Description

technical field [0001] The invention belongs to the technical field of waste gas treatment equipment, in particular to an organic waste gas treatment system. Background technique [0002] At present, the commonly used technologies for waste gas treatment include: UV photolysis and photocatalysis technology, activated carbon adsorption, RTO organic waste gas treatment and RCO organic waste gas treatment, etc. However, these technologies have some shortcomings: 1) UV photolysis and photocatalysis technology has low processing efficiency, and there are hidden dangers such as fire and explosion; 2) Activated carbon adsorption will cause secondary pollution and increase the cost of solid waste and hazardous waste treatment, and cause resource pollution. Waste; 3) The investment cost and operating cost of RTO and RCO organic waste gas treatment are high, and secondary pollution such as nitrogen oxides, carbon dioxide, and dioxins will also be generated. In short, the existing tec...

However, these technologies have some shortcomings: 1) UV photolysis and photocatalysis technology has low processing efficiency, and there are hidden dangers such as fire and explosion; 2) Activated carbon adsorption will cause secondary pollution and increase the cost of solid waste and hazardous waste treatment, and cause resource pollution. Waste; 3) The investment cost and operating cost of RTO and RCO organic waste gas treatment are high, and secondary pollution such as nitrogen oxides, carbon dioxide, and dioxins will also be produced

In short, the existing technology is generally treated without recycling, and the real environmental protection of recycling cannot be achieved.
