Description

Top electromagnetic hammer vibration electric dust collector with conductive filter tank

Technical Field

The invention relates to the technical field of electric dust removal, in particular to a top electromagnetic hammer vibrating electric dust remover with a conductive filter tank.

Background

Due to the corona discharge, a large amount of anions and cations are generated in each electric field path of the top electromagnetic hammer rapping electric precipitator. Negative ions in each corona region transfer negative charges to dust and make the negative charges into negatively charged dust when the negative ions collide with the dust in the process of moving towards anode plates positioned at the left side and the right side of a corresponding electric field channel; the negatively charged dust then moves towards the outlet end of the electric field channel under the action of wind force and moves towards the anode plates positioned at the left or right side of the electric field channel under the action of electric field force, and most of the negatively charged dust is accumulated on the surfaces of the anode plates, and the rest of the negatively charged dust escapes along with the air flow from the outlet end of the electric field channel-naturally, the negatively charged dust escaping along with the air flow from the left and right sides of the outlet end of the electric field channel is significantly more than the negatively charged dust escaping along with the air flow from the middle part of the outlet end of the electric field channel.

When the cathode electromagnetic hammer vibrator (or the anode electromagnetic hammer vibrator) of the top electromagnetic hammer vibration electric dust collector is used for vibrating and cleaning dust on the cathode wire (or the anode plate), the vibration force is transmitted downwards from the top end of the cathode frame (or the anode plate row), so that the distribution rule of vibration acceleration generated on the cathode wire (or the anode plate) is big in top and small in bottom, and the vibration acceleration is consistent with the dust cleaning requirement of the cathode wire (or the anode plate). Therefore, people widely apply the top electromagnetic hammer to shake the electric dust collector in the industries of thermal power generation, steel, nonferrous metallurgy, chemical industry, building materials, machinery, electronics and the like.

In order to meet the increasing requirements of graceful ecological environment, people hopefully want to remarkably improve the dust removal efficiency of the top electromagnetic hammer vibrating electric dust remover and remarkably reduce the dust concentration of the outlet flue gas. Therefore, in the top electromagnetic hammer rapping electric precipitator, how to efficiently trap the charged dust which escapes from the left and right sides and the middle of the outlet end of each electric field channel along with the airflow in the corresponding electric field at least at the downstream of a plurality of electric field channels of the electric field is a technical problem which is needed to be solved by the person skilled in the art.

In the top electromagnetic hammer rapping electric dust remover provided by the invention, at least a plurality of conductive filter grooves which can form a row of conductive filter grooves are correspondingly arranged right behind a plurality of second anode plate rows of an electric field one by one, and a plurality of cylindrical cathode lines or tubular cathode lines which are smooth in side surface and connected with a plurality of second cathode lines positioned right in front of the conductive filter grooves are arranged between any two conductive filter grooves which are adjacent left and right.

At the same time, as the dust escaping from the middle of the outlet end of each electric field channel is discharged, the dust can continue to charge or start to charge after entering the channel between the two corresponding conductive filter cells, and the charged dust moves leftwards or rightwards under the action of the electric field force while advancing towards the outlet end of the channel under the action of the wind force, more precisely, the negatively charged dust in the left side and the right side of the channel tends to the conductive filter cell positioned at the left side of the central line of the channel and the conductive filter cell positioned at the right side of the central line of the channel respectively under the combined action of the wind force and the electric field force, and a part of the negatively charged dust is accumulated on the side part of a metal wire mesh or a porous foam metal plate of the conductive filter cell, and the positively charged dust in the channel tends to a plurality of cylindrical cathode wires or tubular cathode wires positioned in the channel and a part of the positively charged dust is accumulated on the cathode wires.

When the two first anode plate rows and the two second anode plate rows which are positioned at the upstream of the two corresponding conductive filter tanks are rapped, secondary dust is generated in the corresponding two and three electric field channels (charging: can be carried out), wherein a part of the secondary dust can also enter the two conductive filter tanks along with air flow, and is effectively trapped by the two conductive filter tanks under the dual effects of electrostatic adsorption and interception filtration, namely, a plurality of secondary dust is accumulated on the metal wire mesh or the porous foam metal plate of the two conductive filter tanks, a part of the secondary dust can enter the channel between the two conductive filter tanks along with air flow, and is continuously charged or starts to be charged, and meanwhile, under the combined effect of wind power and electric field force, the negatively charged secondary dust and the positively charged secondary dust respectively tend to the two conductive filter tanks and the corresponding cylindrical cathode wires or the tubular cathode wires, and a plurality of the negatively charged secondary dust is accumulated on the metal wire mesh or the porous foam metal plate of the two conductive filter tanks, and a plurality of the negatively charged secondary dust is accumulated on the cylindrical cathode wires or the tubular cathode wires.

Because the conductive filter cell and the cylindrical cathode line or the tubular cathode line in the invention are at least effectively trapped downstream of a plurality of electric field channels of one electric field, and some secondary dust generated when the first anode plate row and the second anode plate row of the corresponding electric field are rapped, the dust removing efficiency of the top electromagnetic hammer rapping electric dust remover provided with the conductive filter cell can be further improved, and the dust concentration of the outlet flue gas can be further reduced.

Further, the plurality of cylindrical cathode wires or the tubular cathode wires are fixedly connected with the second cathode frame positioned right in front of the cylindrical cathode wires or fixedly installed on the same second cathode frame together with the plurality of second cathode wires positioned right in front of the cylindrical cathode wires or the tubular cathode wires through the plurality of rigid connectors, so that the cylindrical cathode wires and the plurality of second cathode wires connected with the cylindrical cathode wires can share one set of high-voltage power supply device together, and a special suspension device, an anti-swing device and a vibration ash removing device are not required to be arranged, thereby reducing the manufacturing cost of the electric dust remover; moreover, they can be firmly installed on the cathode system of the electric dust collector, so that the probability of electric field short circuit caused by breakage (or broken line) of the second cathode lines is remarkably reduced, and when the second cathode lines connected with the second cathode lines are rapped for ash removal, the second cathode lines can obtain proper large rapping acceleration and good ash removal effect.

Detailed Description

In order to make the object and technical scheme of the present invention more clear, the following description of the present invention will be further described with reference to the accompanying drawings and examples.

First embodiment

As shown in fig. 1 to 7, the top electromagnetic hammer rapping electric precipitator provided with the conductive filter cells according to the present invention comprises an air inlet box 100, a casing 200, a first electric field with a same pole distance B of 400mm and a number of electric field channels of nine, a second electric field with a same pole distance B of 450mm and a number of electric field channels of eight, an air outlet box 700, sixteen cathode electromagnetic hammer rappers, fourteen anode electromagnetic hammer rappers and six filter cell electromagnetic hammer rappers (all not shown in the drawing) arranged on the top of the electric precipitator, wherein the six filter cell electromagnetic hammer rappers (all are not shown in the drawing) are used for removing dust accumulated on a row of conductive filter cells (I) 510, a row of conductive filter cells (II) 520 and another row of conductive filter cells located behind the electric precipitator, namely a row of conductive filter cells (III) 530.

The first electric field includes a first electric field front region and a first electric field rear region, and the first high-frequency high-voltage power supply device (I) 810 and the second high-frequency high-voltage power supply device (I) 820 perform partition power supply to prevent the operation conditions of the first electric field front region and the first electric field rear region from being affected mutually, so that the two electric field partitions work in the optimal state respectively, and the operation voltage and the dust removal efficiency of the first electric field rear region are improved obviously. The second electric field includes a second electric field front region and a second electric field rear region, and the first high-frequency high-voltage power supply device (II) 830 and the second high-frequency high-voltage power supply device (II) 840 perform partition power supply, so as to prevent the operation conditions of the second electric field front region and the second electric field rear region from being affected mutually, so that the two electric field partitions respectively work in an optimal state, and the operation voltage and the dust removal efficiency of the second electric field rear region are obviously improved.

The first electric field front region comprises four anode electromagnetic hammer rappers, four cathode electromagnetic hammer rappers, ten first anode plate rows (I) 311 and nine first cathode frames (I) 411 which are arranged in parallel at intervals, and is provided with a first high-frequency high-voltage power supply device (I) 810; the first electric field rear region comprises four anode electromagnetic hammer rappers, four cathode electromagnetic hammer rappers, ten second anode plate rows (I) 321 and nine second cathode frames (I) 421 which are arranged in parallel at intervals, and a second high-frequency high-voltage power supply device (I) 820 is arranged, wherein the structure of the second anode plate row (I) 321 is identical to that of the first anode plate row (I) 311, and four second anode plates (I) 3211 are BE-type anode plates with the height equal to h (note: h is between 7 meters and 15 meters).

Each first cathode frame (I) 411 comprises two first cathode frame main masts (I) vertically arranged and a plurality of first cathode frame transverse pipes (I) fixedly connected with the first cathode frame main masts, and eight first cathode wires (I) (note: CS10A type needling wires), wherein each first cathode frame transverse pipe (I) is fixedly connected with eight first cathode wires (I), and each second cathode frame (I) 421 comprises two second cathode frame main masts (I) 4213 vertically arranged and a plurality of second cathode frame transverse pipes (I) 4212 fixedly connected with the second cathode frame main masts, and eight second cathode wires (I) 4211 (note: CS10A type needling wires), wherein each second cathode frame transverse pipe (I) 4212 is fixedly connected with eight second cathode wires (I) 4211. In practice, the structure of the first cathode frame (I) 411 is identical to the structure of the second cathode frame (I) 421. It should be noted that the nine first cathode frames (I) 411 of the front region of the first electric field are not allowed to be electrically connected to the nine second cathode frames (I) 421 of the rear region of the first electric field, so that the first electric field performs the partitioned power supply.

Ten conductive filter cells 511 which can form a row of conductive filter cells (I) 510 are arranged right behind ten second anode plate rows (I) 321 in a one-to-one correspondence manner, two cylindrical cathode lines (I) 6101 with smooth side surfaces and fixedly connected with one second cathode frame (I) 421 positioned right in front of the conductive filter cells are arranged between any two adjacent conductive filter cells 511, wherein the diameter of the cylindrical cathode line (I) 6101 is 15mm or 18mm, the material of the cylindrical cathode line (I) 6101 is Q235-a, and the rigid connecting member (I) 6102 is cylindrical or tubular. Each conductive filter cell 511 in the row of conductive filter cells (I) 510 has air permeability; the air inlet of each conductive filter slot 511 faces the air outlet end of the second anode plate (I) 3211 located directly in front of the air inlet.

Specifically, the front ends of the rigid connecting pieces (I) 6102 (note: Q235-A) welded with the two cylindrical cathode lines (I) 6101 are butt welded with the rear ends of the plurality of second cathode frame cross tubes (I) 4212 of the second cathode frame (I) 421 directly in front of the same in a one-to-one correspondence manner, so that even though the two cylindrical cathode lines (I) 6101 are electrically connected with the eight second cathode lines (I) 4211 directly in front of the same, the two cylindrical cathode lines (I) 6101 can share a second high-frequency high-voltage power supply device (I) 820 with the eight second cathode lines (I) 4211 directly in front of the same, the two cylindrical cathode lines (I) 6101 are rigidly connected with the plurality of second cathode frame cross tubes (I) 4212 and the eight second cathode lines (I) 4211) directly in front of the same, when the first cathode line (I) is in any area, the vibration of the first cathode frame is in a vibration beating machine, the vibration of the first cathode line (I) is transferred to the plurality of second cathode frames (I) 4211) directly to the main cathode lines (I) 4213 through the second cathode lines (I) 4211), and the vibration force is transferred to the main cathode lines (I) 4213 directly to the main cathode lines (I) 4211) through the second cathode frames (I) which are directly transferred to the main cathode lines (I) 4213), and generates proper large vibration acceleration on the dust collector so as to obtain good dust removing effect. Obviously, the cylindrical cathode line (I) 6101 is installed in this way, and a suspension device, an anti-swing device and a vibration ash removing device special for the cylindrical cathode line (I) 6101 are not required to be arranged, and the cylindrical cathode line (I) 6101 is difficult to break (or called broken line). It should be noted that the lifting height of the rapping hammer of the cathode electromagnetic hammer rapper in the rear region of the first electric field should be greater than the lifting height of the rapping hammer of the cathode electromagnetic hammer rapper in the front region of the first electric field by more than 30mm, so as to avoid the problem of dust accumulation on the second cathode line (I) 4211 and/or the cylindrical cathode line (I) 6101 due to the small rapping acceleration on the second cathode line (I) 4211 and/or the cylindrical cathode line (I) 6101.

Since the side surface of the cylindrical cathode line (I) 6101 is smooth and the CS10A type needling wire has a needle tip discharge structure, and the diameter (note: 15mm or 18 mm) of the cylindrical cathode line (I) 6101 is significantly larger than the main body diameter (note: 8 mm) of the CS10A type needling wire, the discharge property of the CS10A type needling wire is significantly higher than that of the cylindrical cathode line (I) 6101. In other words, the first and second cathode lines (I) 4211 are both significantly more discharge-able than the cylindrical cathode line (I) 6101. Of course, the cylindrical cathode line (I) 6101 can be changed into a tubular cathode line (Q235-A) with the outer diameter equal to 18mm, the wall thickness equal to 3.0mm and smooth side surfaces, so as to save the steel consumption.

In the row of conductive filter cells (I) 510, a third conductive filter cell 511 (note: serial number is numbered from left to right) and an eighth conductive filter cell 511 are respectively provided with one electromagnetic hammer vibrator of the filter cell directly above each other, so as to remove dust accumulated on five conductive filter cells 511 near the corresponding electromagnetic hammer vibrator of the filter cell in good time respectively, and avoid the problem of increasing the length of the shell 200 due to the arrangement of the vibration ash removing device of the filter cell, thereby saving the occupied area of the electric precipitator. The rapping acceleration distribution rules on each conductive filter cell 511 in the row of conductive filter cells (I) 510 are large at the upper part and small at the lower part, so that the rapping acceleration at the upper part is required to be larger than that at the lower part in accordance with the ash cleaning requirements of the conductive filter cells 511, because the dust accumulated on the upper parts of the conductive filter cells 511 is thinner and more viscous. It should be noted that the rapping ash removal period of the conductive filter slots (I) 510 of a row should be significantly shorter than that of the ten second anode plate rows (I) 321, so as to avoid serious secondary dust emission caused by too much dust accumulated on the conductive filter slots 511 thereof.

The second electric field front region comprises three anode electromagnetic hammer rappers, four cathode electromagnetic hammer rappers, nine first anode plate rows (II) 331 and eight first cathode frames (II) 431 which are arranged in parallel at intervals, and is provided with a first high-frequency high-voltage power supply device (II) 830; the second electric field rear region comprises three anode electromagnetic hammer rappers, four cathode electromagnetic hammer rappers, nine second anode plate rows (II) 341 and eight second cathode frames (II) 441 which are arranged in parallel at intervals, and a second high-frequency high-voltage power supply device (II) 840 is arranged, wherein the structure of the second anode plate row (II) 341 is identical to that of the first anode plate row (II) 331, and four second anode plates (II) 3411 are BE type anode plates with the height equal to h.

Each first cathode frame (II) 431 includes two first cathode frame main masts (II) vertically disposed and a plurality of first cathode frame transverse tubes (II) fixedly connected thereto, and eight first cathode wires (II) (note: CS10A type needling wire), wherein each first cathode frame transverse tube (II) is fixedly connected to eight first cathode wires (II), and each second cathode frame (II) 441 includes two second cathode frame main masts (II) 4413 vertically disposed and a plurality of first cathode frame transverse tubes (II) 4412 fixedly connected thereto, and eight second cathode wires (II) 4411 (note: CS10A type needling wire), wherein each second cathode frame transverse tube (II) 4412 is fixedly connected to eight second cathode wires (II) 4411. In practice, the structure of the first cathode frame (II) 431 is identical to the structure of the second cathode frame (II) 441. It should be noted that the eight first cathode frames (II) 431 of the front region of the second electric field are not allowed to be electrically connected to the eight second cathode frames (II) 441 of the rear region of the second electric field, so that the second electric field performs the partitioned power supply.

Nine conductive filter cells 511 which can form a row of conductive filter cells (II) 520 are disposed right behind the nine second anode plate rows (II) 341 in a one-to-one correspondence manner, and two cylindrical cathode lines (II) 6201 with smooth sides and fixedly connected with the second cathode frame (II) 441 located right in front of the two conductive filter cells 511 through a plurality of rigid connection pieces (II) 6202 are disposed between any two adjacent conductive filter cells 511, wherein the cylindrical cathode lines (II) 6201 are made of Q235-a and have a diameter equal to or slightly larger than the diameter of the cylindrical cathode lines (I) 6101, such as 15mm or 18mm, or 20mm, so that the discharge performance of the cylindrical cathode lines (I) 6101 is not more than that of the rigid connection pieces (II) 6202. The air inlet of each conductive filter cell 511 in a row of conductive filter cells (II) 520 faces the air outlet end of the second anode plate (II) 3411 located directly in front of it.

Specifically, the front ends of a plurality of rigid connectors (II) 6202 (note: Q235-A) welded with the two cylindrical cathode wires (II) 6201 are butt welded with the rear ends of a plurality of second cathode frame transverse tubes (II) 4412 of the second cathode frame (II) 441 positioned right in front of the same in a one-to-one correspondence manner, so that even though the two cylindrical cathode wires (II) 6201 are electrically connected with the eight second cathode wires (II) 4411 positioned right in front of the same, the cylindrical cathode wires (II) 6201 can be shared with the eight second cathode wires (II) 4411 positioned right in front of the same, the two cylindrical cathode wires (II) 6201 are also rigidly connected with the rear ends of a plurality of second cathode frame transverse tubes (II) 4412 positioned right in front of the same, when the vibrating and beating parts of any cathode in the rear area of the second electric field are in a vibrating and beating parts of the second cathode frames (4411) are directly transferred to the plurality of the main cathode frames (4413) through the second frames (4411) which are directly transferred to the main cathode frames (4413) of the same, and the main frames (4413) are further transferred to the main frames (4413) by the second cathode frames) which are directly connected with the second cathode frames (4411) to the main frames (II) which are positioned right in front of the same, and generates proper large vibration acceleration on the dust collector so as to obtain good dust removing effect. Obviously, the cylindrical cathode wire (II) 6201 is installed in this way, a suspension device, an anti-swing device and a vibration ash removing device special for the cylindrical cathode wire (II) 6201 are not required to be arranged, and the cylindrical cathode wire (II) 6201 is difficult to break (or called broken wire). It should be noted that the lifting height of the rapping hammer of the cathode electromagnetic hammer rapper in the rear region of the second electric field should be greater than the lifting height of the rapping hammer of the cathode electromagnetic hammer rapper in the front region of the second electric field by more than 30mm, so as to avoid the problem of dust accumulation on the second cathode line (II) 4411 and/or the cylindrical cathode line (II) 6201 due to the small rapping acceleration on the second cathode line (II) 4411 and/or the cylindrical cathode line (II) 6201.

Since the side surface of the cylindrical cathode wire (II) 6201 is smooth and the CS 10A-type needled wire has a needlepoint-shaped discharge structure, and the diameter of the cylindrical cathode wire (II) 6201 is significantly larger than the main body diameter (8 mm) of the CS 10A-type needled wire, the discharge property of the CS 10A-type needled wire is significantly stronger than that of the cylindrical cathode wire (II) 6201. In other words, the first and second cathode lines (II) and (II) 4411 are both significantly more dischargeable than the cylindrical cathode line (II) 6201. Of course, the cylindrical cathode wire (II) 6201 can be changed into a tubular cathode wire (Q235-A) with the outer diameter equal to 18mm, the wall thickness equal to 3.0mm and smooth side surface, so as to save the steel consumption.

In the row of conductive filter cells (II) 520, a third conductive filter cell 511 (note: serial number is numbered from left to right) and a seventh conductive filter cell 511 are respectively provided with one electromagnetic hammer vibrator of the filter cell directly above each other, so as to remove dust accumulated on five conductive filter cells 511 near the corresponding electromagnetic hammer vibrator of the filter cell in good time respectively, and avoid the problem of increasing the length of the shell 200 due to the arrangement of the vibration ash removing device of the filter cell, thereby saving the occupied area of the electric precipitator. It should be noted that the rapping ash removal period of the conductive filter cell (II) 520 of one row should be significantly shorter than that of the second anode plate row (II) 341, so as to avoid serious secondary dust emission due to too much dust accumulated on the conductive filter cells 511 thereof.

Most of the negatively charged dust escaping along the surfaces of the two second anode plates (I) 3211 (or the second anode plates (II) 3411) correspondingly arranged on the left and right sides of the outlet end of each electric field channel of the first electric field (or the second electric field) can enter the two conductive filter tanks 511 arranged right behind the corresponding two second anode plate rows (I) 321 (or the second anode plate row (II) 341) along with the airflow, and is effectively trapped by the two conductive filter tanks 511 under the dual effects of electrostatic adsorption and interception filtration, and a lot of negatively charged dust is accumulated on the wire mesh 5111 thereof.

At the same time, as the air flows escape from the middle of the outlet end of each electric field channel of the first electric field (or the second electric field), after entering the channel between the two conductive filter cells 511, the dust can continue to be charged or start to be charged, and the charged dust moves leftwards or rightwards while advancing towards the outlet end of the channel under the action of wind force, namely, under the action of wind force and electric field force, the negatively charged dust in the left side and the right side of the channel tends to the conductive filter cell 511 positioned at the left side of the center line of the channel and the conductive filter cell 511 positioned at the right side of the center line of the channel respectively, and a part of the negatively charged dust is accumulated on the wire mesh 5111, while the positively charged dust in the channel tends to the two cylindrical cathode wires (I) 6101 (or the cylindrical cathode wires (II) 6201) positioned in the channel, and a part of the positively charged dust is accumulated on the cylindrical cathode wires.

When the two first anode plate rows (I) 311 and the two second anode plate rows (I) 321 (or the two first anode plate rows (II) 331 and the two second anode plate rows (II) 341) located right in front of the two conductive filter tanks 511 are rapped, secondary dust (can be charged) is generated in the corresponding two and three electric field channels, wherein a part of the secondary dust can also enter the two conductive filter tanks 511, and is effectively trapped by the two conductive filter tanks 511 under the dual effects of electrostatic adsorption and interception filtration, a plurality of secondary dust is accumulated on the wire mesh 5111 of the two conductive filter tanks 511, a part of the secondary dust can enter the channel between the two conductive filter tanks 511, and is continuously charged or starts to be charged, and simultaneously, under the combined effect of wind power and electric field force, the negatively charged secondary dust and the positively charged secondary dust respectively trend towards the two conductive filter tanks 511 and the corresponding two cylindrical cathode wires (I) 6101 or the cylindrical cathode wires (6201) and the cylindrical cathode wires (I) are accumulated on the cylindrical cathode wires (6201).

In summary, a row of conductive filter cells (I) 510 and eighteen cylindrical cathode lines (I) 6101, a row of conductive filter cells (II) 520 and sixteen cylindrical cathode lines (II) 6201, respectively, are efficiently trapped downstream of nine electric field channels of the first electric field and downstream of eight electric field channels of the second electric field, respectively, and the charged dust escaping from the left and right sides and the middle of the outlet end of each electric field channel of the corresponding electric field with the air current contains a portion of the secondary dust generated when the anode plate of the corresponding electric field is rapped, thereby significantly improving the dust removal efficiency of the electric precipitator and significantly reducing the dust concentration of the outlet flue gas.

In addition, the air inlets of the eight conductive filter cells 511 that may constitute the row of conductive filter cells (III) 530 are respectively directed toward the cylindrical cathode line (II) 6201 located right in front of the same, so as to efficiently capture the charged dust escaping from the middle of the outlet end of each electric field channel of the second electric field along with the air flow and the dust escaping from the meshes of the wire mesh 5111 of each conductive filter cell 511 in the row of conductive filter cells (II) 520, wherein the dust contains a part of the secondary dust generated when the anode plate and the cathode line of the second electric field and the row of conductive filter cells (II) 520 are rapped, thereby further improving the dust removal efficiency of the second electric field. It should be noted that the distance between each conductive filter cell 511 in the row of conductive filter cells (III) 530 and the rigid connection pieces (II) 6202 (or the cylindrical cathode line (II) 6201) located directly in front of it should be greater than the distance between any one cylindrical cathode line (II) 6201 and the two conductive filter cells 511 (note: belonging to the row of conductive filter cells (II) 520) located on the left and right sides thereof, so as not to cause a drop in the operating voltage in the rear region of the second electric field.

In the row of conductive filter cells (III) 530, a second conductive filter cell 511 (note: serial number is numbered from left to right) and a seventh conductive filter cell 511 are respectively provided with one electromagnetic hammer vibrator of the filter cell directly above each other, so as to remove dust accumulated on four conductive filter cells 511 near the corresponding electromagnetic hammer vibrator of the filter cell in good time respectively, and avoid the problem of increasing the length of the casing 200 due to the arrangement of the vibration ash removing device of the filter cell, thereby saving the occupied area of the electric precipitator.

Each first cathode frame (I) 411 'comprises a first cathode frame main mast (I) and a plurality of first cathode frame transverse pipes (I) fixedly connected with the first cathode frame main mast (I) which are vertically arranged, and eight first cathode wires (I) (note: CS10A type needle punched wires), wherein each first cathode frame transverse pipe (I) is fixedly connected with eight first cathode wires (I), each second cathode frame (I) 421' comprises a second cathode frame main mast (I) 4213 'and a plurality of second cathode frame transverse pipes (I) 4212' fixedly connected with the second cathode frame main mast, and eight second cathode wires (I) 4211 '(note: CS10A type needle punched wires) and two tubular cathode wires (I) 6101' with smooth sides, each second cathode frame transverse pipe (I) 4212 'is fixedly connected with eight second cathode wires (I) 4211' and two tubular cathode wires (I) 6101', and two tubular cathode wires (I) 6101' are arranged between two rows of conductive grooves (I) of conductive grooves 510). Naturally, the length of the second cathode frame cross tube (I) 4212' is significantly greater than the length of the first cathode frame cross tube (I).

Each conductive filter cell 511' in the row of conductive filter cells (I) 510' has air permeability, and its air inlet faces the air outlet end of the second anode plate (I) 3211' located directly in front of it. The air inlets of the nine conductive filter cells 511', which may constitute a row of conductive filter cells (II) 520', are all directed toward the one tubular cathode line (I) 6101' located right in front of them. It should be noted that the distance between each conductive filter cell 511 'in the row of conductive filter cells (II) 520' and the second cathode frame (I) 421 'located directly in front of it should be greater than the distance between any one of the second cathode frames (I) 421' and the two conductive filter cells 511 '(note: belonging to the row of conductive filter cells (I) 510') located on the left and right sides thereof so as not to cause a drop in the operating voltage of the first electric field.

The two tubular cathode wires (I) 6101' and the eight second cathode wires (I) 4211' located right in front of the two tubular cathode wires (I) 6101' are fixedly installed on the same second cathode frame (I) 421', so that even though the two tubular cathode wires (I) 6101' are electrically connected with the eight second cathode wires (I) 4211' located right in front of the two tubular cathode wires (I) 6101', the two tubular cathode wires (I) 6101' can share a high-frequency high-voltage power supply device (I) 810' together with the eight second cathode wires (I) 4211' located right in front of the two tubular cathode wires (I) 4211', the two tubular cathode wires (I) 6101' and the eight second cathode wires (I) 4211' located right in front of the two tubular cathode wires are rigidly connected with a plurality of second cathode frame transverse tubes (I) 4212', so that when any one cathode electromagnetic hammer close to the first electric field outlet section generates a part of the two tubular cathode wires (I) can be rapped, a part of the rapping force generated by the corresponding to the eight second cathode wires (I) 4211' can be transferred to the corresponding second cathode frame (I) 4211', and then the two cathode wires (I) can be rapped along with the two cathode frames (I) 4211 ') to the two cathode wires (I) located right in front of the second cathode frame (I) can be rapped. The tubular cathode line (I) 6101' is installed in this way, and a suspension device, an anti-swing device and a vibration ash removing device special for the tubular cathode line (I) 6101' are not required to be arranged, and the tubular cathode line (I) 6101' is difficult to break (or called broken line). It should be noted that the lifting height of the rapping hammer of the cathode electromagnetic hammer rapper near the first electric field outlet section should be greater than the lifting height of the rapping hammer of the cathode electromagnetic hammer rapper near the first electric field inlet section by more than 30mm, so as to avoid the problem of dust accumulation on the second cathode line (I) 4211 'and/or the tubular cathode line (I) 6101' due to the small rapping acceleration on the second cathode line (I) 4211 'and/or the tubular cathode line (I) 6101'.

The tubular cathode line (I) 6101' is made of an elliptical steel tube of Q235-A. The major and minor axes of the oval steel tube were 30mm and 18mm, respectively, and the nominal wall thickness was 2.0 mm-then the equivalent diameter of the tubular cathode line (I) 6101' was 17mm. The cross section of the tubular cathode line (I) 6101 'is elliptical, and the major axis of the ellipse is located on the symmetry center line of the corresponding second cathode frame (I) 421'; the side surface of the tubular cathode line (I) 6101' is smooth, the CS10A type needling line has a needlepoint discharge structure, and the long axis and the short axis of the tubular cathode line (I) 6101' are both obviously larger than the main body diameter (8 mm) of the CS10A type needling line, so that the discharge property of the CS10A type needling line is obviously higher than that of the tubular cathode line (I) 6101 '. In other words, the first and second cathode lines (I) and (I) 4211 'are both significantly more discharged than the discharge of the tubular cathode line (I) 6101'.

Of course, the tubular cathode line (I) 6101 'may be made of a seamless steel pipe (note: Q235-A) having an outer diameter of 18mm and a wall thickness of 2.0 mm-the cross section of this tubular cathode line (I) 6101' is circular, and its equivalent diameter is 14mm; the lateral area (note: the area for trapping positively charged dust) of this tubular cathode line (I) 6101' per meter length is equal to 56520mm ², and its mass is 0.789kg. Or the tubular cathode line (I) 6101' is changed to a cylindrical cathode line having a diameter equal to 18mm, then, the side area of such cylindrical cathode line per meter length (note: area for trapping positively charged dust) is also equal to 56520mm ², and the mass thereof is 1.997kg. By comparing the side areas and the mass of the two cathode wires in each meter length, compared with the cylindrical cathode wires with the diameter equal to 18mm, the tubular cathode wires with the outer diameter of 18mm and the wall thickness of 2.0mm can save the steel consumption.

In order to prevent the first cathode frame (I) 411' and the second cathode frame (I) 421' from rotating around the first cathode frame main mast (I) and the second cathode frame main mast (I) 4213', respectively, the uppermost one of the first cathode frame (I) 411' is connected to the uppermost one of the second cathode frame (I) 4212' of the second cathode frame (I) 421' located directly behind it by means of an anti-twist block, two bolts (not shown) and two washers (not shown) of a material Q235-a, and the lowermost one of the first cathode frame (I) 411' is also connected to the lowermost one of the second cathode frame (I) 4212' of the second cathode frame (I) 421' located directly behind it by means of one of the anti-twist block, two bolts and two washers, so that the first electric field cannot be applied.

In the row of conductive filter cells (I) 510', a third conductive filter cell 511' (note: serial number is compiled from left to right) and an eighth conductive filter cell 511' are respectively provided with one electromagnetic hammer vibrator of the filter cell directly above, so as to remove dust accumulated on five conductive filter cells 511' near the corresponding electromagnetic hammer vibrator of the filter cell in good time respectively, and avoid the problem of increasing the length of the shell 200' caused by setting a vibration ash removing device of the filter cell, thereby saving the occupied area of the electric dust collector. The rapping acceleration distribution pattern on each conductive filter cell 511 'in a row of conductive filter cells (I) 510' is large at the upper portion and small at the lower portion, so that it is consistent with the ash removal requirements of these conductive filter cells 511', since the dust deposited on the upper portions of these conductive filter cells 511' is relatively thin and relatively viscous, the rapping acceleration at the upper portions thereof is required to be larger than that at the lower portions thereof. It should be noted that the rapping ash removal period of the conductive filter tank row should be significantly shorter than that of the ten second anode plate rows (I) 321 'so as to avoid serious secondary dust emission problems due to too much dust accumulated on the conductive filter tank 511'.

In the row of conductive filter cells (II) 520', a third conductive filter cell 511' (note: serial number is compiled from left to right) and a seventh conductive filter cell 511' are respectively provided with one electromagnetic hammer vibrator of the filter cell directly above, so as to remove dust accumulated on five conductive filter cells 511' near the corresponding electromagnetic hammer vibrator of the filter cell in good time respectively, and avoid the problem of increasing the length of the shell 200' caused by setting a vibration ash removing device of the filter cell, thereby saving the occupied area of the electric dust collector.

Like the first embodiment of the row of conductive filter cells (II) 520, the row of conductive filter cells (III) 530 and the sixteen cylindrical cathode lines (II) 6201 located in front of them, the row of conductive filter cells (I) 510', the row of conductive filter cells (II) 520' and the eighteen tubular cathode lines (I) 6101' located in front of them can also efficiently trap the charged dust escaping from the left and right sides and the middle of the outlet end of each electric field channel of the first electric field with the air flow, wherein the charged dust contains a part of the secondary dust generated when the anode plate row of the first electric field is rapped, thereby significantly improving the dust removal efficiency of the first electric field and significantly reducing the dust concentration of the outlet flue gas of the electric dust collector; furthermore, the row of conductive filter cells (II) 520' can also efficiently trap dust escaping from the through holes of the porous foam metal plates 5111' of each conductive filter cell 511' in the row of conductive filter cells (I) 510', which contains a part of secondary dust generated when the anode plate row and cathode frame of the first electric field and the row of conductive filter cells (I) 510' are rapped, thereby further improving the dust removal efficiency of the first electric field.

The second electric field comprises six anode electromagnetic hammer rappers, four cathode electromagnetic hammer rappers, nine first anode plate rows (II) 331 'which are arranged in parallel in front of the anode electromagnetic hammer rappers and eight first cathode frames (II) 421', nine second anode plate rows (II) 341 'which are arranged in parallel in back of the anode electromagnetic hammer rappers and eight second cathode frames (II) 441' which are arranged right behind the nine second anode plate rows (II) 341 'in a one-to-one correspondence manner, nine conductive filter grooves 511' which can form a row of conductive filter grooves (III) 530', a row of conductive filter grooves (IV) 540' which are arranged behind the row of conductive filter grooves (III) 530', and a high-frequency high-voltage power supply device (II) 820'. The structure of the first anode plate row (II) 331 'is identical to the structure of the first anode plate row (II) 311'; the structure of the second anode plate row (II) 341 'is also identical to that of the first anode plate row (I) 311', and the four second anode plates (II) 3411 'are BE-type anode plates having a height h'.

Each first cathode frame (II) 431 'comprises a first cathode frame main mast (II) vertically arranged and a plurality of first cathode frame transverse pipes (II) fixedly connected with the first cathode frame main mast (II), and eight first cathode wires (II) (note: CS 10B-type needle punched wires), wherein each first cathode frame transverse pipe (II) is fixedly connected with eight first cathode wires (II), each second cathode frame (II) 441' comprises a second cathode frame main mast (II) 4413 'vertically arranged and a plurality of first cathode frame transverse pipes (II) 4412' fixedly connected with the second cathode frame main mast, and eight second cathode wires (II) 4411 '(note: CS 10B-type needle punched wires) and two tubular cathode wires (II) 6201' with smooth sides, wherein each second cathode frame transverse pipe (II) 4412 'is fixedly connected with eight second cathode wires (II) 4411' and two tubular cathode wires (II) 6201', and two tubular cathode wires (II) 6201' are arranged between two rows of filter grooves (6201) of the two electrode wires (6201) belong to a filter groove (III). Naturally, the length of the second cathode frame cross tube (II) 4412' is significantly greater than the length of the first cathode frame cross tube (II).

Naturally, in order to improve the uniformity of the distribution of the rapping acceleration of the cathode wires of each cathode frame of the two electric fields, it is also possible to mount two cathode frame reinforcing rods obliquely at both upper and lower portions thereof, and to weld each of the two ends of each cathode frame reinforcing rod to the upper or lower portion of the cathode frame main mast and the front (or rear) portion of the uppermost or lowermost one of the cathode frame transverse tubes, respectively. In addition, the anode plates in the first anode plate row (I) 311', the second anode plate row (I) 321', the first anode plate row (II) 331' and the second anode plate row (II) 341' can be changed to C480 type anode plates with the height equal to h ', and the specification code numbers of the anode electromagnetic hammer rappers are changed to DCh9-450, so as to improve the rapping acceleration of the C480 type anode plates.

The air inlet of each conductive filter cell 511' in a row of conductive filter cells (III) 530' faces the air outlet end of the second anode plate (II) 3411' located directly in front of it. The air inlets of the eight conductive filter cells 511', which may constitute a row of conductive filter cells (IV) 540', are all directed toward the one tubular cathode line (II) 6201' located right in front of it. It should be noted that the distance between each conductive filter cell 511 'in the row of conductive filter cells (IV) 540' and the second cathode frame (II) 441 'located directly in front of it should be greater than the distance between any one second cathode frame (II) 441' and the two conductive filter cells 511 '(note: belonging to the row of conductive filter cells (III) 530') located on the left and right sides thereof, so as not to cause a drop in the operating voltage of the second electric field.

The two tubular cathode wires (II) 6201 'and the eight second cathode wires (II) 4411' located right in front of the two tubular cathode wires (II) 6201 'are fixedly installed on the same second cathode frame (II) 441', so that even though the two tubular cathode wires (II) 6201 'are electrically connected with the eight second cathode wires (II) 4411' located right in front of the two tubular cathode wires (II) 6201', the two tubular cathode wires (II) 6201' can share a high-frequency high-voltage power supply device (II) 4411 'together with the eight second cathode wires (II) 4411' located right in front of the two tubular cathode wires, the two tubular cathode wires (II) 6201 'and the eight second cathode wires (II) 4411' located right in front of the two tubular cathode wires are rigidly connected with a plurality of corresponding second cathode frame transverse tubes (II) 4412', a part of the acceleration generated when the corresponding second cathode frame (II) and the corresponding second cathode frame transverse tube (II) and the eight cathode frame transverse tube (II) are in front of the two cathode frame transverse tubes 4411', and the two cathode frame transverse tubes (II) are in front of the two cathode frame transverse tubes (II) can be well transferred to the two cathode frames (II) and the two cathode frames (II) which are located right in front of the two cathode frame transverse frames (II) respectively. Obviously, the tubular cathode wire (II) 6201' is installed in this way, a suspension device, an anti-swing device and a vibration ash removing device special for the tubular cathode wire (II) 6201' are not needed, and the tubular cathode wire (II) 6201' is difficult to break (or called broken wire). It should be noted that the lifting height of the rapping hammer of the cathode electromagnetic hammer rapper near the second electric field outlet section should be greater than the lifting height of the rapping hammer of the cathode electromagnetic hammer rapper near the second electric field inlet section by more than 30mm, so as to avoid the problem of ash accumulation on the second cathode line (II) 4411 'and/or the tubular cathode line (I) 6201' due to the small rapping acceleration on the second cathode line (II) 4411 'and/or the tubular cathode line (II) 6201'.

The tubular cathode line (II) 6201' is made of an oval steel tube made of Q235-A. The major and minor axes of the oval steel tube were 34mm and 17mm, respectively, and the nominal wall thickness was 2.0 mm-then the equivalent diameter of the tubular cathode wire (II) 6201' was 16mm. The cross section of the tubular cathode line (II) 6201 'is elliptical, and the major axis of the ellipse is located on the symmetry center line of the corresponding second cathode frame (II) 441'; the side surface of the tubular cathode wire (II) 6201' is smooth, and the CS10B type needled wire has a needlepoint discharge structure, and the long axis and the short axis of the tubular cathode wire (II) 6201' are obviously larger than the main body diameter (8 mm) of the CS10B type needled wire, so that the discharge property of the CS10B type needled wire is obviously higher than that of the tubular cathode wire (II) 6201 '. In other words, the first and second cathode lines (II) and (II) 4411 'are both significantly more discharged than the tubular cathode line (II) 6201'. Of course, the tubular cathode wire (II) 6201 'may be made of a seamless steel pipe (Q235-A), which has an outer diameter of 22mm and a wall thickness of 2.0mm, and the tubular cathode wire (II) 6201' has a circular cross section and an equivalent diameter of 18mm.

In order to prevent the first cathode frame (II) 431' and the second cathode frame (II) 441' from rotating around the first cathode frame main mast (II) and the second cathode frame main mast (II) 4413', respectively, the uppermost one of the first cathode frame (II) 431' and the uppermost one of the second cathode frame (II) 441' are connected to the uppermost one of the second cathode frame (II) 441' located directly behind them through one of the anti-twist stoppers, two bolts (not shown in the drawings) and two washers (not shown in the drawings), and the lowermost one of the first cathode frame (II) 431' and the lowermost one of the second cathode frame (II) 4412' located directly behind them are also connected to the second cathode frame (II) 441' located directly behind them through one of the anti-twist stoppers, two bolts and two washers, respectively, whereby the second electric field cannot be applied.

It should be noted that the rapping ash removal period of the one row of conductive filter cells (III) 530' should be significantly shorter than the rapping ash removal period of the nine second anode plate rows (II) 341' to avoid serious secondary dust emission problems due to too much dust deposited on the conductive filter cells 511 '.

In the row of conductive filter cells (IV) 540', a second conductive filter cell 511' (note: serial number is numbered from left to right) and a seventh conductive filter cell 511' are respectively provided with one electromagnetic hammer vibrator of the filter cell directly above each other, so as to remove dust accumulated on four conductive filter cells 511' near the corresponding electromagnetic hammer vibrator of the filter cell in good time, and avoid the problem of increasing the length of the casing 200' due to the arrangement of the vibration ash removing device of the filter cell, thereby saving the occupied area of the electric precipitator.

Each conductive filter cell 511 'of the row of conductive filter cells (I) 510', the row of conductive filter cells (II) 520', the row of conductive filter cells (III) 530' and the row of conductive filter cells (IV) 540 'comprises a plurality of porous foam metal plates 5111' with edges fixedly provided with metal sealing edges, which are connected up and down. Of course, each porous metal foam plate 5111' may be formed by splicing a plurality of porous metal foam plates having relatively small side areas.

The porous foam metal plate 5111' is made of at least one of the following materials: iron, cobalt, nickel, copper, zinc; the thickness of the porous foam metal plate 5111' is between 10mm and 30mm, and the porosity thereof is between 50% and 90%. The upper and lower end edges of the porous foam metal plate 5111' are fixedly provided with a horizontally arranged high-level groove-shaped metal sealing edge 51122' and a symmetrical low-level groove-shaped metal sealing edge 51124', respectively, while the left and right front side edges thereof are fixedly provided with a left front side strip-shaped metal sealing edge 51125' and a symmetrical right front side strip-shaped metal sealing edge 51123', respectively. The upper ends of the left front side strip metal seal 51125 'and the upper ends of the right front side strip metal seal 51123' are respectively butt-welded with the left front end and the right front end of the high-level groove-shaped metal seal 51122', while the lower ends thereof are respectively butt-welded with the left front end and the right front end of the low-level groove-shaped metal seal 51124', and all butt-welded seams are flush in surface. In each conductive filter cell 511', each high-level channel metal seal 51122' is welded to a low-level channel metal seal 51124' adjacent to each other by butt welding and with the butt-welded surfaces flush. Of course, the cross section of each porous metal foam plate 5111 'of each conductive filter cell 511' may be changed to be V-shaped, and the outer shape of each high-level groove-shaped metal seal 51122 'and each low-level groove-shaped metal seal 51124' may be adaptively changed.

Although the above-described metal seal edge in the present invention causes the distance between the conductive filter tank 511 'and the tubular cathode line (I) 6101' or the tubular cathode line (II) 6201 'adjacent thereto to be slightly smaller, the above-described metal seal edge has little to no adverse effect on the breakdown voltage and the operation voltage of the two electric fields, because when one relatively independent small electric field is constituted by the conductive filter tank 511' and the tubular cathode line (I) 6101 '(or the tubular cathode line (II) 6201') adjacent thereto or the like, the distance therebetween is slightly smaller only to slightly lower the breakdown voltage of the relatively independent small electric field, but it is not lower than the breakdown voltage of the other relatively independent large electric field constituted by the first anode plate row (II) 321 'and the second cathode line (I) 4211' (or the second anode plate row (II) 341 'and the first cathode line (II) 4411') or the like, or it is only slightly lower than the latter.

Five additional points are described below:

First, although in the above two embodiments, the distances between each cylindrical cathode line or tubular cathode line of each electric field and the two conductive filter grooves located at the left and right sides thereof are slightly smaller than the distances between the first cathode line (or the second cathode line) of the corresponding electric field and the two anode plate rows located at the left and right sides thereof, the discharge performance of these cylindrical cathode lines or tubular cathode lines is significantly weaker than that of the first cathode line and the second cathode line of each electric field, so that the drop of the operating voltage of each electric field (or the electric field partition) is not caused. Naturally, these cylindrical cathode lines or tubular cathode lines do not reduce the efficiency of the two second anode plate rows located in front of them for capturing the charged dust in the gas stream nor do they reduce the efficiency of the two conductive filter cells located on the left and right sides thereof and the conductive filter cell located directly behind them (note: when provided) for capturing the charged dust in the gas stream.

Secondly, if the dust concentration of the inlet flue gas of the electric dust collector in the first embodiment (or the second embodiment) is higher, after the length of the shell is properly prolonged, a plurality of electric fields are additionally arranged at the upstream of the two electric fields, so that the dust concentration of the outlet flue gas of the electric dust collector meets strict environmental protection requirements; however, the added electric fields do not necessarily have to be provided with the conductive filter grooves and the cylindrical or tubular cathode lines.

Moreover, the shapes and dimensions of the various features in the drawings do not reflect actual sizes and proportions, but merely illustrate the contents of various embodiments of the invention. In addition, the number and size of meshes on the wire mesh of each conductive filter cell in the drawing do not reflect the actual number and proportion of meshes.
