This series air heat exchanger is a kind of energy saving and environmental protection equipment which uses the exhaust heat of hot blast stove. The tail gas of hot blast stove is then transported through the pipe to the dust removal equipment through the heat exchanger, and then discharged into the atmosphere by the dust removal equipment. When the hot flue gas passes through the heat exchanger, it exchanges heat with the clean air through the air duct, so as to preheat the combustion-supporting air, improve the temperature of the combustion-supporting air, recover waste heat, reduce gas consumption and save energy; At the same time, the temperature of the hot flue gas decreases rapidly after heat exchange, so that the temperature of the flue gas entering the dust removal equipment is moderate, which plays a better protective role for the dust removal equipment, so as to extend the service life of the equipment.
(1) Simple structure, wide adaptability, can be used in multiple fields of waste heat utilization;
(2) High flexibility, can be used alone, can also be used in association with other heat exchangers;
(3) The air is preheated and then enters the furnace to save energy;
(4) The hot gas enters the dust removal equipment through heat exchange, and the temperature is reduced, which is conducive to the protection of the equipment;
(5) Easy to use, simple maintenance, with high use value.
