Abstract
The utility model belongs to the technical field of thermal treatment, a radiation cone flue gas waste heat recovery utilizes high-efficient heat treatment furnace is related to. The chimney is arranged at the top of the heat treatment furnace and communicated with the heat treatment furnace; the radiation cone is arranged at the top in the heat treatment furnace; an air preheater is arranged in the chimney; the outlet pipeline of the air blower is connected with the inlet of the air preheater, and the outlet pipeline of the air preheater is connected with the combustor through an air duct. The high-temperature flue gas of the heat treatment furnace exchanges heat with air through an air preheater, and the cold flue gas after heat exchange is exhausted through a chimney; the cold air is changed into high-temperature air after heat exchange with the high-temperature flue gas through the air preheater, and the high-temperature air is sent into the combustor for combustion supporting. The waste heat of the flue gas is utilized to heat the air, so that the fuel is fully combusted, the temperature of the discharged flue gas is reduced, the heat efficiency of the furnace is improved, the energy consumption is reduced, the exhaust emission is reduced, and the energy-saving and environment-friendly effects are realized.
Description
Technical Field
The utility model belongs to the technical field of heat treatment, especially, relate to a radiation cone flue gas waste heat recovery utilizes high-efficient heat treatment furnace.
Background
The heat treatment furnace is a general term for an industrial furnace for performing various metal heat treatments on metal workpieces. The temperature is generally lower than that of the heating furnace. Various types of heating furnaces can be used as the heat treatment furnace, but the furnace temperature, the furnace atmosphere, and the like are required to be controlled strictly. The heat treatment furnace is usually heated by using a gas fuel. The prior heat treatment furnace has the problems of high exhaust gas temperature, low heat efficiency, uneven heating of heat treatment pieces and the like.
Disclosure of Invention
The utility model aims at overcoming the problems and providing a radiation cone flue gas waste heat recovery and utilization high-efficiency heat treatment furnace with uniform heating and high heat efficiency.
The technical scheme of the utility model:
a radiation cone flue gas waste heat recycling high-efficiency heat treatment furnace mainly comprises a heat treatment furnace 1, a burner 2, an air duct 3, an air preheater 4, a chimney 5, a radiation cone 6 and a blower 7; the chimney 5 is arranged at the top of the air preheater 4 and communicated with the air preheater 4; the radiation cone 6 is arranged at the top in the heat treatment furnace 1; the chimney 5 is arranged above the air preheater 4; an outlet pipeline of the blower 7 is connected with an inlet of the air preheater 4, and an outlet pipeline of the air preheater 4 is connected with the combustor 2 through the air duct 3.
As a further improvement, the air heater 4 be shell-and-tube heat exchanger, its both ends all are equipped with the tube sheet, are fixed with the heat exchange tube between the tube sheet of both ends, are equipped with air inlet and air outlet on the casing of air heater 4.
As a further improvement of the utility model, the heat exchange tube is an inner finned tube and an outer finned tube.
As a further improvement of the present invention, a baffle plate is provided on the shell side of the air preheater 4.
As a further improvement of the utility model, the tube side of the air preheater 4 is a flue gas channel and the shell side is an air channel.
The high-temperature flue gas of the heat treatment furnace exchanges heat with air through the air preheater, and the cold flue gas after heat exchange is emptied through the chimney; the cold air is changed into high-temperature air after heat exchange with the high-temperature flue gas through the air preheater, and the high-temperature air is sent into the combustor for combustion supporting. The waste heat of the flue gas is utilized to heat the air, so that the fuel is fully combusted, the temperature of the discharged flue gas is reduced, the heat efficiency of the furnace is improved, the energy consumption is reduced, the exhaust emission is reduced, and the energy-saving and environment-friendly effects are realized.
The increase of the radiation cone reduces the loss of radiation heat, so that the workpiece is heated more uniformly. The radiation cone at the top changes the internal circulation of the flue gas at the upper part of the heat treatment furnace, increases the internal circulation of the flue gas in the radiation chamber, and reduces the exhaust gas temperature by about 10 percent on the original basis.
