S. P. M. (Suspended particulate matter)
In order to reduce the amount of NOx (nitrogen oxides) by installing a filter in the exhaust circuit, research has been conducted on improving the combustion function of the engine. [0003] The black smoke emitted by diesel vehicles, S.M. P. M. However, the adverse effect of NOx on the human body has become a social problem, and reducing its emission has been an issue. However, the driving conditions of automobile engines are constantly changing from low speed to high speed and from low load to high load. The amount of harmful emissions will increase or decrease accordingly. Therefore, correspondingly black smoke, S.M. P. M. The challenge is to create an exhaust gas purification device that can collect and incinerate wastewater and reduce NOx emissions. [0004] In a copying machine, a toner is electrostatically charged with a toner, and the toner is adsorbed on a copy paper to be identified and charged with the opposite charge by a light beam. This is well known; P. M. Is also easily adsorbed by the same carbon-based material. Therefore, by applying the action of an electrostatic precipitator using electrostatic force, extremely fine S.D. P. M. Enabled collection. The collected S. P. M. H. Applying the electromagnetic induction heating effect known in the cooking appliance, the combustion promotion effect of the catalyst installed in advance, the high temperature of the exhaust gas itself, and the I.I. H. The incineration treatment is achieved by the heating action of. Regarding NOx, P.O. M. And NOx have a conflicting relationship. M. If the air-fuel ratio is optimized and the combustion effect is enhanced to reduce the generation of NOx, the combustion temperature rises and the generation of NOx increases. If the amount of NOx is reduced by a method such as lowering the combustion temperature,
P. M. The occurrence of increases. This means that the amount of oxygen in the exhaust gas is M. Is large, the amount of oxygen is large, and conversely, if the amount of NOx is large, the amount of oxygen is small. By utilizing this phenomenon, S.M. P. M. With the incineration of
Perform NOx reduction. In this device, air (oxygen) from other sources is not replenished.
S. P. M. Incineration process. S. P. M. Is mostly carbon, and is combined with oxygen by incineration to form carbon dioxide, thereby achieving emission and combustion. When NOx is generated, the amount of oxygen in the exhaust gas is rare, and P.O. Insufficient oxygen for combustion (oxidation) of M, HC (unburned hydrocarbons) and the like. Therefore, by the above-mentioned heating and the action of the catalyst, oxygen in NOx can be reduced, discharged as nitrogen and carbon dioxide, and NOx can be reduced. By the above means, S.S. P. M. Collection, incineration and NOx reduction. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cylindrical purifier main body (1) is connected to an exhaust pipe of a muffler of an engine, an exhaust gas flow alleviation plate (2) is installed above the inside of the main body, and S is disposed near a center. . P.
M. The electrode rod (3) for charging the (suspended particulate matter) with an electrostatic charge is oppositely charged by the insulator (4) and the stay (5) with respect to the device and the electrode rod.
P. M. Of iron or stainless steel suitable for electromagnetic heating for sucking air and having a number of cylindrical holes perforated for ventilation. P. M. The collection cylinder (6) is installed. Inside the collection cylinder, a metal mesh or metal woven fabric made of S.I. P. M. A required number of adsorbent materials (7) and platinum, nickel and rhodium-like catalyst materials (8), which are also in the form of wire mesh, are alternately interposed between the adsorbent materials and the catalyst materials. Install at the bottom. Below the bottom of the collection cylinder, I.P. H. (Electromagnetic induction) The electromagnetic coil (10) of the heating device is installed outside the main body via the ceramic plate (9), and the electric cooling fan (11) is installed below the electromagnetic coil. Separately, a power generator (1
2) A structure in which a power supply device (13) and an exhaust pipe (14) are provided. The operation of the present invention will be described with reference to an embodiment. As shown in FIG. 1, the exhaust gas from the silencer flows into the main body, the flow of the exhaust gas is alleviated by the relaxation plate, and the electrode rod is formed. Reach the periphery. A high-voltage current is supplied to the electrode rod by a separately provided high-voltage supply device. P. M. Charges an electric charge. The opposite collecting cylinder and the adsorbing material are charged with opposite charges as cylindrical electrodes. P. M. Is adsorbed on the adsorbing material by electrostatic force, and the exhaust gas is purified and discharged. S. collected and adsorbed P. M. To explain the combustion process, when power is supplied from a separately installed power supply to the electromagnetic coil of the electromagnetic induction heater installed below the collection tube, the electromagnetic coil generates magnetic force lines and passes through the ceramic plate. Then, the lines of magnetic force reach the collection tube and the adsorption material. The collection tube and the adsorbing material generate an eddy current due to the lines of magnetic force, and themselves become a heating element and generate heat. The S.A. collected by the electrostatic dust collection action described above. P. M. Is easily combined with oxygen in the exhaust gas to form carbon dioxide by the heat generation of the collecting cylinder, the high temperature of the exhaust gas itself, and the combustion promoting action of the catalyst interposed in the adsorbing material, and the combustion treatment is achieved. Regarding NOx reduction,
As described in the above section, when NOx is generated, the amount of oxygen in the exhaust gas is scarce. P. M. Lack of oxygen for incineration, heating by electromagnetic heating, P. M. Oxygen in NOx is reduced and released as nitrogen and carbon dioxide by the heat generated by incineration and the chemical promoting action of the catalyst.
Ox emission can be reduced. The insulator stay of the electrode rod is made of a vibrating metal, so that the acoustic wave vibration of the exhaust gas itself causes a gradient force (a phenomenon that particles are deposited on the electrode rod) on the electrode rod.
P. M. It is possible to prevent accumulation. In this embodiment, a small AC generator (12) driven by an attached engine is installed as a power source for an electromagnetic heating device for supplying a high voltage for electric dust collection, and power is controlled by a power supply device (13). And supply it to the device. An electric cooling fan (11) is mounted below the heating electromagnetic coil to prevent the coil from becoming hot and the magnetic field lines from attenuating due to the high temperature. According to the present invention, the function of the electric dust collecting device is as follows.
S. P. M. It is applied to collection, has high dust collection performance, can collect extremely fine particles, can be used even under high pressure and high temperature, and can be used in high temperature exhaust gas. P. M. It is suitable for collecting and achieves a sufficient effect. The collected S. P. M. In the method, the collection tube and the adsorbing material itself become a heating element, and the incineration action is always performed continuously by the heat generation and the combustion promoting action of the catalyst. Therefore, there is no fear of clogging of the adsorbing material. Regarding the power used, while a high voltage is used for the static electrode, the current (corona current) is extremely small. H. The heating device also has the high temperature of the exhaust gas itself,
S. P. M. Due to the heat generated during incineration and the use of catalysts,
An excessively large amount of heat is not required, and therefore, the power supply is small and the use of a small generator is sufficient, so that the engine load loss is small. This device uses S.T. P. M. Both effects of incineration and NOx reduction can be easily achieved.
