Steam recovery system and steam recovery process

The invention relates to a steam recovery system and a steam recovery process, aiming at saving water resources and reducing the production cost. The steam recovery system comprises a condenser, a main condensate pipe, a pump, a chemicals feeding device, a control valve, branched condensate pipes and heat exchangers, wherein a steam inlet is formed in one end of the main condensate pipe; from the steam inlet, the main condensate pipe is sequentially communicated with the condenser and the pump; the main condensate pipe connected with the water outlet end of the pump is further communicated with a group of parallel branched condensate pipes; each branched condensate pipe is connected with a heat exchanger; and the terminals of the branched condensate pipes are communicated with each other and connected with a user end by a connecting pipeline. According to the steam recovery system and the steam recovery process, after steam generated in the chemical production process is processed by added agents, dissolved oxygen and scale are removed from the water and the pH value of the water is adjusted, so that the water can be reused for production.
