Overview

RTO (Regenerative Thermal Oxidizer, referred to as RTO), regenerative thermal oxidizer, is a kind of efficient organic waste gas treatment equipment. The principle is to oxidize the combustible waste gas into the corresponding oxide and water at high temperature, so as to purify the waste gas, and recover the heat released when the waste gas is decomposed, the waste gas decomposition efficiency reaches more than 99%, and the heat recovery efficiency reaches more than 95%. The main structure of RTO is composed of combustion chamber, ceramic packing bed and switching valve. According to the actual needs of customers, choose different heat recovery methods and switching valve methods.

The regenerative incinerator uses thermal oxidation method to treat the low and medium concentration of organic waste gas, and uses ceramic regenerative bed heat exchanger to recover heat. It is composed of ceramic heat storage bed, automatic control valve, combustion chamber and control system. Its main features are as follows: the automatic control valve at the bottom of the regenerator bed is connected to the intake manifold and the exhaust manifold respectively, and the regenerator bed is alternately reversed through the reversing valve to retain the heat of the high temperature gas coming out of the combustion chamber and preheat the organic waste gas entering the regenerator bed; Ceramic heat storage material is used to absorb and release heat; The organic waste gas preheated to a certain temperature (≥ 760℃) is oxidized in the combustion chamber to generate carbon dioxide and water, and is purified.

The typical two-bed RTO main structure consists of a combustion chamber, two ceramic packing beds and four switching valves. The regenerative ceramic filled bed heat exchanger in the device can recover the heat energy to the maximum extent, and the heat recovery rate is greater than 95%. VOC is handled with little or no fuel.

Applicable to the following organic waste gas treatment

1, applicable organic waste gas types: paraffin, olefins, alcohols, ketones, ethers, esters, aromatics, benzene and other hydrocarbon organic waste gas;

2, low concentration of organic matter (while meeting less than 25%LFL), large air volume;

3, the waste gas contains a variety of organic components, or organic components often change;

4, containing waste gas that is easy to poison the catalyst or decline the activity of ingredients.
