Therefore, it is usually necessary to use some devices to deal with the oil fume mixture problem.
[0003] The existing method for treating the oil fume mixture mainly uses a heating wire to directly heat and decompose the oil fume mixture at high temperature, but this method has high power and the risk of overheating. Utility Model Content

The oil fume mixture filtered by the filter layer can be further purified by a catalyst.
[0005] In order to achieve the above object, the embodiment of the utility model adopts the following technical solution:
[0006] The embodiment of the utility model provides an electromagnetic high-temperature moxibustion oil fume catalytic reaction device, including a shell, a catalytic chamber, a filter layer and an electromagnetic heating coil.

The catalytic chamber is arranged in the combustion chamber, and a reaction chamber is formed inside the catalytic chamber, and a catalyst is installed in the reaction chamber; the catalytic chamber has a second smoke outlet connected to the first smoke outlet.

A heating lamp with a higher power should be equipped with a farther lamp distance to avoid the danger of overheating. The present application adopts electromagnetic heating, which is contactless and safe.
[0028] like Figure 1 As shown, an embodiment of the utility model provides an electromagnetic high-temperature moxibustion oil fume catalytic reaction device 2, comprising a shell 1, a catalytic chamber 2, a filter layer 3 and an electromagnetic heating coil 4. Among them, a combustion chamber 11 and a first smoke inlet 111 and a first smoke outlet 112 connected to the combustion chamber 11 are formed inside the shell 1. The catalytic chamber 2 is arranged in the combustion chamber 11, and a reaction chamber 21 is formed inside the catalytic chamber 2, and a catalyst 6 is installed in the reaction chamber 21; the catalytic chamber 2 has a second smoke outlet 212 connected to the first smoke outlet 112. There is an interlayer 5 between the catalytic chamber 2 and the shell 1, and the filter layer 3 is installed at the interlayer 5; the catalytic chamber 2 has a second smoke inlet 211 connected to the interlayer 5. The electromagnetic heating coil 4 is sleeved on the outside of the shell 1 for heating the combustion chamber 11.
[0029] In this case, the particulate matter in the oil fume mixture can be intercepted by the filter layer 3, and the intercepted particulate matter can be burned by electromagnetic heating. The oil fume mixture filtered by the filter layer can be further purified by the catalyst 6.
[0030] Among them, the catalyst can be a precious metal catalyst, which plays a key role in the field of flue gas treatment. It is mainly used to catalyze and oxidize harmful substances in flue gas, such as carbon monoxide (CO), volatile organic compounds (VOCs) and other toxic gases, to reduce air pollution and meet strict environmental emission standards. These catalysts mainly contain precious metals such as platinum (Pt), palladium (Pd), and rhodium (Rh) as active ingredients. They have excellent catalytic properties, including high catalytic activity, selectivity and thermal stability. The catalyst 6 is installed in a special catalytic chamber 2.
[0031] The structure of the catalytic chamber 2 is specifically described below. For example, in some embodiments of the present application, Figure 1 and Figure 2 As shown, the catalytic chamber 2 is cylindrical, and one side of the catalytic chamber 2 having a second smoke inlet 211 abuts against the inner wall of the combustion chamber 11, and a plurality of second smoke inlets 211 are provided at the abutment of the catalytic chamber 2. In this case, the oil smoke mixture can enter the catalytic chamber 2 through the second smoke inlet 211 at the bottom after passing through the filter layer 3. Specifically, Figure 2 As shown, the second smoke inlet 211 can be opened at intervals at the bottom of the catalytic chamber 2.
[0032] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the electromagnetic high-temperature moxibustion oil fume catalytic reaction device 2 further includes a fan 7 and a motor 8, wherein the fan 7 is installed in the reaction chamber 21 and is located between the second smoke inlet 211 and the catalyst 6. The motor 8 is connected to the fan 7 and is used to drive the fan 7 to rotate, so that the airflow at the second smoke inlet 211 is introduced into the second smoke outlet 212 through the fan 7.
[0033] In this case, the fan 7 can provide kinetic energy for the oil fume mixture entering the electromagnetic high-temperature moxibustion oil fume catalytic reaction device 2, so that it can circulate quickly. The motor 8 provides electric energy for the fan 7 to ensure that the fan 7 can operate normally.
[0034] like Figure 3 As shown, the electromagnetic high-temperature moxibustion oil fume catalytic reaction device 2 also includes a bearing 9, the outer ring of the bearing 9 is fixed on the side wall of the reaction chamber 21, the motor 8 is located outside the housing 1, and the motor 8 has a rotating shaft 81, the rotating shaft 81 passes through the inner ring of the bearing 9 and is connected to the fan 7, and the inner ring of the bearing 9 is connected to the rotating shaft 81. In this case, the bearing 9 can enable the rotating shaft 81 of the motor 8 to be movably connected to the housing 1, thereby ensuring the connection stability between the motor 8 and the fan 7.
[0035] In some embodiments of the present application, Figure 3 As shown, the electromagnetic high temperature moxibustion oil fume catalytic reaction device 2 also includes a fin tube 10, one end of which is connected to the second smoke outlet 212, and the other end is connected to the first smoke outlet 112. The fin tube 10 can transfer the heat of the gas flowing in the tube to the oil fume mixture in the combustion chamber 11 to perform heat transfer, thereby saving electric energy.
[0036] In some embodiments of the present application, the electromagnetic high-temperature moxibustion oil fume catalytic reaction device 2 also includes a thermal expansion layer 21, which is arranged between the reaction chamber 21 and the catalyst 6, and is used to fix the catalyst 6 by heating. The thermal expansion layer 21 can be a thermal expansion sealant, a thermal expansion caulking material, a thermal expansion fireproof material, etc., which has a specific thermal expansion property and can change in volume or shape after being heated, and is used to achieve fastening, sealing or connecting functions within a certain temperature range. It can be an expansion cotton, which is not limited in the present application.
[0037] In some embodiments of the present application, the electromagnetic high-temperature moxibustion oil fume catalytic reaction device 2 further includes a thermal insulation layer 23, which is at least wrapped around the electromagnetic heating coil 4 on the outside of the housing 1 for thermal insulation. The material of the thermal insulation layer 23 can be selected from one or more of rock wool board, glass wool, phenolic foam board, polyurethane thermal insulation material, vitrified micro-bead thermal insulation mortar and foam glass, and the present application does not limit the material of the thermal insulation layer 23.
[0038] The filter layer 33 in the above embodiment is described below by way of example. For example, the filter layer 33 is one or more of a metal mesh filter layer, a honeycomb filter layer and a nanofiber filter layer.
[0039] In some embodiments of the present application, an electromagnetic heating controller may also be included: the electromagnetic heating controller is a device that uses the principle of electromagnetic heating to convert electrical energy into thermal energy. The electromagnetic heating controller rectifies 220V, 50 / 60HZ AC power into DC power, and then converts the DC power into high-frequency, high-voltage power with a frequency of 20-40KHZ, or converts 380v 50 / 60HZ three-phase AC power into DC power and then converts the DC power into 10~30KHZ high-frequency, low-voltage, and high-current power.
[0040] High-frequency and high-voltage current flowing through the electromagnetic heating coil 4 will generate a high-speed alternating magnetic field. When the iron-containing container catalytic chamber 2 is placed inside, the surface of the container cuts the alternating magnetic field lines and generates alternating current (i.e. eddy current) in the metal part inside the container. The eddy current makes the carriers inside the container move irregularly at high speed, and the carriers collide and rub against each other to generate heat energy, thereby achieving a heating effect.
[0041] In summary, in this application, the first stage is: the smoke gas enters and exchanges heat with the purified gas, and circulates back and forth. The second stage is: electromagnetic heating simultaneously makes the internal pipe diameter and the internal filter stainless steel wire mesh filter reach a high temperature state of about 500 degrees, thereby increasing the adsorption and combustion time, making it more sufficient and the effect better. The third stage is: the long-axis motor fan sends the burned gas of the oil smoke into the catalytic bin for catalytic decomposition.
[0042] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
