Device to electronically soften hard water

Abstract

The invention belongs to the technical field of electronic technology and water treatment, and relates to a device for softening hard water by electronic means. The device is composed of 12V direct current power supply DC, astable multivibrator, square wave oscillator, alternating electromagnetic field forming circuit and working state indicating circuit. When the hardness of the water is greater than 450 mg / L, if the softening treatment is not carried out in time, it will affect industrial production and people's daily life. The hardness of the water is too high, and it is easy to form scale in the container. If it is not removed in time, repeated drinking of the water in the container will cause health problems. In order to solve the softening problem of hard water, the present invention applies an appropriate electromagnetic field to the hard water at the entrance of the water supply system or hot water appliance by means of the alternating electromagnetic field generated by electronic means, so as to reorganize or interfere with the calcium and magnesium plasma in the water, and change the absolute value of the water in the water. Most of the original characteristics of calcium magnesium carbonate, calcium magnesium carbonate and mercury, cadmium, lead and arsenic ions make hard water achieve the goal of softening. Softening hard water electronically is far less expensive than applying chemical methods, and is environmentally friendly without any pollution.

Description

technical field [0001] The invention belongs to the field of electronic technology and water treatment technology, and relates to an electronic softening device for hard water. Background technique [0002] The hardness of water depends on the content of calcium, magnesium, iron, aluminum, manganese carbonates, sulfates and nitrates in the water. Water can be divided into soft and hard. The unit of water hardness is usually measured by converting all the salts in the water into calcium carbonate. When the calcium carbonate in water is less than 150 mg / L, it is called soft water; 150-450 mg / L When it is high, it is called hard water; when it is 450-714 mg / liter, it is high hard water; when it is greater than 714 mg / liter, it is extra hard water. The national health standard for drinking water hardness is less than 450 mg / L. [0003] When the hardness of water is greater than 450 mg / L, if the softening treatment is not carried out in time, it will directly affect industrial ...

Problems solved by technology

In industry, hard water will affect the results of chemical tests and the quality of products in industries such as papermaking, pharmaceuticals, electronics, chemicals, food and beverages, and even lead to serious consequences; in life, the hardness of water is too high. Soap does not foam and causes waste; washing clothes with hard water can easily make the textile fibers hard and brittle and damaged; bathing with hard water and washing hair can feel astringent and sticky; the hardness of water is too high, and it is easy to get stuck in the container. Scale is formed, once the scale is formed, it will waste more than 1 / 3 of the fuel for boiling water

Not only that, after the kettle or electric water heater has been used for a period of time, the inner wall will be covered with a layer of white scale. If it is not removed in time, after repeated use for boiling and filling water, more and more harmful elements will accumulate and damage the water. It may be dissolved in water again, and drinking such water will cause health problems in the human body
