Is it necessary to install a quench tower?
Thread Content
The incineration of hazardous waste requires a quench tower, whose function is to reduce the temperature of the flue gases from around 500°C to around 200°C in a short time, in order to prevent the reformation of dioxins. This approach is very unfavorable for energy utilization. Has anyone studied the extent to which quenching or the lack thereof affects the reformation of dioxins? Theoretical discussions are also welcome.
Is the amount of smoke large? What about adding a waste heat boiler? If rapid cooling is to be used, water spraying is the only option; however, the amount of water used is too large, which makes it difficult to handle the smoke and also hinders anti-corrosion measures
The cooling time must be within 1 second; spray cooling is required to achieve this, as exceeding this time will result in a sharp increase in dioxin levels.
Our company also has a quench tower behind the waste heat boiler; the temperature at which dioxins are generated is between 200 and 500 degrees, so it is necessary to rapidly reduce the temperature below 200 degrees. Indeed, some of this energy is lost in this process
Setting aside energy loss and dioxin regeneration, if it is built as a hazardous waste facility, **there are regulations requiring the installation of a quenching system.**
