The invention discloses a closed type air heating furnace comprising a closed flame heat collection chamber tube, a closed air heat collection device and a closed air heating furnace outer wall. The flame heat collection chamber tube comprises a flame combustion chamber and a flame heat collection tube, and the air heat collection device comprises an air heat collection tube and an air heat collection air duct, wherein the air heat collection air duct is formed by the outer wall of the flame combustion chamber and the outer wall of the air heating furnace. The air heat collection tube is built in the flame combustion chamber, one end of the air heat collection tube is connected with an air supply tube in a closed mode, and the other end of the air heat collection tube is fixed to the inner wall of the flame combustion chamber. Primary hot air flowing out of the air heat collection tube penetrates through a hot air outlet in the flame combustion chamber and then enters the air heat collection air duct, secondary hot air in the air heat collection air duct is discharged through a hot air discharging port in the outer wall of the air heating furnace, and an air supply fan is connected to the air supply tube in an insertion mode. The flame heat collection tube is arranged in the air heat collection air duct and communicated with the flame combustion chamber, and a combustor is connected to the flame combustion chamber in an insertion mode. The problems that in the prior art, the thermal utilization rate of an air heating furnace is low, environment pollution is severe, and the size is huge are solved.
Description
technical field [0001] The invention belongs to the technical field of drying machinery, in particular to a closed hot blast stove. Background technique [0002] At present, most of the hot blast stoves on the market use coal-fired boilers. The main principle is: the coal burns in the furnace to generate heat to heat the air duct, and the wind carries the heat out through the air duct, and then it is introduced into the drying warehouse through the pipe to dry or dry the material. It is directly introduced into the room that needs to be heated through the pipeline, and the indoor temperature is heated accordingly. [0003] However, the existing coal-fired boilers have the following problems: [0004] 1. The boiler body is huge, and the boiler itself is a large radiator, and the heat passes through the boiler furnace at one time, so the heat utilization rate of the boiler is low. Further, because the furnace is separated from the drying chamber, a large amount of heat on th...
