Zusammenfassung: | The utility model discloses a cooling water circulation recovery device utilized during production of dinitrodiazophenol. The cooling water circulation recovery device utilized during the production of dinitrodiazophenol resolves the technical problem that a great number of water resources are wasted during the production of the dinitrodiazophenol and difficulty of treating waste water is increased. The cooling water circulation recovery device comprises a small recovery pool, a pump and a big multilevel recovery pool which are sequentially communicated with each other. The small recovery pool and the pump are on the same surface with an inner waterway pipe network of a production system, and a certain height difference is between the big multilevel recovery pool and the inner waterway pipe network of the production system. The small recovery pool is communicated with an outlet of a cooling pipe of a reduction reaction tank of the inner waterway pipe network of the production system and an outlet of a cooling |
