An air filter device for a gas-electric dual-drive induced draft fan

technical field

The utility model relates to the technical field of induced draft fans, in particular to an air filter device for a gas-electric dual-drive induced draft fan.

Background technique

The induced draft fan is a device that generates negative pressure through the rotation of the impeller and then extracts air from the system (equipment). It is generally installed at the end of the boiler to extract the hot flue gas in the furnace. In daily life, ventilators are usually divided into induced draft fans (for negative pressure use) and blowers (for positive pressure use) according to the positive and negative pressure use methods. Induced fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces; cooling and cooling of air conditioning equipment and household appliances Ventilation; drying and selection of grain; wind tunnel wind source and inflation and propulsion of hovercraft, etc. The working principle of the induced draft fan is basically the same as that of the turbo compressor, but because the gas flow rate is low and the pressure changes little, generally there is no need to consider the change of the gas specific volume, that is, the gas is treated as an incompressible fluid.
