Air cooling coupled heating furnace kiln smoke discharging deep condensate water demisting system

Abstract

The invention discloses an air cooling coupled heating furnace kiln smoke discharging deep condensate water demisting system. The air cooling coupled heating furnace kiln smoke discharging deep condensate water demisting system comprises a first-level waste heat recycling heat exchanger, a waste heat deep recycling heat exchanger, a smoke condenser and a heater. The first-level waste heat recycling heat exchanger is used for recycling smoke waste heat. The waste heat deep recycling heat exchanger is used for conducting deep recycling on the smoke waste heat. The smoke condenser is used for conducting condensing demisting treatment on smoke. The heater is used for conducting heating treatment on the smoke obtained after condensing treatment. The waste heat deep recycling heat exchanger is in heat transfer connection with the heater, and heat collected by the waste heat deep recycling heat exchanger is conveyed to the heater. By means of the air cooling coupled heating furnace kiln smokedischarging deep condensate water demisting system, smoke waste heat recycling and smoke water saving demisting treatment can be achieved, cold air is utilized for condensing wet smoke, and the condensation cost can be reduced; and through the manner of condensing mixing and heating, the demising reliability is further guaranteed, the water saving benefits are improved, and meanwhile certain environment protection benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of furnace flue gas treatment and water saving and energy saving, in particular to an air-cooled coupled heating furnace smoke deep condensate and fog elimination system. Background technique [0002] According to the national environmental protection requirements, the exhaust fumes of industrial furnaces need to be purified before they can be discharged. At present, the exhaust gas of industrial kilns is usually saturated wet flue gas, and the phenomenon of "white smoke" will appear in the atmosphere, which will not only affect the normal work of the surrounding residents It will also cause environmental pollution. my country is one of the countries with the poorest water resources. Recycling water resources from wet flue gas will not only bring certain water-saving benefits, but also meet the needs of my country's energy-saving and emission-reduction strategies. Therefore, it has become a technical proble...
