FIELD: the invention may be used for protection of environment.
SUBSTANCE: On the first step the exhaust gases are set in contact with a recirculated liquid melt of urea holding predecessors of melamine and NH3, on the second step - with a raw liquid melt of melamine. The gas washer has two stages located one above the other. The upper section of the low stage has a sprayer, and the low section- a gas distributor. The upper section of the upper stage has a sprayer and one or more plates with chaffers located opposite it.
EFFECT: improves purification of gases exhausting from a reactor from melamine and other admixtures, increases energy effectiveness of the process of the melamine synthesis process due to better usage of the heat of exhaust gases.
