Efficient exhaust gas catalytic combustion process

Abstract

The invention discloses an efficient exhaust gas catalytic combustion process. The process involves an electric control device, an induced draft fan, a purification device, a heat exchanger, a catalytic bed, an electric heating element and a dust removal flame arrestor, the process comprises the following steps that an organic gas source is fed into the purification device through the action of the induced draft fan, the organic gas source passes through a dust removal flame arrestor system firstly, then enters the heat exchanger, and is fed into a heating chamber, the combustion reaction temperature of gas is achieved through the electric heating element, then the organic gas is decomposed into carbon dioxide and water through the action of the catalytic bed, and then enters the heat exchanger, and heat exchange is carried out between the organic gas and low-temperature gas, so that the temperature of the entered gas is increased to reach the reaction temperature. According to the efficient exhaust gas catalytic combustion process, noble metal such as palladium, and platinum plating is adopted to be used as catalysts on a honeycomb ceramic carrier, the purification efficiency reaches up to 95% or above, the service life of the catalysts is long, the airflow is unobstructed, the resistance is small, automatic control is achieved through PLC control, watching of special people is not needed, and the process safety is improved through the arranged dust removal flame arrestor.

Description

technical field [0001] The invention relates to a waste gas treatment process, in particular to a high-efficiency waste gas catalytic combustion process. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life, especially chemical plants, steel plants, pharmaceutical factories, coking plants and oil refineries, etc. The exhaust gas emitted has a strong smell, which seriously pollutes the environment and affects human health. [0003] With the rapid development of industry, the discharge of organic waste gas is also increasing year by year. If it is not properly treated, it will not only pollute the surrounding environment, but also affect the health of the staff when it is more serious. The existing combustion process is The efficiency of organic waste gas treatment is poor, and automatic supplementary heating cannot be realized. During the process of organic waste gas treatment, many peo...

[0003] With the rapid development of industry, the discharge of organic waste gas is also increasing year by year. If it is not properly treated, it will not only pollute the surrounding environment, but also affect the health of the staff when it is more serious. The existing combustion process is The efficiency of organic waste gas treatment is poor, and automatic supplementary heating cannot be realized. In the process of organic waste gas treatment, many people are required to guard, not only the automation intensity is low, but also the workers are labor-intensive.
