The solvent sprayed out of the spray header 4 is a solvent which can be dissolved with harmful substances in the gas entering from the gas inlet pipe 1 physically or can generate chemical reaction.
According to different baking objects in the oven, main harmful substances in gas extracted from the oven are analyzed in advance, and then a proper solvent is selected according to the principle of similarity and intermiscibility or the principle of chemical reaction.
According to the principle of similar compatibility of the solvent, a solvent physically compatible with the harmful substance in the gas entering from the gas inlet pipe 1 may be used, for example, if the harmful substance in the gas is very soluble in water, the solvent may be water. Other solvents which are very soluble with harmful substances in the gas can be selected according to requirements. The sprayed solvent is fully contacted with the gas, harmful substances in the gas can be dissolved into the solvent, and gas purification is realized.
