Description
Technical Field
The invention relates to the technical field of air purification, in particular to an alkaline electrolyte air purification filter material and a preparation method thereof.
Background
The air carrying chemical pollutants has very complex components, including thousands of chemical substances, wherein the main harmful to health is acidic air carrying chemical substances, alkaline air carrying chemical substances, activity and odor of VOCs, and the inorganic pollutants and organic pollutants can directly enter and adhere to respiratory tracts or alveoli of human bodies to easily cause acute or chronic respiratory diseases, such as asthma, bronchitis, emphysema, sphagitis, cancers and the like.
Wherein, the acidic air carrying chemical pollutants mainly comprises: chlorine, hydrogen sulfide, nitrogen oxides, hydrogen chloride, sulfur dioxide, organic acids, and other acidic corrosive gases. The active classes of VOCs mainly include: aldehydes, phenols, ketones, olefins, enols, terpenes, acetates, alcohol ethers and the like. Other classes of VOCs include: other VOCs macromolecules or non-active substances such as aliphatic hydrocarbons and aromatic hydrocarbons.
In the field of air purification, various methods exist in the market for removing chemical pollutants carried in air. The technology has various kinds, but the defects of single function and poor removal effect generally exist. The main performance is as follows:
most air purification technologies adopt activated carbon adsorption, but the activated carbon adsorption is greatly influenced by the relative humidity of air, and is easy to desorb under the condition of saturation, so that secondary pollution of chemical substances is caused. The active carbon has higher adsorption capacity to VOCs macromolecules, and part of the active carbon adsorption capacity can reach 20% according to specific gravity, but carries chemicals to micromolecular air, the effect of the active carbon adsorption efficiency or the adsorption capacity is deficient, the effect can be achieved by additionally using a large amount of active carbon, and the airflow resistance of the air purification equipment can be increased by using a large amount of active carbon. The activated carbon belongs to solid waste supervision in environmental protection application of tail gas and waste gas, the waste activated carbon has the characteristics of leaching out toxic, corrosive, flammable and reactive hazardous wastes, if the waste activated carbon is not treated, direct landfill can cause great harm to soil and underground water sources, and the activated carbon used in certain areas can be recycled after being chemically treated and reaching the standard after neutralization.
Other existing air purification techniques include UV photolysis oxidation, low temperature plasma ESP, combustion and biological methods to remove airborne chemical pollution. The UV photolysis oxidation method has the problems that the filtering efficiency is influenced by humidity, and when the relative air humidity RH is more than 70 percent, the UV photolysis effect is obviously reduced; and UV photolysis needs to be matched with catalytic oxidation reaction to remove small molecular air carried chemicals, and the problems of high operation cost, fast catalyst attenuation and frequent replacement are also existed. The removal rate of the low-temperature plasma ESP technology cannot reach a set value generally, and most equipment is deodorized by ozone generated by a high-voltage electric field, so that secondary pollution of the ozone is easily generated; when VOCs are removed, the plasma arc has a potential explosion hazard. The combustion method removes gas-carried chemical pollution, and the shortcoming discharges waste gas during the burning, and temperature control improper produces secondary pollution easily during the burning, and the result after the burning is solid danger useless, belongs to the solid useless supervision of environmental protection. The biological method technology has large occupied area and high requirement on operation management, and needs dust removal and temperature, humidity and PH value control; and the strain needs environmental adaptation and time for culture, the growth of the strain is easily inhibited by complex chemical gas, and the strain is damaged by gas concentration.
The chemical impregnation method is a commonly used filtering technique of chemical adsorption method, and various base materials are impregnated by a solution containing active substances, so that active soluble compounds are solidified on the surface of a carrier. Impregnation methods, while simple and inexpensive to manufacture, often suffer from a number of complex problems. Such as the active substance moving to the outer surface and causing the concentration of the active substance at the inner surface to decrease, even if the carrier is not covered. Chemical impregnation methods are generally relatively simple in effect, contain relatively isolated active substances, and the substances lack systematic and effective classification in chemical and physical properties, such as solubility, moisture absorption, ionization capacity, hydrolysis capacity, dispersibility, electronic effect, steric effect, chemical reaction capacity, chemical kinetics and the like, which are factors directly influencing the chemical impregnation effect. The above factors make the combination of chemical impregnation relatively isolated, lacking systematic combination, with both advantages and disadvantages in practical applications. Secondly, the traditional chemical immersion method is easy to generate waste water and waste gas in the production process, thereby causing secondary chemical pollution.
It is seen that improvements and enhancements to the prior art are needed.

Detailed Description
The invention provides an alkaline electrolyte air purification filter material and a preparation method thereof, and the invention is further described in detail by the following examples in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
The invention provides an alkaline electrolyte air purification filter material, which comprises 13-23 parts by weight of strong base electrolyte components and/or weak base electrolyte components, 30-45 parts by weight of filter material, 1-6 parts by weight of surfactant, 0.5-2 parts by weight of thickener and 35-45 parts by weight of water; the strong base electrolyte component is at least one of a strong base component, a strong base weak acid salt component and an alkaline oxide component; the weak base electrolyte is a weak base.
Specifically, the filter material is used for loading alkaline electrolyte components (strong base electrolyte components and/or weak base electrolyte components) in a pore structure on the surface or inside the pore structure. The thickener within the above range is used to crosslink with the alkaline electrolyte component, so that the alkaline electrolyte component is stably loaded in the pore channel of the filter material to form a stable three-dimensional structure. The surfactant within the above range serves to increase the solubility of the alkaline electrolyte component, so that the alkaline electrolyte component is rapidly and largely adsorbed by the porous structure of the filter material. The water plays a role in adjusting the solid content in the system and prevents the alkaline electrolyte components from being too weak to influence the chemical reaction with the acidic air carrying chemical substances and the VOCs active chemical substances.
Specifically, after the purification filter material adsorbs the acidic gas and the active chemical substances of VOCs by utilizing the porous structure of the filter material, the double decomposition reaction between the alkaline electrolyte and the chemical substances carried by the acidic air occurs, namely, at least one of the strong base component, the strong base and weak acid salt component and the alkaline oxide and the acidic gas generate chemical neutralization reaction. The alkaline electrolyte and the carbon-hydrogen bond and the carbon-oxygen bond of the active chemical substances of the VOCs are subjected to redox reaction, the carbon-hydrogen bond of the VOCs can be subjected to hydrogen atom removal to generate water through complete redox reaction, the carbon-oxygen bond of the VOCs can be subjected to oxygen atom generation to generate carbon dioxide, and partial redox reaction and generation of intermediate products are accompanied in most cases. More specifically, the strong base and weak acid salt component is an amphoteric substance which can react with both acid gas and alkaline gas, that is, the purification filter material loaded with the strong base and weak acid salt component can decompose acidic air pollutants and VOCs active pollutants, can also decompose part of alkaline air pollutants, and has the advantages of chemical absorption, chemical neutralization and redox decomposition of pollutants of the purification filter material.
In this embodiment, the strong base component includes NaOH, KOH, ba (OH) 2 、Ca(OH) 2 At least one of (1). The strong base refers to the substance with all ionized anions in the water solution as hydroxide ions, and the alkalinity of the strong base components is sequentially KOH & gt Ca (OH) 2 ＞NaOH＞Ba(OH) 2 .

The strong base weak acid salt is a salt generated by the reaction of strong base and weak acid, acid radical ions or non-metal ions consume part of hydrogen ions in hydrolysis to ionize hydroxide ions, and most of strong base weak acid salt solutions are alkaline.
In this embodiment, the basic oxide component includes Na 2 O、K 2 O、MnO 2 At least one of CaO and MgO. Basic oxides are compounds which dissolve in water and form only a base or a salt formed by reaction with an acid and water. When the above-mentioned alkaline oxide is dissolved in water, the correspondent hydrates are all alkaline, for example, the hydrate of sodium oxide is sodium hydroxide, the hydrate of potassium oxide is potassium hydroxide, the hydrate of manganese oxide is manganese hydroxide, the hydrate of calcium oxide is calcium hydroxide, and the hydrate of magnesium oxide is magnesium hydroxide. The above-mentioned alkaline oxide hydrate has a large difference in alkalinity, and when the hydrate is a strong alkali component, attention should be paid to the amount of addition in the preparation of the purification filter material.

The weak base refers to a base which is not completely ionized after being dissolved in water, and compared with the strong base, the weak base has a poor capability of receiving protons from water molecules, so that the concentration of hydrogen ions in the solution is higher, and the pH value of the solution is lower.
The alkaline electrolyte component is divided into a strong alkali component, a strong alkali weak acid salt component, an alkaline oxide component and weak alkali according to the alkalinity of a hydrate after hydrolysis, chemical elements of the multi-component alkaline electrolyte component are classified and compiled, the chemical elements of the purification filter material are classified corresponding to active substance combinations, the active substance combinations are classified corresponding to air-borne chemical pollutants, the air-borne chemical pollutants are efficiently fixed and removed through chemical absorption, chemical neutralization and redox methods, and harmful pollutants are converted into harmless reaction end products.

And step four, drying the filter material in an oven at the temperature of 140-180 ℃.
