[0022] Figure 1 The present invention is a schematic structural diagram of a circulating power generation system using clean energy according to an embodiment of the present invention. DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1As shown, a cyclic power generation system 100 using clean energy, the power generation system 100 includes a power generation device 110, a processing device 120 and a biogas tank 130. The power generation device 110 includes a thermal power unit 111, and the thermal power unit 111 is connected to the processing device 120, and is used to supply power to the processing device 120. The biogas tank 130 is connected to the processing device 120, and is used to receive the residual material generated after the processing of the processing device 120 is completed to generate biogas. The biogas tank 130 is also connected to the thermal power unit 111, and is used to provide the biogas to the thermal power unit 111 for combustion and power generation.

[0025] Specifically, Figure 1 As shown, the thermal power generation unit 111 supplies power to the processing device 120, and the processing device 120 can work after receiving the power and produce residual material after the work processing is completed. The residual material is transported to the biogas tank to produce biogas and biogas liquid. The biogas liquid can be used as agricultural waste to help agricultural products grow, and the excess biogas liquid can also be used to produce fertilizers. The biogas is transported to the thermal power generation unit 111 for combustion, thereby driving the thermal power generation unit 111 to generate electricity.

[0026] Furthermore, the processing equipment 120 also produces biomass solid fuel after the processing is completed, and the biomass solid fuel is used to be transported to the thermal power unit 111 for combustion and power generation. Specifically, after the processing equipment 120 is completed, in addition to the residual material, it will also produce biomass solid fuel. The biomass solid fuel produced by the processing equipment 120 is directly transported to the thermal power unit 111 for combustion and power generation. It is not difficult to understand that the thermal power unit can generate electricity by burning biogas or by burning biomass solid fuel. The thermal power unit generates electricity to drive the processing equipment to work, and the processing equipment produces residual material and biomass solid fuel after the processing is completed. The biomass solid fuel is directly transported to the thermal power unit for power generation. The residual material is first transported to the biogas tank to produce biogas, and the biogas is transported to the thermal power unit for power generation. In this way, a recyclable power generation system using clean energy as fuel can be formed. After the clean energy is burned, it supplies power to the processing equipment, avoiding the waste of biomass resources, without burning fossil energy, and without relying on external energy. Biogas and biomass solid fuel are both types of clean energy.

[0027] For example, Figure 1As shown, the processing equipment 120 includes industrial processing equipment 121 and agricultural processing equipment 122, and the industrial processing equipment 121 and agricultural processing equipment 122 are electrically connected to the thermal power unit 111 respectively. The industrial processing equipment 121 produces industrial residues that can be fermented to produce biogas after the industrial processing is completed, and the industrial residues are transported to the biogas tank 130. The agricultural processing equipment 122 produces agricultural residues after the agricultural processing is completed, and the agricultural residues include a first sub-agricultural residue that can be fermented to produce biogas and a second sub-agricultural residue that can be processed into solid fuel. Among them, the first sub-agricultural residue is transported to the biogas tank 130. The second sub-agricultural residue is processed by the industrial processing equipment 121 to become biomass solid fuel and transported to the thermal power unit 111.

[0028] Specifically, Figure 1 As shown, the industrial processing equipment 121 is powered by the thermal power unit 111, and the industrial processing equipment 121 can be industrial equipment for processing agricultural products and animal husbandry-related products. For example, the industrial processing equipment 121 can process meat and eggs from animal husbandry into cooked food, process agricultural products as animal husbandry feed, process agricultural solid waste such as straw and rice straw as biomass fuel, process duck down and goose down as textiles, process biogas slurry to produce fertilizer, etc. The industrial processing equipment is powered by the thermal power unit to provide electrical energy, and the industrial waste such as wastewater and waste generated by it is used in a biogas digester to generate biogas.

[0029] Furthermore, the processing equipment 120 further includes a livestock processing equipment 123, which is electrically connected to the thermal power generation unit 111. After the livestock processing is completed, the livestock processing equipment 123 produces livestock waste that can be fermented to produce biogas, and the livestock waste is transported to the biogas tank 130.

[0030] If agriculture and animal husbandry require special environments such as temperature and humidity, this can be achieved by supplying electricity and steam to the agricultural processing equipment 122 and the animal husbandry processing equipment 123 through the thermal power unit 111. The agricultural processing equipment 122 will produce a first sub-agricultural residue and a second sub-agricultural residue after the agricultural processing is completed. The first sub-agricultural residue can be fermented to produce biogas, which is transported to the biogas pool. The second sub-agricultural residue can be processed by the industrial processing equipment 121 to become biomass solid fuel and directly transported to the thermal power unit 111. After the animal husbandry processing is completed, the animal husbandry processing equipment 123 can produce animal husbandry waste that can be fermented to produce biogas, such as feces, and transport it to the biogas pool.

[0031] The circulating power generation system using clean energy in the embodiments of the present disclosure can complete the production of the entire system without burning fossil energy. No external energy supply is required, and the system's circular production can be achieved by utilizing the waste generated in the system. Industrial waste, agricultural waste, and livestock manure are fully utilized to maximize resource utilization, reduce resource waste, and effectively reduce production costs. In addition, the system can be used to convert cheap agricultural products, poultry, livestock, etc. into more expensive cooked food, etc., thereby improving economic benefits. Solid waste such as agricultural straw can be processed into biomass fuel to maximize resource utilization.

[0032] For example, Figure 1 As shown, the power generation equipment 110 also includes a wind power generation device 112 and a solar power generation device 113. The wind power generation device 112 and the solar power generation device 113 are respectively connected to the processing equipment 120 for supplying power to the processing equipment 120. Through the wind power generation device 112 and the solar power generation device 113, when energy is insufficient, wind energy and light energy can be added to supplement energy.

[0033] For example, Figure 1 As shown, the power generation device 110 is also connected to the power grid, and is used to supply excess power to the power grid after supplying power to the processing device 120. Specifically, the power generation device 110 supplies power to the processing device 120 first, and if there is excess power after supplying power to the processing device 120, it can continue to supply power to the power grid, so that the excess power can be connected to the grid.

[0034] For example, Figure 1 As shown, the thermal power unit 111 includes a combustion boiler (not shown in the figure), a steam turbine (not shown in the figure), a generator (not shown in the figure) and a transformer (not shown in the figure). The combustion boiler is used to receive the biogas and the biomass solid fuel, and the combustion boiler is sequentially connected to the steam turbine, the generator and the transformer, and the transformer is electrically connected to the processing equipment 120 to supply power to the processing equipment 120.

[0035] Furthermore, the power generation system 100 further includes a heat supply pipe (not shown in the figure). One end of the heat supply pipe is connected to the combustion boiler, and the other end of the heat supply pipe is connected to the processing equipment 120 to supply heat to the processing equipment 120 .

[0036] Specifically, Figure 1As shown, the thermal power unit 111 includes a combustion boiler, a steam turbine, a generator, a transformer and a heating pipeline, which together constitute the power supply and heating part of the thermal power unit 111. The industrial processing equipment 121, the agricultural processing equipment 122 and the animal husbandry processing equipment 123 together constitute the user part, that is, the processing equipment 120. And the waste (residue) generated by industry, agriculture and animal husbandry constitutes the fuel part of the thermal power unit 111. The combustion boiler is a boiler that can burn two media, which can burn biogas produced by fermentation of wastewater, feces, etc. produced by industry, agriculture and animal husbandry, and can also burn biomass solid fuels made of agricultural straw, etc. The boiler burns fuel to generate high-temperature and high-pressure water vapor. On the one hand, it generates electricity by driving the steam turbine and the generator, and then converts the voltage through the transformer to supply it to the industrial processing equipment 121, the agricultural processing equipment 122 and the animal husbandry processing equipment 123 for residents to use. On the other hand, the high-temperature and high-pressure water vapor can be supplied to the processing equipment 120 such as the industrial processing equipment through the heating pipeline for production, and can also provide winter heating to residential users.

[0037] The embodiment of the present disclosure uses a cyclic power generation system that uses clean energy to supply power and steam to the processing equipment through a thermal power unit, thereby providing electrical energy and kinetic energy to the processing equipment. This system realizes a complete clean energy cycle, using waste generated by industry, agriculture and animal husbandry as fuel, and after combustion, using a thermal power unit to supply power and heat to the processing equipment, thereby avoiding the waste of biomass resources, eliminating the need to burn fossil energy, and eliminating the need to rely on external energy.

For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and substance of the present disclosure, and these modifications and improvements are also considered to be within the scope of protection of the present disclosure.
