Many people are interested in catalytic incineration Waste gas treatment equipment It is no stranger, but we may not know much about the treatment process of catalytic incineration equipment. Today's edition will describe the treatment process of catalytic incineration equipment for us:

     1. The gas entering the catalytic incineration waste gas treatment equipment shall be pretreated to remove dust, droplets and harmful components, so as to prevent blocking of the catalytic bed and poisoning of the catalyst.

     What are the treatment processes of catalytic incineration waste gas treatment equipment

     2. The gas temperature of the catalytic bed must reach the light off temperature of the catalyst used before the catalytic reaction can be adjusted. Therefore, it is necessary to preheat the intake air below the ignition temperature to reach the ignition temperature. Especially during start-up, it is necessary to preheat the cold gas, so the catalytic incineration method is suitable for the purification of continuous exhaust gas. After preheating the inlet gas during start-up, the heat of incineration tail gas can be used to preheat the inlet gas. If the waste gas is discharged intermittently, the imported cool gas tank shall be preheated every time when starting. The repeated suggestions of the preheater greatly increase the energy consumption. The preheating method of gas can be either electric hot wire or flue gas heating, and now electric heating is widely used.

     3. The reaction of catalytic incineration emits a lot of reaction heat, so the temperature of incineration tail gas is very high, and it is necessary to recover this heat. Generally, the high-temperature tail gas is communicated with the imported low-temperature gas through the heat exchanger to reduce the preheating energy consumption. The residual heat can be recovered by other methods. When the temperature of the organic waste gas discharged from the production equipment is high, such as the drying temperature of enamelled wire, insulating materials, etc. can reach more than 300 degrees, so the preheater and heat exchanger can not be set high. However, the heat of incineration tail gas should still be recovered. There are two types of catalytic incineration process flow in organic waste gas treatment: separately built process and combined process. In the separately built process, the preheater, heat exchanger and reverberator are set up as independent equipment, which are connected with corresponding pipelines. Generally, they are used in occasions with large amount of gas treatment. The combined process will preheat Heat exchange, reaction and other parts are combined and installed in the same equipment, that is, the so-called catalytic incinerator, which has compact process and small floor area, and is generally used for occasions with small gas processing capacity. Our country has finalized products of this kind of equipment, which can be selected according to the size of the gas treatment volume.

     4. The equipment for catalytic incineration is catalytic incinerator, which mainly includes preheating and incineration. In the preheating part, in addition to setting heating equipment, a certain length of preheating zone shall be adhered to to ensure uniform gas temperature distribution and ensure that the flame does not contact the catalyst when burning fuel to heat the inlet exhaust gas. In order to prevent heat loss, the preheating section should be super insulated. In the catalytic reaction part, in order to facilitate the loading and unloading of the catalyst, the assembly parts are usually divided into baskets or drawers.
