What are the methods of acetone exhaust treatment

Acetone is also called dimethyl ketone, is a colourless bright liquid, very soluble in water and methanol, ethanol, ether, chloroform, pyridine and other organic solvents, in the industry is mainly used in the plastics, rubber, grease, spraying and other industries, acetone exhaust treatment is generally how to do it? Here with the Everest blue editor to see what methods of acetone exhaust treatment.

Water spraying purification method: It has significant treatment effect on industrial waste gas such as acid mist waste gas treatment, alkali mist waste gas treatment and paint waste gas treatment, spraying waste gas treatment, organic waste gas treatment of absorption and dissolution, chemical waste gas adsorption, oxidation reduction, acid and alkali neutralisation;
A brief acetone waste gas treatment plan

Condensation method: the use of acetone exhaust gas of different vapour pressures, through the pressure and temperature regulation so that acetone supersaturation and condensation effect occurs, so that the mixture of acetone air to a high degree of purification, acetone can also be recovered;

Absorption method: by selecting the lower volatility of the solvent as an absorbent, the use of acetone in the solvent solubility to achieve purification. Absorption method process is simple, the process is not chaotic, high purification power, is currently the more ideal acetone exhaust gas purification technology. Through the wet exhaust gas treatment equipment packing tower, the agent can be useful to deal with acetone exhaust gas, the process is simple;

Incineration method: divided into direct flame incineration and catalytic incineration. It uses direct oxidation and catalytic oxidation to differentiate and destroy the organic molecules in the exhaust gas, so that it is born with low-toxicity or harmless substances, so as to achieve the intention of direct emission of volatile organic compounds;

Adsorption method: recovery of industrial waste gas acetone is more commonly used in a waste gas purification methods, its process is sophisticated, has a high degree of efficiency. At present, the common adsorbents are activated carbon, silica gel substances. Wanchuan environmental protection activated carbon adsorption tower, purification power up to 95%, process sophistication, is a common approach.

For acetone waste gas treatment is mainly used RTO regenerative thermal incineration method, the process is the organic waste gas pre-treated, heated to a temperature of 760 ℃ above the temperature of the organic waste gas oxidation and decomposition of the waste gas into carbon dioxide and water. After heating the high-temperature gas flow through the special ceramic heat storage body, the ceramic body will be warming "heat storage", the stored heat will be used to preheat the new organic waste gas. This saves fuel consumption for the heating of the exhaust gases and allows for a steady evolution of the treatment cycle.
