Problems solved by technology

[0006] The use of copper-zinc alloy particles with different particle diameter ratios is not disclosed in the prior art. After using copper-zinc particles with the same diameter for a period of time, it will be easy to harden, affecting the effect of chlorine removal, and when the water temperature is low, the metal The effect of the alloy on water treatment will be greatly reduced, especially the effect of chlorine removal, and the service life is short. Most of the current market is a single activated carbon filter material, which is easy to breed bacteria and has a single treatment effect

Embodiment 1

[0041] 1. First prepare copper-zinc alloy particles, the preparation method is as follows:

[0042] (1) Melting and mixing copper-zinc with a mass ratio of 5.5:4.5 in a high-temperature furnace at 1100°C;

[0043] (2) putting the melted copper-zinc alloy melt into water in a linear shape, so that the copper-zinc alloy is cooled into particles;

[0044](3) Take out the above granules in water, and dry them under anaerobic conditions at 40°C;

[0045] (4) Grinding the dried particles as a whole to obtain copper-zinc alloy particles of different diameters,

[0046] (5) the copper-zinc alloy particle obtained above is screened to obtain the copper-zinc alloy particle for water purification, and the diameter and mass percentage of the copper-zinc alloy particle for water purification are:

[0047] Diameter≤1mm 35%

[0048] 1mm≤diameter≤2mm 30%

[0049] 2mm≤diameter≤4mm 35%.

[0050] 2. According to the mass percentage, 85% of copper-zinc alloy particles, 7% of activated carbon...

Embodiment 2

[0053] The preparation of the copper-zinc alloy particles of the present embodiment and the test conditions of the filter material are the same as in Example 1, except that the filter material is composed of 90% of the copper-zinc alloy particles, 5% of the activated carbon particles, and 5% of the calcium sulfite particles. The test results are shown in Table 1.

Embodiment 3

[0055] The preparation of the copper-zinc alloy particles of the present embodiment and the test conditions of the filter material are the same as in Example 1, except that the filter material is composed of 90% copper-zinc alloy particles, 2% activated carbon particles, and 8% calcium sulfite particles. The test results are shown in Table 1.

Abstract

The invention discloses copper-zinc alloy particles for water purification and a preparation method thereof, and a water purification filter material; the diameter and mass ratios of the copper-zinc alloy particles comprise that the amount of copper-zinc alloy particles with the diameter of less than or equal to 1 mm is 35%-45%, the amount of copper-zinc alloy particles with the diameter of more than or equal to 1 mm and less than or equal to 2 mm is 25%-35%, and the amount of copper-zinc alloy particles with the diameter of more than or equal to 2 mm and less than or equal to 4 mm is 25%-35%. The water purification filter material also can comprise activated carbon particles and / or calcium sulfite particles. The hardening problem is solved by the way of combining the copper-zinc alloy particles with different diameters, and generation of a hardening phenomenon is reduced; at the same time, the activated carbon particles, the copper-zinc alloy particles and the calcium sulfite particles can be used together, so that the odor and remaining chlorine in water can be better adsorbed, and calcium sulfite can compensate the problem of non-ideal removal effect of copper-zinc alloy particles on remaining chlorine at relatively low temperature.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a copper-zinc alloy particle for water purification, a preparation method thereof, and a water purification filter material. Background technique [0002] According to national standards, qualified tap water must be sterilized and disinfected. Chlorination is an effective method to eliminate germs and microorganisms in water. It has the advantages of good bactericidal effect, convenient use, low treatment cost, and convenient operation and management. Chlorine sterilizes tap water, so that although bacteria are killed, residual chlorine often remains in tap water, and the residual chlorine in tap water usually produces an unpleasant taste, and under warm water conditions, the taste of chlorine is stronger. as obvious. It has been found through research that when people bathe in a closed bathroom, the residual chlorine in the water vapor and the harmful substances such as organic com...
