The embodiment of the invention provides a pollution treatment system based on a star-structure friction nano generator, which comprises: the system comprises a star-shaped engine 110, a contact separation type nano generator 120 arranged in each cavity of the star-shaped engine, a one-way gas circuit control module 130, a circuit management module 140 and an electrochemical degradation module 150; the star-shaped engine rotates along with the pushing of external mechanical energy to drive the piston of each chamber to move; the contact separation type nano generator generates electricity along with the movement of the piston; the unidirectional gas circuit control module is used for driving gas in an open environment to be introduced into the electrochemical degradation module by utilizing the movement of the piston so as to dissolve water-soluble pollutants in the gas into a degradation pool of the electrochemical degradation module; the circuit management module is used for managing the electric energy generated by the contact separation type nanometer generator and providing the electric energy for the electrochemical degradation module so as to degrade the water-soluble pollutants in the degradation pool.
Among the common gaseous pollutants, there is a class of polluting gases that are water soluble, such as sulfur oxides, nitrogen oxides, and the like. Compared with direct treatment, the pollutants are absorbed and enriched by the aqueous solution, and better degradation and treatment are facilitated.
Therefore, the embodiment of the invention utilizes the star-structure friction nano generator to introduce the gas in the open atmospheric environment into the aqueous solution by utilizing the control of the one-way gas path under the driving of the external mechanical energy (such as wind energy) so as to absorb the soluble pollutants in the aqueous solution. Meanwhile, along with driving, the friction nano generator generates electric energy based on the Maxwell displacement current principle, and pollutants in the water solution are degraded by combining an electrochemical system through circuit management and rectification. Based on the drive of natural energy such as wind, water flow and the like, the invention solves the problems of synchronous aqueous solution absorption and electrochemical degradation of soluble gas pollutants in open atmospheric environment by utilizing a friction nano generator with a star-shaped engine structure and one-way gas circuit control and matching with an electrochemical degradation system.
In one embodiment, the radial engine may be used in conjunction with a power drive, including but not limited to: wind power and water flow; when wind blows or water flow drives the power driving device, the star-shaped engine is driven to rotate. Of course, other mechanical energy may be used to drive the radial engine, for example, other new energy such as water flow may be used to drive the radial engine to rotate.
Further, the contact separation type nano-generator includes: the stacked friction nano-generator is formed by connecting more than one contact separation type nano-generator in series; the stacked friction nano-generator is connected end to end and is folded and placed in the cavity; when the piston in the chamber moves, the stacked friction nano-generator is in contact separation to generate a potential difference.
Specifically, in order to generate as much electric energy as possible with better utilization of space, 1 is a stacked triboelectric nanogenerator used in the present embodiment, which is composed of a contact separation type triboelectric nanogenerator of a plurality of cells. The base material polyester 1 was first cut into a plurality of circular shapes connected in series. On one hand, the substrate can provide support for other materials, and on the other hand, the bending can be guaranteed, so that the contact separation can be conveniently completed along with the movement of the piston to generate electric energy. Thereafter, 0.5mm thick foam 3 was attached to each round polyester unit as a buffer layer for the tribo nanogenerator. The electrode material was copper foil 4(30 μm), and the dielectric material was polytetrafluoroethylene film 5(80 μm). When the polytetrafluoroethylene 5 and the copper 4 are contacted with each other, the polytetrafluoroethylene 5 and the copper 4 are electrified in a friction mode, wherein the polytetrafluoroethylene 5 is negatively electrified, and the copper 4 is positively electrified. The generator units are connected in parallel. The above materials are used only in the present embodiment, and contact separation type friction nano-generator made of other materials can also be used in the present system.
Further, to that end, the circuit management module includes: and the rectification modules correspond to the chambers one by one and are used for converting electric energy generated by the contact separation type nano generator into direct current and connecting the direct current to the electrochemical degradation module.
Still further, the electrochemical degradation module comprises: the electrolytic cell is provided with a working electrode and a counter electrode in the electrolytic cell; when the circuit management module accesses direct current to the working electrode, including but not limited to a nickel electrode, and the counter electrode, including but not limited to a platinum electrode, the water soluble contaminants in the electrolytic cell degrade.

The main components of the current management module 12 are rectifier bridges, the number of which is the same as the number of chambers. After rectification, an electrocatalysis system is connected. In this embodiment, a mature electrocatalytic system is selected, in which the nickel foam electrode 13 serves as the working electrode and the platinum electrode 14 serves as the counter electrode. With the help of the wind cup 15, the wind energy can be converted into mechanical energy, and then the whole system is driven to work.
Please refer to the schematic plan view of the friction nano-generator and the one-way air path module of the radial engine structure. The piston motion can be completed by external mechanical force by using the core driving structure 6 of the radial engine. The figure shows an example of a friction nano-generator with a star-shaped engine structure consisting of five chambers 7. Along with external driving, the piston 8 can perform linear reciprocating motion, and further drives the friction nano generator 9 connected with the piston to continuously contact and separate to generate electric energy. In addition, due to the planar structure of the radial engine, a phase difference can be generated in the electric signals of the friction generator in the cavity. After rectification, different resistances are connected into an external circuit for testing, and the result shows that the average power of the combined action of the five chambers is larger than the sum of the independent actions of the five chambers within a certain external resistance range. In this embodiment, the external resistance ranges from 0 to 300 M.OMEGA..
In addition, on the basis of the above embodiment, in this embodiment, a rainwater collector may be further disposed in the degradation tank, and is used for collecting rainwater into the degradation tank, so as to realize the enrichment of water-soluble pollutants.

And (3) introducing the nitrogen oxide into the box, and reducing the concentration of the nitrogen oxide in the box to 0 after 180min under the condition that the initial concentration is 1 mg/L. Therefore, the system can effectively absorb soluble pollutants in the gas.
