Simulation of magnetic system of apparatus of magnetic water treatment for boiler greenhouse production

Abstract

For agricultural enterprises specializing in the cultivation of greenhouse vegetables, one of the problems is deposition of salts on the surfaces of the heat exchange equipment. The amount of these salts depends on their content in the water used for this. A layer of scale of one millimeter leads to excessive fuel consumption for heating water up to 10 %. The main way to combat the deposition of salts is chemical. This method is effective, but it has a strong environmental impact. Least of all the environment is affected by physical methods. Of all the physical methods, the most promising method is magnetic exposure to water. Analysis of the existing designs of magnetic water treatment devices revealed their shortcomings. The main disadvantage is the presence of a narrow gap, in which the treatment with a magnetic field of water takes place. This gap contributes to reduced performance and reliability during operation. The proposed apparatus makes it possible to eliminate this drawback by using magnetic scattering fluxes when treating water. Water treatment with a magnetic field occurs throughout the cross section of the impact zone, which is similar to the cross section of the supply pipe. The modeling of the apparatus is carried out using modern computer programs based on the finite element method. The main task in streamlining the design of the magnetic system of the apparatus is to obtain maximum values of magnetic induction in the water treatment zone. The mechanism of action of a magnetic field on water is not fully understood. Each new device should undergo experimental research on the effective effect on water.
