An exhaust gas treatment device combined with electrostatic degreasing and RTO（Patent No：ZL 2017 2 0685207.X）

This patent discloses an exhaust gas treatment device using electrostatic degreasing and RTO, which belongs to the field of environmental protection equipment. The exhaust gas treatment device for the combination of electrostatic degreasing and RTO is an exhaust gas discharge port connected to the air inlet of the electrostatic degreasing device, and the discharge port of the electrostatic degreasing device is connected to the intake pipe. And under the traction of the main fan, it is divided into three ways respectively to access the air inlets on the first regenerative chamber, the second regenerative chamber, and the third regenerator. The air outlets on the first regenerative chamber, the second regenerative chamber and the third regenerator are respectively connected to the exhaust pipe through a pipeline. The scavenging gas source is connected to the RTO incineration equipment's scavenging gas inlet through three pipelines. RTO incineration equipment has control valves at each inlet, outlet and sweep gas inlet. The utility model divides the treatment process containing exhaust gas into two parts: electrostatic degreasing and regenerative incineration. Through the organic cooperation of various parts, the efficient treatment and recycling of oil-containing waste gas are realized.

An exhaust gas treatment device for alternating adsorption desorption and RTO（Patent No：ZL 2016 2 1119709.4）

The patent discloses an exhaust gas treatment device for alternating adsorption desorption and RTO, which belongs to the field of exhaust gas treatment equipment. The first exhaust gas inlet of the device is sequentially connected to the filter, the RTO incineration device and the first fan through a pipeline, and the first fan outlet is connected to the exhaust gas discharge outlet; The pipeline after the second exhaust gas inlet is divided into two paths, and one passage passes through the first valve and communicates with the first exhaust gas inlet. The other way is connected to the air inlet of the adsorption desorption device through the second valve, and the air outlet of the adsorption desorption device is connected to the exhaust gas discharge outlet through the second fan; The high temperature gas outlet of the RTO incineration device is connected to the adsorption and desorption device to desorb the hot air inlet through the fourth valve. The adsorption desorption device desorbs the exhaust gas outlet through the fifth valve and the third fan and then communicates the pipeline between the filter and the RTO incineration device. The utility model can maintain the treatment of the exhaust gas of the plant at a low cost at night, and has good economy and reliability.
