Embodiment 1
[0028] see Figure 1~4 , a heat recovery device for oil in an internal floating roof storage tank, comprising an internal floating roof storage tank 1, a buffer tank 2, a heating furnace 3 and an evaporation tank 4, the oil and gas collection pipe 5 of the internal floating roof storage tank 1 is connected to the The buffer tank 2 communicates, the buffer tank 2 communicates with the first air pump 6, the exhaust port of the buffer tank 2 communicates with the air inlet 22 of the heating furnace 3, and the heating furnace 3 is arranged in the evaporation tank 4, The evaporation tank 4 is provided with a number of diffusion barrier rings 7 surrounding the heating furnace 3, and the diffusion barrier ring 7 divides the evaporation tank 4 into several independent water storage chambers 8. The diffusion barrier ring 7 Comprising a metal ring 9, a spiral tube 10 and a vertical tube 11, the two sides of the metal ring 9 are respectively provided with the spiral tube 10 and the verti...
Embodiment 2
[0036] see Figure 5 The difference between this embodiment and Embodiment 1 is that the spiral pipe 10 and the vertical pipe 11 are embedded in the metal ring 9, the vertical pipe 11 is provided with a first one-way valve 32, and the water storage A cover 33 is slidingly provided in the chamber 8, and the cover 33 is provided with a sealing gasket 34 in contact with the inner wall of the diffusion barrier ring 7, and the cover 33 is connected to the top of the evaporation tank 4 through an electric telescopic rod 35 , the cover 33 is provided with a second one-way valve 36 . The inner and outer walls of the diffusion barrier ring 7 are smooth, and the cover 33 sliding in the water storage chamber 8 is in sealing contact with the inner wall of the diffusion barrier ring 7 . The cover 33 is connected to the top of the evaporation tank 4 through an electric telescopic rod 35. When the electric telescopic rod 35 is extended, the liquid surface is pressed down. The vertical pipe ...
