Process Description:

The untreated exhaust gas contains a small amount of water mist and particulate matter. If it enters the activated carbon adsorption system directly, it will block the voids of the activated carbon, resulting in reduced or even failed adsorption efficiency. At the same time, due to the long service life of the activated carbon (in the case of analytical equipment) In order to ensure the adsorption effect of activated carbon, the filter is usually used to remove dust and viscous material before the exhaust gas enters the activated carbon adsorption bed. The filter usually adopts two sections: the first section: filtration precision G3, the second section: filtration precision G4, ensuring The activated carbon waste gas is relatively clean.

The filter is used to capture the dust in the exhaust gas. If the dust directly enters the concentration adsorber, it will block the capillary pores of the adsorbent material and reduce the adsorption performance. The filter adopts the initial effect + bag type medium efficiency filtration, which will be designed for maintenance and easy to disassemble and install. The differential pressure switch represents the pressure loss in real time. According to the set pressure, an alarm signal is sent to the PLC when a certain pressure difference is exceeded, so that the user can replace the filter material in time.

After the honeycomb activated carbon is saturated, the saturated activated carbon bed is alternately switched with the activated carbon bed to be used after desorption according to the PLC automatic control program. The BCO automatically raises the temperature and sends the hot air to the activated carbon bed through the fan to warm the carbon layer to desorb the organic matter from the activated carbon. The desorbed exhaust gas belongs to the organic waste gas with high concentration, small air volume and high temperature.

The high-concentration, small-volume, high-temperature organic waste gas desorbed by activated carbon is filtered by a flame arrester, and then enters a special plate heat exchanger to exchange energy with the high-temperature gas after the catalytic reaction. At this time, the temperature of the exhaust gas source is obtained. The first lifting; the gas with a certain temperature enters the preheater for the second temperature increase; then enters the first-stage catalytic reaction, at which time the organic exhaust gas partially decomposes at low temperature and releases energy to the exhaust gas source. Direct heating is carried out to raise the temperature of the gas to the optimum temperature of the catalytic reaction; the temperature detection system meets the temperature requirement of the catalytic reaction, enters the catalytic combustion chamber, the organic gas is completely decomposed, and a large amount of heat is released; The gas is converted into thermal flow by the heat exchanger through a heat exchanger, and the gas is evacuated by the induced draft fan after the temperature is lowered.
