It will be appreciated that the thermoelectric converter 30 is disposed around the outer surface of the annular sidewall of the dust-removing chamber 201. The thermoelectric converter 30 includes a thermoelectric device 301 and an annular heat sink 300. The thermoelectric device 301 is located between the dust-removing cavity 201 and the annular heat sink 300. The thermoelectric device 301 is electrically connected to the intake detector 106 and the exhaust detector 108 by wires. Specifically, the thermoelectric device 301 includes a first heat conducting substrate 302, a first electrode layer 303, a p-type thermoelectric leg 304, an n-type thermoelectric leg 305, a second electrode layer 306, and a second heat conducting substrate 307, which are sequentially stacked in a direction along the annular heat sink 300 to the outer surface of the annular side wall of the dust-removing cavity 201. The p-type thermoelectric legs 304 and the n-type thermoelectric legs 305 are arranged alternately and connected to the adjacent p-type thermoelectric leg 304 or n-type thermoelectric leg 305 through the first electrode layer 303 and the second electrode layer 306, respectively. The thermoelectric device 301 converts the temperature difference between the outer surface of the annular sidewall of the dust-removing cavity 201 and the annular heat sink 300 into electric energy and supplies power to the intake detector 106 and the exhaust detector 108. In other embodiments, the number of the thermoelectric devices 301 is plural (two or more). The plurality of thermoelectric devices 301 are combined in series, parallel, or series-parallel.
The annular heat sink 300 is disposed around the outer surface of the first heat conductive substrate 302 to fix the thermoelectric device 301 and the dust-removing cavity 201. The ring-shaped heat sink 300 includes at least two fins 300 a.
According to the triboelectric-heating electric-dust-removal detection equipment 1 and the triboelectric-heating electric-dust-removal detection method, the medium particles 206 are accommodated in the dust-removal cavity 201, the medium particles 206 and the waste particles 205 rub with each other to generate high-voltage static electricity, and/or the waste particles 205 rub with the cylindrical electrode 204 in the dust-removal cavity 201 to generate high-voltage static electricity, and the charged waste particles 205 are adsorbed to the cylindrical electrode 204 under the action of the static electricity. Therefore, the effective adsorption of the waste particles 205 in the waste gas is realized under the double actions of electrostatic adsorption and physical adsorption, and the dust removal effect is good. Meanwhile, the thermoelectric device 301 converts the temperature difference between the outer surface of the annular side wall of the dust removal cavity 201 and the annular radiator 300 into electric energy, and the heat energy of the waste gas is recycled, so that the air inlet detector 106 and the exhaust detector 108 are powered, energy is saved, and the environment is protected. In addition, the air inlet detector 106 and the exhaust detector 108 are arranged at the air inlet pipeline 101 and the exhaust pipeline 109 of the dust removal cavity 201, so that the adsorption and real-time detection of the waste particles 205 are synchronously performed, secondary pollution is avoided, and high-standard emission is realized.
Specifically, the intake airflow 202 enters the inside of the dust removing cavity 201 from the intake duct 101 and spreads inside the dust removing cavity 201. The waste particles 205 contained in the inlet air stream 202 rub against the media particles 206 in the dust extraction chamber 201 and/or the waste particles 205 rub against the cylindrical electrode 204 in the dust extraction chamber 201 to generate a high voltage electric field, thereby charging the waste particles 205. Due to the friction, a high voltage electric field is formed inside the dust removing chamber 201. At this time, the temperature inside the dust removing chamber 201 rises. The intake airflow 202 itself may also carry heat. Therefore, a temperature difference exists between the outer surface of the annular sidewall of the dust removing cavity 201 and the annular heat sink 300. The thermoelectric converter 30 converts the temperature difference between the outer surface of the annular sidewall of the dust-removing chamber 201 and the annular heat sink 300 into electric energy by the thermoelectric device 301, thereby supplying power to the intake detector 106 and the exhaust detector 108 and recycling the heat energy of the exhaust gas. Meanwhile, under the driving of the cylinder rotating shaft 103, the dust-removing cavity 201 rotates, so that the waste particles 205 and the medium particles 206 are mixed more uniformly.
Under the action of the high-voltage electric field, the waste particles 205 are deeply ionized into charged ions and adsorbed by the cylindrical electrode 204 in the dust-removing cavity 201. The charge varies due to the different mass of the waste particles 205. In this way, the waste particles 205 with different charge amounts can still be adsorbed onto the cylindrical electrode 204 under the action of the high-voltage electric field, and effective adsorption of the waste particles 205 is realized. The triboelectric-heating electric dust removal detection equipment 1 of the embodiment of the invention utilizes the DC/DC boosting module to perform electric output management on the thermoelectric device 301 so as to better match the voltage input requirements of the air inlet detector 106 and the air outlet detector 108 of different types.
In addition, the friction electric heating electric dust removal detection equipment 1 further comprises a cylinder rotating shaft trigger device 110, and the cylinder rotating shaft trigger device 110 is electrically connected with the cylinder rotating shaft 103. The intake detector 106 detects a constituent parameter of the intake airflow 202 and the exhaust detector 108 detects a constituent parameter of the exhaust airflow 207. The constituent parameters of the intake airflow 202 are compared to the constituent parameters of the exhaust airflow 207 and fed back to the barrel spindle trigger assembly 110. If the component parameters of the exhaust airflow 207 do not meet the standard, the cylinder rotating shaft triggering device 110 triggers the cylinder rotating shaft 103 to continue to drive the dust removal cavity 201 to rotate, and the exhaust airflow 207 is discharged until the components of the exhaust airflow 207 meet the discharge standard, so that pollution-free discharge is achieved. When the dust removing cavity 201 rotates, the dust removing cavity 201 is driven to rotate by the cylinder rotating shaft 103, so that friction between the waste particles 205 and the medium particles 206 in the dust removing cavity 201 and friction between the waste particles 205 and the cylinder electrode 204 are stronger, ionization efficiency and electrostatic induction rate are improved, and adsorption of the cylinder electrode 204 to the waste particles 205 is accelerated.
Here, the intake air detecting probe 105 is of the same type as the exhaust air detecting probe 107. The air inlet detection probe 105 and the exhaust detection probe 107 may be one or more of a temperature and humidity detector, a chemical composition analysis detector, and a micro-nano particle size detector. The inlet air detection probe 105 and the outlet air detection probe 107 may be used to detect one or more of temperature, humidity, chemical composition, and micro-nano particle size.
Referring again to fig. 1, in some embodiments, the dust removal device includes a fan cylinder screen 102 disposed downstream of the air intake duct 101. The fan cylinder screen 102 is disposed within the dust extraction chamber 201.
The dust removing device is cylindrical, and the air inlet duct 101 is also cylindrical. One end of the air inlet pipe 101 is arranged outside the dust removing cavity 201, and the other end is connected with the upper bottom of the fan-shaped cylinder filter screen 102. The lower bottom of the fan-shaped cylindrical filter screen 102 faces the interior of the dust-removing cavity 201. The diameter of the upper base of the fan cylinder screen 102 is smaller than the diameter of the lower base. As such, when the intake airflow 202 enters the dust removing chamber 201 along the intake duct 101, on the one hand, the waste particles 205 with larger diameters are filtered by the fan cylinder screen 102 and do not enter the dust removing chamber 201, reducing the amount of waste particles 205 entering the interior of the dust removing chamber 201. On the other hand, the smaller diameter waste particles 205 are guided by the fan cylinder screen 102, and the incoming airflow 202 is more easily diffused in the dust-removing chamber 201, so that the smaller diameter waste particles 205 are uniformly mixed with the media particles 206.
The air inlet duct 101, the fan-shaped cylinder filter screen 102, the cylinder rotating shaft 103, the fixing bracket 104, and the air outlet duct 109 may be made of the same material, and may be made of stainless steel (e.g., 304 stainless steel) or copper.
The material of the dust-removing cavity 201 is an insulating material with high mechanical properties, such as an insulating polymer material, an insulating bakelite, or an insulating ceramic. Since the waste particles 205 and the media particles 206 rotate at a high speed inside the dust-removing cavity 201, the mechanical performance requirements of the dust-removing cavity 201 are high. In addition, as the cylindrical electrode 204 of the triboelectric-heating electric-dust-removal detection device 1 of the embodiment of the invention is arranged on the inner surface of the annular side wall of the dust-removal cavity 201, in order to avoid short circuit, the dust-removal cavity 201 is made of an insulating material.
Referring to fig. 1 to 4, in some embodiments, the cylindrical electrodes 204 are disposed at intervals inside the dust-removing chamber 201.
The cylindrical electrodes 204 are cylindrical and arranged inside the dust removing cavity 201, and two adjacent cylindrical electrodes 204 are arranged at intervals. The cylindrical electrode 204 is positively charged by electrostatic induction. The waste particles 205 are negatively charged by friction with the media particles 206 and the media particles 206 are positively charged by friction with the waste particles 205. The cylindrical rotating shaft 103 drives the dust-removing cavity 201 to rotate, and the waste particles 205 and the medium particles 206 in the dust-removing cavity 201 also move continuously.
Under the electrostatic action generated by the friction, the negatively charged waste particles 205 migrate toward the cylindrical electrode 204, while the positively charged media particles 206 follow the rotation of the dedusting chamber 201. During the migration of the negatively charged waste particles 205 toward the cylindrical electrode 204 at a certain velocity, the negatively charged waste particles 205 are deflected by the action of the electric force and the gravity force (shown in fig. 4). The deflected waste particles 205 continue to migrate toward the cylindrical electrode 204 until they are adsorbed on the cylindrical electrode 204. Therefore, the deflected waste particles 205 can be more uniformly adsorbed on the cylindrical electrode 204, so that the phenomenon that a large amount of waste particles 205 are intensively adsorbed at a certain position of the cylindrical electrode 204 to influence the subsequent adsorption process is avoided, and the adsorption efficiency is improved. So, realize waste particles 205's collection in the waste gas under electrostatic absorption and physisorption's dual function to can carry out high-efficient quick filtration to the micro-nano-scale particulate matter through in the electric field.
In addition, the temperature inside the dust removing chamber 201 is increased by the above-mentioned friction. The exhaust gas flow 207 itself also carries heat. Therefore, a temperature difference Δ T exists between the outer surface of the annular sidewall of the dust-removing cavity 201 and the annular heat sink 300.
The material of the metal beam 203 and the cylindrical electrode 204 may be metal, such as gold (Au), lead (Pd), platinum (Pt), aluminum (Al), nickel (Ni), or titanium (Ti), or may be carbon (C). The dielectric particles 206 are insulators. The dielectric particles 206 are Polytetrafluoroethylene (PTFE) or Fluorinated ethylene propylene copolymer (FEP) having an electronegativity higher than that of the electrode material, or are quartz, glass, or silicate materials having an electronegativity lower than that of the electrode material. The high voltage electric field created by triboelectricity can directly electrostatically attract and physically attract the waste particles 205 with smaller diameters.
Referring to fig. 1, 2 and 3, the thermoelectric converter 30 is disposed around the outer surface of the annular sidewall of the dust-removing chamber 201. The thermoelectric converter 30 includes a thermoelectric device 301 and an annular heat sink 300. In the direction from the annular heat sink 300 to the outer surface of the annular sidewall of the dust-removing cavity 201, a first heat-conducting substrate 302, a first electrode layer 303, a p-type thermoelectric leg 304, an n-type thermoelectric leg 305, a second electrode layer 306 and a second heat-conducting substrate 307 are sequentially disposed.
Specifically, the waste particles 205 are triboelectrically charged with the media particles 206 and raise the temperature inside the dust extraction chamber 201. And the incoming airflow 202 may also carry heat and conduct to the second thermally conductive substrate 307. The second heat conducting substrate 307 is in contact with the outer surface of the annular sidewall of the dust-removing chamber 201, and heat is conducted from the inner surface of the annular sidewall of the dust-removing chamber 201 to the outer surface of the annular sidewall, the second heat conducting substrate 307, the second electrode layer 306, the n-type thermoelectric leg 305 and/or the p-type thermoelectric leg 304, the first electrode layer 303 and the first heat conducting substrate 302 in sequence. At this time, it corresponds to inputting a heat source to the second heat conductive substrate 307. The temperature of the second heat conductive substrate 307 at this time is T + Δ T. And the first heat conducting substrate 302 is in contact with the annular heat radiator 300, and the annular heat radiator 300 diffuses heat into the air around the triboelectric heating electric dust removal detection equipment 1. The temperature of the first thermally conductive substrate 302 at this time is T. Accordingly, there is a temperature difference Δ T between the first heat conducting substrate 302 and the second heat conducting substrate 307, and thus, holes in the p-type thermoelectric legs 304 migrate from the second heat conducting substrate 307 to the first heat conducting substrate 302, and electrons in the n-type thermoelectric legs 305 migrate from the second heat conducting substrate 307 to the first heat conducting substrate 302 (shown in fig. 5). In the loop of the first heat conducting substrate 302, the first electrode layer 303, the p-type thermoelectric leg 304, the n-type thermoelectric leg 305, the second electrode layer 306 and the second heat conducting substrate 307, a potential difference is generated between the p-type thermoelectric leg 304 and the n-type thermoelectric leg 305, so that current is generated in the loop. In other words, the thermoelectric device 301 recovers the thermal energy of the exhaust gas by converting the temperature difference Δ T between the outer surface of the annular sidewall of the dust removing chamber 201 and the annular radiator 300 into electric energy. Therefore, the friction electric heating electric dust removal detection equipment 1 of the embodiment of the invention saves energy and is more environment-friendly while effectively performing dust removal detection.

The first electrode layer 303, the second electrode layer 306, the metal beam 203, and the cylindrical electrode 204 may be made of the same material, and may be made of a metal such as gold (Au), lead (Pd), platinum (Pt), aluminum (Al), nickel (Ni), or titanium (Ti), or may be made of carbon (C).
