Therefore, all the rotating shafts 2211 can be electrified only by connecting the connecting piece 2202 with the positive pole of the high-voltage power supply system.
In real life, once a relative motion relationship exists between two objects which are in contact with each other, the abrasion phenomenon is inevitable. Accordingly, in one embodiment, the dust scraper 2212 comprises a mounting frame 2204, two or four dust scraper bodies 2205 and a second resilient member 2206,
when the rotating shaft 2211 is provided only on one side of the dust scraper 2212, the number of the dust scraper bodies 2205 is two, and the mounting frame 2204 is provided with two or three mounting holes in the width direction thereof. When the mounting frame 2204 is provided with two mounting holes, the two dust scraping element bodies 2205 are slidably disposed on one side of the mounting frame 2204 facing the rotating shaft 2211 and are respectively located in the two mounting holes, one side of the dust scraping element body 2205 facing the rotating shaft 2211 is set to be arc-shaped corresponding to the outer diameter of the rotating shaft 2211 and is abutted to the outer surface of the rotating shaft, the second elastic element 2206 is disposed in the mounting holes, two ends of the second elastic element are abutted to the mounting frame 2204 and the dust scraping element bodies 2205, and in a natural state, the second elastic element 2206 bears pressure and is used for providing stress for always abutting the dust scraping element bodies 2205 and the rotating shaft 2211. When the mounting frame 2204 is provided with three mounting holes, wherein the second mounting hole (i.e. the middle mounting hole) is provided with the first conductive structure 2230, the two dust scraper bodies 2205 are slidably disposed on the side of the mounting frame 2204 facing the rotating shaft 2211 and are respectively located in the first and third mounting holes, the side of the dust scraper body 2205 facing the rotating shaft 2211 is set to be arc-shaped corresponding to the outer diameter of the rotating shaft 2211 and is abutted against the outer surface of the rotating shaft, the second elastic member 2206 is disposed in the mounting hole, and two ends of the second elastic member are respectively abutted against the mounting frame 2204 and the dust scraper body 2205, and in a natural state, the second elastic member 2206 bears pressure to provide a stress for always abutting against the rotating shaft 2211 to the dust scraper body 2205,
when the two sides of the dust scraping element 2212 are both provided with the rotating shafts 2211, the number of the dust scraping element bodies 2205 is four, the mounting frame 2204 is provided with three mounting holes along the width direction thereof, the second mounting hole is internally provided with the second conductive structure 2240, the four dust scraping element bodies 2205 are divided into two groups averagely, each group is two, the two groups of dust scraping element bodies 2205 are respectively arranged in the first and third mounting holes and are in sliding connection with the mounting frame 2204, one side of the dust scraping element body 2205 facing the rotating shaft 2211 is arranged in a circular arc shape corresponding to the outer peripheral surface of the rotating shaft 2211 and is abutted against the outer surface of the rotating shaft, the second elastic element 2206 is arranged in the mounting holes, two ends of the second elastic element are abutted against the two dust scraping element bodies 2205 respectively, and the second elastic element 2206 bears pressure in a natural state and is used for providing stress for the dust scraping element bodies 2205 and the rotating.
Therefore, even if the rotating shaft 2211 and the dust scraping element body 2205 are abraded, the rotating shaft 2211 and the dust scraping element body 2205 are always kept in interference under the action of the second elastic element 2206, and a good dust scraping effect is achieved.
In real life, when we energize positive plate 2210, it is positively charged on both sides, i.e., an electric field can be generated on both sides. Accordingly, in one embodiment, the dust removing unit 2200 includes two negative electrode plates 2220 and one positive electrode plate 2210, the two negative electrode plates 2220 being disposed at both sides of the positive electrode plate 2210, respectively. This creates an electric field on both sides of the positive plate 2210, which allows dust to be collected on both sides of the positive electrode to make full use of space.
In real life, when people treat garbage, if the garbage which is easy to generate dust is treated, the concentration value of the dust in tail gas is larger, and if the garbage which is not easy to generate dust is treated, the concentration value of the dust in the tail gas is smaller. If the intensity of the electric field between the positive and negative plates cannot be changed in real time at this time, the treatment is insufficient when the concentration value of the dust in the exhaust gas is large, thereby affecting the treatment effect.
According to the formula: e ═ U/d
Wherein E is the electric field intensity, U is the voltage value between the two polar plates, and d is the distance between the two polar plates.
It is known that the way of changing the electric field strength is usually to increase the voltage value between the two plates or/and to change the distance between the positive and negative plates.
Thus, in one embodiment, two negative plates 2220 are threaded onto drive shaft 2250 with the threads in opposite directions, and a dust concentration sensor 2260 and a blower 2270 are disposed within the flue. Specifically, the transmission shaft 2250 is connected to a driving device, such that when the dust concentration sensor 2260 detects that the concentration in the smoke is within a certain set range, the controller controls the fan 2270 to adjust the rotation speed of the fan 2270 to a value corresponding to the smoke concentration value, and at the same time, the controller controls the driving device to rotate the transmission shaft 2250, so as to drive the two negative plates 2220 to approach or separate from each other through the screw, thereby adjusting the distance between the negative plates 2220 and the positive plates 2210 to a value corresponding to the rotation speed of the fan 2270. For example, when the concentration of the dust in the exhaust gas is high, in order to improve the dust removing effect, the rotating speed of the fan 2270 needs to be reduced to improve the time for the exhaust gas to pass through the electrostatic dust removing device 2000, and the distance between the government polar plates is reduced to improve the dust removing effect. When the concentration value of the dust in the tail gas is smaller, the rotating speed of the fan 2270 can be increased to reduce the time of the tail gas passing through the electrostatic dust removal device 2000, so that the dust removal efficiency is improved.
The distance between the positive plate and the negative plate can be adjusted through the driving device through the structure, so that the electric field intensity is changed, and the dust removal efficiency is improved.
In one embodiment, the electrostatic precipitator 2000 further includes a dust collection box 2280, and the dust collection box 2280 is disposed at a lower side of the dust collection unit 2200 and disposed in a drawer structure with the housing 2100. Therefore, the dust collected by the dust collection unit 2200 can fall into the dust collection box 2280 under the action of gravity, and when the dust is accumulated to a certain degree, the dust inside can be disposed only by pulling out the dust collection box 2280, so that the dust collection device is convenient and practical and has a simple mechanism.
In one embodiment, one end or both ends of the rotating shaft 2211 are provided with a rotating shaft blade 2207, wherein the rotating shaft blade 2207 is configured to convert kinetic energy of the exhaust gas into kinetic energy of the rotating shaft 2211, so as to drive the rotating shaft 2211 to rotate, and specifically, after the exhaust gas enters the electrostatic precipitator 2000 from the flue, the kinetic energy of the exhaust gas is converted into kinetic energy of the rotating shaft 2211 under the action of the rotating shaft blade 2207, so as to drive the rotating shaft 2211 to rotate, without an additional driving device to drive the rotating shaft 2211 to rotate. It should be noted that, when the two ends of the rotating shaft 2211 are both provided with the rotating shaft blades 2207, the two rotating shaft blades 2207 are in the same direction, so as to drive the rotating shaft 2211 to rotate in the same direction.
The working principle of the invention is as follows:
in the process of treating the exhaust gas, the exhaust gas enters the electrostatic precipitator 2000 through the flue. The negative electrode of the electrostatic precipitator 2000 ionizes air molecules, so that dust in the exhaust gas is negatively charged in combination with electrons in the process of flowing to the positive electrode, so as to be attracted by the positive electrode, and then is deposited on the positive electrode 2210 by discharge. At this time, the dust deposited on the positive plate 2210, specifically, the dust deposited on the rotating shaft 2211, is separated from the surface of the rotating shaft 2211 under the action of the dust scraping member 2212 along with the rotation of the rotating shaft 2211, so as to achieve the purpose of timely cleaning the dust on the positive plate 2210, avoid the local breakdown phenomenon caused by dust collection, and further improve the dust collection efficiency.
