The heat recovery system of the paint booth mainly recovers the heat from the exhaust gas discharged from the paint booth through a heat exchange device, which is used to preheat the fresh air or other heating needs entering the paint booth, in order to achieve energy-saving purposes.
In the heat exchanger, the high-temperature exhaust gas discharged from the paint booth and the fresh air (or other heated medium) entering the paint booth flow on both sides of the partition wall, and heat is transferred through the partition wall. Due to the lack of direct contact between exhaust gas and fresh air, the mixing of the two is avoided, ensuring the cleanliness of the air. The heat of high-temperature exhaust gas is transferred to the partition wall, which then transfers the heat to fresh air, raising the temperature of the fresh air and achieving heat recovery and utilization.
