This paper mainly introduces the newly added waste hydrogen recovery device of the bell annealing furnace.This device includes pipeline switching device,filtering device,pressure increasing device and processing device.Waste hydrogen is collected,stored,filtered and purified.Waste hydrogen is sent to the coke oven gas hydrogen production station through pressurized equipment,and mixed with refined coke oven gas,as hydrogen production raw material for reuse.S7-1500 is used to control the process flow of waste hydrogen recovery.Human-machine interface was created on the operator station to display various process parameters and alarm,real-time monitoring of the production process At the same time,the program interlock protection ensures the safe and reliable operation of the waste hydrogen recovery system,and achieves the perfect combination with the original bell annealing furnace system.The operation of this device has achieved the recovery and utilization of waste hydrogen during the annealing process,not only reducing production costs but also avoiding environmental pollution It has economic and social benefits realizing the desired effect.
