High-pressure water flow type separation device for multi-particle-diameter microplastics in deposits or soil

Abstract

The invention relates to a high-pressure water flow type separation device for multi-particle-diameter microplastics in deposits or soil. The separation device comprises a filter box and a waste liquid collecting box, wherein the waste liquid collecting box is arranged at the bottom of the filter box; the lower end of the filter box extends into the waste liquid collecting box; a plurality of mutually separated filter screens are arranged in the filter box; the filter box is formed by multistage framework units through splicing joint; a filter screen is arranged in the connecting position of the adjacent framework units; the framework unit comprises a vertical barrel wall; the two ends of the vertical barrel wall are respectively provided with an upper connecting part and a lower connecting part; the vertical barrel walls of the adjacent framework units are fast connected through the upper connecting part and the lower connecting part; a filter cavity is formed between the adjacent filter screens; a water inlet pipe is arranged on the top of the filter box; the end part of the water inlet pipe extends into the filter box; a plurality of vertical flushing mechanisms are arranged onthe water inlet pipe, are in one-to-one correspondence arrangement to the filter cavities and are arranged in the filter cavities. The flushing power is provided for high-pressure water; the driving by a motor is not needed; the whole achieves the environmental-friendly and energy saving effects.

Description

technical field [0001] The invention relates to environmental pollution monitoring and separation equipment, in particular to a high-pressure water flow type separation device for multi-particle diameter microplastics in sediment or soil. Background technique [0002] Microplastics (Microplastics) refer to plastic particles with a diameter of no more than 5 mm, which has become one of the hot issues of international concern. In 2014, the first United Nations Environment Assembly (UNEP1) listed microplastic pollution as one of the top ten global environmental problems to be solved for the first time. In 2015, UNEP2 listed marine microplastics as the second largest scientific issue in the field of environmental and ecological science research, and ranked it with global climate change, ozone depletion and ocean acidification as a major global environmental issue of common concern to scientists around the world.

AI Technical Summary

Problems solved by technology

Due to the late start of the detection of microplastic particle pollution, the collection equipment and collection methods are still lacking in accuracy and scientificity

The collection equipment is also relatively primitive and outdated. For example, the collection of microplastic particles in soil is a problem worthy of improvement. Now the separation of microplastics in soil is generally carried out on a single-stage filter, and there is no separation of microplastic particles of different particle sizes. Suitable devices for synchronous separation, resulting in low separation efficiency, and there is also the problem of incomplete separation of sediment and microplastic particles
