The length of the dust removing electric field anode refers to the minimum length from one end to the other end of the working surface of the dust removing electric field anode.

in view of the unique properties of ionized dust removal, ionized dust removal may be suitable for removing particulate matter from a gas. However, through many years of researches of universities, research institutions and enterprises, the existing electric field dust removing device can only remove about 70% of particulate matters, and cannot meet the needs of many industries. In addition, the electric field dust removing device in the prior art is too large in size.
The present inventors have studied and found that the disadvantage of the electric field dust removing device in the prior art is caused by electric field coupling. The invention can obviously reduce the size (i.e. volume) of the electric field dust removing device by reducing the electric field coupling times. For example, the size of the ionization dust removing device provided by the invention is about one fifth of the size of the existing ionization dust removing device. The reason is that in order to obtain an acceptable particle removal rate, the gas flow rate is set to be about 1m/s in the existing ionization dust removing device, and the invention can still obtain a higher particle removal rate under the condition that the gas flow rate is increased to be 6 m/s. When treating a given flow of gas, the electric field dust collector may be reduced in size as the gas velocity increases.
In addition, the present invention can significantly improve particle removal efficiency. For example, the electric field dust removing device of the related art can remove about 70% of particulate matter in the exhaust gas of the engine at a gas flow rate of about 1m/s, but the present invention can remove about 99% of particulate matter even at a gas flow rate of 6 m/s.
The present invention has achieved the above unexpected results, since the inventors have found the effect of electric field coupling and have found a method of reducing the number of electric field coupling.
The ionised dust removal electric field between the dust removal electric field anode and the dust removal electric field cathode is also referred to as the first electric field. In an embodiment of the present invention, a second electric field that is not parallel to the first electric field is further formed between the dust-removing electric field anode and the dust-removing electric field cathode. In another embodiment of the present invention, the second electric field is not perpendicular to the flow channel of the ionization dust removing electric field. The second electric field, also called auxiliary electric field, may be formed by one or two first auxiliary electrodes, which may be placed at the inlet or outlet of the ionised dust removal electric field when the second electric field is formed by one first auxiliary electrode, which may be negatively or positively charged. When the first auxiliary electrode is a cathode, the first auxiliary electrode is arranged at or near an inlet of the ionization dust removal electric field; the first auxiliary electrode and the dust removing electric field anode have an included angle alpha, and alpha is more than or equal to 0 degree and less than or equal to 125 degrees, or alpha is more than or equal to 45 degrees and less than or equal to 125 degrees, or alpha is more than or equal to 60 degrees and less than or equal to 100 degrees, or alpha=90 degrees. When the first auxiliary electrode is an anode, the first auxiliary electrode is arranged at or near an outlet of the ionization dust removal electric field; the first auxiliary electrode and the dedusting electric field cathode have an included angle alpha, and alpha is more than or equal to 0 degree and less than or equal to 125 degrees, or alpha is more than or equal to 45 degrees and less than or equal to 125 degrees, or alpha is more than or equal to 60 degrees and less than or equal to 100 degrees, or alpha=90 degrees. When the second electric field is formed by two first auxiliary electrodes, one of the first auxiliary electrodes may be charged with a negative potential and the other first auxiliary electrode may be charged with a positive potential; one first auxiliary electrode may be placed at the inlet of the ionization electric field and the other first auxiliary electrode at the outlet of the ionization electric field. In addition, the first auxiliary electrode may be a part of the dust-removing electric field cathode or the dust-removing electric field anode, that is, the first auxiliary electrode may be formed by an extension of the dust-removing electric field cathode or the dust-removing electric field anode, where the lengths of the dust-removing electric field cathode and the dust-removing electric field anode are different. The first auxiliary electrode may also be a separate electrode, that is, the first auxiliary electrode may not be part of the dedusting electric field cathode or the dedusting electric field anode, and in this case, the voltage of the second electric field is different from the voltage of the first electric field and may be separately controlled according to the working condition.
The second electric field is capable of applying a force to the negatively charged oxygen ion stream between the dedusting field anode and the dedusting field cathode toward the outlet of the ionization electric field such that the negatively charged oxygen ion stream between the dedusting field anode and the dedusting field cathode has a velocity of movement toward the outlet. In the process that gas flows into an ionization electric field and flows towards the outlet direction of the ionization electric field, negatively charged oxygen ions move towards the anode of the dust removal electric field and towards the outlet direction of the ionization electric field, and the negatively charged oxygen ions are combined with particles in the gas in the process of moving towards the anode of the dust removal electric field and towards the outlet of the ionization electric field, as the oxygen ions have the moving speed towards the outlet, the oxygen ions cannot generate stronger collision when being combined with the particles, so that the stronger collision is avoided, the larger energy consumption is caused, the oxygen ions are ensured to be easily combined with the particles, the charged efficiency of the particles in the gas is higher, more particles can be collected under the action of the anode of the dust removal electric field, and the dust removal efficiency of the electric field device is ensured to be higher. The collection rate of the electric field device for particles entering the electric field along the ion flow direction is nearly doubled compared with that of particles entering the electric field along the counter ion flow direction, so that the dust accumulation efficiency of the electric field is improved, and the electric consumption of the electric field is reduced. In addition, the main reason that the dust collection efficiency of the dust collection electric field in the prior art is lower is that the direction of dust entering the electric field is opposite to or vertically crossed with the direction of ion flow in the electric field, so that the mutual collision of the dust and the ion flow is severe, larger energy consumption is generated, the charge efficiency is influenced, the dust collection efficiency of the electric field in the prior art is further reduced, and the energy consumption is increased. When the electric field device collects dust in the gas, the gas and the dust enter the electric field along the ion flow direction, the dust is charged fully, and the electric field consumption is small; the dust collection efficiency of the monopole electric field can reach 99.99 percent. When gas and dust enter an electric field in the reverse ion flow direction, the dust charge is insufficient, the electric consumption of the electric field is increased, and the dust collection efficiency is 40% -75%. In one embodiment of the invention, the ion flow formed by the electric field device is beneficial to fluid transportation, air intake oxygenation, heat exchange or the like of the unpowered fan.
Along with the continuous collection of particulate matters and the like in the inlet air by the dust removal electric field anode, the particulate matters and the like are accumulated on the dust removal electric field anode to form dust, and the dust thickness is continuously increased, so that the polar distance is reduced. In an embodiment of the present invention, when the electric field is deposited, the electric field device detects the electric field current and performs dust cleaning by any one of the following methods:
(1) When the electric field device detects that the electric field current increases to a given value, the electric field voltage is increased.
(2) When the electric field device detects that the electric field current is increased to a given value, the electric field back corona discharge phenomenon is utilized to finish dust cleaning.
(3) When the electric field device detects that the electric field current increases to a given value, the electric field back corona discharge phenomenon is utilized to increase the electric field voltage and limit the injection current, so that dust cleaning is completed.
(4) When the electric field device detects that the electric field current increases to a given value, the electric field back corona discharge phenomenon is utilized to increase the electric field voltage and limit the injection current, so that the rapid discharge at the carbon deposition position of the anode generates plasma, the plasma enables the dust organic components to be deeply oxidized, polymer bonds to be broken, and micromolecular carbon dioxide and water are formed, so that dust cleaning is completed.
In an embodiment of the present invention, the dust removing electric field anode and the dust removing electric field cathode are respectively electrically connected with two electrodes of the power supply. The voltages applied to the dedusting electric field anode and the dedusting electric field cathode need to be selected to be appropriate voltage levels, and the specific selection of the voltage levels depends on the volume, temperature resistance, dust holding rate and the like of the electric field device. For example, voltages from 1kv to 50kv; during design, firstly, considering temperature-resistant conditions, and parameters of polar distance and temperature: the dust accumulation area is larger than 0.1 square/kilocubic meter/hour, the electric field length is larger than 5 times of a single-tube inscribed circle, and the flow speed of the electric field airflow is controlled to be smaller than 9 meters/second. In one embodiment of the present invention, the dust removing electric field anode is formed by a first hollow anode tube and is honeycomb-shaped. The shape of the first hollow anode tube port may be circular or polygonal. In one embodiment of the invention, the value range of the inscribed circle of the first hollow anode tube is 5-400mm, the corresponding voltage is 0.1-120kv, and the corresponding current of the first hollow anode tube is 0.1-30A; different inscribed circles correspond to different corona voltages, about 1KV/1MM.
In an embodiment of the invention, the electric field device includes a first electric field stage, where the first electric field stage includes a plurality of first electric field generating units, and one or more first electric field generating units may be provided. The first electric field generating unit is also called a first dust collecting unit, and the first dust collecting unit comprises one or more of the dust collecting electric field anode and the dust collecting electric field cathode. When the first electric field level is multiple, the dust collection efficiency of the electric field device can be effectively improved. In the same first electric field stage, anodes of all the dust removing electric fields are of the same polarity, and cathodes of all the dust removing electric fields are of the same polarity. And when the number of the first electric field stages is multiple, the first electric field stages are connected in series. In an embodiment of the invention, the electric field device further includes a plurality of connection housings, and the first electric field stages connected in series are connected through the connection housings; the distance of the first electric field stage of adjacent two stages is greater than 1.4 times of the pole pitch.

Referring to fig. 1, a schematic structure of an air dust removal system in an embodiment is shown. The air dust removal system 101 includes an electric field device inlet 1011, a centrifugal separation mechanism 1012, a first water filtering mechanism 1013, an electric field device 1014, an insulation mechanism 1015, a wind homogenizing device, a second water filtering mechanism 1017, and/or an ozone mechanism 1018.

As shown in fig. 1, the electric field device inlet 1011 is disposed on the inlet wall of the centrifugal separation mechanism 1012 to receive gas with particulate matter.
The centrifugal separation mechanism 1012 provided at the lower end of the air dust removal system 101 is a conical cylinder. The junction of the cone and the electric field device 1014 is a vent with a first filter layer for filtering particulate matter disposed thereon. The bottom of the conical cylinder is provided with a powder outlet for receiving the particles.
Specifically, the particulate-containing gas will change from linear to circular motion as it enters the centrifugal separation mechanism 1012 from the electric field device inlet 1011, typically at a velocity of 12-30 m/s. The vast majority of the swirling air flow flows helically down the walls from the cylinder towards the cone. In addition, the particles are thrown against the inner wall of the separating mechanism by centrifugal force, and once the particles are contacted with the inner wall, the momentum of downward axial velocity near the inner wall falls along the wall surface and is discharged from the powder outlet. The descending outward airflow continuously flows into the center part of the separating mechanism during the descending process to form centripetal radial airflow, and the part of the airflow forms upward rotating inward airflow. The rotation directions of the inner and outer rotational flows are the same. Finally, the purified gas is discharged into the electric field device 1014 through a gas outlet and a first filter screen (not shown), and a part of the finer dust particles which are not separated cannot escape.

In this embodiment, the material to be treated may be granular dust, or other impurities to be treated.
In this embodiment, the dc power supply may be a dc high-voltage power supply. A discharge electric field, which is an electrostatic field, is formed between the dust-removing electric field cathode 5081 and the dust-removing electric field anode 5082. Without the auxiliary electrode 5083, the ion flow in the electric field between the dust-removing electric field cathode 5081 and the dust-removing electric field anode 5082 is in the direction perpendicular to the electrodes, and flows back and forth between the two electrodes, and causes the ion to be consumed back and forth between the electrodes. For this reason, the present embodiment uses the auxiliary electrode 5083 to shift the relative positions of the electrodes, so as to form a relative imbalance between the dedusting electric field anode 5082 and the dedusting electric field cathode 5081, and this imbalance deflects the ion flow in the electric field.

The electric field device has the advantages that the collection rate of the particles entering the electric field along the ion flow direction is nearly doubled compared with that of the particles entering the electric field along the counter ion flow direction, so that the dust accumulation efficiency of the electric field is improved, and the electric power consumption of the electric field is reduced. In addition, the main reason that the dust collection efficiency of the dust collection electric field in the prior art is lower is that the direction of dust entering the electric field is opposite to or vertically crossed with the direction of ion flow in the electric field, so that the mutual collision of the dust and the ion flow is severe, larger energy consumption is generated, the charge efficiency is influenced, the dust collection efficiency of the electric field in the prior art is further reduced, and the energy consumption is increased.
When the electric field device is used for collecting dust in gas, the gas and the dust enter an electric field along the ion flow direction, so that the dust is sufficiently charged, and the electric field consumption is small; the dust collection efficiency of the monopole electric field can reach 99.99 percent. When gas and dust enter an electric field in the reverse ion flow direction, the dust charge is insufficient, the electric consumption of the electric field is increased, and the dust collection efficiency is 40% -75%. In addition, the ion flow formed by the electric field device in the embodiment is beneficial to fluid transportation, oxygenation, heat exchange and the like of the unpowered fan.

Example 21
The air dust removal system of this embodiment includes the electric field device of the above-described embodiment 17, 18, 19, or 20.

Example 22 (front electrode)
As shown in fig. 16, the present embodiment provides an electric field device, which includes an electric field device inlet 3085, a flow channel 3086, an electric field flow channel 3087, and an electric field device outlet 3088, wherein the flow channel 3086 is provided with a front electrode 3083, the ratio of the cross-sectional area of the front electrode 3083 to the cross-sectional area of the flow channel 3086 is 99% to 10%, the electric field device further includes a dust removal electric field cathode 3081 and a dust removal electric field anode 3082, and the electric field flow channel 3087 is located between the dust removal electric field cathode 3081 and the dust removal electric field anode 3082. The working principle of the electric field device of the invention is as follows: the gas containing the pollutants enters the flow channel 3086 through the electric field device inlet 3085, the front electrode 3083 arranged in the flow channel 3086 conducts electrons to part of the pollutants, and part of the pollutants are charged, when the pollutants enter the electric field flow channel 3087 from the flow channel 3086, the dust removing electric field anode 3082 applies attractive force to the charged pollutants, the charged pollutants move to the dust removing electric field anode 3082 until the part of the pollutants are attached to the dust removing electric field anode 3082, meanwhile, an ionization dust removing electric field is formed between the dust removing electric field cathode 3081 and the dust removing electric field anode 3082 in the electric field flow channel 3087, the ionization dust removing electric field charges the other part of the pollutants, and therefore the other part of the pollutants are subjected to attractive force applied by the dust removing electric field anode 3082 after being charged and finally attached to the dust removing electric field anode 3082, so that the electric field device is used for enabling the charged efficiency of the pollutants to be higher, further guaranteeing that the dust removing electric field anode 3082 can collect more pollutants, and guaranteeing that the collecting efficiency of the pollutants is higher.
The cross-sectional area of the front electrode 3083 refers to the sum of the areas of the front electrode 3083 along the solid portion of the cross-section. The ratio of the cross-sectional area of the front electrode 3083 to the cross-sectional area of the flow passage 3086 may be 99% to 10%, or 90% to 10%, or 80% to 20%, or 70% to 30%, or 60% to 40%, or 50%.
As shown in fig. 16, in this embodiment, the front electrode 3083 and the dust removing electric field cathode 3081 are both electrically connected to the cathode of the dc power supply, and the dust removing electric field anode 3082 is electrically connected to the anode of the dc power supply. In this embodiment, the front electrode 3083 and the electric field cathode 3081 are both negative, and the electric field anode 3082 is positive.
As shown in fig. 16, the front electrode 3083 in this embodiment may be mesh-shaped. Thus, when the gas flows through the flow channel 3086, the gas and the pollutants are convenient to flow through the front electrode 3083 by utilizing the reticular structural characteristic of the front electrode 3083, and the pollutants in the gas are more fully contacted with the front electrode 3083, so that the front electrode 3083 can conduct electrons to more pollutants, and the charging efficiency of the pollutants is higher.
As shown in fig. 16, in this embodiment, the dust removing electric field anode 3082 is tubular, the dust removing electric field cathode 3081 is rod-shaped, and the dust removing electric field cathode 3081 is disposed in the dust removing electric field anode 3082. The electric field dust anode 3082 and the electric field dust cathode 3081 in this embodiment are asymmetric. When the gas flows into the ionization electric field formed between the dust field cathode 3081 and the dust field anode 3082, the contaminants are charged, and the charged contaminants are collected on the inner wall of the dust field anode 3082 by the attractive force applied by the dust field anode 3082.
In addition, as shown in fig. 16, in the present embodiment, the electric field dust anode 3082 and the electric field dust cathode 3081 both extend in the front-rear direction, and the front end of the electric field dust anode 3082 is located forward of the front end of the electric field dust cathode 3081 in the front-rear direction. And as shown in fig. 16, the rear end of the electric field dust anode 3082 is located rearward of the rear end of the electric field dust cathode 3081 in the front-rear direction. In this embodiment, the length of the electric field anode 3082 is longer along the front-rear direction, so that the area of the adsorption surface on the inner wall of the electric field anode 3082 is larger, so that the attraction to the contaminants with negative potential is larger, and more contaminants can be collected.
As shown in fig. 16, in this embodiment, the electric field cathode 3081 and the electric field anode 3082 form ionization units, and there are a plurality of ionization units, so that more contaminants can be collected by using a plurality of ionization units, and the electric field device has stronger capability of collecting contaminants and higher collection efficiency.
In this embodiment, the contaminants include general dust with weak conductivity, metal dust with strong conductivity, mist droplets, aerosol, and the like. In this embodiment, the electric field device is used for collecting common dust with weak conductivity and pollutants with strong conductivity in gas, and the collecting process is as follows: when the gas flows into the flow channel 3086 through the electric field device inlet 3085, the pollutants such as metal dust, fog drops or aerosol with stronger conductivity in the gas are directly negatively charged when contacting with the front electrode 3083 or reaching a certain range with the front electrode 3083, then all the pollutants enter the electric field flow channel 3087 along with the gas flow, the dust removing electric field anode 3082 applies attractive force to the negatively charged metal dust, fog drops or aerosol and collects part of the pollutants, meanwhile, the dust removing electric field anode 3082 and the dust removing electric field cathode 3081 form an ionization electric field, oxygen ions are obtained through oxygen in the ionization gas by the ionization electric field, and after the negatively charged oxygen ions are combined with common dust, the common dust is negatively charged, the dust removing electric field anode 3082 applies attractive force to the part of the negatively charged dust and collects the part of the pollutants, so that the pollutants with stronger conductivity and weaker conductivity in the gas are collected, the electric field device can collect the types of substances more widely, and has stronger collection capacity.
The dust removing electric field cathode 3081 described above in this embodiment is also referred to as a corona charging electrode. The direct current power supply is specifically a direct current high voltage power supply. Direct-current high voltage is introduced between the front electrode 3083 and the dust removal electric field anode 3082 to form a conductive loop; direct-current high voltage is introduced between the dust removal electric field cathode 3081 and the dust removal electric field anode 3082 to form an ionization discharge corona electric field. The front electrode 3083 in this embodiment is a densely distributed conductor. When the dust easy to be charged passes through the front electrode 3083, the front electrode 3083 directly charges electrons to the dust, and the dust is then adsorbed by the anode 3082 of the dedusting electric field with different poles; meanwhile, uncharged dust passes through an ionization region formed by the dedusting electric field cathode 3081 and the dedusting electric field anode 3082, and ionized oxygen formed by the ionization region can charge electrons to the dust, so that the dust is continuously charged and adsorbed by the dedusting electric field anode 3082 with different poles.
In this embodiment, the electric field device can form two or more power-on modes. For example, in the case of sufficient oxygen in the gas, the pollutants can be charged by using an ionization discharge corona electric field formed between the dust removal electric field cathode 3081 and the dust removal electric field anode 3082 to ionize the oxygen, and then the pollutants are collected by using the dust removal electric field anode 3082; and when the oxygen content in the gas is too low, or the gas is in an oxygen-free state, or the pollutant is conductive dust fog, the front electrode 3083 is used for directly electrifying the pollutant, so that the pollutant is adsorbed by the dust removal electric field anode 3082 after being fully electrified. The electric fields of the two charging modes can be adopted in the embodiment, so that high-resistance dust easy to charge and low-resistance metal dust, aerosol, liquid mist and the like easy to charge can be collected simultaneously. The two power-on modes are used simultaneously, and the application range of the electric field is enlarged.
