Tail gas heat energy efficient recovery equipment of rotary furnace and application method thereof

Abstract

The invention relates to tail gas heat energy efficient recovery equipment of a rotary furnace. The equipment comprises a tail gas buffer discharge tank, a heat energy recovery mechanism and an air compressor; the bottom of the tail gas buffer tank communicates to a tail gas discharge pipe of the rotary furnace through a corresponding tail gas inlet pipe; a corresponding exhaust pipe is arranged at the top of the tail gas buffer tank; the heat energy recovery mechanism comprises a heat exchange intake pipe and a heat exchange exhaust pipe tightly penetrating through the upper and lower ends ofthe tail gas buffer tank; a corresponding heat exchange cylinder communicates between the heat exchange intake pipe and the heat exchange exhaust pipe; the diameter of the heat exchange cylinder is larger than the diameter of the heat exchange exhaust pipe; the diameter of the heat exchange exhaust pipe is larger than the diameter of the heat exchange intake pipe; the heat exchange exhaust pipe is connected to an intake port of the air compressor; and an exhaust port of the air compressor is connected to an intake pipe of the rotary furnace through a corresponding pressure reducing valve. Theequipment can effectively and greatly improve the reutilization rate of tail gas heat energy of the rotary furnace, and is simple in structure and low in operation and production cost.

Description

technical field [0001] The invention relates to a tail gas heat energy recovery equipment for rotary furnace production, in particular to a high-efficiency recovery equipment for tail gas heat energy of a rotary furnace and a use method thereof. Background technique [0002] Rotary furnace, also known as hot air rotary furnace, refers to a kind of equipment that uses a variety of different energy sources to heat the combustion chamber, sends hot air into the furnace through a heat exchanger and a fan, and then bakes the items in the furnace. The hot air enters the furnace body to bake the rotating items, and then it is discharged along the exhaust pipe of the rotary furnace. Since the exhaust gas contains moisture and other substances produced by the baking of the items, it cannot be directly recycled. At present, the thermal energy reuse of the tail gas of the rotary furnace is generally contacted with the tail gas through various heat exchangers, and then heat exchange is ...
