Catalytic combustion equipment The purpose of production is to protect the environment and control industrial waste gas pollution. In industrial production, there are a large number of organic waste gases containing benzene, alcohol and ketone. It endangers the health of workers and pollutes the environment.
Catalytic combustion equipment, as a means of controlling organic waste gas pollution, has achieved considerable results in China. However, in the process of design, processing and use of catalytic combustion device, there are still some potential unstable factors and accident hidden dangers, which may lead to fire and explosion in serious cases. Therefore, the country should formulate a unified concentration control standard or design specification for catalytic combustion of organic waste gas. In addition to the above factors, from a technical perspective, the following unstable factors should also be noted:
First, the lower explosion limit of organic gas is related to temperature. Generally, the higher the temperature is, the faster the reaction speed is, and the larger the explosion limit range is. When the concentration of organic waste gas entering the catalytic combustion equipment is too high, the temperature of the catalytic combustion equipment will rise. In addition, there was no exhaust gas concentration detection and control equipment in the domestic catalytic combustion equipment before, and the lower explosion limit value of the organic exhaust gas after heating will be less than the value given in the instruction manual. In addition, the organic waste gas components in the device are mixed unevenly, which may exceed the real lower explosion limit of waste gas under high temperature conditions in some areas, so there is an explosion risk.
2. Generally speaking, under the same lower explosive limit concentration, the calorific value of organic components in most organic waste gases is the same, and the lower explosive limit per 1% contains about 1868 kJ/N · m scoops. If the combustion is complete, that is, all the calorific value is used to heat the exhaust gas itself, then 1% of the lower explosive limit of exhaust gas combustion can heat the exhaust gas at 15.3 ℃; When the concentration of exhaust gas reaches 25% of the lower explosive limit, the temperature of exhaust gas can be increased.

Pay attention when using catalytic combustion equipment. Operate according to regulations to avoid accidents.
In view of the development of volatile organic waste gas treatment technology, catalytic combustion equipment first introduces the volatile organic waste gas treatment technology, including combustion methods, such as direct combustion method, catalytic combustion method, biological method and adsorption method, and discusses the progress and application of volatile organic waste gas treatment technology.
Volatile organic waste gas is a harmful gas. Its boiling point is close to the boiling point of water. Some VOCs have boiling points at higher temperatures. At this time, the saturated vapor pressure of these organic waste gases will be higher than 133.3Pa. Under such conditions, they may become volatile organic compounds, pollute air and affect human health.
The main components of volatile organic compounds in these catalytic combustion units include sulfur hydrocarbon, oxyhydrocarbon, nitrogen hydrocarbon, halohydrocarbon, hydrocarbon and other polycyclic aromatic hydrocarbons. Due to the similar nature, it is easy to mix together and pollute the environment. These VOCs also threaten human health, enter the human body in the breath, and cause damage to human organs. Therefore, in the era of science and technology, it is necessary to control volatile organic waste gas at a certain concentration.
