Problems solved by technology

Due to the diversity and complexity of pollutants in water, this simple purification process cannot meet the requirements of purification, and various pollutants and impurities in water cannot be effectively removed
Moreover, these purification devices generally have serious defects such as low efficiency, small flow, and short life.
Some also added liquid disinfectant (ZL01222813.3, designer Luo Yan, etc.), causing secondary pollution of the purified water
Simultaneously complicated structure and crude sealing condition also cause manufacturing difficulty, easily leak and cause secondary pollution, and product cost height (US4147631, inventor S.Deines; US4591438, inventor M.Tanabe etc.; CA02470149, inventor C.Yiu ; ZL992491 87.8, designed by Liu Fumin; ZL95227611.9, designed by Zhu Guozhu; ZL200420052538.9, designed by Huang Zhenqing), and the axial flow design causes serious problems such as large fluid resistance, small water output and easy leakage due to high internal pressure ( US4680116, inventor M.Kamiwada, etc.)

preparation example Construction

[0024]In the specific preparation process, the KDF particles, immobilized substance and additives are first mixed thoroughly. The ideal mixing procedure is to mix the immobilized substance and stabilizer first, then add KDF particles and continue mixing. After mixing, the surface of KDF should be evenly covered on immobilized particles. The mixture is then filled into molds at a packing density of 0.5 to 5.0 grams per cubic centimeter, preferably 1.2 to 1.8 grams per cubic centimeter. The filled mold is heated to the melting, sintering or solidification temperature of the fixation. The way to raise the temperature is to raise the temperature gradually. First, raise the temperature to 5 to 10 degrees lower than the melting point, maintain it for 0.25 to 24 hours, and the best choice is 15 to 30 minutes, and then raise the temperature to the melting point, or 0.1 to 0.1 degrees higher than the melting point. 100°C, and keep at this temperature for 0.25 to 48 hours, the best cho...

[0035] Example 1: Preparation of immobilized KDF cylinder

[0036] KDF filter material, particle diameter 100 mesh (0.14 mm), 240 grams.

[0037] Immobilized product, polyvinylidene fluoride powder, particle diameter 35 microns, 45 grams, melting point 170°C.

[0038] Stabilizer, water, 28 g.

[0039] After the polyvinylidene fluoride powder and water are fully mixed, add KDF particles and continue to mix the surface of KDF to evenly cover the immobilized particles; fill the mixture into a mold with a filling density of 1.78 grams per cubic centimeter; heat the filled mold to 165 ℃, keep warm for 1 hour, then raise the temperature to 171°C, keep warm for 0.5 hour; apply a pressure of 0.1MP to the mold during the heating and heat preservation process; quench and demould after the heat preservation time is over. After thorough cooling, a cylindrical immobilized KDF with an outer diameter of 5 cm, an inner diameter of 2.8 cm, a wall thickness of 1.1 cm and a length of 11 cm was...

Abstract

A fluid cleaning medium for removing chlorine, organic and inorganic pollutants, heavy metals, ions, particles and bacteria from fluid is composed of a pre-filtering layer, an immobilized layer and an adsorptive filter layer. It features large effective area, low pressure loss and compact structure. Its preparing process is also disclosed.

Description

Technical field: [0001] The invention relates to the technical field of fluid purification media, in particular to a fluid purification media with an integrated structure formed by combining different materials and a preparation method thereof. Background technique: [0002] With the development of productivity and the improvement of living standards, the purification of water quality, especially the purification of daily water has become more and more important and urgent. For example, in the city's tap water supply system, particulate impurities in water pipelines, microorganisms in water, heavy metal ions, calcium and magnesium ions, organic and inorganic pollutants, especially residual chlorine, have become an urgent problem to be solved. . In order to remove various pollutants in water, a multi-stage combination of different operating units must be used to form a purification system to achieve the purpose. [0003] However, due to the limitations of the prior art, the...
