Description
Technical field
The utility model relates to a kind of cleaning equipment, particularly relates to a kind of petrochemical industry storage tank high-concentration organic waste gas UV photodissociation cleaning equipment.
Background technology
In the storage of petrochemical industry storage tank, in storage tank, oil product evaporating loss is that the steam produced because the change of temperature and atmospheric pressure causes the expansion of steam and contraction is discharged, and it appears at the situation that tank level is not any change, and is the natural discharging modes of non-artificial disturbance.In petroleum storage process, owing to being subject to the restriction of technology and equipment, inevitably some lighter liquid composition vaporization, escape into air, cause expendable loss, this phenomenon is called the evaporating loss of oil product.In normal conditions, the loss produced when the big breathing loss when evaporating loss in actual storage and transport process is mainly divided into the breathing loss of oil tank, oil transferring, oil tank gravity-flow ventilation loss, empty oil tank charge of oil.Tank area evaporating loss is mainly derived from " Big and Small Breath " of oil tank.
1. storage tank " little breathing " loss: when referring to that storage tank does not carry out oil transferring, oil product is static to be stored in tank, and product vapour is full of reservoir gas space, due to the evaporating loss that the day-night change of gas compartment temperature in tank causes.
2. loss " breathed greatly " by storage tank: refer to that liquid level constantly rises when storage tank receiving liquid coating layer, in-tank mixing gas is made pressure constantly raise by compressing, when gas compartment pressure is greater than the controlling value of pressure valve, pressure valve is opened, and outside mist overflows and fills with, thus produces evaporating loss.
According to nineteen ninety-five international petroleum meeting coverage, U.S.'s oil product evaporating loss amount accounts for 3% of crude output.The investigation of owned enterprise of petro chemical industry portion of the former Soviet Union in 1975 shows, oil product evaporating loss amount accounts for 2.47% of crude output, wherein 70% evaporating loss betiding petroleum tank, Mixer pot and product tank.Within 1980, the test result of China to 11 oil plays shows, Loss of Oil Evaporation amount accounts for 2% of crude output.China's oil year, loss amount was 4,000,000 tons, and more than 80% from the volatile emission in accumulating.These data show, worldwide Loss of Oil Evaporation problem is very outstanding, the oil product considerable amount of annual evaporating loss, not only cause a large amount of economic losses, energy loss, also contaminated environment, increase the probability that secondary environment risk occurs.In petrochemical industry storage tank, oil product evaporating loss problem is very outstanding as can be seen here; quantitative estimation is carried out to its discharge capacity; determine its atmosphere environment impact; and according to petroleum chemical enterprise's concrete condition; in conjunction with overall control index and residing regional environment present situation; propose realistic plan targetedly, environmental protection work could be fulfilled.The object of this patent is that the waste gas produced for oil product evaporating loss in petrochemical industry storage tank provides processing method and equipment.
