Adjustable-frequency electromagnetic descaling instrument

Abstract

The invention discloses an adjustable-frequency electromagnetic descaling instrument, which comprises a singlechip main control board, wherein the singlechip main control board is electrically connected with a coil current and power supply voltage measuring module, an LED (Light-Emitting Diode) backlight control module, a PC (Personal Computer) communication module, an alarm module, a parameter giving unit and a current and voltage detection control unit respectively; the LED backlight control module is further connected with a lattice liquid crystal display; the singlechip main control board is connected with a coil power supply control module through a D / A (Digital to Analog) module; a coil power amplification triggering module is connected with a coil power amplifying module; and the coil power amplifying module is connected with the coil power supply control module. The descaling instrument is suitable for descaling and preventing scale under various field running environments and water quality conditions, is arranged in a field wound form, does not damage field pipelines, has the maximum output power of up to 9KW and maximum adaptation pipe diameter of 3 meters, is suitable for the maximum total water hardness of 4,000 mg / L, is suitable for being applied in medium and large-sized industrial enterprises, and is efficient and environmentally-friendly.

Description

technical field [0001] The invention relates to a descaling and antiscaling device for industrial water equipment, in particular to a frequency modulation electromagnetic descaling instrument. Background technique [0002] The frequency modulation electromagnetic descaling instrument is mainly used to solve the descaling and anti-scaling problems of food evaporators, boilers, circulation systems, and various water equipment such as chemical industry, petroleum, and pipelines; at present, anti-scaling and descaling are still worldwide There are two main types of descaling and antiscaling technologies used worldwide, namely chemical descaling and physical descaling. [0003] (1) Chemical descaling: The more widely used method of descaling and antiscaling is to add chemical agents with antiscaling function (ie antiscaling agent) and ion exchange method in water. The scale inhibition mechanism of the scale inhibitor is to inhibit the normal growth of various scaleable grains in...

Problems solved by technology

[0004] There are three main disadvantages in chemical descaling: A. High production cost: A medium and large-scale related production enterprise, such as a power plant or a sewage treatment plant, spends at least hundreds of thousands of yuan or as much as 100,000 yuan of antiscalant for descaling and anti-scaling every year. Millions of RMB

B. There is a pollution problem: due to the need to add chemicals to the production equipment, the environment or equipment must be polluted or corroded to varying degrees.

[0005] (2) Physical descaling: chemical descaling has insurmountable difficulties such as high cost, pollution and strong pertinence

[0010] The biggest disadvantage of the domestic descaling instrument is that the on-site pipeline must be cut off during installation, unless it is a new project, which is not allowed for some enterprises that have already been in operation; in addition, the domestic descaling instrument is not suitable for the small range of pipe diameter and water hardness. Neglected shortcomings, which largely limit the application of domestic descaling instrument, especially in the field of poor water quality conditions (such as oil extraction) and the need for large-diameter pipelines (such as thermal power plants, the diameter of the pipeline is about 2.5 meters) occasions , the existing domestic descaling instrument is beyond the reach, and the domestic descaling instrument is only suitable for the application of small and medium-sized enterprises
