Problems solved by technology

KDF alloy filter materials are small high-purity copper-zinc alloy solid particles with high density, but from the perspective of its water purification mechanism, it actually uses only the surface part, so there are three problems in the application process : The filter material will form a certain amount of precipitates through the reaction, and these precipitates will cover the surface of the alloy, reducing the ability to remove impurities, and the density of the KDF medium is high, and the backwashing pressure is high, which may increase the cost; if no equipment is added, The accumulation of filter material may block the filter bed and affect the water flow; water treatment projects need to use a large amount of copper-zinc alloy filter material, and the initial investment is large, which is the main problem
However, the literature discloses that the water treatment equipment made of this alloy uses alloy powder as filler, which has the disadvantages of large resistance, easy clogging, and easy coverage and precipitation on the surface of the alloy, resulting in a decrease in processing capacity.
[0005] Chinese patent document CN102010070A discloses a suspended water treatment filler with a double helix structure, which is used for biochemical reactions in sewage treatment. However, the water treatment filler with this structure is used for sewage treatment, and the operating flow rate is low. Biochemical reaction is different from the water treatment technical field of the boiler water inlet device, and according to the content disclosed in the patent document, this kind of packing needs to be processed into a thin-walled structure, and when used for boiler water treatment, due to the large operating conditions The water flow rate is high, and the packing strength of the thin-walled structure cannot meet the use requirements

Description

technical field [0001] The invention relates to water treatment technology, in particular to a water treatment core component and a water treatment device using the water treatment core component. Background technique [0002] Due to fouling of the boiler, frequent accidents and increased maintenance time also affect the normal production and life. For enterprises, the long shutdown time directly affects production and reduces the economic benefits of the enterprise. Therefore, the optimal design of the core structure of industrial boiler water treatment equipment has important theoretical research value and practical significance, and has attracted extensive attention from domestic and foreign experts. [0003] At present, the relevant industrial boiler water treatment devices at home and abroad mainly include KDF filter material [US4642192, US5122274, US5135654] and PTH water processor. US Patent No. 4,642,192; 5,122,274; 5,135,654 introduced the scale inhibition mechani...
