Problems solved by technology

Among them, the viscous oil collector mainly includes brush type and disc type, etc., which have high requirements on the type of oil and the thickness of the oil layer, and the recovery efficiency is low; Higher, the water in the recovered oil is large, and secondary separation is required; the dynamic slope type can adapt to various oils and general sea conditions, but it is more suitable for dynamic oil sweeping, not static oil recovery

Embodiment Construction

[0022] As shown in the drawings, the oil collection tank 1 is a closed container, the upper tank wall has an oil delivery port 7, the lower tank wall has a drain port 2, and the front tank wall opening is connected with the oil-water introduction channel 4, and the oil-water inlet A movable weir 5 and a baffle 8 are provided at the suction port of the channel 4, and the hydraulic cylinder 6 drives the movable weir 5 to move up and down, and a curved deflector 3 is provided below the oil-water inlet of the tank wall, and the buoyant tank 9 is connected with the oil collection tank 1 , providing buoyancy for the entire device.

[0023] The oil collection tank needs to be filled with water in advance before collecting oil. During operation, the drainage pump 11 discharges the water in the oil collection tank 1 through the drain port 2. In the oil tank 1, further, the curved deflector 3 guides the inhaled oil-water mixture to move upwards, and at the same time utilizes the specifi...

Abstract

An apparatus for recovering the oil floating on water surface is composed of oil deivering pump, water draining pump and oil collecting tank with oil-water inlet and curved guide plate. Its method includes filling water in oil collecting tank, putting it in the polltued water region, using water draining pump to discharge water from it while oil-water mixture flowing in it via said curved guide plate for separating oil layer from water layer, and pumping the oil to a storage position by oil pump.

Description

technical field [0001] The invention relates to a method and a device for recovering floating oil on the water surface. Background technique [0002] Water surface oil spill accidents, especially the occurrence of large-scale oil spill accidents, have caused serious pollution to the natural environment and directly endangered the living environment of human beings. At present, the main equipment for effective control of oil spills is the oil boom. Putting the oil boom and then using various oil recovery devices to try to remove it is the main measure taken when an oil spill occurs. The recovery methods are basically divided into sticky type, suction type and dynamic slope type. Among them, the viscous oil collector mainly includes brush type and disc type, etc., which have high requirements on the type of oil and the thickness of the oil layer, and the recovery efficiency is low; Higher, the water in the recovered oil is large, and secondary separation is required; the dyn...
