Problems solved by technology

The key equipment in the anti-corrosion system is the heat-drying fan. The dehumidification effect of the traditional heat-drying fan becomes worse as the speed of the adsorption rotor increases; and the speed of the adsorption wheel has an upper limit. Continue to dehumidify

Abstract

The invention provides a hot dry fan and a control method thereof. The hot dry fan comprises a fan main body, an air inlet pipe, a humidity monitoring instrument, a controller and an adsorption rotating wheel; the air inlet pipe is communicated with the interior of the fan main body, and the humidity monitoring instrument is arranged at an inlet of the air inlet pipe; the adsorption rotating wheel is arranged in the fan main body, and the adsorption rotating wheel and the humidity monitoring instrument are electrically connected with the controller; the humidity monitoring instrument is used for acquiring the current air inlet humidity of the air inlet pipe; and the controller is used for adjusting the current rotating speed of the adsorption rotating wheel according to the current air inlet humidity of the air inlet pipe. The humidity measurement by personnel can be avoided, the number of opening times during operation of a to-be-dehumidified device is reduced, the possibility of foreign matter entering is reduced, meanwhile, the humidity measurement accuracy is guaranteed, the problem that the hot dry fan operates in a high-load state for a long time is effectively solved, the humidity stability in the to-be-dehumidified device is guaranteed, and meanwhile, the personnel can obtain the internal humidity information of the to-be-dehumidified device at any time, and the dehumidification effect of the to-be-dehumidified device is guaranteed.

Description

technical field [0001] The disclosure belongs to the technical field of fans, and in particular relates to a heat-drying fan and a control method thereof. Background technique [0002] The installation period of the high temperature gas-cooled reactor nuclear power plant demonstration project is long, the interval between the completion of the installation of the steam turbine and the first run-in is long, and the site is located in the coastal area with high humidity, so the anti-corrosion maintenance of the steam turbine is particularly important. The key equipment in the anti-corrosion system is the heat-drying fan. The dehumidification effect of the traditional heat-drying fan becomes worse as the speed of the adsorption rotor increases; and the speed of the adsorption wheel has an upper limit. Continue to dehumidify. Contents of the invention [0003] The present disclosure aims to solve at least one of the technical problems existing in the prior art, and provides a...
