The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of device for recovering oil and gas of oil product storage tank, comprise several oil product storage tanks 1, oil product top in each oil product storage tank 1 is equipped with inner floating roof 2, at oil product storage tank 1 top, be provided with nitrogen inlet 3 and breathing valve 3, one vertical flexible pipe 5 upper ends that are located in oil product storage tank 1 are connected with nitrogen inlet 3, lower end overlaps mutually with inner floating roof 2, flexible pipe 5 can fluctuating and shrink or extend with inner floating roof 2, each oil product storage tank 1 top is connected with one end of a transportation pipeline 6 respectively, the other end of transportation pipeline 6 stretches into water sealed tank 7 bottoms straight down, on transportation pipeline 6, be provided with the first check valve 8, in the left upper portion of water sealed tank 7, be provided with a watering pipeline 9, right side central is provided with an overflow passage 10, bottom is provided with a delivery piping 11, at watering pipeline 9, on overflow passage 10 and delivery piping 11, be respectively equipped with a valve, the top of each water sealed tank 7 is connected with the one end on a manifold assembly road 13 by a concetrated pipe 12 respectively, the other end on manifold assembly road 13 is connected with the entrance of a cooling vessel 14, the admission port at one safe water sealed cans 15 tops is connected with manifold assembly road 13 by pipeline, the outlet of cooling vessel 14 is connected with the admission port on one point of flow container 16 top through pipeline, in the bottom of point flow container 16, be provided with one and be with valvular drain pipe 17, drain pipe 17 is connected with underground slop oil tank 21, divide the exhausr port at flow container 16 tops to be connected with compressor 18 entrances through pipeline, the by path that compressor 18 exports is connected with sulphur incinerator 22, another by path is successively through control cock 19, the second check valve 20 is connected with the admission port of point flow container 16.
Before use, the watering pipeline 9 of the sealed cans of fetching boiling water 7 and the valve of overflow passage 10, by watering pipeline 9, in the middle of water sealed tank 7, inject fresh water, when fresh water reaches certain liquid level, while there is overflow in overflow passage 10, close the valve of watering pipeline 9 and overflow passage 10, each water sealed tank 7 water filling work complete.Meanwhile, in the middle of safe water sealed cans 15, inject fresh water, reach certain liquid level and stop water filling later.Then, nitrogen inlet 3 is the space nitrogen injection to inner floating roof 2 tops by flexible pipe 5, air in the middle of inner floating roof 2 upper spaces is arrived in the middle of water sealed tank 7 through the first check valve 8 by the transportation pipeline 6 at oil product storage tank 1 top, and then startup compressor 18, the air of system pipeline the inside between each water sealed tank 7, cooling vessel 14 and point flow container 16 is extracted out, on the one hand guarantee that system pipeline is certain negative pressure, guaranteeing does not on the other hand have air in system pipeline.Now, whole regenerative apparatus is ready.
In oil product storage process, the oil gas producing in oil product can enter oil product storage tank 1 inside top space, when to the interior injection oil product of oil product storage tank 1, liquid level in it raises, inner floating roof 2 raises, oil gas in inner floating roof 2 upper spaces is by transportation pipeline 6, by the first check valve 8, be discharged in the middle of water sealed tank 7 again, oil gas upwards enters water sealed tank 7 inside top spaces from the bottom of water sealed tank 7 interior water, again through concetrated pipe 12, it is cooling that manifold assembly road 13 enters cooling vessel 14, and then enter in the middle of point flow container 16, the condensed fluid being cooled flows into separatory tank 16 bottoms, from bottom drain pipe 17, discharge, enter underground slop oil tank 21 to recycle, uncondensable waste gas enters compressor 18 entrances by the exhausr port at point flow container 16 tops through pipeline, through compressor 18 pressure-raisings, a gas part after pressure-raising enters sulphur incinerator 22, another part is by control cock 19, again by the second check valve 20, turn back to the admission port of point flow container 16, to regulate the pressure of point flow container 16.
When draining the oil, oil product storage tank 1 liquid level reduces, and nitrogen inlet 3 is supplemented nitrogen in inner floating roof 2 upper spaces of oil product storage tank 1, guarantees the equilibrium of pressure in oil product storage tank 1.
Destroyed when the negative pressure in system pipeline between each water sealed tank 7, cooling vessel 14 and point flow container 16, safe water sealed cans 15 play a role.When as excessive in the pressure in system pipeline, pressure can enter in safe water sealed cans 15, the water of safe water sealed cans 15 is extruded, to reduce the pressure in system pipeline; When as too small in the pressure in system pipeline, can in system pipeline, supplement nitrogen by safe water sealed cans 15, to increase the pressure in system pipeline, thereby guarantee in system pipeline that negative pressure is in certain limit value.
Under emergency episode state, while going wrong such as nitrogen system, water sealed tank 7, safe water sealed cans 15, compressor 18 etc., start the breathing valve 4 at oil product storage tank 1 top, to guarantee the equilibrium of pressure of oil product storage tank 1.
Adopt device for recovering oil and gas of the present utility model, reasonable in design, carries out recycling to the oil gas in oil product storage tank 1, both increase economic benefit, met again environmental demands, in addition, avoid oil product to contact with air, guaranteed the character such as oil product product look number, met requirements for quality.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
