Embodiment Construction
[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] image 3 It is a structural schematic diagram of the first embodiment of the filter adsorption unit in the present invention. Such as image 3 As shown, the filter adsorption frame 2 is a U-shaped frame with an upper opening, and a plurality of slots are provided inside the frame for inserting the oil filter screen 4 and the adsorption layer 5; the oil filter screen 4 and the adsorption layer 5 are both nets. Shaped plug-in type, which can be quickly installed or replaced and disassembled, and is made of polypropylene or other corrosion-resistant materials.
[0037] image 3 The filter adsorption frame 2 shown has five slots, in which two oil filter screens and three adsorption layers are inserted, but the number of slots of the filter adsorption frame can also be designed and flexibly determined according to the actual need...

The invention provides a water area dirt-removing interception and absorption dam and assembly component thereof, which comprises a filtering and absorbing unit including a filtering and absorbing frame and an oil filtering net and an absorbing layer which are arranged on the filtering and absorbing frame, wherein the filtering and absorbing frame is a U-shaped frame and a plurality of slots are arranged inside the frame; the oil filtering net and the absorbing layer are of net-like board-inserting type, and are inserted in the slots of the filtering and absorbing frame in turn. In addition, the invention provides a water area oil-removing unit and an interception and adsorption assembly component thereof as well as an interception and adsorption dam which is composed of arrange connections of interception and adsorption assembly components. The assembled cell structure according to the invention can intercept oil, adsorb and filter chemical contaminants in water, be easy for assembly and disassembly, quickly replace the excessive consumption of filtration and adsorption devices in the dirt-removing equipment, and respond to different river water pollution incidents by combined assembly of emergency operations.
Description
technical field [0001] The invention relates to the technical field of decontamination in river waters, in particular to a water decontamination interception adsorption dam and its assembled components, which have the functions of oil confinement, oil collection and filtration and adsorption. Background technique [0002] When ship oil spill accidents and chemical dangerous goods leakage occur in coastal waters, inland rivers, ports and other waters, a large amount of crude oil and diesel oil spilled on the water surface will form oil slick pollution and chemical pollutants that seriously damage the environment. Emergency control is required, oil pollution is recovered and chemical pollution is removed by adsorption things. [0003] The difference in specific gravity is used to remove the oil slick on the water surface with a vacuum pump. This method can quickly remove a large area of oil slick on the water surface and improve the oil removal effect, but it cannot solve th...
