Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0026] As shown in the figure, the gravity coagulation oil-water separation device is generally arranged indoors. The device as a whole adopts the structure arrangement in the center according to the order of water flow. The main pool body is designed as a rectangle, which is welded by carbon steel and section steel, and the inner wall is treated with epoxy coal tar pitch paint for anticorrosion. Including impurity separation area 1, coagulation and flocculation area 2, water distribution area 3, oil-water separation area 4, water outlet area 5 and super high water level area.
[0027] The steel main tank body has a rectangular shape; the gravity coagulation oil-water separation device is characterized in that the impurity filtering device 6 is made of stainless steel with a filtration accuracy of 60 mesh.
[0028] In the gravity condensing oil-water s...

The invention discloses a gravitational coagulation type oil-water separation device including a pool body and an impurity separation zone, a coagulation flocculation zone, a water distribution zone, an oil-water separation zone and a water outlet zone which are successively distributed in the pool body; the impurity separation zone comprises an impurity filter device arranged in the pool body and capable of intercepting granular impurities in inlet water, and an impurity intercepting device can automatically eliminate the intercepted impurities; the coagulation flocculation zone is arranged after the impurity separation zone and is a dosing stirring mixing flocculation reaction zone, the mixing flocculation reaction zone is provided with an upper water outlet pipeline, the water distribution zone is arranged after the mixing flocculation reaction zone, and the water distribution device is provided with a flow stabilization device for making a water flow steadily enter the oil-water separation zone; collected floating oil is recycled through a floating oil collecting device; and effluent is qualified and is discharged or reused.
Description
technical field [0001] The invention relates to an oil-water separation device in the water treatment industry, and more specifically relates to a novel gravity device. Background technique [0002] my country is a country that is very short of water resources. With the development of the national economy, the shortage of water resources has restricted the development of industrial and agricultural production to a certain extent. Severe water shortage and aggravation of water pollution have become increasingly prominent environmental safety issues. It is a long-term strategic policy of my country's economic development to comprehensively promote the innovation of environmental science and technology, vigorously develop the comprehensive utilization technology of resources, effectively solve the environmental pollution in the rapid economic development, and realize water conservation and waste water resource utilization. At the same time, my country's oil and gas resources are...
