Frequency Conversion Dirt-proof And Dirt-remover Instrument Research

Dirt phenomena are very common, if not add listen, harm extremely serious boiler, such as scale will reduce the heat transfer efficiency and heat exchange equipment, increase the heat loss, increase water resistance to flow down, forcing boiler load operation, can cause boiler overheating water-wall tubes, resulting in the pipe bulge and pipe explosion accident, also can cause corrosion of metal happen sediments. These are virtually increased equipment operation and maintenance costs, causing the waste of resources.IN energy conservation and emission reduction of already into mainstream today, how dirt-proof & dirt-remover anti-scaling appear granted. By the turn of the last century, people have begun to scale the emergence mechanism, scale and control measures to harm a thorough study and using various physical and chemical methods to reduce scale formation. These methods can be classified into two categories: physics class method and chemical class methodsUse frequency electromagnetic field on the treatment of water msp430f247 frequency dirt-proof & dirt-remover instrument is produced for the core components, the frequency of square wave signal can be changed, then by square wave signal IR2110 (high voltage side suspension driver cabin light coupling isolation and electromagnetic isolation) the output to H bridge by driving circuit, drive circuit after bigger current frequency output can be the signal to coil square. The power of the power supply,1 is MCU, while all the devices to affiliated; Power 2 is give H bridge driving circuit, in order to improve the power supply voltage and current pulse, expand output power; Scan frequency and related data for deposit memory, after startup MCU calls, to produce the corresponding frequencies of square wave signal; The keyboard and displayed as human-computer interaction interfaces, used to set your password, working voltage, current, and working frequency work work, such as parameters; U, I voltage current sampling is used to regulate the power supply voltage driving circuit of electric current feedback channel; Through the MCU control digital potentiometer, thus changing the value of power 2, and adjust the power circuit parameters of voltage and current, then can change the output pulse amplitude, achieve output power can be adjusted.After constant commissioning dirt-proof & dirt-remover apparatus has meet design requirements, achieve the expected effect. After completing the dirt-remover &dirt-proof instrument operation is simple and easy to use.
