In this way, the collection of waste particles 205 in the exhaust gas is realized under the dual effects of electrostatic adsorption and physical adsorption, and the dust removal effect is good. At the same time, the temperature difference between the outer surface of the annular side wall of the dust removal chamber 201 and the annular radiator 300 is converted into electric energy through the thermoelectric device 301, and the heat energy of the exhaust gas is recycled, thereby providing the electric motor 207, the air intake detector 105 and the exhaust air. The detector 107 is powered, which saves energy and is more environmentally friendly. In addition, by setting the intake detector 105 and the exhaust detector 107 at the intake pipe 101 and the exhaust pipe 108 of the dust removal chamber 201, the adsorption of the waste particles 205 and the real-time detection are carried out simultaneously without causing secondary Pollution, thereby achieving a high standard of discharge.

Specifically, the intake air flow 202 enters the interior of the dust removal chamber 201 from the intake pipe 101 and diffuses in the interior of the dust removal chamber 201 . The waste particles 205 contained in the intake airflow 202 rub against the medium particles 206 in the dust removal chamber 201 , and/or the waste particles 205 rub against the cylindrical electrode 204 in the dust removal chamber 201 , so that the waste particles 205 are charged. Due to friction, a high voltage electric field is formed inside the dust removal cavity 201 . At this time, the temperature inside the dust removal chamber 201 rises. Intake airflow 202 may also carry heat itself. Therefore, there is a temperature difference between the outer surface of the annular side wall of the dust removal cavity 201 and the annular radiator 300 . The thermoelectric converter 30 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 electrical energy through the thermoelectric device 301, thereby supplying power to the electric motor 207, the intake detector 105 and the exhaust detector 107 , recycling the heat energy of the exhaust gas.

Under the action of the high-voltage electric field, the waste particles 205 are deeply ionized into charged ions and are adsorbed by the cylindrical electrode 204 inside the dust removal chamber 201 . Due to the different mass of the waste particles 205, the charged amount is different. The triboelectric thermoelectric internal stirring dust removal detection device 1 of the embodiment of the present invention uses a DC/DC boost module to manage the electrical output of the thermoelectric device 301 to better match the voltage input requirements of the electric motor 207 and increase the stirring of the internal stirring rope 208 The speed makes the waste particles 205 and medium particles 206 with different charges deflect and fully friction to achieve deep ionization, and at the same time increase the electrostatic induction voltage of the cylindrical electrode 204 . In this way, the waste particles 205 with different charges can still be adsorbed on the cylindrical electrode 204 under the action of the high-voltage electric field, realizing effective adsorption of the waste particles 205 .

In addition, the triboelectric pyroelectric internal stirring and dust removal detection device 1 further includes an electric motor trigger device 109 , and the electric motor trigger device 109 is electrically connected to the electric motor 207 . The intake detector 105 detects the composition parameters of the intake gas flow 202 , and the exhaust gas detector 107 detects the composition parameters of the exhaust gas flow 209 . By comparing the composition parameter of the intake airflow 202 with the composition parameter of the exhaust airflow 209 , and feeding back to the electric motor trigger device 109 . If the component parameters of the exhaust gas flow 209 have not yet reached the standard, the electric motor trigger device 109 triggers the electric motor 207 to continue to drive the inner stirring rope 208 to carry out random stirring until the component of the exhaust gas flow 209 reaches the discharge standard, and then the exhaust Air flow 209 is exhausted, thereby achieving pollution-free discharge.

Wherein, the type of the intake detection probe 104 is the same as that of the exhaust detection probe 106 . The intake detection probe 104 and the exhaust detection probe 106 may be one or more of a temperature and humidity detector, a chemical component analysis detector, and a micro-nano particle size detector. The intake detection probe 104 and the exhaust detection probe 106 can be used to detect one or more of temperature and humidity, chemical composition, and particle size.

Please refer to FIG. 1 again. In some embodiments, the dust removal device includes a fan-shaped cylindrical filter screen 102 disposed downstream of the air intake duct 101 . The fan-shaped cylindrical filter screen 102 is arranged in the dust removal cavity 201 .

The dust removal equipment is cylindrical, and the air intake pipe 101 is also cylindrical. One end of the air intake pipe 101 is arranged outside the dust removal cavity 201 , and the other end is connected with the upper bottom of the fan-shaped cylindrical filter screen 102 . The lower bottom of the fan-shaped cylindrical filter screen 102 faces the inside of the dust removal cavity 201 . The diameter of the upper base is smaller than the diameter of the lower base. In this way, when the intake airflow 202 enters the dust removal chamber 201 along the intake pipe 101, on the one hand, the waste particles 205 with larger diameters are filtered by the fan-shaped cylindrical filter screen 102 and do not enter the dust removal chamber 201, which reduces the The amount of waste particles 205 entering the interior of the dust removal chamber 201 . On the other hand, the waste particles 205 with smaller diameter are guided by the fan-shaped cylindrical filter screen 102, and the intake airflow 202 is more likely to diffuse in the dust removal chamber 201, so that the waste particles 205 with a smaller diameter and the media particles 206 are evenly mixed .

Wherein, the materials of the air intake pipe 101, the fan-shaped cylinder filter screen 102, the fixing bracket 103, and the exhaust pipe 108 can be the same, and can be made of stainless steel (such as 304 stainless steel) or metal copper respectively.

The dust removal cavity 201 is made of insulating material with high mechanical performance, such as insulating polymer material, insulating bakelite, or insulating ceramic. Since waste particles 205 and medium particles 206 rotate at high speed inside the dust removal chamber 201 , the mechanical performance requirements of the dust removal chamber 201 are high. In addition, since the interior of the dust removal chamber 201 of the triboelectric pyroelectric internal stirring dust removal detection device 1 according to the embodiment of the present invention is provided with a cylindrical electrode 204, in order to avoid a short circuit inside and outside of the dust removal chamber 201, the dust removal chamber 201 is insulated. Material.

Please refer to FIG. 1 to FIG. 4 together, the cylindrical electrodes 204 are arranged at intervals inside the dust removal cavity 201 .

The cylindrical electrodes 204 have a cylindrical shape and are arranged inside the dust removal chamber 201 , and two adjacent cylindrical electrodes 204 are arranged at intervals. The cylindrical electrode 204 is positively charged under electrostatic induction. Waste particles 205 are negatively charged by friction with media particles 206 , and/or waste particles 205 are negatively charged by friction with cylindrical electrode 204 , and media particles 206 are positively charged by friction with waste particles 205 . When electrified, the rotor on the electric motor 207 drives the inner stirring rope 208 to stir randomly in the dust removal chamber 201 . Through stirring, the waste particles 205 and the medium particles 206 inside the dust removal cavity 201 are mixed more evenly.

Under the action of static electricity generated by friction, the negatively charged waste particles 205 migrate toward the cylindrical electrode 204 , while the positively charged medium particles 206 follow the stirring of the inner stirring rope 208 to move. When the negatively charged waste particles 205 migrate toward the cylindrical electrode 204 at a certain speed, the negatively charged waste particles 205 accelerate toward the cylindrical electrode 204 under the agitation of the inner stirring rope 208 until they are adsorbed on the cylindrical electrode 204 . In this way, the waste particles 205 can be adsorbed on the cylindrical electrode 204 more uniformly and rapidly, preventing a large amount of waste particles 205 from being adsorbed at a certain position of the cylindrical electrode 204 and affecting the subsequent adsorption process, and improving the adsorption efficiency. The collection of the waste particles 205 in the exhaust gas is realized under the double action of electrostatic adsorption and physical adsorption, and it is possible to efficiently and quickly filter the micro-nano-scale particles passing through the electric field.

In addition, under the above-mentioned friction, the temperature inside the dust removal chamber 201 rises. The exhaust gas flow 209 itself also carries heat. Therefore, there is a temperature difference ΔT between the outer surface of the annular side wall of the dust removal cavity 201 and the annular radiator 300 .

Wherein, the material of metal beam 203 and cylindrical electrode 204 can be metal, such as gold (Au), lead (Pd), platinum (Pt), aluminum (Al), nickel (Ni), or titanium (Ti). is carbon (C). Dielectric particles 206 are insulators.

The high-voltage electric field formed by triboelectricity can directly electrostatically adsorb and physically adsorb waste particles 205 with smaller diameters. The electric motor 207 is a 12V electric motor, and may also be a 6V electric motor or a 9V electric motor.

The second heat-conducting base 307 is in contact with the outer surface of the annular side wall of the dust removal chamber 201, and the heat is sequentially conducted from the inner surface of the annular side wall of the dust removal chamber 201 to the outer surface of the annular side wall, the second heat-conducting base 307, and 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 . At this time, it is equivalent to inputting a heat source to the second heat conduction substrate 307 . At this time, the temperature of the second heat-conducting substrate 307 is T+ΔT. While the first heat-conducting base 302 is in contact with the annular radiator 300 , the annular radiator 300 diffuses heat into the surrounding air of the triboelectric thermoelectric internal stirring dust removal detection device 1 . At this moment, the temperature of the first heat-conducting substrate 302 is T. Therefore, there is a temperature difference ΔT between the first heat-conducting substrate 302 and the second heat-conducting substrate 307, therefore, the holes in the p-type thermoelectric leg 304 migrate from the second heat-conducting substrate 307 to the first heat-conducting substrate 302, and the holes in the n-type thermoelectric leg 305 The electrons migrate from the second heat-conducting substrate 307 to the first heat-conducting substrate 302 (shown in FIG. 5 ).

In other words, the thermoelectric device 301 recovers the heat energy of the exhaust gas by converting the temperature difference ΔT between the outer surface of the annular side wall of the dust removal chamber 201 and the annular radiator 300 into electrical energy.
