Detailed Description
The present invention will be further illustrated with reference to the following examples.
Example 1.
A method for filtering, heating and purifying water is carried out by adopting a filtering, heating and purifying device shown in figure 1, raw water is input into a water cavity of a heating device through filtered water of a filter element, and is discharged as produced water after being heated.
The filter element adopts weakly acidic cation exchange resin which accounts for more than 50 wt% of the total amount of the ion exchange resin to form a filter material, and carbonate ions and bicarbonate ions in liquid are removed by filtering the ion exchange resin, so that the generation of the carbonate ions and the bicarbonate ions in the working process of the ion exchange resin is reduced, and scaling in the processes of filtering, concentrating and heating the liquid is avoided. The reason for the generation of scale during the filtration is that the strongly acidic cation exchange resin decomposes H+And the negative electricity groups contained in the resin body adsorb calcium and magnesium ions in the solution, so that scaling is caused. The method of the invention has the different idea from the conventional idea of adopting strong acid cation exchange resin in the prior art, reduces the generation of bicarbonate ions and carbonate ions in the solution, thus losing the scaling condition even if the solution contains calcium, magnesium and other ions.
Specifically, the filter material is composed of a weakly acidic cation exchange resin in an amount of 50 wt% or more based on the total amount of the ion exchange resin. The weakly acidic cation exchange resin removes bicarbonate ions and a part of hardness ions in water well, so that the remaining hardness ions in water do not scale even when heated.
The weakly acidic cation exchange resin may be a resin containing carboxylic acid groups-COOH, phosphoric acid groups-PO2H2And a phenolic hydroxyl group Ar-OH. The skeleton component of the weakly acidic cation exchange resin comprises a polystyrene resin and/or a polyacrylic acidAnd (5) structure.
The heating device is a kettle, a water bar, an electric water heater, a coffee machine or a water dispenser, and the heating temperature in the water cavity of the heating device is 40-100 ℃. Preferably, the heating temperature in the water chamber of the heating device is 60 to 99 degrees celsius.
The filtered water produced by the weak acid type cation exchange resin is acidic and has poor taste. According to the invention, through combination with the heating device, after filtered water is heated by the heating device, carbonic acid components in the water are effectively volatilized, so that the acidity of the water is controlled, the taste is close to the center or alkaline, and the water is more suitable for drinking.
The filtering and heating water purification method adopts the weakly acidic cation exchange resin which accounts for more than 50 wt% of the total amount of the ion exchange resin to form the filter material, and the carbonate ions and the bicarbonate ions in the liquid are removed by filtering the ion exchange resin, so that the scaling generated in the processes of filtering, concentrating and heating the liquid is avoided, and the scale removal capacity of the filter element is improved. The filtered water is heated by the heating device, so that the carbonic acid component in the water is effectively volatilized, the acidity of the water is controlled, the taste is close to the center or alkaline, and the water is more suitable for drinking.
FIG. 2 shows the results of measuring the detergency capacity of a weakly acidic cation exchange resin alone as a filter medium and a weakly acidic cation exchange resin alone as a filter medium, and shows that the detergency capacity of the weakly acidic cation exchange resin is much higher than that of the weakly acidic cation exchange resin alone for the same gram number of resins. Therefore, the technical scheme of the invention can obviously improve the descaling capacity of the filter element.
The method can also effectively remove alkalinity to obtain alkalescent filtered water suitable for drinking. FIG. 3 is a graph showing the results of comparing the removal of alkalinity of water using a strongly acidic cation exchange resin as a filter material with that using a weakly acidic cation exchange resin as a filter material under the same conditions.
Experiments prove that the Ph value of filtered water after being filtered by the filter element mainly made of the weak acid cation exchange resin is between 5.2 and 5.8, and the Ph value of produced water after the filtered water is subjected to heating treatment is between 6.8 and 7.5. Therefore, the method of the invention can not only improve the scale removal, but also remove the alkalinity, and obtain clean water with good taste.
