An activated carbon adsorption and desorption device (10) processes the adsorption, concentration and desorption of the VOCs exhaust gas, and then purifies or recovers the concentrated VOCs by a purification device (20). The adsorption performance of the secondary activated carbon is as shown in the second figure. Its adsorption capacity for V〇Cs is opposite to that of water absorption. When the relative humidity is low, the adsorption capacity for v〇Cs is high and the water absorption capacity is poor. When the water absorption capacity is high and the adsorption capacity for VOCs is poor, and the adsorption performance thereof is rapidly changed in the transition range of relative humidity 5〇~6〇% RH; therefore, the conventional ambient temperature organic solvent purification device enters the exhaust gas stream. When the activated carbon adsorption and desorption device (1 〇) is changed, the relative humidity of the exhaust gas stream is easily affected by the weather, so that the ability of the activated carbon adsorption and desorption device (10) to adsorb VOCs is unstable. That is, the overall purification effect is unstable. -3- M397284 [New Content] The main purpose of this creation is to solve the problem that the prior art is susceptible to weather and the effect of purification is unstable, and the effect of purification is stable and unaffected by the weather.

Further, the heat exchanger further adjusts the temperature rise by a controller, and the controller adjusts the temperature rise of the heat exchanger according to the relative humidity (or dew point temperature) of the exhaust gas to be purified. Further, the heat exchanger causes the relative humidity of the exhaust gas to be purified introduced into the activated carbon absorption and desorption device to be maintained below 6〇% RH. Further, the activated carbon adsorption and desorption device is an activated carbon fluidized concentrator or a fixed bed concentrator. Further, the purification device is an incinerator, a condenser, a spray chamber or a spray plus ozone chamber. [Embodiment] First, as shown in the second figure, the present invention introduces an exhaust gas containing an organic solvent generated in a normal temperature process zone into an activated carbon adsorption and desorption device (10) to treat the organic matter in the exhaust gas.

In addition, the heat exchanger (30) further adjusts the degree of temperature rise by a controller (31), and the controller (31) adjusts the heat exchanger according to the temperature and relative humidity (or dew point temperature) of the exhaust gas to be purified ( 3 〇) The degree of temperature rise is such that the relative humidity of the exhaust gas to be purified introduced into the activated carbon adsorption and desorption device (10) is maintained below 60% RH. Based on the composition, the creation of the waste gas to be purified containing organic solvent generated in the normal temperature process zone is moderately heated by a heat exchanger (usually not exceeding 45. 〇, 俾, the relative humidity is maintained at 6 〇%RH below' Let the activated carbon adsorption and desorption device (1 〇) carry out the adsorption process in an environment with better adsorption capacity of activated carbon, which will not be affected by weather and cause unstable purification effect, so it has stable purification effect.
