Abstract

The invention relates to a recycling processing system of cold-state carbon steel oxide scale powder suspension. Oxide scale powder suspension flows into a sand liquid separation pool through a liquid inlet; the oxide scale powder suspension in the sand liquid separation pool flows into an oxide scale powder suspension tank through a liquid weir outlet; a liquid outlet of the oxide scale powder suspension tank is connected with a raw water lift pump; an outlet pipe of the raw water lift pump is connected with a suspension pipe mixer; an outlet of the suspension pipe mixer is connected with a flowmeter; an outlet of the flowmeter is connected with a coagulation flocculation reaction pool; an outlet of the coagulation flocculation reaction pool is connected with an inclined plate sedimentation pool; an outlet of the inclined plate sedimentation pool is connected with a filtering water tank; a liquid outlet of a clear water tank is connected with a clear water lift pump; the clear water lift pump is connected with an inlet of a cloth bag filter; an outlet of the cloth bag filter is connected with a sand liquid mixing device. The system of the invention is stable in processing effect, low in production operation cost, simple in operation running, and high in automation degree.

Description

【Technical field】 [0001] The invention relates to the technical field of water treatment, in particular to a recycling treatment system for cold carbon steel scale powder suspension. 【Background technique】 [0002] As my country's basic industry, the iron and steel industry has developed rapidly since the reform and opening up, and has been in a high-speed development stage in recent years. However, the iron and steel industry is an industry with high energy consumption, high resources and high pollution, and its water consumption is huge, accounting for about 14% of the national industrial water consumption. [0003] In July 2005, the National Development and Reform Commission issued the "Iron and Steel Industry Development Policy", which put forward higher goals and more specific requirements for the iron and steel industry to develop circular economy, save energy and resources, and take the road of sustainable development. Under these conditions, low energy consumption, ...
