Problems solved by technology
[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

Embodiment Construction
[0031] The present invention is described in further detail below with embodiment:
[0032] Such as figure 1 Shown, the present invention comprises the steps:
[0033] Step 1, the system starts and initializes parameters;
[0034] Step 2, high-frequency signal generation step: the single-chip microcomputer controls the DDS chip, and the DDS chip generates a high-frequency signal of 6-12MHz; the frequency of the signal generated by the DDS chip starts at 6MHz, and increases to 12MHz at a certain time interval with an increase of 0.5MHz , then return to 6MHZ, and then increase to 12MHz at a certain time interval with an increment of 0.5MHz, and change cyclically according to this rule.
[0035] Step 3, send the generated high-frequency signal to the amplifying circuit for amplification; the amplifying circuit includes a primary amplifying circuit and a secondary amplifying circuit; the primary amplifying circuit amplifies 50mv to about 10v, and the secondary amplifying circuit...

The invention discloses a sweep-frequency electronic water treatment method based on a single chip microcomputer. The sweep-frequency electronic water treatment method comprises the following steps: step 1, starting the system and initializing parameters; step 2, high-frequency signal generation step: controlling a DDS (direct digital synthesizer) chip by a single chip microcomputer, and generating 6-12 MHz high-frequency signals by the DDS chip; step 3, sending the generated high-frequency signal to an amplifying circuit to amplify; step 4, emitting the high-frequency signal; step 5, executing the display step. According to the method, an electromagnetic descaling technology is adopted, and the single chip microcomputer is adopted to control the DDS chip to generate a 6-12 MHz high-frequency signal about 400V for descaling. The water treatment method is of obvious sterilization and algae removal functions; besides, the high-frequency signal within a certain range of frequency can meet the processing requirement of different water quality and different concentration scales, so that the scale treatment is thorough, and labor and material resource are saved.
Description
technical field [0001] The invention relates to a water treatment method, in particular to a frequency-sweeping electronic water treatment 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 (containing so...
