Connecting rod fluctuation type adsorption device applied to sudden water contamination emergency treatment

Abstract

The invention provides a connecting rod fluctuation type adsorption device applied to sudden water contamination emergency treatment. A rocker transmission device is fixed on a water floating device and fixedly connected with the top ends of connecting rods, so that the connecting rods can be fluctuate up and down by driving the rocker device; granular adsorption materials are filled in a rectangular filter bag in a half filling state; and four corners of the filter bag are respectively fixed on four connecting rods through coupler locks. According to the connecting rod fluctuation type adsorption device, convective diffusion is strengthened by fluctuating and oscillating the adsorption materials in the filter bag, so that the adsorption materials in the filter bag are fluidized to a certain extent, and a remarkably contamination removing effect can be achieved. When the device is used for removing organic matters or toxic and hazard matters such as heavy metal out of a water body, the contact opportunity of the adsorption materials in the filter bag and organic matter or toxic and hazard matters such as heavy metal can be greatly increased, the adsorption area of the whole device in water can be increased, and the content of organic matter or toxic and hazard matters such as heavy metal in the water body can be reduced in a short period.

Description

technical field [0001] The invention relates to a connecting rod undulating adsorption device used in emergency treatment of sudden water pollution, belonging to the technical field of adsorption devices. Background technique [0002] In recent years, sudden water pollution incidents have occurred frequently in my country, causing serious environmental hazards. It is different from general water pollution. Sudden water pollution incidents are extremely unpredictable and diverse, and will occur in a short period of time. A large amount of pollutants are leaked and discharged, which is seriously harmful and difficult to deal with. [0003] There are many research reports on the treatment of water pollution accidents caused by toxic and harmful substances such as sudden organic substances or heavy metals, but the treatment technologies that can be practically applied in natural water body sudden pollution incidents are very limited, and the treatment effect, application cost and...

[0002] In recent years, sudden water pollution incidents have occurred frequently in my country, causing serious environmental hazards. It is different from general water pollution. Sudden water pollution incidents are extremely unpredictable and diverse, and will occur in a short period of time. Causes a large amount of pollutants to leak and discharge, which is seriously harmful and difficult to deal with

[0003] There are many research reports on the treatment of water pollution accidents caused by toxic and harmful substances such as sudden organic substances or heavy metals, but the treatment technologies that can be practically applied in natural water body sudden pollution incidents are very limited, and the treatment effect, application cost and follow-up There are still many problems with the impact of

Adsorption is one of the main methods to remove pollutants, and it has been successfully applied in some emergency treatment. Its biggest advantage is the ability to quickly remove pollutants from the water phase. The limitation is that it needs to be packed in bags to remove them from the water. Recycling in water directly leads to an increase in fluid resistance and a decrease in mass transfer efficiency

[0004] Chinese patent document CN101838026 discloses an "Adsorption Dam for Emergency Treatment of Sudden Heavy Metal Pollution in Natural Water Bodies". This kind of emergency treatment adsorption dam adopts modular combination and double-layer filtration and adsorption. Although the processing capacity is large, it has a small flow capacity. And the construction is more difficult

Chinese patent document CN 101531405 discloses a "mobile adsorption process and device for toxic and harmful substances in natural waters". In the process of moving, tight accumulation will be formed, which will seriously affect the effect of adsorption and mass transfer, and the effect of convection and diffusion will be very limited.
