Description

TECHNICAL FIELD [0001] The present invention relates to an apparatus for concentrating volatile organic compounds (GAS)

The present invention relates to an apparatus for concentrating a volatile organic compound gas having a stacked filter.

Volatile Organic Compound (VOC) refers to a liquid or gaseous organic compound that is easily vaporized into the atmosphere because of its high vapor pressure. Organic solvents are used in various industrial fields such as LCD and semiconductor manufacturing, painting, and production of petrochemical products, from which various VOCs are produced. VOCs often have odor and toxicity, and they are also precursors to photochemical oxides that cause global warming and destruction of the ozone layer. As a result, policy and technological efforts are being made to minimize the emission of volatile organic compounds and to preserve the environment in each country and most industrial sectors.

Treatment of malodorous or volatile organic compounds depends on the kind, concentration or amount of gas, and techniques such as incineration by heat, adsorption, absorption, condensation, biofiltration, catalytic oxidation, and photocatalytic oxidation are used. The double adsorption method has a high facility cost, has process flexibility, can be mass-processed, and can be applied to low-concentration pollutants. In the case of the adsorption type, the organic compounds adsorbed on the filter are accumulated over time and the purification efficiency of the filter is lowered. Therefore, an apparatus for separating and concentrating the organic compounds from the filter and regenerating the filter is indispensable. A rotor type in which a heated gas is supplied to a section of a disk-shaped filter to be rotated to separate an adsorbed organic compound is most commonly used in accordance with a regeneration method. Recently, a filter is configured in the form of a rotating cylinder, And a method in which the filter is regenerated by supplying a high temperature gas from the inside to the outside of the filter in some rotation sections has been proposed.

However, when the filter is rotated, the filter has to have a circular or cylindrical shape, which inevitably creates an insoluble space in which the filter is not mounted, which lowers the efficiency of the filtration process as a whole and has a complicated structure of the apparatus.

SUMMARY OF THE INVENTION An object of the present invention is to provide a volatile organic compound gas concentration apparatus having a stacked filter which is excellent in purifying efficiency of a gas containing VOC and can reduce the energy cost for operation.
