Description

Technical Field

[0001] This application relates to the field of electrostatic precipitator technology, and in particular to an electrostatic precipitator with intelligent high-temperature early warning and its early warning method. Background Technology

[0002] An electrostatic precipitator (ESP) is a highly efficient dust removal device that uses the principle of high-voltage electrostatic adsorption to remove dust from industrial flue gas. It is widely used in industries such as power, metallurgy, cement, and chemicals. An ESP mainly consists of a shell, a high-voltage power supply, a corona electrode, a collecting electrode, and auxiliary equipment. During operation, a high-voltage direct current is applied to the corona electrode, creating an extremely high electric field around it. Air molecules are ionized, generating a large number of free electrons and positive and negative ions. When dust-laden gas passes through the electric field, dust particles collide with the free electrons or ions, acquiring a negative charge. The charged dust particles then move towards the collecting electrode under the influence of the electric field and are adsorbed.

[0003] During prolonged use of an electrostatic precipitator (ESP), the dust layer adsorbed on the collecting electrodes gradually thickens, creating resistance. When high-voltage current passes through this dust layer, additional resistance heat is generated, especially when the dust has poor conductivity. When a large amount of dust suddenly appears in the gas being treated, the collecting electrodes of the ESP collect a significant amount of dust within a short time (one cleaning cycle). The high-voltage current passing through the dust layer generates substantial resistance heat. Over extended use, this resistance heat gradually increases, raising the temperature inside the ESP casing. Prolonged operation at high temperatures can cause thermal expansion and deformation of the corona electrode and collecting electrode, altering the electrode spacing and leading to uneven electric field or short circuits, ultimately damaging the ESP. Summary of the Invention

[0004] This application proposes an electrostatic precipitator with intelligent high-temperature early warning and its early warning method. It has the advantages of automatically detecting the internal temperature of the electrostatic precipitator shell and automatically issuing an early warning, which can solve the problem of the dust collecting electrode collecting a lot of dust in a short period of time, generating a lot of resistance heat, and causing equipment damage due to long-term high-temperature operation.

[0005] To achieve the above objectives, this application adopts the following technical solution: an electrostatic precipitator with intelligent high-temperature early warning and its early warning method, comprising a shell, a high-voltage power supply, a corona electrode, a support structure, and a dust collection electrode. The support structure includes: a support recess, fixedly installed at the bottom end of the inner wall of the shell; several support columns, equidistantly installed within the support recess, with their top ends abutting the bottom end of the dust collection electrode; a temperature sensing bladder, installed at the bottom end of the support recess, the temperature sensing bladder being filled with thermal expansion fluid; several sets of alarm devices for high-temperature warning are installed on the shell, the alarm devices including: a connecting pipe, both ends of which are fixedly inserted into the side walls of the shell; a connecting cylinder, fixedly connected above the connecting pipe and near both ends; a sliding column, slidably and sealingly installed within the connecting cylinder; a control switch, fixedly installed on the inner side wall of the shell; and a light alarm, fixedly installed on the outer side wall of the shell and electrically connected to the control switch closest to the inner wall of the shell.

[0006] Furthermore, there is a height difference between the installation heights of several control switches on the inner wall of the housing.

[0007] Furthermore, the temperature-sensing bladder is a bladder with a constant volume, and when the thermal expansion fluid inside the temperature-sensing bladder expands, the temperature-sensing bladder cannot be squeezed by the thermal expansion fluid to expand.

[0008] Furthermore, a dust removal device for vibrating and cleaning the dust collection electrode is provided between the sliding column and the dust collection electrode. The dust removal device includes: a support shaft, which is horizontally arranged above the connecting pipe and fitted with a support sleeve, the bottom end of which is fixedly installed on the inner wall of the housing; a gear, which is fixedly fitted on both ends of the support shaft; a rack, which is fixedly connected to the side of the sliding column near the dust collection electrode and meshes with the gear; and several striking mechanisms, which are fixedly fitted on the support shaft and arranged at equal intervals.

[0009] Furthermore, the striking mechanism includes a ring sleeve, a hinge shaft, and a striking block. One end of the ring sleeve is fixedly sleeved on the support shaft, and the other end of the ring sleeve is inserted with the hinge shaft. The striking block is hinged to the ring sleeve through the hinge shaft.

[0010] Furthermore, there is a certain angle difference between two adjacent rings on the support shaft, and the protruding positions of several rings are distributed in a spiral pattern.

[0011] Furthermore, the housing is provided with a cooling device for cooling the interior of the housing. The cooling device includes: a cooling tube, which is wound around the inner wall of the housing and evenly distributed; a pressure stabilizing pump, which is fixedly installed on the outer wall of the housing, and one end of the cooling tube is connected to the outlet of the pressure stabilizing pump; and a threaded column, which is inserted into the end of a support shaft and threadedly connected to the support shaft. The end of the threaded column presses against the connection between the cooling tube and the outlet of the pressure stabilizing pump.

[0012] Furthermore, a square hole is provided at one end of the threaded column near the inner wall of the housing, and a square rod is movably inserted into the square hole. The end of the square rod extending out of the square hole is fixedly installed on the inner wall of the housing.

[0013] Furthermore, when the support shaft moves upward, the rotation of the support shaft causes the threaded column to move inward, reducing the pressure of the threaded column on the cooling tube.

[0014] Furthermore, the following steps are included:

[0015] S1. When the temperature inside the housing rises, the thermal expansion fluid in the temperature sensing bag expands due to the increased temperature. The thermal expansion fluid pushes the sliding column upward. When the temperature inside the housing reaches a certain level, the sliding column hits the control switch on the side wall of the housing, thereby causing the control switch to activate the light alarm on the outside of the housing to sound an automatic alarm.

[0016] S2. When the temperature inside the shell gradually rises, the thermal expansion fluid in the temperature sensing bag expands, and the expanding thermal expansion fluid pushes the sliding column upward. The height to which the sliding column rises is different at different temperatures. At different temperatures, different sliding columns push up different control switches, and light alarms are emitted through different control switches to monitor the temperature range inside the shell in real time.

[0017] S3. When the temperature inside the shell rises, the thermal expansion fluid in the temperature sensing bag absorbs heat and expands, pushing the sliding column upward. The sliding column drives the rack to move synchronously, driving the gear to rotate. The gear drives the support shaft and the striking mechanism to rotate. The rotating striking mechanism hits the side wall of the dust collecting electrode, causing the dust collecting electrode to vibrate, thereby shaking off the dust on the dust collecting electrode.

[0018] S4. When the sliding column moves upward, it drives the rack to move synchronously. The rack drives the gear to rotate and the support shaft to rotate. The rotating support shaft causes the threaded column to move inward, thereby reducing the pressure of the threaded column end on the cooling tube and increasing the connection between the cooling tube and the outlet of the pressure stabilizing pump. The water velocity discharged by the pressure stabilizing pump through the cooling tube increases, thereby enhancing the heat dissipation effect of the cooling tube on the shell.

[0019] This application has the following beneficial effects:

[0020] 1. The electrostatic precipitator with intelligent high temperature early warning provided in this application works by the expansion of the thermal expansion fluid in the temperature sensing bag when the internal temperature of the shell rises. When a certain temperature is reached, the expanded thermal expansion fluid pushes the sliding column upward, causing the sliding column to push the control switch, thereby causing the light alarm to sound an alarm and reminding the staff to cool down the equipment.

[0021] 2. The electrostatic precipitator with intelligent high-temperature early warning provided in this application, when the thermal expansion liquid expands, pushes the sliding column upward, and the upward sliding column drives the rack to move synchronously, so that the rack drives the gear, support shaft and striking mechanism to rotate. The rotating striking mechanism intermittently strikes the dust collecting electrode, causing the dust collecting electrode to vibrate, thereby shaking off the dust collected on the dust collecting electrode, preventing the dust collecting electrode from having too much dust and generating too much resistance heat.

[0022] 3. The electrostatic precipitator with intelligent high temperature early warning provided in this application uses the expansion of thermal expansion liquid to push the sliding column upward. The upward sliding column drives the rack to move synchronously, thereby driving the gear and support shaft to rotate. Since the threaded column is restricted and cannot rotate, the threaded column moves into the support shaft, changing the degree of compression of the cooling tube by the threaded column. This increases the connection between the cooling tube and the outlet of the pressure stabilizing pump, increasing the water velocity discharged by the pressure stabilizing pump through the cooling tube. This enhances the heat dissipation effect of the cooling tube on the shell and prevents the shell from rapidly heating up in a short time, which could damage the equipment.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] Example 1

[0038] Please see Figures 1-10 An electrostatic precipitator with intelligent high-temperature early warning includes a housing 1, a high-voltage power supply 2, a corona electrode 3, a support structure 4, and a dust collection electrode 5. An air inlet 11 is fixedly installed at one end of the housing 1, and an air outlet 12 is fixedly installed at the other end of the housing 1. Several equidistant dust discharge ports 13 are fixedly installed at the bottom of the housing 1. The air inlet 11, air outlet 12, and dust discharge ports 13 are connected to the interior of the housing 1. The high-voltage power supply 2 is fixedly installed at the top of the housing 1, and the high-voltage power supply 2 seals the top of the housing 1. Several sets of support structures 4 are fixedly installed at the bottom of the inner wall of the housing 1. Each support structure 4 is provided with a dust collection electrode 5, and a set of corona electrodes 3 is provided between two adjacent dust collection electrodes 5. The bottom end of the corona electrode 3 is fixedly connected to the bottom end of the high-voltage power supply 2. The corona electrode 3 and the support structure 4 are electrically connected to the high-voltage power supply 2.

[0039] The support structure 4 includes a support recess 41, support columns 42, and a temperature sensing bag 43. The support recess 41 is fixedly installed at the bottom of the inner wall of the housing 1. Several support columns 42 are equidistantly installed inside the support recess 41, and the top of the support columns 42 abuts against the bottom of the dust collecting electrode 5. The bottom of the dust collecting electrode 5 is inserted into the support recess 41. The temperature sensing bag 43 is installed at the bottom of the support recess 41 and is filled with thermal expansion fluid. The top of the temperature sensing bag 43 contacts the bottom of the dust collecting electrode 5. Several sets of alarm devices for high temperature alarms are installed on the housing 1. The alarm devices include a connecting pipe 61, a connecting cylinder 62, a sliding column 63, a control switch 64, and a light. The alarm 65 has two ends of the connecting pipe 61 fixedly inserted into the side wall of the housing 1, and the connecting pipe 61 is connected to the temperature sensing bag 43 in the same support structure 4. A connecting tube 62 is fixedly connected above the connecting pipe 61 and near both ends. The connecting tube 62 is connected to the connecting pipe 61. A sliding column 63 is slidably and sealed inside the connecting tube 62. The top of the sliding column 63 extends out of the connecting tube 62. A control switch 64 is fixedly installed on the inner side wall of the housing 1. The control switch 64 is located directly above the sliding column 63. A light alarm 65 is fixedly installed on the outer side wall of the housing 1. The light alarm 65 is electrically connected to the control switch 64 closest to the inner wall of the housing 1.

[0040] When an electrostatic precipitator is operating and processing a large amount of gas in a short period of time, a large amount of dust will be adsorbed on the collecting electrode 5 in a short time. When a high-voltage current passes through the dust layer on the collecting electrode 5, a large amount of resistance heat will be generated. At this time, the temperature inside the housing 1 will rise, and the heat inside the housing 1 will be transferred to the temperature sensing bladder 43 in the support recess 41. This will cause the temperature of the thermal expansion fluid inside the temperature sensing bladder 43 to rise, and the thermal expansion fluid will expand. The expanded thermal expansion fluid in the temperature sensing bladder 43 will flow into the connecting cylinder 62 through the connecting pipe 61, causing the thermal expansion fluid to push the sliding column 63 upward. When the temperature inside the housing 1 reaches a certain level, the distance that the thermal expansion fluid pushes the sliding column 63 reaches its maximum, causing the sliding column 63 to hit the control switch 64 on the side wall of the housing 1. This will cause the control switch 64 to control the light alarm 65 on the outside of the housing 1 to emit a light alarm, automatically alarming and reminding the staff to cool down the equipment.

[0041] The installation heights of several control switches 64 on the inner wall of housing 1 differ. When the temperature inside housing 1 gradually increases, the thermal expansion fluid in the temperature sensing bladder 43 expands. The expanded thermal expansion fluid enters the connecting pipe 61 and the connecting cylinder 62, pushing the sliding column 63 upward. The sliding column 63 moves upward to different heights at different temperatures. At different temperatures, different sliding columns 63 push up different control switches 64, which then issue light alarms through different control switches 64 to monitor the temperature range inside housing 1 in real time.

[0042] The temperature sensing bladder 43 is a bladder with a constant volume. When the thermal expansion fluid inside the temperature sensing bladder 43 expands, the temperature sensing bladder 43 cannot be squeezed by the thermal expansion fluid to prevent the temperature inside the shell 1 from rising. When the thermal expansion fluid expands, it cannot push the sliding column 63 to move upward, thereby causing the sliding column 63 to lose the function of squeezing control switch 64.

[0043] The working principle of Embodiment 1 of the present invention is as follows:

[0044] Please see Figures 1-10 When an electrostatic precipitator is in operation and processes a large amount of gas in a short period of time, a large amount of dust will be adsorbed on the dust collecting electrode 5 in a short time. When the high voltage current passes through the dust layer on the dust collecting electrode 5, a lot of resistance heat will be generated. At this time, the temperature inside the shell 1 will rise. The heat inside the shell 1 will be transferred to the temperature sensing bladder 43 in the support recess 41, which will raise the temperature of the thermal expansion fluid in the temperature sensing bladder 43 and cause the thermal expansion fluid to expand. The expanded thermal expansion fluid in the temperature sensing bladder 43 will flow into the connecting cylinder 62 through the connecting pipe 61, which will push the sliding column 63 upward. When the temperature inside the shell 1 reaches a certain height, the distance that the thermal expansion fluid pushes the sliding column 63 reaches its maximum, so that the sliding column 63 hits the control switch 64 on the side wall of the shell 1. This will cause the control switch 64 to control the light alarm 65 on the outside of the shell 1 to emit a light alarm, automatically alarm, and remind the staff that the equipment needs to be cooled down.

[0045] As the temperature inside the housing 1 gradually rises, the thermal expansion fluid in the temperature sensing bladder 43 expands. The expanded thermal expansion fluid enters the connecting pipe 61 and the connecting cylinder 62, pushing the sliding column 63 upward. The sliding column 63 moves upward to different heights at different temperatures. At different temperatures, different sliding columns 63 push up different control switches 64, which then issue light alarms and monitor the temperature range inside the housing 1 in real time.

[0046] Example 2

[0047] Example 2 is a further improvement based on Example 1.

[0048] Unlike Example 1, please refer to Figures 1-10A dust removal device for vibrating and cleaning the dust collection electrode 5 is provided between the sliding column 63 and the dust collection electrode 5. The dust removal device includes a support shaft 71, a gear 72, a rack 73, and a striking mechanism 74. The support shaft 71 is horizontally positioned above the connecting pipe 61, and a support sleeve is movably sleeved on the support shaft 71. The bottom end of the support sleeve is fixedly installed on the bottom end of the inner wall of the housing 1. Gears 72 are fixedly sleeved at both ends of the support shaft 71. A rack 73 is fixedly connected to the side of the sliding column 63 near the dust collection electrode 5. The rack 73 meshes with the gear 72 (the diameter of the gear 72 is small, and the rack 73 can drive the gear 72 to rotate one revolution with a small upward movement). Several equally spaced striking mechanisms 74 are fixedly sleeved on the support shaft 71. When the striking mechanism 74 rotates with the support shaft 71, it strikes the dust collecting electrode 5. As the temperature inside the housing 1 rises, the thermal expansion fluid in the temperature sensing bladder 43 absorbs heat and expands. The expanded thermal expansion fluid in the temperature sensing bladder 43 flows into the connecting cylinder 62 through the connecting pipe 61, pushing the sliding column 63 upward. The upward sliding column 63 drives the rack 73 to move synchronously, and the upward rack 73 drives the gear 72 to rotate, causing the gear 72 to drive the support shaft 71 and the striking mechanism 74 to rotate. The rotating striking mechanism 74 strikes the side wall of the dust collecting electrode 5, causing the dust collecting electrode 5 to vibrate, thereby shaking off the dust on the dust collecting electrode 5 and preventing the dust collecting electrode 5 from having too much dust and generating too much resistance heat.

[0049] The striking mechanism 74 includes a ring 741, a hinge shaft 742, and a striking block 743. One end of the ring 741 is fixedly sleeved on the support shaft 71, and the other end of the ring 741 is inserted into the hinge shaft 742. The striking block 743 is hinged to the ring 741 through the hinge shaft 742. When the support shaft 71 drives the ring 741 to rotate, the ring 741 drives the striking block 743 to rotate synchronously. When the striking block 743 passes the top of the support shaft 71, under the action of gravity, the striking block 743 rotates around the hinge shaft 742 and strikes the side wall of the dust collecting electrode 5, causing the dust collecting electrode 5 to vibrate.

[0050] There is a certain angle difference between two adjacent rings 741 on the support shaft 71, and the protruding positions of several rings 741 are distributed in a spiral pattern; this ensures that the gravity of several striking mechanisms 74 on the support shaft 71 is evenly distributed, and prevents the protruding parts of the rings 741 from being on one side, which would cause the support shaft 71 to be subjected to greater force on one side.

[0051] The housing 1 is equipped with a cooling device for cooling the interior of the housing 1. The cooling device includes a cooling pipe 81, a pressure stabilizing pump 82, and a threaded column 83. The cooling pipe 81 is wound around the inner wall of the housing 1 and is evenly distributed on the inner wall. The pressure stabilizing pump 82 is fixedly installed on the outer wall of the housing 1. One end of the cooling pipe 81 penetrates the side wall of the housing 1 and is connected to the outlet of the pressure stabilizing pump 82. The threaded column 83 is inserted into the end of the support shaft 71 and is threadedly connected to the support shaft 71. The end of the threaded column 83 presses against the connection between the cooling pipe 81 and the outlet of the pressure stabilizing pump 82. A square hole is opened at the end of the threaded column 83 near the inner wall of the housing 1, and a square rod is movably inserted into the square hole. The end of the square rod extending out of the square hole is fixedly installed on the inner wall of the housing 1. During operation, the inlet pipe of the pressure stabilizing pump 82 draws in external cooling water, and the cooling water flows out from the other end of the cooling pipe 81 and cools the interior of the housing 1. As the temperature rises, the thermal expansion fluid inside the temperature sensing bladder 43 absorbs heat and expands. The expanding thermal expansion fluid flows into the connecting cylinder 62 through the connecting pipe 61, pushing the sliding column 63 upward. The upward sliding column 63 drives the rack 73 to move synchronously, and the upward-moving rack 73 drives the gear 72 to rotate. The gear 72 drives the support shaft 71 to rotate synchronously. Since the support shaft 71 is threadedly connected to the threaded column 83, and the threaded column 83 is restricted from rotating by the square rod, the rotating support shaft 71 causes the threaded column 83 to move into the support shaft 71. This reduces the pressure of the end of the threaded column 83 on the cooling pipe 81, increasing the connection between the cooling pipe 81 and the outlet of the pressure stabilizing pump 82. Because the pressure stabilizing pump 82 outputs stable pressure, the water velocity discharged by the pressure stabilizing pump 82 through the cooling pipe 81 increases, thereby enhancing the heat dissipation effect of the cooling pipe 81 on the shell 1 and preventing the shell 1 from heating up rapidly in a short time, which could damage the equipment.

[0052] During the upward movement and rotation of the support shaft 71, the rotation of the support shaft 71 causes the threaded column 83 to move inward into the support shaft 71, reducing the pressure of the threaded column 83 on the cooling pipe 81; when the internal temperature of the shell 1 rises, it ensures that the pressure of the threaded column 83 on the cooling pipe 81 is reduced, thereby increasing the amount of water passing through the cooling pipe 81 and enhancing the cooling effect inside the shell 1.

[0053] The working principle of Embodiment 2 of the present invention is as follows:

[0054] Please see Figures 1-10 As the temperature inside the housing 1 rises, the thermal expansion fluid inside the temperature sensing bladder 43 absorbs heat and expands. The expanded thermal expansion fluid inside the temperature sensing bladder 43 flows into the connecting cylinder 62 through the connecting pipe 61, pushing the sliding column 63 upward. The upward sliding column 63 drives the rack 73 to move synchronously, and the upward rack 73 drives the gear 72 to rotate, causing the gear 72 to drive the support shaft 71 and the striking mechanism 74 to rotate. The rotating striking mechanism 74 impacts the side wall of the dust collecting electrode 5, causing the dust collecting electrode 5 to vibrate, thereby shaking off the dust on the dust collecting electrode 5 and preventing the dust collecting electrode 5 from having too much dust and generating too much resistance heat.

[0055] During operation, the inlet pipe of the pressure stabilizing pump 82 draws in external cooling water, which flows out from the other end of the cooling pipe 81. The temperature inside the housing 1 rises, causing the thermal expansion fluid in the temperature sensing bladder 43 to absorb heat and expand. This expanding fluid flows through the connecting pipe 61 into the connecting cylinder 62, pushing the sliding column 63 upwards. The upward-moving sliding column 63 drives the rack 73 to move synchronously, and the upward-moving rack 73 drives the gear 72 to rotate. The gear 72 then drives the support shaft 71 to rotate synchronously. Because the support shaft 71 and the screw... The threaded column 83 is connected by a thread, and the threaded column 83 is restricted from rotating by the square rod. The rotating support shaft 71 causes the threaded column 83 to move inward, thereby reducing the pressure of the end of the threaded column 83 on the cooling pipe 81 and increasing the connection between the cooling pipe 81 and the outlet of the pressure stabilizing pump 82. Since the pressure stabilizing pump 82 outputs stable pressure, the water velocity discharged by the pressure stabilizing pump 82 through the cooling pipe 81 increases, thereby enhancing the heat dissipation effect of the cooling pipe 81 on the shell 1 and preventing the shell 1 from heating up rapidly in a short time, which could damage the equipment.

[0056] The early warning method for electrostatic precipitators with intelligent high-temperature warning includes the following steps:

[0057] S1. The temperature inside the housing 1 rises, and the heat inside the housing 1 is transferred to the temperature sensing bladder 43 inside the support recess 41, causing the temperature of the thermal expansion fluid inside the temperature sensing bladder 43 to rise. The thermal expansion fluid expands and flows into the connecting cylinder 62 through the connecting pipe 61, causing the thermal expansion fluid to push the sliding column 63 upward. When the temperature inside the housing 1 reaches a certain height, the distance that the thermal expansion fluid pushes the sliding column 63 reaches its maximum, causing the sliding column 63 to hit the control switch 64 on the side wall of the housing 1. This causes the control switch 64 to control the light alarm 65 on the outside of the housing 1 to emit a light alarm, automatically alarming and reminding the staff that the equipment needs to be cooled down.

[0058] S2. When the temperature inside the housing 1 gradually rises, the thermal expansion fluid in the temperature sensing bladder 43 expands. The expanded thermal expansion fluid enters the connecting pipe 61 and the connecting cylinder 62, pushing the sliding column 63 upward. The sliding column 63 moves upward to different heights at different temperatures. At different temperatures, different sliding columns 63 push up different control switches 64, and light alarms are issued through different control switches 64 to monitor the temperature range inside the housing 1 in real time.

[0059] S3. As the temperature inside the housing 1 rises, the thermal expansion fluid inside the temperature sensing bladder 43 absorbs heat and expands. The expanded thermal expansion fluid inside the temperature sensing bladder 43 flows into the connecting cylinder 62 through the connecting pipe 61. When the sliding column 63 moves upward, the upward sliding column 63 drives the rack 73 to move synchronously. The upward rack 73 drives the gear 72 to rotate, which in turn drives the support shaft 71 and the striking mechanism 74 to rotate. The rotating striking mechanism 74 impacts the side wall of the dust collecting electrode 5, causing the dust collecting electrode 5 to vibrate, thereby shaking off the dust on the dust collecting electrode 5 and preventing the dust collecting electrode 5 from having too much dust and generating too much resistance heat.

[0060] S4. When the sliding column 63 moves upward, the upward sliding column 63 drives the rack 73 to move synchronously, and the upward rack 73 drives the gear 72 to rotate. The gear 72 drives the support shaft 71 to rotate synchronously. Since the support shaft 71 is threadedly connected to the threaded column 83, and the threaded column 83 is restricted from rotating by the square rod, the rotating support shaft 71 causes the threaded column 83 to move inward, thereby reducing the pressure of the end of the threaded column 83 on the cooling pipe 81 and increasing the connection between the cooling pipe 81 and the outlet of the pressure stabilizing pump 82. Since the pressure stabilizing pump 82 outputs stable pressure, the water velocity discharged by the pressure stabilizing pump 82 through the cooling pipe 81 increases, thereby enhancing the heat dissipation effect of the cooling pipe 81 on the shell 1 and preventing the shell 1 from heating up rapidly in a short time, which could damage the equipment.

6. The early warning method for an electrostatic precipitator with intelligent high-temperature early warning according to claim 5, characterized in that: Includes the following steps: S1. When the temperature inside the housing (1) rises, the temperature of the thermal expansion fluid in the temperature sensing bag (43) rises and expands. The thermal expansion fluid pushes the sliding column (63) upward. When the temperature inside the housing (1) reaches a certain height, the sliding column (63) hits the control switch (64) on the side wall of the housing (1), thereby causing the control switch (64) to control the light alarm (65) on the outside of the housing (1) to emit a light alarm and automatically alarm. S2. When the temperature inside the shell (1) gradually rises, the thermal expansion fluid in the temperature sensing bag (43) expands. The expanded thermal expansion fluid pushes the sliding column (63) upward. The height of the sliding column (63) is different when the temperature is different. At different temperatures, different sliding columns (63) push up different control switches (64). Light alarms are issued through different control switches (64) to monitor the temperature range inside the shell (1) in real time. S3. When the temperature inside the housing (1) rises, the thermal expansion liquid inside the temperature sensing bag (43) absorbs heat and expands, pushing the slide column (63) to move upward. The slide column (63) drives the rack (73) to move synchronously, driving the gear (72) to rotate. The gear (72) drives the support shaft (71) and the knocking mechanism (74) to rotate. The rotating knocking mechanism (74) hits the side wall of the dust collecting electrode (5), causing the dust collecting electrode (5) to vibrate, thereby shaking off the dust on the dust collecting electrode (5). S4. When the sliding column (63) moves upward, it drives the rack (73) to move synchronously. The rack (73) drives the gear (72) to rotate and the support shaft (71) to rotate. The rotating support shaft (71) causes the threaded column (83) to move into the support shaft (71), thereby reducing the pressure of the end of the threaded column (83) on the cooling tube (81), increasing the connection between the cooling tube (81) and the outlet of the pressure pump (82), and increasing the water speed discharged by the pressure pump (82) through the cooling tube (81), thereby enhancing the heat dissipation effect of the cooling tube (81) on the shell (1).
