Embodiment 1

[0027] Such as Figure 1 to Figure 3 As shown, the carbon dioxide generator includes:

[0028] The box body 1 is used to hold the electrolyte, the graphite electrode 2 and the cathode plate 3. The box body 1 in the present embodiment is an open container, and its upper port is sealed and connected to the partition 13 by the sealing ring 12, and the partition 13 seals the box. The inner cavity of the body 5 is divided into a lower cavity 56 and an upper cavity 55 isolated from each other; the vent 11 communicating with the inner cavity of the box body 1 is provided on the partition, and the positive electrode terminal 14 and the positive electrode terminal 14 respectively connected to the electrolytic circuit 4 The negative terminal 15 and the positive terminal 14 are electrically connected to the graphite electrode 2 , and the negative terminal 15 is electrically connected to the cathode plate 3 .

[0029] In this embodiment, the cross-section of the cathode plate 3 is “U” sh...

Embodiment 2 to 8

[0043] The structure of the carbon dioxide generator in Examples 2 to 4 is the same as that of Example 1, except that the composition of the electrolyte and the composition of the graphite electrodes are different. The details are shown in Table 1. The graphite in each embodiment in Table 1 is the balance, that is, the amount of graphite is 100% after being supplemented.

Abstract

The invention relates to a graphite electrode, a preparing method thereof and a carbon dioxide generator. The graphite electrode comprises the following components by weight, which are described in the specification, wherein an adhesive comprises at least one of phenolic resin, bisphenol-A epoxy resin and urea resin; a first additive is selected from at least one of polylactic acid, carbonic ester, monosaccharide, oligosaccharide and polymethyl acrylate; and a second additive is selected from at least one of carbon black, carbon nanotubes, silicon carbide, boron nitride, silicon oxide, aluminum oxide, zinc oxide, iron oxide, titanium dioxide, calcium carbonate, stearic acid, zinc stearate and calcium stearate. The content of carbon dioxide in gas obtained by electrolysis is higher than 10v%, and the gas output is stable. The carbon dioxide generator is particularly suitable for being used as a matched device in mosquito killing equipment and plant growth equipment, is convenient to change, is great in energy saving and consumption reducing effects and is friendly to the environment.

Description

technical field [0001] The invention relates to a graphite electrode, a preparation method thereof and a carbon dioxide generator. Background technique [0002] Graphite is used as an electrode for electrolysis to generate carbon dioxide. The content of carbon dioxide in the gas produced by electrolysis is between 1 and 2v%, and the concentration of carbon dioxide is very low. If used as an attractant for mosquitoes, the concentration of carbon dioxide produced by conventional graphite carbon dioxide generators cannot effectively attract mosquitoes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a graphite electrode which can greatly increase the concentration of carbon dioxide in the electrolysis gas under the same electrolysis conditions. [0004] Another technical problem to be solved by the present invention is to provide a preparation method of a graphite electrode that can greatly increase the concentrati...
