Description of the invention: [Technical field to which the invention pertains] The present invention relates to an organic exhaust gas purification system and method for preventing condensation and agglomeration on the surface of an adsorbent material, in particular, adding an adsorption before the desorption procedure is performed. The designer of the preheating or/and preheating process to preheat the organic waste gas. [Prior Art] According to the adsorption and purification technology of volatile organic gases (Vo丨at i丨e 〇rgan icc〇rap〇unds, VOCs) by high-porosity, high specific surface area adsorption materials, such as The fluidized floating bed purification system shown in the first figure is a common organic waste gas purification system, which is sent from the organic waste gas inlet (13) to the bottom of the adsorption tower by the exhaust gas fan (14) and the organic exhaust gas is dispersed by the gas flow. After the plate (12) is dispersed, it is contacted with the adsorbing material (30) dropped from above, and can be purified gas and discharged from the purification gas outlet (15) at the top of the column; wherein the inside of the adsorption tower (10) is a perforated plate (11) Separated into several layers, the adsorbent material (30) is dropped from the tip end of the adsorption tower (1〇), and a floating layer ' is formed above the perforated plate crucible 1) and falls down along the open side of the perforated plate (11) When the adsorbent material (30) is in contact with the organic exhaust gas, the organic gas in the exhaust gas is adsorbed into the pores of the adsorbent material (30), and the exhaust gas becomes a purge gas discharge; however, the adsorbed saturated adsorbent material (3〇) Fall to the adsorption tower (1〇) After the tank (16) portion, by conveying means (20) is sent to the subsequent desorption column (4〇) top end 'desorption regeneration operation back to the adsorption column (1〇) of the top. Then, the adsorbent material (30) to be regenerated is slowly flowed down in the desorption column (40).
