Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a high-concentration waste gas treatment device based on electromagnetic heating. Background Technology

[0002] Currently, high-concentration waste gases that cannot be directly emitted are generally treated by high-temperature decomposition or by decomposition with appropriate catalysts before being discharged, so that the waste gases can be emitted into the atmosphere after treatment, ensuring the environmental friendliness of industrial waste gas emissions.

[0003] Existing waste gas treatment devices that rely solely on high-temperature heating or catalytic treatment suffer from insufficient treatment effects for high-concentration waste gases, as well as inadequate preheating or excessive preheating costs in the early stages of treatment. Therefore, a high-concentration waste gas treatment device based on electromagnetic heating is proposed. Utility Model Content

[0004] To address the problems in existing technologies, this utility model provides a high-concentration waste gas treatment device based on electromagnetic heating. This device provides a set of electromagnetic heating-based treatment equipment for the purification of high-concentration waste gas, enabling the high-concentration waste gas to undergo secondary treatment via a catalyst after electromagnetic heating. This dual treatment significantly improves the purification effect of the high-concentration waste gas. Furthermore, before the high-temperature treatment of the high-concentration waste gas, heat exchange preheating is performed based on the heat of the treated gas, further increasing the oxidation reaction rate of the high-concentration waste gas and improving the treatment effect and efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is a high-concentration waste gas treatment device based on electromagnetic heating, including a heat treatment barrel, a catalyst barrel, a heat storage body and a heat exchanger. The catalyst barrel is arranged in the middle of the heat treatment barrel, the heat storage body is arranged between the inner circumference of the heat treatment barrel and the outer circumference of the catalyst barrel, and the catalyst barrel is filled with catalyst packing.

[0006] The heat treatment barrel is equipped with a heat insulation layer, and an electromagnetic coil is arranged on the inner circumference of the heat insulation layer.

[0007] By adopting the above technical solution, a set of electromagnetic heating-based treatment devices is provided for the purification of high-concentration waste gas through a component consisting of a heat treatment tank, a catalyst tank, a heat storage body, and a heat exchanger. This allows the high-concentration waste gas to undergo electromagnetic heating treatment followed by secondary catalytic treatment, thus achieving dual treatment and greatly improving the treatment and purification effect. Furthermore, the high-concentration waste gas is preheated by heat exchange based on the heat of the treated gas before high-temperature treatment, further increasing the oxidation reaction rate of the high-concentration waste gas and improving the treatment effect and efficiency.

[0008] Specifically, the heat exchanger is provided with an exhaust gas inlet at the top, an exhaust gas outlet at the bottom, a high-temperature gas inlet at the bottom of one side of the heat exchanger, and a gas outlet at the top of the side of the heat exchanger away from the high-temperature gas inlet.

[0009] The bottom of the exhaust end of the chemical agent cylinder is connected to the high-temperature gas inlet.

[0010] Specifically, the heat exchanger is provided with an exhaust gas chamber and an air chamber, which are arranged alternately and separated by a partition.

[0011] The exhaust gas chambers and the air chambers are connected in series by stainless steel pipes.

[0012] Specifically, the exhaust gas chamber is connected to the exhaust gas inlet and the exhaust gas outlet, and the air chamber is connected to the high-temperature gas inlet and the gas outlet.

[0013] By adopting the above technical solution and setting up a heat exchanger, it is convenient to exchange the heat of the gas discharged after the heat treatment barrel is heated with the initial waste gas, so as to preheat the initial waste gas, increase the temperature of the waste gas, make the organic matter in the waste gas more likely to undergo oxidation reaction with oxygen, reduce the energy and time required for combustion, and improve the treatment efficiency.

[0014] Specifically, the heat storage body is made of ceramic honeycomb bricks, the heat insulation layer is made of ceramic heat insulation cotton material, and a coil temperature control cabinet is installed on one side of the heat treatment barrel.

[0015] The beneficial effects of this utility model are as follows: The assembly consisting of a heat treatment tank, a catalyst tank, a heat storage body, and a heat exchanger provides a set of electromagnetic heating-based treatment devices for high-concentration waste gas purification. This allows the high-concentration waste gas to undergo electromagnetic heating treatment followed by secondary catalytic treatment, resulting in dual treatment and significantly improving the purification effect. Furthermore, the preheating treatment of the high-concentration waste gas before high-temperature treatment, based on the heat of the treated gas, further increases the oxidation reaction rate, thereby improving the treatment effect and efficiency. This solves the problems of insufficient treatment effect and excessive preheating costs associated with existing waste gas treatment devices that rely solely on high-temperature heating or catalytic treatment for high-concentration waste gas.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1 As shown, the high-concentration waste gas treatment device based on electromagnetic heating of this utility model includes a heat treatment tank 1, a catalyst cylinder 2, a heat storage body 3 and a heat exchanger 4. The catalyst cylinder 2 is located in the middle of the heat treatment tank 1, the heat storage body 3 is located between the inner circumference of the heat treatment tank 1 and the outer circumference of the catalyst cylinder 2, and the catalyst cylinder 2 is filled with catalyst packing 21.

[0021] The heat treatment barrel 1 is provided with a heat insulation layer 11, and an electromagnetic coil 12 is provided on the inner periphery of the heat insulation layer 11.

[0022] The present invention also includes that the heat exchanger 4 is provided with an exhaust gas inlet 41 at the top, an exhaust gas outlet 42 at the bottom, a high-temperature gas inlet 43 at the bottom of one side of the heat exchanger 4, and a gas outlet 44 at the top of the side of the heat exchanger 4 away from the high-temperature gas inlet 43.

[0023] The bottom of the exhaust end of the chemical agent cylinder 2 is connected to the high-temperature gas inlet 43.

[0024] The heat exchanger 4 is provided with an exhaust gas chamber 45 and an air chamber 46. The exhaust gas chamber 45 and the air chamber 46 are arranged alternately and are separated by a partition.

[0025] The exhaust gas chambers 45 and the air chambers 46 are connected in series by stainless steel pipes 47.

[0026] The exhaust gas chamber 45 is connected to the exhaust gas inlet 41 and the exhaust gas outlet 42, and the air chamber 46 is connected to the high-temperature gas inlet 43 and the gas outlet 44.

[0027] During use, the heat exchanger 4 facilitates the exchange of heat from the gas discharged after the heat treatment tank 1 is heated with the initial waste gas, thereby preheating the initial waste gas to increase its temperature. This makes it easier for the organic matter in the waste gas to undergo oxidation with oxygen, reducing the energy and time required for combustion and improving treatment efficiency.

[0028] This utility model also includes that the heat storage body 3 is made of ceramic honeycomb bricks, the heat insulation layer 11 is made of ceramic heat insulation cotton material, and a coil temperature control cabinet 5 is provided on one side of the heat treatment barrel 1.

[0029] In use, the output terminal of the coil temperature control cabinet 5 and the input terminal of the electromagnetic coil 12 are electrically connected by wires, which makes it easy for personnel to control the heating temperature of the electromagnetic coil 12 through the coil temperature control cabinet 5. Under normal operating conditions, the heating temperature of the electromagnetic coil 12 is 350-400℃.

[0030] In use, the power supply components in the work site provide power to the electrical components in this application. Then, the exhaust gas inlet 41 is connected to the exhaust gas discharge pipe of the chemical processing. During operation, the inside of the heat treatment tank 1 is heated by the electromagnetic coil 12. During treatment, the exhaust gas enters the exhaust gas chamber 45 through the exhaust gas inlet 41, and then enters the exhaust gas outlet 42 from the exhaust gas chamber 45 and is discharged into the bottom of the heat treatment tank 1. As the exhaust gas continues to enter, it passes through the heat storage body 3 and is heated, so that the exhaust gas is treated by high-temperature combustion. The space after combustion enters the catalyst cylinder 2. During this period, the exhaust gas that is not fully combusted will undergo secondary catalytic treatment by the catalyst packing 21. After passing through the catalyst packing 21, it enters the air chamber 46 through the high-temperature gas inlet 43 and is then discharged to the outside through the gas outlet 44, thus realizing the high-concentration exhaust gas treatment operation.

[0031] During this process, when the air after high temperature and catalytic treatment enters the air chamber 46, it can preheat the exhaust gas that has just entered the adjacent exhaust gas chamber 45. This preheats the exhaust gas, making it easier for the organic matter in the exhaust gas to undergo oxidation with oxygen when it enters the subsequent environment, thus reducing the energy and time required for combustion and improving the treatment efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
