Description

Filter of scale suppressor

This new model relates to a filter element, especially a filter element of a scale suppressor.

Poly-phosphate (poly-phosphate) material can be used as drinking water scale and rust inhibitor, also known as silicophosphate crystal, Guilijing, or Guilingjing. Double phosphate products are high-tech products that can economically and effectively prevent scaling and corrosion of water supply systems.

The complex phosphate, known as the scale inhibitor crystal, is a transparent substance fired with high-temperature technology. It can be used as a water treatment agent to protect drinking water and industrial water pipelines. Scaling crystal is a water treatment agent that uses controlled release technology to protect drinking water and industrial water pipelines. The water treated with the anti-scale crystal has obvious effects in preventing corrosion and scaling of industrial pipelines and prolonging the service life of equipment. In addition, the water treated with the anti-scale crystal is a natural way to replenish minerals for the human body.

The reaction principle of the double phosphate is that the double phosphate in the scale inhibitor crystal can react with metal ions to form a soluble chelate, inhibit the formation and aggregation of calcium with carbon and magnesium carbonate, and disperse into water. The double phosphate can react with iron ions to form a protective film on the inner wall of the pipeline to achieve the effect of anti-corrosion and scale.

The United States, the United Kingdom, Japan, Europe and other countries have used complex phosphates in a large number of domestic and industrial water for scale inhibition and corrosion protection, and the product performance is stable and reliable. For example, the U.S. Food and Drug Administration (FDA) has included polyphosphate, which can be used as a colorless, odorless, and non-toxic drinking water treatment agent, into the generally recognized as safe (GRAS) catalog. For another example, the European Union requires that the concentration of phosphates in drinking water should not be higher than 0.5 ppm.

The double phosphate is suitable for pipelines of various scales, and the dissolution time is long, and the dissolution is uniform, and the replacement is easy. Therefore, the double phosphate can replace part of the resin softening equipment, and the price is cheaper than the softening regeneration salt.

The method of using double phosphate is very simple. First, put the crystal particles of double phosphate into the container, and then connect the water source. The crystal particles in the container generate Brownian motion through the impact of water flow. At this time, the medicament is released and dissolved in water and it can function normally Pharmacological effects.

Generally, hot water pipes have the following three problems: (1) Corrosion of pipelines increases the content of heavy metals in the water. For example, lead can reduce red blood cells and reduce appetite. If the human body takes 5-10mg a day, it is easy to cause poisoning; zinc may cause cancer , Leading to language barriers, pneumonia, and liver cirrhosis; iron can produce rust, pollute water quality, and affect vision; cadmium can hinder calcium absorption and cause chondrosis; (2) calcium and magnesium scaling can block pipelines, affect water supply and reduce transmission Thermal efficiency; Silica will increase the turbidity of water, cause persistent fouling, and reduce heat transfer efficiency; (3) There will be energy consumption problems. The double phosphate can be used as the savior of hot water pipes, which can solve the three problems of hot water pipes.

In terms of application range, in addition to being used as antiseptic and scale inhibitors for warm water boilers, tea water heaters, heat exchangers, water heaters, solar water heaters, etc., double phosphates are "red water", "yellow water", "tea In addition to the "scale" problem, it can also be used with ion exchange resin to make the cooling circulating water pipeline have anti-corrosion and scale inhibitors.

Crystallized scale in water heaters and other equipment to remove magnesium and calcium crystals in the water. As the water 19 flows into the filter tank 11 as shown in FIG. 1, then flows through the complex phosphate particles 12 and finally flows out of the filter tank 11, the main body of the filter tank 11 is generally cylindrical. Therefore, the number of the complex phosphate particles 12 contained in the filter canister 11 is huge, so the concentration of the aqueous solution 19 when passing through the complex phosphate particles 12 is not uniform, and the number The huge complex phosphate particles 12 quickly fail, with a life span of only about one month, which is a waste of the materials of the complex phosphate particles 12. Furthermore, if the aqueous liquid 19 enters the filter tank body 11 at a high speed, the strong water column will violently wash the complex phosphate particles 12, which will shorten the raw material validity period of the complex phosphate particles 12. Therefore, it is necessary to find a solution.
