Working principle of the utility model is: in the process of tempering furnace work, the workpiece in the tempering furnace sent to tempering furnace discharging mouth, the installation of the heat exchanger on the top of the discharging mouth 4 heat recovery discharging mouth, at the same time, fan blowing air through the blast pipe heat exchanger from 4 cold air inlet into the heat exchanger 4, after heat exchanger in the recovery of heat to heat the cold wind, heated hot air through the heat exchanger of 4 hot air outlet through hot air into the duct to the tempering furnace furnace 1 to combustion of natural gas, effectively improve the combustion efficiency, save energy, At the same time in the working process of the tempering furnace oxygen concentration detector on tempering furnace furnace internal oxygen concentration for testing, when the inside of the furnace body at low oxygen concentrations, the oxygen tube on the electromagnetic valve is opened, an oxygen tank internal oxygen are fed into the hot air into the duct 7 into the furnace internal combustion, further improve the combustion efficiency, make the combustion more sufficient, effectively reduce the tempering furnace flue gas, the content of harmful gas in energy saving and environmental protection; Tempering furnace in the process of the work, to remove the high temperature of tempering furnace soot into the combustion chamber, at this point, the pipe cross section increases suddenly, lampblack through speed decreases, while the burner work produce high-temperature fire, smoke through the burner flame covered area, by the high temperature burning, burning itself, soot in the retention period of the combustion chamber can be fully effective burning decomposition, decomposition products to meet the requirements of environmental emissions of nitrogen, oxygen, water vapor, carbon dioxide and nitrogen oxides, such as gas by the gas discharge tube after discharge, no harmful gas pollution, protect the environment, accord with the demand of the modern industrial production.
For technicians in the field, it is obvious that the utility model is not limited to the details of the above exemplary embodiments and can be realized in other concrete forms without deviating from the spirit or basic features of the utility model. Thus, in all respects, the embodiments should be considered exemplary and non-restrictive, and the scope of the utility model is limited by the attached claims rather than the above description, and is therefore intended to include in the utility model all changes within the meaning and scope of the equivalent elements falling within the claims. Any appended drawing of the claim shall not be regarded as a claim to which the limitation relates.
In addition, should understand, although this manual according to the method described, but not every method contains only an independent technical scheme, the directions of this narrative is only for clarity, the field technical specifications shall be taken as a whole, the implementation example of the technical scheme can also be properly combined, form the field technicians can understand other implementation methods.

With a flue gas treatment plant energy saving tempering furnace, including tempering furnace furnace and tempering furnace discharging mouth, its characteristics is described in the tempering furnace discharging mouth is set in the bottom of the tempering furnace furnace, tempering furnace discharging mouth are installed on the bracket of recovery of waste heat, waste heat recovery of bracket is installed above the heat exchanger, tempering furnace furnace left with blower, the blower connected with a blast pipe, blast pipe at the other end and connected to the air cooling air inlet of the heat exchanger, heat exchanger of air outlet connected with a hot air into the duct, hot air into the duct at the other end and tempering furnace furnace inlet connection, tempering furnace on the inner wall of the furnace body is equipped with oxygen concentration detector, Tempering furnace body is equipped with an oxygen tank on the right side, oxygen tanks through the oxygen supply tube with hot air into the duct connected to tempering furnace furnace described the exhaust air outlet duct connected with a lampblack, lampblack duct right end connected to the combustion chamber and combustion chamber of the lateral has a combustion chamber shell, is equipped with high temperature resistant layer between combustion chamber and combustion chamber shell, combustion chamber upper left open hole, the combustion chamber shell outer wall and the hole is corresponding with the upper end cover, inside the hole insert have a high temperature resistant steel, high temperature resistant steel pipe bottom and connected to the internal combustion chamber, high temperature resistant steel pipe at the other end connected to the burner, the combustion chamber right end connection of gas discharge tube.
2. The oxygen supply pipe is provided with a solenoid valve.
3. The material of the high-temperature resistant layer is quartz sand.
4. The burner comprises an igniter, a gas tank, a gas delivery pipeline and a fan.
5. According to the energy-saving return furnace with smoke treatment device mentioned in Claim 4, its characteristics lie in that the fan is provided with a normally closed switch connected with the burner power switch.
With flue gas treatment plant energy saving tempering furnace, including the tempering furnace furnace and tempering furnace discharging mouth, tempering furnace discharging mouth is set in the bottom of the tempering furnace furnace, tempering furnace discharging mouth are installed on the bracket of recovery of waste heat, waste heat recovery of bracket is installed above the heat exchanger, tempering furnace furnace left with blower, the blower connected with a blast pipe, blast pipe at the other end and connected to the air cooling air inlet of the heat exchanger, the utility model with flue gas treatment plant energy saving tempering furnace, can back to the recovery of waste heat of the stove discharging outlets recycle heat exchanger to heat drum into the combustion air in the combustion chamber, The combustion efficiency of the gas can be effectively improved after the air sent into the combustion chamber is heated, and oxygen can be pumped in the hot air blowing process, which further improves the combustion efficiency and saves energy. In addition, the exhaust gas of the furnace can be fully burned, which meets the emission requirements and protects the environment.
