Water treatment apparatus

Abstract

The invention discloses a water treatment apparatus, comprising a power converter, an oscillatory circuit device, and a coupling device disposed outside a pipeline. The power converter is used for converting mains supply into direct-current power in a preset voltage range, the oscillatory circuit device is used for producing a high-frequency oscillatory electrical signal by using the direct-current power and supplying the high-frequency oscillatory electrical signal to the coupling device, the coupling device is used for generating high-frequency electromagnetic wave according to the high-frequency oscillatory electrical signal, and the high-frequency electromagnetic wave is used for removing scale in the pipeline. The water treatment apparatus may provide the functions such as descaling, scale inhibiting, sterilizing and algal removal for the pipeline, is convenient to mount with no need for cutting the pipeline open, is low in running cost, small in size, small in floor area, free of contact with water and free of maintenance, can be fully automated for treatment without management by staff, is highly applicable, energy-efficient and environment-friendly, requires little electricity fee each year and is free of environmental pollution.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water processor. Background technique [0002] During the long-term water delivery process, a layer of hard deposits, namely scale, will form on the inner wall of the water delivery pipeline. Especially in areas with high water hardness, this phenomenon is more obvious. If the scale cannot be dealt with in time, descaling and anti-scaling of the pipeline will easily lead to the growth of bacteria in the pipeline and affect the water quality of the transported water. Moreover, the scale will cause the aging of the pipeline material, increase the power of water transportation, and reduce the service life of the pipeline. In severe cases, it will also cause economic losses. [0003] The existing scale treatment processes mainly include softened water process, chemical descaling process and electronic water treatment process. Among them, the softened water process can pr...

AI Technical Summary

Problems solved by technology

Among them, the softened water process can prevent scale, but cannot remove scale, and the long-term operation costs are high, such as salt consumption, electricity consumption, water consumption, labor costs, maintenance costs, and pollute the environment at the same time

Moreover, the water softening device properly controls the water hardness index, which can prevent scale, but cannot remove scale. If the softened water hardness index is not well controlled, it will not only prevent scale, but also cannot remove scale

[0004] The chemical descaling process requires regular dosing, high operating costs, corrosion to equipment and pipelines, polluting the environment, and requires professional management and maintenance. Once fluctuations in chemical concentration are found, fouling will also occur, and the operating cost is too high

[0005] Although the operating cost of the electronic water treatment process is not high, it needs to cut the pipeline, which is troublesome to install, and the electrodes that generate the electric field are in direct contact with the water. After a period of time (about half a year), due to the fouling of the electrodes, the anti-scaling effect of the electronic water will be reduced. greatly reduced, or even ineffective

At the same time, the electronic water treatment process has a very short action distance and is difficult to promote in a large area. In addition, it is inconvenient to install, effective in the short term, and ineffective in the long term, so it is used less and less in the water treatment market.
