Abstract

The invention discloses a control method and a control device of a desulfurization system. Wherein, the method includes: obtaining the bearing temperature of the booster fan in the desulfurization system detected by multiple temperature measuring elements, the booster fan corresponding to the multiple temperature measuring elements; when the bearing temperature of the booster fan satisfies the preset condition Under the condition, control the booster fan to stop running; after the booster fan stops running, control the recirculation damper of the desulfurization system to open. The invention solves the technical problem that the operation of the boiler unit is unstable due to the misoperation of the booster fan when the existing desulfurization system operates without a bypass.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a control method and a control device for a desulfurization system. Background technique [0002] The desulfurization system can fix the sulfur element in the coal into a solid with calcium base to prevent the formation of sulfur dioxide during combustion. According to relevant technical standards, the desulfurization bypass baffle in the desulfurization system needs to be blocked. However, after the desulfurization bypass is blocked, the desulfurization system is directly connected in series with the main engine of the boiler, and starts and stops synchronously. After the desulfurization bypass baffle is blocked, the entire desulfurization process has high requirements on the synchronization between the desulfurization system and the boiler main engine. For example, malfunctioning or tripping of the desulfurization booster fan may lead to unstable operation of the boiler unit....
