Description
Technical field
The utility model belongs to transformer substation assisted devices field, more particularly to a kind of substation's overflow-type emergency oil pond.
Background technology
According to《35 ~ 110KV substations ' design specifications》、《Thermal power plant and Substation Design fire safety rules》Requirement,
When the oil mass of the single fuel tank of main transformer is in 1000KG and the above, oil-stored hole and emergency oil pond, each transformation should be set at the same time
Oil-stored hole corresponding to device is connected by oil exit pipe with emergency oil pond.Accident of Transformer oil extraction due to fire-fighting and environmental protection requirement not
It can be directly discharged into sewer pipe network.In the prior art, Design of Transformer accident oil extraction, is to design one to have into without the accident oil haveing
Pond.Annual rainy season rainwater is cheated to emergency oil pond connecting tube by transformer oil storage enters emergency oil pond.When the rain in emergency oil pond
It will cause oil-stored hole ponding after water product is full, the ponding in oil-stored hole can cause water to permeate the ground workshop.In order to ensure transformer
Accident oil extraction, the staff of substation need to rain every time after to emergency oil pond pumping drainage and artificial drainage, workload is very
Greatly, wasting manpower and material resources, are unfavorable for substation's normal operation.And the rainwater in emergency oil pond contains oil, directly discharge can also make
Into environmental pollution.Oil is mainly oil slick in rainwater in emergency oil pond, can be swum on the water surface, using water, oily proportion not
With the separation that can complete water, oil.In practical applications, when there is accident oil extraction, occur in emergency oil pond substantial amounts of
The mixture of oil and water, by the initial gross separation of oil and water, can exhaust a part of water, in order to ensure that the water of oil-containing will not discharge
And environment is polluted, a part of water is still had in emergency oil pond, this will influence recycling oily in emergency oil pond.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of substation's overflow-type emergency oil pond, can be effective
Water oil in emergency oil pond is separated, oil will not be discharged in environment, and a part of oil can be kept completely separate out
To be recycled.
In order to solve the above technical problems, technical solution is used by the utility model:A kind of substation's overflow-type accident
Oil sump, including oil sump, the oil sump upper end set inlet port and snorkel, set first partition in the oil sump, and described first
Oil sump is separated into the oil storage pool and separate tank of top connection by partition plate, and the height of first partition is less than the height of oil sump, oil inlet pipe
It is connected with separate tank, separate tank side sets the first drainpipe, and the top of first drainpipe is less than the height of first partition
Degree, the oil storage pool set oil discharge outlet, and oil discharge outlet sets valve.
In preferable scheme, the bottom nozzle of first drainpipe is extended to above separate tank bottom.
In preferable scheme, second partition is set, and oil sump is separated into by first partition and second partition in the oil sump
Oil storage pool, separate tank and blowoff basin, second partition separate separate tank and blowoff basin, and second partition top sets venthole, row
Pond side sets the second drainpipe.
In further scheme, first drainpipe be inverted " U " type structure, be less than at the top of the first drainpipe first every
The height of plate, the water inlet end and discharge ends of the first drainpipe are respectively positioned at the bottom of separate tank and blowoff basin top.
In further scheme, the bottom nozzle of second drainpipe is extended to above blowoff basin bottom.
In further scheme, the blowoff basin bottom sets open caisson, and the bottom nozzle of the second drainpipe is arranged on open caisson
Top.
In preferable scheme, EPS fillers are set in the separate tank.
A kind of substation's overflow-type emergency oil pond provided by the utility model, by setting first partition to be divided into oil sump
Top connection oil storage pool and separate tank, when simply oil-containing rainwater enters oil sump, by being stood in separate tank, realize water,
Oil separation, when liquid level is higher than drainpipe top in separate tank, the water of lower floor is discharged from drainpipe；When the large-scale accident of appearance
During oil extraction, the oil of discharge enters separate tank by oil inlet pipe, and when liquid level is higher than drainpipe top in separate tank, the water of lower floor is from row
Water pipe is discharged, and as the rising of liquid level in separate tank, the oil on upper strata overflow into oil storage pool above first partition, oil storage pool
In be substantially free of water oil, can recycle.In preferable scheme, oil sump is separated into oil storage pool, separate tank and blowoff basin,
Blowoff basin can carry out second to water therein, oil and separate, and make oil, water separating effect more preferable.The EPS fillers of setting, make to contain
When oily rainwater is by equipped with EPS fillers, elaioleucite changes from small to big, so as to be easier to realize water-oil separating.
