A kind of internal rotation magnetic self-diffusion aggregation type wastewater oil pollution adsorption column

Abstract

The invention discloses an internally rotating magnetic self-diffusion and aggregation type wastewater oil pollution adsorption column, which belongs to the technical field of wastewater oil pollution treatment. In the initial state of the invention, the fixed magnetic column and the moving magnetic column are in the opposite state of the same pole. There is a mutual repulsive force between them, so that multiple devices will automatically move away from each other in the wastewater to achieve self-diffusion, and they will be distributed on the surface of the wastewater to the greatest extent to achieve sufficient and efficient absorption of oil on the water surface; and with the oil absorption of the oil-absorbing rubber column The expansion drives the puncturing needle to puncture the water bladder, the water is lost, and the water bladder deflates. Due to the mutual repulsion between the fixed magnetic column and the moving magnetic column, the moving magnetic column rotates 180° around the fixed rod until the moving magnetic column and the fixed magnetic column are different. The poles are relatively attracted to each other. At this time, the ends away from each other are different poles, so that there is an attractive force between the multiple devices after oil absorption, and they are close to each other to realize the self-aggregation process, which is convenient for targeted and rapid Salvage collection.

Description

technical field [0001] The invention relates to the technical field of waste water oil pollution treatment, and more specifically relates to an inner-rotation magnetic self-diffusion aggregation type waste water oil pollution adsorption column. Background technique [0002] Oily wastewater comes from a wide variety of sources. In addition to a large amount of oily wastewater discharged from oil extraction and processing industries, there are solid fuel thermal processing, wool washing wastewater in the textile industry, tanning wastewater in light industry, railway and transportation industries, slaughtering and food processing, and turning processes in the machinery industry. Among them, the oily wastewater discharged from the petroleum industry and solid fuel thermal processing industry is the main source. [0003] At present, there are many methods for treating oil pollution in industrial and domestic wastewater, such as mechanical recovery, adsorption, chemical dispersi...

Problems solved by technology

[0004] However, when using the adsorption method to treat waste water, because a large amount of adsorption particles need to be put in, firstly, it is difficult to disperse a large number of adsorption particles evenly on the surface of the wastewater; , it is easy to have a large number of adsorption particles that are salvaged before reaching adsorption saturation, making the utilization rate of adsorption particles low
