The heat recovery mode of the heat setting machine mainly uses gas-gas heat exchange during operation. In operation, the heat energy is recovered from the waste heat gas discharged from the setting machine and then effectively returned to the setting machine oven, so that Effectively realize the purpose of energy saving, the heat exchange mode is gas-gas heat exchange, and the common heat exchanger is heat pipe heat exchanger.
The heat setting machine fully utilizes the high-efficiency heat transfer performance of the heat pipe to a certain extent, and the high-temperature waste flue gas discharged from the device discharges heat through the heat-absorbing side of the heat exchanger, and the heat is quickly transmitted to the heat exchanger through the heat pipe. Exothermic side. The fresh air absorbs heat when passing through the heat release side of the heat exchanger, and the heated fresh air is sucked into the oven by the negative pressure in the setting machine oven, thereby achieving energy saving purposes.
The heat setting machine adopts gas-water heat exchange. In the process of operation, the heat is recovered from the waste heat gas discharged from the setting machine to generate hot water, so that the purpose of energy saving can be achieved, and the heat exchange mode is “gas-water”. "Heat exchange, the commonly used heat exchanger is a tube heat exchanger. The high-temperature waste flue gas discharged from the setting machine exchanges heat with the clean water through the heat exchanger, and the heated clean water is sent to the hot water tank for production needs. The heat of the hot water is the heat energy in the waste flue gas, which saves the fuel (burning coal, gas, etc.) or electric energy required for heating, thereby achieving energy saving purposes.
