Oil water separator

Abstract

An oil water separator comprises an oil water separation tank, a filter which is arranged inside the oil water separation tank, an overflow storage tank which is arranged on the oil water separation tank, a drain tube which is connected with the overflow storage tank and an overflow device which is arranged on the overflow storage tank. The oil water separator is characterized in that: the overflow device is composed of a permanent flow overflow tube and an adjusting overflow tube, lower ends of the permanent flow overflow tube and the adjusting overflow tube which are hermetically penetratedinto the overflow storage tank are close to the bottom of the oil water separation tank, the side wall of the upper end of the adjusting overflow tube which is positioned inside the overflow storage tank is provided with a through hole, the upper end of the adjusting overflow tube which is positioned inside the overflow storage tank is provided with a floating stopper, and the cross section of the stopper is matched with the cross section of the upper end of the adjusting overflow tube positioned inside the overflow storage tank. Compared with the prior art, the oil water separator has the advantages of simple structure, low operating cost and high oil water separation rate.

Description

Technical field: [0001] The invention relates to a separator, especially an oil-water separator. Background technique: [0002] The working principle of the existing oil-water separator is to separate the oil from the water to the water surface by standing still, and the water sinks to the bottom of the oil layer, and then extract the water and oil respectively to complete the oil-water separation, and the oil-water separation The key is to allow enough rest time. The existing technology is to prolong the standing time of oil and water through multiple multi-stage separation cycles, and at the same time achieve the purpose of continuous oil and water separation. However, this method requires an electric transmission device to work, which consumes a lot of energy and has a complicated structure, and the separation cost is high; some technologies continuously put water into a separation box, and pass through a tube that reaches the bottom of the water. The oil-separated wate...

Problems solved by technology

However, this method requires an electric transmission device to work, which consumes a lot of energy and has a complicated structure, and the separation cost is high; some technologies continuously put water into a separation box, and pass through a tube that reaches the bottom of the water. The oil-separated water overflows into the small water tank above the tank and then discharged. This technology is very good for the separation of oil-water with a stable flow rate flowing into the separation tank. Moreover, the structure of the device is simple and the cost of use is low. However, the flow rate of oil and water in the actual separation process is unstable, and the amount of water that overflows the pipe into the small water tank above the tank is also unstable. The combination of the two unstable factors will easily cause the oil and water in the water tank to collide. Flow occurs, which destroys the separation of oil and water in the separation box, so a high oil-water separation rate cannot be guaranteed, and the maximum is no more than 80%.
