The helix is to the tensioning force control requirement strict when the installation, often be difficult to control when on-the-spot installation, when the tensioning force is too big, the helix receives periodic stress easily and the cracked condition appears, otherwise, when the tensioning force is too little, the helix can't install in braced frame firmly, leads to the helix to take place the wobbling condition under the effect of electric field wind speed (refer to the flow velocity of flue gas in the electric precipitation electric field), and then causes the difference of polar distance deviation, influences dust collection efficiency. In addition, when two types of linear narrow pulse power supplies with 30 mu s level are matched, the peak voltage is often difficult to reach more than 140kV of the design requirement, the output current is difficult to reach more than 200A of the design requirement, the dust collection effect of the pulse power supplies is inhibited, and the problem of insufficient matching exists. In view of the foregoing, a technical solution is needed to avoid the breakage or swing caused by the corona sealing and the unstable structure generated by the dust accumulation of the polar lines, and meanwhile, the dust collector has good adaptability to the pulse power supply, so as to improve the dust collection efficiency.

Detailed Description
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
According to an embodiment of the present application, a cathode ray apparatus 5 in the present embodiment, the cathode ray apparatus 5 being used for a dust removing device, the cathode ray apparatus 5 in the present application including a support part 1 and a discharge body 2, is described with reference to fig. 1 and 2.
Specifically, as shown in fig. 1, the support portion 1 has a columnar shape, and a plurality of discharge bodies 2 are welded to the support portion 1. The discharge body 2 is a spherical discharge body 2. The spherical discharge body 2 means that the voltammetry curve of the discharge body 2 can slowly and stably rise to a peak value.
More specifically, referring to fig. 2, the spherical discharge body 2 includes a body portion 21 and a corona head 22, and the body portion 21 is cylindrical and extends in a straight line. One end surface of the body 21 is welded to the support 1. The corona head 22 is provided on the other end surface of the body portion 21 on the side away from the supporting portion 1.
However, referring to fig. 2, a circular pad 211 is formed at the end surface where the body portion 21 and the support portion 1 are welded, and the pad 211 is welded to the support portion 1 to increase the welding area and increase the connection strength of the discharge body 2 and the support portion 1. It is to be understood that the end face of the body 2 may be directly welded to the support 1 without adding the pad 211. The discharge body structure in the present embodiment can significantly increase the soldering strength compared to the manner in which the pads 211 are not added.
The corona head 22 is spherical, and the spherical diameter of the corona head 22 is larger than the radial dimension of the body part 21 so as to ensure that the discharge point of the discharge body 2 is always positioned at the position of the spherical corona head 22. The corona head 22 is a member capable of forming a corona phenomenon.
For example, the difference between the ball diameter of the corona head 22 and the radial dimension of the body portion 21 is 0.2mm to 0.5mm. Within the above range, the corona head 22 can be effectively ensured to be a discharge point of the discharge body 2. If the discharge point of the discharge body 2 is out of the above range, the discharge point may be easily shifted.
In the dust removal, the spherical corona head 22 is used as a convex point of the discharge body 2, and can form a stable high-voltage electric field, so that the spherical corona head can be ionized with dust to separate the dust in the air flow of the dust removal device. The separated dust is adsorbed by the electric field.
As will be appreciated by those skilled in the art, the soldering position of the body portion 21 and the support portion 1 will accumulate some solder, and the solder is located at the end of the body portion 21 remote from the corona head 22, so that the protrusion of the solder is negligible and will not form a discharge point of the discharge body 2. In addition, the raised portions of the solder may be removed by a grinding process.
According to the cathode ray device 5 of the embodiment of the invention, by directly welding one end face of the body part 21 to the supporting part 1, the situation that the body part and the supporting part are not adhered and the flatness is offset in the bending process of the wavy line body part is effectively avoided, the vibration force transmission attenuation problem caused by the closed loop space formed by the body part and the supporting part is solved, and the corona sealing phenomenon is avoided.
Meanwhile, the supporting part 1 is cylindrical and can be directly welded on the mounting bracket 4, so that the existing mounting mode is effectively simplified, the problem that the spiral line is broken or swings due to overlarge or overlarge tension force is avoided, the difference in polar distance is further reduced or avoided, and the dust removal efficiency is ensured.
Further, a spherical discharge body is constituted by providing a cylindrical support portion 1, a cylindrical discharge body portion 21, and a spherical corona head 22 such that the spherical diameter of the corona head 22 is larger than the radial dimension of the body portion 21. The discharge body can form a more stable electrostatic field through spherical discharge.
Meanwhile, compared with the cathode line structure with a wave shape and a spiral structure, the spherical corona head 22 has low corona onset voltage and high current density. After corona discharge is performed to form a charge body, electric field energy can be distributed on the surface of the sphere, and the electric field energy stored in the sphere is also existed in the sphere, so that compared with other lines, the electric field energy stored in the sphere is more than that stored in other lines, and the electric field energy on the surface of the spherical corona head can be supplemented by the electric field energy, so that the spherical corona head can discharge more stably than other structures, and further, the discharge of the discharge body is more stable.
In addition, a concave ring transition part 23 is arranged between the corona head 22 and the body part 21, a self-cleaning ash falling angle is formed by setting a certain concave ring angle alpha, and the transmission of vibration force is further amplified, so that the cathode wire always keeps the spherical corona head 22 clean by self ash falling and external vibration force in the working process, and the discharge capacity is ensured.
In one example, the axial length of the body portion 21 is 5mm-50mm. The axial length of the body 21 can be set by a person skilled in the art according to the concentration of dust.
In some embodiments, referring to fig. 1 and 2, a transition 23 is provided where the body portion 21 joins the corona head 22, the transition 23 having an inner diameter dimension at least less than the radial dimension of the corona head 22. The generator thus arranged can ensure that the spherical corona head 22 of the generator discharges, thereby avoiding the occurrence of discharge point deviation caused by the radial dimension of the transition part 23 exceeding the radial dimension of the corona head 22.
In some embodiments, the cathode ray tube means 5 can be driven to vibrate by a rapping device in the dust removal apparatus. The specific kind of rapping device in the dust removal device is known in the art and can be chosen by the person skilled in the art. The transition portion 23 has a first cambered surface 231 recessed inward, and the first cambered surface 231 is recessed from the outside toward the inside in the radial direction of the body portion 21.
Specifically, the transition portion 23 is a concave arc structure, and the inner diameter of the transition portion 23 is gradually reduced and then gradually increased from a side close to the corona head 22 to a side close to the body portion 21 in the axial direction of the body portion 21. The outer surface of the transition portion 23 is a first cambered surface 231, and the two ends of the first cambered surface 231 in the axial direction of the body portion 21 are respectively connected with the corona head 22 and the body portion 21. The first arc 231 smoothly transitions with the position where the corona head 22 is connected. For example, the location where the transition 23 connects with the corona head 22 may be smoothly transitioned through a grinding process to prevent the discharge point from shifting.
When the discharge body 2 vibrates under the drive of the rapping device, dust adhering to the corona head 22 and the transition part 23 can be shaken off rapidly.
The discharge body 2 that sets up from this is through setting up the outer peripheral face and be the transition portion 23 of first cambered surface 231 to the mode of connecting corona head 22 and body portion 21, with make corona head 22 can form smooth connection with body portion 21, can avoid corona head 2 direct and body portion 21 welded mode and form gap or bead of being connected like this, and then avoided the dust to pile up the gap or bead position at the junction, thereby can prevent effectively that the dust from piling up, and then prevent that discharge body 2 from laying dust and causing corona confined condition to take place, improve dust collection efficiency.
Meanwhile, the structure of the discharge body 2 is simpler, and the vibration force transmission is prevented from being influenced so as to prevent the dust accumulation of the discharge body 2.
In some embodiments, as shown in fig. 1 and 2, the connection position of the transition portion 23 and the body portion 21 has an arc to form a second arc 232, and the corona head 22 is connected to the body portion 21 in a smooth transition manner through the first arc 231 and the second arc 232.
Specifically, the position where the transition portion 23 is connected to the body portion 21 in the axial direction may be configured as an arc surface by grinding to form the second arc surface 232.
During the shaking process, dust from the second arc 232 can slip down the arc. This can further prevent dust from accumulating in this position.
In a specific embodiment, an included angle between a line connecting the arc centers of the first arc surface 231 and the second arc surface 232 and the radial direction of the body part is alpha, and alpha is more than or equal to 30 degrees and less than or equal to 60 degrees.
Specifically, referring to fig. 2, the first arc 231 is recessed toward a direction approaching the central axis of the body portion 21, and the second arc 232 is protruded toward a direction away from the central axis of the body portion 21 to form an approximately S-shaped sectional shape. The center of the first arc 231 and the center of the second arc 232 refer to the center of the circle where the first arc 231 and the second arc 232 are located.
When α is too small, the difference in radial dimension between the corona head 21 and the body portion 22 is small, which easily affects the discharge performance of the corona head 22, and when α is too large, the recess of the transition portion 23 is too deep, which easily causes the occurrence of dust deposition. Thus, when α is within the above range, dust on the discharge body 2 is most easily shaken off, thereby improving the ash shaking efficiency.
Further, α=45° to achieve the optimum ash-shaking effect.
In a particular embodiment, the radius r1 of the first arcuate surface 231 is sized to be the same as the radius r2 of the second arcuate surface 232.
Specifically, referring to fig. 2, the center of the first arc 231 is located outside the discharge body 2, and the center of the second arc 232 is located inside the discharge body 2. The dimensions of the first arc surface 231 and the second arc surface 232 thus provided can simplify the machining mode of the discharge body 2, and at the same time, by means of making r1=r2, the rapping force of the rapping device can be utilized to the greatest extent, thereby further improving the ash shaking efficiency.
For example, the dimensions of r1 and r2 are 0.2mm to 1.5mm. When the sizes of r1 and r2 are too small, the ash shaking effect cannot be ensured, and when the sizes of r1 and r2 are too large, the depth of the transition portion 23 in the radial direction is too deep, so that the occurrence of the condition that the ash shaking effect is not ideal is easily caused.
In other embodiments of the present invention, a dust removing apparatus comprising the above cathode ray device 5 is provided. With reference to fig. 3, the apparatus includes a front electric field, an intermediate electric field, and a rear electric field, which are sequentially arranged in a direction in which the flue gas circulates, and the cathode wire device 5 is arranged in the rear electric field.
When the electric field dust is removed, the spherical discharge body 2 can be matched with the dust characteristics in the electric field, so that the characteristics of low dust density and high specific resistance of dust in the electric field can be effectively aimed at, and higher secondary voltage and lower secondary current can be provided to remove the dust in the electric field.
It will be appreciated that the cathode ray tube apparatus 5 of the present invention may also be used for medium electric fields. However, when the cathode ray device 5 is used for the final electric field, the situation that the conventional waveform line and spiral line cathode ray structure cannot meet the secondary current and secondary voltage required by dust removal can be aimed, so that the dust removal efficiency of the final electric field is improved more remarkably.
In addition, the cathode line structure of the invention can be better matched with a pulse power supply in dust removal equipment, and can stably form secondary current and secondary voltage which meet the requirement of dust removal, so as to obviously improve the dust removal efficiency. Meanwhile, the spherical corona head 22 also has electric field energy inside the sphere, so that the discharge efficiency is improved, and the energy consumption ratio of the pulse power supply is reduced.
The dust removing device also comprises a vibrating device which can drive the cathode wire device to perform vibration dust removal.
In some embodiments, referring to fig. 1 and 3, the dust removing apparatus includes a plurality of anode plates 3, and the cathode wire device 5 is disposed between two adjacent anode plates 3 through a mounting bracket 4. The plurality of discharge bodies 2 of the cathode line device 5 are arranged on two radial sides of the supporting part 1, adjacent discharge bodies 2 are arranged at intervals in the axial direction of the supporting part 1, and the discharge bodies 2 extend along the direction parallel to the anode plate 3.
Specifically, the axially adjacent discharge bodies 2 extend in a direction away from each other in the radial direction, each discharge body 2 is disposed substantially in a direction parallel to the anode plate, and the spacing of the adjacent discharge bodies 2 in the axial direction of the support portion 1 is uniform, thereby making the field strength of the cathode wire assembly 5 more uniform. The cathode ray device 5 thus provided can prevent the discharge body 2 from forming field strength overlapping during discharge, thereby interfering with the dust removal effect.
The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present invention and its core ideas.
