Description

Technical Field

[0001] The invention relates to the technical field of fly ash filtering equipment, in particular to a fly ash filtering device. Background Art

[0002] Fly ash is a fine solid particle in the flue gas ash produced by the combustion of fuel (mainly coal). It is a hazardous waste. Fly ash is formed when coal powder enters the furnace at 1300-1500℃ and is cooled after absorbing heat from the hot surface under suspended fuel conditions. The emission of fly ash is directly related to the ash content in the burned coal. According to my country's coal consumption situation, burning 1t of coal produces about 250-300kg of fly ash. If a large amount of fly ash is not controlled or treated, it will cause air pollution and silt up the river when it enters the water body. Some of the chemicals in it are harmful to organisms and humans. As a renewable resource, fly ash should be better recycled and utilized. It has been widely used in making cement and various lightweight building materials. However, the current fly ash filtering device has poor filtering effect, and fly ash will inevitably enter the air, which will harm people's living environment.
