Background technique

Water purification refers to the process of removing pollutants from raw water. Its purpose is to achieve the effect of purifying water by a specific procedure. In the prior art, the water is purified by filtration or disinfection or a combination of the two.

The contact area is limited by the shape and size of the container and the equipment, the purification efficiency is relatively low, and the purification is not thorough enough.

The photocatalytic reaction is a kind of catalytic reaction that can effectively decompose, purify and disinfect. However, because the photocatalytic reaction requires liquid, solid catalysts and light to be processed, the solid, liquid and light are more fully integrated into one. Increasing the combined area of the three of them is a difficult problem for photocatalytic reactions.

Summary of the invention

In view of the above problems, the present invention discloses a heterogeneous catalytic reactor. By forming a closed gas chamber, the liquid flows in the form of a liquid film. Under the action of the catalytic reaction device, the contact area of the liquid catalytic reaction is increased, and the liquid Processing efficiency.

The present invention is achieved through the following measures:

The upper part of the purification reaction chamber is provided with at least one water inlet channel capable of forming a water film. The water inlet channel is connected to the raw water chamber. The treatment liquid of the raw water chamber can form a water film through the water inlet channel and enter the purification reaction. Indoor; the bottom or lower part of the purification reaction chamber has at least one water outlet that can form a water film, a water outlet channel with a switch, or a water outlet channel with a reverse bend that can form a water seal, that is, the bottom of the purification reaction chamber Or the lower part has at least one of a water outlet and a water outlet; a catalytic reaction device capable of processing the treatment liquid is arranged inside or outside the purification reaction chamber. The bottom or lower part of the purification reaction chamber may be sealed by a water body or a valve, so that an air chamber can be formed in the purification reaction chamber.

In some embodiments, a heterogeneous catalytic reactor provided by the present invention includes a raw water chamber for containing treatment liquid, and at least one purification reaction chamber is provided below or inside the raw water chamber; A sealed hollow container, the purification reaction chamber is provided with at least one water inlet channel capable of forming a water film, the water inlet channel is connected to the raw water chamber, and the treatment liquid in the raw water chamber can be formed after passing through the water inlet channel A water film enters the purification reaction chamber; the bottom or lower part of the purification reaction chamber has at least one water outlet channel capable of forming a water film, a water outlet with a switch, or a water outlet with a reverse bend that can form a water seal; A catalytic reaction device capable of processing the treatment liquid is arranged inside or outside the purification reaction chamber.

In the above-mentioned heterogeneous catalytic reactor of the present invention, one of the preferred solutions is that the total flow rate of the water outlet is less than or equal to the total flow rate of the water inlet channel; the diameter or the water flow width of the water inlet channel is 2*10 ^-5 -8mm, and the diameter or water width of the water outlet is 0.1-8mm. In another preferred embodiment, the diameter or width of the water inlet channel is 2*10 ^-7 -8mm (for example, 2*10 ^-7 mm, 5*10 ^-7 mm, 8*10 ^-7 mm, 1* 10 ^-6 mm, 2*10 ^-6 mm, 5*10 ^-6 mm, 8*10 ^-6 mm, 1*10 ^-5 mm, 2*10 ^-5 mm, 5*10 ^-5 mm, 1*10 ^-4 mm, 2*10 ^-4 mm, 5*10 ^-4 mm, 1*10 ^-3 mm, 0.01mm, 0.02mm, 0.2mm, 0.1mm, 1mm, 5mm, 8mm, etc.), the water outlet The diameter or the width of the water passage is 0.01-8mm (for example, 0.01mm, 0.05mm, 0.1mm, 0.5mm, 1mm, 5mm, 8mm, etc.). When the diameter or the width of the water inlet channel is less than 1*10 ^-5 mm, the diameter or the width of the water inlet channel is at the nanometer level, which will help to achieve further screening of the substances in the liquid, so as to achieve Better filtering and sieving effect. Further, when the diameter or the width of the water inlet channel is 2*10 ^-7 mm to 2*10 ^-6 mm, the separation of the gas can be achieved.

The working principle of the structure of the present invention is that since the upper part of the purification reaction chamber communicating with the raw water chamber has a water inlet channel, the lower part of the purification reaction chamber has a water outlet. When the diameter of the water inlet channel is less than a certain value, the surface tension of the liquid will form a water seal at the water inlet channel. A liquid film is formed due to the surface tension of the liquid. This liquid film separates the liquid and gas on both sides of it. At this time, as long as one side of the space on both sides of the separation is closed, water will not flow through the liquid film. At this time, both sides of the liquid film are equal pressure. When the pressure on both sides of the liquid film is not equal, the liquid will flow from the high pressure side to the low pressure side. When the raw water chamber side of the equipment is high pressure, the liquid in the raw water chamber will enter the purification reaction chamber through the water inlet channel. Since the total diameter of the water outlet is smaller than the total diameter of the water inlet channel, and each single hole is smaller than a certain value, a water film can be formed in the hole, or because there is a water seal formed by a backwater bend outside the water outlet, Make the purification reaction chamber form a sealed gas chamber. The pressure of the purification reaction chamber will become larger and larger as the treatment liquid continues to flow in through the water inlet channel. When the pressure is equal to the liquid pressure difference and the atmospheric pressure, a dynamic balance is formed. And because the single hole diameter of the water inlet channel and the water outlet is less than a certain value, the liquid in the raw water chamber flows through the water inlet channel and is affected by the gas pressure in the purification reaction chamber, the adsorption force of the liquid and the purification reaction chamber wall, its own gravity and the flow rate. The joint action takes the form of a water film and enters the purification reaction chamber along the wall of the purification reaction chamber. The liquid in the purification reaction chamber is discharged through the water outlet that can also form a water film. The water outlet speed is controlled by the flow rate of the water outlet. When the structure is equipped with a water outlet outside the water outlet, the water seal formed by the water outlet and the water film at the upper water inlet channel complete the air chamber closure. This structure does not make special requirements for the size of the water outlet channel. . Since the purification reaction chamber is provided with a catalytic device capable of catalytically treating the liquid inside or outside, the water flowing in the form of a water film can be fully catalytically treated.

The above structure can also be controlled by a water outlet with a switch. When the liquid in the raw water chamber begins to enter the purification reaction chamber, close the switch and the purification reaction chamber forms a sealed container. After the liquid enters the purification reaction chamber, the pressure of the purification reaction chamber When the pressure is equal to the liquid pressure difference and atmospheric pressure, the liquid stops entering the purification reaction chamber. When the switch is turned on and the flow rate of the water outlet is controlled, a dynamic balance will be formed. The liquid in the raw water chamber enters the purification reaction chamber as a water film, and the liquid in the purification reaction chamber is discharged through the switch. The water outlet speed is controlled by the water outlet switch. As long as there is a water seal on the inner side of the switch, the purification reaction chamber is airtight, forming a sealed air chamber. Since the purification reaction chamber is provided with a catalytic device capable of catalytically treating the liquid inside or outside, the water in the form of a water film can be fully catalytically treated.

In the above-mentioned heterogeneous catalytic reactor of the present invention, another preferred solution is that a water purification chamber is provided at the lower part of the purification reaction chamber, and at least one water film can be formed between the purification reaction chamber and the water purification chamber. The water outlet, the flow rate of the water outlet is equal to the flow rate of the water inlet channel; the water purification chamber is a sealed container with at least one through hole on the top or side wall; the raw water chamber is The sealed container is provided with at least one through hole on its bottom or side wall.

In the reactor with the above structure, a raw water chamber and a purification chamber are respectively provided at the upper and lower ends of the purification reaction chamber. When the raw water chamber is located above, the liquid in the raw water chamber enters the purification reaction chamber through the water inlet channel in the form of a water film and enters the purification reaction. The liquid in the room enters the purification room through the water outlet. When the diameter of the water inlet channel and the water outlet is less than a certain value, the surface tension of the liquid will form a water seal at the water inlet channel and the water outlet. Due to the surface tension of the liquid, a liquid film will be formed, and this liquid film will separate Open the liquid and gas on both sides. Since the raw water chamber is connected to the clean water chamber, the pressures of both sides are kept in balance. The liquid in the raw water chamber can flow downward due to gravity. The liquid in the raw water chamber passes through the inlet channel in the form of a water film, and flows in the form of a water film in the purification reaction chamber. Since the catalytic reaction device is arranged inside or outside the purification reaction chamber, the liquid can be processed more fully.

Since both the raw water chamber and the water purification chamber are provided with through holes, the through holes are used for exhausting air during the downward flow of the liquid to balance the pressure. It is also possible to connect the raw water chamber and the clean water chamber to maintain a balance up and down so that the liquid flows downward by gravity.

After all the liquid in the raw water chamber flows through the purification chamber and enters the water purification chamber, the equipment can also be turned over. The same principle, the liquid enters the raw water chamber from the purification reaction chamber and is processed again. It can be flipped repeatedly to carry out the catalytic reaction many times.

When there is a switch on the through hole of the raw water chamber and the water purification chamber, the pressure of the two can be adjusted by the switch, and the flow and flow rate can be adjusted.

Further, when the diameter or the width of the water inlet channel is 2*10 ^-7 mm to 2*10 ^-6 mm, the separation of the gas can be achieved.

The working principle of the structure of the present invention is that the purification reaction chamber is located inside the raw water chamber, and the liquid in the raw water chamber enters the purification reaction chamber through the water inlet channel of the purification reaction chamber. Since the total diameter of the water outlet is smaller than the total diameter of the water inlet channel, the purification reaction chamber forms a sealed air chamber. The pressure in the purification reaction chamber is getting higher and higher. When the pressure is equal to the liquid pressure difference and the atmospheric pressure, a dynamic balance is formed. And since the diameter of the water inlet channel and the water outlet is less than a certain value, the liquid in the raw water chamber enters the purification reaction chamber in the form of a water film, and the liquid in the purification reaction chamber is also discharged from the water outlet through the water film. Flow control of the nozzle. Since the purification reaction chamber is provided with a catalytic device capable of catalytically treating the liquid inside or outside, the water in the form of a water film can be fully catalytically treated.

The above structure can also be controlled by a water outlet with a switch. When the liquid in the raw water chamber begins to enter the purification reaction chamber, close the switch and the purification reaction chamber forms a sealed container. After the liquid enters the purification reaction chamber, the pressure of the purification reaction chamber When the pressure is equal to the liquid pressure difference and atmospheric pressure, the liquid stops purifying the reaction chamber. When the switch is turned on and the flow rate of the water outlet is controlled, a dynamic balance will be formed. The liquid in the raw water chamber enters the purification reaction chamber as a water film, and the liquid in the purification reaction chamber is discharged from the water outlet, and the water outlet speed is controlled by the water outlet. Since the purification reaction chamber is provided with a catalytic device capable of catalytically treating the liquid inside or outside, the water in the form of a water film can be fully catalytically treated.

A heterogeneous catalytic reactor as shown in Figure 1, the catalytic reactor includes a raw water chamber 3, the lower part of the raw water chamber is connected with a multi-layer purification reaction chamber 5, each layer of purification reaction chamber is provided with a water-passing plate above There are multiple water inlet channels 2 on the board, and the water inlet channels 2 are through holes with a diameter of 1 mm.

A filter layer 4 is provided on the water-passing plate, and the filter layer is made of activated carbon or ion exchange resin or both.

The bottom of the purification reaction chamber 5 and the water purification chamber 9 are communicated through a water outlet channel 1, which is a narrow gap with a height of 2 mm.

A catalyst 7 is arranged on the inner wall of the purification reaction chamber 5, the catalyst is a photocatalytic catalyst, and the catalyst coating is a titanium dioxide film. A catalytic generating device 6 is arranged inside the purification reaction chamber 5, and the catalytic generating device 6 is a light generating device, which can emit ultraviolet light. The light-generating device runs through the entire purification reaction chamber, and the emitted ultraviolet light oxidizes the photocatalytic catalyst on the micropores of the filter layer and the photocatalytic catalyst on the side wall of the purification reaction chamber, and disinfects the water flow between the light-generating device and the catalyst .

The side wall of the purification reaction chamber 5 is spiral or wavy, which can increase the coverage area of the catalyst and the contact area between the water flow and the catalyst.

A water inlet switch port and a power supply are provided on the top of the raw water chamber 3, the water inlet switch port is a flip-type water inlet cover, the power source is a rechargeable battery or a solar charging board, and the purification reaction chamber 5 is provided with suspended particles with photocatalyst attached to the surface. The ultraviolet light emitted by the light generating device oxidizes the suspended particles and further disinfects the water. A water outlet 8 is provided on the top or side of the water purification chamber 9. An electrode is provided on the outer wall of the purification reaction chamber 5 to form a counter electrode with the catalyst layer 7 on the inner wall of the purification reaction chamber 5.

Because the ultraviolet lamp passes through the raw water chamber 3 from top to bottom and through the purification reaction chamber 5, the raw water in the raw water chamber 3 is first partially irradiated by the ultraviolet lamp. This stage belongs to the ultraviolet lamp immersion disinfection. Due to the low oxygen content in the water, less ozone is produced in this process, and its disinfection effect is to destroy the DNA structure of bacteria. After pouring out part of the purified water each time, due to the structure of the connector, the water pressure on both sides of the closed air chamber is not balanced, the sequential batch continuous flow starts, and the UV lamp starts to work at this time. The water entering the filter layer will be adsorbed by activated carbon, and the formation and digestion of biological activated carbon will utilize the strong specific surface area of activated carbon for water purification. The bacteria existing in the water and the bacteria remaining in the activated carbon will eventually form a kind of biological activated carbon to biologically decompose the pollutants in the water. The water entering the filter layer exchanges anion and cation with the ion exchange resin, which can change the water quality.

After a certain period of use, the water that passes through the filter layer, that is, the carbonized water, will contain a certain amount of bacteria, but the chlorine and some heavy metals and calcium and magnesium ions it contains will be improved, the taste and color will also be improved, and the ammonia nitrogen content will be somewhat reduce. The ultraviolet lamp passing through the filter layer will irradiate the activated carbon and ion exchange resin. Due to the presence of air in the closed air chamber below the filter layer, ozone will be simultaneously generated under the irradiation of the ultraviolet lamp. Ozone and ultraviolet rays can generate hydroxyl radicals through photochemical reaction, which is a broad-spectrum oxidant that can revive saturated activated carbon. At the same time, activated carbon can catalyze the generation of hydroxyl radicals from ozone.

The filtered water is between the filter layer 4 and the purification chamber 9. Based on the surface tension of the water, the water film formed by the lower surface of the filter layer extends downward to the inner surface of the pipe. And the lower surface formed by the water surface encloses a closed air chamber. The water that slowly flows through the filter layer driven by the pressure difference is all attached to the inner surface of the tube and flows down in a thin layer. After the rising water surface contacts the lower end of the extension tube, a closed air chamber is formed, and the inside of the air chamber is empty. , There is only air, and the ultraviolet lamp coming through the filter layer is on the central axis of the air chamber. The phenomenon of water flowing along the thin layer of the arc-shaped inner wall just meets the surface disinfection requirements of ultraviolet rays, the requirements of increasing the contact efficiency required for photocatalysis, and the requirements of enhancing the photoelectrochemical reaction that will occur on the surface of photocatalysts such as titanium dioxide. The presence of air in the air chamber also provides the initial raw material for ultraviolet light to produce ozone. The surface of titanium dioxide irradiated by light will generate photo-generated carriers. In the presence of water, it will generate oxygen and strong oxidizing free radicals (hydroxyl free radicals, oxygen free radicals). It can also change the surface properties of the semiconductor film for affinity. The conversion of water and hydrophobicity can produce hydrogen after forming a suitable counter electrode structure.

Strong oxidizing substances will eventually oxidize organic pollutants into water and carbon dioxide, and reducing substances will reduce the remaining chlorine gas after activated carbon adsorption to HCL. This equipment uses ultraviolet radiation that can provide the most suitable photon energy to the photocatalyst, promotes the occurrence of high-efficiency photocatalytic reaction, and makes the surface of the gas chamber plated with the photocatalyst have a strong self-cleaning ability, and its strength is far greater than that of natural light. It is not only limited to the treatment of inorganic and organic impurities, decomposing E. coli endotoxin O157, but also killing and decomposing microorganisms and protozoa to prevent the occurrence of photoresurrection. As a general rule, in electromagnetic radiation, the more energy associated with each photon, the more dangerous it is to living organisms. Ultraviolet rays inactivate microorganisms by changing their DNA. DNA does not absorb light with wavelengths above 300 nanometers, and light with wavelengths below 200 nanometers cannot penetrate water. Ultraviolet rays have a very good disinfection effect on protozoa in the water without any secondary pollution.

Due to the poor penetration ability of ultraviolet rays in water, ultraviolet rays are mostly used for surface disinfection. The thin-layer flow phenomenon observed in the reactor of the present invention provides the possibility of achieving high disinfection effects with low-intensity ultraviolet rays. Ozone is the strongest chemical disinfectant. The oxidation potential of ozone is higher than that of chlorine and hydrogen peroxide. It is a bacteriolytic agent and kills viruses thoroughly. Ozone can be generated by irradiating the air with ultraviolet rays. Ozone and ultraviolet rays react photochemically to produce strong oxidizing products such as OH and free radicals. It is also highly oxidizing. The reaction that ozone directly participates in is called D reaction. Once ozone is dissolved in water, it begins to attenuate to generate hydroxyl radicals. The reaction that (HO·) free radicals participates in is called R reaction. As the main action of ozone as a disinfectant, it is through direct oxidation of ozone, so the ozone margin is also very important. The air contains about 21% oxygen. Oxygen generated on the surface of the titanium dioxide catalyzed by this device will continuously provide the closed air chamber to generate ozone. The ultraviolet light source introduced by this device not only has a powerful anti-virus wavelength of 253.7 nanometers, but also can generate ozone. Ozone and ultraviolet light have their own advantages in the disinfection process of water treatment. The half-life in water is short. Ozone has a very good disinfection effect on endospores, bacteria and viruses in the water. Ultraviolet rays and ozone can complement each other and the product has no side effects and no secondary pollution is the safest disinfection and sterilization process at present.

It is also possible to replace the light generating device with an electric generating device or an ultrasonic generating device or a thermal energy generating device or a chemical energy generating device or a microwave generating device or a biological energy generating device.
