Description

Technical Field

[0001] The utility model relates to the technical field of inner floating plates, in particular to an inner floating plate capable of controlling VOCs emissions from a storage tank. Background Art

[0002] The self-floating assembled internal float is a floating roof that floats on the tank's liquid surface, rising and falling with the oil. Using this internal floating roof to cover the liquid surface is recognized as the ideal, most economical, and simplest method to reduce oil evaporation losses. It is suitable for docking tanks and lap tanks of various sizes. It does not contaminate oil or chemicals, but can reduce volatile losses of the medium and prevent air pollution. VOCs refer to volatile organic compounds, which have high saturated vapor pressure, low boiling point, small molecular weight, and are easily volatile at room temperature under standard conditions.

[0003] At present, most oils are stored and transported through storage tanks, which require internal floats. However, a large amount of volatile organic compounds (VOCs) will be generated during the storage process, which will lead to a decrease in oil quality and increase the company's operating costs. At the same time, some VOCs will leak into the surrounding air, causing a certain degree of air pollution. Utility Model Content

[0004] The purpose of the utility model is to provide an inner float that can control VOCs emissions from storage tanks, so as to solve the problem that some volatile organic compounds inside the storage tanks leak into the surrounding environment through the storage tanks, while reducing the generation of volatile organic compounds.

A second adsorption box 55 is provided on one side of the second treatment box 54. The VOCs gas treated by the second adsorption box 55 can be discharged through the outlet pipe 6.

[0026] refer to Figure 1 and Figure 2 As shown, the top of the second adsorption box 55 is connected to an outlet pipe 6. Under the action of the outlet pipe 6, the VOCs gas that has been processed multiple times can be collected and processed in a unified manner. The top of the first processing box 51 is connected to a first connecting pipe 7. Under the action of the first connecting pipe 7, the VOCs gas processed by the first processing box 51 can enter the interior of the first adsorption box 53 for adsorption treatment.

[0027] One end of the first connecting tube 7 away from the first processing box 51 is connected to the interior of the first adsorption box 53. The VOCs gas treated by the first processing box 51 enters the interior of the first adsorption box 53 through the first connecting tube 7 and can be adsorbed. The interior of the first adsorption box 53 is connected to the second connecting tube 8. The VOCs gas adsorbed by the first adsorption box 53 enters the interior of the second connecting tube 8, and then enters the interior of the second processing box 54 through the second connecting tube 8 for further treatment. The end of the second connecting tube 8 away from the first adsorption box 53 is connected to the interior of the second processing box 54.

[0028] The interior of the second processing box 54 is connected to the third connecting pipe 9. The VOCs gas processed by the second processing box 54 enters the interior of the second adsorption box 55 through the third connecting pipe 9, so that the VOCs gas can be adsorbed again. The end of the third connecting pipe 9 away from the second processing box 54 is connected to the second adsorption box 55.

[0029] The interiors of the first processing box 51 and the second processing box 54 are both connected by a regulating tube 10. Under the action of the regulating tube 10, it is convenient for the staff to replace and replenish the processing liquid inside the first processing box 51 and the second processing box 54. At the same time, a regulating valve is provided on the outside of the regulating tube 10, and a positioning plate 11 is provided on the inner wall of the second processing box 54. Under the action of the positioning plate 11, multiple regulating boxes and adsorption boxes can be tightly connected, which is convenient for the staff to disassemble and assemble them.

[0030] refer to Figure 3 As shown, a first filter plate 12 and a second filter plate 13 are fixedly connected to one side of the inner wall of the second adsorption box 55. Under the action of the first filter plate 12 and the second filter plate 13, the VOCs gas adsorbed by the second adsorption box 55 can be released and then uniformly collected and processed through the outlet pipe 6. A placement groove 14 is provided inside the second adsorption box 55, and a connecting plate 15 is fixedly connected to the bottom of the support plate 2.

[0031] refer to Figure 4 As shown, an adjusting airbag 16 is provided at the bottom of the inner floating plate body 1. Under the action of the adjusting airbag 16, the staff can control the expansion degree of the adjusting airbag 16 to seal the inner floating plate body 1 with the inner wall of the tank. The top of the adjusting airbag 16 is respectively connected to a top pipe 17 and a discharge pipe 18. Under the action of the top pipe 17 and the discharge pipe 18, it is convenient for the staff to release and replenish the gas inside the adjusting airbag 16.

[0032] The interior of the regulating airbag 16 is connected to a connecting airbag 19. Under the action of the connecting airbag 19 and the regulating airbag 16, the inner floating plate body 1 can withstand a larger buoyancy, thereby enabling the inner floating plate body 1 to work normally. The top of the connecting airbag 19 is fixedly connected to a connecting frame 20.

[0033] Working principle: When the staff uses the inner float body 1 normally, a certain amount of VOCs gas will be generated inside the storage tank. First, the VOCs gas enters the interior of the first processing box 51 through the air inlet pipe 52. The interiors of the first processing box 51 and the second processing box 54 both contain processing liquid. The gas enters the interior of the first processing box 51 and is processed under the action of the processing liquid. The treated gas enters the interior of the first adsorption box 53 through the first connecting pipe 7. Under the action of the adsorption material inside the first adsorption box 53, the treated gas can be adsorbed. Then, it enters the interior of another second processing box 54 again through the second connecting pipe 8 and is processed again. Each time the processing box is processed, the adsorption box will be adsorbed, and then the gas will enter the interior of the second adsorption box 55. Then, it is uniformly collected and processed again through the air outlet pipe 6, so that the VOCs gas concentration inside the storage tank can be controlled. At the same time, under the action of the regulating airbag 16 and the connecting airbag 19, the inner float body 1 can be kept in contact with the oil inside the storage tank at all times, which can reduce the generation of VOCs gas to a certain extent.
