Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] At the beginning of the design of the existing blast furnace blower, there are great limitations in the monitoring method of important parameters that control the shutdown of the blower. For example, when the temperature of the motor bearing and the fan bearing are abnormal, only a simple "delay" is used. Filter mutation signals, that is, once the temperature acquisition module responsible for collecting temperature is abnormal due to malfunction or disconnection, as long as the temperature reaches the shutdown standard, the blast furnace blower will be shut down, and these temperature abnormalities are not the fault of the blast furnace blower itself Caused, but caused by the failure of the temperature acquisition ...

Abstract

The embodiment of the invention discloses a blast furnace blower temperature monitoring method and system and relates to the technical field of monitoring. The blast furnace blower temperature monitoring method comprises the steps that the current temperature of a temperature detecting point is periodically collected through a temperature collecting module and is compared with a preset alarming temperature, and the temperature monitoring result of the temperature detecting point is generated; and the temperature difference absolute value is calculated through the current temperature of the temperature detecting point and the historical temperature of the temperature detecting point and is compared with a preset jumping alarming temperature, and the temperature jumping monitoring result of the temperature detecting point is generated. The condition that the temperature of the temperature detecting point is jumped due to self breakdown of the temperature collecting module is eliminated, the problem that a blast furnace blower stops due to non-self breakdown of the blast furnace blower is solved, and meanwhile, the condition that maintenance personnel of the temperature collecting module confirm the breakdown condition and overhaul the device is facilitated.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a method and system for monitoring the temperature of a blast furnace blower. Background technique [0002] At the beginning of the design of the blast furnace blower, there is a big deficiency in the monitoring of the parameters that control the blower to stop. When the collected motor bearing temperature, fan bearing temperature, etc. reach the shutdown temperature, the blast furnace blower will be shut down, regardless of whether it is caused by the failure of the blast furnace blower itself or the temperature acquisition module that collects the temperature due to malfunction or disconnection. Therefore, due to The failure of the temperature acquisition module itself caused the shutdown of the blast furnace blower, which had a great impact on the production of the blast furnace. Contents of the invention [0003] In view of this, the application provides a blast furnace...
