Tower type regenerative incinerator

Product Details

Tower type thermal storage incinerators, also known as tower type RTOs, are mainly divided into two bed, three bed, and multi bed types. The basic principle of tower type RTOs is that the organic waste gas to be treated is preheated in the thermal storage chamber A by the induced draft fan, and then enters the oxidation chamber, where it is heated and decomposed into carbon dioxide and water; The purified high-temperature exhaust gas leaves the oxidation chamber and enters the heat storage chamber B to release heat; C bed is used to blow and clean the thermal storage body. After completing one cycle, the intake, exhaust, and purge valves are switched once to change the direction of airflow, and the system enters the next cycle. The process continuously cycles and alternates, effectively reducing the heat emissions after exhaust gas treatment, while saving the heat loss during the oxidation and heating of exhaust gas. This ensures that the exhaust gas maintains a high thermal efficiency (about 95%) during the high-temperature oxidation process. The equipment is safe, reliable, easy to operate, maintain, and has low operating costs. The VOCs purification efficiency is as high as 99.5%. Tower RTO is an efficient organic waste gas treatment equipment developed and designed by our company based on the integration of domestic and foreign multi bed RTOs.

The organic waste gas to be treated enters the ceramic medium layer of the heat storage chamber 1 (which "stores" the heat from the previous cycle). The ceramic releases heat and the temperature decreases, while the organic waste gas absorbs heat and the temperature increases. After leaving the heat storage chamber, the waste gas enters the oxidation chamber at a higher temperature. At this time, the temperature of the waste gas depends on the volume of the ceramic body, the flow rate of the waste gas, and the geometric structure of the ceramic body.
In the oxidation chamber, the organic waste gas is heated by the burner to the set oxidation temperature of 760 ℃, causing the VOC components to decompose into carbon dioxide and water. Due to the preheating of exhaust gas in the heat storage chamber, fuel consumption is greatly reduced. The oxidation chamber has two functions: one is to ensure that the exhaust gas can reach the set oxidation temperature, and the other is to ensure sufficient residence time for the VOCs in the exhaust gas to be fully oxidized. The exhaust gas is incinerated in the oxidation chamber and becomes purified high-temperature gas before leaving the oxidation chamber and entering the heat storage chamber 2 (which has been cooled in the previous cycle). After releasing heat and cooling down, it is discharged, while the heat storage chamber 2 absorbs a large amount of heat and heats up (used to heat the exhaust gas in the next cycle). The purified exhaust gas is discharged into the atmosphere through the chimney, while a small stream of purified gas is introduced to clean the heat storage chamber 3. The exhaust temperature is about 40 ℃ higher than the intake temperature.
After the cycle is completed, the intake and exhaust valves are switched once to enter the next cycle. The exhaust gas enters from the heat storage chamber 2 and is discharged from the heat storage chamber 3. Simultaneously introducing a portion of purified gas to clean the heat storage chamber 1. Repeat the cycle and work continuously.

Technical principle:

Organic waste gas is collected through a waste gas collection device, and VOCs waste gas is sent to the RTO system through a high-pressure fan for heating. After the temperature is raised, it undergoes high-temperature oxidation and decomposition, forming non-toxic and odorless high-temperature flue gas. This device recovers and stores the heat energy from the high-temperature flue gas after combustion using a honeycomb ceramic thermal storage body, with a heat recovery rate of over 95%, which is used for preheating exhaust gas and achieving the goal of environmental protection and energy conservation.
