Description

technical field [0001] The invention belongs to the technical field of filtration, and in particular relates to a manufacturing process of a filter element of a boiler air filter device. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. In the field of heavy industry, most manufacturing enterprises need to use high heat and high pressure equipment, such as boilers. Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . The combustion of the boiler requires a large amount of oxygen from the air for auxiliary combustion. In order to improve the combustion efficiency, a grid burner is generally used. [0003] The grid burner absorb...
