Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste gas treatment, in particular to a novel industrial waste gas catalytic treatment device. Background Technique

[0002] The novel industrial waste gas catalytic treatment device is mainly based on catalytic combustion technology. Using metal catalysts (such as noble metals palladium, platinum, etc.) as intermediates, the combustible substances in the waste gas are oxidized and decomposed at a lower ambient temperature, thereby being converted into harmless carbon dioxide and water. The catalytic combustion technology reduces the activation energy of the reaction, increases the reaction rate, enables the waste gas to achieve complete combustion at a lower temperature, and achieves the purpose of purifying the waste gas. The novel industrial waste gas catalytic treatment device has a wide application prospect in multiple industries. For example, in industries such as chemical industry, electric power, metallurgy, and pharmaceuticals, these industries will generate a large amount of waste gas during the production process and need to adopt efficient waste gas treatment technologies for treatment. With the increasingly severe global environmental problems, the environmental protection requirements of various countries are getting higher and higher. Industrial waste gas, as one of the important pollution sources, its treatment has become an important part of environmental protection work. The novel industrial waste gas catalytic treatment device, with its characteristics of high efficiency, energy saving, and environmental protection, meets the urgent needs of current society for environmental protection technologies;

[0003] During the use of the existing industrial waste gas catalytic treatment device, there are at least the following disadvantages: 1. The existing equipment directly conducts catalysis without dust removal, resulting in a reduced service life of the catalyst, and at the same time, the discharged gas has a large pollution and the dust causes easy wear of the equipment; 2. The existing equipment directly conducts catalysis without temperature regulation, which limits the degree of catalysis. Therefore, we introduce a telescopic mechanism for the front legs of a travel trailer. Content of the Utility Model

[0033] In this embodiment, the purification mechanism 1 includes an air inlet box 11. An air inlet 12 is opened at the upper end of the air inlet box 11. Two adsorption plates 13 are fixedly connected to the front and rear ends of the air inlet box 11 together.

A magnetic rod 146 and a plurality of fixing frames 147 are fixedly connected to the common end of the two fixed rings 145 close to each other. All the plurality of magnetic rods 146 are fixedly connected to the outer surface of the fixing frame 147. Fixing plates 148 are fixedly connected to the outer surfaces of the two fixed rings 145.

[0034] Through the above solution: The purification mechanism effectively removes particulate matter in the waste gas, such as dust, smoke, etc. These particulate matters not only occupy a large volume in the waste gas but may also have an adverse impact on the subsequent catalytic treatment process. Therefore, the dust removal function is a key step in improving the overall waste gas treatment efficiency. The particulate matter in the waste gas is likely to deposit on the surface of the catalyst, resulting in catalyst blockage and reduced catalytic efficiency. It can effectively reduce the number of particulate matters entering the catalytic mechanism, extend the service life of the catalyst, and maintain the stable operation of the catalytic mechanism. Particulate matter is one of the main components of air pollution and has a serious impact on air quality and human health. This mechanism can significantly reduce the particulate matter emissions in the waste gas, lower the concentration of air pollutants. The setting of the dust removal function can reduce the concentration of pollutants in the air, improve air quality, and reduce the risk of people suffering from respiratory diseases and other health problems. At the same time, it reduces the abrasion and blockage of the particulate matter to the catalytic mechanism and equipment, and reduces the maintenance cost and replacement frequency of the equipment. This helps enterprises reduce operating costs and improve economic benefits.

[0035] In this embodiment, the heat exchanger 4 includes a fixing block 41. Six liquid inlet pipes 42 are fixedly connected inside the fixing block 41. The six liquid inlet pipes 42 are divided into three groups, with two in each group. The group at the front is one group, the group in the middle is one group, and the group at the rear is one group. Two liquid through pipes 43 are fixedly connected to the outer surfaces of the three groups of liquid inlet pipes 42. The six liquid through pipes 43 are divided into two groups, with three in each group. The group at the upper part is one group, and the group at the lower part is one group. Connecting rods 44 are fixedly connected to the left and right ends of the two groups of liquid through pipes 43; the lower end of the fixing block 41 is fixedly connected to the heat exchange mechanism 3, and the outer surface of the liquid inlet pipe 42 is fixedly connected to the heat exchange mechanism 3. The four connecting rods 44 are divided into two groups, with two in each group. The group on the left is one group, and the group on the right is one group. The ends of the two groups of connecting rods 44 away from each other are both fixedly connected to the heat exchange mechanism 3. The liquid inlet pipes 42, the liquid through pipes 43, and the connecting rods 44 are parallel to each other respectively, and the liquid inlet pipes 42, the liquid through pipes 43, and the connecting rods 44 are perpendicular to each other.

[0036] Through the above solution: It can make full use of the heat generated during the catalytic combustion process, transfer the heat to the low-temperature waste gas entering the system through heat exchange, thereby increasing the initial temperature of the waste gas, reducing the ignition temperature of the catalyst, and reducing energy consumption. The heat recovery efficiency is high, usually reaching more than 95%, effectively reducing the energy consumption during the waste gas treatment process. At the same time, it can maintain the relative stability of the internal temperature of the system, reduce the impact of temperature fluctuations on the catalytic combustion process, and enhance the overall stability and reliability of the system.

[0037] It should be noted that the present utility model is a novel industrial waste gas catalytic treatment device. During use, first, the motor 141 is started. The motor 141 drives the rotating rod 142 to rotate, and the rotating rod 142 drives the rotating plate 143 and the ion air bar 144 to rotate. The industrial waste gas is introduced into the purification mechanism 1. After passing through the adsorption plate 13, the waste gas reaches the dust removal assembly 14. When the waste gas passes through the ion air bar 144, it will neutralize with the charges on the surface of the ion air bar 144. Whether it is positive charge or negative charge, it will be neutralized by the opposite charge, thus eliminating static electricity. At the same time of neutralizing static electricity, the high-speed impact force of the ion air flow will also remove the dust, dirt and particulate matter attached to the surface. When the dust containing magnetic substances approaches the magnetic bar 146, it will be attracted by the magnetic field and firmly adsorbed on the magnetic bar 146, improving the subsequent catalytic efficiency, effectively reducing the number of particulate matters entering the catalytic mechanism, prolonging the service life of the catalyst, maintaining the stable operation of the catalytic mechanism, and protecting the atmospheric environment at the same time. Secondly, a liquid at an appropriate temperature is introduced into the liquid inlet pipe 42. The liquid flows into the liquid delivery pipe 43 and the connecting rod 44. When the waste gas passes through the air pipe 2 and enters the heat exchange mechanism 3, due to heat transfer, the gas in the heat exchange mechanism 3 will increase or decrease in temperature to a certain extent. Subsequently, the waste gas enters the catalytic mechanism 6 through the air pipe 5 and is catalyzed after passing through the catalytic layer 8. This mechanism can make full use of the heat generated during the catalytic combustion process and transfer the heat to the low-temperature waste gas entering the system through heat exchange, thereby increasing the initial temperature of the waste gas, reducing the ignition temperature of the catalyst, and reducing energy consumption.
