The utility model discloses an air heating furnace smoke energy recycling system which comprises a combustion furnace body and an air blower. The combustion furnace body comprises a heat exchanging furnace body and a combustion hearth. A cold air inlet and a hot air outlet are formed in the heat exchanging furnace body. A smoke dust outlet is formed in the combustion hearth. A heat exchanger is further arranged at the position of the cold air inlet. The heat exchanger comprises a shell. An air inlet and an air outlet are formed in the shell. The air outlet is communicated with the cold air inlet. The air inlet is communicated with the air blower. A tubular heat exchanger is arranged on the shell. An air inlet and an air outlet are formed in the tubular heat exchanger. The air inlet of the tubular heat exchanger is communicated with the smoke dust outlet. The air outlet of the tubular heat exchanger is communicated with an exhaust fan. According to the air heating furnace smoke energy recycling system, high-temperature smoke dust coming out from the smoke dust outlet is used for pre-heating cold air at an opening of the air blower to enable hot air coming out from the hot air outlet to have the higher temperature, and therefore the heat exchanging efficiency is improved. In addition, the air heating furnace smoke energy recycling system has the advantages of being reasonable in structure and convenient to install.

The utility model content

The purpose of this utility model is to provide a kind of hot-blast stove fume energy recovery utilizing system, to for the cold air to blower mouth, carry out preheating from the high-temperature smoke that flue dust exports out, make from hot-blast outlet hot blast out and have higher temperature, thereby raising heat exchanging efficiency, and have characteristics rational in infrastructure, easy for installation.

For achieving the above object by the following technical solutions:

a kind of hot-blast stove fume energy recovery utilizing system, comprise burner block and air blast, described burner block comprises heat exchange body of heater and burning furnace, on the heat exchange body of heater, be provided with cold wind import and hot-blast outlet, the combustion furnace one's parents are provided with the flue dust outlet, it is characterized in that: in described cold wind import department, also be provided with heat exchanger, in heat exchanger, comprise housing, housing is provided with air inlet and air outlet, air outlet is communicated with the cold wind import, air inlet is communicated with air blast, at described housing, be provided with tubular heat exchanger, tubular heat exchanger is provided with air inlet and gas outlet, air inlet is communicated with the flue dust outlet, the gas outlet of tubular heat exchanger is communicated with air exhauster.

Described air exhauster exhaust outlet is communicated with air cleaning unit, and air cleaning unit comprises dust setting chamber and pneumatic filter; Described dust setting chamber comprises a cavity, at the top of cavity, be provided with import and escape pipe, import is communicated with the exhaust outlet of air exhauster by pipeline, the bottom of escape pipe is lower than the position of import, escape pipe is communicated with pneumatic filter by pipeline, in the bottom of described cavity, is provided with dust collection chamber.

Described pneumatic filter comprises clean room, air inlet pipe and exhaust outlet, and the air inlet pipe lower end stretches under liquid side to clean room, and exhaust outlet is arranged on the top of clean room.

The utility model is provided with heat exchanger between air blast and cold wind import, the thermal source of heat exchanger is provided by the flue dust of the high temperature that flue dust exports out, the flue dust of high temperature carries out preheating to the cold air that blows to burner block, cold air after preheating after heat exchange body of heater heating from hot-blast outlet out hot blast after relatively there is no preheating, have higher temperature, thereby promoted the heat exchanger effectiveness of burner block, the utility model has only been set up a heat exchanger, can realize the lifting of heat exchanger effectiveness, have characteristics rational in infrastructure, easy for installation.
