Description

Technical Field

[0001] The technology of treating gas using a grid structure is an air purification technology and belongs to the field related to environment and health. Background Art

[0002] Electrostatic precipitators are often used in the fields of energy, environmental protection, and purification. Ozone is often used in the fields of water purification, medical treatment, and food and medicine. Electrodes and electric fields are used in electrostatic precipitators and ozone disinfection technologies and equipment. Electrostatic dust accumulation efficiency and ozone production efficiency are important indicators of these two technologies. The electrode and electric field structure are the core factors affecting the efficiency of electrostatic dust accumulation and ozone production. The positive and negative electrode forms of the electrostatic field include plate-plate structure, plate=wire structure, barrel-wire structure, and barrel-point structure. These structural changes are all for improving the efficiency of the electric field; the electric field forms of the ozone generator include tube, plate, and needle structures. The purpose of these structural changes is to reduce energy consumption and heat and increase the amount of ozone generated. Even careful selection is made on the electrode materials of the electrostatic field and ozone in order to further improve efficiency. However, the dust accumulation electric field efficiency does not exceed 90%, and the energy consumption of the ozone generator is higher than 8kw / kg. If a more efficient electrode is used to establish a perfect electric field, the dust accumulation efficiency and ozone emission can be greatly improved, achieving energy saving and consumption reduction while improving efficiency. Summary of the invention

[0003] The content of the present invention is to use the grid structure to process gas technology, using a porous, mesh structure grid as an anode, and forming an axial gas processing device relative to the cathode. By controlling the voltage and distance between the cathode and the grid to establish a unidirectional accelerating electric field, the processed gas passes through the grid axially from the cathode, and the particles, aerosols, and viruses in the gas are adsorbed, realizing a unidirectional electric field integrating the anode and the grid, and improving the dust accumulation efficiency. Using two grids and the cathode to establish an accelerating electric field in opposite directions, oxygen, carbon monoxide, carbon dioxide, hydrogen sulfide, and organic volatile gases will be repeatedly accelerated by the electric field, and the ionized gas is constrained by the direction of the accelerating electric field to achieve the purpose of full ionization and deep oxidation reaction, thereby controlling the amount of ozone and the oxidation reaction time.

[0004] Figure 1 The flow chart of using the gate to establish an axial accelerating electric field is as follows: Figure 11 is the cathode, 2 is the grid, 3 is the air, 4 is the charged substance, and 5 is the pure air. The cathode 1 is connected to the negative pole of the DC high voltage; the grid 2 is connected to the positive pole of the DC high voltage. The distance between the cathode and the grid is proportional to the voltage level of the DC high voltage. When the DC high voltage is connected to the air, current flows and begins to ionize the air 3, it means that a unidirectional accelerating electric field pointing from the cathode to the grid is established. When the air 3 flows from the cathode to the grid, the small molecule gas in the air will carry electrons and transfer electrons to other substances to form charged substances 4. The charged substances will be adsorbed by the positively charged grid 2. Since the grid is a porous, mesh structure, the unadsorbed uncharged gas will pass through the grid to form pure air 5 for discharge. The unidirectional accelerating electric field grid of this structure is a breathable structure and is placed in front of the air flow. The treated gas passes through the grid, which is not the traditional electrostatic field dust anode placed on the side of the air flow, and the treated gas flows from the side of the anode. Doing so solves two problems: it allows the charged material to fully contact the opposite electrode, which shortens the adsorption process and maximizes the probability of dust and opposite electrode contact, thereby improving efficiency; it also forces the charged material to flow in one direction with the air, preventing it from repeatedly ionizing, producing ozone, and not consuming heat or energy due to repeated ionization.

[0005] Figure 2 The flowchart of using two grids and cathode to establish an accelerating electric field in opposite directions is: Figure 2 1 is the cathode, 2 is the grid, 3 is the treated gas, 4 is another grid, 5 is the charged gas, 6 is the charged substance, and 7 is the treated gas. Cathode 1 is connected to the negative pole of the DC high voltage; grids 2 and 4 are connected to the positive pole of the DC high voltage. The distance between the cathode and the two grids is equal, and the distance between the cathode and the grid is proportional to the DC high voltage level. When the DC high voltage is connected to the gas, current flows through and begins to ionize gas 3, it means that a bidirectional accelerating electric field pointing from the cathode to the grid is established. When gas 3 flows in from one side of the grid, small molecules in the gas will carry electrons and transfer electrons to other substances to form charged gas 5 and charged substance 6. The charged substance will be adsorbed by the positively charged grid 2, and the charged gas 5 will also be repeatedly coupled by the grids on both sides until an oxidation reaction occurs and coupling heat is generated. For example, oxygen ions will react with oxygen to generate ozone. Since the grid is a porous, mesh structure, the unadsorbed uncharged gas will pass through the grid to form the treated gas 7 for discharge. The bidirectional accelerating electric field of this structure is to induce repeated coupling oscillation of ions, treat the gas and transfer heat. When oxygen passes through the double gate, it will be repeatedly ionized to produce ozone, and when carbon monoxide passes through the double gate, it will be oxidized and reduced.

[0006] Figure 3 The flow chart of using the grid composite electret and the cathode to establish a unidirectional accelerating electric field: Figure 31 is the cathode, 2 is the grid, 3 is the polluted gas, 4 is the electret, 5 is the charged substance, 6 is the charged gas, and 7 is the clean gas. The cathode 1 is connected to the negative pole of the DC high voltage; the grid 2 is connected to the positive pole of the DC high voltage. The distance between the cathode and the grid is proportional to the voltage level of the DC high voltage, and the grid and the electret 4 are close. When the DC high voltage is connected to the gas, the current flows and begins to ionize the gas 3, which means that a unidirectional accelerating electric field pointing from the cathode to the grid is established. When the gas 3 flows in from the cathode direction, the small molecules in the gas will carry electrons and transfer electrons to other substances, forming charged substances 5 and charged gas 6. The charged substance 5 will be adsorbed by the positively charged grid 2, and the charged gas 6 will release electrons to the electret 4 when it is close to the grid, until a denser micro-electric field is established in a smaller space inside the electret. Substances with large loads and small particle sizes in the polluted gas, such as airborne viruses and nano-level particles, will be adsorbed by the micro-electret electric field. Improve the adsorption efficiency of the entire electric field to more than 99.9999%. After treatment, the clean gas 7 is discharged. Achieve the purpose of continuous electret and high-efficiency filtration, and solve technical problems in nanochip manufacturing and virus prevention.

[0007] Example 1, manufacture of high temperature resistant EFFU. Use 0.2 mm diameter tungsten wire with an interval of 10 mm on the insulating frame as the cathode, and use 1.5 mm thick nickel foam as the grid, evenly laid on the insulating bracket. With a spacing of 10 mm, 6-10kv high voltage direct current is connected between the grid and the cathode, and the current is controlled below 3-30 mA / m2. When the power is turned on, air will enter from the cathode side and flow out from the grid, and the outflowing gas is dust-free clean air. Due to the use of ceramic insulating frame and nickel foam grid, the device can withstand a temperature of more than 500 degrees Celsius, and is used for air treatment in lithography machines, grinders, operating rooms, biopharmaceutical workshops, vehicles, ships, and airplanes.

[0008] Embodiment 2, used for purifying gas. Use 0.3 mm diameter tungsten wires with an interval of about 10 mm and arrange them on the insulating frame as cathodes, and use 1.5 mm thick nickel foam as grids, which are laid on both sides of the insulating bracket. The spacing is about 10 mm, and 6-12 kV high voltage direct current is connected between the grid and the cathode, and the current is controlled at about 15-50 mA / square meter. When the power is turned on, the gas enters from the grid on one side and flows out from the grid on the other side. When oxygen flows in, ozone flows out to manufacture an ozone generator; when odor flows out, odorless gas flows out to manufacture a deodorizer; when formaldehyde flows in, carbon dioxide flows out to manufacture a purifier; when bacteria and virus-containing gases flow in, pure air flows out, which is used to manufacture a sterilizer.

Use 0.02 mm diameter titanium wire with an interval of 1-3 mm and arrange it on the insulating skeleton as the cathode, use 0.2 mm thick 120 mesh stainless steel mesh as the grid, and composite polytetrafluoroethylene cotton as the electret to form a composite electrode on the grid, and the composite electrode is evenly laid on the insulating bracket. The spacing between the cathode and the cathode is 1-3 mm, and 0.8-3kv high-voltage direct current is connected between the composite grid and the cathode, and the current is controlled below 0.1-0.3 mA / square decimeter. Use a micro battery to power the high-voltage circuit. When worn, the cathode faces outward. When the power is turned on, oxygen-containing ion air will enter from the cathode side and flow out from the composite grid, and the outflowing gas is dust-free clean air. The exhaled gas will flow out to the cathode through the composite grid and further ionize. Continuous electret and two-way purification are achieved. Eliminate air pollution and virus transmission.
