Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a novel treatment device for magnetic energy oxidation. Background Art

[0002] In China, VOCs (volatile organic compounds) refer to organic compounds with a saturated vapor pressure greater than 70.91 Pa at room temperature, a boiling point below 50~260°C at a standard atmospheric pressure of 101.3 kPa, and an initial distillation point equal to 250 degrees Celsius, or any organic solid or liquid that can evaporate at room temperature and pressure.

[0003] At present, VOCs (volatile organic compounds) waste gas treatment is an important part of air pollution control, and is of great significance for improving air quality and protecting people's health. In recent years, VOCs waste gas has been mainly treated by combustion method, including thermal oxidation and catalytic oxidation, which oxidizes VOCs into carbon dioxide and water at high temperature with high treatment efficiency. That is, heating is used to raise the temperature of VOCs waste gas to a certain degree so that the organic waste gas inside it undergoes thermal oxidation reaction or uses a catalyst to accelerate the oxidation of organic waste gas.

[0004] At present, the market mostly uses the heat storage combustion method to heat VOCs waste gas. There are also related reports that propose to heat VOCs waste gas by electromagnetic heating. Although the thermal efficiency of electromagnetic heating is very high, which can reach more than 90%, it can directly act on the induction coil of the heated object, reducing the intermediate transfer loss of heat. However, electromagnetic heating mainly relies on the direct heat generated by the high-frequency migration friction of electrons in the conductor. When heating a gas that contains almost no electrons, it can only rely on heat exchange for heating. Therefore, its high thermal energy efficiency cannot be applied to the heating of VOCs waste gas. In recent years, although electromagnetic heating has been proposed as a heating method for VOCs waste gas oxidation, its thermal utilization efficiency has not been effectively improved, so it is difficult to put into use. At this stage, the thermal oxidation treatment of VOCs waste gas has become mature, but because the temperature required for its thermal oxidation is generally as high as 800°C, it takes a lot of energy to heat the waste gas to the required temperature in a short time. There is no lack of heat storage and heat exchange methods in the existing technology to improve the thermal energy utilization rate, but the heating method and energy utilization rate still need to be improved and perfected.

[0005] In view of the above problems, it is urgently necessary to carry out innovative design based on the original VOCs waste gas heat treatment device. Summary of the invention

[0006] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a new treatment device for magnetic energy oxidation to solve the problem that the existing technologies proposed in the above background technology are not lacking in heat storage and heat exchange methods to improve the utilization rate of thermal energy, but the heating methods and energy utilization rates still need to be improved and perfected.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of magnetic oxidation treatment device, comprising an air intake pipe, wherein the air intake pipe is composed of a straight pipe at the air intake end and a preheated annular pipe, and the end of the annular pipe is connected to one end of a multi-stage bent pipe, and the other end of the multi-stage bent pipe is connected to the air intake end of an exhaust pipe, the middle section of the exhaust pipe is arranged as a bent arc pipe, and the connection between the arc pipe and the straight pipes at both ends is respectively provided with a first connecting pipe and a second connecting pipe.

[0008] Preferably, the first connecting pipe, the second connecting pipe, the annular pipe and the arc-shaped pipe of the exhaust pipe together form a concentric ring.

[0009] Preferably, an electromagnetic heating coil is wound around the outer wall of the arc tube, and both ends of the electromagnetic heating coil are electrically connected to an electromagnetic heating device.

[0010] Preferably, an electromagnetic induction ring limited by the first connecting tube and the second connecting tube is arranged at the center of the concentric rings, and an outer opening plate is arranged at equal angles on the outer side of the electromagnetic induction ring, and an inner opening plate is arranged at equal angles on the inner side of the electromagnetic induction ring, and an integrated self-rebound component is installed between the outer opening plate, the inner opening plate and the electromagnetic induction ring.

[0011] Preferably, the first connecting tube and the second connecting tube are both fitted with the annular outer wall of the electromagnetic induction ring, and the outer opening plate and the inner opening plate are arranged in an arc shape with a gradually changing thickness. When opened, the thicker end of the outer opening plate and the inner opening plate is away from the electromagnetic induction ring and the thinner end is close to the electromagnetic induction ring.

[0012] Preferably, the integrated self-rebounding assembly comprises a telescopic rod, a telescopic slot, a guide rod, a slider, a groove and a second spring, and the outer side and the inner side of the electromagnetic induction ring are provided with telescopic slots, one end of the telescopic rod is slidably arranged inside the telescopic slot, and the other end of the telescopic rod is hinged with a slider, and a guide rod is arranged inside the slider, and the guide rod is fixedly mounted on the opposite surfaces of the outer opening plate and the inner opening plate and the electromagnetic induction ring, and the ends of the two sliders are respectively fitted with the inner surfaces of the outer opening plate and the inner opening plate; The outer side and the inner side of the electromagnetic induction ring are both provided with grooves, and one end of a second spring is welded inside the groove, and the other ends of the two second springs are respectively fixed to the inner surfaces of the outer opening plate and the inner opening plate.

[0013] Preferably, the inner and outer sides of the electromagnetic induction ring are provided with surface grooves that exactly match the outer opening plate and the inner opening plate, and the outer surfaces of the outer opening plate and the inner opening plate are spliced ​​with the inner and outer sides of the electromagnetic induction ring to form a complete annular surface.

[0014] Preferably, a first spring is wound around the outer wall of the telescopic rod located inside the telescopic slot, one end of the first spring is welded to the end of the telescopic rod, and the other end of the first spring is fixed to the inner wall of the telescopic slot.

[0015] Preferably, the first spring and the second spring are both made of high temperature resistant elastic materials, and the outer opening plate and the inner opening plate are both made of high temperature resistant metal materials.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When the VOCs exhaust gas from the annular tube of the intake pipe contacts the outer and inner plates which are equally distributed on the inner and outer walls of the electromagnetic induction ring, since the outer and inner plates are both wind-blocking arrangements, under the fluid action of the VOCs exhaust gas, the wind resistances of the multiple sets of outer and inner plates will be superimposed until the electromagnetic induction ring is driven to rotate counterclockwise at a variable speed in the concentric rings composed of the first connecting tube, the second connecting tube, the annular tube and the arc tube, wherein the first connecting tube and the second connecting tube are mainly used to ensure the annular rotation of the electromagnetic induction ring and to avoid direct connection between the annular tube and the arc tube, and when the outer and inner plates rotate counterclockwise with the electromagnetic induction ring to the pipe mouth of the first connecting tube, they are restricted by the diameter of the first connecting tube, and the outer and inner plates will gradually match and snap into the inside of the electromagnetic induction ring in the order of entering the tube, so that they form a short-term integrated state with the electromagnetic induction ring, and when the outer and inner plates enter the exhaust pipe through the first connecting tube The first spring and the second spring rebound and reset synchronously to lift up the corresponding outer opening plate and inner opening plate again, so that the outer opening plate and inner opening plate located in the exhaust pipe are in an open state again, and the outer opening plate and inner opening plate rotating clockwise at a certain angle inside the exhaust pipe have a relatively stable "wind-breaking" effect, which can break the VOCs exhaust gas transmitted from right to left in the exhaust pipe, forming gas turbulence, so that the exhaust gas that originally had insufficient heat exchange can contact the heat source evenly and directly, ensuring that the heat transfer is faster and more direct, and the electromagnetic induction ring, the outer opening plate and the inner opening plate will also heat up synchronously under electromagnetic induction, so that the electromagnetic heating device, under the same heating power, not only has the skin heating of the inner wall of the exhaust pipe, but also has the surface heating of the electromagnetic induction ring, the outer opening plate and the inner opening plate at the center of the exhaust pipe, which diffuses the distribution of the heat source and exists in a dynamic form. The superposition of multiple effects further improves the heat conversion rate and heat exchange rate of the electromagnetic heating exhaust gas.

[0017] Finally, the electromagnetic induction ring in the middle arc section of the exhaust pipe will carry the outer opening plate and the inner opening plate that have been electromagnetically heated and retract to the surface of the electromagnetic induction ring and pass through the second connecting pipe. Similarly, after entering the annular tube of the intake pipe, the outer opening plate and the inner opening plate are opened again. At this time, the opened outer opening plate and the inner opening plate and the corresponding electromagnetic induction ring carry a certain amount of electromagnetic waste heat, which can have a stable preheating effect on the VOCs exhaust gas that has just entered the annular tube. After stable operation of the equipment, the preheating temperature can be as high as %-% of the required temperature, which once again improves the utilization rate of electromagnetic heat, so as to achieve the effect of rapid heating of the VOCs exhaust gas in a short time. According to the above-mentioned implementation steps and principles, the VOCs exhaust gas after stable heating can be obtained by cycling. The subsequent exhaust pipe can be connected to the (catalytic) oxidation chamber based on the existing technology to carry out a series of reactions and treatments. This article and the accompanying drawings do not make too much additional explanation.

[0018] To sum up: when the VOCs waste gas enters the interior of the intake pipe, it will first be preheated by the electromagnetic induction ring, the outer opening plate and the inner opening plate. At the same time, the wind speed difference caused by the diameter difference between the straight pipe and the annular pipe of the intake pipe and the curvature difference between the annular pipe and the arc pipe are used to cause the electromagnetic induction ring to rotate without power output, and the speed of rotation is determined based on the flow rate of VOCs waste gas per unit time. Then, the heated electromagnetic induction ring will reversely enter the arc pipe of the exhaust pipe and stably receive electromagnetic heating. The "wind-breaking" property of the outer opening plate and the inner opening plate is cleverly used to form turbulence in the exhaust pipe to promote the contact and heat exchange between the gas and the heat source. The electromagnetic induction ring, the outer opening plate and the inner opening plate themselves will also undergo electromagnetic induction to form a new central heat source, which diffuses the distribution of the heat source and exists in a dynamic form. The superposition of multiple effects further improves the heat conversion rate and heat exchange rate of the electromagnetic heated exhaust gas. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The first connecting tube 11 and the second connecting tube 12 are both fitted with the annular outer wall of the electromagnetic induction ring 5, and the outer opening plate 6 and the inner opening plate 7 are arc-shaped with gradually changing thickness. When opened, the thicker end of the outer opening plate 6 and the inner opening plate 7 is away from the electromagnetic induction ring 5 and the thinner end is close to the electromagnetic induction ring 5.

[0027] The integrated self-rebound component includes a telescopic rod 8, a telescopic groove 81, a guide rod 83, a slider 84, a groove 85 and a second spring 86, and the telescopic groove 81 is provided on the outer side and the inner side of the electromagnetic induction ring 5, one end of the telescopic rod 8 is slidably provided inside the telescopic groove 81, and the other end of the telescopic rod 8 is hinged with a slider 84, and a guide rod 83 is provided inside the slider 84, and the guide rod 83 is fixedly installed on the opposite surfaces of the outer opening plate 6 and the inner opening plate 7 and the electromagnetic induction ring 5, and the ends of the two sliders 84 are respectively in contact with the inner surfaces of the outer opening plate 6 and the inner opening plate 7; Grooves 85 are provided on the outer side and the inner side of the electromagnetic induction ring 5 , and one end of a second spring 86 is welded inside the groove 85 , and the other ends of the two second springs 86 are fixed to the inner surfaces of the outer opening plate 6 and the inner opening plate 7 respectively.

[0028] The inner and outer sides of the electromagnetic induction ring 5 are provided with surface grooves that exactly match the outer opening plate 6 and the inner opening plate 7, and the outer surfaces of the outer opening plate 6 and the inner opening plate 7 are spliced ​​with the inner and outer sides of the electromagnetic induction ring 5 to form a complete annular surface.

[0029] A first spring 82 is wound around the outer wall of the telescopic rod 8 inside the telescopic slot 81 , one end of the first spring 82 is welded to the end of the telescopic rod 8 , and the other end of the first spring 82 is fixed to the inner wall of the telescopic slot 81 .

[0030] The first spring 82 and the second spring 86 are both made of high temperature resistant elastic materials, and the outer opening plate 6 and the inner opening plate 7 are both made of high temperature resistant metal materials. Embodiment: When using the novel treatment device of magnetic energy oxidation, first Figure 1 As shown in FIG. 1 , VOCs waste gas is introduced from the straight pipe end of the air inlet pipe 1. As can be seen from the figure, there is a difference in diameter between the straight pipe and the curved pipe of the air inlet pipe 1. The gas transmission speed of the VOCs waste gas entering from the straight pipe with a larger diameter will be increased accordingly after entering the curved pipe with a relatively smaller diameter. Figure 3 and Figure 4 As shown, the VOCs waste gas entering the bend pipe will eventually be introduced into the exhaust pipe 2 through the multi-stage bend pipe 4 connected to the lower end of the bend pipe, and the waste gas inside the exhaust pipe 2 will be stably transmitted from right to left.

[0031] After the intake air is stabilized, the electromagnetic heating device 3 is started. The electromagnetic heating device 3 directly transfers heat to the inner wall of the arc-shaped tube through the electromagnetic heating coil wound around the arc-shaped tube in the middle section of the exhaust pipe 2 (this involves a phenomenon of electromagnetic induction: the skin effect, which means that in an AC circuit, the current is unevenly distributed on the surface of the conductor. As the frequency increases, the current tends to flow near the surface of the conductor instead of being evenly distributed over the entire cross-section of the conductor. When electromagnetically heating a metal pipe, the heat does not directly heat the gas, but gathers on the inner wall of the pipe under the skin effect. The gas inside the pipe is mainly heated by heat exchange with the inner wall of the pipe). At the same time, Figure 1 As shown, the electromagnetic induction ring 5 is located at the center of the arc tube. Therefore, based on the principle of skin effect, the surface of the electromagnetic induction ring 5 will also be synchronously affected by the electromagnetic field to generate heat.

[0032] Based on the above analysis, when the VOCs waste gas accelerated into the annular tube of the intake pipe 1 contacts the outer opening plates 6 and the inner opening plates 7 distributed at equal angles on the inner and outer walls of the electromagnetic induction ring 5, since the outer opening plates 6 and the inner opening plates 7 are both wind-blocking arrangements, under the fluid action of the VOCs waste gas, the wind resistances of the multiple sets of outer opening plates 6 and the inner opening plates 7 will be superimposed until the electromagnetic induction ring 5 is driven to rotate counterclockwise at a variable speed in the concentric rings composed of the first connecting tube 11, the second connecting tube 12, the annular tube and the arc tube, wherein the first connecting tube 11 and the second connecting tube 12 are connected to each other. The connecting pipe 12 is mainly used to ensure the annular rotation of the electromagnetic induction ring 5 and to avoid direct connection between the annular pipe and the arc pipe. When the outer opening plate 6 and the inner opening plate 7 rotate counterclockwise with the electromagnetic induction ring 5 to the pipe mouth of the first connecting pipe 11, the outer opening plate 6 and the inner opening plate 7 will gradually match and snap into the inside of the electromagnetic induction ring 5 in the order of entering the pipe, so that they form a short-term integrated state with the electromagnetic induction ring 5. When the outer opening plate 6 and the inner opening plate 7 enter the exhaust pipe 2 through the first connecting pipe 11, as shown in FIG. Figure 6 , Figure 7 and Figure 8As shown, the first spring 82 and the second spring 86 rebound and reset synchronously to lift up the corresponding outer opening plate 6 and inner opening plate 7 again, so that the outer opening plate 6 and the inner opening plate 7 located in the exhaust pipe 2 are in an open state again, and the outer opening plate 6 and the inner opening plate 7 rotating clockwise at a certain angle inside the exhaust pipe 2 have a relatively stable "wind-breaking" effect, which can break the VOCs exhaust gas transmitted from right to left in the exhaust pipe 2, forming gas turbulence, so that the exhaust gas that originally had insufficient and uneven heat exchange can contact the heat source evenly and directly, ensuring that the heat transfer is faster and more direct, and the electromagnetic induction ring 5, the outer opening plate 6 and the inner opening plate 7 will also heat up synchronously under electromagnetic induction, so that the electromagnetic heating device 3, under the same heating power, not only has the skin heating of the inner wall of the exhaust pipe 2, but also has the surface heating of the electromagnetic induction ring 5, the outer opening plate 6 and the inner opening plate 7 at the center of the exhaust pipe 2, which diffuses the distribution of the heat source and exists in a dynamic form. The superposition of multiple effects further improves the heat conversion rate and heat exchange rate of the electromagnetic heating exhaust gas.

[0033] Finally, the electromagnetic induction ring 5 in the middle arc-shaped pipe section of the exhaust pipe 2 will carry the outer opening plate 6 and the inner opening plate 7 after electromagnetic heating and retract to the surface of the electromagnetic induction ring 5 again and pass through the second connecting pipe 12. Similarly, after entering the annular tube of the intake pipe 1, the outer opening plate 6 and the inner opening plate 7 will open again. At this time, the opened outer opening plate 6 and the inner opening plate 7 and the corresponding electromagnetic induction ring 5 carry a certain amount of electromagnetic waste heat, which can have a stable preheating effect on the VOCs exhaust gas that just enters the annular tube. After stable operation of the equipment, the preheating temperature can be as high as 30%-50% of the required temperature, which once again improves the utilization rate of electromagnetic heat, so as to achieve the effect of rapid heating of the VOCs exhaust gas in a short time. According to the above-mentioned implementation steps and principles, the VOCs exhaust gas after stable heating can be obtained by cycling. The subsequent exhaust pipe 2 can be connected to the (catalytic) oxidation chamber based on the existing technology to carry out a series of reactions and treatments. This article and the accompanying drawings do not make too much additional explanation.

[0034] To sum up: when the VOCs waste gas enters the interior of the intake pipe 1, it will first be preheated by the electromagnetic induction ring 5, the outer opening plate 6 and the inner opening plate 7. At the same time, the wind speed difference caused by the diameter difference between the straight pipe and the annular pipe of the intake pipe 1 and the curvature difference between the annular pipe and the arc pipe are used to cause the electromagnetic induction ring 5 to rotate without power output, and the rotation speed is determined based on the flow rate of the VOCs waste gas per unit time. Then, the heated electromagnetic induction ring 5 will reversely enter the arc pipe of the exhaust pipe 2 and stably receive electromagnetic heating. The "wind-breaking" property of the outer opening plate 6 and the inner opening plate 7 is cleverly used to form turbulence in the exhaust pipe 2 to promote the contact and heat exchange between the gas and the heat source. The electromagnetic induction ring 5, the outer opening plate 6 and the inner opening plate 7 themselves will also undergo electromagnetic induction to form a new central heat source, which diffuses the distribution of the heat source and exists in a dynamic form. The superposition of multiple effects further improves the heat conversion rate and heat exchange rate of the electromagnetically heated exhaust gas.
