Method for improving treatment efficiency of organic waste gas by adopting four-bed RTO and four-bed RTO

Abstract

The invention discloses a method for improving the treatment efficiency of organic waste gas by adopting a four-bed RTO and the four-bed RTO, and belongs to the technical field of organic waste gas purification treatment. According to the method, only one heat storage chamber needs to be added on the basis of an original three-bed RTO, the overall treatment and purification efficiency is higher after storage chambers of the four-bed RTO are adopted, secondary pollution such as ammonium salt solid waste and ammonia nitrogen-containing wastewater cannot be generated, and the blockage of substances such as various ammonium chloride, ammonium sulfite, ammonium sulfate and triethylamine hydrochloride on a heat storage ceramic body can be effectively prevented, and thus the stability and safetyof an ammonia-containing, amine-containing, chlorine-containing and sulfur-containing exhaust gas treatment system are further improved. According to the heat storage chambers of the four-bed RTO, themethod that the wind reverse blowing and then sweeping are carried out and the exhaust gas combustion is performed is adopted, so that the temperature of the bottom of the heat storage chambers is effectively reduced, the heat loss is less, the thermal efficiency is higher, and the RTO system is more energy-saving.

Description

technical field [0001] The invention belongs to the technical field of organic waste gas purification and treatment, and in particular relates to a method for improving the treatment efficiency of organic waste gas by adopting a four-bed RTO and the four-bed RTO. Background technique [0002] Regenerative thermal incinerator (RTO) is an efficient organic waste gas treatment equipment. Its working principle is to heat organic waste gas to 760-850 °C, and oxidize and decompose volatile organic compounds (VOCs) in the waste gas into carbon dioxide and water. [0003] The heat generated by the oxidation process is stored in a special ceramic regenerator, which makes the regenerator heat up and "storage". The heat stored in the ceramic regenerator is used to preheat the organic waste gas that enters later. This process is the "heat release" process of the ceramic regenerator, thereby saving fuel consumption in the process of heating up the exhaust gas. In foreign countries, two-...
