Embodiment Construction
[0022] The technical solutions and technical effects of the present invention will be further described in detail below in conjunction with the accompanying drawings of the present invention.
[0023] Please see figure 1 , in a specific embodiment, a transformer accident pool oil-water separation device 10, used to realize the oil-water separation of transformer accident pool sewage in the non-inspection and maintenance state, or realize the oil-water separation of transformer accident pool sewage after preliminary separation under the maintenance state separate. The oil-water separation device 10 of the transformer accident pool includes an oil-water aeration tank 100 and an oil-water separation pipe 200. The bottom of the oil-water aeration tank 100 is provided with an aeration pipe 110 and a water supply pipe 120, and the upper part is provided with an oil-water overflow pipe 300. . The oil-water separation pipe 200 is provided with an oil-water feed port, and the oil-wat...

Abstract
The invention provides an oil-water separation device for a transformer accident pool oil-water separation device. The device comprises an oil-water aeration tank and an oil-water separation pipe, thebottom of the oil-water aeration tank is provided with an aeration pipe and a water supplementing pipe, the upper part of the oil-water aeration tank is provided with an oil-water overflow pipe, theoil-water separation pipe is provided with an oil-water feed port, and the oil-water feed port is connected with the oil-water overflow pipe. When the oil-water separation operation is carried out onthe sewage of the transformer accident pool, the sewage firstly enters the oil-water aeration tank, and the liquid level is controlled to reach the inlet of the oil-water overflow pipe. On one hand, oil and water are separated through aeration, and the oil content in a water phase is reduced; on the other hand, the liquid level in the oil-water aeration tank fluctuates through aeration, and transformer oil floating on the liquid level and part of water enter the oil-water separation pipe through the oil-water overflow pipe. And after a period of time, standing is performed to layer oil and water in the oil-water separation pipe. After standing and layering, the water phase at the bottom layer can return to the oil-water aeration tank for secondary aeration, so that the treatment depth is increased. And an oil phase is discharged, so that the water quantity in the oil phase is greatly reduced, and real oil-water separation is realized.
Description
technical field [0001] The invention belongs to the technical field of substation safe operation, and in particular relates to an oil-water separation device for a transformer accident pool. Background technique [0002] According to GB50060-2008 "3-110kV high-voltage power distribution equipment related specifications", when the oil volume of a single outdoor electrical equipment is more than 1000kg, oil storage or oil retaining facilities should be installed. It is specifically pointed out that facilities for draining oil to safe places should be provided, and if the requirements cannot be met, oil storage or oil retaining facilities that can accommodate 100% of the oil volume should be provided. [0003] Due to the open-air setting of the transformer accident oil pool, rainwater can enter and accumulate in the accident oil pool. Under normal circumstances, the rainwater evaporates naturally and does not affect the normal function of the accident pool. In two cases, it is...
