More Information
Summary:The present invention provides a cracking furnace exhaust gas recycling method, which comprises the following steps: tempering, water-sealing and filtering the exhaust gas to reduce temperature of the exhaust gas, filtering out impurities of the exhaust gas, decreasing and adjusting pressure of the exhaust gas, mixing the exhaust gas with air to adjust the ratio of the exhaust gas to air, and finally sending the exhaust gas back to a cracking furnace for being used as fuel, thereby, the exhaust gas is not exhausted into the air. Therefore, the present invention can provide a rather eco-friendly exhaust gas recycling method.
