Description

Technical Field

[0001] The invention relates to the technical field of fan flow regulation, and in particular to a pipeline flow control device for a steel plant fan network and a monitoring system thereof. Background Art

[0002] Steel mills usually refer to factories that produce steel. As the cornerstone of national industrialization, the development of the steel industry has always been given priority. Therefore, research and improvement on the deficiencies of steel mill production equipment has been ongoing. For example, for main exhaust fans, tail / finished product dust removal fans, ore chute dust removal fans, iron-making yard dust removal fans, coal injection fans, combustion-supporting fans and other necessary equipment for multiple production processes in steel mills, field investigations have found that most fans are operating in serious biased conditions with very low operating efficiency. After investigating the reasons, it was found that the real-time flow rate adjustment of the fan network accounted for a large proportion.

[0003] In the prior art, the problem of flow regulation is mostly solved by using a combination of an adjustment structure and a flow meter to adjust and monitor the flow. However, in actual use, the displacement deviation of the adjustment structure under long-term airflow impact and the detection deviation of the flow meter will cause a certain deviation between the acquired data and the actual situation, and the best effect cannot be achieved. This is also an inevitable shortcoming of the prior art that uses a single technical means of regulation and monitoring. Therefore, in response to the above-mentioned problems in the prior art, the present application will provide a pipeline flow control device for a steel plant fan network and a monitoring system thereof to solve them.
