Magnetic Vortex Hydrodynamic Activator (Mvhda) for Magnetic Treatment of Water Systems


It is intended for magnetic treatment of water systems with the object of increasing efficiency of heat exchange processes due to nonchemical prevention and elimination of old scale formed on heat exchange surfaces. Principle of MVHDA operation is based on experimentally discovered phenomena of physico-chemical properties of liquids treated in constant magnetic field under certain magnetic hydrodynamic flow regimes. Without magnetic water treatment hardness salts dissolved in water form a sediment on heat exchange surfaces mainly in the form of tiff but after treatment precipitate in corpore as insoluble aragonite sludge that is easily decalcified by way of sludgecatchment basin. Due to gas solubility change, particularly oxygen, immunization of heat exchange surfaces is taken place (pellicle of dark colour is formed that mainly consists of magnetite), that leads to intensity reduction of corrosive wear.

Innovative Aspect and Main Advantages

It has the following distinctive properties:

  • flowing part profile of apparatus reactor zone is profiled in such a way that allows providing necessary speed flow conditions in a working gap in wide range of changing metering flow conditions;
  • basic construction has constant magnetic system with high performance specification in stability and durability in a wide range of temperatures;
  • apparatus is provided with magnetic induction sensors for monitoring state and efficiency conditions of magnetic system;
  • shields of magnetic systems allow reducing to a minimum external influence on working settings of MVHDA in working gaps.

Areas of Application

  • Processes and equipment where magnetic hydrodynamic method can be applied;
  • Water treatment: defecation and precipitation processes, ion exchange; (installation of activators before clarifiers and filters);
  • Reactors of producing lime milk (installation of activators on water flowing for dissolution);
  • Deaerators (water treatment before deaeration);
  • Hot water supply (installation of activators before boilers and heaters);
  • Compressor houses (installation of activators in water cooling systems);
  • Oil coolers (installation of activators in water cooling systems);
  • Condensers;
  • Average payback period of MVHDA is no more than one year.

Stage of Development

MVHDA has design documentation (TY Y 28.3-31063720-001:2005) and it is produced to made to order at pilot production of IPMash NAS of Ukraine (Du5 – Du 600).

Structural circuitry of MVHDA allow designing and producing apparatus with automatic, self-stimulating and manual adjusting of constant magnetic induction in the range of working temperatures up to + 2300C and pressure up to 30 atm. for a pipeline with a diameter of Du 5 to Du-2500 mm.

Thank you for some other great article. Where else may just anyone get that type of info
in such a perfect manner of writing? I have a presentation subsequent week,
and I'm on the search for such information.
