Description

An improved regenerative thermal incinerator

technical field

The utility model is an improved regenerative thermal incinerator, which belongs to the field of thermal incinerators.

Background technique

The main RTO companies in China are: Aisel, Yongjiang Technology and other famous companies. The principle is to heat the organic waste gas to above 760 degrees Celsius, so that the VOC in the waste gas can be oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a special ceramic regenerator, which makes the ceramic body heat up and "reserve heat", which is used to preheat the organic waste gas that enters later. This saves fuel consumption due to exhaust gas heating up. The ceramic regenerator should be divided into two (including two) or more areas or chambers, and each regenerator undergoes the procedures of heat storage-radiation-cleaning in turn, repeating and working continuously. Immediately after the regenerator “releases heat”, part of the treated and qualified clean exhaust gas should be introduced to clean the regenerator (to ensure that the VOC removal rate is above 95%), and the “heat storage” program can only be entered after the cleaning is completed. .

The prior art discloses an improved regenerative thermal incinerator with the application number of 201420806855.9, which relates to a treatment equipment for organic waste gas. The equipment is controlled by PLC program, with high degree of automation and safe and reliable performance. The organic waste gas is heated to about 760-800°C, and the organic waste gas is oxidized and decomposed into harmless CO2 and H2O; the heat of the high-temperature gas during oxidation is absorbed by the heat storage body. Store it to preheat the newly incoming organic waste gas, thereby saving the fuel consumption required for heating, reducing operating costs, high purification efficiency, and no secondary pollution. In the existing technology, some waste gas residues are inevitable when the waste gas is burned Uneven combustion, mixed with carbon dioxide to discharge air, easy to pollute the environment.
