The electric field device provided by the present invention can be applied to the field of gas dust removal technology, such as electrostatic dust removal devices, and can also be used as plasma generators (fluorescent lamps), ozone generators and other devices that require electric field participation.

The following takes the electric field device provided by the present invention as an electrostatic precipitator as an example for implementation and description, and the structure of the electrostatic precipitator is the same as the structure of the above electric field device:

At present, an electric field device is also used to remove dust and purify the particles contained in the dust-containing gas. The basic principle is to use high-voltage discharge to generate plasma to charge the particles, and then adsorb the charged particles to the dust collecting electrode to achieve electric field dust removal. However, the existing electrostatic precipitator has problems such as large space occupation, high energy consumption, and low processing efficiency.

The electric field device provided by the present invention is small in size and low in energy consumption, and can be applied to the technical field of gas dust removal. Some embodiments can effectively remove particulate matter in the gas.

In an embodiment of the present invention, the electric field device may include an electric field cathode and an electric field anode, and an ionizing electric field is formed between the electric field cathode and the electric field anode. When the gas enters the ionization electric field, the oxygen in the gas will be ionized to form a large number of charged oxygen ions. The oxygen ions combine with dust and other particles in the gas to charge the particles. The electric field anode exerts an adsorption force on the negatively charged particles. The particles are adsorbed on the anode of the electric field to remove the particles in the gas.

In an embodiment of the present invention, the electric field anode may include one or more hollow anode tubes arranged in parallel. When there are multiple hollow anode tubes, all the hollow anode tubes constitute a honeycomb electric field anode. In an embodiment of the present invention, the cross section of the hollow anode tube may be circular or polygonal. If the cross section of the hollow anode tube is circular, a uniform electric field can be formed between the electric field anode and the electric field cathode, and the inner wall of the hollow anode tube is not easy to accumulate dust. If the hollow anode tube has a triangular cross-section, 3 dust accumulation surfaces and 3 remote dust-holding angles can be formed on the inner wall of the hollow anode tube. The hollow anode tube with this structure has the highest dust holding rate. If the cross section of the hollow anode tube is quadrilateral, 4 dust accumulation surfaces and 4 dust holding angles can be obtained, but the assembly structure is unstable. If the cross section of the hollow anode tube is hexagonal, 6 dust accumulation surfaces and 6 dust retention angles can be formed, and the dust accumulation surface and the dust retention rate reach a balance. If the cross section of the hollow anode tube is more polygonal, more dust accumulation edges can be obtained, but the dust holding rate is lost.

In one embodiment of the present invention, the insulation mechanism is arranged outside the electric field flow channel, that is, outside the electric field flow channel, to prevent or reduce dust in the gas from gathering on the insulation mechanism, causing the insulation mechanism to break down or conduct electricity.

In an embodiment of the present invention, the first anode part is located in front of the cathode support plate and the insulating mechanism in the gas flow direction. The first anode part can remove water in the gas and prevent water from entering the insulating mechanism, causing short circuit and ignition of the insulating mechanism. . In addition, the first anode part can remove a considerable part of the dust in the gas. When the gas passes through the insulating mechanism, a considerable part of the dust has been eliminated, reducing the possibility of short-circuiting of the insulating mechanism caused by the dust. In an embodiment of the present invention, the insulating mechanism includes insulating ceramic pillars. The design of the first anode part is mainly to protect the insulating ceramic pillars from being polluted by particles in the gas. Once the insulating ceramic pillars are polluted by the gas, the electric field anode and the electric field cathode will be connected, which will invalidate the dust accumulation function of the electric field anode. The design of an anode part can effectively reduce the pollution of the insulating ceramic pillar and increase the use time of the product. In the process of gas flowing through the electric field channel, the first anode part and the electric field cathode first contact the polluting gas, and the insulating mechanism contacts the gas to achieve the purpose of first removing dust and then passing through the insulating mechanism, reducing pollution to the insulating mechanism and extending The cleaning and maintenance cycle corresponds to the insulating support of the electrode after use. The length of the first anode part is long enough to remove some dust, reduce dust accumulated on the insulation mechanism and the cathode support plate, and reduce electric breakdown caused by the dust.

The existing industrial electrostatic dust collection electric field is composed of a dust collecting electrode and a discharge electrode. Each electrode of the electric field is composed of an electrode plate, which is arranged in parallel to each electrode of the electric field, and the electrode has the opposite adsorption force to the charged dust. However, when the charge is negative, it is adsorbed by the positive electrode, and when the charge is positive, it is adsorbed by the negative plate. But after adsorption, the chargeability is reversed and tends to be the same as the electrode plate, that is, the dust on the positive electrode plate will again tend to the negative electrode, and the dust on the negative electrode plate will tend to the positive electrode. This movement and force are repeated endlessly, forming Electric field coupling consumption. The coupling consumption of the electric field causes the efficiency of electrostatic adsorption of particles with weak adhesion and liquid mist to decline or fail. Therefore, the dust collection efficiency is low and the energy consumption is high.

The inventor of the present invention has discovered through research that the disadvantages of poor removal efficiency and high energy consumption of existing electric field devices are caused by electric field coupling. The invention can significantly reduce the size (ie volume) of the electric field dust removal device by reducing the number of electric field couplings. For example, when the electric field device provided by the present invention is applied to electrostatic dust removal, the size of the electric field dust removal device of the present invention is about one-fifth the size of the existing ionization dust removal device. The reason is that in order to obtain an acceptable particle removal rate, the gas flow rate in the existing electric field dust removal device is set to about 1m/s, while the present invention can still obtain a higher gas flow rate when the gas flow rate is increased to 6m/s. Particle removal rate. When processing a given flow of gas, as the gas velocity increases, the size of the electric field dust removal device can be reduced.

In addition, the present invention can significantly improve the particle removal efficiency. For example, when the gas flow rate is about 1m/s, the prior art electric field dust removal device can remove about 70% of the particulate matter in the engine exhaust, but the present invention can remove about 99% of the particulate matter, even when the gas flow rate is 6m/s .

Since the inventor discovered the effect of electric field coupling and found a method to reduce the number of times of electric field coupling, the present invention achieved the above unexpected results.

Generally, the dust removal efficiency of the electrostatic dust collection electric field is usually low, and the energy consumption is high. In order to solve problems such as low dust collection efficiency, the dust collection electric field in the prior art often selects multiple stages in series to improve the overall dust collection efficiency. Such a series connection of multiple electric fields will cause the dust collector to occupy a larger space and consume higher energy consumption, and the dust removal efficiency of a single electric field is still substantially low.

In an embodiment of the present invention, the electric field device includes an auxiliary electric field that is not parallel to the electric field anode and the electric field cathode.

In an embodiment of the present invention, the electric field device further includes an auxiliary electric field, the ionization electric field includes a flow channel, and the auxiliary electric field is not perpendicular to the flow channel.

In an embodiment of the present invention, the auxiliary electric field exerts a backward force on the negatively charged oxygen ion flow between the electric field anode and the electric field cathode, so that the negatively charged oxygen ion flow between the electric field anode and the electric field cathode has a backward movement speed. When the gas containing the substance to be treated flows into the flow channel of the ionization electric field from front to back, the negatively charged oxygen ions will be combined with the substance to be treated in the process of moving to the anode of the electric field and backward, because the oxygen ions move backwards Speed, when the oxygen ions are combined with the substance to be treated, there will be no strong collision between the two, so as to avoid large energy consumption due to the strong collision, making the oxygen ions easy to combine with the substance to be treated, and The charging efficiency of the substance to be treated in the gas is higher, and more substances to be treated can be collected under the action of the electric field anode, and the dust removal efficiency of the electric field device provided by the present invention is higher.

In the application of electric field, it is often encountered that the dust is not fully charged due to the low oxygen content, and the dust is an easily conductive substance, and it is easy to lose electrons after being charged. These phenomena directly lead to the failure of electric field dust collection. In order to avoid such things from happening, it is generally believed that the dust removal electric field cannot be applied to the exhaust gas with thin oxygen and the low resistance dust that cannot be successfully charged. For example, the oxygen content in the exhaust gas of an oxygen-exhausted car is extremely low, the lowest is only 0.3%, and it can be ionized almost without oxygen, so oxygen ions cannot be produced, electrons cannot be transferred, and dust cannot be charged. In addition, for water mist and metal dust, they are easy to charge and lose electricity. After using oxygen ionization, they will soon fail, and the electric field cannot collect such dust. In addition, the electrostatic dust collection electric field in the prior art has a low collection efficiency for dust waiting to be processed.

In one embodiment of the present invention, one or more through holes are provided on the front electrode, and when gas passes through the through holes on the front electrode, the particles in the gas are charged. In the present invention, when the gas with particles passes through the through holes on the front electrode, the gas with particles passes through the front electrode, which increases the contact area between the gas with particles and the front electrode and increases the charging efficiency. The through hole on the front electrode in the present invention is any hole that allows substances to flow through the front electrode.

In an embodiment of the present invention, during operation, before the gas with pollutants enters the ionizing electric field formed by the electric field anode and the electric field cathode, and the gas with particles passes through the front electrode, the front electrode charges the particles in the gas . When the gas with particles enters the ionization electric field, the electric field anode exerts an attractive force on the charged particles, causing the charged particles to move toward the electric field anode until the charged particles adhere to the electric field anode.

In an embodiment of the present invention, the front electrode introduces electrons into the particles in the gas, and the electrons are transferred between the front electrode and the electric field anode, so that more particles in the gas are charged.

In an embodiment of the present invention, the charged particles conduct electrons between the front electrode and the electric field anode and form a current.

In an embodiment of the present invention, the front electrode charges the particulate matter in the gas by contacting the particulate matter in the gas. In an embodiment of the present invention, the front electrode transfers electrons to the particulate matter in the gas by contacting the particulate matter in the gas, and charges the particulate matter in the gas.

Normally, the gas temperature resistance of the electrostatic field is 200℃. If the temperature exceeds 200℃, it will cause electric field breakdown, especially the miniaturized and high-efficiency electric field. The electric field length of the honeycomb tube bundle is 400mm and the diameter is 300mm. Below 90°C, the dust collection efficiency of this electric field reaches 99%, but when the temperature rises to 120°C, the electric field will break down and cause intermittent failures, causing the dust collection efficiency to drop significantly below 50%. In the prior art, the method for solving the high temperature resistance of the electric field is usually to increase the distance between the electric field anode and the electric field cathode, increase the length of the electric field anode and the electric field cathode, and prevent the electric field from breakdown. The present invention proposes to reduce the length of the electric field anode and the electric field cathode. That is to shorten the length of the electric field anode and the electric field cathode: the length of the electric field anode is 1-9cm, and the length of the electric field cathode is 1-9cm, which solves the problem of high temperature resistance of the electric field generating unit and the electric field device. Obviously, the existing technology gives the opposite technical enlightenment. The present invention overcomes technical prejudice (increasing the distance between the electric field anode and the electric field cathode, and increasing the length of the electric field anode and the electric field cathode), and adopts the technical means that people discard due to technical prejudice, thereby solving the technology to be solved by the present invention problem.

Furthermore, the present invention proposes to reduce the length of the electric field anode and the electric field cathode, that is, to shorten the length of the electric field anode and the electric field cathode: the length of the electric field anode is 1-9cm, and the length of the electric field cathode is 1-9cm. When the dust enters at 200°C, due to the residence time Short, there are few opportunities for active molecules to connect in series, and no breakdown current can be formed. At the same time, the short circuit deformation caused by the thermal deformation of the electric field is reduced due to the short, and it is less likely to cause breakdown. The resistance temperature of the electric field device can reach 500℃ or even greater than 500℃ , And the dust collection efficiency is as high as 50%, that is, the electric field generating unit and the electric field device of the present application have both high temperature tolerance and high dust collection efficiency. Compared with the prior art, the technical effect of the present application produces For those skilled in the art, it cannot be predicted or inferred in advance. This application has achieved unexpected technical effects. When the invention produces unexpected technical effects, on the one hand, it shows that the invention has made significant progress. It also reflects that the technical solution of the invention is not obvious.

In some embodiments of the present invention, when the electric field temperature is 200°C, the corresponding dust collection efficiency is 99.9%; when the electric field temperature is 400°C, the corresponding dust collection efficiency is 90%; when the electric field temperature is 500°C, the corresponding dust collection efficiency is The dust collection efficiency is 50%.

In this way, an auxiliary electric field is formed between the auxiliary electrode 5083 and the electric field cathode 5081.

The electric field device provided in this embodiment can be used to remove particulate matter in the air. The auxiliary electric field described above exerts a backward force on the negatively charged oxygen ion flow between the electric field anode 5082 and the electric field cathode 5081. When the gas containing the substance to be treated flows into the anode tube 5084 from front to back, the negatively charged oxygen ions will combine with the substance to be treated in the process of moving to the electric field anode 5082 and backward, because the oxygen ions have a backward moving speed When the oxygen ions are combined with the substance to be treated, there will be no strong collision between the two, thereby avoiding large energy consumption due to the strong collision, making the oxygen ions easy to combine with the substance to be treated, and making The charging efficiency of the substances to be treated in the gas is higher, and furthermore, under the action of the electric field anode 5082 and the anode tube 5084, more substances to be treated can be collected, ensuring higher dust removal efficiency of the electric field device.

In addition, as shown in FIG. 6, there is an angle α between the rear end of the anode tube 5084 and the rear end of the electric field cathode 5081 in this embodiment, and 0°<α≤125°, or 45°≤α≤125°, Or 60°≤α≤100°, or α=90°.

The DC power supply in this embodiment may specifically be a DC high voltage power supply. A discharge electric field is formed between the electric field cathode 5081 and the electric field anode 5082, and the discharge electric field is an electrostatic field. Without the auxiliary electrode 5083, the ions flow in the electric field between the electric field cathode 5081 and the electric field anode 5082 along the direction perpendicular to the electrodes, and flow back and forth between the two electrodes, causing the ions to be folded back and forth between the electrodes for consumption. For this reason, in this embodiment, the auxiliary electrode 5083 is used to stagger the relative positions of the electrodes to form a relative imbalance between the electric field anode 5082 and the electric field cathode 5081. This imbalance will deflect the ion current in the electric field. In this electric field device, an auxiliary electrode 5083 is used to form an electric field capable of directional ion flow. The collection rate of the electric field device for particles entering the electric field in the direction of ion flow is nearly double that of particles entering the electric field in the direction of counter ion flow, thereby improving the efficiency of electric field dust accumulation and reducing electric field power consumption. In addition, the main reason for the low dust removal efficiency of the dust collecting electric field in the prior art is that the direction of the dust entering the electric field is opposite or perpendicular to the direction of the ion flow in the electric field, which causes the dust and the ion flow to collide violently with each other and produce large energy consumption. It also affects the charging efficiency, thereby reducing the electric field dust collection efficiency in the prior art and increasing the energy consumption.

When the electric field device in this embodiment is used to collect dust in the gas, the gas and dust enter the electric field along the direction of the ion flow, the dust is fully charged, and the electric field consumption is small; the dust collection efficiency of the unipolar electric field can reach more than 99.99%. When the gas and dust enter the electric field against the direction of ion flow, the dust is not fully charged, the electric power consumption of the electric field will increase, and the dust collection efficiency will be 40%-75%. In addition, the ion flow formed by the electric field device in this embodiment is beneficial to the unpowered fan fluid transportation, oxygenation, heat exchange, etc.

In this embodiment, the front electrode 3083 is a densely distributed conductor. When the easily charged dust and other particles pass through the front electrode 3083, the front electrode 3083 directly charges the particles with electrons, and the particles are then adsorbed by the electric field anode 3082 of the opposite electrode; at the same time, the uncharged particles pass the electric field cathode 3081 and the electric field anode 3082. The formed ionization zone, the ionized oxygen formed in the ionization zone will charge the electrons to the particles, so that the particles continue to be charged and absorbed by the electric field anode 3082 of the opposite electrode.
