Sweep-frequency electronic water treatment system based on single-chip computer

Abstract

The present invention discloses a sweep-frequency electronic water treatment system based on a single-chip computer, and the system comprises a power supply module, a single-chip computer, a liquid crystal display (LCD) module, a DDS (Direct Digital Synthesizer) chip, a primary amplifier circuit, a secondary amplifier circuit and a signal transmission module; the power supply module, the LCD display module and the DDS chip are connected to the single-chip computer respectively, and the DDS chip, the primary amplifier circuit, the secondary amplifier circuit and the signal transmission module are sequentially connected. The electromagnetic descaling technology is utilized in the invention, the DDS chip is controlled by using the single-chip computer to generate about 400V of a high-frequency signal having 6-12MHz for descaling, a significant sterilization function is achieved, while high-frequency signals at a certain frequency range meet requirements for the treatment of water scale with different quality and different concentrations, and the water scale can be more thoroughly treated. Manpower and resources are saved and the frequency of signals can be set at 6MHz-12MHz according to the preferable descaling performance requirements of particular water quality so as to achieve a better descaling effect.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a frequency-sweeping electronic water treatment system and method based on a single-chip microcomputer. Background technique [0002] At present, most of the total amount of industrial water is used for industrial cooling, that is, as industrial cooling water or condensed water. According to incomplete statistics, cooling water in petroleum, chemical, electric power, metallurgy and other systems accounts for more than 60% to 70% of the total industrial water. In today's increasingly tense water resources, improving the efficiency of industrial cooling water can effectively reduce the demand for water resources and alleviate the pressure on water resources. [0003] The most effective way to improve the efficiency of industrial cooling water is to reuse circulating cooling water, but a serious problem caused by reusing circulating cooling water is the accumulation of salt, and salt (co...

AI Technical Summary

Problems solved by technology

[0003] The most effective way to improve the efficiency of industrial cooling water is to reuse circulating cooling water, but a serious problem caused by reusing circulating cooling water is the accumulation of salt, and salt (containing sodium, potassium, calcium, magnesium and other salt ions ) accumulation will bring scaling and corrosion problems of heat exchange equipment

Water quality issues can lead to shortened material life and equipment not operating at full efficiency

Therefore, in order to prevent water quality problems and keep industrial equipment in an ideal state, industrial water treatment must be carried out. At present, water treatment methods can be roughly divided into mechanical treatment, chemical treatment, biological treatment, etc. Among them, chemical treatment is widely used, and traditional methods such as pickling Although the descaling and derusting tasks of water-based equipment can be completed, this will undoubtedly seriously affect the service life of the equipment and endanger the health of the staff

Many places and units adopt the method of adding chemical agents to water equipment, and the effect is remarkable, so it is very popular. However, in most cases, the process of adding chemicals is still labor-intensive and time-consuming, and the time and amount of adding chemicals are difficult to accurately grasp.

It will not only reduce the service life of sewage discharge pipes, but also pollute water resources

[0004] In recent years, different high-tech products such as electronic water processors have been continuously researched and invented at home and abroad, but the technology is not mature enough, and there are different shortcomings. Some scale treatment methods are cumbersome and it is difficult to achieve the desired effect with human participation. For example, some equipment needs to regularly check the scale concentration, determine the signal frequency and other indicators
