结论:在使用供热节能器后对各项指标有显著改善。Conclusion: After using the heating economizer, the indicators are significantly improved.

本发明的工作原理为:The working principle of the present invention is:

该合金材料利用各种金属之间电动势的差异,会在材料的周围形成一个强大的电子云,尤如一个电化学催化体,当流体通过供热节能器时,在紊流的状态下与合金材料接触,合金材料放出大量的电子进入到流体中,从而使流体中的矿物质(主要是阳离子,比如钙、镁等金属离子)极化,即钙镁等离子得到电子,经过供热节能器的水不断产生偶极子,降低阴阳离子的亲和力,改变地暖系统各物质的点位,增加溶解度,并形成弱电场,使液相中的胶体物质呈悬浮状态,不易聚集吸附于管壁上,使各种离子与杂志不易形成垢、生物粘泥,抑制菌藻类,并能使已结的垢脱落、生物粘泥化解,降低水的硬度,水清澈度得到了提高,并且,能使地暖系统的循环水的“大理石型”结构向“文石型”结构转变,利于水垢的溶解,防止结垢的生成,显著降低能耗,提高能效,并且延长了设备的使用寿命。The alloy material uses the difference in electromotive force between various metals to form a strong electron cloud around the material, such as an electrochemical catalyst. When the fluid passes through the heating economizer, it interacts with the alloy in a turbulent state. When the material contacts, the alloy material releases a large amount of electrons into the fluid, thereby polarizing the minerals (mainly cations, such as calcium, magnesium and other metal ions) in the fluid, that is, calcium and magnesium ions get electrons, and pass through the heating energy saver. Water constantly generates dipoles, reduces the affinity of anions and cations, changes the site of each substance in the floor heating system, increases solubility, and forms a weak electric field, so that the colloidal substances in the liquid phase are in a suspended state, which is not easy to aggregate and adsorb on the tube wall, so that the Various ions and magazines are not easy to form scale, biological slime, inhibit bacteria and algae, and can make the formed scale fall off, the biological slime is dissolved, the hardness of the water is reduced, the water clarity is improved, and it can make the floor heating system. The "marble-type" structure of the circulating water is transformed to the "aragonite-type" structure, which is conducive to the dissolution of scale, prevents the formation of scale, significantly reduces energy consumption, improves energy efficiency, and prolongs the service life of equipment.
