Embodiment 1

[0062] Example 1 Effect of ion concentration gradient difference on nanofluid power generation

[0063] 1) Preparation of PAAM

[0064] First anodize the polished aluminum sheet with a purity of 99.99% for 6 hours, then soak it in chromic acid for 12 hours to remove the primary oxide layer, then perform secondary anodic oxidation for 1 hour, and then use saturated copper chloride solution to remove the aluminum oxide film Clean the unreacted aluminum on the back, and use phosphoric acid to pass through holes for about 100 minutes to prepare a circular PAAM with a diameter of 1 cm and a thickness of 4.4 μm;

[0065] Wherein, the anodic oxidation uses a 0.4 mol / L oxalic acid solution, a constant voltage of 30V, and a constant temperature of 10°C.

[0066] 2) Assembly of the electrolytic cell

[0067] The PAAM prepared in 1) was fixed at the openings (completely covered) of the pool shells with two side openings in the middle, and an equal amount of KCl solution and pure water ...

Embodiment 2

[0076] Example 2 Effect of Red Ink Modified PAAM on Nanofluid Power Generation

[0077] 1) Preparation of red ink modified PAAM

[0078] After preparing PAAM using the same method as in Example 1, use 3.05×10 -5 g / mL red ink solution for about 1 month.

[0079] 2) Assembly of the electrolytic cell

[0080] Same as Example 1, wherein the concentration of KCl solution is 1mol / L.

[0081] 3) Measurement of volt-ampere characteristic curve

[0082] Same as Example 1.

[0083] 4) Analysis of results

[0084] The SEM image of the PAAM surface after the red ink modification prepared by the present embodiment is as follows Figure 9 shown. Visible, with figure 2 In contrast, PAAM soaked in red ink for a long time formed a new nanoporous membrane structure.

[0085] The volt-ampere characteristic curve measured in this embodiment is as follows Figure 10 shown. It can be seen from the figure that when the applied voltage is zero, the current value is 511.55nA greater than z...

Embodiment 3

[0086] The influence of the amount of embodiment 3 colloidal particles on nanofluid power generation

[0087] 1) Preparation of PAAM

[0088] Same as Example 1.

[0089] 2) Assembly of the electrolytic cell

[0090] The electrolytic cell was assembled using the same method as in Example 1, wherein the concentration of the KCl solution was 1mol / L, the difference being that, on the KCl solution side, red ink solutions of different concentrations were also added.

[0091] 3) Measurement of volt-ampere characteristic curve

[0092] Same as Example 1.

[0093] 4) Analysis of results

[0094] This embodiment studies the short-circuit current, open-circuit voltage and maximum output power under different red ink solution concentrations, such as Figure 11-13 shown (where Figure 13 The dotted line in represents the power generation without colloidal particles). When the red ink solution concentration is 2.6×10 -5 ~4.2×10 -5 In the g / mL range, good results can be obtained; when...

Abstract

The invention provides a nano fluid power generation method, an electrolytic tank device and a nano porous membrane; the method comprises the following steps: 1, the nano porous membrane is prepared;2, the nano porous membrane prepared in the step 1 is fixed at the openings of two tank shells, wherein the tank shells have openings in the middle positions of the side surfaces, the two tank shellsare connected, an electrolyte solution and a colloidal solution are added into the tank shell on one side, and equal amount of pure water is added into the tank shell on the other side; and 3, same kinds of Ag / AgCl electrodes are placed on the left and right sides of the tank shells, a voltage source and an ampere meter are connected, and an external voltage is applied to form the electrolytic tank device for reverse electrodialysis. The nano fluid power generation efficiency is regulated and controlled based on the ion selective transmission mechanism of the colloidal particles and the nano porous membrane; and the advantages of being low in environmental pollution, low in production cost, high in application value, high in practicability and wide in application range can be achieved.

Description

technical field [0001] The invention relates to a method for generating electricity by nanofluid, an electrolytic cell device thereof, and a nanoporous membrane, and in particular to a method for regulating and controlling nanofluid power generation through colloids, an electrolytic cell device, and a nanoporous anodic aluminum oxide membrane. It belongs to the technical field of concentration gradient difference power generation. Background technique [0002] At any solid-liquid interface, surface ionization, ion adsorption, and ion dissolution can charge the surface of a solid. Due to the electrostatic interaction, the surface charge will attract opposite ions in the solution, thereby forming an electric double layer (EDL) at the solid-liquid interface, which in turn affects the flow behavior of the fluid. For both macroscopic and microscopic fluids, it is difficult to observe the influence of the surface charge of objects because the bulk effect tends to dominate. Howev...
