Background technology
Traditional medium and small steel part Forge Heating and formwork roasting are that fuel heats workpiece with the coal, owing in adding coal-fired process, can make the temperature fluctuation in the burner hearth bigger, poor temperature uniformity to the workpiece heating, cause the quality instability of workpiece, and coal also exists problems such as energy consumption is big, the thermal efficiency is low, contaminated environment in varying degrees in combustion process.For this reason, the solution of taking at present is to act as a fuel with coal gas, fuel oil workpiece is heated, and efficiently solves to use the temperature fluctuation of coal heated parts existence bigger, to the drawback of workpiece homogeneous heating difference.But because it is under the prerequisite of not carrying out any The pre-heat treatment workpiece directly to be heated, and the high-temperature gas (waste gas) that produces in the heating process just do not made full use of directly enters atmosphere, cause heat energy loss big, the thermal efficiency is low.Owing to all can not realize the continual continuous heating of workpiece for above-mentioned two kinds, so production efficiency is lower.
Technology contents
The purpose of this utility model promptly produces thus, proposes a kind of high-efficiency environment friendly liquefied gas heating furnace.This heating furnace is high-efficiency environment friendly, liquefied gas factor of created gase height, homogeneous heating not only, and thermal efficiency height is convenient to operation, and can realize the continuous heating to workpiece.
For achieving the above object, the technical solution of the utility model is as follows: it is by body of heater, burner hearth, burner, air heat exchanger, preceding fire door and back fire door constitute, burner hearth comprises the thermal treatment zone and the preheating zone of connection, its perforation is installed in the body of heater, charging aperture is positioned at the preheating zone, discharging opening is positioned at the thermal treatment zone, be provided with burner and air heat exchanger in the body of heater upper end, burner is positioned at the thermal treatment zone of burner hearth and is communicated with the thermal treatment zone, air heat exchanger is positioned at the preheating zone of burner hearth and is communicated with the preheating zone, the inlet end of air heat exchanger is connected with blower fan by air duct, and the outlet side is connected with burner by air duct.
The utility model also is provided with water-to-water heat exchanger and liquid gas vaporization device, water-to-water heat exchanger is arranged on the upper end of air heat exchanger, the liquid gas vaporization device is that heat medium, heating tube and liquefied gas pipeline are set in a vaporization box, the inlet end of heating tube and water outlet end are communicated with the inlet end and the water outlet end of water-to-water heat exchanger respectively, the air inlet end of liquefied gas pipeline is connected with the liquefaction source of the gas, and its gas outlet end is connected with burner.
The utility model reasonable in design, because burner is arranged on the top, burner hearth is little, the calorific intensity of unit are is big, because the preheating zone and the heat exchanger of design can carry out The pre-heat treatment to workpiece, liquefied gas and air, thereby made full use of the waste heat of high-temperature gas, the thermal efficiency is greatly improved.Because the continuous heating that it can be realized workpiece is heated evenly workpiece, the quality of workpiece, workman's efficiency are improved.And it has adopted the liquid gas vaporization device, and the gas forming amount that can improve liquefied gas is with energy savings.
