Abstract
The invention provides waterborne VOCs absorption liquid and a preparation method thereof. The absorption liquid is prepared from, by weight, 3%-6% of nonionic surfactant and anionic surfactant, 1%-5% of FSO100 fluorocarbon surfactant, 1%-5% of FSN100 fluorocarbon surfactant, 1%-3% of emulsifier, 5%-10% of oilstone ester mineral oil and the balance water. By means of the absorption liquid, the emulsification effect of water and oil is enhanced, the solubility of methylbenzene is improved, the absorption amount of VOCs absorption liquid in industrial waste gas is greatly increased, the absorption efficiency of the VOCs absorption liquid in the industrial waste gas is greatly improved, the saturated absorption amount of VOCs is larger than or equal to 20 kg/t, and the absorption rate of VOCs is larger than or equal to 70%; the absorption liquid obtained after adsorption can be layered through still standing, an oil phase and a water phase are separated, and the oil phase and the water phase are recycled; the waterborne VOCs absorption liquid is not flammable and low in volatilization amount, safety is improved, the liquid viscosity is reduced, the dispersion effect generated when VOCs is absorbed is improved, and the absorption rate is increased; the oil content is low, the absorption liquid can be reused, the operating cost is low, the absorption efficiency and the saturated adsorption amount reached by a pure solvent absorption method can be achieved, and the gap of domestic absorption liquid products at present is filled in.
Description
technical field [0001] The invention relates to the field of environmental technology, in particular to a water-based VOCs absorbing liquid and a preparation method thereof. Background technique [0002] Volatile organic compounds are often expressed as VOCs. It is the abbreviation of the first letter of the three words Volatile Organic Compounds. Total volatile organic compounds are sometimes expressed by TVOC. [0003] Organic waste gas emitted by industry is one of the important sources of air pollution, and its impact on human living environment and human health has attracted increasing attention. At present, with the rapid development of industries such as electronics, machinery, automobiles, coatings, printing, and home improvement, the emissions of volatile organic compounds (VOCs) from raw material input to product output during the product manufacturing process are gradually increasing. As one of the main components of VOCs, the amount of benzene, toluene, formalde...
