End control system of dust collecting fan and transformation method of dust collecting system

Abstract

The invention relates to the field of control of dust collecting fans, in particular to an end control system of a dust collecting fan and a transformation method of a dust collecting system. In orderto solve the problems of energy waste, high production cost, potential safety hazards and the like of existing dust collecting systems, the invention provides the end control system of the dust collecting fan. The system comprises a dust sensor, an air speed sensor, a speed regulator and an electric valve, wherein the dust sensor is arranged at the dust collecting opening to collect actual dust concentration m in real time at the dust collecting opening; the air speed sensor is arranged in a dust collecting pipeline to collect the actual air speed value in real time; the speed regulator is connected with an intelligent controller and the dust collecting fan; the electric valve is arranged in the dust collecting pipeline and is connected to the intelligent controller; and the intelligent controller automatically controls start / stop of the electric valve according to m and dynamically regulates the rotating speed of the dust collecting fan by means of the speed regulator according to acomparison result of the screened minimum air speed value F1 and the target air speed value F till F1 is equal to F. The end control system of the dust collecting fan provided by the invention dynamically regulates the rotating speed of the dust collecting fan, can avoid energy waste and reduces the production cost.

Description

technical field [0001] The invention relates to the field of dust removal fan control, in particular to a dust removal fan terminal control system and a method for transforming the dust removal system. Background technique [0002] In many production sites, such as chemical industry, electronics, mechanical processing, food, cement, refractory materials, and non-ferrous metal smelting and casting, a large amount of industrial pollution dust will be emitted. If these industrial dusts are not collected or removed effectively, it will seriously pollute the production environment and directly affect the health of production personnel. [0003] In order to effectively reduce the hazards of dust, most production equipment is equipped with a dust removal system in the corresponding production links. In order to avoid insufficient pressure of the dust removal fan during the dust removal process, the dust removal fan in the dust removal system has a 10-20% margin at the beginning of...
