The safety standard of the nuclear power station is high, the environmental protection requirement is strict, the current environmental protection proposes that the whole factory accident oil discharge needs to be stored in a sealed oil storage tank and cannot be discharged, and then unified treatment is carried out in the factory so as to prevent the pollution problem caused by the oily wastewater of the nuclear power station. Therefore, the problems of water inlet energy dissipation, storage and preliminary oil-water separation of accident oil and water in the nuclear power station are solved, the inner volume of the oil storage tank is ensured not to be occupied by rainwater, and the like, and the method has very important long-term significance.
According to fire control standard requirements, when the transformer catches fire in an accident, the effective volume of the accident oil pool needs to be considered according to 100% of accident oil quantity of the maximum transformer. For large nuclear power plants, such as 1000MW nuclear power units in coastal areas, the maximum oil accident amount of one transformer is about 68m 3. In addition, according to the fire control design requirement, the corresponding transformer water spray design fire control water quantity is about 720m 3, and the outdoor hydrant water quantity is 108m 3.
The accident oil storage tank of present design, in order to make accident oil storage tank satisfy the requirement of oil storage volume, accident oil storage tank bottom is darker, but the inlet tube is the horizontal access accident oil storage tank, and the pipe is low to be greater than 3m apart from accident oil storage tank bottom height generally, and when the water level in the accident oil storage tank was lower, drop height was great, had great washing away to the pond bottom.
Disclosure of utility model
In order to solve the technical problems that in the background technology, the volume of an oil storage tank is large, the bottom is deep, and the bottom of the oil storage tank is too much washed by a water inlet pipe, the utility model aims to provide a novel oil storage tank, and the problems can be solved.
The technical scheme for realizing the aim of the utility model is as follows: the utility model provides a novel oil storage pond, includes the inlet tube, the inlet tube intercommunication the oil storage pond and distance oil storage bottom of the pool portion has the settlement height, the delivery port setting of inlet tube is in the bottom of oil storage pond, and the opening up for reduce the liquid follow the washing away to the oil storage bottom of the pool after the inlet tube flows.
When oily wastewater needs to be discharged into the oil storage tank through the water inlet pipe, the water inlet pipe stretches into the oil storage tank from the side wall of the oil storage tank, a certain height distance is reserved between the water inlet pipe and the bottom of the oil storage tank, and if the oily wastewater is directly discharged into the oil storage tank from a higher height, the bottom of the oil storage tank is easy to wash. The water outlet of the water inlet pipe is arranged at the bottom of the oil storage tank, and the opening of the water inlet pipe faces upwards. The water outlet of the water inlet pipe is arranged at the bottom of the oil storage tank, and the oily wastewater is not directly poured out from the water outlet from a high place, so that the bottom of the oil storage tank is not flushed; the water outlet opening is upward and is not directly opposite to the bottom of the oil storage tank, so that the condition that the bottom of the oil storage tank is not flushed by oil-containing wastewater is further ensured.
Further, the water inlet pipe is provided with a bending part, and the bending part is positioned at the water inlet of the water inlet pipe. The water inlet of the water inlet pipe is designed into a bent shape, so that direct impact of the oily wastewater can be blocked through the bent part of the water inlet pipe, and the kinetic energy of the oily wastewater is reduced and lowered.
Further, the pipe diameter of the water inlet pipe is reduced from the water inlet to the water outlet, and the flow of the oily wastewater can be reduced by reducing the pipe diameter of the water inlet pipe, so that the impact potential energy of the oily wastewater is further reduced.
Further, the water pipe also comprises an overflow weir, wherein the overflow weir is arranged at one side of the water outlet of the water pipe, which is far away from the water inlet. The oily wastewater discharged from the water inlet pipe is spread into the oil storage tank through the overflow weir, so that the flow velocity of the oily wastewater is reduced, and the flushing problem of the oily wastewater to the bottom of the oil storage tank is further reduced.

The water level can be monitored by means of the liquid level meter, and clean water can be injected into the oil storage tank if the water level is lower than the height of the water passing hole, so that the water level is always higher than the height of the water passing hole.
Further, an overflow pipe is arranged in the water outlet well, and the height of the overflow pipe is higher than the height of the highest position of the water inlet pipe. When accident fire control happens, a large amount of oily wastewater can be accumulated in the oil storage tank, and redundant fire water exceeding the design requirement in the oil storage tank can be discharged by means of the overflow pipe. Because the dirty oil floats on the water surface and is isolated outside the water outlet well by the water passing holes, the water in the water outlet well is cleaner and can be discharged into a rainwater pipe network of a factory, and meanwhile, the height of the overflow pipe is higher than that of the water inlet pipe, the rainwater pipe network of the factory is not required to have very low height when the water is discharged to the rainwater pipe network in a self-flowing mode, namely, the sewage pipe network of the whole factory is not required to be buried too deeply, so that the investment cost of the rainwater pipe network of the factory can be reduced, and the cost is reduced.
Further, a valve is arranged on the overflow pipe and used for controlling the discharge water of the overflow pipe. When the overflow pipe is idle and not used, the overflow pipe is closed for a long time, backflow is prevented, and when the overflow pipe is used, the overflow pipe is opened.
Further, an oil collecting groove and an oil collecting well are arranged in the oil storage tank, and the oil collecting groove is communicated with the oil collecting well and used for collecting and discharging dirty oil in the oil storage tank. When the oily wastewater is accumulated in the oil storage pool, dirty oil floats on the water surface, the dirty oil is concentrated into the oil collecting well by the oil collecting groove, and the dirty oil is pumped away by the oil pump for other use.
