Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Thus, a feature indicated in this specification will serve to explain one of the features of one embodiment of the invention, and does not imply that every embodiment of the invention must have the stated feature. Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.
The principles of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in fig. 1, the method for manufacturing a chlorine dioxide slow-release material provided by the present invention requires a closed container containing an alkaline liquid, and the temperature in the closed container can change chlorine dioxide gas into liquid chlorine dioxide, i.e. the temperature in the closed container satisfies the temperature range for converting chlorine dioxide gas into liquid chlorine dioxide, and the temperature range is greater than 0 ℃ and less than or equal to 11 ℃.
Then injecting chlorine dioxide gas into the alkaline aqueous solution in the closed container to change the original alkaline aqueous solution into a mixed solution containing liquid chlorine dioxide, chlorine dioxide aqueous solution and alkaline aqueous solution, wherein the content of chlorine dioxide in the mixed solution is higher than that of the existing chlorine dioxide aqueous solution, which is beneficial to adsorbing more chlorine dioxide in the subsequent adsorption step, and the alkaline aqueous solution is low-concentration alkaline aqueous solution, and can generally adopt 1% -5% of sodium hydroxide aqueous solution with concentration of 3%, for example, or a mixture of sodium hydroxide and other alkaline substances.
And then putting a solid adsorption carrier into the mixed solution and absorbing and adsorbing the mixed solution, wherein in one embodiment, the solid adsorption carrier is a powdery or granular porous adsorption material, such as powdery activated carbon, silicon dioxide or nano ceramic material. In a preferred embodiment, an ultrasonic vibrator is installed in the closed container, and the mixed solution mixed with the solid adsorption carrier is vibrated by the ultrasonic vibrator for a preset time, so that the solid adsorption carrier fully absorbs the mixed solution, thereby further improving the adsorption rate of the solid adsorption carrier on chlorine dioxide.
And finally, filtering and drying the solid adsorption carrier absorbing the mixed solution to form the chlorine dioxide slow-release material. In one embodiment, the solid adsorption carrier absorbing the mixed solution is dried by dehumidifying at normal temperature, so that the cost is saved, and the influence on the product quality caused by other chemical reactions generated by high-temperature drying is avoided.
In a further preferred embodiment, chlorine dioxide is collected during the production process for reuse or for discharge to a safe place, for example, an outlet pipe may be provided on the closed vessel, a one-way outlet valve may be provided in the outlet pipe, and chlorine dioxide gas that is not liquefied or dissolved is collected through the outlet pipe and the one-way outlet valve when chlorine dioxide is injected into the alkaline aqueous solution. For another example, the volatile chlorine dioxide gas can be filtered and collected in the drying process at normal temperature.
In the chlorine dioxide slow release material formed by drying, chlorine dioxide is better fixed in a solid adsorption carrier by alkaline substances, and the reason is that the chlorine dioxide is acidic, the alkaline substances are alkaline and can play a certain locking role, and the volatilization of the chlorine dioxide in the drying process is greatly reduced, if diatomite is used as an adsorption material, the content of the chlorine dioxide can reach 1% -5%, and the chlorine dioxide has higher purity and does not contain other gas impurities. In addition, under the common condition, the chlorine dioxide in the chlorine dioxide slow-release material can be slowly released, but due to the locking effect of the alkaline substances, the slow-release amount of the gaseous chlorine dioxide is small, and the great reduction of the sterilization effect of the product is avoided. When encountering harmful irritant substances such as bacteria, formaldehyde and the like, the chlorine dioxide can be stimulated and promotes slow release due to chemical reaction, thereby playing better effects of sterilization, aldehyde removal and the like, and having a more lasting sterilization effect if being used on personal articles of human bodies, thereby enhancing the durability of products.
After the preparation of the chlorine dioxide slow-release material is finished, when the chlorine dioxide in the chlorine dioxide slow-release material is slowly released to enable the content of the chlorine dioxide in the chlorine dioxide material to be lower than the preset content, the material is changed into a chlorine dioxide supplement material, the chlorine dioxide supplement material can be placed in liquid chlorine dioxide or gaseous chlorine dioxide to adsorb the chlorine dioxide to form the chlorine dioxide slow-release material again, the durability of the product is further enhanced, and the requirements of health care and sterilization of people can be fully met. For example, the chlorine dioxide gas is supplemented by products such as a chlorine dioxide slow-release generator, the chlorine dioxide supplementing materials are placed together in a relatively closed small space such as a shoe cabinet, so that the small space is filled with chlorine dioxide gas with a certain concentration, and the chlorine dioxide supplementing materials adsorb a certain amount of chlorine dioxide gas to form chlorine dioxide slow-release materials after 1 to 10 hours or so, so that the chlorine dioxide slow-release materials can be supplemented repeatedly, and the function of long-term use is achieved.
Besides the above-mentioned materials, the fixed adsorption carrier of the present invention can also be one or a combination of two or more of materials such as silicon dioxide, diatomite, kaolin, bentonite, saponite, zeolite, medical stone, bamboo charcoal powder, quicklime, calcium carbonate, silica gel, ceramic balls, alumina, activated alumina, carbon fibers, molecular sieves, nanoceramics, or various composite materials of the above materials and textile materials.

In the process, the total amount of chlorine dioxide gas led into the closed reactor is controlled below a safety value, the content of chlorine dioxide in the mixed solution is not more than 2 percent, and the mixed solution meets the provisions of GBT 20783-2006.
In the production process, the air outlet pipe of the closed reactor is connected to the bottom of the liquid level of the sodium hydroxide solution in the chlorine dioxide gas recovery cabinet 6, so that the production safety is ensured. Meanwhile, the chlorine dioxide concentration of the solution in the chlorine dioxide gas recovery cabinet reaches a certain degree and then can be put into a closed reactor for recycling. 6% sodium hydroxide solution is placed in the chlorine dioxide gas recovery cabinet, the chlorine dioxide gas recovery cabinet is closed, an air outlet pipe is communicated with the outside of a hollow room, the safety guarantee effect of chlorine dioxide gas recovery is achieved, and a large amount of chlorine dioxide gas is absorbed and does not leak under the condition that equipment in the previous process is in fault.

Because the mixed solution of the invention contains liquid chlorine dioxide, the mixture of the liquid chlorine dioxide, the chlorine dioxide aqueous solution and the alkaline aqueous solution formed by entering the alkaline aqueous solution is not a pure chlorine dioxide aqueous solution, the chlorine dioxide content of the mixed solution is far higher than that of the chlorine dioxide aqueous solution, the solubility of the chlorine dioxide aqueous solution is below 2600PPM, and the invention has the following advantages: chlorine dioxide is relatively pure, has no negative effects, and is adsorbed more rapidly than aqueous solutions of chlorine dioxide and gaseous chlorine dioxide.
