Description

Air purification system and method containing hydrophobic or/and hydrophilic volatile organic compounds

The invention relates to an air purification system and method comprising a hydrophobic or/and a hydrophilic volatile organic substance, in particular to a gas collection and a diversion according to the hydrophilicity or hydrophobicity of the volatile organic substance contained in the air to be purified, Designers who use both hydrophilic and hydrophobic processing equipment for purification.

According to the absorption method, the gas component has a different solubility in the liquid, and the gas component having the superior solubility in the gas mixture is transferred to a liquid. The absorption method can be a washing absorption method, a condensation absorption method or a condensation coagulation growth absorption. The most common absorption liquid in the washing and absorbing method is water or an aqueous solution containing high boiling water-soluble VOCs (for example, DMF). In principle, almost all volatile organic substances can be removed by washing in contaminated air, usually solubility. Preferred contaminants have better removal efficiency; however, the removal efficiency is determined by the different solubility between the gas components (hydrophilic (strong polarity) → high removal efficiency, hydrophobic (non-polar) → low removal efficiency), so contamination The gas-liquid equilibrium of the substance itself in the water, that is, the Henry's constant value of the pollutant in the water is a very important factor in the washing method; among them, according to the washing removal efficiency announced by the Environmental Protection Agency, the Henry's constant H (atm/(mol/m ³ ) )<5*10 ^-6 → Washing removal efficiency can reach 80%, 5*10 ^-6 <H<5*10 ^-5 → Washing removal efficiency is 50%, 5*10 ^-5 <H<10*10 ^-5 → Washing and removing The efficiency is 20%, 10*10 ^-5 <H→ washing removal efficiency is 10%.

Sub-press, some industries will produce hydrophobic or/and hydrophilic volatile organic compounds at the same time. For example, the printing industry and the coating industry use different organic solvents in different processes, and produce different components of volatility in different processes. Organic matter, such as a process that produces methanol-based volatile organic compounds, another process produces volatile organic compounds mixed with methanol and acetone, and another process produces toluene-based volatile organic compounds; however, due to different The Henry's constant H of volatile organic compounds is high or low. The removal efficiency of methanol (H is 0.00000278) can be more than 80%, while the removal efficiency for acetone (H is 0.000026) is 50%, but for toluene (H is 0.00683). The removal efficiency is only 10%; in addition, the adsorption material of the adsorption and desorption method is divided into a hydrophobic adsorption material and a hydrophilic adsorption material. If the zeolite is higher in terms of zeolite, it is hydrophobic, and the aluminum is hydrophobic. The lower one is more hydrophilic. Therefore, the removal efficiency of the hydrophobic adsorbent and the hydrophilic adsorbent is determined by the different polarities between the gas components (hydrophobic (non-polar) → hydrophobic). High removal efficiency of the material, hydrophilicity (strong polarity) → high removal efficiency of hydrophilic adsorption materials); therefore, it is difficult to purify air containing hydrophobic or/and hydrophilic volatile organic compounds only by simple washing method or single The adsorbent material is removed by adsorption and desorption.
