Abstract

The invention discloses an oil-water separation device for a leakage drainage system in a hydropower station, which comprises a water pool, an oily water inlet pipe, a water discharging pipe and a floating ball alarm switch. The inner space of the water pool is sequentially divided into an oil-water separation groove, a cushion groove and a water discharging groove which are communicated internally by an upright first partition and a second partition, the oil-water separation groove divided by the first partition is communicated with the bottom part of the cushion groove, and the cushion groove divided by the second partition is communicated with the top part of the water discharging groove; the oily water inlet pipe is arranged in the upper part of the oil-water separation groove and is higher than the top end of the first partition, the water discharging pipe is arranged in the lower part of the water discharging groove, and the floating ball alarm switch is arranged in the oil-water separation groove. The device provided by the invention has strong oil separation capability and large capacity, totally relies on gravity without other machines or electric separation equipment in separation, has reliable working performance, and is free of maintenance, simple and practical.

Description

technical field [0001] The invention relates to an oil-water separation device, in particular to an oil-water separation device used in a seepage drainage system of a hydropower station. Background technique [0002] At present, most of the oil-water separation measures adopted in the drainage system of hydropower stations use a kind of mechanical and electrical equipment-oil-water separation device. [0003] The existing oil-water separation device is assembled into a whole by housing, primary filter, fine filter, electric plunger pump, screw pump, electric heater and various valves. The device uses a sewage pump to suck oily sewage, and then enters the primary filter. The oil droplets in the water float up to the oil collection chamber of the device after polymerization, and most of the oil is separated. After the primary filter, the water still contains tiny oil particles, and these sewage containing tiny oil particles are discharged into the fine filter chamber for coar...
