Iodine-polysaccharide complex resin water purification device and preparation method thereof

The invention relates to an iodine-polysaccharide composite resin water purifying device and a preparation method thereof, in particular to a water absorbing effect, a bactericidal effect, a sustainable release of iodide, a straw-type structure, convenient use, no electricity for use in the field, no residue. The iodine-polysaccharide complex resin water purification device which does not harm the human body and enhances the flow and fluency, and the preparation method thereof.

There are three types of traditional water purification devices: the first type of boiling: this method is more time-consuming, and it requires fuel and water containers (if it is used in a disaster area, large buckets or containers may be needed to supply sufficient drinking water), the most important It takes time to boil, and it takes time to cool down to a drinkable temperature after boiling. This method is not conducive to the need to provide large amounts of drinking water in the suburbs or disaster areas at any time.

The second type of electronic filtration: for example, reverse osmosis is a type of electronic filtration, but this method must be powered by electricity, pressurized by reverse osmosis filtration, and requires a high pressure water storage tank (with considerable weight), also produced Not conducive to the use of suburban or disaster areas.

The third type of filter: This method is mostly used to filter impurities in liquids (in some areas, the water quality is poor, users will install filter-assisted filtration), but the filter can only filter impurities when the liquid passes. It is not possible to sterilize immediately, so the filtered water still needs to be boiled again and may not be consumed directly.

Referring to the twentieth figure, there is currently a water filtering device in which an iodine resin portion 82 is provided in the suction pipe 81, so that when the liquid passes, the iodine 821 is released to sterilize the liquid, but this design, iodine The release rate of 821 (see Figure 21) was slow during the initial period. Referring to the "second curve L2 (ie, iodine-containing curve)" in Figure 17, the iodine concentration released from 0 to 1 minute in the initial period is increased from 0 to 0.15 (mg/L). At this time, since the iodine concentration is low, the sterilization effect is poor, and the liquid cannot be sterilized. When the time is between 1 and 3 minutes, this iodine The concentration is gradually increased, and the bactericidal effect is gradually increased; after 3 minutes, the iodine concentration is close to 0.2 (mg/L), which is sufficient for effective sterilization. That is to say, in the initial stage of inhalation of water, the conventional water purifying device may have a risk of immersing the bacteria-containing liquid because the iodine concentration is relatively low and the bactericidal effect is insufficient.

In view of this, a technique for solving the above disadvantages has been developed.

In particular, the problems to be solved by the present invention include: the conventional device is unable to absorb water to exert a bactericidal effect, the boiling type is not favorable for use in the suburbs or the disaster area, the reverse osmosis requires electric power is also unfavorable for field use, and the traditional iodine containing iodine extract releases iodine. The problem is that the speed is slow and it is not possible to sterilize immediately.

The technical means for solving the above problems is to provide an iodine-polysaccharide complex resin water purification device and a preparation method thereof, and the preparation method thereof comprises the following steps: 1. Preparation steps; two. Homogenization process step; three. Tree ester modulation step; four. Iodine-polysaccharide complex resin filling step; Filter filling step; and six. Complete the steps.

The second filter body 23B is configured to filter at least one impurity 921 and the first filter body 23A. The third filter body 23C is configured to reduce the first filter body 23A. The structure in which the liquid 91 flows.

In practice, the iodine-polysaccharide mixture 21A is composed of an iodine-containing 211 (which may be 0.1 cc of iodine solution) and a polysaccharide 212 (0.15 gram of ball-milled polysaccharide powder).

The polysaccharide 212 can be one of starch, modified starch.

The pipe body 22 can be a straw having a large diameter (in principle, a diameter of 1 to 2 cm, which can be increased or decreased according to actual use requirements).

The iodine-containing granule 21B was first mixed with 9 sec of potassium iodide (KI) in 9 cc of deionized pure water (ddH ₂ O) and heated to 80 ° C. Further, 0.63 g of (solid) iodine (I ₂ ) and 2.5 cc of deionized pure water were mixed, and the mixture was stirred at 80 ° C, and the (solid) iodine was dissolved and the temperature was lowered to room temperature to obtain an iodide 211 (at this time). Appropriately liquid), and then mixed with deionized pure water (ddH ₂ O) soaked in the resin (experimental, preferably 3.8 grams), stirred for about 1 hour (or the solution is transparent) to get 15-25 % (w/w) of the iodine-containing granule 21B.

What is specifically stated here is that iodide has a disinfecting effect and has been used as one of the components of the filter core in the field of related drinking water.

Referring to Figure 17, there are three lines: the first curve L1 represents the measured result of the iodine-polysaccharide complex resin portion 21 of the present invention; the second curve L2 represents the measured result of the conventional iodine-containing resin particle (initial period) The iodine concentration is not high enough, and the disinfection effect is poor at this stage; the third curve L3 indicates the actual measurement result of no iodine in another conventional filter.

Among them, the third curve L3 is almost integrated with the time axis, indicating that the iodide is not released at all, which is for reference.

Referring to the seventh and eighth figures, since the present invention coats the iodine-polysaccharide mixture 21A on the outer surface of each of the iodine-containing resin particles 21B, when the liquid 91 flows through the plurality of iodine-containing granules 21B, A portion of the liquid 91 will flow from a plurality of the iodine-containing resin particles 21B (in principle, the iodine-polysaccharide mixture 21A which is coated with the iodine-polysaccharide mixture 21A is wetted), and a part thereof The liquid 91 is infiltrated into the iodine-polysaccharide mixture 21A and further re-infiltrated into the iodine-containing granule 21B. At this time, the iodine-polysaccharide mixture 21A immediately releases iodine 201, and the iodine-containing granule 21B is not immediately released. Iodine 201 (but rather slowly releases iodine 201 as shown by the second curve L2). In other words, since the present invention has the iodine-polysaccharide mixture 21A coated on the periphery, the iodine 201 can be quickly released. The iodine-polysaccharide complex resin portion 21 is increased from 0 to 0.18 to 0.2 (mg/L) at a stage of 0 to 0.1 (abbreviated value) minutes at the initial stage, that is, release of iodine 201. The fastest and highest concentration. After a period of time, the iodine-containing resin particles 21B also continuously release iodine 201 from the slit 21C, so that the release of iodine 201 is maintained at a high concentration for almost the entire period of time.

When the liquid 91 is in the tube body 22, flows from the water inlet end 222 toward the water outlet end 223, and then is used for drinking or drinking, the iodine-polysaccharide complex resin portion 21 and the first filter body 23A are flowed through (ie, The order of the activated carbon structure), the second filter body 23B (ie, the filter cotton structure) and the third filter body 23C (ie, the filter cloth structure), and the number of the foregoing filter structures are set. For the effect of water flow (which relates to the speed and fluency of water filtration or liquid absorption) and iodine concentration, the following table 1 shows:

As can be seen from Table 1, when the ratio of the resin to the activated carbon is 1.25 to 1, the amount of activated carbon is sufficient to remove the iodine residue, so the group 1 has no iodine residue. However, in Groups 3 and 4, when the same amount of material is placed in batches, more activated carbon will flow between the resins, affecting the flow rate and weakening its iodine removal efficiency, resulting in residual iodine, and Group 5 using filtration. In the case of cloth, although the flow rate was improved by 40%, the adsorption time and efficiency were reduced.

Therefore, in groups 6 and 7, we maintain stratification with filter cloth and reduce the proportion of resin used, thereby reducing the amount of iodine residues, and there is no residual iodine at a speed of 60-65. Therefore, the order and proportion of the resin and activated carbon can affect the liquid. The fluency, flow rate and residual iodine of the body 91.

Referring to Figure 18A (Fig. 19A is an actual photograph), it is an enlarged view of the filtered liquid 91 of the present invention, which shows that within five liters, the impurity-free liquid 91 can be filtered. The eighteenth B-picture (the nineteenth B-picture is its actual photo) shows the unfiltered dirty liquid 92 filled with impurities 921 for comparison.

The advantages and effects of the present invention can be summarized as follows:

[1] Water absorption exerts a bactericidal effect. The iodine-polysaccharide mixture of the present invention exerts an immediate bactericidal effect as long as it absorbs the liquid and immediately releases iodine, that is, the liquid is simultaneously sterilized into potable water during the passage of the tube of the present invention. Therefore, water absorption exerts a bactericidal effect.

[2] Sustainable release of iodide. The iodine-polysaccharide complex resin ester part of the invention consists of an iodine-polysaccharide mixture and iodine-containing granules, and the iodine-polysaccharide mixture immediately releases iodine upon absorption of water to immediately sterilize the liquid, and the iodine-containing granules are also released. Iodine (slightly slower, but lasting longer) can also sterilize liquids.

[3] The straw type structure is convenient to use. The present invention can be configured as a straw-type structure, and the user can simultaneously sterilize the liquid as it passes through the straw by using the straw to drink the liquid, allowing the user to drink the hygienic liquid. There is no need for additional filtration sterilization. Therefore, the straw type structure is convenient to use.

[4] Free of electricity for use in the wild. The invention mainly sterilizes liquid by iodine (known in the industry, the effect is clear), and the sterilization process does not require electricity at all. Therefore, the use of electricity is conducive to the use of the field.

[5] No residual iodine does not harm the human body. In the tube body, activated carbon is disposed between the iodine-polysaccharide complex resin ester portion and the water outlet end, so that the sterilized and filtered water liquid is filtered by the activated carbon to remove residual iodine before being sucked into the drinking water. There is no residual iodine in drinking water. Therefore, no residual iodine does not harm the human body.

[6] Improve traffic and fluency. In the tube body, between the iodine-polysaccharide composite resin portion and the inlet and outlet ends, a plurality of layers of filter cotton structure and filter cloth structure are respectively arranged, and the activated carbon particles can be fixed, so that the activated carbon particles do not follow the water liquid. (the large amount of water flowing through for drinking) flows, which can maintain the gap in the pipeline during drinking, which helps Improve flow rate and fluency. Therefore, the filter body purifies the water quality and increases the flow rate.

The present invention has been described in detail with reference to the preferred embodiments of the present invention, without departing from the spirit and scope of the invention.
