Description
Affiliated technical field
The utility model relates to a kind of descaler, relates in particular to a kind of a kind of descaling equipment that prevents internal tank generation incrustation scale that reaches by Power Electronic Technique.
Background technology
In industrial environment, the inside of various pipelines and container very easily forms incrustation scale, and the inside of especially various interchanger and boiler, due to the conversion of the conditions such as water body concentration-temperature pressure, makes solute supersaturation in water body, separates out form hard incrustation scale in the inside of container.The incrustation scale forming is hard calcite crystal structure, hard abundant, is difficult to remove easily.Fouling meeting is to pipeline, interchanger, and boiler, the equipment such as cooling tower cause serious harm, cause line clogging, and heat exchange efficiency declines, and the corrosion of internal tank.The electronics that uses at present physical method to solve incrustation scale problem develops very fast, but all exist cost higher, the shortcoming that routine maintenance consumption is larger, and also descale effect is undesirable, for varying environment and water quality bad adaptability, easily appearance is useful herein, the situation that the other side is useless, and existing physics scale removal apparatus installation is complicated in addition, and under different scale removal environment, need existing equipment to transform, such as needs installing electrodes or again transform pipeline.
Summary of the invention
The purpose of this utility model is to provide a kind of electric magnetic incrustant remover, can effectively remove incrustation scale.
The utility model solves the technical scheme that its technical problem adopts: comprise wiring board one, wiring board two, coil, LCM display unit, direct-current switch power supply; Wiring board one one end connecting coil, the other end connection line plate two, is powered by direct-current switch power supply; Many group coils from parallel connection of coils are wrapped in pipeline external; Wiring board two the other ends connect LCM display unit; Wiring board one consists of H bridge chip L298N in parallel, has higher current capacity, by direct-current switch power supply, is powered, and circuit card one produces PWM rectangle square wave; The rectangle square wave that wiring board one produces acts on the coil that is wrapped in pipeline, forms the electromagnetic field of certain frequency; The frequency of circuit card one is controlled by circuit card two, and the adjustable rectangle square wave of circuit card two output, samples to the electric current of coil on pipeline and voltage simultaneously, and result is reflected on the LCM display unit being attached thereto; Circuit card two consists of micro-chip, realizes the control of PWM by program, also has Presentation Function and warning function simultaneously.LCM display unit shows the working order of electric magnetic incrustant remover.
After the utlity model has one-step installation, can realize non-maintaining low cost movement, and useful range is large, can significantly improves circulation efficiency and the heat exchange efficiency of system.
Accompanying drawing explanation
Accompanying drawing is the utility model schematic diagram.
In figure: 1 is coil; 2 is direct-current switch power supply; 3 is circuit card one; 4 is circuit card two; 5 is LCM display unit.
Specific embodiments
As accompanying drawing, a kind of electric magnetic incrustant remover comprises wiring board 1, wiring board 24, coil 1, LCM display unit 5, direct-current switch power supply 2; Wiring board one 3 one end connecting coils 1, one end connection line plate 24, is powered by direct-current switch power supply 2; 1 parallel connection of many group coils is wrapped in pipeline external; Wiring board 24 the other ends connect LCM display unit 5.
Wiring board 1 consists of H bridge chip L298N in parallel, has higher current capacity, by direct-current switch power supply, is powered, and circuit card one produces PWM rectangle square wave; The rectangle square wave that wiring board 1 produces acts on the bridging coil 1 that is wrapped in pipeline, forms the electromagnetic field of certain frequency; The frequency of circuit card 1 is controlled by circuit card 24, and the adjustable rectangle square wave of circuit card 24 output, samples to the electric current of bridging coil on pipeline 1 and voltage simultaneously, and result is reflected on the LCM display unit 5 being attached thereto; Circuit card 24 consists of micro-chip, realizes the control of PWM by program, also has Presentation Function and warning function simultaneously.LCM display unit 5 shows the working order of electric magnetic incrustant remover.
The utility model produces the rectangle square wave of 1000 hertz to 100000 hertz by electronic circuit, this rectangle square wave acts on many groups of coils in parallel 1 that are wrapped in pipeline outer wall, the higher frequency electromagnetic field of the corresponding corresponding water quality of the interior generation of coil 1, under the effect of electromagnetic field, in pipeline, produce corresponding electric current eddy current, because crystal grain in pipeline can form double electrical layers, be that crystal grain can be with certain static charge, under the effect of high-frequency current eddy current, the effect that static charge is subject to power forces the structure of electrostatic double layer to be subject to corresponding impact, charged crystal grain can be subject to the effect of electrical forces simultaneously, cause crystal grain to distort in the process of crystallization, the incrustation scale form forming is changed, from original crystalline structure closely, become loose aragonite structure, under the effect of current, loose incrustation scale can be pulled away, be difficult to form the hard scale that is attached to container inner wall.
After the utility model one-step installation, can realize non-maintaining low cost movement, and useful range is large, its useful range is after pipeline coil 200 meters, can significantly improve circulation efficiency and the heat exchange efficiency of system.
