含有有機物的廢氣在風機的作用下通過活性炭吸附層,有機物被活性炭獨特的作用力攔截,清潔氣體排出;一段時間后,當活性炭達到飽和時,吸附停止,有機物已經(jīng)濃縮在活性炭中。
The exhaust gas containing organic matter passes through the activated carbon adsorption layer under the action of the fan, and the organic matter is intercepted by the unique force of the activated carbon, resulting in the discharge of clean gas; After a period of time, when the activated carbon reaches saturation, adsorption stops and the organic matter has been concentrated in the activated carbon.
催化凈化裝置內設有加熱室,加熱裝置開始進入內循環(huán)。當熱脫附氣體進入活性炭箱,活性炭層溫度上升到有機物沸點時,有機物從活性炭中跑出,進入催化室催化分解成CO2和H2O,同時釋放能量。釋放的能量用于進入吸附床進行脫附。此時,加熱裝置完全停止工作,有機廢氣在催化燃燒室中保持自燃,尾氣再生循環(huán),直至有機物與活性炭完全分離并在催化室中分解。活性炭再生,有機物催化分解處理。
The catalytic purification device is equipped with a heating chamber, and the heating device begins to enter the internal circulation. When the thermal desorption gas enters the activated carbon box and the temperature of the activated carbon layer rises to the boiling point of the organic matter, the organic matter escapes from the activated carbon and enters the catalytic chamber for catalytic decomposition into CO2 and H2O, while releasing energy. The released energy is used to enter the adsorption bed for desorption. At this point, the heating device completely stops working, and the organic waste gas maintains spontaneous combustion in the catalytic combustion chamber. The exhaust gas is regenerated and circulated until the organic matter is completely separated from the activated carbon and decomposed in the catalytic chamber. Activated carbon regeneration, organic matter catalytic decomposition treatment.

The gas reaches the combustion reaction temperature through a heating device, and then the organic gas is decomposed into carbon dioxide and water through a catalytic bed. It enters a heat exchanger for heat exchange with the low-temperature gas, causing the temperature of the incoming gas to rise to the reaction temperature. If the reaction temperature is not reached, the heating system can compensate for heating through an automatic control system, allowing it to burn completely, thereby saving energy. The effective removal rate of exhaust gas reaches over 97%, which meets national emission standards. The device consists of a host, an induced draft fan, and an electrical control cabinet. The main unit of the purification device consists of a heat exchanger, catalytic bed, electric heating element, flame arrester, dust collector, and pressure reducing device. The flame arrester and dust collector are located on the intake pipeline, and the pressure relief device is located on the top of the main engine.
