Description

Technical Field

[0001] The utility model belongs to the technical field of incineration devices, and specifically relates to an exhaust gas incineration device for a formaldehyde production line. Background Art

[0002] The formaldehyde production line tail gas incineration device is a device used to treat and reduce the emission of harmful substances in the tail gas generated during the formaldehyde production process. The formaldehyde production process will release volatile organic compounds (VOCs) and other harmful gases including formaldehyde. If these tail gases are directly discharged into the atmosphere, they will have a serious impact on the environment and human health. The basic principle of the incineration device is to use high-temperature combustion to convert harmful substances in the tail gas into relatively harmless substances (such as carbon dioxide and water). This process is usually carried out in a high-temperature furnace, and the temperature can reach 850°C to 1200°C, which is enough to ensure that most of the harmful gases are completely decomposed.

[0003] After the exhaust gas is burned at high temperature, it is further processed by a purification system to ensure that the gas discharged into the atmosphere meets environmental protection standards. Traditional purification systems usually need to be shut down when replacing filter elements, which means that production activities must be suspended, resulting in reduced production efficiency. Even a short shutdown can result in significant production losses. Therefore, a formaldehyde production line exhaust gas incineration device is needed to solve the above problems.
