This invention provides an energy-saving
blast furnace gas temperature regulation device, applied at the
blast furnace gas outlet. It includes a gravity
dust collector, a radiator, a dust collection bag, and a
turbine. The gravity
dust collector is connected at one end to the
blast furnace gas outlet and at the other end to the radiator, used for preliminary removal of large particulate impurities from the
blast furnace gas. The radiator is connected at one end to the gravity
dust collector and at the other end to the dust collection bag, used to control the temperature of the
blast furnace gas and prevent damage to the dust collection bag. The dust collection bag is connected at one end to the radiator and at the other end to the
turbine, used to remove impurities from the
blast furnace gas, completing the purification process. The
turbine, connected to the dust collection bag, converts the pressure and
thermal energy of the blast furnace gas into rotational
mechanical energy to drive a generator. This invention effectively regulates the temperature of the blast furnace gas, simultaneously treating the gas and enabling its recycling.
