank is prevented from being sucked, and the oil spill suction effect is improved. Visibly, the deviceprovided by the embodiment of the invention can recycle the oil spill in the oil storage tank to reuse the oil spill, and meanwhile, potential safety hazards caused when people enter the oil storage tank for cleaning operation are solved.

Description

technical field [0001] The invention relates to the field of oil and gas storage and transportation, in particular to an oil floating oil suction device and method in an oil storage tank. Background technique [0002] The oil storage tank is a container for storing oil products. During the application process, a part of sediment will inevitably accumulate at the bottom of the oil storage tank, which will affect the tank capacity. The sediment mainly includes heavy components in the stored oil products (such as wax , colloid, asphaltene and other organic matter, accounting for about 95% of the total sediment) and solid impurities (such as sediment, rust residue and other inorganic matter). Therefore, in order to restore the tank capacity and meet the requirements of normal use and maintenance of the oil storage tank, it is necessary to clean the oil storage tank. [0003] The prior art adopts mechanical means to clean the oil storage tank to remove sediment, so that the oil ...
