The main components of an incinerator scrubber system include:
1.Spray Tower or Contact Chamber: This is the primary section where the flue gas is brought into contact with the scrubbing liquid. The liquid is usually sprayed into the tower, creating a large surface area for gas-liquid interaction.
2.Scrubbing Liquid: Chemical solution is used as the scrubbing medium. Chemical solutions can be chosen based on the specific pollutants being targeted. For example, sodium hydroxide (NaOH) or lime (CaO) can be used to remove acidic gases like sulfur dioxide.
3.Gas-Liquid Contact: The pollutant-laden flue gas comes into contact with the scrubbing liquid. The pollutants are absorbed into the liquid through chemical reactions or physical absorption.
4.Separator: After the gas has been scrubbed, it passes through a separator or demister to remove any entrained droplets of the scrubbing liquid.
5.Treatment and Disposal: The captured pollutants are then typically treated and neutralized, and the resulting waste or byproducts are disposed of in accordance with environmental regulations.
Incinerator scrubbers are an essential part of waste-to-energy facilities and industrial incinerators because they help reduce the emission of harmful pollutants into the atmosphere, making the incineration process more environmentally friendly and compliant with air quality standards. The specific design and operation of incinerator scrubbers can vary depending on the type of waste being incinerated and the pollutants of concern.
