Embodiment Construction

[0025] Below, the multi-parameter control system of the dust removal fan and the modification method of the dust removal system of the present invention will be described in detail in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the dust removal fan multi-parameter control system of the present invention includes an intelligent controller 1 , a governor 2 , a dust sensor 3 and a wind speed sensor 4 . Wherein, the intelligent controller 1 is arranged outside the dust removal system, and a PLC controller or a single-chip controller can be selected as the intelligent controller 1 . The input end of the governor 2 is connected to the intelligent controller 1, and the output end of the governor 2 is connected to the power input end of the dust removal fan (not shown in the figure).

[0027] Such as figure 1 and 2As shown, the dust sensor 3 is installed at the dust collection port 5 of the dust removal system where the dust removal fan is locate...

Abstract

The invention relates to the field of dust removal fan control, in particular to a dust removal fan multi-parameter control system and a method for modifying a dust removal system. In order to solve the problems that energy waste, the high production cost, potential safety hazards and the like exist in an existing dust removal system, the dust removal fan multi-parameter control system is provided. According to the dust removal fan multi-parameter control system, dust sensors are arranged at dust collection openings and used for detecting the dust concentrations of the dust collection openingsand sending the dust concentrations into an intelligent controller; air speed sensors are arranged in dust collection pipelines and used for collecting air speed values in real time and sending the air speed values into the intelligent controller; a speed adjuster is connected with the intelligent controller and a dust removal fan; and the intelligent controller calculates out a target air speedvalue F and screens out the minimum air speed value F1, and the speed adjuster is utilized for dynamically adjusting the rotating speed of the dust removal fan according to the comparison result of the target air speed value F and the minimum air speed value F1 till the minimum air speed value F1 and the target air speed value F are equal. According to the dust removal fan multi-parameter controlsystem, the rotating speed of the dust removal fan is dynamically adjusted and controlled, energy waste is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of dust removal fan control, in particular to a dust removal fan multi-parameter 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 margin at the beginning of...
