Description

Technical Field

[0001] This utility model belongs to the field of scale inhibition technology, and in particular relates to an electromagnetic scale inhibition device. Background Technology

[0002] With the large-scale application of industrial circulating water systems (such as cooling towers in thermal power plants, heat exchange equipment in petrochemical plants, and centralized heating networks), problems such as decreased heat transfer efficiency, increased energy consumption, and shortened equipment lifespan caused by scale deposition are becoming increasingly prominent. Traditional scale inhibition methods mainly rely on chemical agents (such as organophosphonic acids and polycarboxylic acid scale inhibitors). Although they can inhibit scale formation in the short term, they have drawbacks such as high agent costs (accounting for 60%-75% of the total water treatment cost), environmental pollution risks (such as eutrophication of water bodies due to phosphorus emissions), and accelerated metal corrosion.

[0003] Against this backdrop, electromagnetic scale inhibition technology has become a research hotspot due to its green and environmentally friendly characteristics and low operating costs. The principle of electromagnetic scale inhibition is to change the physical binding characteristics of scale-forming ions in the water by using a microscopic eddy current electromagnetic field excited on the outer wall of a conductive pipe, thereby achieving dynamic scale prevention and removal of old scale from the inner wall of the pipe. However, when faced with situations where the water quality in the pipeline changes significantly, traditional electromagnetic scale inhibitors cannot adjust the electromagnetic parameters in real time, resulting in poor scale inhibition performance.

[0004] Therefore, it is necessary to provide an electromagnetic scale inhibition device that incorporates a water quality probe and adjusts the electromagnetic parameters in real time according to the water quality to achieve closed-loop control of scale inhibition. Utility Model Content

Both the water quality probe and the alternating electromagnetic field output module are electrically connected to the control module. The water quality probe is installed in a pipeline to detect the water quality in the pipeline. The alternating electromagnetic field output module is installed in the pipeline. The control module adjusts the microscopic eddy current electromagnetic field output by the alternating electromagnetic field output module based on the signal acquired by the water quality probe. The control module includes a power supply unit, a signal processing control unit, and an output unit. The power supply unit is connected to an external power source to power the signal processing control unit and the output unit. The signal processing control unit is connected to the water quality probe to acquire and process the signal acquired by the probe, thereby controlling the drive signal output to the output unit. The output unit is connected to the alternating electromagnetic field output module to adjust the signal output to the alternating electromagnetic field output module.

[0008] Preferably, the power supply unit includes a power transmitter that converts the input AC power into a stable DC power output to the signal processing control unit and the output unit.

[0009] Preferably, the signal processing control unit includes a signal acquisition and conditioning circuit and a control circuit connected in sequence, the signal acquisition and conditioning circuit being connected to the water quality probe, and the control circuit being connected to the output module.

[0010] Preferably, the signal acquisition and conditioning circuit converts the micro-voltage raw electrical signal output by the water quality probe into a standard and stable electrical signal.

[0011] Preferably, the control circuit controls the drive signal output to the output unit based on the water quality data collected by the signal acquisition and conditioning circuit.
