Description

Multi-chamber reciprocating marine microplastics synchronous collection and separation device with sand removal fan

technical field

The utility model relates to environmental pollution monitoring and separation equipment, in particular to a multi-chamber reciprocating synchronous collection and separation device for marine microplastics with sand removal fans.

Background technique

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.

Microplastics in water mainly come from the use of products containing microplastic particles by human beings, causing microplastics to enter the environment and large pieces of plastic waste to decompose or break into tiny particles and enter the environment. Among them, the plastic microbeads (Microbeads) added in personal care products are one of the direct environmental sources of microplastics in water bodies. In some personal care products such as body wash, facial cleanser, toothpaste, and some cosmetics such as eye shadow, mascara, moisturizer, etc., plastic microbeads mainly made of polyethylene and polypropylene are artificially added during the production process. After personal washing, the plastic microbeads in the wastewater enter the sewage plant through the sewer. Due to the small size, light density, and large quantity of plastic microbeads, it is difficult to effectively remove these plastic microbeads with the current conventional treatment process in sewage plants, and most of them will enter natural water bodies, and eventually flow into the ocean and exist for a long time. Potential hazards to freshwater and marine ecosystems and even human health through the food chain. Large pieces of plastic waste will also produce a large number of plastic particles during the degradation process. These plastic particles enter rivers, lakes and seas through garbage, soil and surface water circulation, causing microplastic pollution. Due to the above situation, it is necessary to study the form and concentration of microplastics in water bodies. We need to collect samples of microplastics in water bodies and detect the content of microplastics according to needs, so as to contribute to the protection of the ecological environment of water bodies and the control of microplastic pollution. Provide test data. 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 water bodies is a problem worthy of improvement.

At present, the collection of microplastic samples in marine water is generally realized by using a simple mesh bag. This kind of mesh bag needs a certain aperture and is placed in the direction of water flow to collect microplastic particles in enriched water. According to the size of microplastic particles To determine the amount of microplastics in water bodies. However, this mesh bag is a single mesh bag with a fixed aperture, just like a plankton trap device, which can only collect all particulate matter with a particle size larger than the aperture of the mesh bag, and cannot classify and screen the particulate matter, so it cannot be detected in time The content of microplastic particles of different particle sizes in the effluent. It is also not conducive to scientific evaluation of the degree of microplastic pollution in water bodies. Sometimes microplastic particles collected using the simple mesh bags described above need to be further separated to analyze the content of different microplastic particles. Because the microplastic particles obtained by this method are still a combination of microplastic particles of many particle sizes, further separation is required. Separation is generally carried out by adding water to a single-stage filter. Every time a range of particle sizes is separated, the One-time separation operation, there is no suitable device for synchronous separation when separating microplastic particles of different particle sizes, resulting in low separation efficiency, and sand particles in seawater are likely to be mixed in microplastics during the collection and separation of microplastics The problem.

When the device is put into use, the microplastic collection box 1 is parallel to the coastline, and any one-way inlet for microplastics on the microplastic collection box 1 faces the sea or the coast. There are many installation methods for collecting plastic collection boxes, as shown in Figure 10 and Figure 11, for example: multiple microplastic collection boxes 1 are fixedly connected by anchor chains and arranged in a straight line or multiple microplastic collection boxes 1 The boxes are arranged staggeredly on the near-shore plane. According to the length of the coastline and the area of garbage collection, the number of microplastic collection boxes 1 can be appropriately selected. According to the reciprocating characteristics of seawater waves, as shown in Figure 1, when When the wave rushed from the right side to the left side, the movable valve plate 18 at the first microplastic one-way inlet port 3 opened towards the inside of the microplastic collection box 1, and the bulk garbage in the seawater was filtered by the microplastic filter screen 5, The microplastic particles in the seawater flow through the microplastic filter screen 5 and flow into the first cavity 7 of the microplastic collection box 1 from the first microplastic one-way inlet 3. Under the impact of the water flow, the seawater and the filter The net 6 contacts and passes through the filter screen 6 (the aperture of the filter screen 6 is less than or equal to the aperture of the maximum aperture filter screen membrane 12 on the frame 10), and enters into the second cavity 8 to the activity of the second microplastic one-way inlet port 4. The valve plate 18 exerts a thrust and closes the second microplastic one-way inlet 4. At this time, the seawater with microplastic particles in the microplastic collection box 1 is divided into two paths and flows out to the outside.

The cavity is divided into two cavities, and the action of collecting and separating the microplastic particles can be completed twice when the seawater reciprocates once, which improves the efficiency of microplastic collection. In addition, due to the existence of the filter screen 6, the first cavity 7 and the first cavity can be reduced. The filtration pressure of the filter membrane 12 in the microplastic separation device on the second cavity 8 improves the service life of the filter membrane 12 .

In addition, in order to prevent the microplastics in the frame unit 11 from overflowing, the two ends of the frame 10 are provided with a one-way closing mechanism, and the one-way closing mechanism includes a movable valve plate 16 arranged at the openings at both ends of the frame, and one end of the movable valve plate 16 is connected to the The frame 10 is flexibly connected, and the free end of the movable valve plate 16 on the frame 10 is provided with a stop plate 17 with an “L”-shaped cross section, and the stop plate 17 limits the movable valve plate 16 to the inside of the microplastic collection box 1 or the frame 10 That is to say, when the movable valve plate 16 is subjected to the impact force of seawater, the movable valve plate 16 can only rotate in one direction towards the inside of the frame 10. The advantage of this design is that the water in the microplastics collection box 1 can only It can flow into the frame 10 in one direction, effectively preventing the microplastics collected in the frame 10 from entering the microplastics collection box 1 along with the water flow, and improving the collection efficiency of the microplastics.
