[0002] At present, the existing air preheater is the heating surface where the flue gas in the flue at the tail of the boiler preheats the air before entering the boiler to a certain temperature through the internal cooling fins, which is used to improve the heat exchange performance of the boiler and reduce energy consumption. , when the existing air preheater is used, heat is easy to be dissipated, and the heat preservation effect is poor, resulting in low heat conversion efficiency. The thermal device cannot work normally, greatly affecting work efficiency

The invention discloses an air preheating device of an energy-saving boiler. The air preheating device comprises a housing cover, a thermal insulation layer, an air inlet and an air outlet, wherein the air inlet is formed in the left side of the housing cover; the air outlet is formed in the right side of the housing cover; the thermal insulation layer is covered at the periphery of the inner wallof the housing cover; carbon dioxide is filled in the thermal insulation layer; a net-shaped smoke tube is arranged in the housing cover; the top end of the net-shaped smoke tube penetrates through the top end of the housing cover; the bottom end of the net-shaped smoke tube penetrates through the bottom end of the housing cover; the bottom end of the net-shaped smoke tube communicates with the top end of a gas collecting cover; the bottom end of the gas collecting cover communicates with a smoke discharge tube; and the left side of the bottom end of the gas collecting cover is fixedly equipped with a supporting post. According to the air preheating device disclosed by the invention, the thermal insulation cover is covered at the periphery of the inner wall of the housing cover, carbon dioxide is filled inside the thermal insulation layer, very good thermal-insulation effect on tail gas conveyed by the smoke tube is achieved, and heat in waste gas is prevented from being lost in air,and therefore, the air preheating device is relatively practical, and is suitable for being widely popularized and used.
Description
technical field [0001] The invention relates to an air preheating device, in particular to an air preheating device for an energy-saving boiler. Background technique [0002] At present, the existing air preheater is the heating surface where the flue gas in the flue at the tail of the boiler preheats the air before entering the boiler to a certain temperature through the internal cooling fins, which is used to improve the heat exchange performance of the boiler and reduce energy consumption. , when the existing air preheater is used, heat is easy to dissipate, and the heat preservation effect is poor, resulting in low heat conversion efficiency. The thermal device cannot work normally, greatly affecting work efficiency. Therefore, we propose an energy-saving boiler air preheating device. Contents of the invention [0003] The main purpose of the present invention is to provide an air preheating device for an energy-saving boiler. The inner wall of the shell is wrapped w...
