FIELD: treatment of burnt gas. SUBSTANCE: refrigerating plant for exhaust gas includes tower to treat exhaust gas which lower part has inlet for exhaust gas carrying moisture and which upper part has spray gun for water treatment of exhaust gas, heat exchanger to cool water for treatment of exhaust gas, tower cooler to generate cooling water by way of evaporation of water with water spray gun and by-passes. Circulation by-pass communicates lower part of tower that treats exhaust gas with water spray gun treating exhaust gas in lower part of tower. Heat exchanger is positioned at point of abovementioned circulation by-pass. Circulation by-pass communicates with one end with lower part of tower cooler and with other end with water spray gun in cooling tower via heat exchanger to secure supply of cooling water that cools water in heat exchanger. Circulation by-pass for water to treat exhaust gas communicates with use of by-pass of additional water with lower part of tower cooler that supplies water to treat exhaust gas. EFFECT: reduced to minimum load of treatment of waste water, decreased amount of water supplied to tower cooler and reduced to minimum frequency of blow-through of tower cooler. 2 cl, 5 dwg, 5 tbl |
