Abstract

The invention discloses a fault early warning method and device for desulfurization equipment, and relates to the technical field of fault detection. The method comprises the following steps: acquiring target operation parameters corresponding to desulfurization equipment; determining a running state corresponding to the desulfurization equipment according to the target running parameters; determining to-be-analyzed equipment, determining a target analysis mode according to the to-be-analyzed equipment and the operation state, and obtaining first monitoring data; comparing the first monitoring data with preset monitoring data; and when the first monitoring data is inconsistent with the preset monitoring data, determining that the to-be-analyzed equipment is in a fault state, generating early warning prompt information according to the fault state, and displaying the early warning prompt information to a user, so that the user processes the to-be-analyzed equipment according to the early warning prompt information. By implementing the technical scheme provided by the invention, the problems of inaccurate fault position judgment based on the waste gas detection result and low troubleshooting efficiency in the prior art are solved.
