The waste heat treatment box passes through The gas pipeline is connected to the gas purification box, and the exhaust gas emitted from the heating furnace body passes through the activated carbon filter in the gas purification box for removal of impurities, and then accelerates into the waste heat treatment box under the action of the fan, and the high-heat gas heat is transferred to the heat dissipation The heat sink dissipates heat to the first heating chamber and the second heating chamber in order to achieve thermal balance, thereby keeping the heat storage chamber at a high temperature. The exhaust gas after absorbing the heat passes through the breather pipe and is discharged from the exhaust pipe.

In the above-mentioned prior art, the functions of utilizing the waste heat of the heating furnace and removing impurities can also be realized. However, firstly, when utilizing the waste heat in the above-mentioned prior art, the exhaust gas is first removed of impurities and then uses the waste heat. High-heat The gas may cause the activated carbon to spontaneously ignite or the high temperature may reduce the adsorption of the activated carbon, resulting in poor impurity removal effect in the exhaust gas.

Based on this, on top of the existing environmentally friendly heating furnace exhaust gas waste heat reuse technology, there are also Room for improvement.
