Organic waste gas purification system
The organic waste gas is first preheated through a high-temperature ceramic filling layer that has been "heat-storage". The heat-storage ceramic is made of a material with high thermal conductivity and has good heat exchange characteristics. The pre-heated organic waste gas is heated to about 250 ° C through the combustion chamber, and is rapidly oxidized and generates harmless CO2 and H2O under the action of the catalyst, while releasing a large amount of heat.
The oxidatively decomposed high-temperature exhaust gas enters the filling layer of the low-temperature heat storage body, and after transferring the heat energy to the heat storage body, it is discharged into the atmosphere through a switching valve, and its discharge temperature is only slightly higher than the temperature before the exhaust gas treatment.
The above process is automatically completed by a PLC-controlled switching valve, and all ceramic heat storage bodies complete the cycle steps of heat release and heat absorption, and the heat generated during the oxidation system reaction process can be fully utilized.
◆ Easy operation. When the equipment is working, realize automatic control;
◆ Low ignition temperature and low energy consumption.
◆ Safe and reliable. The safety settings are fully equipped, and the equipment is equipped with protection measures such as fire resistance system, explosion-proof pressure relief system, alarm device and automatic shutdown;
◆ Reuse of waste heat: the waste heat can be returned to the drying tunnel to reduce the power consumption in the original drying tunnel; it can also be used as a heat source in other aspects;
◆ Low resistance and high purification efficiency. Use high-quality precious metals, rare earths and metal oxides as catalysts on honeycomb ceramics;
◆ Long service life of catalyst;
◆ The reaction temperature is low, no secondary pollutants such as nitrogen oxides are generated, and all processes will not cause secondary pollution;
◆ The removal efficiency can reach more than 95%, and the heat recovery rate can reach more than 95%.
