Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of environmental protection, and particularly relates to an electrocatalytic water treatment technology, and more particularly to a combined module of a three-dimensional electrode electrolytic cell filled with circular tube type catalytic materials. Background Art
[0002] At present, in the field of water treatment technology, there are technical defects in two aspects. First, for the disinfection and sterilization technology of drinking water, it has evolved from the previous method of adding bleaching powder for oxidation and sterilization to the method of chlorine dioxide disinfection and then to the currently commonly used ozone plus ultraviolet light sterilization technology. They all have their fatal flaws: bleaching powder disinfection introduces a large amount of calcium ions and chloride ions and cannot be used as direct drinking water; in the chlorine dioxide disinfection method, not only does chlorine gas have an unpleasant smell, but the hypochlorous acid dissolved in water is extremely harmful to the human body and is also carcinogenic; for ozone sterilization, even if the ozone dissolved in the water is slightly exceeded, once it enters the human body, there is a great carcinogenic risk. In fact, this is also one of the reasons for the frequent occurrence of cancers in China in recent years.
[0003] Secondly, for the treatment of heavy metal ions in water, in addition to chemical or ordinary electrochemical oxidation-reduction and coagulation precipitation degradation, the remaining deep treatment methods for trace ions usually include: adsorbent adsorption method, ion exchange resin adsorption and regeneration method, as well as reverse osmosis technology and electrodialysis technology. Currently, in the environmental protection market, the better technologies that can more thoroughly degrade toxic and harmful ions in water and at the same time enable the equipment to be used for a long time are nothing more than the use of reverse osmosis technology or electrodialysis technology. However, they all have their different drawbacks: the adsorption method will bring trouble in subsequent solid waste or regeneration processes; both reverse osmosis technology and electrodialysis technology will have concentrated water that needs to be treated again, and at the same time, the membrane replacement cost is high.
[0004] In order to overcome the above drawbacks, it is very necessary to develop a new technology with strong disinfection and sterilization ability without leaving a large amount of oxidants and at the same time having the function of removing heavy metal ions. For this reason, the utility model designs a combined module of a three-dimensional electrode electrolytic cell filled with circular tube type catalytic materials for the disinfection and deep treatment of toxic and harmful viruses, bacteria and trace toxic and harmful ions in polluted water to solve the above problems. Content of the Utility Model
[0005] In view of the defects of the existing technology for water pollution treatment, especially for the disinfection and deep treatment technology of toxic and harmful viruses, bacteria and trace toxic and harmful ions, the utility model designs a combined module of a three-dimensional electrode electrolytic cell filled with circular tube type catalytic materials. This module can completely disinfect bacteria and viruses in water, and at the same time deeply degrade toxic and harmful ions in polluted water, with high production efficiency and in line with the new trend of environmental protection development. The utility model is realized by adopting the following technical solutions:
[0006] A combined module of a three-dimensional electrode electrolytic cell filled with a tubular catalytic material, including a single electrolytic cell and a combined module of multiple electrolytic cells; the single electrolytic cell (as Figure 2 shown) consists of two "three-dimensional electrodes filled with tubular catalytic materials", a positive one and a negative one (as Figure 1 shown); the combined electrolytic cell module (as Figure 3 shown) is a combined electrolytic cell device composed of at least two pairs or more of single electrolytic cells connected in series. Each "three-dimensional electrode filled with tubular catalytic material" of this device includes: a graphite conductive column, a catalytic material filling bin, a porous mesh plate, a slag discharge port, a tubular electrolytic cell housing, etc.
[0007] Furthermore, the "graphite conductive column" of the "three-dimensional electrode filled with tubular catalytic material" as described above is arranged on the "tubular electrolytic cell housing". One end of the graphite conductive column protrudes outside the housing and is connected to the power supply through a wire or a connector, and the other end extends into the "catalytic material filling bin".
[0008] Furthermore, the "catalytic material filling bin" of the "three-dimensional electrode filled with tubular catalytic material" as described above is arranged inside the "tubular electrolytic cell housing". A "porous mesh plate" is respectively arranged on both the left and right sides. The space between the housing and the porous mesh plate is the "catalytic material filling bin", and its space size can be flexibly designed according to the water treatment volume.
[0009] Furthermore, there are two "porous mesh plates" in the "three-dimensional electrode filled with tubular catalytic material" as described above. One of them can be fixed with screws, and the other is a movable plate for facilitating the loading and unloading of the catalytic material (as Figure 5 shown). The aperture of this "porous mesh plate" is designed to be 1 - 5 mm according to the water flow velocity and the particle size of the catalytic material. The requirement is that it is smaller than the particle size of the catalytic material, and only water and tiny particles detached from the catalytic material can pass through, but the catalytic material cannot flow out.
[0010] Furthermore, the "tubular electrolytic cell housing" of the "three-dimensional electrode filled with tubular catalytic material" as described above is designed as a tubular (or cylindrical) housing with a connecting frame (as Figure 4 , 5 , 6 shown), which is connected by screw connectors or other connectors. The housing is provided with an installation interface for the "graphite conductive column", a "slag discharge port" for connecting the slag discharge pipe, and a fixing place for fixing the "porous mesh plate".
[0011] Furthermore, the "slag discharge port" of the "three-dimensional electrode filled with tubular catalytic material" as described above is designed at the lower part of the "tubular electrolytic cell housing" of this three-dimensional electrode, and at the same time is outside the lower part of a "porous mesh plate" (as Figure 5As shown in the figure, in order to standardize the shape of each electrolytic cell, a "porous screen plate" adjacent to the "slag discharge port" can be inclined. The slag discharge port is exactly at the lower part of the shell of the inclined area, so as to ensure that the overall three-dimensional electrolytic cell has a regular circular tube shape or cylindrical shape (as Figure 5 shown).
[0012] Furthermore, the "electrolytic cell combination module" described above is composed of a combined electrolytic cell device in which at least two pairs or more of single electrolytic cells are connected in series (as Figure 3 shown); a combined electrolytic cell device composed of 2 to 15 pairs of single electrolytic cells connected in series can be designed as a water treatment module, and each unit module is fixed to treat a certain amount of water (such as 1 ton of water per hour). If more water needs to be treated, multiple modules are connected in parallel; each unit module is required to be in a flat mode, with a slag discharge port and a slag discharge pipeline at the bottom.
[0013] Furthermore, both sides of the "combination module of a three-dimensional electrode electrolytic cell filled with a circular tube type catalytic material" described above can be connected to the water circuit with a pot lid type sealed shell.
[0014] Advantages of the present utility model
[0015] 1. The present utility model overcomes many disadvantages in the conventional methods for treating toxic and harmful ions in polluted water. For example, the adsorption method will bring troubles in subsequent solid waste or regeneration processes, and both the reverse osmosis technology and the electrodialysis technology have high membrane replacement costs and the problem that the concentrated water needs to be treated again. In view of the defects of the existing water pollution treatment technology, especially for the disinfection and deep treatment technology of toxic viruses, bacteria and trace toxic and harmful ions, a combination module of a three-dimensional electrode electrolytic cell filled with a circular tube type catalytic material is designed. This module can completely disinfect bacteria and viruses in water, and at the same time deeply degrade toxic and harmful ions in polluted water, with high production efficiency, meeting the new trend of environmental protection development.
[0016] 2. The present utility model electrolyzes under a low current density state through the action of a catalyst. This method can generate sufficient active hydrogen peroxide radicals and other active oxygen molecules for sterilization and disinfection to quickly kill bacteria and viruses. At the same time, through the adsorption of its high specific surface area catalytic material, heavy metal ions in water are concentrated, and their oxidation-reduction overpotential is greatly reduced. Finally, harmful ions such as heavy metal ions are reduced or oxidized into solid precipitates or ions that are easy to handle, so as to achieve the purpose of purifying water.
[0017] 3. The utility model can also separate water molecules with a cluster macromolecular structure into small molecule water, and at the same time, according to user needs, by changing the catalyst, finally obtain small molecule hydrogen-rich water or oxygen-rich water beneficial to the human body.

[0025] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings.
[0026] As shown in Figure 1 、 2 、3, 4, 5, 6, the "combination device of a three-dimensional electrode electrolytic cell filled with tubular catalytic material" of the present utility model includes a single electrolytic cell and a combined module of multiple electrolytic cells; the single electrolytic cell (as shown in Figure 2 ) is composed of two "three-dimensional electrodes filled with tubular catalytic material" (as shown in Figure 1 ), one positive and one negative; the combined module of electrolytic cells (as shown in Figure 3 ) is a combined electrolytic cell device composed of at least two pairs or more of single electrolytic cells connected in series. Each "three-dimensional electrode filled with tubular catalytic material" of this device includes: graphite conductive column 1, catalytic material filling bin 2, porous screen plate 3, slag discharge port 4, tubular electrolytic cell housing 5, etc.
[0027] As a further solution of the present utility model,
[0028] The "graphite conductive column 1" of the "three-dimensional electrode filled with tubular catalytic material" as described above is arranged on the "tubular electrolytic cell housing 5". One end of the graphite conductive column protrudes outside the housing and is connected to a power source through a wire or a connector, and the other end extends into the "catalytic material filling bin 2" to conduct electricity for the catalytic material inside the three-dimensional electrode, so that each catalytic material is charged and becomes a cathode or an anode.
[0029] The "catalytic material filling bin" of the "three-dimensional electrode filled with tubular catalytic material" as described above is arranged inside the "tubular electrolytic cell housing". A "porous screen plate" is respectively arranged on the left and right sides. The space between the housing and the porous screen plate is the "catalytic material filling bin", and its space size can be flexibly designed according to the water treatment volume; the "catalytic material filling bin 2" is filled with granular or porous foam-like catalytic materials with a high specific surface area (such as granular activated carbon, carbon felt, alloy particles, granular activated carbon loaded or sintered with a catalyst, carbon felt, and other granular catalytic materials).
[0030] One of the two "porous screen plates 3" inside the "three-dimensional electrode filled with tubular catalytic material" as described above can be fixed with screws, and the other is a movable plate for facilitating the loading and unloading of catalytic materials (as Figure 5 shown). The space between the two "porous screen plates 3" is the "catalytic material filling bin 2", and its space size can be flexibly designed according to the water treatment volume; the aperture of the "porous screen plate 3" is designed to be 1 - 5 mm according to the water flow velocity and the particle size of the catalytic material. The requirement is that it is smaller than the particle size of the catalytic material, and only water and tiny particles detached from the catalytic material can pass through, but the catalytic material cannot flow out.
[0031] The "tubular electrolytic cell housing 5" of the "three-dimensional electrode filled with tubular catalytic material" as described above is designed as a circular tube (or cylinder) - shaped housing with a connecting frame (as Figure 4 , 5 , 6 shown), and is connected with screws or other connectors. The housing is provided with an installation interface for the "graphite conductive column 1", a "slag discharge port 4" for connecting a slag discharge pipe, and a fixing place for fixing the "porous screen plate 3".
[0032] The "slag discharge port 4" of the "three-dimensional electrode filled with tubular catalytic material" as described above is designed at the lower part of the "tubular electrolytic cell housing 5" of this three-dimensional electrode, and is simultaneously located at the lower outer side of a "porous screen plate 3" (as Figure 5 shown) for cleaning the tiny particles of the catalytic material that have fallen off and are carried out of the "catalytic material filling bin 2" by the water flow; in order to standardize the shape of each electrolytic cell, a "porous screen plate 3" adjacent to the "slag discharge port 4" can be inclined, and the slag discharge port 4 is exactly at the lower part of the housing in the inclined area, so as to ensure that the overall shape of the three-dimensional electrolytic cell is a regular circular tube (cylinder) shape (asFigure 5 as shown
[0033] The "electrolytic cell combination module" as described above is composed of a combined electrolytic cell device in which at least two pairs or more of single electrolytic cells are connected in series; a combined electrolytic cell device composed of 2 to 15 pairs of single electrolytic cells connected in series can be designed as a water treatment module, and each unit module is fixed to treat a certain amount of water (such as 1 ton of water per hour). If more water needs to be treated, multiple modules are connected in parallel; each unit module is required to be in a flat mode, with a slag discharge port and a slag discharge pipeline at the bottom.
[0034] The two sides of the "combination module of a three-dimensional electrode electrolytic cell filled with a tubular catalytic material" as described above can be connected to the water circuit with a pot cover-shaped sealed housing. When purifying water, the polluted water enters from one side, the purified water comes out from the other side, and the residue is discharged from the slag discharge port.
[0035] The working process of the "combination module of a three-dimensional electrode electrolytic cell filled with a tubular catalytic material" of the present utility model includes: the polluted water flows in from one side of the module of the present utility model, and at the same time, electricity is applied. The catalytic material particles (or porous foam) inside the three-dimensional electrode are simultaneously charged positively or negatively according to the cathode and anode, becoming countless cathodes and anodes. When the water flows through the module, under the action of the catalyst, the dissolved oxygen in the water is oxidized and reduced to hydroxyl radicals or hydrogen peroxide, and at the same time, a strong killing effect on bacteria and viruses is produced; in addition, the high voltage will also break through the cell walls of viruses or bacteria, killing viruses and bacteria. Secondly, the catalytic material can adsorb and concentrate heavy metal ions, greatly reducing their reduction overpotential, and finally the heavy metal ions are reduced and deposited on the cathode. Finally, the purified water comes out from the other end of the module of the present utility model.
