Abstract

The invention discloses an energy-saving high-pressure fluidization fan device for a circulating fluidized bed boiler. The device comprises a motor, a coupler, a transmission seat and a fan which are sequentially in transmission connection, an electromagnetic disc is arranged on a base of the transmission seat, a magnetic suction cup is arranged on a center shaft of the fan, and the electromagnetic disc and the magnetic suction cup are oppositely arranged and generate magnetic repulsive force. According to the energy-saving high-pressure fluidization fan device for the circulating fluidized bed boiler, when the center shaft axially moves due to the pulling force of the fan, the electromagnetic disc is powered on, magnetic repulsive force is generated between the magnetic suction cup and the electromagnetic disc, and the axial pulling force of the fan on the center shaft is balanced through the magnetic repulsive force, so that the axial movement of the center shaft is reduced, abrasion is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to thermal power generation technology, in particular to an energy-saving high-pressure fluidized fan device for a circulating fluidized bed boiler. Background technique [0002] In the transportation of pulverized coal and flue gas for thermal power generation, fans are the core power transmission devices, such as fluidized fans for conveying pulverized coal, axial flow fans for conveying flue gas circulation, etc., due to the peak regulation requirements of thermal power As well as the adjustment needs of various cycles of its own, the fan needs to control the speed more frequently. [0003] For example, the authorized announcement number is CN201372944Y, the name is "Induced Fan for Circulating Fluidized Bed Boiler", and the authorized announcement date is a utility model patent on December 30, 2009, which provides an induced draft fan for circulating fluidized bed boiler, including The casing, the impeller, the transmission g...
