In an embodiment of the invention, the insulating portion may also be in a tower shape.
In an embodiment of the present invention, a heating rod is disposed in the insulating portion, and when the ambient temperature of the insulating portion approaches the dew point, the heating rod is activated to perform heating. Because the inside and outside of the insulating part have temperature difference during use, condensation is easily generated inside and outside the insulating part. The outer surface of the insulation may be heated spontaneously or by gas to generate high temperature, which requires necessary insulation protection and scalding prevention. The heat insulation part comprises a protective enclosure baffle positioned outside the heat insulation part and a denitration purification reaction cavity.

in view of the specific performance of the ionized dust removal, the ionized dust removal can be suitable for removing the particulate matters in the gas. However, through many years of research of universities, research institutions and enterprises, the existing electric field dust removal device can only remove about 70% of particulate matters, and cannot meet the requirements of many industries. In addition, the electric field dust removal device in the prior art is too large in size.
The inventor of the present invention has 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 (namely the volume) of the electric field dust removal device by reducing the coupling times of the electric field. For example, the size of the ionization dust removal device provided by the invention is about one fifth of the size of the existing ionization dust removal device. The reason is that the gas flow rate is set to be about 1m/s in the existing ionized dust removing device in order to obtain acceptable particle removal rate, but the invention can still obtain higher particle removal rate under the condition of increasing the gas flow rate to 6 m/s. When a given flow of gas is treated, the size of the electric field dust collector can be reduced as the gas velocity is increased.
In addition, the present invention can significantly improve particle removal efficiency. For example, the prior art electric field dust removing device can remove about 70% of the particulate matter in the engine exhaust gas at a gas flow rate of about 1m/s, but the present invention can remove about 99% of the particulate matter even at a gas flow rate of 6 m/s.
The present invention achieves the above-noted unexpected results as the inventors have discovered the effect of electric field coupling and have found a way to reduce the number of electric field couplings.
The ionization dust-removing electric field between the anode of the air inlet dust-removing electric field and the cathode of the air inlet dust-removing electric field is also called as a first electric field. In an embodiment of the invention, a second electric field which is not parallel to the first electric field is formed between the anode of the air inlet dust removing electric field and the cathode of the air inlet dust removing electric field. 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, can be formed by one or two first auxiliary electrodes, which can be placed at the inlet or outlet of the ionizing dusting electric field when the second electric field is formed by one first auxiliary electrode, which can be charged at a negative potential, or at a positive potential. When the first auxiliary electrode is a cathode, the first auxiliary electrode is arranged at or close to an inlet of the ionization dust removal electric field; the first auxiliary electrode and the anode of the air inlet dust removal electric field form an included angle alpha, and the alpha is more than 0 degrees and less than or equal to 125 degrees, or more than or equal to 45 degrees and less than or equal to 125 degrees, or more than or equal to 60 degrees and less than or equal to 100 degrees, or more than or equal to 90 degrees. When the first auxiliary electrode is an anode, the first auxiliary electrode is arranged at or close to an outlet of the ionization dust removal electric field; the first auxiliary electrode and the cathode of the air inlet dust removal electric field form an included angle alpha, and the alpha is more than 0 degrees and less than or equal to 125 degrees, or the alpha is more than or equal to 45 degrees and less than or equal to 125 degrees, or the alpha is more than or equal to 60 degrees and less than or equal to 100 degrees, or the alpha is 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 entrance of the ionizing electric field and the other first auxiliary electrode at the exit of the ionizing electric field. In addition, the first auxiliary electrode may be a part of the cathode of the air intake dust removal electric field or the anode of the air intake dust removal electric field, that is, the first auxiliary electrode may be formed by the cathode of the air intake dust removal electric field or an extension section of the anode of the air intake dust removal electric field, and the length of the cathode of the air intake dust removal electric field is different from that of the anode of the air intake dust removal electric field. The first auxiliary electrode may also be a single electrode, that is, the first auxiliary electrode may not be a part of the cathode of the air intake dust removal electric field or the anode of the air intake dust removal electric field, and in this case, the voltage of the second electric field is different from the voltage of the first electric field, and may be controlled individually according to the operating condition.
The second electric field can apply a force towards the outlet of the ionization electric field to the negatively charged oxygen ion flow between the anode of the air inlet dust removal electric field and the cathode of the air inlet dust removal electric field, so that the negatively charged oxygen ion flow between the anode of the air inlet dust removal electric field and the cathode of the air inlet dust removal electric field has a moving speed towards the outlet. In the process of flowing in the gas into the ionization electric field and towards the outlet direction of the ionization electric field, the oxygen ions with negative charges move towards the anode of the gas inlet dust removal electric field and towards the outlet direction of the ionization electric field, and the oxygen ions with negative charges combine with particles in the gas in the process of moving towards the anode of the gas inlet dust removal electric field and towards the outlet of the ionization electric field, because the oxygen ions have the moving speed towards the outlet, the oxygen ions do not generate strong collision when combining with the particles, thereby avoiding larger energy consumption caused by the strong collision, ensuring that the oxygen ions are easily combined with the particles, and ensuring that the charging efficiency of the particles in the gas is higher, further collecting more particles under the action of the anode of the gas inlet dust removal electric field, and ensuring that the dust removal efficiency of the gas inlet electric field device is higher. The collection rate of the air inlet electric field device for the particulate matters entering the electric field along the ion flow direction is nearly doubled compared with the collection rate of the particulate matters entering the electric field along the reverse ion flow direction, so that the dust deposition efficiency of the electric field is improved, and the 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 low is that the direction of dust entering the electric field is opposite to or perpendicular to the direction of ion flow in the electric field, so that the dust and the ion flow collide violently with each other and generate large energy consumption, and the charge efficiency is also influenced, so that the dust collection efficiency of the electric field in the prior art is reduced, and the energy consumption is increased. When the gas inlet electric field device collects dust in gas, the gas and the dust enter an electric field along the direction of ion flow, the dust is fully charged, and the consumption of the electric field is low; the dust collecting efficiency of the monopole electric field can reach 99.99%. When gas and dust enter the electric field in the direction of the counter ion flow, the dust is insufficiently charged, the power consumption of the electric field is increased, and the dust collection efficiency is 40-75%. The ion flow formed by the air inlet electric field device in one embodiment of the invention is beneficial to unpowered fan fluid conveying, air inlet oxygenation, heat exchange and the like.

(2) When the air inlet electric field device detects that the electric field current is increased to a given value, the dust cleaning is completed by utilizing the electric field back corona discharge phenomenon.
(3) When the air inlet electric field device detects that the electric field current is increased to a given value, the electric field back corona discharge phenomenon is utilized, the electric field voltage is increased, the injection current is limited, and dust cleaning is completed.
(4) When the air inlet electric field device detects that the electric field current is increased to a given value, the electric field back corona discharge phenomenon is utilized, the electric field voltage is increased, the injection current is limited, and the rapid discharge generated at the position of the anode carbon deposition generates plasma, the plasma deeply oxidizes the organic components of the dust, the macromolecular bonds are broken, and micromolecular carbon dioxide and water are formed, so that the dust cleaning is completed.

Specifically, when the gas containing particulate matters enters the centrifugal separation mechanism 1012 from the inlet 1011 of the air inlet dedusting system at a speed of 12-30m/s, the gas changes from linear motion to circular motion.

Example 17
The electric field device in this embodiment can be applied to an air intake system, and includes a dust removal electric field cathode 5081 and a dust removal electric field anode 5082 electrically connected to the cathode and the anode of the dc power supply, respectively, and an auxiliary electrode 5083 electrically connected to the anode of the dc power supply. In this embodiment, the dedusting electric field cathode 5081 has a negative potential, and the dedusting electric field anode 5082 and the auxiliary electrode 5083 each have a positive potential.
Meanwhile, as shown in fig. 13, the auxiliary electrode 5083 is fixedly connected to the dust removing field anode 5082 in this embodiment. After the dedusting electric field anode 5082 is electrically connected to the anode of the dc power supply, the auxiliary electrode 5083 is also electrically connected to the anode of the dc power supply, and the auxiliary electrode 5083 and the dedusting electric field anode 5082 have the same positive potential.
As shown in fig. 13, the auxiliary electrode 5083 may extend in the front-rear direction in this embodiment, i.e., the length direction of the auxiliary electrode 5083 may be the same as the length direction of the dust removing field anode 5082.
As shown in fig. 13, in this embodiment, the dust-removing electric field anode 5082 is tubular, the dust-removing electric field cathode 5081 is rod-shaped, and the dust-removing electric field cathode 5081 is inserted into the dust-removing electric field anode 5082. In the present embodiment, the auxiliary electrode 5083 is also tubular, and the auxiliary electrode 5083 and the dust removing electric field anode 5082 form an anode tube 5084. The front end of the anode tube 5084 is flush with the dedusting electric field cathode 5081, the rear end of the anode tube 5084 is extended rearward beyond the rear end of the dedusting electric field cathode 5081, and the portion of the anode tube 5084 extended rearward beyond the dedusting electric field cathode 5081 is the auxiliary electrode 5083. That is, in this embodiment, the dust removal electric field anode 5082 and the dust removal electric field cathode 5081 have the same length, and the dust removal electric field anode 5082 and the dust removal electric field cathode 5081 are opposite to each other in position in the front-rear direction; the auxiliary electrode 5083 is located behind the dedusting electric field anode 5082 and the dedusting electric field cathode 5081. Thus, an auxiliary electric field is formed between the auxiliary electrode 5083 and the dedusting electric field cathode 5081, and the auxiliary electric field applies a backward force to the negatively charged oxygen ion stream between the dedusting electric field anode 5082 and the dedusting electric field cathode 5081, so that the negatively charged oxygen ion stream between the dedusting electric field anode 5082 and the dedusting electric field cathode 5081 has a backward moving speed. When the gas containing the substances to be treated flows into the anode tube 5084 from front to back, the oxygen ions with negative charges are combined with the substances to be treated in the process of moving towards the anode 5082 of the dust removal electric field and moving backwards, and because the oxygen ions have backward moving speed, the oxygen ions are combined with the substances to be treated, and strong collision cannot be generated between the oxygen ions and the substances to be treated, so that the larger energy consumption caused by the strong collision is avoided, the oxygen ions are easily combined with the substances to be treated, the charging efficiency of the substances to be treated in the gas is higher, further, under the action of the anode 5082 of the dust removal electric field and the anode tube 5084, more substances to be treated can be collected, and the higher dust removal efficiency of the electric field device is ensured.
In addition, as shown in fig. 13, in the present embodiment, an angle α is formed between the rear end of the anode 5084 and the rear end of the dust-removing electric field cathode 5081, and 0 ° < α ≦ 125 °, or 45 ° ≦ α ≦ 125 °, or 60 ° ≦ α ≦ 100 °, or α ≦ 90 °.
In this embodiment, the dust removing electric field anode 5082, the auxiliary electrode 5083, and the dust removing electric field cathode 5081 form a plurality of dust removing units, so as to effectively improve the dust removing efficiency of the electric field apparatus by using the plurality of dust removing units.
In this embodiment, the substance to be treated may be dust in the form of particles or other impurities to be treated.
In this embodiment, the gas may be a gas to be introduced into the engine or a gas discharged from the engine.
The dc power supply in this embodiment 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. In the absence of the auxiliary electrode 5083, the ion flow in the electric field between the dedusting electric field cathode 5081 and the dedusting electric field anode 5082 is perpendicular to the electrode direction, and turns back and flows between the two electrodes, and the ions are consumed by turning back and forth between the electrodes. Therefore, in this embodiment, the auxiliary electrode 5083 is used to shift the relative positions of the electrodes, so that the relative imbalance between the anode 5082 of the dedusting electric field and the cathode 5081 of the dedusting electric field is formed, which causes the ion current in the electric field to deflect. In the electric field device, an auxiliary electrode 5083 forms an electric field that can provide an ion flow with directionality. The electric field device in the present embodiment is also referred to as an electric field device having an acceleration direction. The collecting rate of the particles entering the electric field along the ion flow direction is improved by nearly one time compared with the collecting rate of the particles entering the electric field along the reverse ion flow direction, so that the dust accumulation efficiency of the electric field is improved, and the 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 low is that the direction of dust entering the electric field is opposite to or perpendicular to the direction of ion flow in the electric field, so that the dust and the ion flow collide violently with each other and generate large energy consumption, and the charge efficiency is also influenced, so that the dust collection efficiency of the electric field in the prior art is 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 the electric field along the ion flow direction, so that the dust is fully charged, and the electric field consumption is low; the dust collecting efficiency of the monopole electric field can reach 99.99%. When gas and dust enter the electric field along the direction of the counter-ion flow, the dust is insufficiently charged, the power 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 unpowered fan fluid conveying, oxygen increasing, heat exchange and the like.
Example 18

In this embodiment, the auxiliary electrode 5083 and the dedusting electric field cathode 5081 both have a negative potential and the dedusting electric field anode 5082 has a positive potential.
In this embodiment, the auxiliary electrode 5083 may be fixedly connected to the dedusting electric field cathode 5081. Thus, after the dust removal field cathode 5081 is electrically connected to the cathode of the dc power supply, the auxiliary electrode 5083 is also electrically connected to the cathode of the dc power supply. Meanwhile, the auxiliary electrode 5083 extends in the front-rear direction in the present embodiment.
In this embodiment, the dust removing electric field anode 5082 is tubular, the dust removing electric field cathode 5081 is rod-shaped, and the dust removing electric field cathode 5081 is inserted into the dust removing electric field anode 5082. In this embodiment, the auxiliary electrode 5083 is also in the form of a rod, and the auxiliary electrode 5083 and the dust-removing field cathode 5081 constitute a cathode rod. The front end of the cathode rod is projected forward beyond the front end of the dust-removing field anode 5082, and the portion of the cathode rod projected forward beyond the dust-removing field anode 5082 is the auxiliary electrode 5083. That is, in this embodiment, the dust removal electric field anode 5082 and the dust removal electric field cathode 5081 have the same length, and the dust removal electric field anode 5082 and the dust removal electric field cathode 5081 are opposite to each other in position in the front-rear direction; the auxiliary electrode 5083 is located in front of the dedusting electric field anode 5082 and dedusting electric field cathode 5081. Thus, an auxiliary electric field is formed between the auxiliary electrode 5083 and the dedusting electric field anode 5082, and the auxiliary electric field applies a backward force to the negatively charged oxygen ion stream between the dedusting electric field anode 5082 and the dedusting electric field cathode 5081, so that the negatively charged oxygen ion stream between the dedusting electric field anode 5082 and the dedusting electric field cathode 5081 has a backward moving speed. When the gas containing the substances to be treated flows into the tubular dedusting electric field anode 5082 from front to back, the negatively charged oxygen ions are combined with the substances to be treated in the process of moving towards the dedusting electric field anode 5082 and backwards, and because the oxygen ions have backward moving speed, the oxygen ions are combined with the substances to be treated, and strong collision cannot be generated between the oxygen ions and the substances to be treated, so that the larger energy consumption caused by strong collision is avoided, the oxygen ions are easily combined with the substances to be treated, the charge efficiency of the substances to be treated in the gas is higher, and further, under the action of the dedusting electric field anode 5082, more substances to be treated can be collected, and the higher dedusting efficiency of the electric field device is ensured.
In this embodiment, the dust removing electric field anode 5082, the auxiliary electrode 5083, and the dust removing electric field cathode 5081 form a plurality of dust removing units, so as to effectively improve the dust removing efficiency of the electric field apparatus by using the plurality of dust removing units.
In this embodiment, the substance to be treated may be dust in the form of particles or other impurities to be treated.

As shown in fig. 14, the electric field device of the present embodiment is applicable to an intake system, and the auxiliary electrode 5083 extends in the right-left direction. In this embodiment, the length direction of the auxiliary electrode 5083 is different from the length direction of the dust removing electric field anode 5082 and the dust removing electric field cathode 5081. And the auxiliary electrode 5083 may be specifically perpendicular to the dedusting electric field anode 5082.

Example 22 (air inlet leading electrode)
As shown in fig. 16, the present embodiment provides an intake electric field device, which includes an intake electric field device inlet 3085, an intake runner 3086, an electric field runner 3087, and an intake electric field device outlet 3088, which are sequentially communicated, an intake leading electrode 3083 is installed in the intake runner 3086, a ratio of a cross-sectional area of the intake leading electrode 3083 to a cross-sectional area of the intake runner 3086 is 99% to 10%, the intake electric field device further includes an intake dedusting electric field cathode 3081 and an intake dedusting electric field anode 3082, and the electric field runner 3087 is located between the intake dedusting electric field cathode 3081 and the intake dedusting electric field anode 3082. The working principle of the air inlet electric field device is as follows: gas containing pollutants enters the air inlet runner 3086 through the air inlet electric field device inlet 3085, the air inlet prepositive electrode 3083 arranged in the air inlet runner 3086 conducts electrons to partial pollutants, partial pollutants are charged, after the pollutants enter the electric field runner 3087 through the air inlet runner 3086, the air inlet dedusting electric field anode 3082 applies attraction to the charged pollutants, the charged pollutants move towards the air inlet dedusting electric field anode 3082 until the partial pollutants are attached to the air inlet dedusting electric field anode 3082, meanwhile, an air inlet ionization dedusting electric field is formed between the air inlet dedusting electric field cathode 3081 and the air inlet dedusting electric field anode 3082 in the electric field runner 3087, the air inlet ionization dedusting electric field charges the other part of uncharged pollutants, so that the other part of pollutants are also attracted by the air inlet dedusting electric field anode 3082 after being charged and finally attached to the air inlet dedusting electric field anode 3082, therefore, the air inlet electric field device is utilized to enable the pollutants to be charged more efficiently and more sufficiently, so that the air inlet dedusting electric field anode 3082 can collect more pollutants, and the air inlet electric field device can ensure the pollutants to be collected more efficiently.
The cross-sectional area of the intake leading electrode 3083 refers to the sum of the areas of the intake leading electrode 3083 along the substantial portion of the cross-section. In addition, the ratio of the cross-sectional area of the inlet leading electrode 3083 to the cross-sectional area of the inlet runner 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 the present embodiment, the inlet leading electrode 3083 and the inlet dedusting electric field cathode 3081 are both electrically connected to the cathode of the dc power supply, and the inlet dedusting electric field anode 3082 is electrically connected to the anode of the dc power supply. In this embodiment, the inlet pre-electrode 3083 and the inlet de-dusting electric field cathode 3081 both have negative potentials, and the inlet de-dusting electric field anode 3082 has a positive potential.
As shown in fig. 16, the inlet leading electrode 3083 may be a mesh in this embodiment. Thus, when gas flows through the gas inlet channel 3086, the gas and pollutants can conveniently flow through the gas inlet preposed electrode 3083 by utilizing the characteristic that the gas inlet preposed electrode 3083 is in a net structure, and the pollutants in the gas can be more fully contacted with the gas inlet preposed electrode 3083, so that the gas inlet preposed electrode 3083 can conduct electrons to more pollutants, and the charging efficiency of the pollutants is higher.
As shown in fig. 16, in the present embodiment, the intake air dust removing electric field anode 3082 is tubular, the intake air dust removing electric field cathode 3081 is rod-shaped, and the intake air dust removing electric field cathode 3081 is inserted into the intake air dust removing electric field anode 3082. In this embodiment, the anode 3082 of the air inlet dedusting electric field and the cathode 3081 of the air inlet dedusting electric field are asymmetric. When the gas flows into the ionization electric field formed between the inlet dedusting electric field cathode 3081 and the inlet dedusting electric field anode 3082, the pollutants are charged, and under the action of the attraction force exerted by the inlet dedusting electric field anode 3082, the charged pollutants are collected on the inner wall of the inlet dedusting electric field anode 3082.
In addition, as shown in fig. 16, in the present embodiment, both the intake air dust removal electric field anode 3082 and the intake air dust removal electric field cathode 3081 extend in the front-rear direction, and the front end of the intake air dust removal electric field anode 3082 is located in front of the front end of the intake air dust removal electric field cathode 3081 in the front-rear direction. As shown in fig. 16, the rear end of the intake dust removing field anode 3082 is located behind the rear end of the intake dust removing field cathode 3081 in the front-rear direction. In this embodiment, the length of the anode 3082 of the air intake dust removal electric field is longer in the front-rear direction, so that the area of the adsorption surface on the inner wall of the anode 3082 of the air intake dust removal electric field is larger, the attraction force on the pollutants with negative potential is larger, and more pollutants can be collected.
As shown in fig. 16, in the present embodiment, the cathode 3081 of the air intake dust removal electric field and the anode 3082 of the air intake dust removal electric field form a plurality of ionization units, so that more pollutants can be collected by the ionization units, and the air intake electric field apparatus has a stronger pollutant collecting capability and a higher collecting efficiency.
In this embodiment, the contaminants include common dust with low conductivity, and metal dust, mist, aerosol with high conductivity. The gas inlet electric field device in the embodiment is used for collecting common dust with weak conductivity and pollutants with strong conductivity in gas as follows: when gas flows into the gas inlet channel 3086 through the gas inlet electric field device inlet 3085, pollutants such as metal dust, fog drops or aerosol with strong conductivity in the gas are directly negatively charged when contacting with the gas inlet preposed electrode 3083 or when the distance between the pollutants and the gas inlet preposed electrode 3083 reaches a certain range, then all the pollutants enter the electric field channel 3087 along with the gas flow, the gas inlet dust removing electric field anode 3082 exerts attraction force on the negatively charged metal dust, fog drops or aerosol and the like and collects the partial pollutants, meanwhile, the gas inlet dust removing electric field anode 3082 and the gas inlet dust removing electric field cathode 3081 form an ionization electric field, the ionization electric field obtains oxygen ions through oxygen in ionized gas, and after the negatively charged oxygen ions are combined with common dust, the common dust is negatively charged, the gas inlet dust removing electric field anode 3082 exerts attraction force on the partially negatively charged dust, and collect this part pollutant to collect the pollutant that electric conductivity is stronger and electric conductivity is weaker in the gas, and make the kind of the material that this electric field device of admitting air can collect more extensive, and the collection ability is stronger.
The intake air dust removal 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. A direct current high voltage is introduced between the air inlet prepositive electrode 3083 and the air inlet dedusting electric field anode 3082 to form a conductive loop; and a direct-current high voltage is introduced between the cathode 3081 of the air inlet dust removal electric field and the anode 3082 of the air inlet dust removal electric field to form an ionization discharge corona electric field. The inlet leading electrode 3083 in this embodiment is a densely distributed conductor. When dust which is easy to be charged passes through the air inlet preposed electrode 3083, the air inlet preposed electrode 3083 directly gives electrons to the dust, the dust is charged, and then the dust is adsorbed by the air inlet dedusting electric field anode 3082 with different poles; meanwhile, uncharged dust passes through an ionization region formed by the cathode 3081 of the air inlet dust removal electric field and the anode 3082 of the air inlet dust removal electric field, ionized oxygen formed in the ionization region charges electrons to the dust, and the dust is continuously charged and adsorbed by the anode 3082 of the air inlet dust removal electric field with different poles.
The air inlet electric field device in the embodiment can form two or more electrifying modes. For example, when the oxygen in the gas is sufficient, the ionization discharge corona electric field formed between the cathode 3081 and the anode 3082 of the air inlet dust removal electric field can be used to ionize the oxygen to charge the pollutants, and then the anode 3082 of the air inlet dust removal electric field is used to collect the pollutants; when the oxygen content in the gas is too low or in an oxygen-free state or the pollutants are conductive dust fog and the like, the pollutants are directly electrified by the gas inlet preposed electrode 3083, and are adsorbed by the gas inlet dedusting electric field anode 3082 after being fully electrified. In the embodiment, the electric fields of the two charging modes are adopted, so that high-resistance dust which is easy to charge and low-resistance metal dust, aerosol, liquid mist and the like which are easy to electrify can be collected at the same time. The two electrifying modes are used simultaneously, and the application range of the electric field is expanded.
